~~FORWARD-LOOKING STATEMENTS~~

~~This Quarterly Report on Form~~

~~10-Q~~

~~contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, contained in this Quarterly Report on Form~~

~~10-Q,~~

including statements regarding our strategy, future operations, future financial position, projected costs, prospects, plans and objectives of management, are forward-looking statements. In some cases, you can identify forward-looking statements by terms including, but not limited to, “may,” “likely,” “will,” “should,” “would,” “design,” “expect,” “seek,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions.

~~These forward-looking statements include, but are not limited to, statements about:~~

~~our ongoing and planned preclinical studies and clinical trials;~~

~~preclinical study data and clinical trial data and the timing of results of our ongoing clinical studies and/or trials;~~

~~our plans to seek and enter into clinical trial collaborations and other broader collaborations;~~

~~the direct and indirect impact of the~~

~~COVID-19~~

~~pandemic on our business operations and financial condition, including manufacturing, research and development costs, clinical trials, regulatory processes and employee expenses; and~~

~~our estimates regarding prospects, strategies, expenses, operating capital requirements, results of operations and needs for additional financing.~~

Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. Factors that could cause actual results or events to differ materially from the forward-looking statements that we make include, but are not limited to, the following:

We are very early in our development efforts and our product candidates may not be successful in later stage clinical trials. Results obtained in our preclinical studies and clinical trials to date are not necessarily indicative of results to be obtained in future clinical trials. As a result, our product candidates may never be approved as marketable therapeutics.

We will need additional funding to complete the development of our product candidates and before we can expect to become profitable from the sales of our products, if approved. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs or commercialization efforts.

We rely, and expect to continue to rely, on third parties to conduct our clinical trials and to manufacture our product candidates for preclinical and clinical testing. These third parties may not perform satisfactorily, which could delay our product development activities.

If we are unable to adequately protect our proprietary technology or obtain and maintain issued patents which are sufficient to protect our product candidates, others could compete against us more directly, which would have a material adverse impact on our business, results of operations, financial condition and prospects.

We may not be able to retain key executives or to attract, retain and motivate key personnel. If we are unable to retain such key personnel, it could have a material adverse impact on our business and prospects.

~~Business interruptions resulting from the coronavirus disease~~

~~(“COVID-19”)~~

~~outbreak or similar public health crises could cause a disruption of the development of our product candidates and adversely impact our business.~~

~~You should read this Quarterly Report on Form~~

~~10-Q~~

~~and the documents that we have filed as exhibits to this Quarterly Report on Form~~

~~10-Q~~

completely and with the understanding that our actual future results may be materially different from what we expect. You should also read carefully the factors described in “Item 1A. Risk Factors” in our ~~Annual Report on Form~~

~~10-K~~ for the year ended December 31, 2020, as filed with the Securities and Exchange Commission (the “SEC”) on March 30, 2021, to better understand the risks and uncertainties inherent in our business and underlying any forward-looking statements. You are advised, however, to consult any further disclosures we make on related subjects in our subsequent Quarterly Reports on

~~Form 10-Q,~~

~~Current Reports on Form~~

~~8-K,~~

~~press releases, and our website. Any forward-looking statements that we make in this Quarterly Report on~~

~~Form 10-Q~~

~~speak only as of the date of this Quarterly Report on Form~~

~~10-Q,~~

~~and we undertake no obligation to update such statements to reflect events or circumstances after the date of this Quarterly Report on~~

~~Form 10-Q~~

~~or to reflect the occurrence of unanticipated events.~~

Notes to Condensed Consolidated Financial Statements

1. Nature of Business and Summary of Significant Accounting Policies

Nature of Business

F-star

Therapeutics, Inc.

(collectively with its subsidiaries,

~~“F-star”~~

“F-star” or the “Company”) is a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer.

F-star is pioneering the use of tetravalent (2+2) bispecific antibodies to create a paradigm shift in cancer therapy. The Company has four second-generation immuno-oncology ("IO") therapeutics in the clinic, each directed against some of the most promising IO targets in drug development, including LAG-3 and CD137. F-star’s

proprietary antibody discovery platform is protected by a vast intellectual property portfolio, with 500 granted and pending patent applications relating to its platform technology and associated product pipeline. The Company has attracted multiple partnerships with biopharma targeting the significant unmet needs across several disease areas, including oncology, immunology, and CNS. F-star’s goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through its proprietary tetravalent, bispecific natural antibody (mAb²

™

) format,

F-star’s

mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format,

F-star

believes its proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding.

~~F-star’s~~

~~most advanced product candidate, FS118, is currently being evaluated in a~~

~~proof-of-concept~~

~~Phase 2 trial in~~

~~PD-1/PD-L1~~

~~quired resistance head and neck cancer patients. FS118 is a tetravalent mAb2 bispecific antibody targeting two receptors,~~

~~PD-L1~~

~~and~~

~~LAG-3,~~

both of which are established pivotal targets in immuno- oncology. F-star’s second product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity. F-star’s third product candidate, FS222, aims to improve outcomes in low PD-L1 expressing tumors and is a mAb2 bispecific antibody that is designed to target both the costimulatory CD137 and the inhibitory PD-L1 receptors, which are co-expressed in a number of tumor types. SB 11285 which F-star acquired pursuant to a business combination with Spring Bank Pharmaceuticals, Inc. (“Spring Bank”), is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers.

Share Exchange Agreement

On November 20, 2020,

F-star

Therapeutics, Inc., formerly known as Spring Bank Pharmaceuticals, Inc., completed a business combination (the “Transaction”) with

F-star

Therapeutics Limited

(“F-star

Ltd”) in accordance with the terms of the Share Exchange Agreement, dated July 29, 2020 (the “Exchange Agreement”), by and among the Company,

F-star

Ltd and certain holders of capital stock and convertible notes of

F-star

Ltd (each a “Seller”, and collectively with holders of

F-star

Ltd securities who subsequently became parties to the Exchange Agreement, the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of

F-star

Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Sellers that owned such

F-star

Ltd shares for a number of duly authorized, validly issued, fully paid and

non-assessable

shares of Company common stock pursuant to the exchange ratio formula set forth in the Exchange Agreement (the “Exchange Ratio”), rounded to the nearest whole share of Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, and prior to completion of, the Transaction, Spring Bank effected a

1-for-4

reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to

F-star

Therapeutics, Inc. Following the completion of the Transaction, the business of the Company became the business conducted by

F-star,

which is a clinical-stage immuno-oncology company focused on cancer treatment through its proprietary tetravalent bispecific antibody programs. Unless otherwise noted, all references to share amounts in this report reflect the Reverse Stock Split.

~~Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to~~

~~F-star~~

~~Ltd stockholders, based on an Exchange Ratio of 0.1125 shares of Spring Bank common stock for each~~

~~F-star~~

Ltd ordinary share, stock option and restricted stock unit (“RSU”) outstanding immediately prior to the Closing. The Exchange Ratio was determined through arms-length negotiations between Spring Bank and

~~F-star~~

~~Ltd pursuant to a formula set forth in the Exchange Agreement.~~

~~Table of Contents~~

~~Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in~~

~~F-star~~

~~Ltd purchased $15.0 million of~~

~~F-star~~

~~Ltd ordinary shares (the~~

~~“Pre-Closing~~

~~Financing”). These ordinary shares of~~

~~F-star~~

~~Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the same Exchange Ratio.~~

Pursuant to the Exchange Agreement, all outstanding options to purchase Spring Bank common stock were accelerated immediately prior to the Closing, and each outstanding option with an exercise price greater than the closing price of Spring Bank common stock on the date of the Closing (the “Closing Date”) was exercised in full, and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date.

~~Immediately following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the~~

~~F-star~~

Ltd stockholders beneficially owned approximately 53.7% of the combined Company’s common stock and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of the Company’s common stock outstanding. Concurrently with the execution of the Exchange Agreement, certain officers and directors of Spring Bank and

~~F-star~~

~~Ltd and certain stockholders of~~

~~F-star~~

~~Ltd entered into~~

~~lock-up~~

~~agreements, pursuant to which they agreed to certain restrictions on transfers of any shares of the Company’s common stock for the~~

~~180-day~~

~~period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of~~

~~F-star~~

~~Ltd subscribed for in the~~

~~Pre-Closing~~

~~Financing and pursuant to certain other limited exceptions.~~

~~In addition, at the Closing, Spring Bank,~~

~~F-star~~

Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, entered into a STING Agonist Contingent Value Rights Agreement (the “STING Agonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Agonist CVR Agreement, each

~~pre-Reverse~~

Stock Split share of Company common stock held by stockholders as of the record date on November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“CVR”)(“STING Agonist CVR”), payable on a

~~pre-Reverse~~

Stock Split basis, entitling such holders to receive, in connection with certain transactions involving the proprietary STING agonist compound designated as SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that resulted in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below), an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).

~~The CVR payment obligation expires on the later of 18 months following the Closing or the~~

~~one-year~~

anniversary of the date of the final database lock of the STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest, and are not registered with the Securities and Exchange Commission (the “SEC”) or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. The STING Agonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Agonist CVR Expiration Date or all CVR payment amounts are paid pursuant to their terms.

~~At the Closing, Spring Bank,~~

~~F-star~~

Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, also entered into a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Antagonist CVR Agreement, each share of common stock held by Spring Bank stockholders as of November 19, 2020, immediately prior to the Closing, received a dividend of one CVR (“STING Antagonist CVR”) entitling such holders to receive, in connection with the execution of a potential development agreement (the “Approved Development Agreement”) and certain other transactions involving proprietary STING antagonist compound occurring on or prior to the STING Antagonist CVR Expiration Date (as defined below) equal to 80% of all net proceeds (as defined in the STING Antagonist CVR Agreement) received by the Company after the Closing pursuant to (i) the Approved Development Agreement, if any, and (ii) all CVR Transactions (as defined in the STING Antagonist CVR Agreement) entered into prior to the STING Antagonist CVR Expiration Date.

The CVR payment obligations expire on the seventh anniversary of the Closing (the “STING Antagonist CVR Expiration Date”). The STING Antagonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest, and are not registered with the SEC or listed for trading on any exchange. Until the STING Antagonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) consummate the Approved Development Agreement, (b) to perform the terms of the Approved Development Agreement and (c) pursue CVR Transactions. The STING Antagonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Antagonist CVR Expiration Date or all CVR payment amounts are paid pursuant to their terms.

~~Table of Contents~~

The acquisition-date fair value of the CVR liability represents the future payments that are contingent upon the achievement of sale or licensing for the product candidates. The fair value of the contingent consideration acquired of $2.5 million as of December 31, 2020 and as of March 31, 2021 is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

~~All issued and outstanding~~

~~F-star~~

~~Ltd share options~~

~~ranted under~~

~~F-star’s~~

~~three legacy equity incentive plans became exercisable in full immediately prior to the Closing. At the Closing, all issued share options and restricted stock units granted by~~

~~F-star~~

~~Ltd under the~~

~~F-star~~

Therapeutics Limited 2019 Equity Incentive Plan (the “2019 Plan”) were replaced by options (“Replacement Options”) and awards (“Replacement RSUs”), on the same terms (including vesting), for Company common stock, based on the Exchange Ratio.

The Company’s common stock, which was listed on the Nasdaq Capital Market, traded through the close of business on Friday, November 20, 2020 under the ticker symbol “SBPH” and continued trading on the Nasdaq Capital Market, on a post-Reverse Stock Split adjusted basis, under the ticker symbol “FSTX” beginning on Monday, November 23, 2020. Commencing on November 23, 2020, the Company’s common stock was represented by a new CUSIP number, 30315R 107. After the Transaction, the Company had approximately $

~~million in cash. The combined company is now headquartered out of~~

~~F-star~~

~~Ltd’s existing facilities in Cambridge, United Kingdom and office in Cambridge, MA.~~

The Transaction was accounted for as a business combination using the acquisition method of accounting under the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Topic 805,

~~Business Combinations~~

~~(“ASC 805”). The Transaction was accounted for as a reverse acquisition with~~

~~F-star~~

~~Ltd being deemed the acquiring company for accounting purposes. Under ASC 805,~~

~~F-star~~

~~Ltd, as the accounting acquirer, recorded the assets acquired and liabilities assumed of Spring Bank in the Transaction at their fair values as of the acquisition date (see Note~~

~~of the financial statements).~~

~~F-star~~

Ltd was determined to be the accounting acquirer based on an analysis of the criteria outlined in ASC 805 and the facts and circumstances specific to the Transaction, including the fact that immediately following the Transaction:

~~(1) F-star~~

~~Ltd shareholders owned the majority of the voting rights of the combined company;~~

~~(2) F-star~~

~~Ltd designated a majority (five of eight) of the initial members of the board of directors of the combined company; and~~

~~(3) F-star~~

~~Ltd senior management held the key positions in senior management of the combined company. As a result, upon consummation of the Transaction, the historical financial statements of~~

~~F-star~~

~~Ltd became the historical financial statements of the combined organization.~~

Liquidity

On March 30, 2021, the Company entered into a Sales Agreement (the ~~“2021 Sales~~“Sales Agreement”) with SVB Leerink LLC (“SVB Leerink”) with respect to an

~~“at-the-market”~~

“at-the-market” offering as defined in Rule 415 of the Securities Act of 1933, as amended, under which the Company could offer and sell, from time to time in its sole discretion, shares of its common stock, par value ~~$0.0001~~$0.0001 per share, having an aggregate offering price of up to ~~$50.0~~$50.0 million through SVB Leerink as its sales agent. As of May 6, 2021, the Company had issued and sold 979,843 shares of common stock for gross proceeds of ~~$9.5~~$9.5 million, resulting in net proceeds of ~~$9.2~~$9.1 million after deducting sales commissions and offering expenses. On May 6, 2021, the Company terminated the Sales Agreement.

