The accompanying notes are an integral part of these unaudited condensed consolidated financial statements.

Aptevo Therapeutics Inc. (Aptevo, we, us, or the Company) is a clinical-stage, research and development biotechnology company focused on developing novel ~~oncology (cancer)~~immunotherapeutic candidates for the treatment of different forms of cancer. We have developed 2 versatile and ~~hematology (blood disease) therapeutics to meaningfully improve patients’ lives.~~enabling platform technologies for rational design of precision immune stimulatory drugs. Our ~~core~~lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527 and APVO603, were developed using our ADAPTIR™ modular protein technology isplatform. Our preclinical candidate APVO442 was developed using our ADAPTIR-FLEX™ modular protein technology platform.

We are currently trading on the ~~ADAPTIR™ (modular protein technology) platform. We currently~~Nasdaq Capital Market under the symbol “APVO.”

The accompanying financial statements have ~~one revenue-generating product~~been prepared on a basis that assumes we will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ~~area~~normal course of ~~hematology,~~business. For the three months ended March 31, 2022 and 2021, we had a net loss of $7.7 million and $7.3 million, respectively. We had an accumulated deficit of $221.8 million as ~~well as various investigational stage product candidates~~of March 31, 2022. For the three months ended March 31, 2022, net cash used in our operating activities was $5.1 million. We have suffered recurring losses from operations and negative cash flows from operating activities. We believe that our existing cash resources, the Investment Amount and Milestone Amounts related to Royalty Purchase Agreement with HCR, Purchase Agreement with Lincoln Park, the cash to be generated from future deferred payments and milestones, release of restricted cash securing letters of credit, and funds available to us from the remaining principal balance of the Credit Agreement with MidCap Financial will be sufficient to meet our projected operating requirements and debt service for at least twelve months from the date of issuance of these financial statements. We may choose to raise additional funds to support our operating and capital needs in the ~~area of immuno-oncology.~~future.

~~On September 28, 2017, Aptevo completed the sale of its hyperimmune business which consisted of the following products:~~ ~~WinRho~~^® ~~SDF for autoimmune platelet disorder~~We continue to face significant challenges and ~~hemolytic disease of the newborn; HepaGam B~~^® ~~for the prevention of Hepatitis B following liver transplantation~~uncertainties and, ~~for treatment following hepatitis B exposure; and VARIZIG~~^® ~~for treatment following exposure to varicella zoster virus for individuals with compromised immune systems (Hyperimmune Business). As of September 30, 2017, the Hyperimmune Business met all the conditions to be classified~~ as a ~~discontinued operation since~~result, our available capital resources may be consumed more rapidly than currently expected due to: (a) changes we may make to the ~~sale~~business that affect ongoing operating expenses; (b) changes we may make in our business strategy; (c) changes we may make in our research and development spending plans; (d) potential decreases in our expected milestone and deferred payments from Medexus Pharmaceuticals Inc. (Medexus) with respect to IXINITY; (e) whether and to what extent future proceeds are received under our Royalty Purchase Agreement; and (f) other items affecting our forecasted level of ~~Hyperimmune Business represented~~expenditures and use of cash resources. We may attempt to obtain additional funding through our existing equity sales agreement with Lincoln Park or our Equity Distribution Agreement with Piper Sandler & Co (Piper Sandler), or other public or private financing, collaborative arrangements with strategic partners, or through credit lines or other debt financing sources to increase the funds available to fund operations. However, we may not be able to secure such funding in a ~~strategic shift~~timely manner or on favorable terms, if at all. Furthermore, if we issue equity or debt securities to raise additional funds, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences, and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing, or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that ~~will have a major effect on the Company’s~~are not favorable to us. Without additional funds, we may be forced to delay, scale back, or eliminate some of our research and development activities or other operations and ~~financial results. The Company will not have further significant involvement~~potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals may be adversely affected. Given the global economic and geopolitical climate and additional or unforeseen effects from the ongoing COVID-19 pandemic, we may experience delays or difficulties in the ~~operations~~financing environment and raising capital due to economic uncertainty.

Basis of the discontinued Hyperimmune Business. The operating results of the Hyperimmune Business are reported as income from the discontinued operations, both pre-tax and net of tax, in the condensed consolidated statements of operations for all periods presented. The gain recognized on the sale of the Hyperimmune Business is presented in income (loss) from discontinued operations, both pre-tax and net of tax, in the condensed consolidated statement of operations. In addition, the consolidated and condensed balance sheets as of December 31, 2016, the assets and liabilities held for sale have been presented separately. See Note 2 - Sale of Hyperimmune Business for additional information.Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). These unaudited ~~interim~~ condensed consolidated financial statements ~~have been prepared on the same basis as the audited financial statements and~~ include all adjustments, which include normal recurring adjustments, necessary for the fair presentation of the Company’s financial position.

On August 6, 2015, Emergent BioSolutions Inc., (Emergent or former parent), announced a plan to separate into two independent publicly traded companies. To accomplish this separation, Emergent created Aptevo Therapeutics Inc. or Aptevo, to be the parent company for the development-based biotechnology business focused on novel oncology and hematology therapeutics. Aptevo was incorporated in Delaware in February 2016 as a wholly owned subsidiary of Emergent. To effect the separation, Emergent made a pro rata distribution of Aptevo’s common stock to Emergent’s stockholders on August 1, 2016. We are currently trading on the NASDAQ Global Market under the symbol “APVO.”

~~Prior to August 1, 2016, the~~ These unaudited interim consolidated financial statements ~~were prepared on a “carve-out” basis for~~should be read in conjunction with the ~~purpose of presenting Aptevo’s financial position, results of operations, and cash flows, and were derived from Emergent’s~~audited consolidated financial statements as of and ~~accounting records. Aptevo did not operate as a standalone entity in~~for the ~~past~~year ended December 31, 2021, and ~~accordingly~~ the selected financial data presented herein is not necessarily indicative of Aptevo’s future performance and does not reflect what Aptevo’s performance would have been had Aptevo operated as an independent publicly-traded company prior to August 1, 2016. The consolidated financial statements reflect Aptevo’s financial position, results of operations, and cash flows as a separately operated business in conformity with GAAP post the August 1, 2016 spin-off.

~~Prior to August 1, 2016, the consolidated financial statements~~notes thereto, which are included an allocation of certain assets and liabilities that have historically been held at the Emergent corporate level but which were specifically identifiable or allocable to Aptevo. All Aptevo intracompany transactions and accounts have been eliminated. All intercompany transactions between Aptevo and Emergent are considered to be effectively settled in the consolidated financial statements at the time the transaction was recorded. The total net effect of the settlement of these intercompany transactions is reflected in the consolidated statement of cash flows as a financing activity and in the consolidated balance sheet as a net investment from Emergent. As of August 1, 2016, in connection with the separation and distribution, Emergent’s investment in the Company’s ~~business was redesignated as stockholder’s equity and allocated between common stock and additional paid-in capital based~~Annual Report on ~~the number of shares issued at the distribution date.~~

Prior to August 1, 2016, Aptevo’s consolidated financial statements included an allocation of expenses related to certain Emergent corporate functions, including senior management, legal, human resources, finance, information technology, and quality assurance. These expenses were allocated to Aptevo based on direct usage or benefit where identifiable, with the remainder allocated on a pro rata basis of expenses, headcount, square footage, or other measures. Aptevo considers the expense allocation methodology and results to be reasonable for all periods presented. However, the allocations may not be indicative of the actual expense that would have been incurred had Aptevo operated as an independent, publicly-traded companyForm 10-K for the ~~periods presented.~~

Prior to August 1, 2016, the income tax amounts in these consolidated financial statements were calculated based on a separate return methodology and presented as if Aptevo’s operations were a standalone taxpayer in each of its tax jurisdictions.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates and changes in these estimates are recorded when known.

The unaudited condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries: Aptevo Research and Development LLC and Aptevo BioTherapeutics LLC (for the period prior to its sale on February 28, 2020). All intercompany balances and transactions have been eliminated.

The preparation of financial statements in conformity with GAAP requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent liabilities in the unaudited condensed consolidated financial statements and accompanying notes. Estimates are used for, but not limited to, forecasted royalties, effective interest rates, clinical accruals, useful lives of equipment, commitments and contingencies, and stock-based compensation. Given the global economic and geopolitical climate and additional or unforeseen effects from the ongoing COVID-19 pandemic, these estimates are becoming more challenging, and actual results could differ materially from those estimates.

~~Aptevo records accounts receivable~~Liability Related to Sale of Royalties and Non-Cash Interest Expense

On March 30, 2021, the Company entered into and closed a Royalty Purchase Agreement (the Royalty Purchase Agreement) with an entity managed by HealthCare Royalty Management, LLC (HCR) pursuant to which the Company sold to HCR the right to receive royalty payments made by Pfizer Inc. (Pfizer) in respect of net sales of RUXIENCE. Under the terms of the Royalty Purchase Agreement, the Company received $35 million (the Investment Amount) at closing and the Company is eligible to receive additional payments in the aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022 and 2023 (collectively, the Milestone Amounts). The Company received the 2021 milestone payments in the collective amount of $10 million on March 8, 2022. The proceeds from these milestone payments, net of transaction costs, were recorded as an allowance for doubtful accounts based upon its assessment of collectability, and of applicable discounts. Aptevo performs ongoing credit evaluations of its customers and generally does not require collateral. As a result of its sale of its Hyperimmune Business in September 2017, accounts receivable net of an allowance for doubtful accounts has been revised to reflect the removal of its allowance for doubtful accounts, as the prior balance solelyadditional liability related to the ~~Hyperimmune Business. See Note 2, Sale~~sale of ~~Hyperimmune Business for additional information~~royalties on the ~~divestiture.~~consolidated balance sheet as of March 31, 2022. The Company is eligible to receive additional payments in the aggregate of up to $22.5 million based on achievement of sales milestones in 2022 and 2023. The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to receive 50% of royalty interest payments thereafter.

We treat the Royalty Purchase Agreement with HCR (see Note 7) as a debt-like instrument, amortized under the effective interest rate method over the life of the related expected royalty stream. The liabilities related to the sale of royalties and the debt amortization are based on our current estimates of royalties expected to be paid over the life of the arrangement. To the extent total royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall. We will periodically assess the expected royalty payments using projections from external sources. To the extent our estimates of royalty payments are greater or less than previous estimates or the estimated timing of such payments is materially different than previous estimates, we will adjust the effective interest rate and recognize revenue if four basic criteria have been met: (1) there is persuasive evidence of an arrangement, (2) delivery has occurred or services have been rendered, (3) the fee is fixed or determinable, and (4) collectability is reasonably assured. Where the revenue recognition criteriarelated non-cash interest expense on a retrospective basis. We are not ~~met, we defer~~obligated to repay the ~~recognition of revenue by recording deferred revenue until such time as all criteria are met.~~

~~Aptevo recognized a tax impact due~~proceeds received under the Royalty Purchase Agreement with HCR. Due to the restatement of our tax liability (see Note 10 – Restatement), as well as the exception to the Intraperiod Tax Allocation rules in accordance with ASC 740-20-45-7. The exception required that all items (including discontinued operations) be considered in determining the amountnature of the ~~tax benefit resulting~~transaction, which includes a cap on HCR’s return from royalties, constituting continuing involvement under the Collaboration and License Agreement originally between Trubion and Wyeth, we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement.

On March 30, 2021, we amended our Credit Agreement with MidCap Financial and used $10 million of the proceeds received from the ~~loss in continuing operations.~~

~~In May 2014,~~Royalty Purchase Agreement to pay down the ~~Financial Accounting Standards Board (FASB) issued Accounting Standard Update No. 2014-09, Revenue~~outstanding principal under the Credit Agreement from ~~Contracts with Customers (Topic 606)~~$25 million to $15 million. The amended Credit Agreement was accounted for under ASC 470-50, Debt Modifications and Extinguishments as a debtmodification, rather than an ~~updated standard~~extinguishment, based on revenue recognition. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported by companies while also improving comparability in the financial statements of companies reporting using International Financial Reporting Standards or GAAP. The main purposea comparison of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which a company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively and improve guidance for multiple-element arrangements. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferralpresent value of the ~~Effective Date,~~cash flows under the terms of the debt immediately before and after the amendment, which ~~deferred~~resulted in a change of less than 10%. Unamortized issuance costs as of the date of modification will be amortized to interest expense using the effective ~~date of~~interest method over the new revenue standard for periods beginning after December 15, 2016 to December 15, 2017, with early adoption permitted but not earlier than the original effective date. Accordingly, the updated standard is effective for Aptevorepayment term.

Our other significant accounting policies were reported in the first quarter of fiscal 2018. Aptevo has assembled a cross functional team to identify the population of contracts with customers and evaluate them under the provisions of ASU No. 2014-09. Aptevo intends to adopt the new standardour Annual Report on a modified retrospective basis. Under this implementation method, Aptevo will recognize the cumulative effect of initially applying the new guidance as an adjustment to the opening retained earnings balance for the annual reporting period of initial application. While Aptevo is continuing its assessment of all the potential impacts of the new standard, it does not expect the implementation of the standard to have a material impact on Aptevo’s consolidated financial position, results of operations or cash flow.

In August 2014, the FASB issued ASU No.2014-15 Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under the new guidance, management is required to assess an entity’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. The provisions of this standard are effective for annual periods ending after December 31, 2016, and for annual and interim periods thereafter. Aptevo adopted this guidanceForm 10-K for the year ended December 31, ~~2016 and management believes~~2021 that ~~Aptevo’s existing cash, cash equivalents and short-term investments will be sufficient to fund its operations for twelve months~~was filed with the SEC on March 24, 2022. Our other significant accounting policies have not changed materially from the ~~date of this filing. Aptevo is required to reassess this position on a quarterly basis and future facts and circumstances may yield a different conclusion.~~

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases (with the exception of short term leases) at the commencement date. Lessor accounting under ASU 2016-02 is largely unchanged. ASU 2016-02 is effective for annual and interim periods beginning on or after December 15, 2018 and early adoption is permitted. Under ASU 2016-02, lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Lessees and lessors may not apply a full retrospective transition approach. The ASU will be effective for the Company starting on January 1, 2019. Aptevo is continuing to evaluate the impact of the application of this ASU on our consolidated financial statements and disclosures. We expect to recognize right of use assets and lease liabilities.

In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including the financial statement presentation of excess tax benefits and deficiencies, classification of awards as either equity or liabilities, accounting for forfeitures and classification on the statement of cash flows. Aptevo adopted this standard effective January 1, 2017. Upon adoption of the standard, excess tax benefits and deficiencies resulting from stock-based compensation awards vesting and exercises are now recognized as discrete items in the statement of operations. Aptevo has elected to maintain its current forfeitures policy and will continue to include an estimate of forfeitures when recognizing stock-based compensation expense. Additionally, cash paid by Aptevo when directly withholding shares for tax withholding purposes will continue to be classified as a financing activity in the condensed consolidated statement of cash flows as required by the standard. The adoption of this standard did not have a material impact on Aptevo’s consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which clarifies the classification and presentation of eight specific cash flow issues in the statement of cash flows. This standard is effective beginning January 1, 2018, with early adoption permitted. The new standard requires a retrospective transition. Aptevo is aware the adoption of this standard will have an impact for restricted cash, and evaluating further impacts on its consolidated financial statements.policies previously reported.

~~On August 31, 2017, Aptevo entered into a sale agreement with Saol International Limited (Saol) whereby Aptevo agreed to sell its~~ ~~Hyperimmune Business~~. The ~~sale was completed on September 28, 2017.~~

~~At the closing of~~accompanying financial statements include discontinued operations from two separate transactions: the sale ~~Saol paid an amount equal to $65.0 million, including $3.3 million~~of our hyperimmune business in 2017, from which ~~was deposited~~we received a payment in an escrow account for the purposes of satisfying any indemnification claims brought by Saol pursuant to the LLC sale agreement.

On July 20, 2017, our wholly owned subsidiary Aptevo Research and Development LLC (Aptevo R&D), entered into a collaboration and option agreement ~~(Collaboration~~(the Collaboration Agreement) with Alligator Bioscience AB (Alligator), pursuant to which Aptevo and Alligator will collaboratively develop ALG.APV-527, a lead bispecific antibody candidate simultaneously targeting 4-1BB (CD137), a member of the TNFR superfamily of a costimulatory receptor found on activated ~~T cells,~~T-cells, and 5T4, a tumor antigen widely overexpressed in a number of different types of cancer. ~~This product candidate~~

We assessed the arrangement in accordance with ASC 606 and concluded that the contract counterparty, Alligator, is ~~built on our novel ADAPTIR platform, which~~not a customer. As such the arrangement is ~~designed to expand on~~not in the ~~utility~~scope of ASC 606 and ~~effectiveness of therapeutic antibodies. Under this Collaboration Agreement, Alligator also granted to Aptevo~~is instead treated as a ~~time-limited option to enter into a second~~collaborative agreement with Alligator for the joint development of a separate bispecific antibody candidate simultaneously targeting 4-1BB (CD137) and 5T4 a tumor antigen that Aptevo R&D and Alligator will collaboratively select.

under ASC 808 – Collaborative Arrangements (ASC 808). In accordance with ~~the terms of~~ASC 808, we concluded that because the Collaboration Agreement is a cost sharing agreement, there is no revenue.

For the ~~parties intend to develop the lead bispecific antibody candidate targeting 4-1BB (CD137)~~three months ended March 31, 2022 and ~~5T4 through the completion of Phase II clinical trials~~ March 31, 2021, we recorded approximately $0.2 million and $0.1 million in ~~accordance with an agreed upon~~our research and development plan and budget. Subject to certain exceptions for Aptevo’s manufacturing and platform technologies, the parties will jointly own intellectual property generated in the performance of the development activities under the Collaboration Agreement.

Following the completion of the anticipated development activities under the Collaboration Agreement, the parties intend to seek a third-party commercialization partner for this product candidate, or, in certain circumstances, may elect to enter into a second agreement granting rights to either Aptevo R&D or Alligator to allow such party to continue the development and commercialization of this product candidate. Under the terms of this Collaboration Agreement, the parties intend to share revenue received from a third-party commercialization partner equally, or, if the development costs are not equally shared under this Collaboration Agreement, in proportion to the development costs borne by each party.

The Collaboration Agreement also contains several points in development at which either party may elect to “opt-out” (i.e., terminate without cause) and, following a termination notice period, cease paying development costs for this product candidate, which would be borne fully by the continuing party. Following an opt-out by a party, the continuing party will be granted exclusive rights to continue the development and commercialization of the product candidate, subject to a requirement to pay a percentage of revenue received from any future commercialization partner for this product, or, if the continuing party elects to self-commercialize, tiered royalties on the net sales of the product by the continuing party ranging from the low to mid-single digits, based on the point in development at which the ‘opt-out’ occurs. The parties have also agreed on certain technical criteria or ‘stage gates’expense related to the ~~development of this product candidate that, if not met, will cause an automatic termination and wind-down of this~~ Collaboration Agreement ~~and the activities thereunder, provided that the parties do not agree to continue.~~, respectively.

~~The Collaboration Agreement contains industry standard termination rights, including for material breach following a specified cure period, and in the case of a party’s insolvency.~~

In August 2014, Aptevo entered into a collaboration agreement with MorphoSys AG (MorphoSys Agreement) for the joint development of MOR209/ES414, a targeted immunotherapeutics protein, which activates host T-cell immunity specifically against cancer cells expressing prostate specific membrane antigen, an antigen commonly overexpressed on prostate cancer cells. Effective August 31, 2017, MorphoSys terminated the MorphoSys Agreement. As a result of the termination, Aptevo has no ongoing obligation related to this agreement and therefore recognized the total remaining deferred revenue balance of $3.7 million as Collaborations revenue in the third quarter of 2017.

The Company’s estimates of fair value for financial assets and financial liabilities are based on the framework established in the fair value accounting guidance. The framework is based on the inputs used in valuation, it gives the highest priority to quoted prices in active markets and requires that observable inputs be used in the valuations when available. The disclosure of fair value estimates in the fair value accounting guidance hierarchy is based on whether the significant inputs into the valuation are observable. In determining the level of the hierarchy in which the estimate is disclosed, the highest priority is given to unadjusted quoted prices in active markets and the lowest priority to unobservable inputs that reflect the Company’s significant market assumptions. The level in the fair value hierarchy within which the fair value measurement is reported is based on the lowest level input that is significant to the measurement in its entirety. The three levels of the hierarchy are as follows:

Level 1— Quoted prices in active markets for identical assets and liabilities;

Level 2— Inputs other than quoted prices in active markets that are either directly or indirectly observable; and

Level 3— Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

~~The Company’s financial assets measured at fair value consisted of the following as of September 30, 2017~~At March 31, 2022 and December 31, ~~2016:~~

⁽¹⁾~~The 2016 inventory balances have been updated to reflect the impact of the sale of the~~ ~~Hyperimmune Business. See Note 2 -Sale of Hyperimmune Business~~

Due to the sale of Aptevo’s Hyperimmune Business, the remaining inventory is solely related to IXINITY. CMC ICOS Biologics, Inc. (CMC) is the sole manufacturer of the bulk drug substance for our IXINITY product. During 2015, we ordered nine manufacturing lots of bulk drug substance from CMC and only one of those lots was successfully manufactured and released in 2015. On October 4, 2016, we provided a Notice of Interruption in Manufacturing, or Notice, to the U.S. Food and Drug Administration (FDA), notifying the FDA of a potential interruption in the supply of IXINITY due to the ongoing manufacturing challenges with the manufacturer of the bulk drug substance. On March 15, 2017, we announced the successful manufacture of a new bulk drug substance batch of IXINITY, providing new supply of IXINITY for the commercial market in May 2017.

On June 17, 2017, the Company and CMC entered into a new non-exclusive Amended and Restated Commercial Supply, or Restated Supply Agreement, for the commercial development and manufacture of IXINITY. Pursuant to the terms of the Restated Supply Agreement, CMC agreed to manufacture IXINITY in the quantity of batches provided to CMC on a twenty-four month rolling forecast. Beginning 2018, the minimum and maximum batches will be four and ten, respectively, in a calendar year. Multiple batches ordered in succession with no changeover to another product between batches, or a campaign, shall receive an incremental discounted price.

In accordance with the Restated Supply Agreement, a $7.0 million reserve held by CMC will be applied to, at a minimum, the next seven batches manufactured through the end of 2017 as a price concession. As a result, at least the next seven batches will have reduced raw materials or other related CMC costs associated with the inventory. Aptevo will also see an impact on the Company’s statement of operations due to a lower costs of goods sold associated with this inventory, which will also result in higher gross margins as sales are recognized. Any portion of the $7.0 million reserve held by CMC that remains unutilized as of December 25, 2017 shall be paid to the Company in cash on or before December 31, 2017. As of September 30, 2017, $2.6 million has been applied against the reserve and recorded as a reduced cost to inventory. The Restated Supply Agreement has a five-year term renewable with twenty-four months’ prior notice before the expiry of the term for successive two-year terms.

On August ~~4, 2016,~~5, 2020, we entered into a ~~$35.0 million~~ Credit and Security Agreement (the Credit Agreement), with MidCap ~~Financial Trust.~~Financial. The Credit Agreement ~~prior to the amendments described below,~~ provided us with up to ~~$35.0~~$25.0 million of available borrowing capacity ~~available (subject to certain conditions) in two tranches of $20.0 million and $15.0 million. Amounts drawn~~ under ~~the Credit Agreement bear interest at~~ a ~~rate of LIBOR plus 7.60% per annum.~~ term loan facility. The ~~first tranche of $20.0~~full $25.0 million was ~~funded~~drawn on the closing date of the Credit Agreement. The term loan facility has a 48 month term, is interest-only for the first 18 months, with straight-line amortization for the ~~second tranche of $15.0 million to become available (subject to certain conditions) following the date Aptevo~~remaining 30 months and its subsidiaries: (1) achieve net commercial product revenue of $40.0 million on a trailing twelve-month basis, and (2) receive an additional $20.0 million in cash from Emergent. Emergent made this payment on January 13, 2017.We paid debt issuance costs of $1.9 million of which $1.5 million remains unamortized at September 30, 2017. The loan repayment included interest (no principal) through August 2018 and was set to transition to principal and interest as of August 2018 and to be repaid in full on February 1, 2021 (54 months). Amounts drawn under the Credit Agreement bearbears interest at a rate of one month LIBOR plus ~~7.60%~~6.25% per ~~annum.~~annum, subject to a 1.50% LIBOR floor and a 2.50% LIBOR cap. Certain assets of the Company are pledged as collateral under the terms of the Credit Agreement. The United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, phased out one-week and two-month US Dollar LIBOR settings on December 31, 2021. All other US Dollar LIBOR settings, including the overnight, one-month, three-month, six-month and twelve-month, will be phased out on June 30, 2023. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2023. Our Credit Agreement with MidCap Financial currently references one-month LIBOR and also provides that we may amend the Credit Agreement to reflect an alternative rate of interest upon the phase out of LIBOR.

On November 6, 2020, Kevin Tang and his related entities filed a statement on Schedule 13D to report the purchase of 1,760,000 shares of the Company’s common stock, which at the time represented approximately 54% of the Company’s issued and outstanding shares of the Company’s common stock. This acquisition of voting stock triggered a change in control, resulting in an Event of Default under Section 10.1(a)(ii) of the Credit Agreement. On November 10, 2020, the Company obtained a waiver from MidCap Financial pursuant to which, among other things, MidCap Financial waived such Event of Default and MidCap Financial and the Company agreed that an immediate event of default under the Credit Agreement will be deemed to have occurred in the event that (a) a majority of the seats on the Company’s board of directors are occupied by persons who were neither (i) nominated by the Company’s board of directors nor (ii) appointed by the directors so nominated, and (b) Tang has appointed the majority of the Company’s board of directors. No other events of default have occurred with respect to the Credit Agreement.

On March 30, 2021, we amended our Credit Agreement with MidCap Financial and used $10.0 million of the proceeds received from the Royalty Purchase Agreement to pay down the outstanding principal under the Credit Agreement from $25.0 million to $15.0 million. $10.0 million of the remaining $15.0 million principal balance was paid on March 29, 2022. Beginning March 1, 2022, monthly repayment of the remaining $5.0 million of principal commenced and will continue for the final 30 months of the loan term. The term loan facility includes additional payment provisions if milestones related to IXINITY under the LLC Purchase Agreement with Medexusor royalties related to RUXIENCE under the Royalty Purchase Agreement with HCRare sold during the term of the loan. If the Company sells the IXINITY deferred payment stream and milestones prior to full repayment of this $5.0 million principal amount, under the agreement with MidCap Financial, we will be required to use the proceeds from the sale to pay down the outstanding loan principal balance. MidCap Financial also released its security interest in the RUXIENCE royalty payments. A fee of $0.6 million was paid by the Company to MidCap Financial in connection with the amendment in lieu of the formula-based fee previously required.

The amended Credit Agreement ~~contained financial covenants that require us~~was accounted for as a debt modification, rather than an extinguishment, based on a comparison of the present value of the cash flows under the terms of the debt immediately before and ~~our subsidiaries~~after the amendment, which resulted in a change of less than 10%. Unamortized issuance costs as of the date of modification will be amortized to ~~maintain increasing minimum net commercial product revenue for each twelve-month period ending on~~interest expense using the ~~last day of each calendar quarter, commencing with~~effective interest method over the ~~twelve-month period ending September 30, 2016.~~ repayment term.

As of March 31, ~~2017,~~2022, we classified $2.0 million of the ~~Company’s~~remaining $4.8 million principal of the amended Credit Agreement to current portion of long-term debt on the unaudited condensed consolidated balance sheet.

This facility is subject to a subjective acceleration clause that could be invoked by MidCap Financial upon the occurrence of any event MidCap Financial deems to have a material adverse effect on our ability to repay the lender.

In March 2021, we entered into and closed the Royalty Purchase Agreement with HCRpursuant to which we sold to HCR the right to receive royalty payments made by Pfizer in respect of global net ~~minimum~~sales of RUXIENCE. Under the terms of the agreement, we received $35.0 million at closing and we are eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022 and 2023. The Company received the 2021 milestone payments in the collective amount of $10.0 million on March 8, 2022. The proceeds from these milestone payments, net of transaction costs, were recorded as an additional liability related to the sale of royalties on the consolidated balance sheet as of March 31, 2022. The Company is eligible to receive additional payments in aggregate of up to $22.5 million based on achievement of sales milestones in 2022 and 2023. The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the amount paid at closing plus Milestone Amounts to the extent paid by HCR to the Company, Aptevo will be entitled to receive 50% of royalty interest payments thereafter.

The proceeds received from HCR of $35.0 million were recorded as a liability, net of transaction costs of $1.1 million, which will be amortized over the life of the arrangement using the effective interest method. In order to determine the amortization of the liability, we are required to estimate the total amount of royalty payments to be received by HCR over the life of the arrangement. The total amount of royalty payments received by HCR under the Royalty Purchase Agreement, less the net proceeds we received of $33.9 million, is recorded as non-cash interest expense over the life of the arrangement using the effective interest method. We retain certain rights unrelated to the royalties under the Definitive Agreement originally between Trubion and Wyeth, with the exception of the cash flows of the RUXIENCE royalty payments and related rights purchased by HCR. Due to the nature of the transaction, which includes a cap on HCR’s return from royalties, constituting continuing involvement under the Collaboration and License Agreement originally between Trubion and Wyeth, we continue to recognize royalty revenue ~~did~~on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. To the extent total royalties collected are an amount less than the liability, the Company is not ~~meet~~obligated to fund any such shortfall.

We estimate the ~~required minimum for~~effective interest rate used to record non-cash interest expense under the ~~twelve~~Royalty Purchase Agreement based on the estimate of royalty payments to be received by HCR. As of March 31, 2022, the estimated effective interest rate under the agreement was 23.0%. Over the life of the arrangement, the actual effective interest rate will be affected by the amount and timing of the royalty payments received by HCR and changes in our forecasted royalties. Periodically, we will reassess our estimate of total royalty payments to be received by HCR, and retrospectively adjust the effective interest rate and amortization of the liability as necessary.

The following table presents the changes in the liability in the quarter related to the sale of royalties under the Royalty Purchase Agreement with HCR (in thousands):

For the three months ended March 31, ~~2017.~~2022 and March 31, 2021, we recorded $0.2 million and $0.2 million, respectively, related to variable expenses.

As of March 31, 2022, we have operating leases for 1 piece of lab equipment and 4 copiers in our Seattle, Washington headquarters. The future expense for these leases will be straight-line and will include any variable expenses that arise.

As of March 31, 2022, we had 1 equipment lease classified as a ~~result, on May 11, 2017, we and MidCap Financial Trust entered into an amendment~~financing lease as the lease transferred ownership of the underlying asset to us at the ~~Credit Agreement to, among other things, waive~~end of the ~~existing event of default and revise~~lease term in 2020. The lease has no remaining expense obligation. There were 0 financing lease payments in the ~~financial covenants pertaining to the minimum required commercial product revenue for the twelve~~three months ended March 31, ~~2017 and future rolling twelve month periods. As a result~~2022.

The long-term portion of the ~~amendment,~~lease liabilities included in the ~~Company was in compliance with the modified minimum net revenue covenant for the three and six months ended June 30, 2017. As such,~~ amounts ~~owed under the Credit Facility are classified based on their contractual maturities.~~

This first amendment revised the provisions of the Credit Agreement to: (1) extend the time period through which the Company could draw the second tranche from August 2017 to March 2018, (2) increase the exit fee of 5.75% of the aggregate principal amount under the Credit Agreement for repayment or prepayment other than scheduled amortization paymentsabove is $1.1 million and the ~~final payment~~remainder of ~~principal to 6.75%~~our lease liabilities are included in other current liabilities on our unaudited condensed consolidated balance sheets.

