Note 1. Description of Business, Basis of Presentation and Principles of Consolidation

HTG Molecular Diagnostics, Inc. (the “Company”) is a ~~provider of instruments, reagents and services for molecular~~life science company whose mission is to advance precision medicine through its innovative transcriptome-wide profiling ~~applications.~~technology. The Company derives revenue from sales of its HTG EdgeSeq instrument system and integrated next-generation sequencing-based (“NGS-based”) HTG EdgeSeq assays, from ~~services including~~ sample processing and custom research use only (“RUO”) assay design services and from collaborative development services.

The Company operates in ~~one~~1 segment and its customers are located primarily in the United States and Europe. For the three and nine months ended September 30, ~~2020 19%~~2021 approximately 24% and ~~31%,~~30% respectively, of the Company’s revenue was generated from sales originated by customers located outside of the United States, compared with ~~29%~~19% and 31% for the three and nine months ended September 30, ~~2019,~~2020, respectively.

On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus (“COVID-19”) originating in Wuhan, China and the risks to the international community as the virus spreads globally. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic.

The full impact of the COVID-19 pandemic (“COVID-19”) continues to evolve as of the date of this report and ~~likewise the full impact of the pandemic on the Company’s financial condition, liquidity and future results of operations is uncertain. Management is~~management continues to actively ~~monitoring~~monitor the potential impact of the global situation on its financial condition, liquidity and future results of operations, suppliers, industry and workforce. Given the ~~daily~~ongoing evolution of COVID-19, including the ~~COVID-19 pandemic~~emergence of variants and resurgences in many areas of the world and the global responses to curb its spread, the Company is not able to fully estimate the effects of ~~the~~ COVID-19 ~~pandemic~~ on its results of operations, financial condition or liquidity.

The Company experienced a significant slowing of product and product-related services revenue generation beginning in March 2020 and ~~believes this period~~continuing throughout 2020 and the three quarters of ~~reduced revenue will continue through at least the remainder of 2020 due to disruptions to its customers’ businesses as a result of the pandemic.~~2021. The extent of this impact has varied from customer to customer depending upon how they have been directly or indirectly impacted by local stay-at-home orders and other social distancing measures, prioritization by those customers as the immediate impacts of the pandemic have passed, and the workforce and supplier impacts that COVID-19 has had on each customer has experienced during the pandemic. The Company has experienced very limited delays in its development efforts as a result of stay-at-home orders despite its efforts to prioritize the safety of its employees during this pandemic. The Company believes the COVID-19 pandemic will continue to impact its productivity, supply chains, distribution networks and other areas of its operation as ongoing concerns regarding the pandemic continue to disrupt the Company’s business and the businesses of its vendors, partners and customers. Although the Company cannot estimate the length and gravity of the impact of the COVID-19 pandemic at this time, the COVID-19 pandemic is expected to have a continuing adverse effect on the Company’s results of operations, financial position and liquidity for at least the remainder of 2020.customer.

OnIn March ~~27,~~ 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to ~~the COVID-19 pandemic.~~ COVID-19. On April 21, 2020, the Company received proceeds from a loan ~~in the amount of $1,717,000 from SVB, as lender,~~ pursuant to the Paycheck Protection Program (“PPP”) of the CARES Act (the “PPP ~~loan”~~Loan”) in the amount of $1.7 million from Silicon Valley Bank (“SVB”), as lender (see Note 8). The Company applied for full forgiveness of the PPP Loan in October 2020. In May 2021, the Company received notification that the PPP Loan and related accrued interest, totaling $1,735,792, were forgiven by the U.S. Small Business Administration (“SBA”), and that the PPP Loan note had been canceled.

In December 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was signed into law to further address the ongoing impacts of COVID-19. The Appropriations Act introduced several additional potential credits and benefits for employers to consider applying for, including, but not limited to, the ability for employers who have previously obtained a PPP Loan to potentially also qualify for Employee Retention Credits (“ERC”), initially created as part of the CARES ~~Act, among~~Act. In March 2021, the American Rescue Plan of 2021 was enacted to, amongst other things, ~~permits NOL carryovers~~extend and ~~carrybacks to offset 100% of taxable income for taxable years beginning before~~expand ERC benefits through December 31, 2021. ~~In addition, the CARES Act allows NOLs incurred in 2018, 2019 and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes.~~ The Company ~~does not currently expect that~~has qualified for certain ERC benefits during the year ended December 31, 2020 and the first three quarters of 2021 and expects to continue to seek out these ~~provisions will have a significant impact on its~~benefits in future periods as appropriate. ERC benefits of approximately $0.6 million and $1.7 million were included in operating expenses as an offset to the related compensation costs in the accompanying condensed consolidated ~~financial statements.~~statements of operations for the three and nine months ended September 30, 2021, respectively.

While there remains uncertainty as to the ultimate impact of ~~the~~ COVID-19, ~~pandemic,~~ the Company has considered the known impacts on its business as of the date ~~of this report~~these condensed consolidated financial statements were issued and has reflected any known or expected impacts in its ~~accompanying~~ condensed consolidated financial statements, including consideration of potential impairment risks to its long-lived assets, potential accounts receivable collection risks and potential impacts to its overall liquidity position.

The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect the accounts of the Company as of September 30, ~~2020~~2021 and for the three and nine months ended September 30, ~~2020~~2021 and ~~2019.~~2020. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America (“~~U.S.~~ GAAP”) for complete financial

statements. The accompanying condensed consolidated financial statements reflect all ~~adjustments consisting of~~ normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s financial position and the results of its operations and cash flows, as of and for the periods presented. The accompanying condensed consolidated balance sheet at December 31, ~~2019~~2020 has been derived from the audited consolidated financial statements at that date but does not include all of the information and disclosures required by ~~U.S.~~ GAAP for annual financial statements. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, ~~2019,~~2020, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 25, ~~2020.~~2021.

All share and per share amounts within the condensed consolidated financial statements and notes thereto have been adjusted to reflect the reverse stock split completed by the Company in November 2020 for all periods and dates presented. See Note 14 for more information about the Company’s reverse stock split.

Management has assessed the Company’s ability to continue as a going concern within one year of ~~the filing~~issuance of ~~this Quarterly Report on Form 10-Q with the SEC.~~these financial statements. The accompanying interim unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of the assets and satisfaction of liabilities in the normal course of business. However, the Company has had recurring operating losses and negative operating cash flows since its inception and has an accumulated deficit of ~~$186.9~~$203.1 million as of September 30, ~~2020.~~2021. As of September 30, ~~2020,~~2021, the Company had working capital of ~~$28.4~~$23.7 million and long-term liabilities of ~~$14.5~~$11.5 million. The Company’s liability balances consist primarily of its debt obligations, including an asset-secured ~~Loan and Security Agreement~~loan with Silicon Valley Bank (the “SVB Term Loan”)~~, the PPP Loan, and a~~ ~~commercial financing agreement extending the payment period related to its director and officer insurance policy~~ ~~(the “Insurance Note”) (see Note 8)~~, as well as an obligation to NuvoGen Research, LLC ~~(“NuvoGen~~(the “NuvoGen obligation”) (see Note 10). ~~While~~Potentially changing circumstances, including COVID-19 uncertainties, may result in the depletion of the Company’s capital resources more rapidly than it currently anticipates, resulting in the Company ~~believes that its existing~~not having adequate resources ~~will be sufficient~~ to fund its planned operations and expenditures for at least the next 12 months ~~from issuance of these condensed consolidated~~and to comply with the financial ~~statements, potential changing circumstances, including COVID-19 uncertainties, may result~~covenant in the ~~depletion of its capital resources more rapidly than it currently anticipates.~~Loan and Security Agreement for the SVB Term Loan (the “Loan Agreement”). These circumstances raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying ~~interim unaudited~~ condensed consolidated financial statements do not include any adjustments that may result from the outcome of these uncertainties.