On August 13, 2021, the Company entered into a Sales Agreement (the “2021 Sales Agreement”) with SVB Leerink with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $50.0 million through

SVB Leerink as its sales agent. As of September 30, 2021 Company had 0t offered or sold any common stock under the 2021 Sales Agreement.

On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the underwriters, relating to an underwritten public offering (the “Underwritten Public Offering”) of ~~approximately 9.3~~10.4 million shares of the Company’s common stock, par value ~~$0.0001~~$0.0001 per share. The underwritten public offering resulted in gross proceeds of ~~$65.0~~$73.1 million. The Company incurred ~~$3.9~~$4.4 million in issuance costs and $0.5 million of professional fees associated with the underwritten public offering, resulting in net proceeds to the Company of ~~$61.1~~$68.2 million.

On April 1, 2021, the Company, as borrower, entered into a Venture Loan and Security Agreement (the “Loan and Security Agreement”) with Horizon Technology Finance Corporation (“Horizon”), as lender and collateral agent for itself. The Loan and Security Agreement provides for 4 ~~(4)~~ separate and independent $

2.5

million term loans (“Loan A”, “Loan B”, “Loan C”, and “Loan D”) (with each of Loan A, Loan B, Loan C and Loan D, individually a “Term Loan” and, collectively, the “Term Loans”), whereby, upon the satisfaction of all the conditions to the funding of the Term Loans, each Term Loan will be delivered by Horizon to the Company in the following manner: (i) Loan A was ~~to be~~ delivered by Horizon to the Company ~~prior to~~by April 1, 2021, (ii) Loan B was ~~required to be~~ delivered by Horizon to the Company ~~prior to~~by April 1, 2021, (iii) Loan C ~~is required to be~~was delivered by Horizon to the Company ~~prior to~~by June 30, 2021, and (iv) Loan D ~~is required to be~~was delivered by Horizon to the Company ~~prior to~~by June 30, 2021. The Company may only use the proceeds of the Term Loans for working capital or general corporate purposes as contemplated by the Loan and Security Agreement. On April 1, 2021, the Company drew down $

million. On June 22, 2021, the Company drew down another $5 million under this facility.

The Company has incurred significant losses and has an accumulated deficit of

~~57.0~~

83.2 million as of ~~March 31,~~September 30, 2021.

F-star

expects to incur substantial losses in the foreseeable future as it conducts and expands its research and development activities and clinical trial activities. As of ~~May 17,~~September 30, 2021, the Company had cash of $71.1 million and working capital of $67.3 million. As of November 10, 2021, the date of issuance of the condensed consolidated financial statements, ~~after proceeds from the ATM, Sales Agreement and drawdown of the Term Loans,~~ the Company’s cash ~~of approximately~~

~~76.3~~

~~million~~and cash equivalents on hand will be sufficient to fund its current operating plan and planned capital expenditures for at least the next 12 months.

The Company may continue to seek additional funding through public equity, private equity, debt financing, collaboration partnerships, or other sources. There are no assurances, however, that the Company will be successful in raising additional working capital, or if it is able to raise additional working capital, it may be unable to do so on commercially favorable terms. The Company’s failure to raise future capital or enter into other such arrangements if and when needed would have a negative impact on its business, results of operations and financial condition and its ability to develop its product candidates.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”).

and the rules and regulations of the Securities Exchange Commission ("SEC") for interim financial statements.

The accompanying interim condensed consolidated financial statements as of ~~March 31,~~September 30, 2021, and for the three and nine months ended ~~March 31,~~September 30, 2021 and 2020, and ~~related interim~~ information contained within the notes to ~~the~~these condensed consolidated financial statements, are unaudited. ~~In management’s opinion, the~~These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s audited annual financial statements and ~~include~~in management's opinion contain all ~~adjustments~~adjustrevisionments (including normal recurring adjustments) necessary for the fair presentation of the Company’s financial position as of ~~March 31,~~September 30, 2021, results of operations for the three and nine months ended ~~March 31,~~September 30, 2021 and 2020, statement of stockholders’ equity for the three and nine months ended ~~March 31,~~September 30, 2021 and 2020 and its cash flows for the ~~three~~nine months ended ~~March 31,~~September 30, 2021 and 2020. These interim condensed consolidated financial statements should be read in conjunction with the Company’s annual audited financial statements and ~~accompanying~~ notes ~~contained~~thereto included in the Company’s Annual Report filed on SEC Form 10-K for the year ended December 31, 2020. The results for the three and nine months ended ~~March 31,~~September 30, 2021, are not necessarily indicative of the results expected for the full fiscal year or any interim period.

Revision of Previously Issued Financial Statements

In September 2021, the Company identified an error in its accounting treatment for research and development expenses. This error resulted in an overstatement of research and development expenses for the first six months of 2021 and accrued expenses and other current liabilities as of March 31, 2021 and June 30, 2021. The Company assessed the materiality of this error on prior period financial statements in accordance with the SEC Staff Accounting Bulletin Number 99, Materiality, and ASC 250-10, Accounting Changes and Error Corrections. The Company determined that this error was not material to the financial statements of any prior interim period. To correct the immaterial misstatement, the Company decreased accumulated deficit by $0.3 million as of June 30, 2021.

Principles of Consolidation

The Company’s interim condensed consolidated financial statements have been prepared in conformity with U.S. GAAP. Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the ASC and Accounting Standards Updates (“ASU”) of the FASB. The accompanying condensed consolidated financial statements include the accounts of F-star Therapeutics, Inc. and its wholly owned subsidiaries. All ~~intercompany~~inter-company balances and transactions between the consolidated companies have been eliminated in consolidation.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting years. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the fair value of the assets and liabilities acquired in the transaction between Spring Bank and

F-star

Ltd

~~Table of Contents~~

fair value of the convertible loan containing embedded derivatives, the fair value of contingent value rights, the accrual for research and development expenses, revenue recognition, fair values of acquired intangible assets and impairment review of those assets, warrants, share based compensation expense, and income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates

re are periodically reviewed in light of reasonable changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates or assumptions.

Concentrations of credit risk and of significant suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash and cash equivalents in financial institutions in amounts that could exceed government-insured limits. The Company does not believe it is subject to additional credit risks beyond those normally associated with commercial banking relationships.

The Company is dependent on contract research organizations to provide its clinical trials and third-party manufacturers to supply products for research and development activities in its programs. In particular, the Company relies and expects to continue to rely on a small number of manufacturers to supply its requirements for

supplies and raw materials related to these programs. These programs could be adversely affected by a significant interruption in these manufacturing services or the availability of raw materials.

Property, plant and equipment

Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation expense is recognized using the straight-line method over the estimated useful lives of the respective assets as follows:


		Estimated Useful Economic Life
Leasehold property improvements, right of use assets		Lesser of lease term or useful life
Laboratory equipment		5 years
Furniture and office equipment		3 years

~~Leases~~

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in

right-of-use

(“ROU”) assets, and lease obligations in the Company’s consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. This is the rate the Company would have to pay if borrowing on a collateralized basis over a similar term to each lease. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Impairment of Long-Lived Assets

Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If the undiscounted cash flows are insufficient to recover the carrying value, an impairment loss is recorded for the difference between the carrying value and fair value of the asset. As of ~~March 31,~~September 30, 2021, 0

such impairment has been recorded.

License and collaboration arrangements and revenue recognition

The Company’s revenues are generated primarily through license and collaboration agreements with pharmaceutical and biotechnology companies. The terms of these arrangements may include (i) the grant of intellectual property rights (IP licenses) to therapeutic drug candidates against specified targets, developed using the Company’s proprietary ~~mAb2~~mAb2 bispecific antibody platform, (ii) performing research and development services to optimize drug candidates, and (iii) the grant of options to obtain additional research and development services or licenses for additional targets, or to optimize product candidates, upon the payment of option fees.

The terms of these arrangements typically include payment to the Company of one or more of the following:

non-refundable,

upfront license fees; payments for research and development services; fees upon the exercise of options to obtain additional services or licenses; payments based upon the achievement of defined collaboration objectives; future regulatory and sales-based milestone payments; and royalties on net sales of future products.

The Company has adopted FASB ASC Topic 606,

Revenue from Contracts with Customers

(“ (“ASC 606”). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. To date, the Company has entered into License and Collaboration Agreements with Denali ~~and~~Therapeutics, Inc. (“Denali”), Ares ~~(an~~Trading S.A. (“Ares,”)

an affiliate of Merck KGaA, Darmstadt, Germany) and in July 2021 with AstraZeneca AB ("AstraZeneca"), which were determined to be within the scope of ASC 606.

Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized under ASC 606, the Company performs the following steps: (i) identification of the promised goods or services in the contract; (ii) determination as to whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. As part of the accounting for these arrangements, the Company must make significant judgments, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each performance obligation.

Once a contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within the contract and determines those that are performance obligations. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, they are considered performance obligations.

Performance obligations are promised goods or services in a contract to transfer a distinct good or service to the customer. The promised goods or services in the Company’s contracts with customers primarily consist of license rights to the Company’s intellectual property for research and development, research and development services, options to acquire additional research and development services, and options to obtain additional licenses, such as a commercialization license for a potential product candidate. Promised goods or services are considered distinct when: (i) the customer can benefit from the good or service on its own or together with other readily available resources; and (ii) the promised good or service is separately identifiable from other promises in the contract.

In assessing whether promised goods or services are distinct, the Company considers factors such as the stage of development of the underlying intellectual property, the capabilities of the customer to develop the intellectual property on their own and whether the required expertise is readily available. In addition, the Company considers whether the collaboration partner can benefit from a promise for its intended purpose without the receipt of the remaining promises, whether the value of the promise is dependent on the unsatisfied promises, whether there are other vendors that could provide the remaining promises, and whether it is separately identifiable from the remaining promises. The Company estimates the transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of each arrangement that includes variable consideration, the Company evaluates the amount of the potential payments and the likelihood that the payments will be received. The Company utilizes either the most likely amount method or expected value method to estimate variable consideration to include in the transaction price based on which method better predicts the amount of consideration expected to be received. The amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company

~~re-evaluates~~

the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative

~~catch-up~~

~~basis in the period of adjustment.~~

After the transaction price is determined, it is allocated to the identified performance obligations based on the estimated standalone selling price. The Company must develop assumptions that require judgment to determine the standalone selling price for each performance obligation identified in the contract. The Company utilizes key assumptions to determine the standalone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction, probabilities of technical and regulatory success and the estimated costs. Certain variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amounts the Company would expect to receive for each performance obligation.

The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time based on the use of an input method. The Company accounts for contract modifications as a separate contract if both of the following conditions are met:

~~(i)~~

~~the scope of the contract increases because of the addition of promised goods or services that are distinct; and~~

~~Table of Contents~~

~~(ii)~~

the price of the contract increases by an amount of consideration that reflects standalone selling prices of the additional promised goods or services and any appropriate adjustments to that price to reflect the circumstances of the particular contract.

If a contract modification is deemed to not be a separate contract, then the transaction price is updated and allocated to the remaining performance obligations (both from the existing contract and the modification). Previously recognized revenue for goods and services that are not distinct from the modified goods or services is adjusted based upon an updated measure of progress for the partially satisfied performance obligations.

If a contract modification is deemed to be a separate contract, any revenue recognized under the original contract is not retrospectively adjusted and any performance obligations remaining under the original contract continue to be recognized under the terms of that contract.

~~The Company’s collaboration revenue arrangements include the following:~~

~~Up-front~~

~~License Fees: If a license is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from nonrefundable,~~

~~up-front~~

fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from

~~non-refundable,~~

~~up-front~~

~~fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.~~

Milestone payments: The Company’s collaboration agreements may include development and regulatory milestones. The Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. The Company evaluates factors such as the scientific, clinical, regulatory, commercial, and other risks that must be overcome to achieve the particular milestone in making this assessment. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company

~~re-evaluates~~

~~the probability of achievement of such milestones and any related constraint, and if necessary, adjusts the estimate of the overall transaction price. Any such adjustments are recorded on a cumulative~~

~~catch-up~~

~~basis, which would affect collaboration revenue and net loss in the period of adjustment.~~

Customer Options: The Company evaluates the customer options to obtain additional items (i.e., additional license rights) for material rights, or options to acquire additional goods or services for free or at a discount. Optional future services that reflect their standalone selling prices do not provide the customer with a material right and, therefore, are not considered performance obligations and are accounted for as separate contracts. If optional future services include a material right, they are accounted for as performance obligations. The Company determines an estimated standalone selling price of any material rights for the purpose of allocating the transaction price. The Company considers factors such as the identified discount and the probability that the customer will exercise the option. Amounts allocated to a material right are not recognized as revenue until, at the earliest, the option is exercised or expires.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on a level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any revenue related to sales-based royalties or milestone payments based on the level of sales.

Research and Development Services: The promises under the Company’s collaboration agreements may include research and development services to be performed by the Company on behalf of the partner. Payments or reimbursements resulting from the Company’s research and development efforts are recognized as the services are performed and presented on a gross basis because the Company is the principal for such efforts.