As of March 31, 2022, the weighted average remaining lease term and ~~(3) permit MidCap Financial Trust to obtain an affirmative lien on~~weighted average discount rate for operating leases was 1.08 years and 14.45%. As of March 31, 2021, the ~~intellectual property of the Company, upon the earlier of (i) the Company’s draw down of the second tranche or (ii) the Company’s cash, cash equivalents,~~weighted average remaining lease term and ~~short-term investments balance descend below a minimum cash threshold of $25 million.~~

On September 28, 2017, the Company entered into a second amendment of the Credit Agreement (Amendment No. 2) in order to permit the sale under the LLC purchase agreement described in Note 2 Sale of Hyperimmune Business,weighted average discount rate for operating leases was 2.05 years and ~~to reflect changes in the remaining business as a result of such sale.~~

Pursuant to the Amendment No. 2, the agent and the lenders consented to the LLC purchase agreement and the consummation of the sale transaction, released the agent’s liens on the assets transferred to Venus Bio Therapeutics Sub LLC (Venus) prior to the sale, and agreed that no prepayment of the term loans under the credit agreement would be required as a result the sale.

In addition, as part of the Amendment No. 2, the agent and the lenders agreed that: (i) the commitments of the lenders to make the remaining $15 million tranche of loans under the credit agreement were terminated, (ii) the covenant levels set forth in the minimum net commercial product revenue covenant were revised, (iii) a new covenant was added requiring the Company to maintain a minimum $10.0 million unrestricted cash balance, and (iv) the date on which the term loans begin to amortize will be extended to February 1, 2019 if the Company achieves net commercial product revenues of $16 million for the twelve month period ending June 30, 2018 and maintains such level of net commercial product revenues for each quarter prior to February 1, 2019 thereafter.

Basic net income (loss) per share is calculated by dividing the net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) by the weighted average number of common share equivalents outstanding for the period using the as-if converted method. For the purpose of this calculation, warrants, stock options and restricted stock units (RSUs) are only included in the calculation of diluted net income (loss) per share when their effect is dilutive.

~~Prior~~We utilize the control number concept in the computation of diluted earnings per share to ~~the spin-off, Aptevo did not operate as a separate entity and as a result did not have any~~determine whether potential common stock ~~outstanding~~instruments are dilutive. The control number used is loss from continuing operations or income from discontinued operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other ~~than 1,000 shares held by Emergent. The~~categories of income or loss, regardless of their anti-dilutive effect on such categories. Therefore, no dilutive effect has been recognized in the calculation of ~~basic and diluted net loss~~income from discontinued operations per ~~share assumes that the 20,229,849 ordinary shares issued to Aptevo stockholders in connection with the spin-off were outstanding from the beginning of the periods presented.~~share.

On December 14, 2020, we entered into an Equity Distribution Agreement (the Equity Distribution Agreement) with Piper Sandler. The Equity Distribution Agreement provides that, upon the terms and subject to the conditions set forth therein, we may issue and sell through Piper Sandler, acting as sales agent, shares of our common stock, $0.001 par value per share having an aggregate offering price of up to $50.0 million. This offering supersedes and replaces the program we commenced in December 2017. We have no obligation to sell any such shares under the Equity Distribution Agreement. The sale of such shares of common stock by Piper Sandler will be effected pursuant to a Registration Statement on Form S-3 which we filed on December 14, 2020. We did 0t issue any shares under the Equity Distribution Agreement in the three months ended March 31, 2022 and 2021.

On December 20, 2018, we entered into a Purchase Agreement and a Registration Rights Agreement, with Lincoln Park (the Purchase Agreement), both of which expired in March 2022. Pursuant to the Purchase Agreement, Lincoln Park has committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing on February 13, 2019, the date the registration statement covering the resale of the shares was declared effective by the SEC. Under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase shares of our common stock provided that Lincoln Park’s maximum commitment on any single day does not exceed $2.0 million. The purchase price per share will be based off of prevailing market prices of our common stock immediately preceding the time of sale; provided, however, that we cannot direct any such purchase if the prevailing market price is less than $1.00.

On February 16, 2022, the Company entered into a new Purchase Agreement and a Registration Rights Agreement with Lincoln Park. Under the new Purchase Agreement, Lincoln Park committed to purchase up to $35.0 million of our common stock over a 36-month period commencing after the satisfaction of certain conditions, which are within our control, as set forth in the Purchase Agreement. The purchase price per share will be based on prevailing market price; provided, however, that the prevailing market price is not below $1.00. The Company agreed to issue 99,276 shares of our common stock to Lincoln Park for 0 cash consideration as an initial fee for its commitment to purchase shares of our common stock under the Purchase Agreement. The Company did 0t issue any shares of common stock for cash consideration to Lincoln Park under the Purchase Agreement in the three months ended March 31, 2022.

On ~~August~~November 8, 2020, our Board of Directors (Board) approved and adopted a Rights Agreement, dated as of November 8, 2020, by and between the Company and Broadridge Corporate Issuer Solutions, Inc., as rights agent, pursuant to which the Board declared a dividend of 1 ~~2016, in connection with~~preferred share purchase right (each, a Right) for each outstanding share of the ~~spin-off~~Company’s common stock held by stockholders as of the close of business on November 23, 2020. When exercisable, each right initially would represent the right to purchase from the Company one one-thousandth of a share of a newly-designated series of preferred stock, Series A Junior Participating Preferred Stock, par value $0.001 per share, of the Company, ~~from Emergent, we issued 20.2 million shares~~at an exercise price of $400.00 per one one-thousandth of a Series A Junior Participating Preferred Share, subject to Emergent stockholders and recorded a contribution from Emergent of $71.2 million. The transactions recorded in 2016 included a one-time payment of $45.0 million, and a working capital reimbursement for outstanding payments of $1.4 million, a noncash transfer of an intangible asset of $0.7 million, and a net transfer of cash from Emergent of $24.2 million. In addition,adjustment. Subject to various exceptions, the Rights become exercisable in the ~~first quarter~~event any person (excluding certain exempted or grandfathered persons) becomes the beneficial owner of ~~2017 we received $20.0 million as payment for a promissory note issued at the time~~ten percent (10%) or more of the ~~spin-off.~~Company’s common stock without the approval of the Board. The Rights Agreement was amended on November 4, 2021 to extend the expiration date of such agreement from November 8, 2021 to November 5, 2022.

The Company had no stock-based compensation plans of its own prior to the spin-off from Emergent; however certain Aptevo employees participated in Emergent’s stock-based compensation plans (Emergent Plans), which provided for the grants of stock options and restricted stock units (RSUs). The expense associated with Aptevo employees who participated in the Emergent Plans was allocated to the Company in the accompanying Statements of Operations for the associated periods prior to the spin off.

In connection with the spin-off ~~the Company~~from Emergent BioSolutions, Inc. (Emergent) in August 2016, we adopted the Converted Equity Awards Incentive Plan (Converted Plan) and outstanding equity awards of Emergent held by Aptevo employees were converted into or replaced with equity awards of Aptevo (Conversion Awards) under the Converted Plan and were adjusted to maintain the economic value before and after the distribution date using the relative fair market value of the Emergent and Aptevo common stock based on the closing prices as of August 1, 2016. There was no significant incremental stock-based compensation expense recorded as a result of the equity award conversion.. A total of ~~1.3~~0.1 million shares of Aptevo common stock have been authorized for issuance under the Converted Plan. Options issued as Conversion Awards were priced according to the Converted Plan. RSUs issued as part of the Converted Plan provide for the issuance of a share of the Company’s stock at no cost to the holder.

On August 1, 2016, the Company adopted the 2016 Stock Incentive Plan ~~(2016~~(the 2016 SIP). A total of ~~3.1~~0.2 million shares of Aptevo common stock have been authorized for issuance under the 2016 SIP in the form of ~~incentive~~equity stock options.

Stock options under the 2016 SIP generally vest pro rata over a three-year period and terminate ten years from the grant date, though the specific terms of each grant are determined individually. The Company’s executive officers and certain other employees may be awarded options with different vesting criteria, and options granted to non-employee directors also vest over a three-year period. Option exercise prices for new options granted by the Company equal the closing price of the Company’s common stock on the NASDAQ Global Market on the date of grant.

RSUs issued under the 2016 SIP provide for the issuance of a share of the Company’s common stock at no cost to the holder. RSUs granted to employees under the 2016 SIP generally provide for time-based vesting over an eighteen-month to three-year period, although certain employees may be awarded RSUs with different time-based vesting criteria. Prior to vesting, RSUs granted under the 2016 SIP do not have dividend equivalent rights, do not have voting rights and the shares underlying the RSUs are not considered issued or outstanding.

The equity compensation awards granted by the Company generally vest only if the employee is employed by the Company (or in the case of directors, the director continues to serve on the Board) on the vesting date.

On May 31, 2017, at the 2017 Annual Meeting of Stockholders (Annual Meeting), the Company’s stockholders approved the amendment and restatement of the Company’s 2016 SIP (Restated 2016 Plan) to, among other things, increase the number of authorized shares issuable by ~~1.3~~0.1 million shares of Aptevo common stock. The Restated 2016 Plan was previously approved, subject to stockholder approval, by the Board of Directors of the Company.

On June 1, 2018, at the 2018 Annual Meeting of the Stockholders, the Company’s stockholders approved a new 2018 Stock Incentive Plan (2018 SIP), which replaced the Restated 2016 Plan on a go-forward basis. All stock options, RSUs or other equity awards granted subsequent to June 1, 2018 have been and will be issued out of the 2018 SIP, which has 0.3 million shares of Aptevo common stock authorized for issuance. The ~~Restated 2016~~2018 Plan became effective immediately upon stockholder approval at the 2018 Annual ~~Meeting.~~Meeting of the Stockholders. Any shares subject to outstanding stock awards granted under the 2016 SIP that (a) expire or terminate for any reason prior to exercise or settlement; (b) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company; or (c) otherwise would have returned to the 2016 SIP for future grant pursuant to the terms of the 2016 Plan (such shares, the “Returning Shares”) will immediately be added to the share reserve under the 2018 SIP as and when such shares become Returning Shares, up to a maximum of 0.3 million shares. As of March 31, 2022, there are less than 0.1 million shares available to be granted under the 2018 SIP.

Stock options and RSUs under the 2018 SIP generally vest pro rata over a three-year period. Stock options terminate ten years from the grant date, though the specific terms of each grant are determined individually. The Company’s executive officers and certain other employees may be awarded options and/or RSUs with different vesting criteria, and awards granted to non-employee directors also vest over a three-year period. Option exercise and RSU grant prices for new awards granted by the Company equal the closing price of the Company’s common stock on the Nasdaq Capital Market on the date of grant.

Stock-based compensation expense includes amortization of stock options and RSUs granted to employees and non-employees and has been reported in our ~~Condensed Consolidated Statements~~unaudited condensed consolidated statements of ~~Operations~~operations as follows:

The Company accounts for stock-based compensation by measuring the cost of employee services received in exchange for all equity awards granted based on the fair value of the award as of the grant ~~date, recognizing~~date. The Company recognizes the compensation expense ~~for that fair value, reduced for an estimate of forfeitures,~~

over the vesting period.All assumptions used to calculate the grant date fair value of nonemployee options are generally consistent with the assumptions used for options granted to employees. In the event the Company terminates any of its consulting agreements, the unvested options underlying the agreements would also be cancelled.

Aptevo utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted. Set forth below are the assumptions used in valuing the stock options granted:

Management has applied an estimated forfeiture rate of ~~10%.~~29% for the three months ended March 31, 2022 and 26% for the three months ended March 31, 2021. Expected volatility increased as our stock price fluctuated from a low of $4.48 to a high of $6.96 for the three months ended March 31, 2022, compared to a low of $27.86 to a high of $40.59 for the three months ended March 31, 2021.

The fair value of each RSU has been determined to be the closing trading price of the Company’s common ~~shares~~stock on the date of grant as quoted ~~in NASDAQ Global~~on the Nasdaq Capital Market.

~~Our December 31, 2015 financial statements include $41.8 million~~In March 2019, as part of ~~intangible assets~~a public offering, we issued warrants to purchase up to 1,725,000 shares of our common stock, 1,571,429 of which ~~resulted from the acquisition~~have an exercise price of ~~in process research~~$18.20 per share and ~~development (IPR&D) programs related to TRU-016,~~have a ~~novel CD37-directed therapy for B-cell malignancies, such as chronic lymphocytic leukemia~~five-year life, and ~~non-Hodgkin’s lymphoma.

For the three months ended March 31, 2022, the Company ~~in August 2016,~~did not have any of its warrants exercised. For the Company conducted an internal review of all deferred tax assets and liabilities acquired and it was determined that a deferred tax liability should have been recorded associated with the difference between the book basis and the tax basis of the asset as a part of the acquisition in 2010. The error has no effect on the net assets distributed in the spin-off.

The Company has restated its statements of operations for the quarterly and nine month periods ended September 30, 2016. The restatement resulted in the recognition of a $15.3 million benefit from income taxes equal to the amount of the deferred tax liability recorded associated with the TRU-016 IPR&D asset when the $41.8 million was impaired. The restatement also resulted in an increase in the impairment expense recognized in the third quarter of 2016 due to the impairment of all goodwill, by the amount that goodwill would have been increased. These two restated captions on the statements of operations have the effect of offsetting each other, resulting in no impact to net loss for the quarter and ninethree months ended ~~September 30, 2016. The restatement adjustment did not impact the consolidated statement of operations for any periods prior to the third quarter of 2016.~~

The impact of the restatement on the Company’s consolidated statements of operations, including the impact of discontinued operations, is reflected and quantified for interim periods affected, as applicable, in the below tables.

~~The following table sets forth our unaudited quarterly consolidated statement of operations data for the three and nine months ended September 30, 2016:~~

⁽¹⁾ ~~These amounts reflect a benefit from income taxes after giving effect to the goodwill and deferred tax liability restatement discussed above. The impairment~~March 31, 2021, certain holders of the Company’s ~~IPR&D~~warrants exercised warrants with strike price of $18.20 per share, resulting in the ~~quarter ended September 30, 2016 resulted in a benefit from income taxes~~issuance of ~~$15.3 million related~~approximately 27,828 shares of the Company’s common stock and aggregate proceeds to the ~~reversal~~Company of the associated deferred tax liability in that quarter. The Company’s interim financial statements included in Form 10-Q for the quarter ended September 30, 2016 did not reflect this benefit from income taxes or the increase in impairmentapproximately $0.5 million. As of ~~goodwill.~~

March 31, 2022 and 2021, there were warrants to purchase 350,589 and 376,866 shares of common stock outstanding, respectively.

This MD&A contains forward-looking statements that are ~~discussed in Note 10- Restatement~~subject to risks and uncertainties, such as those set forth in the ~~accompanying financial~~sections of this Quarterly Report on Form 10-Q captioned “Cautionary Note Regarding Forward-Looking Statements,” “Risk Factors” and elsewhere. As a result, our actual results may differ materially from those anticipated in these forward-looking statements.

We are a clinical-stage, research and development biotechnology company focused on developing novel ~~oncology (cancer)~~immunotherapeutic candidates for the treatment of different forms of cancer. We have developed two versatile and ~~hematology (blood disease) therapeutics to meaningfully improve patients’ lives.~~enabling platform technologies for rational design of precision immune modulatory drugs. Our ~~core~~lead clinical candidate, APVO436, and preclinical candidates, ALG.APV-527 and APVO603, were developed using our ADAPTIR™ modular protein technology platform. Our preclinical candidate, APVO442, was developed using our ADAPTIR-FLEX™ modular protein technology platform. Currently, APVO436 is ~~the ADAPTIR™ (modular protein technology) platform. We currently have one revenue-generating product~~being evaluated in an open-label, multi-center, multi-cohort Phase 1b expansion trial in the ~~areas~~U.S.

The versatile and robust ADAPTIR and ADAPTIR-FLEX platforms are designed to generate monospecific, bispecific, and multi-specific antibody candidates that are capable of ~~hematology,~~enhancing the human immune system against cancer cells. ADAPTIR and ADAPTIR-FLEX are both modular platforms, which gives us the flexibility to generate immunotherapeutic candidates with a variety of mechanisms of action. This flexibility in design allows us to potentially generate novel therapeutic candidates that may provide the foundation for the establishment of effective strategies against difficult to treat, as well as ~~various investigational stage~~advanced forms of cancer. We have successfully designed and constructed numerous investigational-stage prototype product candidates based on our ADAPTIR platform. The ADAPTIR platform technology is designed to generate monospecific and bispecific immunotherapeutic proteins that specifically bind to one or more targets, for example, bispecific therapeutic molecules, which may have structural and functional advantages over monoclonal antibodies. The structural differences of ADAPTIR molecules over monoclonal antibodies allow for the development of ADAPTIR immunotherapeutics that are designed to engage immune effector cells and disease targets in ~~immuno-oncology~~a novel manner to produce unique signaling responses and ~~autoimmune~~ultimately kill tumors or modulate the immune system to kill tumors.

We are skilled at candidate generation, validation, and ~~inflammatory diseases.~~subsequent preclinical and clinical development using the ADAPTIR platform and have added the ADAPTIR-FLEX platform to generate multi-specific candidates or other candidates to our platform capabilities. We have developed preclinical candidate based on the ADAPTIR-FLEX platform which is advancing in our pipeline. We are developing our ADAPTIR and ADAPTIR-FLEX molecules by way of our protein engineering, preclinical development, process development, and clinical development capabilities.

~~In August 2015, Emergent BioSolutions Inc.~~Through the date of this filing, Aptevo has reported that two patients in its Phase 1b expansion trial achieved substantial blast count reduction and clinical benefit and were able to proceed to allogeneic stem cell transplant:

On March 8, 2022, the Company received a $10 million milestone payment related to 2021 sales of RUXIENCE under the terms of the Royalty Purchase Agreement with HCR. The proceeds were used to pay down our MidCap Financial term loan to $5 million, further strengthening the Company’s balance sheet.

On April 1, 2022, the Company received a letter from The Nasdaq Stock Market LLC (“Nasdaq”) indicating that it is not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires companies listed on The Nasdaq Capital Market to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing. On its annual report for the year ended December 31, 2021, the Company reported stockholders’ equity of $1,216,000, and, as a result, does not currently satisfy Listing Rule 5550(b)(1).

Nasdaq’s letter has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on Nasdaq, subject to the Company’s compliance with the other continued listing requirements. Nasdaq’s letter provides the Company 45 calendar days, or ~~Emergent, announced~~until May 16, 2022, to submit a plan to ~~separate into two~~regain compliance. If the plan is accepted, the Company can be granted up to 180 calendar days from April 1, 2022, to evidence compliance. There can be no assurance that the Company will be able to regain compliance with all applicable continued listing requirements or that its plan will be accepted by the Nasdaq staff. In the event the plan is not accepted by the Nasdaq staff, or in the event the plan is granted but the Company fails to regain compliance within the plan period, the Company would have the right to a hearing before an independent ~~publicly traded companies, one a biotechnology company focused on novel oncology and hematology therapeutics to meaningfully improve patients’ lives~~panel. The hearing request would stay any suspension or delisting action pending the conclusion of the hearing process and the expiration of any additional extension period granted by the panel following the hearing.

The Company intends to take all reasonable measures available to regain compliance under the Nasdaq Listing Rules and remain listed on Nasdaq. The Company is currently evaluating its available options to resolve the deficiency and regain compliance with the Nasdaq minimum stockholders’ equity requirement. The Company intends to submit the compliance plan by the Nasdaq deadline.

Except as otherwise stated below, the following discussions of our results of operations reflect the results of our continuing operations, excluding the results related to Aptevo BioTherapeutics LLC (Aptevo BioTherapeutics), which was sold in February 2020 to Medexus and has been separated from continuing operations and reflected as a discontinued operation. See Note 2 – Discontinued Operations to the accompanying financial statements for additional information.

For the three months ended March 31, 2022, royalty revenue increased by $0.7 million, or 29%, to $3.1 million from $2.4 million for March 31, 2021. The payment from Pfizer relates to a Collaboration and License Agreement (Definitive Agreement) acquired by Aptevo as part of our spin-off from Emergent in 2016. The agreement was originally executed by Trubion Pharmaceuticals, which was subsequently acquired by Emergent, and Wyeth, a wholly-own subsidiary of Pfizer. The royalty term runs through January 2027, which is the seventh anniversary of the first commercial sale of the CD20 biosimilar. On March 30, 2021, we entered into the Royalty Purchase Agreement pursuant to which we sold to HCR the right to receive royalty payments made by Pfizer in respect of net sales of RUXIENCE. We retain certain rights unrelated to the royalties under the Definitive Agreement originally between Trubion and Wyeth, with the exception of the cash flows of the RUXIENCE royalty payments and related rights purchased by HCR. Due to the nature of the transaction, which includes a cap on HCR’s return from royalties, constituting continuing involvement under the Collaboration and License Agreement originally between Trubion and Wyeth, we continue to recognize royalty revenue on net sales of RUXIENCE and record the royalty payments to HCR as a reduction of the liability when paid. As such payments are made to HCR, the balance of the liability will be effectively repaid over the life of the Royalty Purchase Agreement. To the extent total royalties collected are an amount less than the liability, the Company is not obligated to fund any such shortfall.

We expense research and development costs as incurred. These expenses consist primarily of the costs associated with our research and development activities, including conducting non-clinical studies and clinical trials, fees to professional service providers for analytical testing, consulting costs, independent monitoring or other administration of our clinical trials and obtaining and evaluating data from our clinical trials and non-clinical studies, as well as costs of contract manufacturing services for clinical trial material, and costs of materials used in clinical trials and research and development. Our research and development expenses include:

We expect our research and development spending will be dependent upon such factors as the results from our clinical trials, the availability of reimbursement of research and development spending, the number of product candidates under development, the size, structure and duration of any clinical programs that we may initiate, and the costs associated with manufacturing our product candidates on a ~~global specialty life sciences company focused on providing specialty products~~large-scale basis for ~~civilian~~later stage clinical trials. We may experience interruption of key clinical trial activities, such as patient enrollment and ~~military populations that address intentional~~clinical trial site monitoring, and ~~naturally emerging public health threats. To accomplish this separation, Emergent created~~key non-clinical activities due to the ongoing COVID-19 pandemic. While the majority of our programs are still in the preclinical trial phase, we do not provide a ~~new company, Aptevo Therapeutics Inc., or Aptevo, to be~~breakdown of the ~~parent company~~initial associated expenses as we are often evaluating multiple product candidates simultaneously. Costs are reported in preclinical research and discovery until the program enters the clinic.

Our research and development expenses by program for the ~~development-based biotechnology~~three months ended March 31, 2022 and 2021 are shown in the following table:

For the three months ended March 31, 2022, research and development expenses decreased by $0.5 million, to $4.9 million from $5.4 million for March 31, 2021. The decrease was primarily due to lower spending on preclinical projects and employee costs. The decrease was partially offset by higher spending on our APVO436 clinical trial as we continue to advance that trial and continue to dose patients in our Phase 1b Expansion program.

General and administrative expenses consist primarily of personnel-related costs and professional fees in support of our executive, business ~~focused~~development, finance, accounting, information technology, legal and human resource functions. Other costs include facility costs not otherwise included in research and development expenses.

For the three months ended March 31, 2022 and 2021, general and administrative expenses were $3.9 million.

Other expense, net consists primarily of gains or losses realized on ~~novel oncology, hematology,~~foreign currency revaluation, costs related to debt extinguishment, accrued exit fees on debt, non-cash interest on financing agreements, and ~~autoimmune~~interest on debt. Other expense, net was $2.3 million for the three months ended March 31, 2022 and ~~inflammatory therapeutics.~~$0.8 million for the three months ended March 31, 2021. The increase in other expense, net is primarily related non-cash interest expense for the Royalty Purchase Agreement. The increase was partially offset by lower interest expense for the MidCap Credit Agreement due to principal paydown.

The accompanying unaudited condensed consolidated financial statements include discontinued operations from two separate transactions: the sale of hyperimmune business to Saol International Limited in September 2017, from which we received a payment in 2021 related to the collection of a certain accounts receivable, and the sale of Aptevo BioTherapeutics in 2020.

The following table represents the components attributable to income from discontinued operations in the unaudited condensed consolidated statements of operations (in thousands):

For the three months ended March 31, 2022 we collected $0.2 million in deferred payments from Medexus related to IXINITY sales. For the three months ended March 31, 2021, we collected $0.2 million related to the sale of the hyperimmune business to Saol as a result of the collection of certain accounts receivable and a deferred payment of $0.2 million received from Medexus related IXINITY sales. Pursuant to our LLC Purchase Agreement, the rate for deferred payments will increase from 2% to 5% of net sales no later than June 30, 2022.

The preparation of our unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We ~~were incorporated~~base our estimates on historical experience and on various other factors. Although we believe that our judgments and estimates are appropriate, actual results may differ materially from our estimates and changes in ~~Delaware~~these estimates are recorded when known. An accounting policy is considered critical if it is important to a company’s financial condition and results of operations and if it requires the exercise of significant judgment and the use of estimates on the part of management in its application.

Refer to Note 1 for discussion of our accounting policies, significant judgments, and estimates.

The following table provides information regarding our cash flows for the three months ended March 31, 2022 and 2021:

Net cash used in operating activities of $5.1 million for the three months ended March 31, 2022 was primarily due to our net loss of $7.7 million and changes in working capital accounts. Net cash used in operating activities of $7.5 million for the three months ended March 31, 2021, was primarily due to our net loss of $7.3 million and changes in working capital accounts.

Net cash used in investing activities for the three months ended March 31, 2022 and 2021, was due to purchases of property and equipment. The Company had immaterial purchase of property and equipment for the three months ended March 31, 2022 and $0.2 million purchase of property and equipment for the three months ended March 31, 2021.

Net cash used in financing activities for the three months ended March 31, 2022 was primarily due to the $10.7 million of partial repayments of the MidCap Financial term loan and $3.7 million royalties received by HCR pursuant to our Royalty Purchase Agreement. This was offset by the $10 million milestone received from HCR related to the sale of royalties, net of $0.5 million transaction costs. Net cash provided by financing activities for the three months ended March 31, 2021, was primarily due to the $35 million received from HCR related to the Royalty Purchase Agreement, net of $1.1 million transaction costs. This was offset by the $10.5 million partial repayment of the MidCap Financial term loan.

On March 30, 2021, we entered into Royalty Purchase Agreement with HCR pursuant to which we sold HCR the right to receive royalty payments made by Pfizer in respect to net sale of RUXIENCE. Under the Royalty Purchase Agreement, we received $35 million at closing and incurred $1.1 million in transaction costs. We are eligible to receive additional payments in aggregate of up to an additional $32.5 million based on achievement of sales milestones in 2021, 2022 and 2023. The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid to us by HCR, we will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter. The Company received the 2021 milestone payments in the collective amount of $10 million in March, 2022 and is eligible to receive additional payments in aggregate of up to $22.5 million based on achievement of sales milestones in 2022 and 2023.

On February ~~2016 as~~28, 2020, Aptevo entered into an LLC Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding limited liability company interests of Aptevo BioTherapeutics LLC, a wholly owned subsidiary of ~~Emergent. To effect the separation, Emergent made a pro rata distribution of Aptevo’s common stock to Emergent’s stockholders on August 1, 2016.~~

Aptevo. In connection with the separation, we received certain assets from Emergent’s biosciences division, including commercial products and development programs, as well as the ADAPTIR platform technology. Certain historical operations that were included by Emergent in its biosciences segment have been reallocated to Emergent’s continuing operations, and as a result the financial statements and discussion and analysis contained herein differ from Emergent’s historically reportable biosciences segment.

Our historical consolidated financial statements for the periods prior to August 1, 2016 have been prepared on a standalone basis and are derived from Emergent’s consolidated financial statements and accounting records. The consolidated financial statements reflect our financial position, results of operations, and cash flows as our business was operated as part of Emergent prioraddition to the ~~separation, in conformity with U.S. Generally Accepted Accounting Principles (GAAP).~~

~~The consolidated financial statements include~~payment received at closing, the ~~allocation~~Company receives deferred payments based on quarterly net sales of ~~certain assets~~IXINITY and liabilities that have historically been held at the Emergent corporate level but which are specifically identifiable or allocable to us. Cash and cash equivalents held by Emergent were not allocated to us unless the cash was held by an entity that was transferred to usmay also earn milestones from Medexus in the ~~distribution. All~~future. Pursuant to our LLC Purchase Agreement, the rate for deferred payments will increase from 2% to 5% of ~~our intracompany transactions and accounts for~~net sales no later than June 30, 2022. For the ~~periods prior~~three months ended March 31, 2022, Aptevo received $0.2 million in deferred payments from Medexus related to ~~August 1, 2016 have been eliminated. Most intercompany transactions between us and Emergent for the periods prior to August 1, 2016 were considered to be effectively settled~~IXINITY sales in the consolidated financial statements at the time the transaction was recorded but for those transition related services. The total net effect of the settlement of these intercompany transactions is reflected in the consolidated statement of cash flows as payment from former parent upon spin-off, net of receivable and net transfer from former parent, prior to spin-off as a financing activity and in the consolidated balance sheet as former parent investment in subsidiary.quarter ended December 31, 2021.

The historical financial statements do not necessarily include all of the expenses that would have been incurred had we been a separate, standalone entity and may not necessarily reflect our results of operations, financial position and cash flows had we been a standalone company during the periods presented. Our consolidated financial statements for the periods prior to August 1, 2016 include an allocation of expenses related to certain Emergent corporate functions, including senior management, legal, human resources, finance, information technology, and quality assurance. These expenses have been allocated to us based on direct usage or benefit where identifiable, with the remainder allocated on a pro rata basis of expenses, headcount, square footage, or other measures. We consider the expense allocation methodology and results to be reasonable for all periods presented. However, the allocations may not be indicative of the actual expense that would have been incurred had we operated as an independent, publicly traded company for the periods presented.Equity Distribution Agreement

On ~~August 31, 2017,~~December 14, 2020, we entered into an ~~LLC purchase agreement~~Equity Distribution Agreement with ~~Saol International Limited (Saol) whereby~~Piper Sandler & Co (Piper Sandler). The Equity Distribution Agreement provides that, upon the terms and subject to the conditions set forth therein, we ~~agreed to~~may issue and sell through Piper Sandler, acting as sales agent, shares of our Hyperimmune Business, which consisted of the following products: WinRho® SDF for autoimmune platelet disorder and hemolytic disease of the newborn; HepaGam B® for the prevention of Hepatitis B following liver transplantation and for treatment following hepatitis B exposure; and VARIZIG® for treatment following exposure to varicella zoster virus for individuals with compromised immune systems.

~~On September 28, 2017, the Company announced that it completed the sale of its Hyperimmune Business to Saol for total consideration~~common stock having an aggregate offering price of up to ~~$74.5~~$50 million. AtWe have no obligation to sell any such shares under the ~~closing~~Equity Distribution Agreement. The sale of the ~~acquisition, Saol paid us an upfront payment totaling $65 million, including $3.25 million which was deposited in an escrow account for the purposes~~shares of ~~satisfying~~our common stock by Piper Sandler, if any, ~~indemnification claims brought by Saol~~will be effected pursuant to a Registration Statement on Form S-3 which we filed on December 14, 2020. We did not issue any shares under the Equity Distribution Agreement in the three months ended March 31, 2022.

The Equity Distribution Agreement will terminate upon the issuance and sale of all shares under the Equity Distribution Agreement or upon the earlier termination thereof at any time by us or Piper Sandler upon notice to the other party.