The Company will need to raise additional capital to fund its operations and service its long-term debt obligations until its revenue reaches a level sufficient to provide for self-sustaining cash flows. There can be no assurance that additional capital will be available on acceptable terms, or at all, or that the Company’s revenue will reach a level sufficient to provide for self-sustaining cash flows. In addition, the Company must comply with a financial covenant in the SVB Term Loan requiring the Company to maintain ~~a certain~~unrestricted cash of not less than the greater of (i) $12.5 million and (ii) an amount equal to six times the amount of ~~unrestricted cash under its SVB Term Loan.~~the Company’s average monthly Cash Burn (as defined in the Loan Agreement) over the trailing three months. If sufficient additional capital is not available as and when needed, the Company may have to delay, scale back or discontinue one or more product development programs, curtail its commercialization activities, significantly reduce expenses, sell assets (potentially at a discount to their fair value or carrying value), enter into relationships with third parties to develop or commercialize products or technologies that the Company otherwise would have sought to develop or commercialize independently, cease operations altogether, pursue a sale of the Company at a price that may result in a significant loss on investment for its stockholders, file for bankruptcy or seek other protection from creditors, or liquidate all assets. In addition, if the Company defaults under ~~its term loan agreement, its lenders~~the Loan Agreement, SVB could accelerate the payment of the SVB Term Loan and ultimately foreclose on ~~its~~the Company’s assets.

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents ~~available-for-sale debt securities~~ and ~~uncollateralized~~ accounts receivable. The Company maintains the majority of its cash balances in the form of cash deposits in bank checking and money market

accounts in amounts in excess of federally insured limits. Management believes, based upon the quality of the financial institution, that the credit risk with regard to these deposits is not significant. ~~The available-for-sale debt securities are comprised primarily of investments in U.S. Treasury and high-quality debt securities.~~

The Company sells its instrument, related consumables, sample processing services, custom RUO assay design and collaborative development services primarily to biopharmaceutical companies, academic institutions and molecular labs. The Company routinely assesses the financial strength of its customers and credit losses have been minimal to date.

The Company currently relies on a single supplier to produce a subcomponent used in its HTG EdgeSeq processors. A loss of this supplier could significantly delay the delivery of processors, which in turn could materially affect the Company’s ability to generate revenue.

The preparation of financial statements in conformity with ~~U.S.~~ GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company’s ~~significant~~ estimates include revenue recognition, stock-based compensation expense, bonus and warranty accrual, income tax valuation allowances and reserves, recovery of long‑lived assets, lease liability, inventory obsolescence and ~~inventory valuation and~~ valuation of inventory, accounts receivable and available-for-sale securities. Actual results could materially differ from those estimates, especially in light of the significant uncertainty that remains as to the full impact of ~~the~~ COVID-19 ~~pandemic~~ on the Company’s operations, as well as those of its workforce, supply chains, distribution networks and those of its customers.

There have been no material changes in the Company’s significant accounting policies from those previously disclosed in the consolidated financial statements included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 25, ~~2020.~~

~~The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the accompanying condensed consolidated statements of cash flows.~~

In October 2017, the Company received $3.0 million in gross proceeds from, and issued a subordinated convertible promissory note (the “QNAH Convertible Note”) in that principal amount to, QIAGEN North American Holdings, Inc. (“QNAH”). Amounts included in restricted cash represented those required to be set aside in escrow under the terms of the MidCap Term Loan to collateralize the payment that was due upon maturity of the QNAH Convertible Note (see Note 8). The balance of restricted cash was released to the Company on June 25, 2020 in conjunction with the extinguishment of the QNAH Convertible Note with proceeds from the SVB Term Loan (see Note 8). 2021.

The carrying value of financial instruments classified as current assets and current liabilities approximate fair value due to their liquidity and short-term nature. Investments that are classified as available-for-sale are recorded at fair value, which is determined using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The carrying value of the SVB Term Loan (see Note 8) is estimated to approximate its fair value as the interest rate approximates the market rate for debt with similar terms and risk characteristics.

The NuvoGen obligation relates to an asset purchase transaction with a then-common stockholder of the ~~Company.~~Company (see Note 10). As of September 30, ~~2020,~~2021, the estimated aggregate fair value of the NuvoGen obligation is approximately ~~$4.5~~$4.7 million, determined using a Monte Carlo simulation with key assumptions including future revenue, volatility, discount and risk-free rates. ~~The estimated fair value of~~

~~Effective January 1, 2019, the Company accounts for its leases under~~ Financial Accounting Standards Board (“FASB”), issued Accounting Standards Codification (“ASC”) 842. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the condensed consolidated balance sheets as both right-of-use assets and lease liabilities, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and right-of-use assets are amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. For financing leases, interest on the lease liability and the amortization of the right-of-use asset result in front-loaded expense over the lease term. Variable lease expenses are recorded to rent expense as incurred.

In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components for all classes of assets currently under lease, including facilities, copiers and computer equipment. The Company excludes short-term leases having initial terms of 12 months or less from as an accounting policy election and recognizes rent on short-term leases on a straight-line basis over the lease term for these leases.

~~In August 2018, the FASB issued Accounting Standards~~“FASB Codification”) Update (“ASU”) No. ~~2018-13,~~ ~~Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement~~2020-10, Codification Improvements (“Update No. 2020-10”), which ~~makes~~amended a ~~number~~variety of ~~changes meant~~topics in the FASB Codification in order to ~~add, modify or remove certain disclosure requirements associated with~~improve the ~~movement against or hierarchy associated with Level 1, Level 2~~consistency of the Codification and ~~Level 3 fair value measurements. The new standard~~the application thereof, while leaving GAAP unchanged. Update No. 2020-10 was effective for fiscal years beginning after December 15, ~~2019, including interim periods within those fiscal years with early adoption permitted, including adoption in an interim period.~~2020 for public business entities. The Company’s adoption of this standard on January 1, ~~2020~~2021 did not have a material impact on its condensed consolidated financial statements or related footnote disclosures.

In ~~November 2018,~~December 2019, the FASB issued ASU No. ~~2018-18,~~2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which ~~amended ASC 808,~~ ~~Collaborative Arrangements~~is intended to simplify various aspects of the accounting for income taxes.

The following are new FASB ASUs that had not been adopted by the Company as of September 30, ~~2020:~~2021:

In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current ~~U.S.~~ GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and also simplifies the diluted earnings per share calculation in certain areas. The standard is effective for public business entities, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years and interim periods within those fiscal years, beginning after December 15, 2021. For all other entities, the standard will be effective for fiscal years beginning after December 15, 2023. Early adoption is permitted, ~~but no earlier than fiscal years beginning after December 15, 2020,~~ and adoption must be as of the beginning of the Company’s annual fiscal year. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

~~In March 2020, the FASB issued ASU No. 2020-04,~~ ~~Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting~~ (“ASU 2020-04”), which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted

accounting principles to transactions affected by reference rate reform if certain criteria are met. These transactions include: contract modifications, hedging relationships, and sale or transfer of debt securities classified as held-to-maturity. Entities may apply the provisions of the new standard as of the beginning of the reporting period when the election is made (i.e. as early as the first quarter 2020). Unlike other topics, the provisions of this update are only available until December 31, 2022, when the reference rate replacement activity is expected to have completed. ~~The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures and has yet to elect an adoption date.~~

~~In December 2019, the FASB issued ASU No. 2019-12,~~ ~~Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes~~ (“ASU 2019-12”), which is intended to simplify various aspects of the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses, which was subsequently amended by ASU 2018-19, ASU 2019-10 and ASU 2020-02, and requires the measurement of expected credit losses for financial instruments carried at amortized cost held at the reporting date based on historical experience, current conditions and reasonable forecasts. The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. With the issuance of ASU 2019-10 in November 2019, the standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2022. The Company will continue to assess the possible impact of this standard, but currently does not expect the adoption of this standard will have a significant impact on its consolidated financial statements, given the high credit quality of the obligors to its available-for-sale debt securities and its history of minimal bad debt expense relating to trade accounts receivable.

Inventory, net of allowance, consisted of the following as of the dates indicated:

For the three and nine months ended September 30, 2021, the Company recorded adjustments to provision for excess inventory of $54,636 and $60,143, respectively. For the three and nine months ended September 30, 2020, the Company recorded adjustments to provision for excess inventory of $10,530 and $12,202, respectively. ~~For the three and nine months ended September 30, 2019, the Company recorded adjustments to provision for excess inventory of $81,582 and $126,582, respectively.~~ Adjustments in these periods to the allowance for estimated shrinkage, obsolescence and excess inventory have been included in cost of product and product-related services revenue in the accompanying condensed consolidated statements of operations.

HTG EdgeSeq instruments at customer locations under evaluation agreements are included in finished goods inventory. Finished goods inventory under evaluation as of September 30, ~~2020~~2021 was ~~$104,950~~$169,042 compared ~~to $79,338~~with $50,855 as of December 31, ~~2019.~~2020.