Research and development costs

Research and development costs are expensed as incurred. Research and development expenses are comprised of costs incurred in performing research and development activities, including compensation expense, share-based compensation and benefits, facilities costs and laboratory supplies, depreciation, amortization and impairment expense, manufacturing expenses and external costs of outside vendors engaged to conduct preclinical development activities and clinical trials as well as the cost of licensing technology. Typically, upfront payments and milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred, except for payments relating ~~for~~to intellectual property rights with future alternative use which will be expensed when the intellectual property is in use. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

~~Table of Contents~~

Warrants

The Company accounts for warrants within stockholders equity or as liabilities based on the characteristics and provisions of each instrument. The Company evaluates outstanding warrants in accordance with ASC 480, Distinguishing Liabilities from Equity, and ASC 815, Derivatives and ~~Hedging.~~Hedging. If none of the criteria in the evaluation in these standards are met, the warrants are classified as a component of stockholders’ equity and initially recorded at their grant date fair value without subsequent remeasurement. Warrants that meet the criteria are classified as liabilities and remeasured to their fair value at the end of each reporting period.

Stock-Based Compensation

The Company accounts for share-based compensation in accordance with ASC 718, “Compensation – Stock Compensation”(“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s consolidated statements of operations and comprehensive loss.

~~The Company records the expense for option awards using a graded vesting method. The Company accounts for forfeitures as they occur. For share-based awards granted to~~

~~non-employee~~

~~consultants, the measurement date for~~

~~non-employee~~

~~awards is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award.~~

The Company reviews stock award modifications when there is an exchange of original award for a new award. The Company calculates for the incremental fair value based on the difference between the fair value of the modified award and the fair value of the original award immediately before it was modified. The Company immediately recognizes the incremental value as compensation cost for vested awards and recognizes, on a prospective basis over the remaining requisite service period, the sum of the incremental compensation cost and any remaining unrecognized compensation cost for the original award on the modification date.

The fair value of stock options (“options”) on the grant date is estimated using the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including the option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award.

~~Historically, given the absence of an active market for the ordinary shares of~~

~~F-star~~

Ltd, the board of directors determined the estimated fair value of the Company’s equity instruments based on input from management, which utilized the most recently available independent third-party valuation, and considered a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector. Each valuation methodology included estimates and assumptions that require judgment. These estimates and assumptions included a number of objective and subjective factors in determining the value of

~~F-star~~

Ltd ordinary shares at each grant date. The expected volatility for F star Ltd was calculated based on reported volatility data for a representative group of publicly traded companies for which historical information was available. The historical volatility was calculated based on a period of time commensurate with the assumption used for the expected term. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption.

~~F-star~~

~~Ltd used the simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the end of the contractual term.~~

~~F-star~~

~~Ltd utilized this method due to the lack of historical exercise data and the plain nature of its share-based awards.~~

~~The Company uses the remaining contractual term for the expected life of~~

~~non-employee~~

~~awards. The expected dividend yield is assumed to be zero, as the Company has never paid dividends and has no current plans to pay any dividends.~~

The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Fair value measurements of financial instruments

The Company’s financial instruments consist of cash, accounts payable, CVRs and liability classified warrants. The carrying amounts of cash and accounts payable approximate their fair value due to the short-term nature of those financial instruments. The fair value of CVRs and the liability classified warrants are remeasured to fair value each reporting period.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC Topic 820,

~~Fair Value Measurement~~

(“ASC 820”), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances.

~~Table of Contents~~

ASC 820 identifies fair value as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a three-tier fair value hierarchy that distinguishes between the following:

~~Level 1 — Quoted prices in active markets for identical assets or liabilities.~~

Level 2 — Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

Level 3 — Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents, and other current assets, research and development incentives receivable, accounts payable and accrued liabilities and other current liabilities approximate their fair values, due to their short-term nature.

Net loss per share

The Company computes net loss per share in accordance with ASC Topic 260,

Earnings Per Share

(“ (“ASC 260”) and related guidance, which requires two calculations of net (loss) income attributable to the Company’s shareholders per share to be disclosed: basic and diluted. Convertible preferred shares are considered participating securities and are included in the calculation of basic and diluted net (loss) income per share using the

two-class

method. In periods where the Company reports net losses, such losses are not allocated to the convertible preferred shares for the computation of basic or diluted net (loss) income.

Diluted net (loss) income per share is the same as basic net (loss) income per share for the periods in which the Company had a net loss because the inclusion of outstanding common stock equivalents would be anti-dilutive.

Income taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the

consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. ~~Potential for~~The potential recovery of deferred tax assets is evaluated by estimating the potential for future taxable profits, ~~expected~~if any.

2. Business Combination

As described in Note 1, on November 20, 2020,

F-star

Ltd completed a business combination with Spring Bank. For accounting purposes, the purchase price was based on (i) the fair value of Spring Bank common stock as of the Transaction date of ~~$21.5~~$21.5 million, which was determined based on the number of shares of common stock issued in connection with the Transaction, and (ii) the portion of the fair value attributable to

in-the-money

fully and partially vested stock options and warrants.

Under the acquisition method of accounting, the total purchase price is allocated to the acquired tangible and intangible assets and assumed liabilities based on their fair values as of the acquisition date. Any excess purchase price over the fair value of assets acquired and liabilities assumed is allocated to goodwill. Acquired

~~in-process~~

~~research and development assets will be classified as indefinite-lived intangible assets and will be amortized over their estimated useful economic lives when put into use. The fair values of acquired~~

~~in-process~~

research and development assets were calculated using an income approach based on the expected future cash flows associated with the respective asset using an estimated discount rate of 14%. In addition, on the date of the Transaction, there were 73,337 outstanding equity classified warrants with a fair value of $0.2 million and 408,444 outstanding liability classified warrants with a fair value of $0.2 million.

~~Goodwill is allocated to one reporting unit. The goodwill was primarily attributable to the access~~

~~F-star~~

~~gained to a public listing on the Nasdaq Capital Market. The Company determined that the underlying goodwill and intangible assets are not deductible for tax purposes.~~

~~For the year ended December 31, 2020, the Company incurred acquisition-related expenses of approximately $4.2 million, which are included in general and administrative expenses.~~

The purchase price is allocated to the fair value of assets and liabilities acquired as follows in the table below (in thousands, except shares of common stock and fair value per share):

~~6. Warrants~~

In connection with Spring Bank’s initial public offering (“IPO”) in 2016, there was an issuance of warrants to the sole book-running manager to purchase 7,087 shares of common stock. The warrants were exercisable at an exercise price of $60.00 per share and expired on May 5, 2021. The Company evaluated the terms of the warrants and concluded that they should be equity-classified. At March 31, 2021 there were 7,087 warrants outstanding.

During 2016, Spring Bank entered into a definitive agreement with respect to the private placement of 411,184 shares of common stock and warrants to purchase 411,184 shares of common stock (the “November 2016 Private Placement Warrants”) to a group of accredited investors. The November 2016 Private Placement Warrants are exercisable at an exercise price of $43.16 per share and expire on November 23, 2021. The Company evaluated the terms of these warrants and concluded that they are liability-classified. The Company must recognize any change in the value of the warrant liability each reporting period in the statement of operations and comprehensive loss. As of March 31, 2021, the fair value of the November 2016 Private Placement Warrants was approximately $11,000 and 388,451 warrants have been exercised to date. At March 31, 2021, there were 19,993 warrants outstanding.

During 2019, Spring Bank entered into a loan agreement with Pontifax Medison Finance (Israel) L.P. and Pontifax Medison Finance (Cayman) L.P., as lenders, and Pontifax Medison Finance GP, L.P., pursuant to which Spring Bank issued to the lenders warrants to purchase 62,500 shares of common stock (the “Pontifax Warrants”). The Pontifax Warrants are exercisable at $8.32 per share and expire on September 19, 2025. The Company evaluated the terms of the warrants and concluded that they should be equity-classified. At March 31, 2021, there were 62,500 warrants outstanding.

During 2019, Spring Bank issued warrants to a service provider to purchase 3,750 shares of common stock (the “September 2019 Warrants”). The September 2019 Warrants are exercisable at an exercise price of $16.84 per share and expire on September 19, 2021. The Company evaluated the terms of the warrants and concluded that they should be equity-classified. At March 31, 2021, there were 3,750 warrants outstanding.

~~A summary of the warrant activity for the three months ended March 31, 2021 is as follows:~~


	~~Warrants~~
~~Outstanding at December 31, 2020~~		~~144,384~~

7.	~~Stock Option Plans~~

~~Incentive Plans~~

~~On June 14, 2019, as part of a group restructuring, the~~

~~F-star~~

Ltd board of directors and shareholders approved the 2019 Plan. The initial maximum number of ordinary shares that could be issued under the 2019 Plan was 2,327,736. This number consisted of 1,922,241 new ordinary shares and 405,495 new ordinary shares as replacements for grants under the previous

~~F-star~~

~~group entities’ legacy share option schemes (the~~

~~F-star~~

~~Alpha Limited Share Option Scheme, the~~

~~F-star~~

~~Beta Share Option Scheme and the GmbH~~

~~F-star~~

~~EMI Share Option Scheme). In addition, the GmbH Employee Share Option Plan was transferred to~~

~~F-star~~

Ltd from GmbH. This plan grants the beneficiaries participation rights only, beneficiaries would receive a proportion of the exit proceeds realized by shareholders, but the plan does not grant the right to purchase shares. The transfer of the participation rights occurred at the same exchange ratio as used for the exchange of GmbH shares for shares issued by

~~F-star~~

~~Ltd.~~

~~Table of Contents~~

~~Awards granted under the 2019 Plan generally vest over a~~

four-year service period with 28% of the award vesting on the first anniversary of the commencement date and the balance vesting monthly over the remaining three years. Awards generally expire 10 years from the date of the grant. For certain senior members of management and directors, the board of directors approved an alternative vesting schedule.

~~As result of the Transaction, the share reserve automatically increased on January 1~~

of the year following the year in which a Nasdaq listing occurred, in an amount equal to 4% of the total number of shares outstanding as of December 31 of the preceding year. As a result, there were additional 364,005 shares to be issued for the 2019 plan. As of March 31, 2021, there were 67,986 shares available for issuance under the 2019 Plan.

~~In conjunction with the Transaction, all issued and outstanding~~

~~F-star~~

~~Ltd share options granted under the three~~

~~F-star~~

~~Ltd legacy equity incentive plans became exercisable in full immediately prior to the Closing. At the Closing, all issued share options and RSUs granted by~~

~~F-star~~

Ltd under the 2019 Plan were replaced by the Replacement Options and Replacement RSUs on the same terms (including vesting), for Company common stock, based on the Exchange Ratio. The Company determined that the exchange of

~~F-star~~

Ltd awards for the Company awards would be accounted for as a modification of awards under ASC 718. The Company concluded that the modification would not affect the number of awards expected to vest or the service period over which compensation expense related to awards would be recognized, since the vesting schedule applicable to each Replacement Option would be the same as the vesting schedule applicable to the original option that it replaced. In addition, the Replacement RSUs and Replacement Options are subject to substantially the same terms and conditions as the original RSUs and original options, respectively, and did not provide holders of the Replacement Options or Replacement RSUs with any additional benefits that the holders did not have under their original options or original RSUs. In addition, the fair value of an award tranche immediately after modification was less than the fair value of that award tranche immediately before modification. Therefore, total compensation cost recognized for the Replacement RSUs and Replacement Options equaled the grant-date fair value of the original awards, and the Company continues to recognize the grant date fair values of the modified awards over their respective service periods.

~~Amended and Restated 2015 Stock Incentive Plan~~

In March 2018, the Spring Bank board of directors approved Spring Bank’s Amended and Restated 2015 Stock Incentive Plan (the “Amended and Restated 2015 Plan” and, together with the Spring Bank’s 2014 Stock Incentive Plan (the “2014 Plan), the “Stock Incentive Plans”). Upon receipt of stockholder approval at Spring Bank’s 2018 annual meeting in June 2018, Spring Bank’s 2015 Stock Incentive Plan was amended and restated in its entirety, increasing the authorized number of shares of common stock reserved for issuance by 800,000 shares. Pursuant to the Amended and Restated 2015 Plan, there are 1,666,863 shares authorized for issuance. In addition, to the extent any outstanding awards under the 2014 Plan expire, terminate, or are otherwise surrendered, cancelled or forfeited after the closing of Spring Bank’s IPO, those shares are added to the authorized shares under the Amended and Restated 2015 Plan. The total number of shares authorized for issuance under both the 2014 Plan and the Amended and Restated 2015 Plan is 2,300,000.

Pursuant to the Exchange Agreement, all outstanding options to purchase Company common stock were accelerated immediately prior to the Closing and each outstanding option with an exercise price less than the trading price of the Company common stock as of the close of trading on the Closing Date was exercised in full and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date. As of March 31, 2021, the Company had 268,363 shares available for issuance under the Amended and Restated 2015 Plan.

~~Stock option valuation~~

~~The fair value of stock option grants is estimated using the Black-Scholes option-pricing model with the following assumptions:~~

March 31,

December 31

2021

2020
Risk-free interest rate
   0.36 % 0.17%-0.42%
Expected volatility
   87.8 % 82.8%-98.3%
Expected dividend yield
   0 % 0%
Expected life (in years)
   5.1 5.1

~~Expected Term~~

~~—The expected term represents management’s best estimate for the options to be exercised by option holders.~~

~~Volatility~~

~~—Since~~

~~F-star~~

Ltd did not have a trading history for its common stock, the expected volatility was derived from the historical stock volatilities of comparable peer public companies within its industry, whose businesses were considered to be comparable to that of

~~F-star~~

Ltd, over a period equivalent to the expected term of the share-based awards. After the Closing of the Transaction, the volatility of the Company’s Common Stock is used to determine volatility of the share-based awards at grant date.