On December 14, 2020, we filed a Registration Statement on Form S-3 covering the offering, issuance, and sale up to $200 million in common stock, preferred stock, and various series of debt securities and/or warrants to purchase any of such securities, which included the unsold securities from the Prior Registration Statement. On March 29, 2022, we filed an amendment to the prospectus supplement to the Registration Statement on Form S-3 filed on December 14, 2020 pursuant to General Instruction I.B.6 of Form S-3 (General Instruction I.B.6), which updates the amount of shares that we are eligible to sell under the Equity Distribution Agreement. So long as the aggregate market value of our common stock held by non-affiliates is less than $75 million, we will not sell shares under the Equity Distribution Agreement with a value of more than one-third of the aggregate market value of our common stock held by non-affiliates in any 12-month period due to the limitations of General Instruction I.B.6 of Form S-3 and the current public float of our common stock. If our public float increases such that we may sell additional amounts under the Equity Distribution Agreement and the prospectus, we will file another amendment to the prospectus supplement prior to making additional sales. The limitations of General Instruction I.B.6 do not apply to sales of our shares under our Purchase Agreement with Lincoln Park Financial LLC as those sales were committed prior to us being subject to the limitations of General Instruction I.B.6.

On December 20, 2018, we entered into a Purchase Agreement and a Registration Rights Agreement with Lincoln Park Financial LLC (Lincoln Park). Pursuant to the purchase ~~agreement.~~agreement, Lincoln Park has committed to purchase up to $35.0 million worth of our common stock over a 36-month period commencing on February 13, 2019, the date the registration statement covering the resale of the shares was declared effective by the SEC.

Under the Purchase Agreement, on any business day selected by us, we may direct Lincoln Park to purchase shares of our common stock provided that Lincoln Park’s maximum commitment on any single day does not exceed $2.0 million. The purchase price per share will be based off of prevailing market prices of our common stock immediately preceding the time of sale; provided, however, that we cannot direct any such purchase if the prevailing market price is less than $1.00. In addition, we may ~~receive (1) an~~also direct Lincoln Park to purchase other amounts as accelerated purchases or as additional ~~potential milestone payment totaling~~accelerated purchases if the closing sale price of our common stock exceeds certain threshold prices as set forth in the Purchase Agreement.Our 2018 Purchase Agreement and Registration Rights Agreement with Lincoln Park expired in March 2022.

On February 16, 2022, the Company entered into a new Purchase Agreement and a Registration Rights Agreement with Lincoln Park. Under the new Purchase Agreement, Lincoln Park committed to purchase up to ~~$7.5~~$35.0 million ~~related~~worth of our common stock over a 36-month period commencing after the satisfaction of certain conditions, which are within our control, as set forth in the Purchase Agreement. The purchase price per share will be based on prevailing market price; provided, however, that the prevailing market price is not below $1.00. The Company agreed to issue 99,276 shares of our common stock to Lincoln Park for no cash consideration as an initial fee for its commitment to purchase shares of our common stock under the Purchase Agreement. The Company did not issue any shares of common stock for cash consideration to Lincoln Park under the Purchase Agreement in the three months ended March 31, 2022.

Actual sales of shares of our common stock to Lincoln Park under the Purchase Agreement will occur at our discretion from time to time and depend on a variety of factors, including, among others, market conditions, the trading price of our common stock and additional determinations as to the ~~achievement~~appropriate sources of funding for our operations. Lincoln Park has no right to require any sales, but is obligated to make purchases as we direct, in accordance with the Purchase Agreement.

On March 11, 2019, we completed a public offering of common stock and warrants, as follows:

For the three months ended March 31, 2022, the Company did not have any of its warrants exercised. For the three months ended March 31, 2021, certain ~~gross profit milestones~~holders of the Company’s warrants exercised warrants with strike price of $18.20 per share, resulting in the issuance of 27,828 shares of the Company’s common stock and ~~(2) up~~aggregate proceeds to ~~$2.0 million related~~the Company of approximately $0.5 million. As of March 31, 2022 and 2021, there were warrants to ~~collection~~purchase 350,589 and 376,866 shares of ~~certain accounts receivable after~~common stock outstanding, respectively.

We have financed our operations to date primarily through revenue generated from our commercial products, the ~~closing.~~ ~~As a result of~~Royalty Purchase Agreement with HCR, royalty payments from Pfizer, deferred payments from Medexus, the sale of our ~~Hyperimmune Business, we anticipate that~~hyperimmune products business in September 2017, the sale of Aptevo BioTherapeutics on February 28, 2020, public offerings of our ~~future product revenue will decline~~common stock, loan proceeds, milestone payments, research and ~~that we may experience~~development funding from strategic partners, and funds received at the date of our spin-off from Emergent. We had a ~~reduction in expenses~~net loss of $7.7 million and ~~overhead.~~

~~Net income~~$7.3 million for the three months ended ~~September 30, 2017, was $37.9~~March 31, 2022 and 2021, respectively. We had cash and cash equivalents of $35.0 million, restricted cash of $1.3 million and ~~the net loss for~~an accumulated deficit of $221.8 million as of March 31, 2022.

For the three months ended September 30, 2016 was $71.7 million. Net income for the nine months ended September 30, 2017, was $16.7 million and the net loss for the nine months ended September 30, 2016 was $97.5 million. We had an accumulated deficit of $64.0 million as of September 30, 2017. For the nine months ended September 30, 2017,March 31, 2022, net cash ~~provided by~~used in our operating activities was ~~$26.2~~$5.1 million. Although we expect our existing cash and cash equivalents will be sufficient to fund our operations for at least fifteen months from the date of this filing, if we are unable to obtain additional financing when needed, we may have to delay, reduce the scope of, suspend or eliminate one or more of our research and development programs. Following the sale of the Hyperimmune Business, our sole marked product

Our future success is ~~IXINITY~~^®~~, and therefore IXINITY will be our only source of product revenue. As such, our results of operations will be highly~~ dependent on ~~IXINITY sales unless or until~~our ability to develop our product candidates and ultimately upon our ability to attain profitable operations. We anticipate that we ~~develop any of~~will continue to incur significant operating losses for the next several years as we incur expenses to continue to execute on our development strategy to advance our preclinical and clinical stage ~~product candidates.~~assets. We will not generate revenues from our development stage product candidates unless ~~and~~and/or until we or our collaborators successfully complete development and obtain regulatory approval for such product candidates, which we expect will take a number of years and is subject to significant uncertainty. If we obtain regulatory approval for one of our development stage product candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing and distribution, to the extent that such costs are not paid by collaborators. We do not have sufficient cash to complete the clinical development of any of our development stage product candidates and will require additional funding in order to complete the development activities required for regulatory approval of such product candidates.

We have one marketed product, IXINITY coagulation factor IX (recombinant), indicated in adults and children 12 years of age and older with Hemophilia B for control and prevention of bleeding episodes, and management of bleeding during operations.

~~We also have numerous investigational stage product candidates based on our ADAPTIR~~^TM (modular protein technology) platform. The ADAPTIR platform technology can produce monospecific and multispecific immunotherapeutic proteins that specifically bind to one or more targets, for example, bispecific therapeutic molecules, which may have structural and functional

advantages over monoclonal antibodies. The structural differences of ADAPTIR molecules over monoclonal antibodies allow for the development of other ADAPTIR immunotherapeutics that engage immune effector cells and disease targets in a novel manner to produce unique signaling responses and ultimately kill tumors or modulate the immune system to kill tumors. We are skilled at product candidate generation, validation and subsequent preclinical and clinical development using the ADAPTIR platform. We have the ability to progress ADAPTIR molecules from concept to commercialization by way of our protein engineering, preclinical development and process development capabilities, cGMP manufacturing oversight and clinical development capabilities. We also have the ability to launch, market and commercialize these product candidates upon approval.

On July 20, 2017, our wholly owned subsidiary, Aptevo Research and Development LLC, or Aptevo R&D, entered into a collaboration and option agreement with Alligator Bioscience AB, or Alligator, pursuant to which Aptevo R&D and Alligator will collaboratively develop ALG.APV-527, a lead bispecific antibody candidate simultaneously targeting 4-1BB (CD137), a member of the TNFR superfamily of a costimulatory receptor found on activated T cells, and 5T4, a tumor antigen widely overexpressed in a number of different types of cancer. This product candidate is built on our novel ADAPTIR platform, which is designed to expand on the utility and effectiveness of therapeutic antibodies. Under this collaboration agreement, Alligator also granted to Aptevo R&D a time-limited option to enter into a second agreement with Alligator for the joint development of a separate bispecific antibody candidate simultaneously targeting 4-1BB (CD137) and a different tumor antigen.

In accordance with the terms of this Collaboration Agreement, the parties intend to develop the lead bispecific antibody candidate targeting 4-1BB (CD137) through the completion of Phase II clinical trials in accordance with an agreed upon development plan and budget. Subject to certain exceptions for Aptevo R&D’s manufacturing and platform technologies, the parties will jointly own intellectual property generated in the performance of the development activities under the Collaboration Agreement.

Following the completion of the anticipated development activities under the Collaboration Agreement, the parties intend to seek a third-party commercialization partner for this product candidate, or, in certain circumstances, may elect to enter into a second agreement granting rights to either Aptevo R&D or Alligator to allow such partyrequire substantial additional funds to continue ~~the~~our development programs and ~~commercialization of this product. Under the terms of the Collaboration Agreement, the parties intend~~ to share revenue received from a third-party commercialization partner equally, or, if the development costs are not equally shared under the Collaboration Agreement, in proportion to the development costs borne by each party.

The Collaboration Agreement also contains several points in development at which either party may elect to “opt-out” (i.e., terminate without cause) and, following a termination notice period, cease paying development costs for this product candidate, which would be borne fully by the continuing party. Following an opt-out by a party, the continuing party will be granted exclusive rights to continue the development and commercialization of this product candidate, subject to a requirement to pay a percentage of revenue received from any future commercialization partner for this product, or, if the continuing party elects to self-commercialize, tiered royalties on the net sales of this product by the continuing party ranging from the low to mid-single digits, based on the point in development at which the ‘opt-out’ occurs. The parties have also agreed on certain technical criteria or ‘stage gates’ related to the development of this product that, if not met, will cause an automatic termination and wind-down of the Collaboration Agreement and the activities thereunder, provided that the parties do not agree to continue.

~~The Collaboration Agreement contains industry standard termination rights, including for material breach following a specified cure period, and in the case of a party’s insolvency.~~

~~IXINITY~~^® isfulfill our commercial product. It is a coagulation factor IX (recombinant) therapeutic indicated in adults and children 12 years of age and older with hemophilia B for control and prevention of bleeding episodes, and management of bleeding during operations. CMC ICOS Biologics, Inc., or CMC, is the sole manufacturer of bulk drug substance for IXINITY. Patheon UK Limited, acquired by Thermo Fischer Scientific, is currently the sole source fill-finish service manufacturer for IXINITY.

On October 4, 2016, we provided a Notice of Interruption in Manufacturing, or Notice, to the FDA, notifying the FDA of a potential interruption in the supply of IXINITY due to the ongoing manufacturing challenges associated with the manufacturer of the bulk drug substance. On March 15, 2017, we announced the successful manufacture of a new bulk drug substance batch of IXINITY, providing new supply of IXINITY for the commercial market in May 2017.

On June 17, 2017, we entered into a new non-exclusive Amended and Restated Commercial Supply, or Restated Supply Agreement, with CMC for the commercial development and manufacture of IXINITY. Pursuant to the terms of the Restated Supply Agreement, CMC agreed to manufacture IXINITY in the quantity of batches provided to CMC on a twenty-four month rolling forecast. Beginning 2018, the minimum and maximum batches will be four and ten, respectively in a calendar year. Multiple batches ordered in succession with no changeover to another product between batches, or a campaign, shall receive an incremental discounted price.

In accordance with the Restated Supply Agreement, a $7.0 million reserve held by CMC will be will be applied to, at a minimum, the next seven batches manufactured through the end of 2017 as a price concession. As a result, at least the next seven batches will have reduced raw materials or other related CMC costs associated with the inventory. We will also see an impact onour statement of operations due to a lower costs of goods sold associated with this inventory, which will also result in higher gross margins as sales are recognized. Any portion of the $7 million reserve held by CMC that remains unutilized as of December 25, 2017 shall be paid to us in cash on or before December 31, 2017. As of September 30, 2017, $2.6 million has been applied against the reserve and recorded as a reduced cost to inventory. The Restated Supply Agreement has a five-year term renewable with twenty-four months’ prior notice before the expiry of the term for successive two-year terms.

While we do not currently anticipate or foresee a supply shortage or supply interruption occurring, any supply shortage interruption of IXINITY would adversely affect its sales and could adversely affect its market position, commercial viability and the trading price of our common stock.

Except as otherwise stated below, the following discussions of our results of operations reflect the results of our continuing operations, excluding the results related to the Hyperimmune Business. The Hyperimmune Business has been separated from continuing operations and reflected as a discontinued operation. See Note 2 – Sale of Hyperimmune Business, to the accompanying financial statements for additional information.

~~Comparison of the three and nine months ended September 30, 2017 and September 30, 2016~~

We recognized total net income of $37.9 million for the three months ended September 30, 2017 and a net loss of $71.7 million for the three months ended September 30, 2016, and net income of $16.7 million for the nine months ended September 30, 2017 and a net loss of $97.5 million for the nine months ended September 30, 2017. The increase in net income for the three and nine month periods was primarily attributable to the proceeds from the Hyperimmune Business. We recognized net income from continuing operations of $3.0 million for the three months ended September 30, 2017 and a net loss from continuing operations of $73.4 million for the three months ended September 30, 2016. We recognized a net loss from continuing operations of $22.9 million for the nine months ended September 30, 2017 and a net loss from continuing operations of $103.7 million for the nine months ended September 30, 2016. The increase in net income (or decrease in net loss) during the 2017 periods was primarily attributable to an impairment of goodwill and intangible assets charge of $71.0 million during the three and nine months ended September 30, 2016. Our income from discontinued operations for the three months ended September 30, 2017 was $34.9 million, compared to income from discontinued operations for the three months ended September 30, 2016 of $1.7 million. Our income from discontinued operations for the nine months ended September 30, 2017 was $39.6 million, compared to income from discontinued operations for the nine months ended September 30, 2016 of $6.3 million. The increase during the 2017 periods was primarily attributable to the proceeds from the Hyperimmune Business.

Product sales of IXINITY decreased by $0.3 million, to $2.5 million for the three months ended September 30, 2017 from $2.8 million for the three months ended September 30, 2016. This decrease was primarily related to decreased volumes shipped in the third quarter of 2017 as customers increased stock levels with increased orders in the second quarter of 2017 when additional IXINITY product came back to market.

Product sales of IXINITY increased by $1.0 million, to $8.1 million for the nine months ended September 30, 2017 from $7.1 million for the nine months ended September 30, 2016. This increase was primarily related to the expansion of our current Hemophilia B patient base.

In addition to product sales in the third quarter 2017, we recognized $3.7 million of deferred collaboration revenue due to the termination of our collaboration agreement with MorphoSys. Previously we recognized this revenue as services that were performed. As a result of the termination of the collaboration agreement with MorphoSys, we will not recognize any additional revenue under such agreement in any future periods.

The primary expense we incur to deliver IXINITY, our sole marketed products to our customers is manufacturing costs consisting of fixed and variable costs. Variable product costs consist primarily of costs for materials and personnel-related expenses for direct and indirect manufacturing support staff, contract manufacturing and filling operations. Fixed product costs include facilities, utilities and amortization of intangible assets. We determine the cost of product sales for products sold during a reporting period based on the average cost per unit.

Cost of product sales decreased by $2.2 million, or 54%, to $1.9 million for the three months ended September 30, 2017 from $4.1 million for the three months ended September 30, 2016 and decreased by $4.3 million, or 58%, to $3.1 million for the nine months ended September 30, 2017 from $7.4 million for the nine months ended September 30, 2016. The decrease the three-month period was due to a $2.9 million third quarter 2016 write-off of unsaleable IXINITY product. The year-to-date decrease is due to a one-time $3.0 million settlement in the first six months of 2017 related to a dispute between Aptevo and CMC in regards to certain IXINITY batches from 2015 that did not meet manufacturing specifications. Under the terms of the settlement agreement, Aptevo will not pay any additional amounts to CMC for the batches in question, as this was settled for non-cash consideration. This settlement satisfies the monies owed by Aptevo under a 2015 invoice and resolves any claims.planned operating goals.

Due to the ongoing ~~challenges~~COVID-19 pandemic, we may experience delays in opportunities to partner our product candidates, due to financial and other impacts on potential partners. Additionally, we may experience potential impacts on our future deferred payments and milestones from Medexus due to effects of the ongoing COVID-19 pandemic, which may impact Medexus’ ability to continue to successfully commercialize the IXINITY businesses. Additionally, we may experience potential impacts on our future milestones, which are based on global net sales of RUXIENCE, from HCR due to the effects of the ongoing COVID-19 pandemic, which may impact Pfizer’s ability to continue to successfully commercialize the RUXIENCE business. We believe that our existing cash resources, the Investment Amount received pursuant to the Royalty Purchase Agreement with HCR, the ~~manufacture~~cash to be generated from future IXINITY deferred payments, release of restricted cash securing letters of credit, and funds available to us from the remaining principal balance of the Credit Agreement with MidCap Financial, will be sufficient to meet our projected operating requirements and debt service for at least twelve months from the date of filing this Quarterly Report on Form 10-Q.

There are numerous risks and uncertainties associated with research, development, and commercialization of pharmaceutical products. Accordingly, our future funding requirements may vary from our current expectations and will depend on many factors, including, but not limited to:

If we are unable to raise substantial additional capital in the next year, whether on terms that are acceptable to us or at all, then we may be required to:

The sale of additional equity or convertible debt securities may result in additional dilution to our stockholders. If we raise additional funds through the issuance of debt securities or preferred stock or through credit facilities, these securities and/or the loans under credit facilities could provide for rights senior to those of our ~~IXINITY product~~common stock and could contain covenants that ~~meets release specifications for the final drug product, in the third quarter of 2016,~~would restrict our operations.

We have an operating lease related to our office and laboratory space in Seattle, Washington. This lease was amended and extended in March 2019. The term of the amended lease is through April 2030 and we have two options to extend the lease term, each by five years, as well as costs of contract manufacturing services for clinical trial material, and costs of materials used in clinical trials and research and development. Our research and development expenses primarily consist of:

Research and development expenses did not change meaningfully between the three months ended September 30, 2016 and 2017 and decreased by $2.9 million, or 13%, to $19.8 million for the nine months ended September 30, 2017 from $22.8 million for the nine months ended September 30, 2016. This decrease was primarily comprised of:

Selling, general and administrative expenses consist primarily of personnel-related costs and professional fees in support of our executive, sales and marketing, business development, finance, accounting, information technology, legal and human resource functions. Other costs include facility costs not otherwise included in cost of product sales or research and development expenses.

For the three months ended September 30, 2017 selling, general and administrative expenses decreased by $3.6 million, or 33%, to $7.5 million for 2017 from $11.1 million for 2016. This decrease was primarily due to decreased personnel costs in the period.

For the nine months ended September 30, 2017 selling, general and administrative expenses decreased by $1.9 million, or 7%, to $26.0 million for 2017 from $27.9 million for 2016. This decrease was primarily due to lower marketing costs for IXINITY and reduced personnel costs.

Other income (expense), net, consists primarily of interest on debt financing. For the three months ended September 30, 2017, other income (expense) remained flat at an expense of $0.4 million, and for the nine months ended September 30, 2017, increased by $0.9 million, both due to the interest on the loan entered into with Midcap Financial Trust in the last half of 2016.

Benefit from income taxes decreased for the three months ended September 30, 2017 to $13.8 million from $17.6 million for the three months ended September 30, 2016, and decreased to $15.6 million in the nine months ended September 30, 2017 from $18.6 million in the nine months ended September 30, 2016. This tax impact is due to the restatement of our tax liability (see Note 10 – Restatement), as well as the exception to the Intraperiod Tax Allocation rules in accordance with ASC 740-20-45-7. The exception requires that all items (including discontinued operations) be considered in determining the amount of the tax benefit that results for the loss in continuing operations. This deferred tax liability was released to benefit from income taxes upon the impairment of the related IPR& D.

Income tax expense increased to $21.3 million for the three months ended September 30, 2017, from $2.3 million for the three months ended September 30, 2016, and increased to $23.1 million in the nine months ended September 30, 2017 from $3.3 million in the nine months ended September 30, 2016. This income tax expense is due to the impact of the sale of our Hyperimmune Business (see Note 2 – Sale of Hyperimmune Business) and is expected to be reversed in the fourth quarter of 2017.

The preparation of our condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances; however, actual results could differ from those estimates. An accounting policy is considered critical if it is important to a company’s financial condition and results of operations and if it requires the exercise of significant judgment and the use of estimates on the part of management in its application. Although we believe that our judgments and estimates are appropriate, actual results may differ materially from our estimates.

~~We believe the judgments, estimates and assumptions associated with the following critical accounting policies have the greatest potential impact on our consolidated financial statements:~~

For a detailed discussion of these critical accounting policies and significant judgments and estimates, refer to “Critical Accounting Policies and Significant Judgments and Estimates” within “Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2016 that was filed with the SEC on March 31, 2017. There have not been any material changes in our critical accounting policies and significant judgments and estimates as disclosed in our Annual Report Form 10-K for the year ended December 31, 2016.

~~We did not have any off-balance sheet arrangements as of September 30, 2017.~~

~~As of September 30, 2017, we had cash, cash equivalents and investments in the amount of $96.8 million.~~

On August 1, 2016, in connection with the spin-off of the Company from Emergent, we issued 20.2 million shares of our common stock to Emergent stockholders and recorded a contribution from Emergent of $71.2 million. The transactions recorded in 2016 included a one-time payment of $45.0 million, and a working capital reimbursement for outstanding payments of $1.4 million, a noncash transfer of an intangible asset of $0.7 million, and a net transfer of cash from Emergent of $24.2 million. option to terminate the lease in April 2023.

In ~~addition, in the first quarter of 2017 we received $20.0 million as payment for a promissory note issued at the time of the spin-off.~~

~~In addition, on August 4, 2016,~~January 2020, we entered into a ~~$35.0~~contract with The Leukemia & Lymphoma Society (LLS) to be part of an ongoing national AML master clinical trial called the ‘Beat AML Master Clinical Trial.’ The Beat AML Master Clinical Trial provides access to leading academic cancer centers and allows us to study APVO436 in a front-line AML setting. Once we begin participation in the Beat AML Master Clinical Trial, our purchase obligation for the Beat AML Master Clinical Trial may total up to $8.1 million over four years. As of March 31, 2022, we have not begun participation in the Beat AML Master Clinical Trial and we do not currently intend to participate under the current trial design. The Clinical Trial Participation Agreement contains a termination for convenience clause where we may terminate the agreement with 180 days prior written notice. We may re-assess our participation in the master clinical trial as Part 2 (expansion phase) of our Phase 1b APVO436 clinical trial progresses.

On August 5, 2020, we entered into a new Credit and Security Agreement (Credit Agreement), with MidCap ~~Financial Trust.~~Financial. The ~~original~~ Credit Agreement provided us with up to ~~$35.0~~$25 million of available borrowing ~~capacity composed of two tranches of $20.0 million and $15.0 million.~~capacity. The ~~first tranche of $20.0 million was made available to us, and drawn,~~

Emergent’s promise to pay such $20.0 million in cash was evidenced by a non-negotiable, unsecured promissory note issued to us and was paid in48 month term, is interest-only for the first quarter of 2017. Once drawn, interest would be paid monthly while principal would have been paid on a monthly basis commencing in August 2018. The credit agreement will mature on February 1, 2021.

~~The~~annum, subject to a 1.50% LIBOR floor and a 2.50% LIBOR cap. On March 30, 2021, we amended our Credit Agreement ~~covenants require us~~with MidCap Financial and our subsidiaries to maintain increasing minimum net commercial product revenue for each twelve-month period ending on the last day of each calendar quarter. An event of default could result in the accelerationused $10 million of the ~~amounts owed~~proceeds received from the Royalty Purchase Agreement with HCR to pay down the outstanding principal under this agreement from $25 million to $15 million. Additionally, the Company used the $10 million milestone payment received on March 8, 2022, pursuant to our Royalty Purchase Agreement with HCR to further pay down the outstanding principal down to $5 million. The Company’s Credit Agreement currently references LIBOR. The United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, phased out one-week and two-month US Dollar LIBOR settings on December 31, 2021. All other US Dollar LIBOR settings, including the overnight, one-month, three-month, six-month and twelve-month, will be phased out on June 30, 2023. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating LIBOR will be established such that it continues to exist after 2023. Our Credit Agreement with MidCap Financial currently references one-month LIBOR and also provides that we may not have sufficient funds or be able to obtain additional financing to make any accelerated payments. Under these circumstances, our lenders could seek to enforce security interests in our assets securing our indebtedness.

~~On May 11, 2017, we and MidCap Financial Trust entered into an amendment to~~amend the Credit Agreement to ~~among other things, waive the existing event~~reflect an alternative rate of default and revise the financial covenants pertaining to the minimum required commercial product revenue. The amendment revises the following covenants of the Credit Agreement to: (1) extend the time period through which we can draw the second tranche from August 2017 to March 2018, (2) increase the exit fee of 5.75% of the aggregate principal amount under the Credit Agreement for repayment or prepayment other than scheduled amortization payments and the final payment of principal to 6.75% and (3) permit MidCap Financial Trust to obtain an affirmative lien on our intellectual property,interest upon the ~~earlier~~phase out of ~~(i) our draw down of the second tranche or (ii) our cash balance descending below a minimum cash threshold of $25 million.~~LIBOR.

Our principal commitments include obligations under vendor contracts to purchase research services and other purchase commitments with our vendors. In the normal course of business, we enter into services agreements with contract research organizations, contract manufacturing organizations and other third parties. Generally, these agreements provide for termination upon notice, with specified amounts due upon termination based on the timing of termination and the terms of the ~~second amendment,~~agreement. The actual amounts and timing of payments under these agreements are uncertain and contingent upon the ~~agent~~initiation and ~~the lenders agreed that: (i) the commitments~~completion of the ~~lenders~~services to make the remaining $15.0 million tranche of loans under the credit agreement were terminated, (ii) the covenant levels set forth in the minimum net commercial product revenue covenant were revised, (iii) a new covenant requiring us to maintain a minimum $10.0 million unrestricted cash balance, and (iv) the date on which the term loans begin to amortize will be extended to February 1, 2019 if we achieve net commercial product revenues of $16.0 million for the twelve month period ending June 30, 2018 and maintains such level of net commercial product revenues for each quarter prior to February 1, 2019 thereafter.provided.

On September 28, 2017, Saol paid us an upfront payment totaling $65.0 million, including $3.3 million which was deposited in an escrow account for the purposes of satisfying any indemnification claims brought by Saol pursuant to the LLC purchase agreement.

We expect to incur losses from operations for the foreseeable future primarily due to research and development expenses, including expenses related to conducting clinical trials. The Company’s future capital requirements will depend on a number of factors, including:

~~We expect our cash, cash equivalents and investments will support our operations for the next twelve months, at least, based on current operating plans and financial forecasts.~~

~~The following table provides information regarding our cash flows for the nine months ended September 30,~~ ~~2017 and 2016:~~

Net cash used in operating activities of $26.2 million for the nine months ended September 30, 2017 was primarily due to the gain on sale of the Hyperimmune Business. Net cash used in operating activities of $30.2 million for the nine months ended September 30, 2016 was primarily due to our net loss of $97.5 million, which included a one-time impairment of goodwill and intangible assets of $71.0 million.

Net cash provided by investing activities was primarily due to the cash proceeds from the sale of the Company’s Hyperimmune Business and the maturity and redemption of investments of $53.2 million, offset by investment purchases of $29.3 million in the nine months ended September 30, 2017. For the nine months ended September 30, 2016, the largest component of the cash used in investing was $49.8 million in purchases of corporate bonds and US government and agency debt securities.

Net cash provided by financing activities for the nine months ended September 30, 2017 includes the net proceeds received from Emergent at the time of the spin-off in support of a promissory note to support the operations of the Company, offset by $10.0 million in restricted cash in accordance with loan agreement. The net cash provided by financing activities for the nine months ended September 30, 2016 includes $18.0 million in proceeds from long-term debt, as well as $70.5 million for two contributions from Emergent.

Our future minimum contractual commitments and obligations were reported in our Annual Report on Form 10-K for the year ended December 31, 2016 that was filed with the SEC on March 14, 2017. Our future minimum contractual obligations and commitments have not changed materially from the amounts previously reported.

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended ~~September 30, 2017,~~March 31, 2022, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We may from time to time be named as a party to legal claims, actions and complaints, including matters involving employment claims, our intellectual property or other third-party claims. Our management believes that there are currently no claims or actions pending against us, the ultimate disposition of which could have a material adverse effect on our results of operations, financial condition or cash flows.

We are subject to significant risks and uncertainties that could impact the Company’s businesses, results of operations and financial condition, including by causing our actual results to differ materially from those projected in any forward-looking statements. Additional risks and uncertainties that are not currently known to the Company or management or that are not currently believed by the Company or management to be material may also harm the Company’s business, financial condition and results of operation. You should carefully consider the following risks and other information in this ~~quarterly report~~Quarterly Report on Form 10-Q in evaluating us and our common stock. ~~Any~~

The following is a summary of the ~~following~~material risks ~~could materially~~to our business, operations, and ~~adversely affect Aptevo’s results~~ownership of ~~operations, financial condition or financial prospects.~~our common stock:

Our historical consolidated financial data prior to August 1, 2016 was prepared on a “carve-out” basis from the financial information of Emergent and shows that had we been a standalone company, we wouldWe have ~~had a history of~~experienced significant operating losses and we may ~~be unable to~~not achieve profitability ~~going forward.~~

~~Although for~~in the future.

We will require additional capital and may be unable to raise capital when needed or on acceptable terms.

As of ~~September 30, 2017,~~March 31, 2023, we had cash, cash equivalents, and ~~investments~~restricted cash in the amount of ~~$96.8~~$36.3 million. We will require additional funding to grow our business including to support the ongoing clinical development of APVO436, develop additional products, support commercial marketing activities or otherwise provide additional financial flexibility. If we are not able to secure adequate additional funding, we may need to make reductions in spending. This may include extending payment terms with suppliers, liquidating assets, and suspending or curtailing planned programs. We may also have to delay, reduce the scope of, suspend or eliminate one or more research and development programs. A failure to raise the additional funding or to effectively implement cost reductions could harm our business, results of operations and future prospects. Our future capital requirements will depend on many factors, including:

If our capital resources are insufficient to meet our future capital requirements, we will need to finance our cash needs through bank loans, public or private equity or debt offerings, ~~a sale of commercial assets,~~ collaboration and licensing arrangements, or other strategic transactions. Future issuances of common stock may include (i) any sale of up to the remaining $50.0 million worth of shares of our common stock pursuant to our Equity Distribution Agreement with Piper Sandler & Co entered into in December 2020, (ii) any sale of up to $35 million worth of shares of our common stock to issue from our Purchase Agreement withLincoln Park Capital Fund, LLC, or Lincoln Park, entered

into in February 2022, and (iii) the issuance of up to 350,589 remaining outstanding shares of common stock upon the exercise of warrants issued in connection with our March 2019 public offering of common stock and warrants. Public or bank debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, pursuing acquisition opportunities, or declaring dividends. If we raise funds by issuing equity securities, our stockholders will experience dilution. If we raise funds through collaboration and licensing arrangements with third parties or enter into other strategic transactions, it may be necessary to relinquish valuable rights to our technologies or product candidates or grant licenses on terms that may not be favorable to us.

Further, SEC regulations limit the amount of funds we can raise during any 12-month period pursuant to our shelf registration statement on Form S-3. On March 29, 2022, we filed an amendment to the prospectus related to the Registration Statement on Form S-3 filed on December 14, 2020 pursuant to General Instruction I.B.6 of Form S-3 (General Instruction I.B.6), which updates the amount of shares that we are eligible to sell under the Equity Distribution Agreement. So long as the aggregate market value of our common stock held by non-affiliates is less than $75 million, we will not sell shares under the Equity Distribution Agreement with a value of more than one-third of the aggregate market value of our common stock held by non-affiliates in any 12-month period due to the limitations of General Instruction I.B.6 of Form S-3 and the current public float of our common stock. The limitations of General Instruction I.B.6 do not apply to sales of our shares under our Purchase Agreement with Lincoln Park Financial LLC as those sales were committed prior to us being subject to the limitations of General Instruction I.B.6. If we are required to file a new registration statement on another form, we may incur additional costs and be subject to delays in raising capital due to review by SEC staff.