Financial assets and liabilities measured at fair value are classified in their entirety in the fair value hierarchy based on the lowest level input significant to the fair value measurement. The following table classifies the Company’s financial assets and liabilities measured at fair value on a recurring basis atas of September 30, ~~2020~~2021 and December 31, ~~2019~~2020 in the fair value hierarchy:

There are no other financial instruments subject to fair value measurement on a recurring basis. Transfers to and from Levels 1, 2 and 3 are recognized at the end of the reporting period. There were no0 transfers between levels for the three and nine months ended September 30, ~~2020~~2021 or ~~for~~ the year ended December 31, ~~2019.~~2020.

Level 1 instruments include investments in money market ~~funds and U.S. Treasuries.~~funds.

The Company defines active markets for debt instruments based on both the average daily trading volume and the number of days with trading activity. Level 2 instruments include corporate debt ~~securities.~~securities, including commercial paper and corporate bonds. Valuations of Level 2 instruments can be verified to quoted prices, recent trading activity for identical or similar instruments, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. Consideration is given to the nature of the quotations (e.g., indicative or firm) and the relationship of recent market activity to the prices provided from alternative pricing sources.

Fair values of these assets are based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. These valuation models and analytical tools use market pricing or similar instruments that are both objective and publicly available, including matrix pricing or reported trades, benchmark yields, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids and/or offers. The Company did not adjust any of the valuations received from these third parties with respect to any of its Level 1 or 2 securities for the nine-month period ended September 30, ~~2020~~2021 or the ~~year-ended~~year ended December 31, ~~2019~~2020 and did not have any Level 3 financial assets or liabilities during either of these periods.

The Company’s portfolio of available-for-sale securities consists of ~~U.S. Treasuries and~~ high credit quality corporate debt securities. The following is a summary of the Company’s available-for-sale securities atas of September 30, ~~2020~~2021 and December 31, ~~2019:~~2020:

For debt securities, the Company determines whether it intends to sell or if it is more likely than not that it will be required to sell impaired securities. This determination considers current and forecasted liquidity requirements, regulatory and capital requirements and securities portfolio management. For all impaired debt securities for which there was no intent or expected requirement to sell, the evaluation considers all available evidence to assess whether it is likely the amortized cost value will be recovered. The Company conducts a regular assessment of its debt securities with unrealized losses to determine whether securities have other-than-temporary impairment considering, among other factors, the nature of the securities, credit rating or financial condition of the issuer, the extent and duration of the unrealized loss, expected cash flows of underlying collateral, market conditions and whether the Company intends to sell or it is more likely than not that the Company will be required to sell the debt securities. As the Company did not have any unrealized losses as of September 30, 2020, there were no ~~other-than-temporary impairments of its available-for-sale securities.~~

The SVB Term Loan bears interest at a floating rate equal to the greater of 2.50% above the Prime Rate (as defined in the Loan Agreement) and 5.75%. Interest on the SVB Term Loan is due and payable monthly in arrears. The SVB Term Loan ~~has~~originally required interest-only payments through June 30, 2021. ~~The interest only period may be extended for six months upon~~As a result of the Company’s achievement of an equity milestone ~~as fully~~ defined in the Loan ~~Agreement.~~Agreement during the quarter ended June 30, 2021, the interest-only period has been extended for six months.

The remaining principal repayments due under the SVB Term Loan as of September 30, ~~2020~~2021 are as follows for each fiscal year:

On April 21, 2020, the Company received proceeds from a loan in the amount of ~~$1,717,000~~$1.7 million from SVB, as lender, pursuant to the ~~Paycheck Protection Program (“PPP”) of the CARES Act.~~PPP. The PPP Loan iswas evidenced by a promissory note, ~~(the “Note”)~~which bore interest at an annual rate of 1%, ~~which contains~~and contained customary events of default relating to, among other things, payment defaults and breaches of representations, warranties or terms of the PPP Loan documents.

Beginning on March 21, 2021, the Company is required to make 14 equal monthly payments of principal and interest. The PPP Loan may be prepaid by the Company at any time prior to maturity with no prepayment penalties. The proceeds from the PPP Loan may only be used fordocumented payroll costs (including benefits), rent and utility obligations, and interest on certain of the Company’s other debt ~~obligations.~~

All or a portion of the PPP Loan may be forgiven by the U.S. Small Business Administration (“SBA”) upon application and documentation by the Company of expenditures in accordance with the SBA requirements. Under the CARES Act and PPP Flexibility Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments, covered mortgage interest and covered utilitiesobligations incurred during the 24-week period beginning on the date of loan ~~approval.

The Company applied for full PPP Loan forgiveness in October 2020. ~~However, there can be no assurance given~~

On May 26, 2021 the Company received notification from SVB that the PPP Loan and related accrued interest was forgiven in full by the SBA, and the PPP Loan note had been canceled. Accordingly, the Company ~~will obtain~~recorded a gain on forgiveness of the PPP Loan ~~in whole or in part.

On April 27, 2020, the Company entered into a commercial financing agreement to extend the payment period related to its director and officer insurance ~~policy.~~policy (the “2020 Insurance Note”). The 2020 Insurance Note required a down payment to be made upon signing the agreement equal to approximately $0.2 million. The unpaid premium balance of approximately $0.7 million was financed at an annual rate of 3.61% and was repaid in nine equal monthly payments of principal and interest through February 2021.

On May 5, 2021, the Company entered into a new commercial financing agreement to extend the payment period related to its director and officer insurance policy (the “2021 Insurance Note”). The 2021 Insurance Note required a down payment to be made upon signing the agreement equal to approximately $0.4 million. The remaining unpaid premium balance of approximately $0.7 million has been financed at an annual rate of 3.57% and is ~~being~~to be repaid in nine equal monthly payments of principal and interest beginning on in June ~~6, 2020.~~2021.

The Company had product and product-related services revenue consisting of revenue from the sale of instruments and consumables and the use of the HTG EdgeSeq proprietary technology to process samples and design custom RUO assays for the three and nine months ended September 30, ~~2020~~2021 and ~~2019~~2020 as follows:

~~Because~~As the Company’s agreements for product and product-related services revenue have an expected duration of one year or less, the Company has elected the practical expedient in ASC 606-10-50-14(a) to not disclose information about its remaining performance obligations.

The delivery of each instrument and the related installation and calibration are considered to be a single performance obligation, as the HTG EdgeSeq instrument must be professionally installed and calibrated prior to use. Instrument product revenue is generally recognized upon installation and calibration of the instrument by field service engineers, which represents the point at which the customer has the ability to use the instrument and has accepted the asset. Installation generally occurs within one month of instrument shipment.

The delivery of each consumable is a separate performance obligation. Consumables revenue is recognized upon transfer of control, which represents the point when the customer has legal title and the significant risks of ownership of the asset. The Company’s standard terms and conditions provide that no right of return exists for instruments and consumables, unless replacement is necessary due to delivery of defective or damaged product. Customer payment terms vary but are typically between 30 and 90 days of revenue being earned from shipment or delivery, as applicable.

Shipping and handling fees charged to the Company’s customers for instruments and consumables shipped are included in the accompanying condensed consolidated statements of operations as part of product and product-related services revenue. Shipping and handling costs for sold products shipped to the Company’s customers are included in the accompanying condensed consolidated statements of operations as part of cost of product and product-related services revenue.

For sales of consumables in the United States, standard delivery terms are FOB shipping point, unless otherwise specified in the customer contract, reflecting transfer of control to the customer upon shipment. Standard delivery terms for sales to customers outside of the United States are FOB delivery point, unless otherwise specified in the customer contract. The Company has elected the practical expedient to account for shipping and handling as activities to fulfill the promise to transfer the consumables. ~~The Company uses a most likely amount approach to estimate variable consideration arising from its rebate program. The Company’s variable consideration from its rebate program is constrained.~~

The Company provides instruments to certain customers under reagent rental agreements. Under these agreements, the Company installs an instrument in the customer’s facility without a fee and the customer agrees to purchase consumable products at a stated price over the term of the agreement; in some instances, the agreements do not contain a minimum purchase requirement. Terms range from several months to multiple years and may automatically renew in several month or multiple year increments unless either party notifies the other in advance that the agreement will not renew. The Company measures progress toward complete satisfaction of this performance obligation to provide the instrument and deliver the consumables using an output method based on the number of consumables delivered in relation to the total consumables to be provided under the reagent rental agreement. This is considered to be representative of the delivery of outputs under the arrangement and the best measure of progress because the customer benefits from the instrument only in conjunction with the consumables. The Company expects to recover the cost of the instrument under the agreement through the fees charged for consumables, to the extent sold, over the term of the agreement.