~~Risk-Free Interest Rate~~

~~—The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant for~~

~~zero-coupon~~

~~U.S. Treasury notes with maturities approximately equal to the share-based awards’ expected term.~~

~~Dividend Rate~~

~~—The expected dividend is zero, as the Company has not paid nor does it anticipate paying any dividends on its common stock in the foreseeable future.~~

~~Table of Contents~~

~~Fair Value of Common Stock~~

~~— Prior to the Transaction,~~

~~F-star~~

Ltd estimated fair value used three different methodologies: the income approach, the market approach, and cost approach. The income approach uses the estimated present value of economic benefits. The market approach exams observable market values for similar assets or securities. The cost approach uses the concept of replacement cost as an indicator of value and the notion that an investor would pay no more for an asset that what it would cost to replace the asset with one of equal utility. After the Closing of the Transaction, the fair value of the Company’s Common Stock is used to estimate the fair value of the share-based awards at grant date.

~~License and collaboration agreement with Denali Therapeutics Inc.~~

~~Summary~~

~~In August 2016, Biotechnology,~~

~~F-star~~

~~Gamma Limited (a related party until May 30, 2018)~~

~~(“F-star~~

Gamma”), and GmbH entered into a license and collaboration agreement (the “Denali LCA”) with Denali. The goal of the collaboration was the development of certain constant Fc domains of an antibody with

~~non-native~~

~~antigen binding activity (“Fcabs”), to enhance delivery of therapeutics across the blood brain barrier into the brain. The collaboration was designed to leverage~~

~~F-star~~

Gamma’s modular antibody technology and Denali’s expertise in the development of therapies for neurodegenerative diseases. In connection with the entry into the collaboration agreement, Denali also purchased from the

~~F-star~~

~~Gamma shareholders an option, which was referred to as the~~

~~buy-out-option,~~

~~to acquire all of the outstanding shares of~~

~~F-star~~

~~Gamma pursuant to a~~

~~pre-negotiated~~

~~share purchase agreement.~~

~~On May 30, 2018, Denali exercised such~~

~~buy-out~~

~~option and entered into a share purchase agreement (the “Purchase Agreement”) with the shareholders of~~

~~F-star~~

~~Gamma and Shareholder Representative Services LLC, pursuant to which Denali acquired all of the outstanding shares of~~

~~F-star~~

~~Gamma (the “Acquisition”).~~

~~As a result of the Acquisition,~~

~~F-star~~

~~Gamma has become a wholly owned subsidiary of Denali and Denali changed the entity’s name to Denali BBB Holding Limited. In addition, Denali became a direct licensee of certain of~~

~~F-star’s~~

~~intellectual property (by way of Denali’s assumption of~~

~~F-star~~

~~Gamma’s license agreement with Biotechnology (the~~

~~“F-star~~

~~Gamma License”)). Denali made initial exercise payments to Biotechnology and the former shareholders of~~

~~F-star~~

~~Gamma under the Purchase Agreement and the~~

~~F-star~~

~~Gamma License, in the aggregate, of $18.0 million, less the net liabilities of~~

~~F-star~~

Gamma, which were approximately $0.2 million. $4.0 million was payable to the Company. In addition, Denali is required to make future contingent payments, to the Company and the former shareholders of

~~F-star~~

Gamma, with a maximum aggregate of $437.0 million upon the achievement of certain defined preclinical, clinical, regulatory, and commercial milestones. Of this total, a maximum of $91.4 million is payable to the Company. The total amount of the contingent payments varies, based on whether the Company delivers an Fcab that meets

~~pre-defined~~

~~criteria and whether the Fcab has been identified solely by the Company or solely by Denali or jointly by the Company and Denali.~~

Under the terms of the Denali LCA, Denali was granted the right to nominate up to three Fcab targets for approval (“Accepted Fcab Targets”), within the first three years of the date of the agreement. Upon entering into the Denali LCA, Denali had selected transferrin receptor as the first Accepted Fcab Target and paid an upfront fee of $5.5 million to

~~F-star~~

Gamma, which included selection of the first Accepted Fcab Target. In May 2018, Denali exercised its right to nominate two additional Fcab targets and identified a second Accepted Fcab Target. Denali made a

~~one-time~~

~~payment to the~~

~~F-star~~

~~group for the two additional Accepted Fcab Targets of $6.0 million and extended the time period for its selection of the third Accepted Fcab Target until August 2020.~~

~~Denali also agreed to be responsible for certain research costs incurred by~~

~~F-star~~

~~in conducting activities under each agreed development plan for up to 24 months.~~

~~Under the terms of the Denali LCA,~~

~~F-star~~

Gamma was prohibited from developing, commercializing and manufacturing any antibody or other molecule that incorporated any Fcab directed to an Accepted Fcab Target, or any such Fcab as a standalone product, and from authorizing any third party to take any such action.

~~Revenue recognition~~

The Company has considered the performance obligations identified in the contracts and concluded that the grant of intellectual property rights is not distinct from the provision of R&D services, as the R&D services are expected to significantly modify the early-stage intellectual property. As a result, the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for this contract.

~~Table of Contents~~

The initial transaction price for first Accepted Fcab Target was deemed to be $7.1 million consisting of $5.0 million for the grant of intellectual property rights and $2.1 million for R&D services, and $5.1 million for the second Accepted Fcab Target consisting of $3.0 million for the grant of intellectual property rights and $2.1 million for R&D services. During the year ended December 31, 2019, the transaction price for the first Accepted Fcab was increased to $6.6 million due to achievement of a $1.5 million milestone that on initial recognition of the contract was not included in the transaction price, as it was not deemed probable that a reversal would not occur in a future reporting period.

~~All performance obligations in respect of the first Accepted Fcab Target identified in the contract were deemed to have been fully satisfied during the year ended December 31, 2019.~~

~~During the three months ended March 31, 2021 and 2020, the Company recognized $0.1 million and $0.5 million, respectively, over time in respect of the second Accepted Fcab target.~~

~~2019 License and collaboration agreement with Ares Trading S.A.~~

In June 2017, Delta entered into an LCA and an Option Agreement with Ares (the “Ares LCA”). The purpose of the Ares LCA was for the companies to collaborate on the development of tetravalent bispecific antibodies against five drug target pairs. The Option Agreement granted Ares a call option to acquire the entire issued share capital of Delta. Under the Ares LCA, Delta was obligated to use commercially reasonable efforts to perform research and development activities on the five selected target pairs, under mutually agreed research plans. The activities were governed by a joint steering committee formed by an equal number of representatives from both parties.

On May 14, 2019, the Ares LCA agreement with Ares was amended and restated to convert the existing purchase option over the entire share capital of Delta to an intellectual property licensing arrangement that included the exclusive grant of development and exploitation rights to one tetravalent bispecific antibody directed against immuno-oncology targets and the option to acquire the exclusive right to an additional antibody. As part of the amended Ares LCA, Delta gained exclusive rights to FS118, now

~~F-star’s~~

~~lead product candidate, which is currently in a~~

~~proof-of-concept~~

~~clinical trial. As discussed further below, this amended and restated Ares LCA was accounted for a separate contract, rather than a contract amendment.~~

For the exclusive rights granted in relation to the first molecule, an option fee of $11.1 million was paid by Ares to Delta. Following receipt of the option fee, Ares becomes responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Company upon achievement of specified events. Delta is eligible to receive $71.6 million in development milestones and $83.9 million in regulatory milestones.

For the second antibody included within the amended and restated agreement, Delta is obliged to perform research activities under plans agreed by both parties. Ares will pay for all R&D costs half-yearly in advance until the company delivers the data package specified in the research plan. Ares can then elect to pay a fee of $14.0 million to exercise their option to take an exclusive intellectual property license, which allows them to control the development and exploitation of the molecule. Following receipt of the option fee, Ares is responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Delta upon achievement of specified events. Delta is eligible to receive $48.7 million in development milestones and $61.6 million in regulatory milestones.

Development milestone payments are triggered upon achievement by each product candidate of a defined stage of clinical development and regulatory milestone payments are triggered upon approval to market a product candidate by the U.S. Food and Drug Administration or other global regulatory authorities. Sales-based milestones are payable based upon aggregate annual worldwide net sales in all indications of all licensed products. Delta is eligible to receive $168.0 million in sales-based milestones. In addition, to the extent that any product candidates covered by the exclusive licenses granted to Ares are commercialized, Delta will be entitled to receive a single digit royalty based on a percentage of net sales on a

~~country-by-country~~

~~basis.~~

On July 15, 2020, a deed of amendment (the “2020 Amendment”) was enacted in respect of the May 13, 2019, amendment to the Ares LCA. The 2020 Amendment had two main purposes (i) to grant additional options to acquire intellectual property rights for a further two molecules; and (ii) to allow Ares to exercise its option early to acquire intellectual property rights to the second molecule included in the agreement as well as to terminate the R&D services.

~~Revenue recognition~~

Management has considered the performance obligations identified in the contracts and concluded that the option for the grant of intellectual property rights is not distinct from the provision of R&D services in the agreements, as the R&D services are expected to significantly modify the early-stage intellectual property. As a result, the option for the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for all molecules under the original contract and each individual molecule included in the May 13, 2019 amendment to the Ares LCA. The Company recognizes revenue using the

~~cost-to-cost~~

~~method, which it believes best depicts the transfer of control of the services to the customer. Under the~~

~~cost-to-cost~~

~~method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation.~~

All performance obligations in the original Ares LCA were deemed to have been fully satisfied on termination of the original Ares LCA on May 13, 2019, and no further revenue is expected to be recognized. The total transaction price for the Ares LCA, as amended, was initially determined to be $15.4 million, consisting of the upfront payment and research and development funding for the research term. Variable consideration to be paid to the company upon reaching certain milestones had been excluded from the calculation, as at the inception of the contract, it was not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period.

~~Table of Contents~~

There were two components identified in the 2020 Amendment, each of which was accounted for as a separate performance obligation. The grant of the additional options to acquire intellectual property rights was deemed to be distinct, as the customer can benefit from it on its own, and it is independent of the delivery of other performance obligations in the original contract. Additionally, as the amount of consideration reflects a standalone selling price, the Company determined that the second component is accounted for as a separate contract.

~~In the three months ended March 31, 2021, $0.9 million was recognized in relation to the first antibody included in the 2020 Amendment.~~

The second component that allows the customer to exercise its option to acquire intellectual property rights early is considered to be a modification of the original contract, as the option is not independent of the R&D services provided under the original contract, and therefore the goods and services are not distinct. The Company updated the transaction price and measure of progress for the performance obligation relating to this molecule.

As a result of the 2020 Amendment, the maximum amount payable by Ares on the achievement of certain development and regulatory milestones in the aggregate was increased to $479.3 million, and the maximum amount payable on the achievement of certain commercial milestones was increased to $295.7 million.

In the three months ended March 31, 2021, Ares provided notice of its intention to exercise its option granted under the 2020 Amendment to acquire the intellectual property rights for an additional molecule. $2.7 million was recognized at a point in time in respect of the option exercise.

10. Stock Option Plans

Incentive Plans

The Company maintains two equity incentive plans (the "Plans") that provide for the granting of stock options, share appreciation rights, restricted shares, restricted share units, performance share units and certain other share based awards as provided in the Plans to certain employees, members of the board of directors, consultants or other service providers of the Company, with a prescribed contractual term not to exceed ten years. As of September 30, 2021, there were 196,910 shares of common stock available for grant under the Plans. Awards granted under the Plans generally vest over a four-year period with 25% or 28% of the award vesting on the first anniversary of the commencement date and the balance vesting monthly over the remaining three years. Grants are generally awarded with a contractual terms of 10 years from the date of the grant. For certain senior members of management and directors, the board of directors approved an alternative vesting schedule. The share reserve under one of the Plans automatically increases on January 1st each year, in an amount equal to 4% of the total number of shares outstanding as of December 31 of the preceding year.

2019 License and collaboration agreement with Ares Trading S.A.

Summary

On May 13, 2019, the Company entered into a licensing and collaboration agreement ("2019 LCA") with Ares, pursuant to which the Company granted the option to enter into a worldwide, exclusive license to certain patents and know-how to develop, manufacture and commercialize two separate mAb2 antibody products that each contain a specific Fcab and a Fab target pair (each a licensed product).

For the exclusive rights granted in relation to the first molecule, an option fee of $11.1 million was paid by Ares to the Company. Following receipt of the option fee, Ares became responsible for the development of the molecule and development, regulatory and sales-based royalties become payable to Company upon achievement of specified events.

On July 15, 2020, a deed of amendment (the “2020 Amendment”) was entered into in respect of the 2019 LCA. The 2020 Amendment had two main purposes (i) to grant additional options to acquire intellectual property rights for a third and fourth molecule; and (ii) to allow Ares to exercise its option early to acquire intellectual property rights to the second molecule included in the 2019 LCA as well as to terminate the R&D services. An option fee of $8.5 million was paid by Ares to the Company on exercise of the option to acquire rights to the second molecule.

During March 2021 Ares paid an option fee of $2.7 million to acquire the rights to the third molecule.