Current economic conditions, including the impact of the ongoing COVID-19 pandemic on our operations or on the global economy and capital markets, may make it difficult to obtain additional financing on attractive terms, or at all. If financing is unavailable or lost, our business, results of operations, financial condition and financial prospects would be adversely affected and we could be forced to delay, reduce the scope of or eliminate many of our planned activities.

Our business ~~depends~~is affected by macroeconomic conditions, including rising inflation, interest rates and supply chain constraints.

Various macroeconomic factors could adversely affect our business and the results of our operations and financial condition, including changes in inflation, interest rates and overall economic conditions and uncertainties such as those resulting from the current and future conditions in the global financial markets. For instance, inflation could negatively impact the Company by increasing our labor costs, through higher wages and higher interest rates. Recent supply chain constraints have led to higher inflation, which if sustained could have a negative impact on the ~~continued success~~Company's product development and operations. If inflation or other factors were to significantly increase our business costs, our ability to develop our current pipeline and new therapeutic products may be negatively affected. Interest rates, the liquidity of ~~IXINITY.~~

~~We currently have only one revenue-generating product, IXINITY, following~~ the ~~sale~~credit markets and the volatility of the capital markets could also affect the operation of our ~~three hyperimmune products, WinRho SDF, HepaGam B~~business and ~~VARIZIG. We expect revenues from~~our ability to raise capital in order to fund our operations. Similarly, these macroeconomic factors could affect the ability of our third-party suppliers and manufacturers to manufacture all clinical trial materials for our product candidates.

Actions of activist stockholders against us have been and could be disruptive and costly and may cause uncertainty about the strategic direction of our business.

Stockholders have in the past and may, from time to time, engage in proxy solicitations or advance stockholder proposals, or otherwise attempt to effect changes and assert influence on our board of directors and management. For example, on February 9, 2021, Tang Capital Partners LP, Tang Capital Management, LLC and Kevin Tang (collectively, “Tang”) submitted an advisory stockholder proposal for consideration at our 2021 annual meeting of stockholders to commence a process to sell Aptevo to the highest bidder. Activist campaigns that contest or conflict with our strategic direction or seek changes in the composition of our board of directors or management could have an adverse effect on our operating results and financial condition. A proxy contest would require us to incur significant legal and advisory fees, proxy solicitation expenses and administrative and associated costs and require significant time and attention by our board of directors and management, diverting their attention from the pursuit of our business strategy. Any perceived uncertainties as to our future direction and control, our ability to execute on our strategy, or changes to the composition of our board of directors or senior management team arising from a proxy contest could lead to the perception of a change in the direction of our business or instability which may result in the loss of potential business opportunities, make it more difficult to pursue our strategic initiatives, or limit our ability to attract and retain qualified personnel and business partners, any of which could adversely affect our business and operating results. If individuals are ultimately elected to our board of directors with a specific agenda, it may adversely affect our ability to effectively implement our business strategy and create additional value for our stockholders. We may choose to initiate, or may become subject to, litigation as a result of a proxy contest or matters arising from the proxy contest, which would serve as a further distraction to our board of directors and management and would require us to incur significant additional costs. In addition, actions such as those described above could cause significant fluctuations in our stock price based upon temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Our future income will depend, in part, on the ability of Medexus to successfully further develop, market and commercialize IXINITY, resulting in milestone payments and deferred payments to the Company by Medexus.

On February 28, 2020, we entered into a Purchase Agreement with Medexus, pursuant to which we sold all of the issued and outstanding limited liability company interests of Aptevo BioTherapeutics, a subsidiary of Aptevo that wholly owns the IXINITY and related Hemophilia B business. We are entitled to receive future potential payments to the extent of the achievement of certain regulatory and commercial milestones and through deferred payments based on net sales of IXINITY. Royalties are earned at the rate of 2% of net revenue through the earlier of June 2022 or completion of the IXINITY pediatric trial being run by Medexus. After that, the royalty rate will increase to 5%. We no longer control the development, marketing, and commercialization of IXINITY and are dependent on Medexus to successfully do so. Although Medexus has agreed to use commercially reasonable efforts to commercialize IXINITY in the ordinary course of business in good faith, Medexus may not commit adequate resources to the further development, marketing, and commercialization of IXINITY, may experience financial difficulties, may face competition, or may prioritize other products or initiatives. Due to the effect of the ongoing COVID-19 pandemic on the current and future environment for clinical development and regulatory approval, Medexus’ ability to continue to ~~account for~~successfully commercialize the IXINITY business may be affected, and we may experience potential impacts on our future deferred payments from Medexus. The failure of Medexus to successfully market and commercialize IXINITY, including because of factors outside of Medexus’ control, could result in lower than expected milestone or deferred payments to us and negatively impact our future financial and operating results.

Our operating results are difficult to predict and will likely fluctuate from quarter to quarter and year to year, as a ~~portion~~result of a variety of factors, including:

Due to the ongoing COVID-19 pandemic, we may experience delays in opportunities to partner our product candidates, due to financial and other impacts on potential partners. Additionally, we may experience potential impacts on our future milestone or deferred payments from Medexus, which may impact Medexus’ ability to continue to successfully commercialize the IXINITY businesses. In 2022, we continue to see an impact of the spread of the COVID-19 virus and its variants on our business as some of our ~~revenue. The commercial success of IXINTY depends upon:~~

~~The failure to maximize the financial contribution of IXINITY could~~ have a material adverse effect on our business, ~~financial condition,~~ results of operations and growth prospects. We may choose to increase the price of IXINITY, and these price adjustments may negatively affect our sales volumes. In addition, our product sales may fluctuate significantly from quarter to quarter, dependingfinancial condition.

Our future cash flow will depend, in part, on the ~~number~~ability of ~~patients receiving treatment, the availability~~Pfizer to successfully sell RUXIENCE and our receipt of ~~supply~~milestone and royalty payments from HCR in connection therewith. If Pfizer is unable, or does not devote sufficient resources, to ~~meet the demand for IXINITY, the dosing requirements of treated patients and other factors. If~~maintain or continue increasing sales of ~~IXINTY were to decline, we could be required to make an allowance for excess~~RUXIENCE, or ~~obsolete inventory, increase our provision for product returns, or we could incur other costs related to operating our business, each of which could negatively impact~~if HCR does not comply with the Royalty Purchase Agreement, our results of operations ~~and our financial condition. We are constantly evaluating commercial and strategic transactions to generate revenue~~will be adversely affected.

On June 25, 2020, we announced that ~~include any current collaborations and collaborations or a sale of assets in the future.~~

~~To preserve the tax-free treatment of the distribution~~we will receive royalty payments from Pfizer related to the separation, together with certain related transactions, we are restricted under the tax matters agreement that we entered into with Emergent, from taking any action that prevents such transactions from being tax-free for U.S. federal income tax purposes. In particular, for a period of two years following the separation, we are restricted from taking certain actions (including restrictions on share issuances, business combinations, sales of ~~assets, amendments to organizational documents~~a rituximab biosimilar product, RUXIENCE (Rituximab-pvvr), which was approved by the U.S. Food and similar transactions) that could cause the distribution, together with certain related transactions, to fail to qualify as a tax-free transaction for U.S. federal income tax purposes. These restrictions may limit our ability to pursue certain strategic transactions or engageDrug Administration in ~~other transactions that might increase the value of our business, including use of our common stock to make acquisitions~~July 2019 and equity capital market transactions. In addition, under the tax matters agreement, we are required to indemnify Emergent against any tax liabilities and related expenses arising from the failure of the distribution, together with certain related transactions, to be tax-free to the extent such failure is attributable to actions, events or transactions relating to our stock, assets or business, including the acquisition of our stock even if we did not participate in or otherwise facilitate the acquisition.

~~We may not achieve profitability in future periods or on a consistent basis.~~

Although for the three and nine months ended September 30, 2017, we had net income of $37.9 million and $16.7 million, respectively, this net income was the result of our receipt of proceeds from the sale of our three hyperimmune products in September 2017. Our ability to become profitable in future periods will be substantially dependent on our product sales revenues from the sales of IXINITY and revenues from any current collaboration and licensing arrangements and any arrangements entered into in the future. Accordingly, our ability to become profitable may be adversely affected as we progress through various stages of ongoing or planned clinical trials for our product candidates. We may not be able to achieve profitability. We anticipate needing to generate greater revenue in future periods from IXINITY or our product candidates in development. If we are unable to generate greater revenue, we may not achieve profitability in future periods, and may not be able to maintain any profitability we do achieve. If we are unable to generate sufficient revenues, we will not become profitable and may be unable to continue operations without additional funding.

~~The terms of our credit agreement may restrict the operation of our business and limit the cash available for investment in our business operations.~~

~~On August 4, 2016, we entered into a Credit and Security Agreement, or the Credit Agreement,~~launched by and among us and certain our subsidiaries as borrowers, MidCap Financial Trust, as agent, and the lenders from time to time party thereto. The terms of the Credit Agreement, and its subsequent amendments, and borrowings we may make under the Credit Agreement in the future, could have significant adverse consequences for our business, including:

As of March 31, 2017, our net commercial product revenue did not meet the required minimum for the twelve months ended March 31, 2017. As a result, on May 11, 2017, we and MidCap Financial Trust entered into an amendment to the Credit Agreement to, among other things, waive the existing event of default and revise the financial covenants pertaining to the minimum required commercial product revenue. The amendment revises the following covenants of the Credit Agreement to: (1) extend the time period through which we can draw the second tranche from August 2017 to March 2018 (2) increase the exit fee of 5.75% of the aggregate principal amount under the Credit Agreement for repayment or prepayment other than scheduled amortization payments and the final payment of principal to 6.75% and (3) permit MidCap Financial Trust to obtain an affirmative lien on our intellectual property, upon the earlier of (i) our draw down of the second tranche or (ii) our cash balance descending below a minimum cash threshold of $25 million.

On September 28, 2017, we entered into a second amendment of the Credit Agreement (Amendment No. 2) in order to permit the sale of the Hyperimmune Business under the LLC purchase agreement (described in Note 2 - Sale of Hyperimmune Business, in the notes to the financial statements), and to reflect changes in the remaining business as a result of such sale.

Pursuant to the amendment, the agent and the lenders consented to the LLC purchase agreement and the consummation of the sale transaction, released Midcap Financial Trust’s liens on the assets transferred to Venus BioTherapeutics Sub LLC (Venus), one of our subsidiaries, prior to the sale, and agreed that no prepayment of the term loans under the credit agreement would be required as a result the sale.

As part of the amendment, the agent and the lenders agreed that: (i) the commitments of the lenders to make the remaining $15.0 million tranche of loans under the credit agreement were terminated, (ii) the covenant levels set forth in the minimum net commercial product revenue covenant were revised, (iii) a new covenant requiring us to maintain minimum unrestricted cash balances was added to the credit agreement, and (iv) the date on which the term loans begin to amortize will be extended to February 1, 2019 if we achieve commercial product revenues of $16.0 million for the twelve month period ending June 30, 2018 and maintain such level of net commercial product revenues for each quarter prior to February 1, 2019 thereafter.

We may not have sufficient funds or be able to obtain additional financing to pay the amounts due under any future borrowings under the Credit Agreement. In addition, failure to comply with the covenants, including but not limited to the revenue covenants, under the Credit Agreement could result in an event of default. An event of default could result in the acceleration of amounts due under the Credit Agreement, and we may not be able to obtain additional financing to make any accelerated payments. Under these circumstances, our lenders could seek to enforce security interests in our assets securing our indebtedness.

~~Our results of operations and liquidity needs could be materially negatively affected by market fluctuations and economic downturns.~~

~~Our results of operations could be materially negatively affected by general economic conditions, both~~Pfizer in the United States and ~~elsewhere around the world. Continuing concerns over inflation, energy costs, geopolitical issues,~~Japan in early 2020, and the ~~availability~~European Union in the third quarter of 2020. The payments from Pfizer relate to a Collaboration and ~~cost~~License Agreement acquired by us as part of ~~credit~~our spin-off from Emergent in 2016, which applies a fixed royalty rate of 2.5% on global net sales. The agreement was originally executed by Trubion Pharmaceuticals (which was subsequently acquired by Emergent) and Wyeth (a wholly-owned subsidiary of Pfizer). The royalty term runs until the seventh anniversary of the first commercial sale of the biosimilar. Royalty payments to us are due within 60 days after the end of each quarter. Although the agreement was terminated in 2012, the royalty obligation thereunder survived.

On March 30, 2021, we entered into and closed a Royalty Purchase Agreement with HCR (Royalty Purchase Agreement) pursuant to which we sold to HCR the right to receive royalty payments made by Pfizer in respect of net sales of RUXIENCE. Under the terms of the Royalty Purchase Agreement, we received $35 million at closing and we are eligible to receive additional payments in aggregate of up to an additional $32.5 million based on the achievement of sales milestones in 2021, 2022 and 2023. The Royalty Purchase Agreement further provides that, once HCR reaches aggregate royalty payments totaling 190% of the Investment Amount plus the Milestone Amounts to the extent paid to us by HCR, we will be entitled to receive 50% of any additional royalty payments by Pfizer thereafter. The Company received the 2021 milestone payments in the collective amount of $10 million on March 8, 2022. The proceeds from these milestone payments, net of transaction costs, were recorded as an additional liability related to the sale of royalties on the consolidated balance sheet as of March 31, 2022. The Company is eligible to receive additional payments in the aggregate of up to $22.5 million based on achievement of sales milestones in 2022 and 2023.

We have ~~contributed~~no control over the sales of RUXIENCE and are therefore dependent on the efforts and ability of Pfizer to ~~increased volatility~~generate net sales of RUXIENCE sufficient for us to receive Milestone Payments and ~~diminished expectations for~~additional royalty payments under the ~~economy~~Royalty Purchase Agreement. The failure of Pfizer to successfully generate such net sales could negatively impact our future financial and ~~the markets going forward. Domestic~~operating results and international equity markets continue to experience heightened volatility and turmoil. These events and the continuing market upheavals may have an adverse effect on us. In the event of a continuing market downturn, our results of operations could therefore be adversely ~~affected by those factors in many ways, including making it more difficult~~affected. Additionally, even if Pfizer is able to generate net sales of RUXIENCE sufficient for us to ~~raise funds,~~receive such payments, if ~~necessary, and our stock price~~HCR breaches the Royalty Purchase Agreement (for example, by not making required payments when due, or at all), disputes or litigation may ~~further decline.~~

~~The way that we account for our operational and business activities is based on estimates and assumptions that may differ from actual results.~~

The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, our management evaluates its critical estimates and judgments, including, among others: those related to revenue recognition, including product rebates, chargeback and return accruals; inventory; clinical research costs; business combinations; intangible assets and impairment; income taxes; stock-based compensation; and contingent consideration. Those critical estimates and assumptions are based on our historical experience, future projections, our observance of trends in the industry, and various other factors that are believed to be reasonable under the circumstances, and they form the basis for making judgments about the carrying values and fair values of assets and liabilities that may not be readily apparent from other sources. If actual results differ from these estimates as a result of unexpected conditionsarise. Such disputes or ~~events occurring which cause us to have to reassess our assumptions, there~~litigation could be ~~a material adverse impact on~~time-consuming and expensive and could adversely affect our ~~financial results and the performance of our stock.~~business.

We face product liability exposure, which could cause us to incur substantial liabilities and negatively affect our business, financial condition, and results of operations.

The nature of our business exposes us to potential liability inherent in pharmaceutical products, including with respect to the ~~sale of IXINITY, any other product candidates that we successfully develop and the~~ testing of our product candidates in clinical ~~trials.~~trials and any product candidates that we successfully develop. Product liability claims might be made by patients in clinical trials, consumers, health care providers or pharmaceutical companies or others that sell ~~our products.~~any products that we successfully develop. These claims may be made even with respect to those products that are manufactured in licensed and regulated facilities or otherwise ~~possess~~receive regulatory approval for study or commercial ~~sale or study.~~sale. We cannot predict the frequency, outcome or cost to defend any such claims.

If we cannot successfully defend ourselves against future claims that ~~IXINITY or~~ our product candidates caused injuries, we may incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

The amount of insurance that we currently hold may not be adequate to cover all liabilities that may occur. Further product liability insurance may be difficult and expensive to obtain. We may not be able to maintain insurance coverage at a reasonable cost and we may not be able to obtain insurance coverage that will be adequate to satisfy all potential liabilities. Claims or losses in excess of our product liability insurance coverage could have a material adverse effect on our business, financial condition, and results of operations. The cost of defending any ~~products~~product liability litigation or other proceeding, even if resolved in our favor, could be substantial. Uncertainties resulting from the initiation and continuation of ~~products~~product liability litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Product liability claims, regardless of merit or eventual outcome, may absorb significant management time and result in reputational harm, potential loss of revenue from decreased demand for ~~our products and/or~~any product candidates we successfully develop, withdrawal of clinical trial participants and potential termination of clinical trial sites or entire clinical programs, and could cause our stock price to fall.

Product recalls may be issued at our discretion or at the discretion of our suppliers, government agencies and other entities that have regulatory authority for pharmaceutical sales. Any recall of IXINITY could materially adversely affect our business by rendering us unable to sell IXINITY for some time and by adversely affecting our reputation. A recall could also result in product liability claims by individuals and third-party payors. In addition, product liability claims could result in an investigation of the safety or efficacy of IXINITY, our manufacturing processes and facilities, or our marketing programs conducted by the FDA, the European Medicines Agency, or EMA, or the competent authorities of the EU Member States. Such investigations could also potentially lead to a recall of IXINITY or more serious enforcement actions, limitations on the indications for which they may be used, or suspension, variation, or withdrawal of approval. Any such regulatory action by the FDA, the EMA or the competent authorities of the EU Member States could lead to product liability lawsuits as well.

We rely significantly on information technology systems and any failure, inadequacy, interruption or security lapse of that technology, including any cyber security incidents, could harm our ability to operate our business effectively or result in data leakage of proprietary and confidential business and employee information.

Our business is increasingly dependent on critical, complex and interdependent information technology systems, including Internet-based systems, to support business processes as well as internal and external communications. The size and complexity of our computer systems make them potentially vulnerable to interruption, invasion, computer viruses, destruction, malicious intrusion and additional related disruptions, which may result in the impairment of production and key business processes.

In addition, our systems are potentially vulnerable to data security breaches—whether by employee error, malfeasance or other disruption—which may expose sensitive data to unauthorized persons. Such data security breaches could lead to the loss of trade secrets or other intellectual property, or could lead to the public exposure of personal information, including sensitive personal information, of our employees, clinical trial patients, customers and others. A significant business disruption or a breach in security resulting in misappropriation, theft or sabotage with respect to our proprietary and confidential business and employee information could result in financial, legal, business or reputational harm to us, any of which could adversely affect our business, financial condition and operating results.

Our success is dependent on our continued ability to attract, motivate and retain key personnel, and any failure to attract or retain key personnel may negatively affect our business.

Because of the specialized scientific nature of our business, our ability to develop products and to compete with our current and future competitors largely depends upon our ability to attract, retain and motivate highly qualified managerial and key scientific and technical personnel. If we are unable to retain the services of one or more of the principal members of senior management, including our Chief Executive Officer, Marvin L. White, our Chief Financial Officer, Jeffrey G. Lamothe, ~~and~~ our ~~Chief Medical Officer, Scott C. Stromatt,~~General Counsel, SoYoung Kwon, our VP of Finance, Daphne Taylor, or other key employees, our ability to implement our business strategy could be materially harmed. ~~Our industry has experienced a high rate of turnover of management personnel in recent years.~~ We face intense competition for qualified employees from biotechnology and pharmaceutical companies, research organizations and academic institutions. Moreover, we have recently experienced increased levels of attrition. Attracting, retaining or replacing these personnel on acceptable terms may be difficult and time-consuming given the high demand in our industry for similar personnel. We believe part of being able to attract, motivate and retain personnel is our ability to offer a competitive compensation package, including equity incentive awards. If we cannot offer a competitive compensation package or otherwise attract and retain the qualified personnel necessary for the continued development of our business, we may not be able to maintain our operations or grow our business. Due to our equity plan proposal not receiving stockholder approval at the Company’s annual meeting in 2021, we currently do not have sufficient equity available to award 2022 annual grants to employees and may not have sufficient equity to attract and retain qualified personnel assuming such grants are consistent with our historical practices. In addition, we have experienced and may experience an impact on the health of key personnel due to the ongoing COVID-19 pandemic.

The ongoing COVID-19 pandemic, including the continued identification of the new variants of the COVID-19 virus, could adversely impact our business, including our clinical trials.

Since March of 2020, a novel strain of coronavirus, COVID-19, has spread through the world, including the United States. The COVID-19 pandemic has caused severe global economic and societal disruptions and uncertainties, and we have experienced disruptions that have impacted our business and clinical trials, including, limitation of company operations, implementing work from home policies and office closures; delays or difficulties in receiving deliveries of critical experimental materials; delays or difficulties in enrolling patients in our clinical trials; delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff; diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; interruption of key clinical trial activities, such as patient enrollment and clinical trial site monitoring; and, limitations in employee resources that would otherwise be focused on our business, including the conduct of our research and development activities and process development activities, due to the illness of employees or their families, or the preference of employees to avoid contact with large groups of people.

We may continue to experience disruptions in the future, or additional disruptions that could severely impact our business, such as delays or difficulties to the financing environment and raising capital due to economic uncertainty; delays in opportunities to partner our product candidates, due to financial and other impacts on potential partners; diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials; potential impacts on our future deferred payments and milestones from Medexus due to the environment which may impact Medexus’ ability to continue to successfully commercialize the IXINITY business or Pfizer to successfully commercialize RUXIENCE; and negative impacts on suppliers and licensees. The global spread of COVID-19 continues to rapidly evolve, including through the identification of the new variants of the virus. The ongoing COVID-19 pandemic may also result in the need to suspend enrollment into studies, patient withdrawals, postponement of preclinical studies, study modification, suspension, or termination, the introduction of remote study procedures and modified informed consent procedures, study site changes, direct delivery of investigational products to patient homes requiring state licensing, study deviations or noncompliance, and changes or delays in site monitoring. The foregoing may require that we consult with relevant review and ethics committees and the FDA or comparable foreign regulatory authorities. The foregoing may also impact the integrity of our study data. The pandemic could further impact our ability to interact with the FDA or other regulatory authorities, and may result in delays in the conduct of inspections or review of pending submissions.

The ongoing COVID-19 pandemic may further impact our suppliers and manufacturers. If any of our suppliers or manufacturers are adversely impacted by the COVID-19 pandemic or the restrictions resulting from the pandemic, if they cannot obtain the necessary supplies, or if such third parties need to prioritize other products or customers over us, including under the Defense Production Act, we may experience delays or disruptions in our supply chain, which could have a material and adverse impact on our business and development plans. Third party manufacturers may also need to implement measures and changes, or deviate from typical requirements, because of the COVID-19 pandemic that may otherwise adversely impact our supply chains or the quality of the resulting products or supplies. Depending on the change, we may need to obtain FDA pre-approval or otherwise provide FDA with a notification of the change.

The ongoing COVID-19 pandemic may result in changes in laws, policies, and regulations. By example, due to the potential impact of the COVID-19 pandemic on clinical trials, drug development, and manufacturing, FDA issued guidance several times concerning how sponsors and investigators may address these challenges. FDA’s guidance is continually evolving. By further example, in March 2020, the U.S. Congress passed the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, which includes various provisions regarding FDA drug shortage reporting requirements, as well as provisions regarding supply chain security, such as risk management plan requirements, and the promotion of supply chain redundancy and domestic manufacturing. This and any future changes in law may require that we change our internal processes and procedures to ensure continued compliance.

The extent to which the ongoing COVID-19 pandemic may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions, the effectiveness of actions taken in the United States and other countries to contain and treat the disease, including the effectiveness of vaccination programs, and whether businesses and the economy in general will continue to reopen and stay open.

The terms of our credit agreement may restrict the operation of our business and limit the cash available for investment in our business operations.

In August 2020, we entered into a Credit and Security Agreement (the Credit Agreement), by and among us and certain of our subsidiaries as borrowers, MidCap Financial, as agent, and the lenders from time to time party thereto. The terms of the Credit Agreement and borrowings we may make under the Credit Agreement in the future, could have significant adverse consequences for our business, including:

We may not have sufficient funds or be able to obtain additional financing to pay the amounts due under the Credit Agreement. In addition, failure to comply with the covenants under the Credit Agreement, including those outside of our control, could result in an event of default. An event of default could result in the acceleration of amounts due under the Credit Agreement, and we may not be able to obtain additional financing to make any accelerated payments. Under these circumstances, our lenders could seek to enforce security interests in our assets securing our indebtedness, including our intellectual property.

We completed a Section 382 study and have concluded that we experienced an “ownership change” as defined in Section 382 of the U.S. Internal Revenue Code of 1986, as amended (the Code), and thus the tax benefits of our pre-“ownership change” net operating loss carryforwards and certain other tax attributes will be subject to an annual limitation under Sections 382 and 383 of the Code.

In general, a corporation undergoes an “ownership change” under Section 382 of the Code if, among other things, the stockholders who own, directly or indirectly, 5% or more of the corporation’s stock (by value), or are otherwise treated as “5% stockholders” under Section 382 of the Code and the Treasury regulations promulgated thereunder, increase their aggregate percentage ownership (by value) of the corporation’s stock by more than 50 percentage points over the lowest percentage of stock owned by the 5% stockholders at any time during the applicable testing period, which is generally the rolling three-year period preceding the date of the potential ownership change testing event. Such potential ownership change testing events include changes involving a stockholder becoming a 5% stockholder or arising from a new issuance of capital stock or share repurchases by the corporation, subject to certain exceptions.

In the event of an “ownership change,” Sections 382 and 383 of the Code impose an annual limitation on the amount of taxable income a corporation may offset with pre-change net operating loss carryforwards and certain other tax attributes. The annual limitation is generally equal to the value of the outstanding stock of the corporation immediately before the ownership change (excluding certain capital contributions), multiplied by the long-term tax-exempt rate as published by the IRS for the month in which the ownership change occurs (the long-term tax-exempt rate for November 2020 is 0.89%). Any unused annual limitation may generally be carried over to subsequent years until the pre-ownership change net operating loss carryforwards and certain other tax attributes expire or are fully utilized by the corporation. Similar provisions of state tax law may also apply to limit the use of state net operating loss carryforwards and certain other tax attributes.

Additionally, Section 382 of the Code includes special rules that apply to a corporation with a significant amount of net unrealized built-in gains or net unrealized built-in losses in its assets immediately prior to ownership change under Section 382 of the Code. In general, certain built-in gains recognized during the five-year period beginning on the date of the ownership change increases the corporation’s annual limitation under Sections 382 and 383 of the Code in the taxable year that such built-in gains are recognized or deemed recognized (but only up to the amount of the net unrealized built-in gain), while certain built-in losses recognized during such five-year period are subject to ~~periodic litigation,~~the annual limitation under Section 382 of the Code (but only up to the amount of the net unrealized built-in loss).

As of December 31, 2021, we had approximately $159.6 million and $70.3 million of federal and state net operating loss carryforwards, respectively, available to reduce future taxable income that will begin to expire in 2037 for federal income tax purposes. These net operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Federal net operating loss carryforwards incurred in 2018 and in future years may be carried forward indefinitely, but the usage of such federal net operating loss carryforwards is limited. We completed an IRC Section 382 study on our federal tax attributes in connection to ownership change in 2020 and determined that the annual utilization of federal net operating loss and certain other tax attribute carryforwards is limited. It is not expected that the annual limitations will result in the expiration of tax attribute carryforwards prior to utilization assuming sufficient income.

We cannot predict or control the occurrence or timing of another ownership change under Section 382 of the Code in the future. In addition, it is possible that any offering of securities by us could result in an ownership change. If another ownership change were to occur, future limitations could apply to our net operating losses and certain other tax attributes, which could result in ~~losses~~a material amount of our net operating loss carryforwards and certain other tax attributes becoming unavailable to offset future income tax liabilities.

The realization of all or ~~unexpected expenditure~~a portion of ~~time~~our deferred income tax assets (including net operating loss carryforwards) is dependent upon the generation of future income during the statutory carryforward periods. Our inability to utilize our limited pre-ownership change net

operating loss carryforwards and ~~resources.~~certain other tax attributes, or the occurrence of a future ownership change and resulting additional limitations to these tax attributes, could have a material adverse effect on our financial condition, results of operations and cash flows.

~~From~~Our investments are subject to market and credit risks that could diminish their value and these risks could be greater during periods of extreme volatility or disruption in the financial and credit markets, which could adversely impact our business, financial condition, results of operations, liquidity and cash flows.

Our investments are subject to risks of credit defaults and changes in market values. Periods of macroeconomic weakness or recession, heightened volatility or disruption in the financial and credit markets could increase these risks, potentially resulting in other-than-temporary impairment of assets in our investment portfolio. The impact of geopolitical tension, such as a deterioration in the bilateral relationship between the US and China or increasing escalation of conflict between Russia and Ukraine, including any additional sanctions, export controls or other restrictive actions that may be imposed by the US and/or other countries against governmental or other entities in, for example, Russia, also could lead to disruption, instability and volatility in the global markets, which may have an impact on our investments across negatively impacted sectors or geographies.

The results of our current and planned preclinical studies and clinical trials may not satisfy the requirements of the FDA or non-U.S. regulatory authorities. Results from early-preclinical studies and clinical trials may not be predictive of results from later-stage or other trials and interim or top line data may be subject to change or qualification based on the complete analysis of data.

We are very early in our Phase 1b clinical trial with APVO436 and none of our other product candidates have entered clinical development. Clinical failure can occur at any stage of preclinical or clinical development. Preclinical studies and clinical trials may produce negative or inconclusive results. The FDA or a non-US regulatory authority may require us to conduct additional clinical or preclinical testing. Success in early preclinical studies and clinical trials does not mean that future larger registration clinical trials will be successful and interim results of a clinical trial do not necessarily predict final results. Product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA and non-U.S. regulatory authorities despite having progressed through initial clinical trials. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in adherence to the dosing regimen and other clinical trial protocols and the rate of dropout among clinical trial participants. In addition, preclinical and clinical data are often susceptible to various interpretations and analyses, and many companies whose product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the pharmaceutical and biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier studies, and we cannot be certain that we will not face similar setbacks. Even if early-stage clinical trials are promising, we may need to conduct additional clinical trials of our product candidates in additional patient populations or under different treatment conditions before we are able to seek approvals from the FDA and regulatory authorities outside the United States to market and sell these product candidates. Any of these events could limit the commercial potential of our product candidates and have a material adverse effect on our business, prospects, financial condition and results of operations. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier clinical trials.

In addition, our APVO436 clinical trials are open-label studies and are conducted at a limited number of clinical sites on a limited number of patients. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved drug. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge. The results from these clinical trials may not be predictive of future clinical trial results with APVO436 or other product candidates.

We may publicly disclose top line or interim data from time to time, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. The top line or interim results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results once additional data have been received and fully evaluated. Even in situations where a clinical stage candidate appears to be benefiting a patient, that benefit may not be of a permanent nature. Top line and interim data also remain subject to audit and verification procedures, that may result in the final data being materially different from the preliminary data we previously published. In addition, the achievement of one primary endpoint for a trial does not guarantee that

additional co-primary endpoints or secondary endpoints will be achieved. Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure.