In reagent rental agreements, the Company retains title to the instrument and title is transferred to the customer at no additional charge at the conclusion of the initial arrangement. The cost of the instrument is amortized on a straight-line basis over the term of the arrangement, unless there is no minimum consumable product purchase, in which case the instrument would be expensed as cost of ~~product and product-related services~~ ~~revenue upon installation. Cost to maintain the instrument while title remains with the Company is charged to selling, general and administrative expense as incurred.~~

The Company also provides sample preparation and processing services and molecular profiling of retrospective cohorts for its customers through its VERI/O laboratory, whereby the customer provides samples to be processed using HTG EdgeSeq technology specified in the order. Customers are charged a per sample fee for sample processing services which is recognized as revenue upon delivery of a data file to the customer showing the results of testing and completing delivery of the agreed upon service. This is when the customer can use and benefit from the results of testing and the Company has the present right to payment.

The Company enters into custom RUO assay design agreements that may generate up-front fees and subsequent payments that might be earned upon completion of design process phases. The Company measures progress toward complete satisfaction of its performance obligation to perform custom RUO assay design using an output method based on the costs incurred to date compared with total expected costs, as this is representative of the delivery of outputs under the arrangements and the best measure of progress. However, because in most instances the assay design fees are contingent upon completion of each phase of the design project and the decision of the customer to proceed to the next phase, the amount to be included in the transaction price and recognized as revenue is limited to that which the customer is contractually obligated to pay upon completion of that phase, which is when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Changes in estimates of total expected costs are accounted for prospectively as a change in estimate. From period to period, custom RUO assay design service revenue can fluctuate substantially based on the completion of design-related phases.

The Company did not recognize any custom RUO assay design revenue from performance obligations that were satisfied in previous periods for either the three and nine months ended September 30, 2020, compared with $0 and $41,137 for the three and nine months ended September 30, 2019, respectively.

The Company enters into collaborative development services agreements with biopharmaceutical companies for the development of NGS-based companion diagnostic assays in support of and in conjunction with, biopharmaceutical companies’ drug development programs. These collaborative development services agreements may generate upfront fees, and in some cases subsequent milestone payments that may be earned upon completion of certain product development milestones or activities. The Company follows ASC 606 ~~Revenue from Contracts with Customers~~ and ASC 808 ~~Collaborative Arrangements~~ to determine the appropriate recognition of revenue under ~~our~~its collaborative research, development and commercialization ~~agreements that contain multiple elements.~~ agreements. Because each SOW had an expected duration of one year or less, the Company elected the practical expedient in ASC 606-10-50-14(a) not to disclose information about its remaining performance obligations for each SOW.

For the three and nine months ended September 30, 2020, ~~and 2019,~~ collaborative development services revenue was generated through statements of work entered into ~~under the Governing Agreement with QML as follows:~~

~~In November 2016,~~ (the “Governing Agreement”) with QIAGEN Manchester Limited (“QML”). Under these agreements, the ~~Company entered into the Governing Agreement, which created the framework for QML and the Company to combine their~~Companies combined technological and commercial strengths to offer biopharmaceutical companies a complete NGS-based solution for the development, manufacture and commercialization of companion diagnostic ~~assays. Under the Governing Agreement, the parties jointly sought companion diagnostic programs~~assays in support of and in conjunction with, biopharmaceutical ~~companies,~~companies’ drug development programs. Remaining agreed upon procedures associated with ~~QML entering into sponsor project agreements with interested biopharmaceutical companies for specified projects, and QML and the Company entering into~~these statements of work which set forth the rights and obligations of QML and the Company with respect to each project. In November 2019, the Company elected to terminate the Governing Agreement with QML as a result of QML’s material breach of the Governing Agreement, including QML’s failure to develop an in vitro diagnostic (“IVD”) version of its GeneReader sequencing platform for development of PDP Assays. The Company’s termination of the Governing Agreement did not terminate active statements of work under the Governing Agreement.

The Company has determined that SOW Two and SOW Three (each defined below) are collaborative arrangements and that QML meets the definition of a customer under ASC 606. Additionally, each SOW is a separate contract with a single performance obligation to provide development services. Under each SOW, QML pays the Company a monthly fee for development work performed by the Company and its subcontractors (collectively, the “Monthly Fee”). The Monthly Fee is based on the employee and materials costs incurred during the month, which is subject to significant variability from period to period and unknown until the costs are incurred. Therefore, the Monthly Fee, which is based on use of hours and costs as a measure of progress, is included in the transaction price and recognized as revenue over time when the costs are incurred, and the Monthly Fee is billed to QML. It is at this time that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. The Company and QML also share any net profits resulting from performance of the development work as determined pursuant to the Governing Agreement. Such profit-sharing payment(s) are deemed to be variable consideration using the expected value method and are included in the transaction price upon completion of the respective SOW deliverables, acceptance of corresponding deliverables, and the mutual agreement by QML and the Company on the calculation of net profit, which is when it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur.

Because each SOW has an expected duration of one year or less, the Company has elected the practical expedient in ASC 606-10-50-14(a) to not disclose information about its remaining performance obligations for each SOW.

In October 2017, the Company and QML entered into the second statement of work under the Governing Agreement (“SOW Two”), which was made effective as of June 2, 2017 (“Onset Date”). The Company and QML amended SOW Two twice in August 2018 and two additional times, in September 2018 and in February 2019. SOW Two addresses development activities conducted by the Company and QML since the Onset Date and those expected to be further conducted by the parties in connection with what is expected to be a multi-stage project leading to the potential development and commercialization of an NGS-based companion diagnostic assay in support of one or more therapeutic development and commercialization programs for a third-party biopharmaceutical company.

The initial-phase investigational-use-only (“IUO”) development activities under SOW Two and the first three amendments related to next phases, which include the use of the IUO assay developed in the initial-phase in a retrospective clinical trial and in additional disease indications, have been completed. The fourth amendment of SOW Two, effective as of February 5, 2019, contemplates the use of the IUO assay in multiple biopharmaceutical company clinical trials and additional development activities which could potentially

~~be included in a future companion diagnostic regulatory submission.~~ ~~As of September 30, 2020, development activities agreed upon in the fourth amendment are ongoing and expected to be~~were completed in the ~~fourth quarter of 2020.~~

~~Revenue of approximately $0.1 million~~prior year and ~~$0.5 million inclusive of SOW Two Monthly Fees and approximately $0.1 million and $0.1 million of SOW Two profit-sharing payments has been included in~~no additional collaborative development services revenue in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2020, respectively. Revenue of approximately $0.6 million and $2.2 million, inclusive of SOW Two Monthly Fees and approximately $0.3 million and $0.4 million of SOW Two profit-sharing payments hasprograms have been included in collaborative development services revenue in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2019, respectively. Accounts receivable relating to SOW Two of approximately $0.1 million and $0.2 million remained in the accompanying condensed consolidated balance sheetsentered into as of September 30, 2020 and December 31, 2019, respectively. Costs relating to development activities conducted by the Company pursuant to SOW Two of less than $0.1 million and approximately $0.4 million have been included in research and development expense in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2020, respectively, compared with approximately $0.2 million and $1.3 million for the three and nine months ended September 30, 2019, respectively.2021.

In January 2018, the Company and QML entered into a third statement of work under the Governing Agreement (“SOW Three”) and amended SOW Three in September 2018. SOW Three relates to development activities for an NGS-based clinical-trial assay (“SOW Three Project”) in connection with a sponsor project agreement between QML and a pharmaceutical company (“Pharma Three”). Initial assay development activities under SOW Three have been completed, and the first amendment to SOW Three provides for the development of an IUO assay, subsequent retrospective testing of clinical trial samples, design verification and, subject to satisfactory achievement of relevant performance and regulatory milestones, regulatory submissions in the United States and European Union necessary for the commercialization of a companion diagnostic for a corresponding Pharma Three drug. As of September 30, 2020, the Company and QML are on hold pending customer decision as to whether to proceed with next phase contract activities.

There was no revenue recognized, or development costs incurred relating to SOW Three for the three and nine months ended September 30, 2020. Revenue of approximately $0.5 million and $0.8 million reflecting SOW Three Monthly Fees has been included in collaborative development services revenue in the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2019, respectively. Accounts receivable relating to SOW Three of $0 and approximately $0.8 million remained in the condensed consolidated balance sheets as of September 30, 2020 and December 31, 2019, respectively. Costs relating to development activities conducted by the Company pursuant to SOW Three of approximately $0.3 million and $0.6 million have been included in research and development expense in the condensed consolidated statements of operations for the three and nine months ended September 30, 2019, respectively.