As a result of the 2020 Amendment, the maximum amount payable by Ares on the achievement of certain development and regulatory milestones in the aggregate was increased to $473.9 million, and the maximum amount payable on the achievement of certain commercial milestones was increased to $292.3 million. In addition, to the extent that any product candidates covered by the exclusive licenses granted to Ares are commercialized, the Company will be entitled to receive a single digit royalty based on a percentage of net sales on a country-by-country basis.

Revenue recognition

Management has considered the performance obligations identified in the Ares LCA and concluded that the option for the grant of intellectual property rights is not distinct from the provision of R&D services, as the R&D services would significantly modify the early-stage intellectual property. As a result, the option for the grant of intellectual property rights and the provision of R&D services has been combined into a single performance obligation for each individual molecule included in the 2019 LCA. The Company recognized revenue using the cost-to-cost method, which it believes best depicted the transfer of control of the services to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation.

The total transaction price for the 2019 LCA, was initially determined to be $15.4 million, consisting of the upfront payment for the first molecule and research and development funding for the research term for the second molecule. Variable consideration to be paid to the company upon reaching certain milestones had been excluded from the calculation, as at the inception of the contract, it was not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period.

There were two components identified in the 2020 Amendment, each of which was accounted for as a separate performance obligation. The first component, the grant of the additional options to acquire intellectual property rights for the third and fourth molecule, was deemed to be distinct, as the customer can benefit from it on its own, and it is independent of the delivery of other performance obligations in the 2019 LCA. Additionally, as the amount of consideration reflects a standalone selling price, the Company determined that the second component is accounted for as a separate contract.

The second component, which allowed the customer to exercise its option to acquire intellectual property rights to the second molecule early, is considered to be a modification of the 2019 LCA. This is because the option is not independent of the R&D services provided under the 2019 LCA, and therefore the goods and services are not distinct. The Company updated the transaction price and measure of progress for the performance obligation relating to this molecule.

For the three and nine months ended September 30, 2020, $0.2 million and $1.5 million was recognized in relation to the first antibody included in the 2020 Amendment.

During the nine months ended September 30, 2021, Ares provided notice of its intention to exercise its option granted under the 2020 Amendment to acquire the intellectual property rights for an additional molecule and $2.7 million was recognized at a point in time in respect of the option exercise.

License and collaboration agreement with Denali Therapeutics, Inc.

Summary

In August 2016 the Company entered into an exclusive license and collaboration agreement (the “Denali LCA”) with Denali. Under the terms of the Denali LCA, Denali was granted the right to nominate up to three Fcab targets for approval (“Accepted Fcab Targets”), within the first three years of the date of the agreement. Upon entering into the Denali LCA, Denali had selected Transferrin receptor as the first Accepted Fcab Target and paid an upfront fee of $5.5 million to the Company. In May 2018, Denali exercised its right to nominate two additional Fcab targets and identified a second Accepted Fcab Target. Denali made a one-time payment to the F-star group for the two additional Accepted Fcab Targets of $6.0 million and extended the time period for its selection of the third Accepted Fcab Target until August 2020.

Under the terms of the agreement the Company is entitled to receive contingent payments that relate to certain defined preclinical, clinical, regulatory, and commercial milestones with a maximum value of $49.5 million.

Revenue recognition

The initial transaction price for first Accepted Fcab Target was deemed to be $7.1 million consisting of $5.0 million for the grant of intellectual property rights and $2.1 million for R&D services. The initial transaction price for the second Accepted Fcab target was $5.1 million, consisting of $3.0 million for the grant of intellectual property rights and $2.1 million for R&D services. During the year ended December 31, 2019, the transaction price for the first Accepted Fcab was increased to $6.6 million due to achievement of a $1.5 million milestone that on initial recognition of the Denali LCA was not included in the transaction price, as it was not deemed probable that a reversal would not occur in a future reporting period.

All performance obligations were deemed to have been fully satisfied during the year ended December 31, 2019 in respect of the first Accepted Fcab Target, and during the three months ended March 30, 2021 in respect of the second Accepted Fcab Target. As a result, 0 revenue was recognized in respect of these targets for the three months ended September 30, 2021. In respect of the second Accepted Fcab Target, for the nine months ended September 30, 2021 and 2020, the Company recognized $0.1 million and $1.1 million, respectively, and for the three months ended September 30, 2020, the Company recognized $0.5 million.

2021 Agreement with AstraZeneca

Summary

On July 7, 2021 the Company entered into ~~the 2021 Sales~~a License Agreement with ~~SVB Leerink with respect to an~~

~~”at-the-market”~~

~~(“ATM”) offering program under which~~AstraZeneca AB. Under the terms of the agreement the Company ~~could offer~~has granted an exclusive license to certain patents and ~~sell,~~know-how to develop, manufacture and commercialize STING inhibitor compounds. AstraZeneca will be responsible for all future research, development and commercialization activities.

For the exclusive rights granted, an initial upfront fee of $0.5 million was paid by AstraZeneca to the Company during the three months ended September 2021. The Company is entitled to receive additional contingent near-term preclinical milestones of $11.5 million, plus maximum contingent payments that relate to certain defined development and regulatory milestones of $96.5 million and commercial milestones of $221.3 million, as well as royalty payments based upon a single digit percentage on net sales of products developed. Pursuant to the STING Antagonist CVR Agreement, 80% of net proceeds received the Company under the License Agreement with AstraZeneca will be payable, pursuant to the Exchange Agreement, to common stockholders of Spring Bank as of November 19, 2020, immediately prior to the Closing of the transaction.

Revenue recognition

Management has identified a single performance obligation in the contract, which is the grant of intellectual property rights.

The total transaction price was initially determined to be $0.5 million, consisting only of the upfront payment. Variable consideration to be paid to the company upon reaching certain milestones has been excluded from the calculation, as at the inception of the contract, it is not probable that a significant reversal of revenue recognized would not occur in a subsequent reporting period. The transaction price was allocated to the single performance obligation, which was deemed to be fully satisfied on the grant of intellectual property rights, and therefore the initial upfront fee was recognized at a point in time.

In the three and nine months ended September 30, 2021, the Company recorded revenue of $0.5 million in respect of this contract.

Summary of Contract Assets and Liabilities

Up-front payments and fees are recorded as deferred revenue upon receipt or when due until such time as the Company satisfies its performance obligations under these arrangements. A contract asset is a conditional right to ~~time at~~consideration in exchange for goods or services that the Company has transferred to a customer. Amounts are recorded as accounts receivable when the Company’s right to consideration is unconditional.

The following table presents changes in the balances of the Company’s contract liabilities (in thousands):

Contingent value rights

The acquisition-date fair value of the Contingent Value Rights ("CVR") liability represents the future payments that are contingent upon the achievement of sale or licensing for the STING product candidates. The fair value of the contingent value rights is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. The current liability of the CVR was $0.6 million and $2.1 million at September 30, 2021 ~~Sales Agreement.~~and December 31, 2020, respectively. The long term liability of the CVR was $2.9 million and $0.4 million at September 30, 2021 and December 31, 2020, respectively. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

Overview

F-star

Therapeutics, Inc.

(collectively with its subsidiaries,

~~“F-star”~~

“F-star” or the “Company”) is a clinical-stage biopharmaceutical company dedicated to developing next generation immunotherapies to transform the lives of patients with cancer.

F-star is pioneering the use of tetravalent (2+2) bispecific antibodies to create a paradigm shift in cancer therapy. The Company has four second generation immuno-oncology ("IO") therapeutics in the clinic, each directed against some of the most promising IO targets in drug development, including LAG-3 and CD137. F-star’s

proprietary antibody discovery platform is protected by an extensive IP estate. F-star has over 500 granted patents and pending patent applications relating to its platform technology and associated product pipeline. The Company has attracted multiple partnerships with biopharma targeting the significant unmet needs across several disease areas, including oncology, immunology, and CNS. F-star’s goal is to offer patients better and more durable benefits than currently available immuno-oncology treatments by developing medicines that seek to block tumor immune evasion. Through our proprietary tetravalent, bispecific natural antibody (mAb²

™

) format, our mission is to generate highly differentiated medicines with monoclonal antibody-like manufacturability, good safety and tolerability. With four distinct binding sites in a natural human antibody format, we believe that our proprietary technology will overcome many of the challenges facing current immuno-oncology therapies, due to the strong pharmacology enabled by tetravalent bispecific binding.

Our Programs

F-star’s

most advanced product candidate, FS118, is currently being evaluated in a

proof-of-concept

Phase 2 trial in

PD-1/PD-L1

acquired resistance head and neck cancer patients. FS118 is a tetravalent mAb

bispecific antibody targeting two receptors,

PD-L1

and

LAG-3,

both of which are ~~established pivotal~~validated targets in immuno-oncology. Phase 1 data from 43 heavily

pre-treated

patients with advanced cancer, who have failed

PD-1/PD-L1

therapy, showed that administration of FS118 was well-tolerated with no dose limiting toxicities up to 20 mg/kg. In addition, a disease control rate (“DCR”), defined as either a complete response, partial response or stable disease, of 49% was observed in 39 evaluable patients receiving dose levels of FS118 of 1mg/kg or greater. In acquired resistance patients, DCR was 59% (16 out of 27 patients) and long-term (greater than six months) disease control was observed in six of these patients. We expect to provide an update from the

proof-of-concept

Phase 2 trial in

PD-1/PD-L1

acquired resistance head and neck cancer patients in ~~H1 2022.~~

mid-2022. Recent data from an external randomized phase 3 trial in patients with previously untreated, locally advanced or metastatic melanoma provides clinical validation for the combination of LAG-3 and PD-1 inhibition. This clinical benefit in targeting PD-1 and LAG-3 gives us reason to believe that FS118 has potential to benefit patients not only with acquired resistance, but also in preventing resistance in patients receiving PD-1 monotherapy. We are initiating a clinical trial in checkpoint inhibitor (CPI) naïve patients in biomarker enriched non-small cell lung cancer (“NSCLC”) and diffuse large B cell lymphoma (“DLBCL”) populations in second half of 2021.

F-star’s

second product candidate, FS120, aims to improve checkpoint inhibitor and chemotherapy outcomes and is a ~~mAb2~~mAb2 bispecific antibody that is designed to bind to and stimulate OX40 and CD137, two proteins found on the surface of T cells that both function to enhance T cell activity.

F-star

is developing FS120 alone and in combination with

PD-1/PD-L1

therapy for the treatment of tumors where

PD-1/PD-L1

products are approved, and which have

co-expression

of OX40 and CD137 in the tumor microenvironment.

F-star

initiated a Phase 1 clinical trial in patients with advanced cancers in the fourth quarter of 2020 and ~~plan to provide an update on~~has completed the accelerated dose titration phase during the fourth quarter of ~~this study~~2021. We are continuing further dose escalation to determine an optimal dosing regimen to initiate a combination of FS120 and the PD-1 inhibitor, pembrolizumab, in

~~mid-2021.~~

2022. Pembrolizumab will be supplied under clinical trial collaboration and supply agreement with Merck & Co..

F-star’s

third product candidate, FS222, aims to improve outcomes particularly in low

PD-L1

expressing tumors and is a ~~mAb2~~mAb2 bispecific antibody that is designed to target both the costimulatory CD137 and the inhibitory

PD-L1

receptors, which are

co-expressed

in a number of tumor types.

F-star

initiated a Phase 1 clinical trial in patients with advanced cancers for FS222 in late 2020. We believe there is a strong rationale to combine FS222 with other anti-cancer agents, including targeted therapy and chemotherapy, and this can be done within the Phase 1 study. We expect to report an update on ~~this~~the current single agent dose escalation study in ~~late~~the fourth quarter of 2021.

SB 11285, which

F-star

acquired pursuant to a business combination with Spring Bank Pharmaceuticals, Inc. (“Spring Bank”), is a next generation cyclic dinucleotide STimulator of INterferon Gene (“STING”) agonist designed to improve checkpoint inhibition outcomes as an immunotherapeutic compound for the treatment of selected cancers.

~~F-star~~

~~is conducting an open-label, dose-escalation Phase 1 clinical trial with~~ SB 11285 ~~as an IV administered monotherapy,~~appeared to be well tolerated both alone and in combination with an

~~anti-PD-L1~~

Share Exchange Agreement

On November 20, 2020,

~~F-star~~

~~Therapeutics, Inc.,~~ the Company, formerly known as Spring Bank, ~~Pharmaceuticals, Inc.,~~ completed a business combination (the “Transaction”) with

F-star

Therapeutics Limited

(“F-star

Ltd”) in accordance with the terms of the Share Exchange Agreement, dated July 29, 2020 (the “Exchange Agreement”), by and among the Company,

F-star

Ltd and certain holders of the capital stock and convertible notes of

F-star

Ltd (each a “Seller”, and collectively with holders of

F-star

Ltd securities who subsequently became parties to the Exchange Agreement, the “Sellers”). Pursuant to the Exchange Agreement, each ordinary share of

F-star

Ltd outstanding immediately prior to the closing of the Transaction (the “Closing”) was exchanged by the Sellers that owned such

F-star

Ltd shares for a number of duly authorized, validly issued, fully paid and

non-assessable

shares of Company common stock pursuant to an exchange ratio formula as set forth in the Exchange Agreement (the “Exchange Ratio”), rounded to the nearest whole share of Company common stock (after aggregating all fractional shares of Company common stock issuable to such Seller). Also, on November 20, 2020, in connection with, and prior to completion of, the Transaction, Spring Bank effected a

1-for-4

reverse stock split of its common stock (the “Reverse Stock Split”) and, following the completion of the Transaction, changed its name to

F-star

Therapeutics, Inc. Following the completion of the Transaction, the business of the Company became the business conducted by

F-star,

Under the terms of the Exchange Agreement, at the Closing, Spring Bank issued an aggregate of 4,620,618 shares of its common stock to

F-star

Ltd stockholders, based on an Exchange Ratio of 0.1125 shares of Spring Bank common stock for each

F-star

Ltd pursuant to a formula set forth in the Exchange Agreement.