Our future clinical trials may not be successful. Moreover, should there be a flaw in a clinical trial, it may not become apparent until the clinical trial is well advanced. We may also experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including:

Further, our product candidates may not be approved even if they achieve their primary endpoints in Phase 3 clinical trials or registration trials. Regardless of any advisory committee recommendation, the FDA may decline to approve the BLA for a number of reasons including, if the clinical benefit, safety profile or effectiveness of the drug is not deemed by the FDA to warrant approval. The FDA or other non-U.S. regulatory authorities may disagree with our trial design, and our interpretation of data from non-clinical studies and clinical trials. In particular, the FDA may not view our data as being clinically meaningful or statistically persuasive. The regulatory authorities and policies governing the development of our product candidates may also change at any time. In addition, any of these regulatory authorities may change requirements for the approval of a product candidate even after reviewing and providing comments or advice on a protocol for a pivotal Phase 3 clinical trial. Any of these regulatory authorities may also approve a product candidate for fewer or more limited indications than we request or may grant approval contingent on the performance of costly post-marketing clinical

trials. The FDA or other non-U.S. regulatory authorities may not approve the labeling claims that we believe would be necessary or desirable for the successful commercialization of our product candidates.

We may not be able to file investigational new drug applications, or INDs, or IND amendments to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed.

We expect to submit an IND for ALG.APV-527 to the FDA in 2022, however, we may not be ~~called upon~~able to ~~defend ourselves against lawsuits relating~~file future INDs for our product candidates on the timelines we expect. For example, we may experience manufacturing delays or other delays with IND-enabling studies. Moreover, we cannot be sure that submission of an IND will result in the FDA allowing further clinical trials to begin, or that, once begun, issues will not arise that suspend or terminate clinical trials. Additionally, even if such regulatory authorities agree with the design and implementation of the clinical trials set forth in an IND, we cannot guarantee that such regulatory authorities will not change their requirements in the future. These considerations also apply to new clinical trials we may submit as amendments to existing INDs or to a new IND. Any failure to file INDs on the timelines we expect or to obtain regulatory approvals for our ~~business. Any litigation, regardless~~trials may prevent us from completing our clinical trials or commercializing our products on a timely basis, if at all.

If we experience delays or difficulties in the commencement, enrollment of ~~its merits,~~patients or completion of our clinical trials, the time to reach critical trial data and receipt of any necessary regulatory approvals could be delayed.

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate, enroll and maintain a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. In addition, some of our competitors have ongoing clinical trials for product candidates that treat the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates. Furthermore, APVO436 has received orphan drug designation for AML and thus has a relatively small patient population. Also, the eligibility criteria of our clinical trials may further limit the pool of available study participants as we require that patients have specific characteristics that we can measure to assure their disease is either severe enough or not too advanced to include them in a study. In addition, the global spread of the COVID-19 pandemic makes it more difficult to initiate studies and enroll patients and the process of finding and diagnosing eligible patients under these conditions may prove costly.

Our inability to enroll a sufficient number of patients for clinical trials could result in ~~substantial~~significant delays and could require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, delays in the availability of preliminary or final results, and delays to commercially launching our product candidates, if approved, which may cause the value of our company to decline and limit our ability to obtain additional financing.

Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified that could delay, prevent, or cause the withdrawal of regulatory approval, limit the commercial potential, or result in significant negative consequences following marketing approval.

Serious adverse events or undesirable side effects caused by, or other unexpected properties of any of our product candidates, either when used alone or in combination with other approved or investigational therapies, could cause us or regulatory authorities to interrupt, delay or halt our development activities and manufacturing and distribution operations and could result in a more restrictive label, the imposition of a clinical hold, suspension, distribution or use restrictions or the delay or denial of regulatory approval by the

FDA or comparable foreign regulatory authorities. If any of our product candidates are associated with serious adverse events or undesirable side effects or have properties that are unexpected, we may need to abandon their development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in clinical or earlier stage testing have later been found to cause undesirable or unexpected side effects that prevented further development of the compound.

As we continue developing our product candidates and conduct clinical trials of our product candidates, serious adverse events, or SAEs, undesirable side effects, relapse of disease or unexpected characteristics may emerge causing us to abandon these product candidates or limit their development to more narrow uses or subpopulations in which the SAEs or undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective or in which efficacy is more pronounced or durable. Undesirable side effects, or other unexpected adverse events or properties of any of our product candidates, could arise or become known either during clinical development or, if approved, after the approved product has been marketed. If such an event occurs during development, the FDA or comparable foreign regulatory authorities could suspend or terminate a clinical trial or deny approval of our product candidates. Furthermore, we may to evaluate our product candidates in combination with approved and/or experimental therapies. These combinations may have additional or more severe side effects than caused by our product candidate as monotherapies. The uncertainty resulting from the use of our product candidate in combination with other therapies may make it difficult to accurately predict side effects or efficacy in potential future clinical trials. If our product candidates receive marketing approval and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences may result, including:

Any of these events could prevent us from achieving or maintaining market approval and acceptance of the affected product candidate, or could substantially increase commercialization costs and ~~a diversion~~expenses, which could delay or prevent us from generating revenue from the sale of ~~management’s attention~~our products and materially harm our business and results of operations.

We depend on third parties to conduct our clinical and non-clinical trials. If these third parties do not effectively carry out their contractual duties, comply with regulatory requirements or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.

We do not have the ability to independently conduct the clinical and preclinical trials required to obtain regulatory approval for our product candidates. We depend on third parties, such as independent clinical investigators, contract research organizations, or CROs, and other third-party service providers to conduct the clinical and preclinical trials of our product candidates, and we expect to continue to do so. For example, Dr. Dirk Huebner, Consultant and Chief Medical Officer, is providing clinical trial and medical affairs oversight duties as an independent consultant. We rely heavily on Dr. Huebner and these other third parties for successful execution of our clinical and non-clinical trials, but we do not exercise day to day control over their activities.

While we have agreements governing the activities of third parties, we have limited influence and control over their actual performance and activities. For instance, our third-party service providers are not our employees, and except for remedies available to us under our agreements with such third parties we cannot control whether or not they devote sufficient time and resources to our ongoing clinical, and non-clinical programs. Our third-party service providers may also have relationships with other entities, some of which may be our competitors, for whom they may also be conducting trials or other therapeutic development activities that could harm our competitive position. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our non-clinical studies or clinical trials in accordance with regulatory requirements or our stated protocols, if they need to be replaced or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our protocols, regulatory requirements or for other reasons, our trials may be repeated, extended, delayed, or terminated, we may not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates, we may not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates, or we or they may be subject to regulatory enforcement actions.

Our reliance on third-party service providers does not relieve us of our regulatory responsibilities, including ensuring that our trials are conducted in accordance with the FDA-approved good clinical practices, or GCPs, and the plans and protocols contained in the relevant regulatory application. In addition, these organizations and individuals may not complete these activities on our anticipated or desired timeframe. We also may experience unexpected cost increases that are ~~needed~~beyond our control. Problems with the timeliness or quality of the work of a contract research organization may lead us to ~~successfully run~~seek to terminate the relationship and use an alternative service provider, which may prove difficult and/or costly and result in a delay of our trials. In addition, business disruptions arising from the ongoing COVID-19 pandemic could negatively affect the ability of some of the independent clinical investigators, contract research organizations and other third-party service providers that conduct our clinical and preclinical trials of our product candidates. Any delay in or inability to complete our trials could delay or prevent the development, approval, and commercialization of our product candidates.

If CROs or other third parties assisting us or our study sites fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or its non-U.S. counterparts may require us to perform additional clinical trials before approving our marketing applications. We or they may also face regulatory enforcement action. We cannot assure you that, upon inspection, the FDA or non-U.S. regulatory agencies will determine that any of our clinical trials comply with GCPs. In addition, our clinical trials must be conducted with product produced under GMPs and similar regulations outside of the United States. Our failure, or the failure of our product manufacturers, to comply with these regulations may require us to repeat or redesign clinical trials, or conduct additional trials, which would increase our development costs and delay or impact the likelihood of regulatory approval.

Agreements with third parties conducting or otherwise assisting with our clinical or non-clinical studies might terminate for a variety of reasons, including a failure to perform by the third parties. If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative providers or to do so on commercially reasonable terms. Switching or adding additional third parties involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new third party commences work. As a result, if we need to enter into alternative arrangements, it could delay our product development activities and adversely affect our business. ~~Due to~~Though we carefully manage our relationships with our third parties, there can be no assurance that we will not encounter challenges or delays in the ~~inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of any such proceedings. An unfavorable outcome in any such proceedings could~~future or that these delays or challenges will not have ana material adverse impact on our business, financial condition and prospects, and results of operations.

If any of these events occur, we may not be able to obtain regulatory approval of our product candidates or succeed in our efforts to create approved line extensions for certain of our existing products or generate additional useful clinical data in support of these products. Moreover, if we are unable to obtain any necessary third-party services on acceptable terms or if these service providers do not successfully carry out their contractual duties or meet expected deadlines, our efforts to obtain regulatory approvals for our product candidates may be delayed or prevented.

Manufacture of our product candidates, especially in large quantities, is complex and time consuming. The loss of any of our third-party manufacturers, or delays or problems in the manufacture our product candidates, could result in product shortages and/or delays in clinical development.

We do not have manufacturing capabilities and do not plan to develop such capacity in the foreseeable future. We depend on a limited number of third-party suppliers for our product candidates. Accordingly, our ability to develop and deliver products in a timely and competitive manner and to enable us to conduct our development programs depends on our third-party manufacturers being able to continue to meet our ongoing clinical trial needs and perform their contractual obligations. In order to successfully develop and commercialize our product candidates in a timely manner, we and our third-party manufacturers must be able to develop and execute on manufacturing processes and reach agreement on contract terms.

Our current and anticipated future dependence upon others for the manufacture of our product candidates or any product that we develop may adversely affect our future profit margins and our ability to commercialize any products that receive marketing approval on a timely and competitive basis. In addition, any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval.

If these third-party manufacturers do not successfully carry out their contractual duties, meet expected deadlines or manufacture our product candidates in accordance with regulatory requirements, if there are disagreements between us and such parties, or if such parties are unable to expand capacities to support commercialization of any of our product candidates for which we obtain marketing approval, we may not be able to produce, or may be delayed in producing sufficient product candidates to meet our supply requirements. Any delays in obtaining adequate supplies with respect to our product candidates and components may delay the development or commercialization of our product candidates.

We may not succeed in our efforts to establish manufacturing relationships or other alternative arrangements for any of our product candidates, components, and programs. Our product candidates may compete with other products and product candidates for access to manufacturing facilities. There are a limited number of manufacturers that operate under GMP regulations and that are both capable of manufacturing for us and willing to do so.

If our ~~stock price is volatile,~~existing third-party manufacturers, or the third parties that we engage in the future to manufacture a product or component for commercial sale or for our clinical trials should cease to continue to do so for any reason, we likely would experience delays in obtaining sufficient quantities of our product candidates for us to meet commercial demand or to advance our clinical trials while we identify and qualify replacement suppliers. These third-party facilities may also be affected by natural disasters, such as floods or fire, or such facilities could face manufacturing issues, such as contamination or regulatory findings following a regulatory inspection of such facility. In such instances, we may ~~become involved~~need to locate an appropriate replacement third-party relationship, which may not be readily available or on acceptable terms, which would cause additional delay and increased expense. In some cases, the technical skills required to manufacture our products or product candidates may be unique or proprietary to the original manufacturer and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to an alternate supplier in ~~securities class action lawsuits~~a timely fashion if at all. The addition of a new or alternative manufacturer may also require FDA approvals and may have a material adverse effect on our business.

If for any reason we are unable to obtain adequate supplies of our product candidates or the components used to manufacture them, it will be more difficult for us to develop our product candidates and compete effectively. Further, even if we do establish such collaborations or arrangements, our third-party manufacturers may breach, terminate, or not renew these agreements.

We or our third-party manufacturers may also encounter shortages in the ~~future.~~raw materials or therapeutic substances necessary to produce our product candidates in the quantities needed for our clinical trials or, if our product candidates are approved, in sufficient quantities for commercialization or to meet an increase in demand. Such shortages may occur for a variety of reasons, including capacity constraints, delays or disruptions in the market, and shortages caused by the purchase of such materials by our competitors or others. We may also not be able to obtain such materials on favorable terms as a result of global trade policies. Our or our third-party manufacturers’ failure to obtain the raw materials, therapeutic substances, or active pharmaceutical ingredients necessary to manufacture sufficient quantities of our product candidates may have a material adverse effect on our business.

All of our current product candidates are biologics. Our product candidates must be made consistently and in compliance with a clearly defined manufacturing process. Problems may arise during manufacturing for a variety of reasons, including problems with raw materials, equipment malfunction or replacement and failure to follow specific protocols and procedures. Slight deviations anywhere in the manufacturing process, including obtaining materials, maintaining master seed or cell banks and preventing genetic drift, seed or cell growth, fermentation and contamination including from, among other things, particulates, filtration, filling, labeling, packaging, storage and shipping, and quality control testing, may result in lot failures or manufacturing shut-down, delays in the release of lots, product recalls, spoilage or regulatory action. Due to the ongoing COVID-19 pandemic, our third-party manufacturers may experience difficulties that impact our product candidates.

Additionally, our development and commercialization strategy involves entering into arrangements with corporate and academic collaborators, contract research organizations, distributors, third-party manufacturers, licensors, licensees and others to conduct development work, manage or conduct our clinical trials, manufacture our product candidates and market and sell our products outside of the United States and maintaining our existing arrangements with respect to the commercialization or manufacture of our products. We may not have the expertise or the resources to conduct all of these activities for all products and product candidates on our own and, as a result, are particularly dependent on third parties in many areas. Any current or future arrangements for development and commercialization may not be successful, as the amount and timing of resources that third parties devote to developing, manufacturing, and commercializing our products candidates are not within our control. If we are not able to establish or maintain agreements relating to our product candidates in development, our results of operations and prospects would be materially and adversely affected.

Any loss of a third-party manufacturer, any delays, or problems in the manufacture of our products, or termination of any arrangements for development and commercialization of our products could have a material adverse effect on our business, operations, results of operations and financial condition. We may be required to replace our manufacturer and if this were to occur, we may incur added costs and delays in identifying and qualifying any such replacements. We may also not be able to enter into such arrangements on favorable commercial terms.

Failure of our third-party manufacturers to successfully manufacture material that conforms to our specifications and the FDA’s or foreign regulatory authorities’ strict regulatory requirements, may prevent regulatory approval of those manufacturing facilities.

We rely on third parties to manufacture all clinical trial materials for our product candidates, and we will rely on third parties to manufacture commercial supplies, if any such product candidates are ultimately approved for commercial sale. Manufacturers of our product candidates and therapeutic substances must comply with GMP requirements enforced by the FDA that are applicable to both finished products and their active components used both for clinical and commercial supply. The FDA enforces these requirements through its facilities inspection program. Our product candidates, including APVO436 and ALG.APV-527 will not be approved for

marketing by the FDA or other foreign regulatory authorities unless the FDA or their foreign equivalents also approve the facilities used by our third-party manufacturers to produce them for commercialization. If our third-party manufacturers cannot successfully manufacture material that conforms to our specifications and the FDA’s or foreign regulatory authorities’ strict regulatory requirements, the FDA or their foreign counterparts will not approve their manufacturing facilities, which would result in significant delays in obtaining FDA or foreign marketing approvals for our product candidates. If this were to occur, we may also never receive marketing approval, we may need to repeat clinical trials, we may need to undertake costly corrective actions, including product recalls, we may risk harm to subjects or patients, and we may face enforcement actions.

While we are ultimately responsible for the manufacture of our product candidates, other than through our contractual arrangements, we have little control over our manufacturers’ compliance with these regulations and standards. If the FDA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain and maintain regulatory approval for or market our product candidates, if approved. Any new manufacturers would need to either obtain or develop the necessary manufacturing know-how, and obtain the necessary equipment and materials, which may take substantial time and investment. We must also receive FDA approval for the use of any new manufacturers for commercial supply.

We and our third-party manufacturers may not be able to meet these manufacturing process requirements for any of our current product candidates, all of which have complex manufacturing processes, which make meeting these requirements even more challenging. Due to the ongoing COVID-19 pandemic, our third-party manufacturers may experience difficulties that impact our product candidates. If we are unable to develop manufacturing processes for our clinical product candidates that satisfy these requirements, we will not be able to supply sufficient quantities of test material to conduct our clinical trials in a timely or cost effective manner, and as a result, our development programs will be delayed, our financial performance will be adversely impacted and we will be unable to meet our long-term goals.

Certain of our product candidates have received orphan drug designation from the FDA. However, there is no guarantee that we will be able to maintain this designation, receive this designation for any of our other product candidates, or receive or maintain any corresponding benefits, including periods of exclusivity.

Certain of our product candidates have received orphan drug designation. We may also seek orphan drug designation for our other product candidates, as appropriate. While orphan drug designation does provide us with certain advantages, it neither shortens the development time or regulatory review time of a product candidate nor gives the product candidate any advantage in the regulatory review or approval process.

Generally, if a product candidate with orphan drug designation subsequently receives marketing approval before another product considered by the FDA to be the same for the same orphan indication, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug or biologic for the same indication for a period of seven years in the United States.

We may not be able to obtain any future orphan drug designations that we apply for. Orphan drug designations do not guarantee that we will be able to successfully develop our product candidates, and there is no guarantee that we will be able to maintain any orphan drug designations that we receive. For instance, orphan drug designations may be revoked if the FDA finds that the request for designation contained an untrue statement of material fact or omitted material information, or if the FDA finds that the product candidate was not eligible for designation at the time of the submission of the request.

Moreover, even if we are able to receive and maintain orphan drug designations, we may ultimately not receive any period of regulatory exclusivity if our product candidates are approved. For instance, we may not receive orphan product regulatory exclusivity if the indication for which we receive FDA approval is broader than the orphan drug designation. Orphan exclusivity may also be lost for the same reasons that orphan drug designation may be lost. Orphan exclusivity may further be lost if we are unable to assure a sufficient quantity of the product to meet the needs of patients with the rare disease or condition.

Even if we obtain orphan exclusivity for any of our current or future product candidates, that exclusivity may not effectively protect the product from competition as different products can be approved for the same condition or products that are the same as ours can be approved for different conditions. Even after an orphan product is approved, the FDA can also subsequently approve a product containing the same principal molecular features for the same condition if the FDA concludes that the later product is clinically superior. The FDA may further grant orphan drug designation to multiple sponsors for the same compound or active molecule and for the same indication. If another sponsor receives FDA approval for such product before we do, we would be prevented from launching our product in the United States for the orphan indication for a period of at least seven years, unless we can demonstrate clinical superiority. Moreover, third-party payors may reimburse for products off-label even if not indicated for the orphan condition.

We have in the past and may in the future conduct clinical trials for our product candidates outside the United States, and the FDA or non-U.S. regulatory authorities may not accept data from such trials in the development or approval of our product candidates in those jurisdictions.

We have in the past and may in the future conduct clinical trials outside the U.S. and the FDA and foreign regulatory authorities may not accept those data in support of the further development or approval of our product candidates. The acceptance of trial data from clinical trials conducted outside the United States by the FDA or applicable foreign regulatory authority may be subject to certain conditions. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the United States population and United States medical practice; and (ii) the trials were performed by clinical investigators of recognized competence and pursuant to GCP regulations. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements.

In addition, such foreign trials will be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any applicable foreign regulatory authority will accept data from trials conducted outside of the United States. If the FDA or any applicable foreign regulatory authority does not accept such data, it would result in the need to conduct additional trials beyond those we have planned, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving marketing approval for commercialization in the applicable jurisdiction.

Our ability to grow revenues and execute on our long-term strategy depends heavily on our ability to discover, develop, and obtain marketing approval for ~~additional products or~~our product candidates.

We currently have no products approved for commercial distribution. We have invested a significant portion of our efforts and financial resources in the development of our product candidates. Our business depends on the successful development and commercialization of our product candidates, which will require additional clinical and preclinical development, regulatory approval, commercial manufacturing arrangements, establishment of a commercial organization, significant marketing efforts, and further investment, which may never occur. Our ability to generate revenues is substantially dependent on our ability to develop, obtain regulatory approval for, and then successfully commercialize our product candidates. Except for the revenues from previously sold products, we currently generate no revenues from sales of any products, and we may never be able to develop or commercialize a marketable product.

In order for us to achieve our long-term business objectives, we will need to successfully discover and/or develop and commercialize ~~additional products or~~our product candidates. Although we have made, and expect to continue to make, significant investments in research and development, we have had only a limited number of our internally-discovered product candidates reach the clinical development stage. We currently have one clinical-stage candidate, APVO436, which is built on the ADAPTIR platform. Drug discovery and development is a complex, time-consuming and expensive process that is fraught with risk and a high rate of failure. Our product candidates are susceptible to the risks of failure inherent at any stage of product development, including the appearance of unexpected or unacceptable adverse events or failure to demonstrate efficacy in clinical trials. For example, in 2018, we announced the discontinuation of development of APVO414 and otlertuzumab as a result of clinical trial results. In addition, in October 2019, we announced our decision to discontinue development of APVO210, a novel investigational bispecific antibody candidate under development for the treatment of autoimmune diseases. The decision followed the review of data from Phase 1 multiple ascending dose (MAD) clinical study of APVO210 in healthy volunteers that suggests that APVO210 would not meet the desired target product profile for future commercialization. Specifically, the clinical data showed evidence of increasing titers of ADA with repeated doses of APVO210, which had varying impact on APVO210 drug levels in subjects’ blood. Failure to successfully discover and/or develop, obtain marketing approval for and commercialize additional products and product candidates would likely have a material adverse effect on our ability to grow revenues and improve our financial condition. If we are required to conduct additional clinical trials or other testing of our product candidates that we develop beyond those that we currently expect, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive, or if there are safety concerns, we may be delayed in obtaining marketing approval for our product candidates, not obtain marketing approval at all, obtain approval for limited indications or patient populations, with a label without claims necessary for us to successfully market our products, or with significant labeled warnings. We may also be subject to additional post-marketing testing requirements, surveillance requirements, or REMS. To the extent any of the foregoing should occur, our business may be materially harmed.

We may not be successful in our efforts to use and further develop our ADAPTIR ~~platform.~~or ADAPTIR-FLEX platforms.

A key element of our strategy is to expand our product pipeline of immunotherapeutics based on our ADAPTIR and ADAPTIR-FLEX platform ~~technology.~~technologies. We plan to select and create product candidates for early development, potentially with other collaborative partners. We expect to continue to develop the platform to address unmet medical needs through directed cytokine delivery via monospecifics and bispecifics in areas including oncology, and ~~multispecific~~multi-specific molecules in oncology ~~autoimmune disease~~ and other therapeutic areas. Our

goal is to leverage this technology to make targeted investment in monospecific, bispecific, and multi-specific ADAPTIR and ADAPTIR-FLEX therapeutics. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable for clinical development, including as a result of being shown to have harmful side effects or other characteristics that indicate that they are unlikely to be products that will receive marketing approval and achieve market acceptance. If we do not successfully develop and commercialize product candidates based on our ADAPTIR and ADAPTIR-FLEX platform ~~technology,~~technologies, our ability to obtain product revenues in future periods may be adversely affected, which likely would result in harm to our financial position and our financial prospects, and adversely affect our stock price.

We face and will continue to face substantial ~~competition.~~competition and our failure to effectively compete may prevent us from achieving significant market penetration for our product candidates, if approved.

The development and commercialization of new biotechnology products is highly competitive and subject to rapid technological advances. We may face future competition with respect to ~~IXINITY,~~ our current product candidates and any product candidates we may seek to develop or commercialize in the future obtained from other companies and governments, universities, and other non-profit research organizations. Our competitors may develop products that are safer, more effective, more convenient, or less costly than any products that we may develop or market, or may obtain marketing approval for their products from the ~~U.S. Food and Drug Administration, or the~~ FDA, or equivalent foreign regulatory bodies more rapidly than we may obtain approval for our ~~products.~~product candidates. Our competitors may have greater resources and may devote greater resources to ~~market or sell~~research and develop their products, research and development capabilities, adapt more quickly to new technologies, scientific advances or patient preferences and needs, initiate or withstand substantial price competition more successfully, or more effectively negotiate third-party licensing and collaborative arrangements.

We believe that our most significant competitors in the ~~hematology/~~oncology ~~inflammation and transplantation markets~~market include: AbbVie Inc., ~~Affirmed,~~Affimed, Amgen Inc., AnaptysBio, Inc., Astellas Pharma ~~Inc., Baxalta US~~ Inc., Bayer AG, Biogen Idec Inc., Boehringer Ingelheim GmbH, ~~CSL Behring, a subsidiary of CSL Limited, Dendron Corp.~~Cellectis, Chinook Therapeutics, F-Star Biotechnology Ltd., Genentech Inc. (a subsidiary of F. Hoffmann-La Roche Ltd.), Genmab A/S, ~~Gilead Sciences, Inc.,~~ GlaxoSmithKline plc, Grifols USA LLC, Bristol Myers Squibb, ImmunoGen, Inc., Immunomedics, Inc., Janssen BioTech Inc., Johnson & Johnson, Macrogenics, Inc., ~~Novartis International AG, Pfizer~~Pieris Pharmaceuticals, Inc., ~~Sanofi-Adventis~~Sanofi-Aventis US LLC, Takeda Pharmaceuticals U.S.A., Inc., Xencor, Inc. and Zymeworks Biopharmaceuticals, Inc. We ~~compete, in the case of IXINITY, and~~ expect to compete ~~in the cases of our product candidates in development,~~ on the basis of product efficacy, safety, ease of administration, price and economic value compared to drugs used in current practice or currently being developed. If we are not successful in demonstrating these attributes, physicians and other key healthcare decision makers may choose other products over ~~our~~any products we successfully develop, switch from our products to new products or choose to use our products only in limited circumstances, which could adversely affect our business, financial condition and results of operations.

In addition, many of our competitors are able to deploy more personnel to market and sell their products than we do. We currently have a relatively small number of sales representatives compared with the number of sales representatives of most other biotechnology companies with marketed products. Each of our sales representatives is responsible for a territory of significant size. The continued growth of IXINITY and the launch of any future products may require expansion of our sales force and sales support organization internationally, and we may need to commit significant additional funds, management and other resources to the growth of our sales organization. We may not be able to achieve any necessary growth in a timely or cost-effective manner or realize a positive return on our investment, and we may not have the financial resources to achieve the necessary growth in a timely manner or at all. We also have to compete with other biotechnology and life sciences companies to recruit, hire, train and retain sales and marketing personnel, and turnover in our sales force and marketing personnel could negatively affect sales IXINITY. If our specialty sales force and sales organization are not appropriately-sized to adequately promote any current or potential future products, the commercial potential of IXINITY and any future products may be diminished. We compete with a significant number of pharmaceutical and life sciences companies with extensive sales, marketing and promotional experience in the hematology/oncology markets, and our failure to compete effectively in this area could negatively affect our sales of IXINITY.

~~IXINITY and our product candidates may also compete in the future with new products currently under development by others.~~ Any products that we develop are likely to be in a highly competitive market, and many of our competitors may succeed in developing products before we do or in developing products that may render our products obsolete or noncompetitive.

Competition for IXINITY, may be affected by follow-on biologics, or biosimilars, in the United States and other jurisdictions. Biologics are medical products made from a variety of natural sources (human, animal or microorganism) intended to prevent, diagnose or treat diseases and medical conditions.

In the United States, biosimilars are biologics that are highly similar to licensed reference biological products, notwithstanding minor differences in clinically inactive components, and for which there are no clinically meaningful differences between the biosimilar and the reference product in terms of safety, purity and potency. Regulatory and legislative activity in the United States and other countries may make it easier for our competitors to manufacture and sell biosimilars of IXINITY, which might affect our results of operations or commercial viability of our IXINITY. Under the Biologics Price Competition and Innovation Act of 2010, the FDA cannot approve an application for a biosimilar until the 12-year exclusivity period for the reference product has expired. Thus, if a competitor were to seek regulatory approval for a biosimilar product citing IXINITY as the reference product, such approval could not be granted until April 2027.

Regulators in the EU review biosimilar products using a similar regulatory process. IXINITY has not received marketing authorization by the European Medicines Agency, or EMA, and is not sold in Europe.

~~If a biosimilar version of IXINTY is approved, it could have a material adverse effect on the sales and gross profits of IXINTY and could adversely affect our business and operating results.~~

~~The commercial success of IXINITY and any~~ of our product candidates, ~~will depend upon the degree of market acceptance by physicians, patients,~~if approved, may become subject to unfavorable pricing regulations or third-party ~~payors~~coverage and ~~others in the medical community.~~reimbursement policies, which would harm our business.

The success of ~~IXINITY and~~ our product candidates, if approved, will depend upon, among other things, their acceptance by physicians, patients, third-party payors, and other members of the medical community as a therapeutic and cost-effective alternative to competing products and treatments. If ~~IXINITY or~~ any of our product candidates do not achieve and maintain an adequate level of acceptance, we may not generate material revenues from sales of these products. The degree of market acceptance of our products will depend on a number of factors, including: our ability to provide acceptable evidence of safety and efficacy; the prevalence and severity of any side effects; availability, relative cost and relative efficacy of alternative and competing treatments; the ability to offer our products for sale at competitive prices; our ability to continuously supply the market without interruption; the relative convenience and ease of administration; the willingness of the target patient population to try new products and of physicians to prescribe these products; the strength of marketing and distribution support; publicity concerning our products or competing products and treatments; and the sufficiency of coverage or reimbursement by third parties.

~~If IXINITY and our product candidates do not gain~~Legislative or ~~maintain market acceptance, or do not become widely accepted, by physicians, patients, third-party payors and other members of the medical community,~~healthcare reform measures may have a material adverse effect on our business ~~financial condition~~ and ~~operating~~ results ~~could be materially and adversely affected.~~of operations.

~~Changes in health care systems and payor reimbursement policies could result in a decline in our potential sales and a reduction in our expected revenue from IXINITY and our product candidates.~~

The revenues and profitability of biotechnology companies like ours may be affected by the continuing efforts of government payors, including Medicare and Medicaid, and other third-party payors to contain or reduce the costs of health care through various means. For example, in certain foreign markets, the pricing or profitability of therapeutic and other pharmaceutical products is subject to governmental control. In the United States, there have been and ~~we expect that there will~~ continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the ACA was enacted, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. However, some provisions of the ACA have yet to be fully implemented and certain provisions have been subject to legal and political challenges, as well as efforts to repeal, replace delay, circumvent, or loosen certain aspects of the ACA or mandates required thereby. Additionally, Congress has considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA, such as removing penalties as of January 1, 2019 for not complying with the ACA’s individual mandate to carry health insurance, delaying the implementation of certain ACA-mandated fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. It is unclear how other healthcare reform measures of the Biden administration or other efforts, if any, to

challenge, repeal or replace the ACA will impact our business. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted:

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011 among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of 2 percent per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030 unless additional Congressional action is taken.

Additionally, there has been heightened governmental scrutiny recently over the manner in which manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries and proposed and enacted federal and state ~~proposals~~legislation designed to, ~~implement similar governmental control. Recent U.S. legislation, rules~~among other things, bring more transparency to drug pricing, review the relationship between pricing and ~~regulations instituted significant changes~~manufacturer patient programs, and reform government program reimbursement methodologies for drug products, including by tying reimbursement to the price of products in other developed countries. For example, proposals have been made to increase drug manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products, and reduce the out-of-pocket costs of drug products paid by consumers. Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. On January 20, 2021, Joe Biden was sworn in as the U.S. president, and the Democratic Party obtained an equal number of seats in the U.S. Senate as the Republican Party, as well as maintained control of the U.S. House of Representatives. Many expect that the Biden administration will pursue stronger healthcare ~~system that~~consumer protections, and it may act to overturn some of the prior Trump administration initiatives; however, the legislative and regulatory agendas, as they relate to the healthcare and pharmaceutical industries and the economy as a whole, of the Biden administration and the U.S. Congress currently remain uncertain. Any new laws and initiatives may result in additional reductions in Medicare and other healthcare funding or impose additional regulatory requirements on drug development or approval, which could have a material adverse effect on our ~~business,~~future customers and accordingly, our financial ~~condition~~operations.