Contract assets represent the Company's right to consideration in exchange for goods or services that the Company has transferred to a customer, for which rights to payment are conditional upon something other than the passage of time. Contract assets of approximately $42,000 and $0 were included in prepaid expenses and other in the accompanying condensed consolidated balance sheets as of September 30, 2020 and December 31, 2019, respectively.

The Company ~~receives~~may receive up-front payments from customers for custom RUO assay design ~~services,~~ and ~~occasionally for~~ sample processing services. ~~Payments~~In addition, payments for instrument extended warranty contracts are required to be made in ~~advance as are payments for certain agreed-upon capital purchases required for collaborative development service projects.~~advance.

Changes in the Company’s contract liability were as follows as of the dates indicated:

Pursuant to the Company’s asset purchase agreement with NuvoGen Research, LLC (“NuvoGen”), as amended, the Company is obligated to pay NuvoGen annually the greater of $400,000 or 6% of annual revenue until the obligation is paid in full. In addition to fixed quarterly payments of $100,000, there were $51,225 of revenue-based payments ~~of less than $0.1 million and approximately $0.2 million were~~ payable as of September 30, ~~2020 and~~2021, compared with approximately $54,777 of revenue-based payments payable as of December 31, ~~2019, respectively.~~2020.

The Company leases office space under agreements classified as operating leases. The Company’s active leases as of September 30, 2021 are for office and manufacturing space in Tucson, Arizona, which expire in 2025. The Company’s leases do not include any contingent rental payments, impose any financial restrictions, or contain any residual value guarantees.

The Company amended its Tucson facility leases in December 2020 to extend the terms of the leases for one year, through January 31, 2022 and again in September 2021 to extend the terms of the leases for three years, through January 31, 2025. The lease extensions were treated as lease modifications for accounting purposes, and allow for an additional extension of two years on the same terms and conditions of the existing amended lease agreement, except that the lease rates would be adjusted to reflect lease rates applicable to like-kind buildings within the market at the time that the Company elects to exercise the extension options, but in no ~~significant modifications or financial events relating~~event less than the last applicable rental rate. The Company has not accounted for these renewal options in the calculation of the lease liabilities and right-of-use assets as the Company is not reasonably certain to exercise the options.

In the first quarter of 2021, the Company closed its development laboratory in San Carlos, California and, as a result, $0.2 million of operating right-of-use assets related to the abandonment of the laboratory were written off to research and development ~~agreement entered into~~expense during the nine months ended September 30, 2021.

The table below summarizes other information related to the Company’s operating leases:

Remaining maturities of the Company’s operating leases, excluding short-term leases, included in operating lease liabilities – non - current in the condensed consolidated balance sheets as of September 30, 2021 are as follows:

The Company has a number of computer and copier equipment leases that are classified as financing leases. Incremental borrowing rates used to discount future lease payments in calculating lease liabilities were estimated by reference to information received by the Company from bankers regarding estimated current borrowing rates for collateralized loans with ~~Illumina, Inc. since~~similar amount and duration as the ~~disclosures made in Part II, Item 8, Consolidated Financial Statements~~leases. The Company does not have any material financing leases where it acts as a lessor.

The table below summarizes other information related to the Company’s financing leases:

As of September 30, 2021, remaining maturities of the Company’s financing leases are as follows:

Financing lease liabilities net of discount of $52,635, of which $17,558 and $35,077 were included in other current liabilities and other non-current liabilities, respectively, and financing right-of-use assets of $48,269, were included in property and equipment, net, in the ~~Company’s Annual Report on Form 10-K, filed with the SEC on March 25, 2020.~~condensed consolidated balance sheet as of September 30, 2021.

Basic loss per common share is computed by dividing net loss allocable to common stockholders by the weighted average number of shares of common stock or common stock equivalents outstanding. Diluted loss per common share is computed similar to basic loss percommon share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock.

In connection with the Securities Purchase Agreement (see Note 13), the Company issued and sold an aggregate of 5,411,687 pre-funded warrants exercisable for an aggregate of 5,411,687 shares of common stock. The total exercise price of the pre-funded warrants is $0.65 per share, $0.64 of which was pre-funded and paid to the Company upon issuance of the pre-funded warrants. The remaining exercise price of the pre-funded warrants is ~~$0.01 per share.~~ ~~In March 2020, 3,176,762 of the pre-funded warrants were exercised for proceeds of $31,768.~~ ~~The remaining pre-funded warrants are immediately exercisable and do not expire. As the remaining shares underlying the pre-funded warrants are issuable for nominal consideration of $0.01 per share,~~ 2,234,925 in common shares underlying the unexercised pre-funded warrants were considered outstanding for purposes of the calculation of loss per share, as of the three and nine months ended September 30, 2020.

The following ~~outstanding options, warrants, restricted~~common stock ~~units and debt conversion option~~equivalents were excluded from the computation of diluted net loss per share for the periods presented because their effect would have been anti-dilutive:

In connection with certain of its redeemable convertible preferred stock issuances, convertible debt financings and other financing arrangements, the Company has issued warrants for shares of its common stock and various issues of its redeemable convertible preferred stock, which have since been converted to common stock warrants.

In ~~September 2019, in~~ connection with the Securities Purchase Agreement (see Note ~~13)~~14), the Company issued and sold ~~an aggregate of 5,411,687~~ pre-funded warrants exercisable for an aggregate of ~~5,411,687~~360,779 shares of common stock. The total exercise price of the pre-funded warrants is ~~$0.65~~$9.75 per share, ~~$0.64~~$9.60 of which was pre-funded and paid to the Company upon issuance of the pre-funded warrants. The remaining exercise price of the pre-funded warrants is ~~$0.01~~$0.15 per share. In March 2020, ~~3,176,762~~211,784 of the pre-funded warrants were exercised for proceeds of $31,768. ~~As of September 30, 2020,~~In June 2021, the remaining 148,995 pre-funded warrants ~~remain outstanding and are exercisable by~~were exercised on a cashless, net exercise basis, resulting in the ~~holders at any time.~~issuance of 144,881 shares of common stock.

In connection with the SVB Term Loan ~~Agreement~~ (see Note 8), the Company granted to SVB a warrant to purchase up to ~~643,413~~42,894 shares of the Company’s common stock at a purchase price of ~~$0.7771~~$11.6565 per share. The warrant will expire on June 24, 2030 and may be exercised for cash or at the election of the holder on a cashless, net exercise basis.

The following table shows the common stock warrants outstanding as of September 30, ~~2020:~~2021:

On November 20, 2020, the Company completed a reverse stock split of its outstanding shares of common stock pursuant to which every fifteen (15) shares of issued and outstanding common stock were exchanged for one share of its common stock. NaN fractional shares were issued in the reverse stock split. Instead, fractional shares that would have otherwise resulted from the stock split were purchased by us at the applicable percentage of $4.27 per share. All share and per share amounts included within these financial statements have been retrospectively adjusted to reflect the reverse stock split.

In September 2019, concurrently with the closing of an underwritten public offering, the Company entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional accredited investors (the “Purchasers”), pursuant to which the Company sold to the Purchasers, in a private placement transaction, ~~an aggregate of 5,411,687 pre-funded~~ warrants to purchase up to an aggregate of ~~5,411,687~~360,779 shares of ~~our~~its common stock (“Warrant Shares”), at a price of ~~$0.64~~$9.60 per warrant (which ~~$0.64~~$9.60 price relates to the pre-funded portion of the total ~~$0.65~~$9.75 exercise price per share). Each pre-funded warrant has a remaining exercise price of ~~$0.01~~$0.15 per share and became immediately exercisable upon issuance, subject to certain beneficial ownership limitations.

The exercise price of the pre-funded warrants will be subject to adjustment in the event of any stock dividends and splits, recapitalization, reorganization or similar transaction, as described in the pre-funded warrants. The pre-funded warrants are exercisable on a “cashless” basis in certain circumstances.

The pre-funded warrants and the Warrant Shares were not registered under the Securities Act and were offered pursuant to the exemption provided in Section 4(a)(2) under the Securities Act and Rule 506(b) promulgated thereunder. Pursuant to the Securities Purchase Agreement, the Company filed a registration statement on Form S-3 on October 11, 2019 to register the resale of the Warrant Shares, which registration statement was declared effective by the SEC on November 26, 2019. Each Purchaser was an “accredited investor” as defined in Rule 501(a) under the Securities Act.