Pursuant to the Exchange Agreement, immediately prior to the Closing, certain investors in

F-star

Ltd purchased $15.0 million of

F-star

Ltd ordinary shares (the

~~“Pre-Closing~~

“Pre-Closing Financing”). These ordinary shares of

F-star

Ltd were then exchanged at the Closing for shares of the Company’s common stock in the Transaction at the Exchange Ratio.

Pursuant to the Exchange Agreement, all outstanding options to purchase Spring Bank common stock were accelerated immediately prior to the Closing and each outstanding option with an exercise price greater than the closing price of the stock on the Closing Date was exercised in full and all other outstanding options to purchase Company common stock were cancelled effective as of the Closing Date.

Immediately following the Reverse Stock Split and the Closing, there were approximately 4,449,559 shares of Spring Bank common stock outstanding. Following the Closing, the

F-star

Ltd stockholders beneficially owned approximately 53.7% of the combined company’s common stock, and the existing stockholders of Spring Bank beneficially owned approximately 46.3% of the combined company’s common stock. Concurrently with the execution of the Exchange Agreement, certain officers and directors of Spring Bank and

F-star

Ltd and certain

stockholders of

F-star

Ltd entered into

lock-up

agreements, pursuant to which they agreed to certain restrictions on transfers of any shares of the Company’s common stock for the

180-day

period following the Closing, other than the shares of the Company’s common stock received in exchange for ordinary shares of

F-star

Ltd subscribed for in the

Pre-Closing

Financing and pursuant to certain other limited exceptions.

In addition, at the Closing, Spring Bank,

F-star

pre-Reverse

Stock Split share of Spring Bank common stock held by stockholders as of the record date on November 19, 2020, immediately prior to the Closing, received a dividend of one contingent value right (“CVR”) (“STING Agonist CVR”), payable on a

pre-Reverse

Stock Split basis, entitling such holders to receive, in connection with certain transactions involving proprietary STING agonist compound designated as SB 11285 occurring on or prior to the STING Agonist CVR Expiration Date (as defined below) that resulted in aggregate Net Proceeds (as defined in the STING Agonist CVR Agreement) at least equal to the Target Payment Amount (as defined below), an aggregate amount equal to the greater of (i) 25% of the Net Proceeds received from all CVR Transactions (as defined in the STING Agonist CVR Agreement) and (ii) an aggregate amount equal to the product of $1.00 and the total number of shares of Company common stock outstanding as of such record date (not to exceed an aggregate amount of $18.0 million) (the “Target Payment Amount”).

The CVR payment obligation expires on the later of 18 months following the Closing or the

one-year

anniversary of the date of the final database lock of the STING clinical trial (as defined in the STING Agonist CVR Agreement) (the “STING Agonist CVR Expiration Date”). The STING Agonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest and are not registered with the SEC or listed for trading on any exchange. Until the STING Agonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) complete the STING Trial and (b) pursue a CVR Transaction. The STING Agonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Agonist CVR Expiration Date the payment or all CVR payment amounts are paid pursuant to their terms.

~~Table of Contents~~

At the Closing, Spring Bank,

F-star

Ltd, a representative of Spring Bank stockholders prior to the Closing, and Computershare Trust Company N.A., as the Rights Agent, also entered into a STING Antagonist Contingent Value Rights Agreement (the “STING Antagonist CVR Agreement”). Pursuant to the Exchange Agreement and the STING Antagonist CVR Agreement, each share of common stock held by Spring Bank stockholders as of November 19, 2020, immediately prior to the Closing, received a dividend of one CVR (“STING Antagonist CVR”) entitling such holders to receive, in connection with the execution of a potential development agreement (the “Approved Development Agreement”) and certain other transactions involving proprietary STING antagonist compound occurring on or prior to the STING Antagonist CVR Expiration Date (as defined below) equal to: 80% of all net proceeds (as defined in the STING Antagonist CVR Agreement) received by the Company after the Closing pursuant to (i) the Approved Development Agreement, if any, and (ii) all CVR Transactions (as defined in the STING Antagonist CVR Agreement) entered into prior to the STING Antagonist CVR Expiration Date.

~~The CVR payment obligations expire on the seventh anniversary of the Closing (the “STING Antagonist CVR Expiration Date”).~~

The STING Antagonist CVRs are not transferable, except in certain limited circumstances, are not certificated or evidenced by any instrument, do not accrue interest, and are not registered with the SEC or listed for trading on any exchange. Until the STING Antagonist CVR Expiration Date, subject to certain exceptions, the Company is required to use commercially reasonable efforts to (a) consummate the Approved Development Agreement, (b) to perform the terms of the Approved Development Agreement and (c) pursue CVR Transactions. The STING Antagonist CVR Agreement became effective upon the Closing and, unless terminated earlier in accordance with its terms, will continue in effect until the STING Antagonist CVR Expiration Date or all CVR payment amounts are paid pursuant to their terms.

On July 8, 2021, the Company entered into a License Agreement with AstraZeneca AB (“AstraZeneca”) under which AstraZeneca will receive global rights to research, develop and commercialize next generation STING inhibitor compounds. Under the terms of the agreement, AstraZeneca is granted exclusive access to and will be responsible for all future research, development and commercialization of the STING inhibitor compounds. F-star is eligible to receive upfront and near-term payments of up to $12 million upon meeting certain milestones. In addition, F-star will be eligible for development and sales milestone payments of over $300 million, as well as single digit percentage royalty payments. Payments received by F-star are subject to a contingent value

rights agreement (CVR 2), under which 80% will be payable to stockholders of F-star that were previously stockholders of Spring Bank prior to the business combination between F-star and Spring Bank.

The acquisition-date fair value of the CVR liability represents the future payments that are contingent upon the achievement of sale or licensing for the product candidates. The fair value of the contingent consideration acquired of $2.5 million as of December 31, 2020, and $3.5 million as of ~~March 31, 2021]~~September 30, 2021, is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

For the three months ended September 30, 2021, the estimated fair value increased to $3.5 million which resulted in a $0.4 million charge on the Consolidated Statements of Operations and Comprehensive Loss.

All issued and outstanding

F-star

Ltd share options granted under

F-star’s

three legacy equity incentive plans became exercisable in full immediately prior to the Closing. At the Closing, all issued share options and restricted stock units granted by

~~In connection~~$17.5 million with the entry into the Loan and Security Agreement, the Company issued to Horizon warrants (each, individually, a “Warrant” and, collectively, the “Warrants”) to purchase an aggregate number of shares of the Company’s common stock in an amount equal to $100,000 divided by the price for each respective Warrant. If at any time the Company files a registration statement relating to an offering for its own account, or the account of others, of any of its equity securities, the Company agreed to include such number of shares underlying the Warrants in that registration statement as requested by the holder.

offering, as defined in Rule 415 of the Securities Act of 1933, as amended, under which the Company could offer and sell, from time to time in its sole discretion, shares of its common stock, par value $0.0001 per share, having an aggregate offering pricetotal potential income of up to ~~$50.0 million (the “Placement Shares”) through SVB Leerink as its sales agent.~~

~~Upon delivery~~$1.35 billion. F-star is also eligible to receive potential tiered mid-single digit royalties on annual net sales.

Components of a placement notice in April 2021, and subject to the terms and conditions of the 2021 Sales Agreement, SVB Leerink began to sell the Placement Shares. The Company agreed to pay SVB Leerink a commission equal to three percent of the gross sales proceeds of any Placement Shares sold through SVB Leerink under the 2021 Sales Agreement, and also provided SVB Leerink with customary indemnification and contribution rights. As of May 6, 2021, the Company had issued and sold 979,843 shares, for gross proceeds of $9.5 million, resulting in net proceeds of $9.2 million after deducting sales commissions. On May 6, 2021, the Company terminated the 2021 Sales Agreement.

On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the underwriters, relating to an underwritten public offering of approximately 9.3 million shares of the Company’s common stock, par value $0.0001 per share. The underwritten public offering resulted in gross proceeds of $65.0 million. The Company incurred $3.9 million in issuance costs associated with the underwritten public offering, resulting in net proceeds to the Company of $61.1 million.

~~Financial Operations Overview~~

Operating Results

License revenue

To date, we have not generated any revenue from product sales, and we do not expect to generate any revenue from product sales for the foreseeable future. Our revenue consists of collaboration revenue under our license and collaboration agreements with Ares Trading S.A. (“Ares”) ~~and~~, Denali Therapeutics, Inc. (“Denali”), and AstraZeneca, including amounts that are recognized related to upfront payments, milestone payments, option exercise payments, and amounts due to us for research and development services. In the future, revenue may include new collaboration agreements, additional milestone payments, option exercise payments, and royalties on any net product sales under our collaborations. We expect that any revenue we generate will fluctuate from period to period as a result of the timing and amount of license, research and development services, and milestone and other payments.

Operating Expenses

Research and development costs

milestone payments made for the licensing of technology are expensed as research and development in the period in which they are incurred, except for payments relating for intellectual property rights with future alternative use which will be expensed when the intellectual property is in use.

Non-refundable

advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. The prepaid amounts are expensed as the related goods are delivered or the services are performed.

Those expenses associated with R&D and clinical costs primarily include:



expenses incurred under agreements with contract research organizations (“CROs”) as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;



manufacturing

scale-up

expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials;



expenses incurred for outsourced professional scientific development services;



costs for laboratory materials and supplies used to support our research activities;



allocated facilities costs, depreciation, and other expenses, which include rent and utilities;



up-front,

milestone and management fees for maintaining licenses under our third-party licensing agreements; and



compensation expense.

~~Table of Contents~~

The Company recognizes external R&D costs based on an evaluation of the progress to completion of specific tasks using information provided to it by its internal program managers and service providers.

Research and development activities are central to the Company’s business models. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials. As a result, the Company expects that research and development expenses will increase over the next several years as the Company increases personnel costs, initiate and conduct additional clinical trials and prepare regulatory filings related to the various product candidates.

The successful development of our product candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the remainder of the development of these product candidates. We are also unable to predict when, if ever, material net cash inflows will commence from our product candidates. This is due to the numerous risks and uncertainties associated with developing products, including the uncertainty of:



~~completing~~ research and ~~preclinical~~ development support of our product candidates, including conducting future clinical trials of FS118, FS120, FS222 and SB 11285;



progressing the ~~preclinical and~~ clinical development of FS118, FS120, FS222 and ~~SB 11285;~~

SB11285;



establishing an appropriate safety profile with investigational new drug-enabling studies to advance our ~~preclinical~~ programs into clinical development;



identifying new product candidates to add to our development pipeline;



successful ~~enrolment~~enrollment in, and the initiation and completion of clinical trials;



the timing, receipt and terms of any marketing approvals from applicable regulatory authorities;



commercializing the product candidates, if and when approved, whether alone or in collaboration with others;



establishing commercial manufacturing capabilities or making arrangements with third party manufacturers;



the development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials;



addressing any competing technological and market developments, as well as any changes in governmental regulations;



negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter and performing our obligations under such arrangements;



maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and

know-how,

as well as obtaining and maintaining regulatory exclusivity for our product candidates;



continued acceptable safety profile of the drugs following approval; and



attracting, hiring, and retaining appropriately qualified personnel.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, the U.S. Food and Drug Administration, European Medicines Agency or another regulatory authority may require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or we may experience significant trial delays due to patient enrolment or other reasons, in which case we would be required to expend significant additional financial resources and time on the completion of clinical development. In addition, we may obtain unexpected results from our clinical trials, and we may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and

uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success.

General and administrative expenses

General and administrative expenses consist primarily of salaries, related benefits, travel, and share-based compensation expense for personnel in executive, finance, legal and administrative functions. General and administrative expenses also include facility-related costs, patent filing and prosecution costs, insurance and marketing costs and professional fees for legal, consulting, accounting, audit, tax services and costs associated with being a public company. Other expense also includes foreign currency transaction losses. The Company expects that general and administrative expenses will increase in the future as the Company expands its operating activities and incurs costs of being a US public company.

~~Table of Contents~~

Other income and expenses, net

Other income and expenses, net, is primarily rent received from subletting an office in the United States and interest received on overdue trade receivable balances, bank interest received, and interest expense, which is primarily bank interest payable and similar charges, the interest liability on leased assets and convertible debt notes, changes in the fair value of CVR and foreign exchange losses incurred. Foreign exchange gain (loss) is foreign exchange gains or losses due to the fluctuation of the GBP, U.S. dollar and/or the Euro. Change in the fair value of convertible debt is the fair value adjustment of the convertible notes as measured using level 3 inputs which was converted on November 20, 2020, with the transaction with Spring Bank.