We expect that additional state and ~~results of operations. The trend toward managed health care~~federal healthcare reform measures will be adopted in the ~~United States, as well as~~future, any of which could limit the ~~implementation of the Patient Protection~~amounts that federal and ~~Affordable Care Act (as amended by the Health Care~~state governments will pay for healthcare products and Education Reconciliation Act), collectively referred to as the Affordable Care Act, and the concurrent growth of organizations such as managed care organizations, accountable care organizations and integrated delivery networks,services, which could result in reduced demand for any product candidates we successfully develop or additional pricing pressures.

Changes in product candidate manufacturing or formulation may result in ~~increased pricing pressures for pharmaceutical products, including any products~~additional costs or delay.

As product candidates are developed through preclinical studies to late-stage clinical trials toward approval and commercialization, it is common that ~~may be offered by us~~various aspects of the development program, such as manufacturing methods, manufacturing sites, and formulation, are altered along the way in ~~the future. Cost-cutting measures that health care providers are instituting,~~an effort to optimize processes and ~~the implementation~~results. Any of ~~health care reform,~~these changes could ~~adversely affect our ability to sell any drug products that are successfully developed by us. We cannot predict what effects, if any, this legislation might have on our company and IXINITY and~~cause our product candidates ~~as this legislation continues~~ to ~~be further implemented over the next few years, nor can we predict whether additional legislative or regulatory proposals may be adopted.~~

~~In the United States~~perform differently and internationally, sales of IXINITY and our ability to generate revenues on such sales are dependent, in significant part, on the availability and level of reimbursement from third-party payors, including state and federal governments and private insurance plans. Insurers have implemented cost-cutting measures and other initiatives to enforce more stringent reimbursement standards and likely will continue to do so in the future. These measures include the establishment of more restrictive formularies and increases in the out-of-pocket obligations of patients for such products. Third-party payors are also increasingly challenging the prices charged for medical products and services. Third-party payors may limit access to biotechnology products through the use of prior authorizations and step therapy. Any reimbursement granted may not be maintained, or limits on reimbursement available from third parties, may reduce the demand for or negatively affect the ~~price and potential profitability~~results of ~~those products. If these payors do not provide sufficient coverage and reimbursement for IXINITY~~planned clinical trials or ~~any~~other future ~~drug product we~~clinical trials conducted with the altered materials. Such changes may market, these products may be too costly for general use, and physicians may prescribe them less frequently. Our ability to successfully commercialize our products and product candidates and the demand for our products depends, in part, on the extent to which reimbursement and access is available from such third-party payors.

In addition, particularly in the United States and increasingly in other countries, we are required to provide discounts and pay rebates to state and federal governments and agencies in connection with purchases IXINITY that are reimbursed by such entities. Various provisionsalso require additional testing, clinical trials, FDA notification, or FDA approval. Any of the ~~Affordable Care Act increased the levels of rebates~~foregoing could limit our future revenues and discounts that we have to provide in connection with sales of IXINITY that are paid for, or reimbursed by, certain state and federal government agencies and programs. It is possible that future legislation and regulatory changes in the United States and other jurisdictions could be enacted, which could potentially impact the reimbursement rates for IXINITY and also could further impact the levels of discounts and rebates we are required to pay to state and federal government entities.growth.

Certain government pricing programs, including Medicare Part B, the Medicaid rebate program, the 340B/PHS drug pricing program and Federal Supply Schedule, affect the revenues that we derive from IXINITY and product candidates. Any future legislation or regulatory actions altering these programs or imposing new ones could have an adverse impact on our business. There have been, and we expect there will continue to be, a number of legislative and regulatory actions and proposals to control and reduce health care costs. These measures may, among other things: negatively impact the level of reimbursement for pharmaceutical products; require higher levels of cost-sharing by beneficiaries; change the discounts required to be provided to government payors and/or providers; extend government discounts to additional government programs and/or providers; or reduce the level of reimbursement for health care services and other non-drug items. Any such measures could indirectly affect demand for pharmaceutical products because they can cause payors and providers to apply heightened scrutiny and/or austerity actions to their entire operations, including pharmacy budgets.

~~Our revenues also depend on the availability outside the United States of adequate pricing and reimbursement from third-party payors for IXINITY and future drug products, if any.~~

Outside the United States, certain countries, including a number of EU Member States, set prices and reimbursement for pharmaceutical products, or medicinal products as they are commonly referred to in the EU, with limited participation from the marketing authorization holders. We cannot be sure that these prices and reimbursement will be acceptable to us or our collaborative partners. If the regulatory authorities in these foreign jurisdictions set prices or reimbursement that are not commercially attractive for us or our collaborative partners, our revenues from sales, and the potential profitability of our drug products, in those countries would be negatively affected. An increasing number of countries are taking initiatives to attempt to reduce large budget deficits by focusing cost-cutting efforts on pharmaceuticals for their state-run health care systems. These international price control efforts have impacted all regions of the world, but have been most drastic in the EU.

~~An inability to convince hospitals and managed care organizations to include IXINITY on their approved formulary lists, may result in our failure to meet revenue expectations.~~

Hospitals and managed care organizations establish formularies, which are lists of drugs approved for use in the hospital or under a managed care plan. If a drug is not included on the formulary, the ability of our engagement partners and engagement managers to promote and sell the drug may be limited or denied. If we fail to secure and maintain formulary inclusion for IXINITY on favorable terms or are significantly delayed in doing so, we may have difficulty achieving market acceptance of IXINITY and our business, results of operations and financial condition could be materially adversely affected.

~~If we are unable to negotiate and maintain satisfactory arrangements with group purchasing organizations our financial condition could be adversely affected.~~

Our ability to sell IXINITY, to hospitals and clinics in the United States depends in part on our relationships with group purchasing organizations, or GPOs. GPOs negotiate pricing arrangements and contracts, sometimes on an exclusive basis, with medical supply manufacturers and distributors. These negotiated prices are then made available to a GPO’s affiliated hospitals and clinics and other members. If we are not one of the providers selected by a GPO, affiliated hospitals, clinics and other members may be less likely to purchase IXINITY, and if the GPO has negotiated a strict sole source, market share compliance or bundling contract for another manufacturer’s products, we may be precluded from making sales to members of the GPO for the duration of the contractual arrangement. Our failure to renew contracts with GPOs may cause us to lose market share and could have a material adverse effect on our sales, financial condition and results of operations. We cannot assure you that we will be able to renew these contracts on the current or substantially similar terms. If we are unable to keep our relationships and develop new relationships with GPOs, our competitive position may suffer.

~~We rely on third parties to distribute~~ ~~IXINITY~~ ~~and those third parties may not perform.~~

We rely on the sales and marketing strength of these distributors and the distribution channels through which they operate for a portion of our revenues. If third parties do not successfully carry out their contractual duties, or if there is a delay or interruption in the distribution of our products, it could negatively impact our revenues from product sales.

~~The loss of any of our sole source manufacturers, or delays or problems in the manufacture of~~ ~~IXINITY~~ ~~or our product candidates, could result in product shortages and loss in revenue or delays in clinical development.~~

We do not have manufacturing capabilities and do not plan to develop such capacity in the foreseeable future. We depend on a limited number of sole source third-party manufacturers, including CMC ICOS Biologics, Inc., for our products and product candidates. Accordingly, our ability to develop and deliver products in a timely and competitive manner depend on our third-party manufacturers being able to continue to meet our ongoing commercial and clinical trial needs and perform their contractual obligations. We have a limited ability to control the manufacturing process or costs related to the manufacture of IXINITY and our product candidates. Increases in the prices we pay our manufacturers, interruptions in the supply of raw materials or IXINITY themselves or lapses in quality could adversely impact our margins, profitability, cash flows and prospects.

If, for any reason, CMC, sole manufacturer of bulk drug substance for our IXINITY product, does not continue to supply us with IXINITY in a timely fashion and in compliance with applicable quality and regulatory requirements, or otherwise fails or refuses to comply with its obligations to us under our manufacturing arrangement, we may not have adequate remedies for any breach of contract, and its failure to supply us could result in a shortage of IXINITY, which could lead to lost revenue and otherwise adversely affect our business, financial condition, results of operations and growth prospects. In addition, if CMC fails or refuses to supply us for any reason, we may be forced to consider entering into additional manufacturing arrangements with other third-party manufacturers. In each case, we will incur significant costs and time in obtaining the regulatory approvals for these third-party facilities and in taking the necessary steps to prepare these third parties for the manufacture of IXINITY. Because of contractual restraints and the lead-time necessary to obtain FDA approval of a new manufacturer, replacement of any of these manufacturers may be expensive and time consuming and may cause interruptions in our supply of IXINITY to our customers or an inability to manufacture.

For example, during 2015, we ordered nine manufacturing lots of bulk drug substance from CMC and only one of those lots was successfully manufactured and released in 2015. During 2016, we ordered five manufacturing lots of bulk drug substance from CMC and none of these lots satisfied product release specifications.

In accordance with the Restated Supply Agreement, a $7.0 million reserve held by CMC will be will be applied to, at a minimum, the next four batches manufactured through the end of 2017 as a price concession in the form of no raw materials or other related costs associated with the inventory. As this reserve is utilized, Aptevo will also see an impact on the Company’s income statement due to a lower costs of goods sold associated with this inventory, which will also result in higher gross margins as sales are recognized. Any remaining reserve amount outstanding as of December 25, 2017 shall be paid to the Company on or before December 31, 2017. The Restated Supply Agreement has a five-year term renewable with twenty-four months’ prior notice before the expiry of the term for successive two-year terms.

While we do not currently anticipate or foresee a supply shortage or supply interruption occurring, any supply shortage or supply interruption of IXINITY would adversely affect its sales and could adversely affect its market position, commercial viability and the trading price of our common stock.

~~Manufacturing biologic products, especially in large quantities, is complex and time consuming.~~

IXINITY and all of our current product candidates are biologics. IXINITY and our product candidates must be made consistently and in compliance with a clearly defined manufacturing process. Problems may arise during manufacturing for a variety of reasons, including problems with raw materials, equipment malfunction or replacement and failure to follow specific protocols and procedures. Slight deviations anywhere in the manufacturing process, including obtaining materials, maintaining master seed or cell banks and preventing genetic drift, seed or cell growth, fermentation and contamination including from, among other things, particulates, filtration, filling, labeling, packaging, storage and shipping, and quality control testing, may result in lot failures or manufacturing shut-down, delays in the release of lots, product recalls, spoilage or regulatory action.

We rely on third parties to manufacture all clinical trial materials for our product candidates, and we will rely on third parties to manufacture commercial supplies, if any such product candidates are ultimately approved for commercial sale. Our product candidates, including APVO414, APVO210, otlertuzumab, APVO436 and ALG.APV-527, will not be approved for marketing by the FDA or other foreign regulatory authorities unless the FDA or their foreign equivalents also approve the facilities used by our third-party manufacturers to produce them for commercialization. If our third-party manufacturers cannot successfully manufacture material that conforms to our specifications and the FDA’s or foreign regulatory authorities’ strict regulatory requirements, the FDA or their foreign counterparts will not approve their manufacturing facilities, which would result in significant delays in obtaining FDA or foreign marketing approvals for our product candidates. In order to successfully develop and commercialize our product candidates in a timely manner, we and our third-party manufacturers must be able to develop and execute on manufacturing processes, and reach agreement on contract terms.

We and our third-party manufacturers may not be able to meet these manufacturing process requirements for any of our current product candidates, all of which have complex manufacturing processes, which make meeting these requirements even more challenging. If we are unable to develop manufacturing processes for our clinical product candidates that satisfy these requirements, we will not be able to supply sufficient quantities of test material to conduct our clinical trials in a timely or cost effective manner, and as a result, our development programs will be delayed, our financial performance will be adversely impacted and we will be unable to meet our long-term goals.

~~Development and commercialization of IXINITY and our product candidates may be terminated or delayed.~~

Our development and commercialization strategy involves entering into arrangements with corporate and academic collaborators, contract research organizations, distributors, third-party manufacturers, licensors, licensees and others to conduct development work, manage or conduct our clinical trials, manufacture IXINITY and our product candidates and market and sell our products outside of the United States and maintaining our existing arrangements with respect to the commercialization or manufacture of our products. We may not have the expertise or the resources to conduct all of these activities for all products and product candidates on our own and, as a result, are particularly dependent on third parties in many areas. Any current or future arrangements for development and commercialization may not be successful. If we are not able to establish or maintain agreements relating to IXINITY and our product candidates in development, our results of operations would be materially and adversely affected.

Third parties may not perform their contractual obligations as expected. The amount and timing of resources that third parties devote to developing, manufacturing and commercializing our products candidates are not within our control. Our collaborative partners may develop, manufacture or commercialize, either independently or with others, products and services that are similar to or competitive with the products that are the subject of the collaboration with us. Furthermore, our interests may differ from those of third parties that manufacture or commercialize our products. Our collaborative partners may reevaluate their priorities from time to time, including following mergers and consolidations, and change the focus of their development, manufacturing or commercialization efforts. Disagreements that may arise with these third parties could delay or lead to the termination of the development or commercialization of our product candidates, or result in litigation or arbitration, which would be time consuming and expensive.

If any third-party that manufactures or supports the development or commercialization of IXINITY and our product candidates breaches or terminates its agreement with us, or fails to commit sufficient resources to our collaboration or conduct its activities in a timely manner, or fails to comply with regulatory requirements, such breach, termination or failure could delay or otherwise adversely impact the manufacturing, development or commercialization of IXINITY, our products in development or any additional products or product candidates that we may develop; require us to seek a new collaborator or undertake unforeseen additional responsibilities or devote unforeseen additional resources to the manufacturing, development or commercialization IXINITY and our product candidates; or result in the termination of the development or commercialization of IXINITY and our product candidates.

~~If we are unable to successfully develop our business infrastructure and operations, our ability to generate future product revenue will be adversely affected.~~

To manage our existing and planned future growth, including our ability to support the sales and marketing of IXINITY and our product candidates in the United States and globally, and the increasing breadth and complexity of our activities, we need to properly invest in personnel, infrastructure, information management systems and other operational resources. Developing our business infrastructure and operations may be more difficult, more expensive or take longer than we anticipate. We may also need to revise our strategy for developing the proper infrastructure and operations periodically.

~~We are subject to a number of risks and uncertainties associated with our international activities and operations.~~

We currently have limited operations outside of the United States. However, we have manufacturing, collaboration, clinical trial and other relationships outside the United States, and our products are marketed internationally through collaborations. We may seek to grow our international operations significantly over the next several years. Our future results of operations will depend in part on our ability to grow our product sales in foreign markets, particularly in Europe. Our foreign operations subject us to additional risks and uncertainties, particularly because we have limited experience in marketing, servicing and distributing our products or otherwise operating our business outside of the United States and Canada. These risks and uncertainties include: political and economic determinations that adversely impact pricing or reimbursement policies; our customers’ ability to obtain reimbursement for procedures using our products in foreign markets; export licensing requirements, political and economic instability, trade restrictions, and changes in tariffs and difficulties in staffing and managing foreign operations; cross border restrictions on the movement of cash funds and repatriation of earnings; foreign currency fluctuations; longer accounts receivable collection times; reduced protection of intellectual property rights in some foreign countries; the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute; and compliance with foreign or U.S. laws, rules and regulations, including data privacy requirements, labor relations laws, tax laws, anti-competition regulations, anti-bribery/anti-corruption laws, including but not limited to the U.S. Foreign Corrupt Practices Act, or FCPA, and the U.K. Bribery Act of 2010, which could subject us to investigation or prosecution under such U.S. or foreign laws.

Our ~~long term~~long-term success depends, in part, upon our ability to develop, receive regulatory approval for and commercialize our product candidates.

Our product candidates and the activities associated with their development, including testing, manufacture, recordkeeping, storage, and approval, are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries. ~~Generally, failure~~Failure to obtain regulatory approval for a product candidate will prevent us from commercializing the product candidate. We have limited resources for use in preparing, filing, and supporting the applications necessary to gain regulatory approvals and expect to rely on third-party contract research organizations and consultants to assist us in this process.

The FDA and other comparable regulatory agencies in foreign countries impose substantial and rigorous requirements for the development, production, marketing authorization and commercial introduction of drug products. These requirements include ~~preclinical,~~non-clinical, laboratory and clinical testing procedures, sampling activities, clinical trials, and other costly and time-consuming procedures. In addition, regulation is not static, and regulatory authorities, including the FDA evolve in their staff interpretations and practices and may impose more stringent or different requirements than currently in effect, which may adversely affect our planned and ongoing drug development and/or our sales and marketing efforts.

In the United States, to obtain approval from the FDA to market any of our future biologic products, we will be required to submit a ~~biologics license application, or~~ BLA to the FDA. Ordinarily, the FDA requires a sponsor to support a BLA with substantial evidence of the product’s safety, purity, and potency in treating the targeted indication based on data derived from adequate and well-controlled clinical trials, including Phase ~~III~~3 safety and efficacy trials conducted in patients with the disease or condition being targeted.

The process of obtaining these regulatory approvals is expensive, often takes many years if approval is obtained at all, and can vary substantially based upon the type, complexity and novelty of the product candidate involved. Changes in the regulatory approval process during the development period, changes in or the enactment of additional statutes or regulations, or changes in the regulatory review for a submitted product application may cause delays in the approval or rejection of an application.

The FDA has substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient to support approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent regulatory approval of a product candidate.

~~We have a pipeline of clinical and preclinical stage product candidates, including:~~

Developing and obtaining regulatory approval for product candidates is a lengthy process, often taking a number of years, is uncertain and is expensive. All of the product candidates that we are developing, or may develop in the future, require research and development, ~~preclinical~~non-clinical studies, ~~nonclinical~~non-clinical testing, and clinical trials prior to seeking regulatory approval, and commencing commercial sales. In addition, we may need to address a number of technological challenges in order to complete development of our product candidates. As a result, the development of product candidates may take longer than anticipated or not be successful at all.

Our product candidate development costs will also increase if we experience delays in testing or approvals, and we may not have sufficient funding to complete the testing and approval process for any of our product candidates. We may be required to obtain additional funds to complete clinical trials and prepare for possible commercialization of our product candidates. We do not know whether any non-clinical tests or clinical trials above what we currently have planned will be required, will begin as planned, will need to be restructured, or will be completed on schedule, or at all. Significant delays relating to any preclinical or clinical trials also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do. This may prevent us from receiving marketing approvals and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations. In addition, many of the factors that cause, or lead to, delays in clinical trials may ultimately lead to the denial of marketing approval of any of our product candidates. If any of this occurs, our business, financial condition, results of operations, and prospects will be materially harmed.

Generally, no product can receive FDA approval, marketing authorization from the European Commission or the competent authorities of the EU Member States, or approval from comparable regulatory agencies in foreign countries unless data generated in human clinical trials demonstrates both safety and efficacy for each target indication in accordance with such authority’s standards.

The large majority of product candidates that begin human clinical trials fail to demonstrate the required safety and efficacy characteristics necessary for marketing approval. Failure to demonstrate the safety and efficacy of any of our product candidates for each target indication in clinical trials would prevent us from obtaining required approvals from regulatory authorities, which would prevent us from commercializing those product candidates. Negative or inconclusive results from the clinical trials or adverse medical events during the trials could lead to requirements that trials be repeated or extended, or that additional trials be conducted, any of which may not be clinically feasible or financially practicable, that the conduct of trials be suspended, or that a program be terminated.

Any regulatory approval we ultimately obtain may limit the indicated uses for the product or subject the product to restrictions or post-approval commitments that render the product commercially non-viable. Securing regulatory approval requires the submission of extensive non-clinical and clinical data, information about product manufacturing processes and inspection of facilities and supporting information to the regulatory authorities for each therapeutic indication to establish the product’s safety and efficacy. If we are unable to submit the necessary data and information, for example, because the results of clinical trials are not favorable, or if the applicable regulatory authority delays reviewing or does not approve our applications, we will be unable to obtain regulatory approval.

Delays in obtaining or failure to obtain regulatory approvals may: delay or prevent the successful commercialization of any of the products or product candidates in the jurisdiction for which approval is sought; diminish our competitive advantage; and defer or decrease our receipt of revenue.

~~Certain~~Some of our ~~products~~product candidates previously in development ~~have~~ experienced regulatory and/or clinical ~~setbacks~~setbacks. Clinical development has been discontinued for product candidates otlertuzumab, APVO414, and APVO210. Both APVO414 and APVO210 were discontinued after patients developed ADA. Most recently, in 2019, we elected to discontinue the ~~past. For example, in December 2015, after a joint~~APVO210 development program following the review of data from the Phase 1 multiple ascending dose ~~escalation~~(MAD) clinical study of ~~APVO414~~APVO210 in ~~prostate cancer patients, Aptevo and MorphoSys concluded~~healthy volunteers that suggests that APVO210 would not meet the ~~dosing regimen and administration required adjustment. Patients receiving weekly~~desired target product profile for future commercialization. Specifically, the clinical data showed evidence of increasing titers of ADA with repeated doses of ~~APVO414 developed antibodies against~~APVO210, which had varying impact on APVO210 drug levels in subjects’ blood. The cause of the ~~drug; which are called anti-drug antibodies, or ADA.~~ ADA ~~developed in most patients including those receiving the maximum tolerated dose~~is uncertain; however, we believe that appearance of drug that could be given safely on a weekly basis. These antibodies bind to the drug and reduce the concentration of active APVO414 in the blood and thus could potentially reduce its efficacy. However, we observed no safety issuesADA is related to the ~~development~~mechanism of ~~ADA. The cause~~action of ~~these antibodies is unclear but could be~~APVO210, and not due to the ~~weekly administration~~structure, or sequences characteristic of the ~~drug. Hence,~~ADAPTIR platform. Although we have re-designed certain components of the ~~protocol has been amended to continuous intravenous infusion as a way to administer higher levels of drug and prevent the development of ADA. There~~ADAPTIR platform based on what we have learned in prior clinical trials, there is no guarantee that ~~this change~~the occurrence of ADA or other clinical setbacks will not occur in ~~administration will enable higher dosing and/or prevent~~ the development of ADA. The procedures to obtain marketing approvals vary among countries and can involve additional clinical trials or other pre-filing requirements. The time required to obtain foreign regulatory approval may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all the risks associated with obtaining FDA approval, or different or additional risks. Regulatory agencies may have varying interpretations of the same data, and approval by one regulatory authority does not ensure approval by regulatory authorities in other jurisdictions. Accordingly, approval by the FDA does not ensure approval by the regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by the FDA or regulatory authorities in other foreign countries. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our ~~products and products in development in any market on a timely basis, if at all.~~

The APVO414 Phase I clinical trial under the amended protocol, providing continuous intravenous infusion as a way to administer higher levels of drug and prevent the development of ADA, commenced December 2016. As a result of the required dosing regimen change and the impact to the overall development timeline and technical risk, our co-development agreement with MorphoSys was restructured. Under the terms of the restructured agreement, MorphoSys’ cost sharing in the years 2016 to 2018 was reducedexisting and future milestone payments payable by MorphoSys to us were reduced to a total of up to $74.0 million. As a result of the required change in dosing regimen for APVO414, the lead RTCC candidate, the termination provisions under the MorphoSys collaboration agreement were amended to give MorphoSys a one-time right to terminate the collaboration agreement, without notice, at either the end of 2016 or after review of clinical data from the first six patients enrolled and dosed in the Phase 1 trial. The requirement for further adjustments to the dosing regimen or other parts of the program could delay our development timeline or delay or prevent our ability to receive regulatory approval for APVO414. In December 2016, the agreement was modified to adjust the allocation of certain manufacturing and development costs and extend MorphoSys’ convenience termination rights. Under the amendment, the timeframe for a one-time right to terminate the collaboration agreement by MorphoSys has been extended from December 31, 2016 to June 30, 2017, or after review of clinical data from the first six patients enrolled and dosed in the APVO414 Phase I clinical trial. Effective August 31, 2017, MorphoSys terminated the MorphoSys collaboration agreement with Company in accordance with the terms of the Fourth Amendment which was effective December 7, 2015.ADAPTIR product candidates.

The procedures to obtain marketing approvals vary among countries and can involve additional clinical trials or other pre-filing requirements. The time required to obtain foreign regulatory approval may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all the risks associated with obtaining FDA approval, or different or additional risks. Regulatory agencies may have varying interpretations of the same data, and approval by one regulatory authority does not ensure approval by regulatory authorities in other jurisdictions. Accordingly, approval by the FDA does not ensure approval by the regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by the FDA or regulatory authorities in other foreign countries. Failure to obtain regulatory approval in one jurisdiction, however, may impact the decision of other jurisdictions. We may not be able to file for regulatory approvals and may not receive necessary approvals to commercialize our products and products in development in any market on a timely basis, if at all.

Biotechnology company stock prices have declined significantly in certain instances where companies have failed to obtain FDA or foreign regulatory authority approval of a product candidate or if the timing of FDA or foreign regulatory authority approval is delayed. If the FDA’s or any foreign regulatory authority’s response to any application for approval is delayed or not favorable for any of ourOur product candidates ~~our stock price could decline significantly.~~

~~Regulatory approval for any approved product is limited by the FDA to those specific indications~~are and conditions for which clinical safety and efficacy have been demonstrated, and we may incur significant liability if it is determined that we are promoting the “off-label” use of any of our products.

~~Any regulatory approval is limited to those specific diseases and indications for which a product is deemed~~will continue to be ~~safe~~subject to ongoing obligations and ~~effective by the FDA. For example, the FDA-approved label for IXINITY is not approved for use~~continued regulatory review, which may result in patients younger than twelve years old. In addition to the FDA approval required for new formulations, any new indication for an approved product also requires FDA approval. If we are not able to obtain FDA approval for any desired future indications for our products and product candidates, our ability to effectively market and sell our productssignificant additional expense. We may be ~~reduced and our business may be adversely affected.~~

~~While physicians may choose~~subject to prescribe drugs for uses that are not described in the product’s labeling and for uses that differ from those tested in clinical studies and approved by the regulatory authorities, our ability to promote the products is limited to those indications that are specifically approved by the FDA. These “off-label” uses are common across medical specialties and may constitute an appropriate treatment for some patients in varied circumstances. Regulatory authorities in the United States generally do not regulate the behavior of physicians in their choice of treatments. Regulatory authorities do, however, restrict communications by pharmaceutical companies on the subject of off-label use. If our promotional activitiespenalties if we fail to comply with ~~the FDA’s regulations~~regulatory requirements or ~~guidelines, we may be~~experience unanticipated problems with our products.

We and our product candidates are subject to ~~warnings from, or enforcement action~~extensive and ongoing requirements of and review by these authorities. In addition, our failure to follow FDA rules and guidelines relating to promotion and advertising may cause the FDA to issue warning letters or untitled letters, suspend or withdraw an approved product from the market, require a recall or institute fines, which could result in the disgorgement of money, operating restrictions, injunctions or civil or criminal enforcement, any of which could harm our business.

~~Notwithstanding the regulatory restrictions on off-label promotion,~~ the FDA and other regulatory authorities, ~~allow companies~~including requirements related to ~~engage in truthful, non-misleading~~the conduct of clinical and non-promotional scientific exchange concerning their products. We engage in medical education activities and communicate with investigators and potential investigators regarding our clinical trials. If the FDA or another regulatory or enforcement authority determines that our communications regarding our marketed products are not in compliance with the relevant regulatory requirements and that we have improperly promoted off-label uses, we may be subject to significant liability, including civil and administrative remedies as well as criminal sanctions.

~~Our products may face regulatory, legal or commercial challenges even after approval.~~

~~Any drug or, biologic for which we receive FDA approval, along with the~~non-clinical studies, manufacturing processes, post-approval clinical data, labeling, packaging, distribution, adverse event reporting, storage, recordkeeping, export, import, advertising, marketing, and promotional activities for such products. These requirements further include submissions of safety and other post-marketing information, including manufacturing deviations and reports, registration and listing requirements, the payment of annual fees, continued compliance with GMP-requirements relating to manufacturing, quality control, quality assurance, and corresponding maintenance of records and documents, and requirements regarding the distribution of samples to physicians.

If the FDA including, among other things, record keeping requirements, reporting of adverse experiences, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, current good manufacturing practices, or cGMP, and restrictions on advertising and promotion. Adverse events that are reported after marketing approval can result in additional limitations being placed on the product’s distribution or use and, potentially, withdrawal or suspension of the product from the market. In addition, various state laws require that companies that manufacture and/or distribute drug products within the state obtain and maintain a manufacturer or distributor license, as appropriate. Because of the breadth of these laws, it is possible that some of our business activities, or those of our third-party manufacturers and distributors, could be subject to challenge under one or more of such laws.

~~In addition, the FDA has post-approval authority to require post-approval clinical trials and/or safety labeling changes if warranted by the appearance~~comparable foreign regulatory authorities become aware of new safety ~~information. In certain circumstances,~~information after approval of any of our product candidates, they may, among other actions, withdraw approval, require labeling changes or establishment of a REMS or similar strategy, impose significant restrictions on a product’s indicated uses or marketing, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance.

We may not promote our products for conditions of use that are not included in the approved package inserts for our products. Certain additional restrictions on advertising and promotion exist for products that have so-called boxed warnings in their approved package inserts.

~~Failure by CMC~~manufacturers or ~~our other third-party manufacturers~~manufacturing processes, or failure to comply with regulatory requirements both before and after approval, may yield various results, including:

Any of these events could prevent us from achieving or maintaining product approval and market acceptance of the particular product candidate, if approved, or could substantially increase the costs and expenses of developing and commercializing such product, which in turn could delay or prevent us from generating significant revenues from its sale. Any of these events could further have other material and adverse effects on our operations and business and could adversely ~~affect their ability to supply products or ingredients to us. All facilities~~impact our stock price and manufacturing techniques used for the manufacture of pharmaceutical products must be operated in conformity with the FDA’s current cGMP requirements. The FDA enforces its cGMP and other requirements through periodic unannounced inspections of manufacturing facilities. If, in connection with any future inspection, the FDA finds that any of our third-party manufacturers is not in substantial compliance with cGMP requirements, or if the FDA is not satisfied with the corrective actions such manufacturer may take, the FDA may undertake certain enforcement actions, including product seizure or withdrawal of the product from the market, imposition of restrictions on the marketing or manufacturing of a product and suspension or withdrawal of regulatory approvals or refusal to approve pending applications or supplements.

Similar actions may be taken against us should we fail to comply with regulatory requirements, or later discover previously unknown problems with our products. Even if regulatory approval of a product is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. If we experience any of these post-approval events,could significantly harm our business, financial condition, results of operations, and prospects.

The FDA’s policies may change and additional government laws and regulations may be enacted that could prevent, limit, or delay regulatory approval of our product candidates, that could limit the marketability of our product candidates, or that could impose additional regulatory obligations on us. By example the change in the U.S. administration that occurred on January 20, 2021 may result in new or revised laws, regulatory requirements, and associated compliance obligations, as well as postponed or frozen regulatory requirements. Changes in medical practice and standard of care may also impact the marketability of our product candidates. If we are slow or unable to adapt to changes in existing requirements, standards of care, or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and be subject to regulatory enforcement action.

Should any of the above actions take place, they could adversely affect our ability to achieve or sustain profitability. Further, the cost of compliance with post-approval regulations may have a negative effect on our operating results ~~could be materially~~ and ~~adversely affected.~~financial condition.

If we fail to comply with foreign, federal, state, and ~~state~~local healthcare laws, including fraud and abuse and health information privacy and security laws, we could face substantial penalties and our business, results of operations, financial condition and prospects could be adversely affected.