Cantor Fitzgerald & Co. (the “Placement Agent”) acted as the sole placement agent in connection with the private placement of the warrants. Pursuant to a Placement Agency Agreement between the Company and the Placement Agent, the Company agreed to pay the Placement Agent a cash fee equal to 6% of the gross proceeds from the sale of the pre-funded warrants, and to provide reimbursement for certain out-of-pocket expenses. Upon closing, the Company received approximately $3.1 million in net proceeds from the sale of the pre-funded warrants in the private placement, which did not include proceeds subsequently received or that may be received upon exercise of the pre-funded warrants, after deducting the Placement Agent fee and other expenses. In March 2020, ~~3,176,762~~211,784 of the pre-funded warrants were exercised for additional proceeds of $31,768. In June 2021, the remaining 148,995 pre-funded warrants were exercised on a cashless, net exercise basis, resulting in the issuance of 144,881 shares of the Company’s common stock.

In November 2019, the Company entered into a Controlled Equity Offering Sales Agreement (the “Cantor Sales Agreement”) with Cantor as the sales agent, pursuant to which the Company may offer and sell, from time to time, through Cantor, shares of its common stock, par value $0.001 per share, by any method deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act (the “ATM Offering”). The shares are offered and sold pursuant to the Company’s shelf registration statement on Form S-3 (File No. 333-229045).

During the nine months ended September 30, ~~2020,~~2021, the Company sold ~~10,436,016~~2,050,879 shares of common stock under the ATM Offering at then-market prices for total gross proceeds of approximately ~~$6.7~~$11.0 million. After ~~deferred offering costs included as non-current assets in the condensed balance sheets as of December 31, 2019 of approximately $0.1 million and~~ paying sales commissions owed in connection with the ATM Offering of approximately ~~$0.2~~$0.3 million, the Company’s aggregate net proceeds for the nine months ended September 30, ~~2020~~2021 were approximately ~~$6.4~~$10.7 million.

On February 25, 2020, the Company entered into an Exchange and Purchase Agreement (the “Exchange Agreement”) with certain accredited investors (the “Investors”) pursuant to which the Company agreed to (i) issue to the Investors an aggregate of 41,100 shares of its newly designated Series A Convertible Preferred Stock, par value $0.001 per share (“Series A Preferred”), in exchange for the Investors surrendering to the Company for cancellation an aggregate of ~~4,110,000~~274,000 shares of its common stock (the “Exchange”) and (ii) sell and issue to the Investors an aggregate of 10,170 shares of Series A Preferred for an aggregate purchase price of ~~$600,030,~~$0.6 million, or $59.00 per share (the “Private Placement”).

Each share of Series A Preferred is convertible into ~~100~~6.67 shares of the Company’s common stock, subject to proportional adjustment and beneficial ownership limitations. In June 2020, certain of the Investors elected to convert 27,500 shares of Series A Preferred to common stock in the aggregate, resulting in the issuance of ~~2,750,000~~183,333 shares of the Company’s common stock. The remaining 23,770

Series A Preferred shares remain outstanding as of September 30, ~~2020.~~2021. In the event of the Company’s liquidation, dissolution or winding up, holders of Series A Preferred will participate pari passu with any distribution of proceeds to holders of the Company’s common stock. Holders of Series A Preferred are entitled to receive dividends on shares of Series A Preferred equal (on an as converted to common stock basis) to and in the same form as dividends actually paid on the Company’s common stock. Shares of Series A Preferred generally have no voting rights, except as required by law.

On March 24, 2020, the Company entered into a purchase agreement ("(“LP Purchase ~~Agreement"~~Agreement”) with Lincoln Park Capital Fund, LLC ("(“Lincoln ~~Park"~~Park”), pursuant to which, upon the terms and subject to the conditions and limitations set forth therein, the Company has the right to sell to Lincoln Park up to $20.0 million of shares of its common stock (“Purchase Shares”) from time to time over the 36-month term of the LP Purchase Agreement.

The Company leases office space and equipment under agreements classified as operating leases that expire on various dates through 2023. The Company’s most significant active leases as of September 30, 2020 are for office and manufacturing space in Tucson, Arizona, which expire in 2021. The Company also leases a development laboratory space in San Carlos, California, which expires in 2023. The Company’s leases do not include any contingent rental payments, impose any financial restrictions, or contain any residual value guarantees. Certain of the Company’s leases include renewal options and escalation clauses; renewal options have not been included in the calculation of the lease liabilities and right-of-use assets as the Company is not reasonably certain to exercise the options. Annual rent increases are included in the calculation of the operating lease right-of-use assets. Variable expenses generally represent the Company’s share of the landlord’s operating expenses and are recorded when incurred. Incremental borrowing rates used to discount future lease payments in calculating lease liabilities were estimated by reference to the rate on the Company’s existing debt, as this represents the cost of borrowing for secured loans of similar duration. The Company does not have any operating lease arrangements where it acts as a lessor.

~~The table below summarizes other information related to the Company’s operating leases:~~

~~As of September 30, 2020, remaining maturities of our operating leases, excluding short-term leases, are as follows:~~

~~The Company has a number of computer and copier equipment leases that are classified as financing leases.~~ Incremental borrowing rates used to discount future lease payments in calculating lease liabilities were estimated by reference to information received by the Company from bankers regarding estimated current borrowing rates for collateralized loans with similar amount and duration as the leases. ~~The Company does not have any material financing leases where it acts as a lessor.~~

~~The table below summarizes other information related to the Company’s financing leases:~~

Our product and service solutions enable targeted RNA profiling using a small amount of biological sample, in liquid or solid forms. Our menu of HTG EdgeSeq assays is automated on our HTG EdgeSeq system, which applies genomic sequencing tools that generate gene expression data in a timely manner utilizing a simplified workflow for customers. We seek to leverage key business drivers in molecular profiling for biomarker analysis and diagnostics, including the acceleration of precision medicine, the migration of molecular testing to NGS-based applications, the movement to smaller and less invasive biopsies, the need for greater diagnostic sensitivity, the need to conform to challenging healthcare economics and the need for automation and an easily deployable workflow, including simplified bioinformatics. ~~For example, these~~These capabilities enable customers to extend the use of limited biological samples for retrospective analysis, gaining further understanding of the molecular drivers of disease with the goal of developing biomarker-driven targeted therapies. We also believe our HTG EdgeSeq technology can be used as a platform technology in clinical applications that will simplify, consolidate and reduce the cost of NGS-based diagnostic workflows and in commercialized companion diagnostic (“CDx”) tests.

Our products include instruments, consumables, including assay kits, and software that, as an integrated platform, automate sample processing and can quickly, robustly and simultaneously profile tens, hundreds or thousands of molecular targets from samples a fraction of the size required by many prevailing technologies. Our objective is to establish our solutions as the standard in molecular profiling, ~~companion diagnostic~~CDx development and molecular diagnostics, and to make their benefits accessible to all molecular labs from research to the clinic. We believe that our target customers and collaborators desire high quality molecular profiling ~~information~~data in a multiplexed panel format from increasingly smaller and less invasive samples, providing our customers and collaborators with ~~the ability to test and~~ the option to analyze such ~~information~~data locally to minimize turnaround time and cost.

Our development efforts over the past 18 months have been primarily focused on completing feasibility and development of the HTG Transcriptome Panel, including supporting our Early Adopter Program (EAP), where approximately 30 scientific collaborators throughout the U.S. and EU have partnered with us to explore potential applications of the HTG Transcriptome Panel in their research and clinical programs. In ~~2014,~~the near future we ~~launched~~expect our EAP collaborators to assist us with customer testimonials, white papers, technical notes and peer-reviewed publications highlighting their use of the HTG ~~EdgeSeq technology, which generates a molecular profiling library for gene expression profiling using NGS.