~~Biotechnologische~~

~~Forschungs-und~~

~~Entwicklungsges.m.b.H~~ Our Austrian subsidiary has historical losses in Austria with more recent profits, which has resulted in payment of Austrian corporation tax in the years ended December 31, 2020, and 2019. The corporation tax benefit (tax) presented in the Company’s statements of comprehensive income (loss) represents the tax impact from its operating activities in the United States, United Kingdom and Austria, which have generated taxable income in certain periods. As the entities located in the United Kingdom carry out extensive research and development activities, they seek to benefit from the ~~U.K.~~UK research and development tax credit cash rebate regime known as the Small and

Medium-sized

Enterprises R&D Tax Credit Program (the “SME Program”). Qualifying expenditures largely comprise employment costs for research staff, consumables expenses incurred under agreements with third parties that conduct research and development, preclinical activities, clinical activities and manufacturing on the Company’s behalf and certain internal overhead costs incurred as part of research projects. ~~No research and development activities are carried out in Austria, so the Company is not able to utilize the research and development premium available under the Austrian corporation tax regime.~~

The tax credit received in the United Kingdom pursuant to the SME Program permits companies to deduct an extra 130% of their qualifying costs from their yearly profit or loss, as well as the normal 100% deduction, to make a total 230% deduction. If the company is incurring losses, it is entitled to claim a tax credit worth up to 14.5% of the surrenderable loss. To qualify for relief under the SME Program, companies are required to employ fewer than 500 staff and have a turnover of under €100.0 million or a balance sheet total of less than €86.0 million.

~~The U.K. government has released draft legislation to introduce a cap on the amount of the payable credit that a qualifying loss-making small and~~

~~medium-sized~~

enterprise business can receive through research and development relief in any one year. The cap would be applied to restrict payable credit claims in excess of £20,000 with effect for accounting periods beginning on or after April 2021 by reference to, broadly, three times the total employee payroll tax and social security liabilities of the company. The draft legislation also contains an exemption which prevents the cap from applying. That exemption requires the company to be creating, or taking steps to create, intellectual property as well as having research and development expenditure in respect of connected parties which does not exceed 15% of the total claimed. The Company does not expect this legislation, if adopted, to have a material impact on its payable credit claims based on amounts currently claimed.

Research and development tax credits received in the United Kingdom are recorded as a reduction in research and development expenses. The ~~U.K.~~UK research and development tax credit is payable to companies after surrendering tax losses and is not dependent on current or future taxable income. As a result, it is not reflected as part of the income tax provision. ~~If, in~~

During the ~~future, any U.K.~~nine months ended September 30, 2021 the Company received $3.4 million in research and development tax credits ~~generated are utilized~~related to ~~offset a corporate income tax liability in~~ the United Kingdom, that portion would be recorded as a benefit within the income tax provision, and any refundable portion not dependent on taxable income would continue to be recorded as a reduction to research and development expenses.

year ended December 31, 2020.

Income tax expense was ~~relatively flat compared to~~not material for the three and nine months ended ~~March 31, 2020.~~

In the event the Company generates revenues in the future, the Company may benefit from the United Kingdom “patent box” regime that allows profits attributable to revenues from patents or patented products to be taxed at an effective rate of 10%. Value Added Tax (“VAT”) is broadly charged on all taxable supplies of goods and services by

~~VAT-registered~~

businesses. In the United Kingdom, under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to the United Kingdom’s tax authority, Her Majesty’s Revenue and Customs (“HMRC”). Similarly, VAT paid on purchase invoices is generally reclaimable from HMRC. In Austria, under current rates, an amount of 20% of the value, as determined for VAT purposes, of the goods or services supplied is added to all sales invoices and is payable to the Austrian tax authority. Similarly, VAT paid on purchase invoices is generally reclaimable from the Austrian tax authority.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a predetermined schedule or when contractual milestones are met; however, some require advanced payments. We make estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:



CROs in connection with performing research services on our behalf and clinical trials;



investigative sites or other providers in connection with clinical trials;



vendors in connection with preclinical and clinical development activities; and



vendors related to product manufacturing, development and distribution of preclinical and clinical ~~supplies.~~supplies and material.

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.

Contingent value rights

The acquisition-date fair value of the CVR liability represents the future payments that are contingent upon the achievement of sale or licensing for the STING product candidates. The fair value of the contingent value rights is based on the Company’s probability-weighted discounted cash flow assessment that considers probability and timing of future payments. The fair value measurement is based on significant Level 3 unobservable inputs such as the probability of achieving a sale or licensing agreement, anticipated timelines, and discount rate. Changes in the fair value of the liability will be recognized in the consolidated statement of operations and comprehensive loss until settlement.

Share-based compensation

The Company accounts for share-based compensation in accordance with ASC 718, “Compensation – Stock Compensation” (“ASC 718”). ASC 718 requires companies to estimate the fair value of equity-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service period in the Company’s consolidated statements of operations and comprehensive loss.

The Company records the expense for option awards using a graded vesting method. The Company accounts for forfeitures as they occur. For share-based awards granted to

non-employee

consultants, the measurement date is the date of grant. The compensation expense is then recognized over the requisite service period, which is the vesting period of the respective award.

The fair value of stock options (“options”) on the grant date is ~~estimated using~~determined utilizing the Black-Scholes option-pricing model using the single-option approach. The Black-Scholes option pricing model requires the use of highly subjective and complex assumptions, including an option’s expected term and the price volatility of the underlying stock, to determine the fair value of the award.

~~Historically given the absence of an active market for the ordinary shares of~~

~~F-star~~

Ltd, the board of directors determined the estimated fair value of the Company’s equity instruments based on input from management, which utilized the most recently available independent third-party valuation, and considering a number of objective and subjective factors, including external market conditions affecting the biotechnology industry sector. Each valuation methodology includes estimates and assumptions that require judgment. These estimates and assumptions include a number of objective and subjective factors in determining the value of

~~F-star~~

Ltd ordinary shares at each grant date. The expected volatility for F star Ltd was calculated based on reported volatility data for a representative group of publicly traded companies for which historical information was available. The historical volatility is calculated based on a period of time commensurate with the assumption used for the expected term. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant commensurate with the expected term assumption.

~~F-star~~

~~Ltd used the simplified method, under which the expected term is presumed to be the midpoint between the vesting date and the end of the contractual term.~~

~~F-star~~

~~Ltd utilized this method due to the lack of historical exercise data and the plain nature of its share-based awards.~~

~~Table of Contents~~

~~The Company uses the remaining contractual term for the expected life of~~

~~non-employee~~

~~awards. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends.~~

The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss Income in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

~~Revenue from contracts with Ares~~development costs

Total Research and development expenses were $5.1 million for the three months ended ~~March 31,~~September 30, 2021, ~~increased by $1.9~~as compared to $5.3 million ~~from~~for the prior year's third quarter. This $0.2 million decrease for the three months ended ~~March 31, 2020~~September 30, 2021, was due to an increase in clinical CRO costs of $1.6 million, due to a full quarter of Phase 1

clinical trial costs for FS120 and FS222 and SB11285 in 2021, a $0.9 million increase in R&D staff related costs, and $0.3 million in lab consumables, all offset by a $2.3 million reduction in the UK R&D tax credit, and decreases in manufacturing costs of $0.4 million and other allocated costs of $0.3 million.

General and administrative expense

General and administrative expense for the three months ended September 30, 2021, decreased by approximately $2.0 million over the prior comparable quarter, primarily due to a decrease in legal and professional costs of $2.6 million, due to costs incurred in the comparative period in preparation for the share exchange transaction with Spring Bank, and a decrease in staff costs of $0.6 million, offset by increases in insurance costs of $0.5 million, rent and repairs of $0.5 million, primarily due to the ~~payment~~leased buildings acquired in the Spring Bank transaction, and other administrative costs of ~~an option fee~~$0.2 million.

Other income (expenses)

Other income (expense) for the three months ended September 30, 2021, consisted primarily of ~~$2.7~~rental income of $0.2 million ~~to acquire intellectual property rights, which was~~ offset by ~~a reduction in R&D service revenues~~foreign exchange losses of ~~$0.8~~$0.6 million and interest expense on the term debt of $0.3 million. In addition, there was a ~~decrease~~loss of $0.4 million for the change in ~~overall revenue~~fair value of the CVR liability.

For the three months ended September 30, 2020, the total expense of $0.5 million consisted of other income of $0.8 million of foreign currency gains offset by $0.3 million of interest related to the convertible notes.

A gain of $0.4 million was recorded in relation to a fair value adjustment for the convertible notes.

Licensing and Research & Development Services Revenue

Revenue for the nine months ended September 30, 2021, was $3.7 million compared with $11.1 million for the nine months ended September 30, 2020, a decrease of $7.4 million.

Revenue from contracts with Ares decreased by $7.1 million due to a reduction in licensing revenue and R&D services revenue.

In addition, there was a $1.0 million decrease relating to licensing and R&D services ~~for the second molecule in the Company’s License and Collaboration Agreement~~revenue with Denali. All performance obligations relating to this ~~molecule~~Denali contract were satisfied in February 2021.

These were offset by $0.5 million in revenue related to the license agreement with AstraZeneca executed in July 2021 ~~which resulted~~and $0.2 million in ~~portion of revenue recognized during the three months ended March 31, 2021.~~

General and administrative expense for the ~~three~~nine months ended ~~March 31,~~September 30, 2021 ~~increased by approximately $3.2~~was $18.2 million, ~~as compared to the three months ended March 31, 2020, to $6.4 million due to~~ an increase of ~~$1.4~~approximately $4.4 million, compared to $13.8 million for the nine months ended September 30, 2020.This increase was primarily due to $2.5 million in share-based compensation expense, $1.5 million in ~~professional fees,~~ insurance and other costs ~~associated with~~of being a public company, $0.4 million in legal and professional fees, $0.3 million in ~~other~~IT costs and $0.6 million in rent and repairs, primarily ~~due~~related to ~~additional rent for~~ the leased buildings acquired ~~with~~in the Spring Bank transaction.

These increases were offset by a decrease in staff costs of $0.9 million.

In addition, there was ~~a charge~~an expense of ~~$0.4~~$1.0 million for the change in fair value of the CVR.

For the nine months ended September 30, 2020, other expense of $1.2 million consisted of foreign currency losses of $0.9 million, interest expense of $0.8 million in relation to the convertible debt, offset by other income of $0.5 million from the UK government Coronavirus Job Retention Scheme, for staff that were furloughed in the ~~for three months ended March 31,~~first half of 2020.

In addition, a fair value adjustment in respect of the convertible debt of $2.3 million was recorded.

Liquidity and Capital Resources

Sources of liquidity

From our inception through ~~March 31,~~September 30, 2021, we have not generated any revenue from product sales, and we have incurred significant operating losses and negative cash flows from our operations. We do not expect to generate significant revenue from sales of any products for several years, if at all.

As of ~~March 31,~~September 30, 2021, the Company had an accumulated deficit of ~~$57.0~~$83.2 million, cash of ~~$3.7~~$71.1 million and ~~accounts payable and accrued expenses~~working capital of ~~$11.1~~$67.3 million. The future success of the Company is dependent on its ability to successfully obtain additional working capital, obtain regulatory approval for and successfully launch and commercialize its product candidates and to ultimately attain profitable operations.

As of November 10, 2021 the Company’s cash and

cash equivalents on hand will be sufficient to fund its current operating plan and planned capital expenditures for at least the next 12 months.

Historically, we have financed our operations ~~primarily~~ with proceeds from the sale and issuance of equity securities, proceeds from the issuance of ~~ordinary~~notes payable and ~~convertible preferred shares, proceeds from issuances in connection with a convertible note facility,~~ proceeds received ~~from upfront payments and development milestone payments~~ in connection with our collaboration arrangements and ~~payments received~~ for providing research and development services. We expect this historical financing trend to continue if and until we are able obtain regulatory approval for and successfully commercialize one or more of our drug candidates, although there can be no assurance that we will obtain regulatory approval or successfully commercialize any of our current or planned future product candidates.

On March 30, 2021, the Company entered into a ~~2021~~ Sales Agreement with SVB Leerink LLC ("SVB Leerink") with respect to an

at-the-market

offering program under which the Company could offer and sell, from time to time in its sole discretion, shares of its common stock, par value $0.0001 per share, having an aggregate offering price of up to $50.0 million through SVB Leerink as its sales agent. As of May 6, 2021, the Company had issued and sold 979,843 shares, for gross proceeds of $9.5 million, resulting in ~~net~~net proceeds of $9.2 million after deducting sales commissions. On May 6, 2021, the Company terminated the Sales Agreement.

On August 13, 2021, the Company entered into a new Sales Agreement (the “2021 Sales Agreement”) with SVB Leerink with respect to an at-the-market offering program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock having an aggregate offering price of up to $50.0 million through SVB Leerink as its sales agent. As of September 30, 2021 Company had not offered or sold any common stock under the 2021 Sales Agreement.

On May 6, 2021, the Company entered into an underwriting agreement with SVB Leerink, as representative of the underwriters, relating to an underwritten public offering of ~~approximately 9.3~~10.4 million shares of the Company’s common stock, par value $0.0001 per share. The underwritten public offering resulted in gross proceeds of ~~$65.0~~$73.1 million. The Company incurred ~~$3.9~~$4.4 million in issuance costs and $0.5 million of professional fees associated with the underwritten public offering, resulting in net proceeds to the Company of ~~$61.1~~$68.2 million.