As a biotechnology company, even though we do not provide healthcare services or receive payments directly from or bill directly to Medicare, Medicaid, or other third-party payors for our products, certain federal, state, local and ~~state~~foreign healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are ~~and will be~~ applicable to our business. We are subject to healthcare fraud and abuse and patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under the U.S. federal Anti-Kickback Statute, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Moreover, recent health care reform legislation has strengthened these laws. For example, the ~~Affordable Care Act,~~ACA, among other things, amends the intent requirement of the federal ~~anti-kickback~~Anti-Kickback Statute and criminal health care fraud statutes, so that a person or entity no longer needs to have actual knowledge of ~~this~~the statute or specific intent to violate it. In addition, the ~~Affordable Care Act~~ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the false claims statutes. Federal false claims laws prohibit any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government or knowingly making, or causing to be made, a false statement to get a false claim paid.False Claims Act.

Recently, several pharmaceutical and other healthcare companies have been prosecuted under the federal false claims laws for allegedly inflating drug prices they report to pricing services, which in turn are used by the government to set Medicare and Medicaid reimbursement rates, and for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. In addition, certain marketing practices, including off-label promotion, interactions with specialty pharmacies, and patient assistance programs may also violate ~~false claims~~fraud and abuse laws. To the extent that any product we make is sold in a foreign country, we may be subject to similar foreign laws and regulations.

Further, there has been a recent trend in the increase of federal and state laws and regulations regarding financial arrangements with physicians. The Affordable Care Act imposes new requirements to report certain financial arrangements with physicians and others, including reporting any “transfer of value” made or distributed to prescribers and other healthcare providers and reporting any ownership or investment interests held by physicians and their immediate family members during each calendar year, subject to federal implementation and enforcement policies.

In addition, certain ~~states~~state and local laws mandate that we comply with a state code of conduct, adopt a company code of conduct under state criteria, disclose marketing payments made to ~~physicians,~~health care professionals and entities, disclose drug pricing information and/or report compliance information to the state authorities. The shifting compliance environment and the need to build and maintain robust and expandable systems to comply in multiple jurisdictions with different compliance and reporting requirements increase the possibility that a pharmaceutical company may violate one or more of the requirements. Any failure to comply with these reporting requirements could result in significant fines and penalties.

The risks of complying with these laws cannot be entirely eliminated. The risk of violation of such laws is also increased because many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with applicable federal, state, local and ~~state~~foreign privacy, security, fraud and ~~fraud~~transparency laws may prove costly. If our past or present operations, or those of our distributors are found to be in violation of any of the laws described above or any other

governmental regulations that apply to us, we may be subject to ~~penalties,~~sanctions, including civil and administrative penalties, criminal ~~penalties,~~fines, damages, ~~fines,~~disgorgement, exclusion from participation in U.S. federal or state health care programs, individual imprisonment, integrity obligations, and the curtailment or restructuring of our operations, any of which could materially adversely affect our ability to operate our business and our financial results. Similarly, if healthcare providers, distributors or other entities with whom we do business are found to be out of compliance with applicable laws and regulations, they may be subject to sanctions, which could also have a negative impact on us.

If we fail to comply with our obligations under U.S. governmental pricing programs, we could be required to reimburse government programs for underpayments and could pay penalties, sanctions and fines.

On August 2, 2011, President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposalsOur employees, independent contractors, consultants, commercial partners, principal investigators, or CROs may engage in spending reductions. The Joint Select Committee on Deficit Reduction did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering mandatory reductions in federal spending by as much as $1.1 trillion from 2013 through 2021, referred to as sequestration. The Bipartisan Budget Act of 2013 and subsequent legislation provide billions in sequester relief, but also extends the 2% reduction in Medicare payments, discussed below through fiscal year 2025. Sequestration-related spending reductions may have a significant adverse impact on our business.

The issuance of regulations and coverage expansion by various governmental agencies relating to the Medicaid rebate program will continue to increase our costs and the complexity of compliance and will be time-consuming. Changes to the definition of “average manufacturer price,” or AMP, and the Medicaid rebate amount under the Affordable Care Act and Centers for Medicare & Medicaid Services’, or CMS’s, issuance of final regulations implementing those changes also has affected and could further affect our 340B “ceiling price” calculations. Because we participate in the Medicaid rebate program, we are required to report “average sales price,” or ASP, information to CMS for certain categories of drugs that are paid for under Part B of the Medicare program, including IXINITY. Future statutory or regulatory changes or CMS binding guidance could affect the ASP calculations for our products and the resulting Medicare payment rate, and could negatively impact our results of operations.

Pricing and rebate calculations vary among products and programs, involve complex calculations and are often subject to interpretation by us, governmental or regulatory agencies and the courts. The Medicaid rebate amount is computed each quarter based on our submission to CMS of our current AMP and “best price” for the quarter. If we become aware that our reporting for a prior quarter was incorrect, or has changed as a result of recalculation of the pricing data, we are obligated to resubmit the corrected data for a period not to exceed twelve quarters from the quarter in which the data originally were due. Any such revisions could have the impact of increasing or decreasing our rebate liability for prior quarters, depending on the direction of the revision. Such restatements and recalculations increase our costs for complying with the laws and regulations governing the Medicaid rebate program. Price recalculations also may affect the “ceiling price” at which we are required to offer our products to certain covered entities, such as safety-net providers, under the 340B/PHS drug pricing program.

In addition to retroactive rebate liability and the potential for 340B program refunds, if we are found to have made a misrepresentation in the reporting of ASP, we are subject to civil monetary penalties for each such price misrepresentation and for each day in which such price misrepresentation was applied. If we are found to have knowingly submitted false AMP or “best price” information to the government, we may be liable for civil monetary penalties per item of false information. Any refusal of a request for information or knowing provision of false information in connection with an AMP survey verification also would subject us to civil monetary penalties. In addition, our failure to submit monthly/quarterly AMP or “best price” information on a timely basis could result in a civil monetary penalty per day for each day the information is late beyond the due date. Such failure also could be grounds for CMS to terminate our Medicaid drug rebate agreement, pursuant to which we participate in the Medicaid program. In the event that CMS terminates our rebate agreement, no federal payments would be available under Medicaid or Medicare Part B for our covered outpatient drugs. Governmental agencies may also make changes in program interpretations, requirements or conditions of participation, some of which may have implications for amounts previously estimated or paid. We cannot assure you that our submissions will not be found by CMS to be incomplete or incorrect.

In order for our products to be reimbursed by the primary federal governmental programs, we report certain pricing data to the U.S. federal government. Compliance with reporting and other requirements of these federal programs is a pre-condition to: (i) the availability of federal funds to pay for our products under Medicaid and Medicare Part B; and (ii) procurement of our products by the Department of Veterans Affairs, or DVA, and by covered entities under the 340B/PHS program. The pricing data reported are used as the basis for establishing Federal Supply Schedule, or FSS, and 340B/PHS program contract pricing and payment and rebate rates under the Medicare Part B and Medicaid programs, respectively. Pharmaceutical companies have been prosecuted under federal and state false claims laws for submitting inaccurate and/or incomplete pricing information to the government that resulted in increased payments made by these programs. The rules governing the calculation of certain reported prices are highly complex. Although we maintain and follow strict procedures to ensure the maximum possible integrity for our federal pricing calculations, the process for making the required calculations involves some subjective judgments and the risk of errors always exists, which creates the potential for exposure under the false claims laws. If we become subject to investigationsmisconduct or other ~~inquiries concerning our compliance~~improper activities, including noncompliance with ~~price reporting laws~~regulatory standards and regulations, and our methodologies for calculating federal prices are found to include flaws or to have been incorrectly applied, we could be required to pay or be subject to additional reimbursements, penalties, sanctions or fines,requirements, which could have a material adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees, independent contractors, consultants, commercial partners, manufacturers, investigators, or CROs could include intentional, reckless, negligent, or unintentional failures to comply with FDA regulations or applicable fraud and abuse laws, provide accurate information to the FDA, properly calculate pricing information required by federal programs, comply with federal procurement rules or contract terms, report financial information or data accurately or disclose unauthorized activities to us. This misconduct could also involve the improper use or misrepresentation of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter this type of misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. Moreover, it is possible for a whistleblower to pursue a False Claims Act case against us even if the government considers the claim unmeritorious and declines to intervene, which could require us to incur costs defending against such a claim. Further, due to the risk that a judgment in a False Claims Act case could result in exclusion from federal health programs or debarment from government contracts, whistleblower cases often result in large settlements. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, financial condition, and results of ~~operations.~~

~~To be eligible to have our products paid for with federal funds under~~operations, including the Medicaid and Medicare Part B programs as well as to be purchased by certain federal agencies and certain federal grantees, we also must participate in the DVA FSS pricing program. To participate, we are required to enter into an FSS contract with the DVA, under which we must make our innovator “covered drugs” available to the “Big Four” federal agencies—the DVA, the U.S. Departmentimposition of Defense, or the DoD, the Public Health Service (including the Indian Health Service), and the Coast Guard—at pricing that is capped pursuant to a statutory federal ceiling price, or FCP, formula set forth in Section 603 of the Veterans Health Care Act of 1992, or VHCA. The FCP is based on a weighted average wholesale price known as the Non-Federal Average Manufacturer Price, or Non-FAMP, which manufacturers are required to report on a quarterly and annual basis to the DVA. Pursuant to the VHCA, knowing provision of false information in connection with a Non-FAMP filing can subject us to penalties of $100,000 for each item of false information. If we overcharge the government in connection with our FSS contract or Section 703 Agreement, whether due to a misstated FCP or otherwise, we are required to disclose the error and refund the difference to the government. The failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the False Claims Act and other laws and regulations. Unexpected refunds to the government, and responding to a government investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

~~The failure to obtain or maintain regulatory approval in international jurisdictions could prevent us from marketing our products abroad and could limit the growth of our business.~~

We currently sell and intend to continue to sell our products outside the United States. To market our products in the EU and many other foreign jurisdictions, we may need to obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. Approval by the FDA does not ensure approval by foreign regulatory authorities. The approval procedures in foreign jurisdictions can vary widely and can involve additional clinical trials and data review. We and our collaborative partners may not be able to obtain foreign regulatory approvals on a timely basis, if at all, and therefore we may be unable to commercialize our products internationally. The failure to obtain these approvals could harm our business.

~~Our international operations increase our risk of exposure to potential claims of bribery and corruption.~~

As we expand our commercialization activities outside of the United States, we are subject to an increased risk of inadvertently conducting activities in a manner that violates the FCPA, the U.K. Bribery Act of 2010, Canada’s Corruption of Foreign Public Officials Act,significant fines or other similar foreign laws, which prohibit corporations and individuals from paying, offering to pay, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. In the course of establishing and expanding our commercial operations and seeking regulatory approvals outside of the United States, we will need to establish and expand business relationships with various third parties and will interact more frequently with foreign officials, including regulatory authorities and physicians employed by state-run healthcare institutions who may be deemed to be foreign officials under the FCPA or similar foreign laws. If our business practices outside the United States are found to be in violation of the FCPA or similar foreign laws, we and our senior management may be subject to significant civil and criminal penalties, potential debarment from public procurement and reputational damage, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.sanctions.

Our operations, including our use of hazardous materials, chemicals, bacteria, and viruses, require us to comply with regulatory requirements and expose us to significant potential liabilities.

Our operations involve the use of hazardous materials, including chemicals, and may produce dangerous waste products. Accordingly, we, along with the third parties that conduct clinical trials and manufacture our products and product candidates on our behalf, are subject to federal, state, local and foreign laws and regulations that govern the use, manufacture, distribution, storage, handling, exposure, disposal and recordkeeping with respect to these materials. We are also subject to a variety of environmental and occupational health and safety laws. Compliance with current or future laws and regulations can require significant costs and we could be subject to substantial fines and penalties in the event of noncompliance. In addition, the risk of contamination or injury from these materials cannot be completely eliminated. In such event, we could be held liable for substantial civil damages or costs associated with the cleanup of hazardous materials.

~~Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.~~

EU Member States, Switzerland and other countries have adopted data protection laws and regulations, which impose significant compliance obligations. For example, the EU Data Protection Directive, as implemented into national laws by the EU Member States, imposes strict obligations and restrictions on the ability to collect, analyze and transfer personal data, including health data from clinical trials and adverse event reporting. Data protection authorities from the different EU Member States may interpret the EU Data Protection Directive and national laws differently, which adds to the complexity of processing personal data in the European Union, and guidance on implementation and compliance practices are often updated or otherwise revised. Our failure to comply with these laws could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results. The revised EU Data Protection Directive adopted in April 2016 may also increase our responsibility and liability in relation to personal data that we process, and we may be required to put in place additional mechanisms ensuring compliance with the new EU data protection rules.

~~Our business depends on our success in developing and commercializing our product candidates.~~

We have invested significant effort and financial resources in the development of our therapeutics and product candidates. In addition to our product sales, our ability to generate revenue is dependent on a number of factors, including the success of our development programs, the interest of commercial entities and non-governmental organizations and others in funding the development of our product candidates, the ability to attract and establish external development partnerships and the commercial viability of our developed product candidates. The commercial success of our product candidates will depend on many factors, including accomplishing the following in an economical manner:

If we are delayed or prevented from developing or commercializing a product candidate in a profitable manner, or if doing so requires us to incur significant unanticipated costs, our growth could be materially and adversely affected.

~~Clinical trials of product candidates are expensive and time-consuming, and their outcome is uncertain.~~

Before obtaining regulatory approval for the sale of our product candidates, we and our collaborative partners, where applicable, must conduct extensive preclinical studies and clinical trials to establish proof of concept and demonstrate the safety and efficacy of our product candidates. Preclinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of a clinical trial do not necessarily predict final results. An unexpected result in one or more of our clinical trials can occur at any stage of testing.

We may experience unforeseen events or issues during, or as a result of, preclinical testing or clinical trials. These issues and events, which could delay or prevent our ability to receive regulatory approval for a product candidate, include, among others:

For example, in December 2015, after a joint review of data from the Phase 1 dose escalation study of APVO414 in prostate cancer patients, the Company and MorphoSys concluded that the dosing regimen and administration required adjustment. Patients receiving weekly doses of APVO414 developed ADA. ADA developed in most patients including those receiving the maximum tolerated dose of drug which could be given safely on a weekly basis. These antibodies bind to the drug and reduce the concentration of active APVO414 in the blood and thus could potentially reduce its efficacy. However, we observed no safety issues related to the development of ADA. The cause of these antibodies is unclear but could be due to the weekly administration of the drug. We and MorphoSys amended the clinical protocol to provide continuous intravenous infusion as a way to administer higher levels of drug and prevent the development of ADA. There is no guarantee that this change in administration will enable higher dosing and/or prevent the development of ADA. Further adverse or inconclusive clinical results could require additional adjustments to the dosing regimen or other parts of the program and could delay or prevent our ability to receive regulatory approval for APVO414.

In addition, product candidates that experience success in preclinical testing and early-stage clinical trials will not necessarily experience the same success in late-stage clinical trials, which are required for marketing approval. The FDA and other countries’ regulatory authorities will allow us to begin clinical trials under an IND, or similar document in other countries only if we demonstrate in our submission that the potential product candidate will not expose humans to unreasonable risks and that the compound has pharmacological activity that justifies clinical development. It takes significant time and expense to generate the requisite data to support an IND or similar document. In many cases, companies spend the time and resources only to discover that the data are not sufficient to support an IND or similar document and therefore are unable to enter human clinical trials.

Even if we are successful in advancing a product candidate into the clinical development stage, before obtaining regulatory and marketing approvals, we must demonstrate through extensive human clinical trials that the product candidate is safe and effective for its intended use. Human clinical trials must be carried out under protocols that are acceptable to regulatory authorities and to the independent committees responsible for the ethical review of clinical studies. There may be delays in preparing protocols or receiving approval for them that may delay the start or completion of the clinical trials. This is applicable both domestically and internationally. Clinical practices vary globally, and there is a lack of harmonization among the guidance provided by various regulatory bodies of different regions and countries with respect to the data that is required to receive marketing approval, which makes designing global trials increasingly complex.

Serious adverse events, undesirable side effects or other unexpected properties of our product candidates may be identified that could delay, prevent or cause the withdrawal of regulatory approval, limit the commercial potential, or result in significant negative consequences following marketing approval.

Serious adverse events or undesirable side effects caused by, or other unexpected properties of any of our product candidates could cause us or regulatory authorities to interrupt, delay or halt our manufacturing and distribution operations and could result in a more restrictive label, the imposition of distribution or use restrictions or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities. If any of our product candidates are associated with serious adverse events or undesirable side effects or have properties that are unexpected, we may need to abandon their development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in clinical or earlier stage testing have later been found to cause undesirable or unexpected side effects that prevented further development of the compound.

For example, as noted above, APVO414 is currently being tested in its first clinical trial in humans. Twenty-one patients have received the drug. One of the significant serious adverse events associated with the drug is infusion reactions. Infusion reactions are often associated with the infusion of a protein and are expected with this drug that activates T-cells. The events that have been reported with infusion of the drug include: fever, fatigue, hypertension, bronchospasm, chills and rigors. The severity of these reactions varied by patient and were managed medically and resolved. In addition, in December 2015, we discovered that patients receiving weekly doses of our product candidate APVO414 developed ADA during use. This ADA, which was not associated with safety issues, developed in most patients including those receiving the maximum tolerated dose of drug which could be given safely on a weekly basis. Undesirable side effects, such as this, or other unexpected adverse events or properties of any of our candidates, could arise or become known either during clinical development or, if approved, after the approved product has been marketed. If such an event occurs during development, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our other product candidates. If such an event occurs, a number of potentially significant negative consequences may result, including:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate, or could substantially increase commercialization costs and expenses, which could delay or prevent us from generating revenue from the sale of our products and harm our business and results of operations.

We do not have the ability to independently conduct the clinical and non-clinical trials required to obtain regulatory approval for our product candidates. We depend on third parties, such as independent clinical investigators, contract research organizations and other third-party service providers to conduct the clinical and non-clinical trials of our product candidates and expect to continue to do so. We rely heavily on these third parties for successful execution of our clinical and non-clinical trials, but we do not exercise day-to-day control over their activities. Our reliance on these service providers does not relieve us of our regulatory responsibilities, including ensuring that our trials are conducted in accordance with the FDA-approved good clinical practices, or GCPs, and the plan and protocols contained in the relevant regulatory application. In addition, these organizations may not complete these activities on our anticipated or desired timeframe. We also may experience unexpected cost increases that are beyond our control. Problems with the timeliness or quality of the work of a contract research organization may lead us to seek to terminate the relationship and use an alternative service provider, which may prove difficult, costly and result in a delay of our trials. Any delay in or inability to complete our trials could delay or prevent the development, approval and commercialization of our product candidates.

If we, contract research organizations or other third parties assisting us or our study sites fail to comply with applicable GCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or its non-U.S. counterparts may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA or non-U.S. regulatory agencies will determine that any of our clinical trials comply with GCPs. In addition, our clinical trials must be conducted with product produced under GCPs and similar regulations outside of the United States. Our failure, or the failure of our product manufacturers, to comply with these regulations may require us to repeat or redesign clinical trials, which would increase our development costs and delay or impact the likelihood of regulatory approval.

If third parties do not carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical protocols, including dosing requirements, or regulatory requirements, or if they otherwise fail to comply with clinical trial protocols or meet expected deadlines, our clinical trials may not meet regulatory requirements. If our clinical trials do not meet regulatory requirements or if these third parties need to be replaced, our clinical trials may be extended, delayed, suspended or terminated. If any of these events occur, we may not be able to obtain regulatory approval of our product candidates or succeed in our efforts to create approved line extensions for certain of our existing products or generate additional useful clinical data in support of these products.

In certain cases, government entities conduct studies of our product candidates, and we may seek to rely on these studies in applying for marketing approval for certain of our product candidates. These government entities have no obligation or commitment to us to conduct or complete any of these studies or clinical trials and may choose to discontinue these development efforts at any time.

If we are unable to obtain any necessary third-party services on acceptable terms or if these service providers do not successfully carry out their contractual duties or meet expected deadlines, our efforts to obtain regulatory approvals for our product candidates may be delayed or prevented.

~~We may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable product candidates.~~

We continue to evaluate our business strategy and, as a result, may modify our strategy in the future. In this regard, we may, from time to time, focus our product development efforts on different product candidates or may delay or halt the development of various product candidates. This could require changes in our facilities and our personnel. Any product development changes that we implement may not be successful. In particular, we may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable product candidates.

Our decisions to allocate our research and development, management and financial resources toward particular product candidates or therapeutic areas may not lead to the development of viable commercial products and may divert resources from better opportunities. Similarly, our decisions to delay or terminate product development programs may also prove to be incorrect and could cause us to miss valuable opportunities.

If we are unable to protect our intellectual proprietary rights, our business could be harmed.

Our commercial success will depend, in large part, on our ability to obtain and maintain protection in the United States and other countries for the intellectual property covering or incorporated into our technology, products and product candidates. Obtaining and maintaining this protection is very costly. The patentability of technology in the biotechnology field generally is highly uncertain and involves complex legal and scientific questions. We cannot be certain that our patents and patent applications, including our own and those that we have rights through licenses from third parties, will adequately protect our intellectual property. Our success protecting our intellectual property depends significantly on our ability to:

We may not be able to obtain issued patents relating to our technology or ~~products.~~product candidates. Even if issued, patents may inadvertently lapse or be challenged, narrowed, invalidated, or circumvented, which could limit our ability to stop competitors from marketing similar products or limit the duration of patent protection we may have for our ~~products.~~product candidates. Further, patents may lapse prior to the regulatory approval of the underlying product in one or more territories. In the past, we have abandoned the prosecution and/or maintenance of patent applications related to patent families in the ordinary course of business. In the future, we may choose to abandon such prosecution and/or maintenance in a similar fashion. If these patent rights are later determined to be valuable or necessary to our business, our competitive position may be adversely affected. Changes in patent laws or administrative patent office rules or changes in interpretations of patent laws in the United States and in other countries may diminish the value of our intellectual property or narrow the scope of our patent protection, or result in costly defensive measures.

Our collaborative partners and licensors may not adequately protect our intellectual property rights. These third parties may have the first right to maintain or defend intellectual property rights in which we have an interest and, although we may have the right to assume the maintenance and defense of such intellectual property rights if these third parties do not do so, our ability to maintain and defend such intellectual property rights may be compromised by the acts or omissions of these third parties.

The cost of litigation to uphold the validity of patents, once obtained, to prevent infringement or to otherwise protect or enforce our proprietary rights could be substantial and, from time to time, our patents are subject to patent office proceedings. Some of our competitors may be better able to sustain the costs of complex patent litigation because they may have substantially greater financial resources. Intellectual property lawsuits are expensive and unpredictable and would consume management’s time and attention and other resources, even if the outcome were successful. In addition, there is a risk that a court would decide that our patents are not valid and that we do not have the right to stop the other party from using the inventions covered by or incorporating them. There is also a risk that, even if the validity of a patent were upheld, a court would refuse to stop the other party from using the invention(s), including on the grounds that its activities do not infringe the patent. If any of these events were to occur, our business, financial condition and operating results could be materially and adversely affected.

In addition to patent litigation, we may be a party to adversarial proceedings before the Patent Trial and Appeal Board (PTAB) of the US Patent and Trademark Office (USPTO), or the Opposition Division of the European Patent Office (EPO). Potential proceedings before the PTAB include inter partes review proceedings, post-grant review proceedings and interference proceedings. Depending on our level of success at the PTAB and Opposition Division of the EPO, these proceedings could adversely impact our intellectual property rights with respect to our products and technology.

In addition, the U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the value of patents, once obtained, and with regard to our ability to obtain patents in the future. Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

~~Our collaborative partners~~ Patent and ~~licensors may not adequately protect our~~ intellectual property ~~rights. These third parties~~laws outside of the United States may ~~have the first right to maintain or defend intellectual property rights in which we have an interest~~also change and although we may have the right to assume the maintenance and defense of such intellectual property rights if these third parties do not do so, our ability to maintain and defend such intellectual property rights may be ~~compromised by the acts or omissions of these third parties.~~uncertain.

Our patents, once obtained, also may not afford us protection against competitors with similar technology. Because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, or in some cases not at all, and because publications of discoveries in the scientific literature often lag behind actual discoveries, neither we nor our licensors can be certain that others have not filed or maintained patent applications for technology used by us or covered by our pending patent applications without our being aware of these applications.

We also will rely on current and future trademarks to establish and maintain recognized ~~brands.~~brands, including APTEVO THERAPEUTICS, APTEVO BIOTHERAPEUTICS, APTEVO RESEARCH AND DEVELOPMENT, the Aptevo logo, ADAPTIR, and ADAPTIR-FLEX in relevant jurisdictions. If we fail to acquire and protect such trademarks, our ability to market and sell our products, if approved for marketing, will be harmed. In addition, our current and ~~therefore~~future trademarks may be challenged, infringed, circumvented, declared generic, lapsed or determined to be infringing on or dilutive of other marks and we may not be able to protect our rights in these trademarks, which we need in order to build name recognition. Any of the foregoing could have a material and adverse effect on our business, financial condition and operating ~~results,~~results.

If approved, our products regulated as biologics may face competition from biosimilars approved through an abbreviated regulatory pathway.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity, and potency of the other company’s product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. We believe that any of our product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be ~~materially and adversely affected.~~shortened due to congressional action or otherwise, or that the FDA will not consider our investigational medicines to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation.

~~A European Patent Opposition~~There is a ~~European Patent Office proceeding that allows~~similar abbreviated pathway for ~~a 3rd party (opponent) to challenge~~ the ~~validity~~approval of biosimilar products in the EU. Reference products in the EU benefit from an eight year data exclusivity period during which the data included in the dossier for the reference product may not be referenced for the purposes of an ~~issued patent.

We were previously involved in five opposition proceedings in Europe relating to factor IX proteins. Baxter International Inc. (or Baxalta) was the sole counter-party in all proceedings. Two oppositions were decided in our favor and cannot be further appealed. Of the three remaining oppositions, Baxter either withdrew its patents or withdrew its opposition of a UNC patent (a licensed patent asset). Accordingly, we are no longer involved in adversarial proceedings with Baxter (or Baxalta) relating to these assets in Europe.

International patent protection is particularly uncertain, and if we are involved in additional opposition proceedings in foreign countries, we may have to expend substantial sums and management resources.

Patent and other intellectual property laws outside the United States are even more uncertain than in the United States and are continually undergoing review and revisions in many countries. Further, the laws of some foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. For example, certain countries do not grant patent claimsregulatory factors that are ~~directed~~still developing. If competitors are able to ~~business methods and processes. In addition, we may have to participate in additional opposition proceedings, like the proceedings described above, to determine the validity~~obtain marketing approval for biosimilars referencing any of our ~~foreign patents or~~products, if approved, our ~~competitors’ foreign patents,~~products may become subject to competition from such biosimilars, which ~~could result in substantial costs~~would impair our ability to successfully commercialize and ~~diversion~~generate revenues from sales of ~~our efforts.~~such products.

Our development and commercialization activities, as well as any product candidates or products resulting from these activities, may infringe or be claimed to infringe patents and other intellectual property rights of third parties under which we do not hold sufficient licenses or other rights. Third parties may be successful in obtaining patent protection for technologies that cover development and commercialization activities in which we are already engaged. These third parties may have substantially greater financial resources than us and could bring claims against us that could cause us to incur substantial expenses to defend against these claims and, if successful against us, could cause us to pay substantial damages. If a patent infringement or other similar suit were brought against us, we could be forced to stop or delay development, manufacturing or sales of the product or product candidate that is the subject of the suit. Intellectual property litigation in the biotechnology industry is common, and we expect this trend to continue.

As a result of patent infringement or other similar claims, or to avoid potential claims, we may choose or be required to seek a license from the third party and be required to pay license fees or royalties or both. These licenses may not be available on acceptable terms, or at all. Even if we were able to obtain a license, the rights may be non-exclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms, if at all, or if an injunction is granted against us, which could harm our business significantly.

There has been substantial litigation and other proceedings regarding patent and other intellectual property rights in the pharmaceutical and biotechnology industries. In addition to infringement claims against us, we may become a party to other patent litigation and other adversarial proceedings such as proceedings before the ~~PTAB~~Patent Trial Appeals Board and opposition proceedings in the European Patent Office, regarding intellectual property rights ~~with respect to~~that could impact our products and technology.

Patent litigation and other proceedings may also absorb significant management time. The cost to us of any patent litigation or other proceeding, even if resolved in our favor, could be substantial. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. Uncertainties resulting

from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace. Patent litigation and other proceedings may also absorb significant management time.

Our Aptevo trademarks may be opposed which could have a material and adverse effect on our business.

We have applications pending that cover the ~~APTEVO,~~ APTEVO THERAPEUTICS, APTEVO BIOTHERAPEUTICS, and APTEVO RESEARCH AND DEVELOPMENT trademarks. We refer to these trademarks as our house marks. If a third party opposes any of these house marks and we are unable to reach settlement prior to the commencement of an opposition proceeding, we may incur significant expense in the course of participating in the opposition process, which can be expensive and lengthy. Any settlement with a third party may result in our agreeing to be subject to restrictions on our use of the relevant house mark. In addition, if we are unsuccessful in an opposition against a house mark, we would lose the ability to obtain trademark registration for one or more uses of the relevant mark both in the United States and in other territories which could have a material and adverse effect on our business.

Synoptis Pharma Sp. z.o.o., or Synoptis, has opposed several of our house marks in the European Union. Despite efforts to initiate discussions with Synoptis regarding use of our house marks, Synoptis has refused to enter into settlement agreements. Our foreign counsel is investigating possible cancellation of Synoptis' registrations based on nonuse, which may allow the parties to enter negotiation discussions. If the event we are unsuccessful with our efforts to negotiate a settlement with Synoptis, we may lose our ability to obtain trademark registration for one or more of the house marks in the European Union, where Synoptis has opposed the marks, which could have a material and adverse effect on our business.

The Bristol Myers Squibb Company, or BMS, previously opposed several of our house marks in and outside the United States. We entered into a settlement and co-existence agreement with BMS and its licensee, Ono Pharmaceutical Co., Ltd on July 5, 2017. BMS subsequently withdrew oppositions of our house marks. The settlement and co-existence agreement places restrictions on how we can use our house marks and how we can seek trademark protection for our house marks.

Defending ourselves against such trademark infringement claims could be costly, time-consuming and distracting to management, and if we are unsuccessful in our defense, we could face an injunction and damages.

Defending ourselves against claims could be costly, time-consuming and distracting to management, and if we are unsuccessful in our defense, we could face an injunction prohibiting us from using the Aptevo trademarks and damages, all which could have a material and adverse effect on our business.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industry, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Failure to comply with our obligations in our intellectual property licenses with third parties, could result in loss of license rights or other damages.

We are a party to a number of license agreements and expect to enter into additional license agreements in the future. Our existing licenses impose, and we expect future licenses will impose, various diligence, milestone payment, royalty, insurance, and other obligations on us. If we fail to comply with these obligations, the licensor may have the right to terminate the license in whole or in part, terminate the exclusive nature of the license and/or sue us for breach, which could cause us to not be able to market any product that is covered by the licensed patents and may be subject to damages.

If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology and ~~products~~product candidates could be adversely affected.

In addition to patented technology, we rely upon unpatented proprietary technology, information processes and know-how. These types of trade secrets can be difficult to protect. We seek to protect this confidential information, in part, through agreements with our employees, consultants and third parties as well as confidentiality policies and audits, although these may not be successful in protecting our trade secrets and confidential information. These agreements may be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known, including through a potential cyber security breach, or may be independently developed by competitors. If we are unable to protect the confidentiality of our proprietary information and know-how, competitors may be able to use this information to develop products that compete with our products, which could adversely impact our business.