By leveraging these profiling technologies earlier in the drug discovery process, HTG Therapeutics is expected to generate lead compounds faster, and with potentially more favorable efficacy and toxicity profiles. In addition to the platform technology ~~can enable gene expression~~for molecular profiling, ~~growth~~we are building a full machine learning-based chemical library design platform, which is expected to ~~accelerate~~better predict the binding properties of a drug candidate to its target. Since June 2021, we have expanded HTG Therapeutics with the addition of several highly experienced professionals in leadership positions. Working with our Tucson-based research and development teams, these individuals have engaged several external collaborators who are expected to contribute meaningful cohorts for our initial planned studies to identify development candidates targeting RNA or RNA modifying proteins, which could be relevant in areas such as oncology, immunology, transplant, diabetes and rare disease. These efforts are

aimed at the generation of high-quality primary data from our proprietary profiling platform from known and well annotated cohorts that we ~~make NGS-based gene expression analysis easier~~believe could lead to new pharma partnerships in early-stage drug discovery by the second half of 2022 and ~~more sample sparing.~~beyond. Costs related to this program were approximately 29% and 18% our overall research and development expense for the three and nine months ended September 30, 2021, respectively, but are not expected to have a material impact on our projected operating expense for the remainder of the year.

COVID-19 and international efforts to control its spread have significantly curtailed the movement of people, goods and services worldwide, including in regions where we sell our products and services and conduct our business over the past year. We ~~have two primary sources of revenue:~~experienced a significant slowing in our product and product-related services revenue from the sale of research use only (“RUO”) and CE IVD marked profiling products, sample processing services and custom assay design services to biopharmaceutical companies, academic research centers and molecular testing laboratories; and revenue from collaborative development services for companion diagnostic development programs for biopharmaceutical companies.

Profiling product and product-related services revenue includes customer purchases of our HTG EdgeSeq instrument and related assay kits, design of custom RUO assay kits for customers and the use of our HTG EdgeSeq instrument and RUO assay kits to process samples on the customer’s behalf in our VERI/O laboratory. In addition, we sell two internally developed proprietary CE IVD marked assays, including our HTG EdgeSeq DLBCL Cell of Origin Assay EU and HTG EdgeSeq ALKPlus Assay EU. Additional diagnostic tests are in early stage development in collaboration with our European customers. Our team of field-based and support services employees throughout Europe facilitate our ability to generate product revenue in Europe and to improve our responsiveness to customer needs in that region. While we have closed our applications laboratory in Sausheim, France, we continue to perform sample processing and collaborative development services for our global customer base in our VERI/O laboratory in the United States.

Collaborative development revenue relates to services performed using our HTG EdgeSeq proprietary technology to develop, seek regulatory approval for and commercialize companion diagnostic assays for biopharmaceutical drug candidates and corresponding therapeutics. Collaborative development services revenue recognized to date has been generated primarily pursuant to the Master Assay Development, Commercialization and Manufacturing Agreement between us and QIAGEN Manchester Limited (“QML”) dated November 2016 (the “Governing Agreement”). In November 2019, we terminated the Governing Agreement. Our termination of the Governing Agreement did not terminate active statements of work under the Governing Agreement. On a going-forward basis, we expect to enter into additional collaborative development services arrangements directly with biopharmaceutical company customers, which we believe will result in improved economics from these arrangements and not limit the sequencer platform used for development. In August 2020, we entered into a Commercialization and Distribution Agreement with QML that we believe will provide our customers distribution and commercialization options with QML in the event that a companion diagnostic assay is developed under one of these development services arrangements in the future.

Collaborative development services, as well as laboratory services, represent a services-oriented model. However, we anticipate that these services will be a catalyst toward a product-based strategy as an increase in our menu of diagnostic panels is expected to result in increased demand for our instrument and consumables products in individual laboratories and customer locations.

In March 2020, the World Health Organization announced that a new strain of coronavirus originating in Wuhan, China had become a pandemic. The full impact of the COVID-19 pandemic on our financial condition, liquidity and future results of operations remains fluid and uncertain as of the date of this report. We experienced a significant slowing of product and product-related services revenue generation beginning in March 2020 and ~~we believe this period~~throughout the first half of ~~reduced revenue will continue through at least the remainder of 2020~~2021 due to continued disruptions to our customers’ businesses from the pandemic and, in many instances, their prioritization of projects in areas ~~focus~~ related to COVID-19. We have also experienced limited delays in our development efforts as a result of stay-at-home orders and our efforts to prioritize the safety of our employees during this pandemic. However, all 2020 key development milestones have been met and high priority development efforts have continued, including extensive experiment study planning and analysis, despite operational challenges including more limited activity in our wet labs. We believe the COVID-19 pandemic will continue to impact our productivity, supply chains, distribution networks and other areas of our operation as the pandemic continues to disrupt our business and the businesses of our vendors, partners and customers.

Our 2020 development efforts have been aimed at expansion of our position in translational medicine with our RUO molecular profiling products, including adding to the utility of our targeted oncology, immuno-oncology, autoimmune and micro RNA panels with the addition of new applications and analytical capabilities released in our HTG EdgeSeq Reveal software. This web-based biostatistical analysis software is designed to accelerate customer research by streamlining their statistical analysis of samples processed with our HTG EdgeSeq RUO profiling assays. In addition, we have ~~continued~~experienced extended shipment times and increases in cost of product as ongoing supply chain disruptions have impacted the ability of certain suppliers to ~~reach~~produce the materials necessary to build our product and perform our testing services. Despite the impacts of COVID-19 on our revenue and operations, we met all key development milestones ~~in the development~~throughout 2020 and 2021 to date and have not experienced any substantive manufacturing delays from raw material shortages. While most of our ~~whole transcriptome product toward a planned RUO launch~~customers have now reopened their facilities, it remains unknown whether COVID-19 will continue to materially impact our financial condition, liquidity and future results of operations in ~~2021. This panel is expected~~future periods due to measure approximately 20,000 biomarkers and we believe that it will be a foundational product not only for RUO profiling, but also for our companion diagnostics and potential proprietary diagnostic products. We also expect this product to expand our product offerings outside of oncology and autoimmune and into additional markets such as transplant and diabetes.further shutdowns, social distancing measures or illness.

On April 21, 2020, we received proceeds from a loan in the amount of $1,717,000 (the “PPP Loan”) from Silicon Valley Bank (“SVB”), as lender, pursuant to the Paycheck Protection Program (“PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The PPP Loan matures on April 21, 2022 and bears interest at an annual rate of 1%. All or a portion of the PPP Loan may be forgiven by the U.S. Small Business Administration (“SBA”) upon the SBA’s review and acceptance of the documentation provided with the forgiveness application submitted in October 2020 in accordance with the SBA requirements. Beginning on March 21, 2021, we are required to make 14 equal monthly principal and interest payments on all amounts that are not forgiven. We may prepay the PPP Loan at any time prior to maturity with no prepayment penalties.

In June 2020, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”), as lender, which provides a secured term loan in the principal amount of $10.0 million (the “SVB Term Loan”). The proceeds from the SVB Term Loan were fully funded on the June 25, 2020, and were used, together with cash on hand, to repay in full all outstanding amounts and fees due under the MidCap Credit Facility and the QNAH Convertible Note (see Note 8 to our condensed consolidated financial statements included elsewhere in this report). The SVB Term Loan bears interest at a floating rate equal to the greater of 2.50% above the Prime Rate (as defined in the Loan Agreement) and 5.75%. Interest on the SVB Term Loan is due and payable monthly in arrears. The SVB Term Loan has interest-only payments through June 30, 2021. The interest only period may be extended for six months upon the achievement of an equity milestone as fully defined in the Loan Agreement. The ultimate interest-only period will be followed by equal monthly payments of principal and interest through the maturity date of December 1, 2023.

~~We generate revenue from two primary sources:~~Our product and product-related services revenue ~~from~~is generated through the sale of ~~RUO~~our profiling instruments and ~~CE IVD marked profiling products,~~consumables, sample processing services and custom assay design services to biopharmaceutical companies, academic research centers and molecular testing ~~laboratories; and revenue from collaborative development services for biopharmaceutical companies under our companion diagnostic development programs.~~laboratories.

RUO profiling is currently made available to our customers through product sales and service offerings. Customers can purchase our HTG EdgeSeq instrument and related consumables, which consist primarily of our proprietary molecular profiling panels and other assay components. Customers can also access our technology through contracted services. We perform these services using our HTG EdgeSeq instruments and RUO consumables to process samples in our VERI/O laboratory. Our proprietary technology is also used to develop custom RUO panels which are expected to generate future sample processing or RUO consumables revenue.