On April 1, 2021, the Company, as borrower, entered into the Loan and Security Agreement with Horizon, ~~Technology Finance Corporation,~~ as lender and collateral agent for itself. The Loan and Security Agreement provides for four (4) separate and independent $2.5 million term loans ~~(“Loan A”, “Loan B”, “Loan C”, and “Loan D”) (with each of Loan~~(Loan A, Loan B, Loan C, and Loan ~~D, individually a “Term Loan” and, collectively, the “Term Loans”)~~D), whereby, upon the satisfaction of all the conditions to the funding of the Term Loans, each Term Loan ~~would~~will be delivered by Horizon to the Company in the following manner: (i) Loan A was ~~to be~~ delivered by Horizon to the Company ~~prior to~~by April 1, 2021, (ii) Loan B was ~~required to be~~ delivered by Horizon to the Company ~~prior to~~by April 1, 2021, (iii) Loan C ~~is required to be~~was delivered by Horizon to the Company ~~prior to~~by June 30, 2021, and (iv) Loan D ~~is required to be~~was delivered by Horizon to the Company ~~prior to~~by June 30, 2021.

Operating activities

Net cash used of ~~$14.4~~$34.0 million in operating activities for the ~~three~~nine months ended ~~March 31,~~September 30, 2021, consisted of the net loss of ~~$9.9~~$36.0 million adjusted for changes in operating assets and liabilities of ~~$6.2~~$5.1 million and offset by

non-cash

charges of ~~$1.7~~$7.1 million, primarily for share-based compensation expense of ~~$2.2~~$5.6 million, fair value adjustment of the CVR liability of $1.0 million, depreciation and amortization of $0.5 million, non-cash interest expense of $0.1 million, ~~depreciation of $0.1 million, and the deduction of~~offset by foreign exchange gains of ~~$0.7~~$0.1 million.

~~Financing activities~~

~~For the three months ended March 31,~~September 30, 2021, net cash provided by financing activities was ~~$0.~~ $87.0 million. This included $77.3 million raised on the issue of common stock, with $9.1 million of the total generated from the “at the market” offering and $68.2 million generated from the underwritten public offering, offset by $0.5 million legal fees in connection with the offering. In addition, we received net proceeds of $9.8 million from the Loan and Security Agreement with Horizon and third-party debt issuance costs of $0.1 million were paid.

Future Funding Requirements

The Company has incurred significant losses and has an accumulated deficit of ~~$57.0~~$83.2 million as of ~~March 31,~~September 30, 2021.

F-star

expects to incur substantial losses in the foreseeable future as it conducts and expands its clinical trial and research and development ~~and clinical trial activities.~~activities. As of ~~May 17,~~November 10, 2021 the ~~date of issuance of the consolidated financial statements, after proceeds from Sales Agreement~~Company’s cash and ~~drawdown of the Term Loans, the Company’s~~ cash ~~of approximately $76.3 million~~equivalents on hand will be sufficient to fund its current operating plan and planned capital expenditures for at least the next 12 months.

The Company may continue to seek additional ~~funding~~working capital through ~~public~~the sale and issuance of equity ~~private equity,~~securities, debt financing, collaboration ~~partnerships,~~arrangements or other sources. There are no assurances, however, that the Company will be successful in raising additional working capital, or if it is able to raise additional working capital, it may be unable to do so on commercially favorable terms. The Company’s failure to raise additional capital or enter into other ~~such~~financing arrangements if and when needed would have ~~a negative~~an adverse impact on its business, results of operations and financial condition and its ability to develop its product ~~candidates~~

candidates.

Our future capital requirements will depend on many factors, including:



our ability to raise capital in light of the impacts of the ongoing global

COVID-19

pandemic on the global financial markets;



the scope, progress, results, and costs of drug discovery, preclinical development, laboratory testing, drug manufacturing and clinical trials for the product candidates we have developed or may develop;



our ability to enroll clinical trials in a timely manner and to quickly resolve any delays or clinical holds that may be imposed on our development programs, particularly in light of the global

COVID-19

pandemic;



the costs associated with our manufacturing process development and evaluation of third-party manufacturers and suppliers;



the costs, timing and outcome of regulatory review of our product candidates;



the costs of preparing and submitting marketing approvals for any of our product candidates that successfully complete clinical trials, and the costs of maintaining marketing authorization and related regulatory compliance for any products for which we obtain marketing approval;



the costs of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property and proprietary rights, and defending intellectual property-related claims;

~~Table of Contents~~



the costs of future activities, including product sales, medical affairs, marketing, manufacturing, and distribution, for any product candidates for which we receive marketing approval;



the terms of our current and any future license agreements and collaborations; and the extent to which we acquire or

in-license

other product candidates, technologies and intellectual property;



the success of our collaborations with Janssen, AZ, Ares and Denali and other partners;



our ability to establish and maintain additional collaborations on favorable terms, if at all; and



the costs of operating as a public company.

Critical Accounting Policies and Significant Judgments and Estimates

Our condensed consolidated financial statements are prepared in accordance with ~~United States generally accepted accounting principles.~~U.S. GAAP and the rules and regulations of the SEC for interim financial statements. The preparation of our condensed consolidated financial statements and related disclosures requires our management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses and related disclosures. We believe that the estimates and assumptions underlying the accounting policies described therein may have the greatest potential impact on our consolidated financial statements and, therefore, consider these to be our critical accounting policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these current estimates based on different assumptions and under different conditions. There have been no material changes to the Company’s critical accounting policies and estimates as ~~discussed~~disclosed in the Company’s Annual Report filed on SEC Form

10-K

for the year ended December 31, 2020, filed with the SEC on March 30, 2021.

Contractual Obligations and Commitments

We enter into contracts in the normal course of business with third-party service providers for clinical trials, preclinical research studies and testing, manufacturing and other services and products for operating purposes. We have not included our payment obligations under these contracts ~~in the table~~ as these contracts generally provide for termination upon notice, and therefore, we believe that our

non-cancelable

obligations under these agreements are not material, and we cannot reasonably estimate the timing of if and when they will occur. We could also enter into additional research, manufacturing, supplier and other agreements in the future, which may require

up-front

payments and even long-term commitments of cash.

Off-Balance

Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any

off-balance

sheet arrangements, as defined in the rules and regulations of the SEC.

Emerging Growth Company and Smaller Reporting Company Status

We are an emerging growth company, (“EGC”) as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). We will remain an EGC until the earlier of (1) the last day of the fiscal year following the fifth anniversary of the completion of our initial public offering (December 31, 2021), (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion, (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule

12b-2

under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our ordinary shares held by

non-affiliates

exceeded $700.0 million as of the last business day of the second fiscal quarter of such fiscal year or (4) the date on

which we have issued more than $1.0 billion in

non-convertible

debt securities during the prior three-year period. The JOBS Act permits an EGC to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have irrevocably elected to “opt out” of this provision and, as a result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. In addition, we intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, we are entitled to rely on certain exemptions as an EGC we are not required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b), (ii) provide all of the compensation disclosure that may be required of

non-emerging

growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that has or may be adopted by the Public Company

~~Table of Contents~~

Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the chief executive officer’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of Spring Bank’s initial public ~~offering~~offering (December 31, 2021) or ~~until~~until we no longer meet the requirements of being an EGC, whichever is earlier.

We are also a smaller reporting company as defined under the Exchange Act. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) our voting and

non-voting

common stock held by

non-affiliates

is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and

non-voting

common stock held by

non-affiliates

is less than $700.0 million measured on the last business day of our second fiscal quarter.

Evaluation of Disclosure Controls and Procedures

As of ~~March 31,~~September 30, 2021, our management, under the supervision of our Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and procedures as defined in Rules

13a-15(e)

and

15d-15(e)

under the Exchange Act to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer ~~due~~determined the material weaknesses in our internal controls as previously disclosed in our Annual Report on Form ~~10-k~~10-K for the year ended December 31, ~~20220,~~2020, as described below, our disclosure controls and procedures were not effective as of ~~March 31,~~September 30, 2021.

Management’s Annual Report on Internal Control over Financial Reporting

We have performed an evaluation of the effectiveness of our internal control over financial reporting, based on criteria established by the Committee of Sponsoring Organizations of the Treadway Commission in its 2013 Internal Control-Integrated Framework. Based on that evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our internal control over financial reporting was not effective as of ~~March 31,~~September 30, 2021, due to material weaknesses in internal control over financial reporting, associated with (i) the lack of formal policies and procedures and sufficient complement of personnel to implement effective segregation of duties and (ii) the lack of sufficient formality and evidence of controls over key reports, contracts and spreadsheets.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future years 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.

As an EGC under the JOBS Act, we are exempt from the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002.

Remediation Plans

As discussed above, the material weaknesses over effective controls on the financial statement close and reporting process as well as lack of an effective control environment with formal processes and procedures and not having sufficient formality and evidence of controls as of December 31, 2020, were not fully remediated as of ~~March 31,~~September 30, 2021. We have commenced measures to remediate these material weaknesses and have hired additional finance and accounting personnel ~~during the fourth quarter of 2020~~ with appropriate expertise to perform specific functions which we believe will allow for proper segregation of duties, design key controls and implement improved processes and internal controls. We will continue to assess our finance and accounting staffing needs to ensure remediation of these material weaknesses. The material weaknesses will not be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control over Financial Reporting

There were 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 three months ended ~~March 31,~~September 30, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Intellectual property rights of third parties could adversely affect our ability to commercialize our product candidates, such that we could be required to litigate or obtain licenses from third parties in order to develop or market our product candidates. Such litigation is costly and any required licenses may not be available on commercially reasonable terms.

Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts. Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. However, our research, development and commercialization activities may be subject to claims that we infringe or otherwise violate patents or other intellectual property rights owned or controlled by third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, derivation proceedings, oppositions and inter partes reexamination proceedings before the USPTO, and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are pursuing development candidates.

In particular, we are aware of a “method of use” patent issued in 2021 in the United States to E.R. Squibb & Sons, L.L.C. that expires in 2029, subject to the timely payment of maintenance fees and absent any patent term extension, and which includes claims directed to a method for treating cancer in a subject comprising administering to the subject an anti-LAG-3 antibody and an anti-PD-L1 antibody, which antibodies are specified in a subclaim as being in a bispecific molecule. We believe, based on our review of this U.S. patent, that the patent claims are impermissibly broad and that there would be strong arguments available to us should we decide to challenge its validity in court or USPTO post-grant proceedings, based on prior art and lack of written description and enablement for the entire scope of the claims. If we succeed in developing and obtaining regulatory approval to market our product candidate FS118 in the future, this patent, prior to its expiration, could impact our commercial plans for FS118 in the United States. We do not expect the patent to have any impact on commercialization of FS118 outside of the United States, and we do not expect the patent to impact our pre-commercial development of FS118 inside or outside of the United States. We are also aware of a “second medical use” patent issued in 2021 in Europe to Bristol-Myers Squibb Company, which includes claims protecting until 2036 (subject to the timely payment of annual renewal fees and absent any supplementary protection certificates based on the patent) an anti-PD-1 or anti-PD-L1 antibody that inhibits PD-1 activity for use in a method for treating a subject identified as HPV positive and afflicted with a tumor derived from a HPV positive squamous cell carcinoma head and neck cancer, the method comprising administering to the subject a therapeutically effective amount of the antibody. Multiple parties, including Regeneron Pharmaceuticals, Inc. and Merck Sharp and Dohme Corp, have filed oppositions at the European Patent Office challenging the validity of this European patent. We believe, based on our review of this European patent and the oppositions that have been filed, that there are strong grounds to argue that the patent is invalid due to lack of novelty and inventive step based on prior art as well as impermissible added matter and lack of sufficiency. If not revoked or amended to a form that poses no or a sufficiently reduced risk to our business, this patent, prior to its expiration, could impact our commercial plans for FS118 and FS222 in Europe, but we do not

expect the patent to impact our pre-commercial development efforts. Patent litigation is costly and time-consuming and there is no assurance that we would prevail, should we initiate or defend such litigation. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that we may be subject to claims of infringement of the patent rights of third parties.

Our competitive position may suffer if patents issued to third parties or other third-party intellectual property rights cover our products or product candidates or elements thereof, our manufacture or uses relevant to our development plans, the targets of our mAb2 product candidates, or other attributes of our mAb2 product candidates or our mAb2 technology. In such cases, we may not be in a position to develop or commercialize products or product candidates unless we successfully pursue litigation to nullify or invalidate the third-party intellectual property right concerned or enter into a license agreement with the intellectual property right holder, if available on commercially reasonable terms or at all.

It is also possible that we fail to identify relevant patents or patent applications. For example, certain U.S. applications filed after November 29, 2000 that will not be filed outside the United States may remain confidential until issuance of a patent. In general, patent applications in the United States and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications relating to our products or platform technology could have been filed by others without our knowledge. Furthermore, we operate in a highly competitive field, and given our limited resources, it is unreasonable to monitor all patent applications purporting to gain broad coverage in the areas in which we are active. Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our platform technologies, our products or the use of our products.

Parties making claims of infringement against us or defending against our invalidity actions may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. If we fail in any such dispute, in addition to being forced to pay damages, we or our licensees may be temporarily or permanently prohibited from commercializing any of our product candidates that are held to be infringing. We might, if possible, also be forced to redesign product candidates so that we no longer infringe the third-party intellectual property rights. We may be required to seek a license to any such technology that we are found to infringe, which license may not be available on commercially reasonable terms, or at all. Even if we or our collaboration partners obtain a license, it may be non-exclusive; thereby giving our competitors access to the same technologies licensed to us or our licensors or collaboration partners. Moreover, such a license may require us to pay royalties to the licensor; thus, reducing our expected revenues. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent in the United States. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, they could have a substantial adverse effect on our share price. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. 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.

In addition, if the breadth or strength of protection provided by our or our collaboration partners’ patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.