We may not be successful in establishing and maintaining collaborations that leverage our capabilities in pursuit of developing and commercializing our product candidates.

For each of our product candidates ~~including otlertuzumab,~~ we plan to evaluate the merits of entering into collaboration arrangements with third parties, including leading biotechnology companies or non-governmental organizations. In ~~addition, in~~ July 2017, we entered into a collaboration agreement with ~~Alligator Bioscience AB, or~~ Alligator pursuant to which Aptevo R&D and Alligator will collaboratively develop ALG.APV-527, a lead bispecific antibody candidate simultaneously targeting 4-1BB (CD137), a member of the TNFR superfamily of a costimulatory receptor found on activated ~~T cells,~~T-cells, and 5T4, a tumor antigen widely overexpressed in a number of different types of cancer. We ~~expect~~intend to ~~selectively~~ pursue collaboration arrangements with third parties that have particular technology, expertise or resources for the development or commercialization of our product candidates or for accessing particular markets. We face, and will continue to face, significant competition in seeking appropriate partners for our product candidates. If we are unable to identify partners whose capabilities complement and integrate well with ours and reach collaboration arrangements with such partners on a timely basis, on acceptable terms or at all, or if the arrangements we establish are unproductive for us, we may fail to meet our business objectives for the particular product candidate. Our ability to enter into such arrangements with respect to products in development that are subject to licenses may be limited by the terms of those licenses.

~~Any~~Our collaboration ~~that we have entered into, such as agreements~~agreement with ~~MorphoSys and~~ Alligator, or any collaboration agreement we may consider entering into, may not be successful and the success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborative partners. It is

likely that our collaborative partners will have significant discretion in determining the efforts and resources that they will apply to these collaborations.

The risks that we are subject to in any of our collaborations include, among others:

The failure of any of our current or future collaboration partners to perform as expected could place us at a competitive disadvantage and adversely affect us financially, including delay and increased costs of development, loss of market opportunities, lower than expected revenues and impairment of the value of the related product candidate. A loss of ~~Aptevo’s~~our collaboration agreement with Alligator would result in a burden of locating a replacement partner under potentially less favorable terms at an additional cost. Collaborations are a critical part of our business strategy, and any inability on our part to establish and successfully maintain such arrangements on terms favorable to us or to work successfully with our collaborative partners could have an adverse effect on our operations and financial performance.

~~Emergent may fail to perform under various transaction agreements that were executed as part of the separation or~~ongoing COVID-19 pandemic, we may ~~fail~~experience delays in opportunities to ~~have necessary systems~~develop our product candidates, due to financial and ~~services in place when certain of the transaction agreements expire.~~other impacts on potential partners.

In connection with our separation from Emergent, we and Emergent agreed to indemnify the ~~separation, we entered into a separation~~other party for certain liabilities. The Emergent indemnity may not be sufficient to hold us harmless from the full amount of liabilities for which Emergent will be allocated responsibility, and ~~distribution agreement and various other agreements with~~ Emergent including a transition services agreement, a tax matters agreement, an employee matters agreement, a manufacturing services agreement, a Canadian distributor agreement, a trademark license agreement and a product license agreement. Certain of these agreements provide for the performance of services by Emergent for a period of time after the separation. We will rely on Emergent to satisfy its performance obligations under these agreements. If Emergent is unable to satisfy its obligations under these agreements, including its indemnification obligations, we could incur operational difficulties or losses.

~~If we do not have in place our own systems and services, or if we do not have agreements with other providers of these services when the transition services or longer-term agreements terminate, we~~ may not be able to ~~operate~~satisfy its indemnification obligations in the future.

Pursuant to the separation agreement and certain other agreements with Emergent, Emergent has agreed to indemnify us for certain liabilities, and we agreed to indemnify Emergent for certain liabilities. Indemnities that we may be required to provide Emergent are not subject to any cap, may be significant and could negatively impact our business, ~~effectively~~particularly indemnities relating to our actions that could impact the tax-free nature of the distribution. Third parties could also seek to hold us responsible for any of the liabilities that Emergent has agreed to retain. Any amounts we are required to pay pursuant to these indemnification obligations and other liabilities could require us to divert cash that would otherwise have been used in furtherance of our operating business. Further, the indemnity from Emergent may not be sufficient to protect us against the full amount of such liabilities, and Emergent may not be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Emergent any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, results of operations and financial condition.

Our stock price has fluctuated in the past and is likely to be volatile in the future. Since August 1, 2016, the reported closing price of our common stock has fluctuated between $3.11 and $112 per share (as adjusted to reflect our 1-for-14 reverse stock split of our outstanding common stock that was effective on March 26, 2020). The stock market in general, and the market for biotechnology companies in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. In particular, the stock market has experienced extreme volatility in recent months as a result of the war in Ukraine and geopolitical climate. The market price of our common stock may ~~not~~fluctuate significantly due to a number of factors, some of which may be ~~successful in effectively~~beyond our control or ~~efficiently implementing these systems and services or in transitioning data from Emergent’s systems~~unrelated to ~~ours. These systems and services may also be more expensive or less efficient than the systems and services Emergent is expected to provide during the transition period.~~our operations, including, among others:

Biotechnology company stock prices have declined significantly in certain instances where companies have failed to obtain FDA or foreign regulatory authority approval of a product candidate or if the timing of FDA or foreign regulatory authority approval is delayed. If the FDA’s or any foreign regulatory authority’s response to any application for approval is delayed or not favorable for any of our product candidates, our stock price could decline significantly.

In addition, when the market price of a company’s common stock drops significantly, stockholders often institute securities class action lawsuits against the company. A lawsuit against us could cause us to incur substantial costs and could divert the time and attention of our management and other ~~management systems~~resources.

In the event that coverage under our directors’ and ~~resources~~officers’ liability insurance is reduced or terminated as a result of an ownership change or otherwise, our indemnification obligations and limitations of our directors’ and officers’ liability insurance may ~~not be adequately prepared to meet the ongoing financial reporting and other requirements of a standalone publicly-traded company.~~

Prior to our separation from Emergent, our financial results were included within the consolidated results of Emergent. We are now directly subject to substantial reporting and other obligations under the Securities Exchange Act of 1934, or Exchange Act. These reporting and other obligations place significant demand on our management, administrative and operational resources, including accounting resources. We may not have sufficient time to meet these obligations by the applicable deadlines.

Moreover, to comply with these requirements, we have migrated our systems, including information technology systems, implement additional financial and management controls, reporting systems and procedures. We expect to incur additional annual expenses related to these steps, and those expenses may be significant. If we are unable to upgrade our financial and management controls, reporting systems, information technology and procedures in a timely and effective fashion, our ability to comply with our financial reporting requirements and other rules that apply to reporting companies under the Exchange Act could be impaired. Any failure to achieve and maintain effective internal controls could have a material adverse effect on our ~~business,~~financial condition, results of operations and cash flows.

Under Delaware law, our certificate of incorporation, and our bylaws and certain indemnification agreements to which we are a party, we have an obligation to indemnify, or we have otherwise agreed to indemnify, certain of our current and former directors and officers with respect to past, current, and future investigations and litigation. In order to reduce the risk of expense of these obligations, we maintain directors’ and officers’ liability insurance. However, as a result of the Tang Ownership Change, the cost to us of our directors’ and officers’ liability insurance coverage has increased, and it may continue to increase in the future, or the coverage thereunder may be reduced or terminated in full. In the event that the coverage under our directors’ and officers’ liability insurance is reduced or terminated, we will be required to pay the expenses of indemnifying our current and former directors and officers in their defense of current and future investigations and litigation, which expenses may be significant. The increased costs to us of our directors’ and officers’ liability insurance coverage, or our indemnification obligations if our directors’ and officers’ liability insurance coverage is reduced or terminated, could result in the diversion of our financial resources, and may have a material adverse effect on our financial condition, results of operations and cash flows.

If we do not ~~continue to develop~~maintain effective internal controls, we may not be able to accurately report our financial results and our business could be harmed.

We and our independent registered public accounting firm identified a material weakness in our internal control over financial reporting as of and for the years ended December 31, 2015 and for quarters through September 30, 2016. A material weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Specifically, it was determined that a deferred tax liability should have been recorded associated with the difference between the book basis and the tax basis of the in-process research and development asset that was recorded as a part of an acquisition in 2010. As a result, we were required to restate our previously issued audited financial statements for the year ended December 31, 2015 and unaudited financial information for the quarter ended March 31, 2016, included in the Company’s Registration Statement on Form 10, and unaudited financial information for the quarters ended June 30, 2016 and September 30, 2016 included in the Company’s Quarterly Report on Form 10-Q for the quarters ended June 30, 2016 and September 30, 2016.

The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, ~~beginning in 2018,~~ Section 404 of the Sarbanes-Oxley Act, or Section 404, ~~will require~~requires us to perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on, and our independent registered public accounting firm potentially to attest to, the effectiveness of our internal control over financial reporting. AsIn the past, we were an emerging growth company ~~we have~~and availed ourselves of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404. However, we ~~may~~will no longer avail ourselves of this exemption ~~when~~since we ~~cease~~ceased to be an emerging growth ~~company.~~company since August 2021. When our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our compliance with applicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Investor perceptions of our company may suffer if material weaknesses are found, and this could cause a decline in the market price of our common stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could harm our operating results and reputation. If we are unable to implement these requirements effectively or efficiently, it could

harm our operations, financial reporting, or financial results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm.

In connection with our separation from Emergent, we and Emergent agreed to indemnify the other party for certain liabilities. The Emergent indemnity may not be sufficient to hold us harmless from the full amount of liabilities for which Emergent will be allocated responsibility, and Emergent may not be able to satisfy its indemnification obligations in the future.

Pursuant to the separation agreement and certain other agreements with Emergent, Emergent has agreed to indemnify us for certain liabilities, and we agreed to indemnify Emergent for certain liabilities. Indemnities that we may be required to provide Emergent are not subject to any cap, may be significant and could negatively impact our business, particularly indemnities relating to our actions that could impact the tax-free nature of the distribution. Third parties could also seek to hold us responsible for any of the liabilities that Emergent has agreed to retain. Any amounts we are required to pay pursuant to these indemnification obligations and other liabilities could require us to divert cash that would otherwise have been used in furtherance of our operating business. Further, the indemnity from Emergent may not be sufficient to protect us against the full amount of such liabilities, and Emergent may not be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Emergent any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, results of operations and financial condition.

If the distribution, together with certain related transactions, does not qualify as a tax-free transaction described under Sections 355 and 368(a)(1)(D) of the Code, our stockholders could be subject to significant tax liabilities, and, in certain circumstances, we could be required to indemnify Emergent for taxes and related expenses resulting from the failure of the transaction to so qualify.

It is intended that the distribution, together with certain related transactions, will generally be tax-free to Emergent and its stockholders for U.S. federal income tax purposes. Emergent has received a favorable private letter ruling from the IRS regarding certain U.S. federal income tax matters relating to the distribution and certain related transactions. It was a condition to the distribution that (i) the private letter ruling from the IRS continue to be valid and in full force and effect and (ii) Emergent receive an opinion from WilmerHale LLP, in a form and substance satisfactory to Emergent, substantially to the effect that, for U.S. federal income tax purposes, the distribution and certain related transactions, taken together, will qualify as a transaction described under Sections 355(a) and 368(a)(1)(D) of the Internal Revenue Code, or the Code. The IRS private letter ruling is based upon certain facts and representations submitted by Emergent to the IRS. In addition, the opinion from WilmerHale LLP was based upon and rely on, among other things, the IRS private letter ruling and certain facts and assumptions, as well as certain representations and covenants of Emergent and Aptevo contained in the tax matters agreement and certain representations contained in representation letters provided by Emergent, Aptevo and certain stockholders to WilmerHale LLP, including representations and covenants relating to the past and future conduct of Emergent, Aptevo and such stockholders. If any of these facts, assumptions, representations, or covenants is, or becomes, inaccurate or incomplete, the IRS private letter ruling and/or the opinion of WilmerHale LLP may be invalid and the conclusions reached therein could be jeopardized. In addition, the IRS private letter ruling only addresses certain limited matters relevant to determining whether the distribution, together with certain related transactions, qualifies as a transaction described under Sections 355 and 368(a)(1)(D) of the Code, and the opinion of WilmerHale LLP represents the judgment of such counsel which is not binding on the IRS or any court. Accordingly, notwithstanding the IRS private letter ruling and the opinion of WilmerHale LLP, there can be no assurance that the IRS will not assert that the distribution and/or certain related transactions should be treated as a taxable transaction for U.S. federal income tax purposes or that a court would not sustain such a challenge.

If the distribution, together with certain related transactions, does not qualify as a tax-free transaction described under Sections 355 and 368(a)(1)(D) of the Code, for U.S. federal income tax purposes, in general, (i) Emergent would recognize taxable gain on the distribution equal to the amount by which the fair market value of the Aptevo common stock distributed to Emergent stockholders exceeds Emergent’s tax basis in its shares of our common stock and (ii) each Emergent stockholder would be treated as receiving a taxable distribution in an amount equal to the fair market value of the Aptevo common stock received by such stockholder.

Under the tax matters agreement that we entered into with Emergent, we may be required to indemnify Emergent against any tax liabilities and related expenses resulting from the failure of the distribution, together with certain related transactions, to qualify as a transaction described under Sections 355 and 368(a)(1)(D) of the Code to the extent that the failure to so qualify is attributable to actions, events or transactions relating to our stock, assets or business, or a breach of the relevant representations or covenants made by us in the tax matters agreement or the IRS private letter ruling or in the representation letters provided to WilmerHale LLP.

~~Certain of our executive officers and/or directors may have actual or potential conflicts of interest because of their previous positions at Emergent.~~

The ownership by our executive officers and/or directors of shares of Emergent common stock, stock options or other equity awards may create, or may create the appearance of, conflicts of interest. Because of their current or former positions with Emergent, certain of our executive officers and/or directors own shares of Emergent common stock, stock options to purchase Emergent common stock or other equity awards. Shares of Emergent common stock, stock options to purchase Emergent common stock or other equity awards may comprise a significant portion of some of these individuals’ total personal financial assets. Even though our executive officers and/or directors who were previously employees of Emergent have ceased to be employees of Emergent, some of our executive officers and/or directors continue to have a financial interest in Emergent common stock, which may create, or may create the appearance of, conflicts of interest when these individuals are faced with decisions that could have different implications for Emergent than the decisions have for us.

~~We cannot be certain that an active trading market for our common stock will be sustained and our stock price may fluctuate significantly.~~

~~An active trading market for our common stock may not sustained, nor can we predict the prices at which shares of our common stock may trade in the future.~~

Our stock price has fluctuated in the past and is likely to be volatile in the future. Since August 1, 2016, the reported sale price of our common stock has fluctuated between $1.19 and $3.33 per share. The stock market in general, and the market for biotechnology companies in particular, have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price of our common stock may fluctuate significantly due to a number of factors, some of which may be beyond our control or unrelated to our operations, including, among others:

The restatement of our previously issued financial statements, the misstatements that resulted in such restatement, and the material weakness that has been identified in our internal control over financial reporting, could expose us to additional risks that could have a material adverse effect on our business, financial condition, cash flows and results of operations and could cause the market value of our common stock to decline.

As discussed in our Annual Report on Form 10-K for the year ended December 31, 2016, and in Note 10 – Restatement, to the financial statements included in this Quarterly Report on Form 10-Q we restated our previously issued audited consolidated financial statements for the year ended December 31, 2015 and the unaudited financial information related to March 31, 2016 and June 30, 2016 and the three and nine months ended September 30, 2016. This restatement, along with the material weakness that were identified in our internal control over financial reporting, could expose us to potential claims and additional risks that could have a material adverse effect on our business, financial condition, cash flows and results of operations and could cause the market value of our common stock to decline. We have implemented actions with respect to our internal controls but to the extent these steps are not successful, we could be forced to incur additional time and expense or we may not be able to produce accurate and timely financial results. As a result of the restatement and the material weakness in our internal controls, we could be subject to stockholder, governmental, or other actions in connection with the restatement or related or other matters. Any such proceedings would, regardless of the outcome, consume a significant amount of management’s time and attention and would result in additional legal, accounting and other costs. If we were not to prevail in any such proceedings, we could be required to pay substantial damages or settlement costs. In addition, the restatement and related matters could impair our reputation or could lead to a loss of investor confidence.

The public announcement of data from clinical ~~studies~~trials or news of any developments related to our product pipeline may cause significant volatility in our stock price.

The announcement of data from clinical ~~studies~~trials by us or our collaborative partners or news of any developments related to our key pipeline product candidates may cause significant volatility in our stock price. Furthermore, the announcement of any negative or unexpected data or the discontinuation of development of any of our key pipeline product candidates, or any delay in our anticipated timelines for filing for regulatory approval, could cause our stock price to decline significantly. There can be no assurance that data from clinical ~~studies~~trials will support a filing for regulatory approval or even if approved, that any of our key pipeline products will become commercially successful.

Our common stock may be at risk for delisting from the Nasdaq Capital Market in the future if we do not maintain compliance with NASDAQ’s continued listing requirements. Delisting could adversely affect the liquidity of our common stock and the market price of our common stock could decrease.

Our common stock is currently listed on the Nasdaq Capital Market LLC (“Nasdaq”). The Nasdaq Stock Market LLC has minimum requirements that a company must meet in order to remain listed on Nasdaq, including corporate governance standards and a requirement that we maintain a minimum closing bid price of $1.00 per share.

On April 1, 2022, the Company received a letter from Nasdaq indicating that it is not in compliance with Nasdaq Listing Rule 5550(b)(1), which requires companies listed on The Nasdaq Capital Market to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing. On its annual report for the year ended December 31, 2021, the Company reported stockholders’ equity of $1,216,000, and, as a result, does not currently satisfy Listing Rule 5550(b)(1).

Nasdaq’s letter has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on Nasdaq, subject to the Company’s compliance with the other continued listing requirements. Nasdaq’s letter provides the Company 45 calendar days, or until May 16, 2022, to submit a plan to regain compliance. If the plan is accepted, the Company can be granted up to 180 calendar days from April 1, 2022, to evidence compliance. There can be no assurance that the Company will be able to regain compliance with all applicable continued listing requirements or that its plan will be accepted by the Nasdaq staff. In the event the plan is not accepted by the Nasdaq staff, or in the event the plan is granted but the Company fails to regain compliance within the plan period, the Company would have the right to a hearing before an independent panel. The hearing request would stay any suspension or delisting action pending the conclusion of the hearing process and the expiration of any additional extension period granted by the panel following the hearing.

If we fail to maintain such minimum requirements and a final determination is made by Nasdaq that our common stock must be delisted, the liquidity of our common stock would be adversely affected and the market price of our common stock could decrease. In addition, if delisted, we would no longer be subject to Nasdaq rules, including rules requiring us to have a certain number of independent directors and to meet other corporate governance standards. Our failure to be listed on Nasdaq or another established securities market would have a material adverse effect on the value of your investment in us.

If our common stock is not listed on Nasdaq or another national exchange, the trading price of our common stock is below $5.00 per share and we have net tangible assets of $6,000,000 or less, the open-market trading of our common stock will be subject to the “penny stock” rules promulgated under the Securities Exchange Act of 1934, as amended. If our shares become subject to the “penny stock” rules, broker-dealers may find it difficult to effectuate customer transactions and trading activity in our securities may be adversely affected. Under these rules, broker-dealers who recommend such securities to persons other than institutional accredited investors must:

As a result of these requirements, the market price of our securities may be adversely impacted, and current stockholders may find it more difficult to sell our securities.

In the future, your percentage ownership in Aptevo may be diluted because of equity issuances for acquisitions, capital market transactions or otherwise, including, but not limited to, equity issuances under our existing Purchase Agreement with Lincoln Park Financial LLC, under our Equity Distribution Agreement with Piper Sandler, under our Rights Plan with Broadridge Corporate Issuer Solutions, Inc., upon the exercise of warrants issued in connection with our March 2019 public offering, and equity awards to our directors, officers and employees. Our employees have options to purchase shares of our common stock and ~~we have issued significant number of restricted stock units that will vest over time. From~~from time to time, we ~~may~~expect to issue additional options, restricted stock units, or other stock-based awards to our employees under our employee benefits plans.

In addition, our restated certificate of incorporation authorizes us to issue, without the approval of our stockholders, one or more classes or series of preferred stock having such designation, powers, preferences and relative, participating, optional and other special rights, including preferences over our common stock respecting dividends and distributions, as our board of directors generally may determine. The terms of one or more classes or series of preferred stock could dilute the voting power or reduce the value of our common stock. For example, we could grant the holders of preferred stock the right to elect some number of our directors in all events or on the happening of specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we could assign to holders of preferred stock could affect the residual value of the common stock.

Fuad El-Hibri, the chairman of our Board of Directors, has significant influence over us through his substantial beneficial ownership of our common stock, including an ability to influence the election of the members of our Board of Directors, or delay or prevent a change of control of us.

Mr. El-Hibri has the ability to significantly influence the election of the members of our Board of Directors due to his substantial beneficial ownership of our common stock. As of September 30, 2017, Mr. El-Hibri was the beneficial owner of approximately 15% of our outstanding common stock. As a result, Mr. El-Hibri could delay or prevent a change of control of us that may be favored by other directors or stockholders and otherwise exercise substantial control over all corporate actions requiring board or stockholder approval, including any amendment of our certificate of incorporation or by-laws. The control by Mr. El-Hibri may prevent other stockholders from influencing significant corporate decisions. In addition, Mr. El-Hibri’s significant beneficial ownership of our shares could present the potential for a conflict of interest.

Provisions under Delaware law and in our restated certificate of incorporation, ~~and~~ amended and restated by-laws and rights agreement may discourage acquisition proposals, delay a change in control or prevent transactions that stockholders may consider favorable.

Certain provisions in our restated certificate of incorporation and amended and restated by-laws, and under Delaware law, may discourage, delay, or prevent a merger, acquisition or other changes in control that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our incumbent directors and management.

The affirmative vote of holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required to amend or repeal the above provisions of our certificate of incorporation. The affirmative vote of either a majority of the directors present at a meeting of our Board of Directors or holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required to amend or repeal our by-laws.

In addition, Section 203 of the General Corporation Law of Delaware prohibits a corporation from engaging in a business combination with an interested stockholder, generally a person which, together with its affiliates, owns or within the last three years has owned 15% or more of the corporation’s voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, Section 203 may discourage, delay or prevent a change in control of us. Tang is an interested stockholder for purposes of Section 203.

~~In addition, under~~Moreover, we currently have a short-term stockholder rights agreement in effect. This rights agreement was amended on November 4, 2021 to extend the ~~tax matters~~expiration date of such agreement ~~for~~from November 8, 2021 to November 5, 2022. This rights agreement could render more difficult, or discourage a ~~period~~merger, tender offer, or assumption of two years following the separation, we are restricted from taking certain actions (including restrictions on business combinations and share issuances) that could cause the distribution, together with certain related transactions, to fail to qualify as a tax-free transaction for U.S. federal income tax purposes. We would be required to indemnify Emergent for any taxes and related expenses resulting from the failurecontrol of the ~~transactions~~Company that is not approved by our Board that some stockholders may consider favorable. The rights agreement, however, should not interfere with any merger, tender or exchange offer or other business combination approved by our Board. Nor does the rights agreement prevent our Board from considering any offer that it considers to ~~so qualify~~be in the best interest of our stockholders.

Our bylaws include a forum selection clause, which may impact your ability to bring actions against us.

Subject to certain limitations, our bylaws provide that, unless we consent in writing to the ~~extent that~~selection of an alternative forum, the ~~failure is attributable to actions, events or transactions relating our stock, assets or business, and this indemnity obligation might discourage, delay or prevent a change~~Court of ~~control that you may consider favorable.~~

Our by-laws include an exclusive forum provision that could limit our stockholders’ ability to obtain a judicial forum viewed by stockholders as more favorable for disputes with us or our directors, officers or other employees or certain stockholders.

~~Our by-laws provide that the~~ Chancery ~~Court of~~in the State of Delaware will be the sole and exclusive forum for ~~certain legal proceedings,~~any stockholder (including a beneficial owner) to

bring: (a) any derivative action or proceeding brought on our behalf; (b) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees or our stockholders; (c) any action asserting a claim arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws; or (d) any action asserting a claim governed by the internal affairs doctrine. In addition, our bylaws provide that unless we consent in writing to the selection of an alternative ~~forum. This~~forum, the federal district courts of the United States will be the exclusive forum ~~provision~~for resolving any complaint asserting a cause of action arising under the federal securities laws of the United States against us, our officers, directors, employees or underwriters. These limitations on the forum in which stockholders may ~~limit~~initiate action against us could create costs, inconvenience or otherwise adversely affect your ability to seek legal redress.

Section 22 of the ~~ability of~~Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, a court may decline to enforce these exclusive forum provisions with respect to suits brought to enforce any duty or liability created by the Securities Act or any other claim for which the federal and state courts have concurrent jurisdiction, and our stockholders may not be deemed to ~~bring a claim in a judicial forum that such stockholders find favorable for disputes~~have waived our compliance with ~~us or our directors or officers, which may discourage lawsuits against us or our directors or officers. Alternatively, if~~the federal securities laws and the rules and regulations thereunder. If a court ~~outside of Delaware~~ were to find ~~this~~the exclusive forum ~~provision~~provisions to be inapplicable ~~to,~~ or unenforceable in ~~respect of, one or more of the types of actions or proceedings described above,~~an action, we may incur additional costs associated with resolving such ~~matters~~action in other ~~jurisdictions,~~jurisdictions.

We may be subject to periodic litigation, which could ~~adversely affect~~result in losses or unexpected expenditure of time and resources.

From time to time, we may be called upon to defend ourselves against lawsuits relating to our business. Any litigation, regardless of its merits, could result in substantial costs and a diversion of management’s attention and resources that are needed to successfully run our business. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of any such proceedings. An unfavorable outcome in any such proceedings could have an adverse impact on our business, financial condition orand results of operations. If our stock price is volatile, we may become involved in securities class action lawsuits in the future.

Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.

EU Member States, Switzerland and other countries have adopted data protection laws and regulations, which impose significant compliance obligations. For example, European Union, or EU, member states and other foreign jurisdictions, including Switzerland, have adopted data protection laws and regulations which impose significant compliance obligations. Moreover, the collection and use of personal health data in the EU is now governed under the EU General Data Protection Regulation, or the GDPR, effective in May 2018. The GDPR, which is wide-ranging in scope, imposed several requirements relating to the consent of the individuals to whom the personal data relates, the information provided to the individuals, the security and confidentiality of the personal data, data breach notification and the use of third-party processors in connection with the processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the EU to the U.S., provides an enforcement authority and imposes large penalties for noncompliance, including the potential for fines of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. The GDPR requirements apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, including employee information. The GDPR increases our responsibility and liability in relation to personal data that we process, including in clinical trials, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, which could divert management’s attention and increase our cost of doing business. In addition, new regulation or legislative actions regarding data privacy and security (together with applicable industry standards) may increase our costs of doing business. However, despite our ongoing efforts, we may not be successful either due to various factors within our control, such as limited financial or human resources, or other factors outside our control. It is also possible that local data protection authorities may have different interpretations of the GDPR, leading to potential inconsistencies amongst various EU member states. Any failure or alleged failure (including as a result of deficiencies in our policies, procedures, or measures relating to privacy, data security, marketing, or communications) by us to comply with laws, regulations, policies, legal or contractual obligations, industry standards, or regulatory guidance relating to privacy or data security, may result in governmental investigations and enforcement actions, litigation, fines and penalties or adverse publicity. In addition, we expect that there will continue to be new proposed laws, regulations and industry standards relating to privacy and data protection in the United States, the EU and other jurisdictions, such as the California Consumer Privacy Act of 2018, which has been characterized as the first “GDPR-like” privacy statute to be enacted in the United States, and we cannot determine the impact such future laws, regulations and standards may have on our business.

If we experience a significant disruption in our information technology systems or breaches of data security, including due to a cyber-security incident, our business could be adversely affected.

We rely on information technology systems to keep financial records, capture laboratory data, maintain clinical trial data and corporate records, communicate with staff and external parties and operate other critical functions. Our information technology systems are potentially vulnerable to disruption due to breakdown, malicious intrusion and computer viruses or other disruptive events including but not limited to natural disaster. The impact of the ongoing COVID-19 pandemic also poses an increased security risk, due to the remote working environment.

~~Because~~We also face the challenge of promptly detecting and remediating any cyber-security breaches. Our information technology systems security measures are focused on the prevention, detection and remediation of damage from computer viruses, unauthorized access, cyber-attack and other similar disruptions. However, our information technology systems protection measures may not be successful in preventing unauthorized access, intrusion and damage. Threats to our systems can derive from human error, fraud or malice on the part of employees or third parties, including computer hackers, encryption by ransomware, or may result from technological failure.

If we ~~currently do not expect~~were to ~~pay dividends, investors will benefit from an investment~~experience a prolonged system disruption in our ~~common stock only~~information technology systems or those of certain of our vendors, it could delay or negatively impact our development and commercialization of our product candidates, which could adversely impact our business. If operations at our facilities were disrupted, it may cause a material disruption in our business if ~~it appreciates~~we are not capable of restoring function on an acceptable timeframe.

In addition, as discussed above, our information technology systems are potentially vulnerable to data security breaches—whether by employees or others, intentionally or unintentionally—which may expose sensitive or personal data to unauthorized persons. Such data security breaches could lead to the loss of trade secrets or other intellectual property, or could lead to the public exposure of personal information (including sensitive personal information) of our employees, customers and others, any of which could have a material adverse effect on our business, financial condition and results of operations.

Moreover, a security breach or privacy violation that leads to destruction, loss, alteration, unauthorized use or access, disclosure or modification of, personally identifiable information or personal data, could harm our reputation, compel us to comply with federal, state and/or international breach notification laws, subject us to mandatory corrective or regulatory action, require us to verify the correctness of database contents and otherwise subject us to liability under laws and regulations that protect personal data, including the GDPR and the California Consumer Privacy Act of 2018, which could disrupt our business, result in ~~value.~~increased costs or loss, and/or result in significant legal and financial exposure. In addition, a data security breach could result in loss of clinical trial data or damage to the integrity of that data.

~~We anticipate that~~If we ~~will retain all our future earnings, if any,~~are unable to ~~support~~implement and maintain adequate organizational and technical measures to prevent such security breaches or privacy violations, or to respond adequately in the event of a breach, our operations could be disrupted, and ~~our proprietary drug development programs~~we may suffer loss of reputation, problems with regulatory authorities, financial loss and ~~product candidates and pursue~~ other ~~opportunities.~~negative consequences. In addition, these breaches and other inappropriate access can be difficult to detect, and any delay in identifying them may lead to increased harm of the type described above.

If a breach of our ~~credit facility limits~~information technology systems occurs, we may incur additional costs related to repairing or rebuilding our ~~ability~~internal systems, complying with breach notification laws, defending legal claims or proceedings, responding to ~~pay dividends. As~~regulatory actions, incurring penalties, and paying damages. Moreover, it may be determined that as a result ~~we currently do not expect to pay dividends for the foreseeable future.

We cannot guarantee that we will pay any dividends in the future or continue to pay any dividend if we were to commence paying dividends. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for our stockholders for the foreseeable future.reputation.

A significant portion of our shares may be sold into the market at any time which could depress our stock ~~price~~price.

If our stockholders sell a substantial number of shares of our common stock in the public market, our market price could decline. In connection with the transaction with Lincoln Park, we have agreed to register under the Securities Act of 1933, as amended, the resale of shares of common stock that have been and may be issued under the Purchase Agreement with Lincoln Park. Any such sales by Lincoln Park, or the perception that such sales may occur, could decrease the market price of our common stock. In addition, holders of an aggregate of approximately three million shares of our common stock have the right to require us to register these shares of common stock under ~~the Securities Act of 1933, as amended, under~~ specified circumstances.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