~~Collaborative~~We have also previously generated collaborative development services revenue ~~generated to date has primarily related to~~through three statements of work entered into under our ~~Governing~~Master Assay Development, Commercialization and Manufacturing Agreement (the “Governing Agreement”) with ~~QML.~~

QIAGEN Manchester Limited (“QML”). Under these agreements, we and QML combined our technological and commercial strengths to offer biopharmaceutical companies a complete NGS-based solution for the development, manufacture and commercialization of companion diagnostic assays in support of and in conjunction with, biopharmaceutical companies’ drug development programs. Remaining agreed upon procedures associated with these statements of work were completed in the prior year and no additional collaborative development services programs have been entered into as of September 30, 2021. Although we continue to seek potential, new customer collaborations, we currently do not anticipate additional revenue from existing or new collaborative development services programs in 2021.

Total revenue ~~decreased~~increased by ~~67% and 59%~~42% to $2.5 million for the three months ended September 30, 2021, compared with $1.8 million for the three months ended September 30, 2020, reflecting increases in both product and product-related services revenue when compared with the third quarter of 2020. Total revenue increased by approximately 1% to $6.0 million for the ~~three and~~ nine months ended September 30, ~~2020, respectively,~~2021, compared with ~~$5.4 million and $14.4~~$6.0 million for the ~~three and~~ nine months ended September 30, ~~2019, respectively.~~2020. The ~~COVID-19 pandemic has continued to negatively impact our ability to generate direct and collaborative development services~~increase in total revenue ~~since March 2020 as numerous academic and biopharmaceutical company customers’ facilities have been closed or partially closed due to~~for the pandemic. These closures have continued to limit our ability to ship instruments and consumables to customer facilities and has limited their ability to prepare and ship samples to our VERI/O laboratory. In some geographies, especially at our global academic medical center customers’ sites, we saw a growing number of these operations returning to work, at least on a limited capacity,nine-month period primarily reflects an increase in the third quarter of 2020. In other areas, such as our large biopharmaceutical customers, the reopening process has been slower than anticipated as these customers remain cautious about reopening their facilities due to continued increases in COVID-19 infection rates. In addition, these customers are operating with limited resources in certain cases and are prioritizing other COVID-related programs in the near term, impacting our ability to resume non-COVID programs planned with these customers prior to the pandemic. While we cannot be certain of the ultimate impact the COVID-19 pandemic will have on our business and that of our customers, we anticipate the generation of our product and product-related services ~~revenue will resume in future periods as our and our customers’ operations are able to return to pre-COVID-19 levels.~~revenue.

Product and product-related services revenue increased by 48% to $2.5 million for the three months ended September 30, 2021, compared with $1.7 million for the three months ended September 30, 2020. Product and product-related services revenue increased by 11% to $6.0 million for the nine months ended September 30, 2021, compared with $5.4 million for the nine months ended September 30, 2020.

This increase primarily reflects additional instrument placements made during the period with biopharmaceutical companies and ~~product-related services revenue represented 96% and 91%~~academic medical centers when compared to the same period in the prior year, when most of our ~~total~~customers had closed their laboratories due to COVID-19. In addition, consumables product revenue for the three months ended September 30, 2021 included revenue recognized from the sale of HTG Transcriptome Panel consumables. Revenue from the sale of the HTG Transcriptome Panel represented 27% and 18% of our consumables revenue for the three and nine months ended September 30, ~~2020, respectively, compared with 80% and 79% of total revenue for the three and nine months ended September 30, 2019, respectively, and was comprised of the following:~~

Product revenue generated from the sale of our HTG EdgeSeq instruments and RUO and CE IVD assay kits decreased by 43% and 20% to $0.8 million and $2.7 million for the three and nine months ended September 30, 2020, respectively, compared with $1.5 million and $3.3 million for the three and nine months ended September 30, 2019,2021, respectively. Product revenue represented 47% and 45% of our total revenue for the three and nine months ended September 30, 2020, respectively, compared with 27% and 23% of our total revenue for the three and nine months ended September 30, 2019, respectively. The decrease in product revenue in 2020 compared with 2019 reflects our limited ability to ship instruments and consumables to our customers’ facilities due to their facility closures resulting from the COVID-19 pandemic. The decrease also reflects a slower than anticipated return to pre-COVID purchasing patterns. In addition to reflecting decreased revenue in other areas of our core business, the increase in product revenue as a percentage of total revenue reflects purchasing by our European customers, who historically have accessed our technology through instrument and consumables purchases and who generally began their return to work in the second and third quarters of 2020 to a greater extent than our domestic customer base. We continue to discuss future studies with both new and existing customers and expect demand for our products to continue to increase as our customers are able to return to pre-COVID operating levels.

~~Service~~Product-related services revenue, consisting of RUO sample processing using our HTG EdgeSeq instruments and consumables in our VERI/O laboratory and custom RUO assay design, ~~decreased 70% and 66%~~increased by 53% to $1.3 million for the three months ended September 30, 2021, compared with $0.9 million for the three months ended September 30, 2020, and decreased by approximately 1% to $2.7 million for the nine months ended September 30, 2021, compared with $2.8 million for the nine months ended September 30, 2020. Specifically, RUO sample processing revenue generated in our VERI/O laboratory increased by 111% to $1.3 million for the three months ended September 30, 2021, compared with $0.6 million for the three months ended September 30, 2020, and increased by 73% to $2.7 million for the nine months ended September 30, 2021, compared with $1.6 million for the same period in 2020. This increase in RUO sample processing services for the three and nine months ended September 30, ~~2020, respectively, compared with $2.8 million and $8.1 million for~~2021 was partially offset by the ~~three and nine months ended September 30, 2019, respectively. The~~ decrease in ~~service revenue for the three and nine months ended September 30, 2020 compared with the same periods in 2019, primarily reflects~~ ~~a reduction in~~custom RUO ~~sample processing revenue due to continued COVID-19-related delays in sample receipt for anticipated customer programs and high levels of subcontracted laboratory~~assay design services in ~~2019 which did not recur in 2020.

services programs have been entered into in 2020. Though we continue to seek potential, new customer collaborations, we currently do not anticipate significant revenue from collaborative development services programs in 2020.

Cost of product and product-related servicesrevenue includes costs incurred to generate product and product-related ~~and services-related costs.~~services revenue. Product-related costs include the aggregate costs incurred in manufacturing, delivering, installing and servicing instruments and consumables. The components of our product-related costs of revenue include consumables and lab supplies, subcomponent and servicing costs, manufacturing costs incurred internally (which include direct labor costs), and equipment and infrastructure expenses associated with the manufacturing and distribution of our products. Due to the fixed nature of certain of these expenses, such as overhead, equipment and infrastructure, those associated with ~~our~~a regulated industry and our expectations for further growth in customer demand, we expect our cost of product and product-related services revenue as a percentage to decrease over time as we increase product and product-related services revenue, further absorbing these fixed costs.

Cost of product and product-related services revenue increased by 5% to $1.0 million for the three months ended September 30, 2021, compared with $0.9 million for the three months ended September 30, 2020. Cost of product and product-related services revenue decreased by ~~68% and 61%~~7% to ~~$0.9 million and $2.9~~$2.7 million for the ~~three and~~ nine months ended September 30, ~~2020, respectively,~~2021, compared with $2.9 million ~~and $7.5 million~~ for the ~~three and~~ nine months ended September 30, ~~2019, respectively.~~2020. This ~~decreased cost is consistent with the~~ decrease in ~~product and product-related services revenue for the three and nine months ended September 30, 2020 compared with 2019.

Selling, general and administrative expenses consist primarily of personnel costs for our sales and marketing, regulatory, legal, executive management and finance and accounting functions. The expenses also include third-party professional and consulting fees incurred by these functions, promotional expenses and facility and overhead costs for our administrative offices. Selling, general and administrative expenses ~~increased~~decreased by 5%11% to $4.2 million for the three months ended September 30, ~~2020~~2021, compared with $4.8 million for the ~~same period in 2019~~three months ended September 30, 2020.

Research and development expenses represent amounts incurred to perform collaborative development services, costs to develop new proprietary panels and ~~corresponding assays~~technologies, and costs to continue ~~to develop~~improving and ~~improve~~expanding the utility of our HTG EdgeSeq technology. These expenses include payroll and related expenses, consulting expenses, laboratory supplies, facilities and equipment. Research and development costs are expensed as incurred. Research and development expenses increased by 22% to $1.5 million for the three months ended September 30, 2021, compared with $1.3 million for the three months ended September 30, 2020. This increase primarily reflects hiring, payroll-related costs and the initiation of feasibility studies associated with HTG Therapeutics in the third quarter of 2021. Research and development expenses decreased by ~~51%~~15% to $4.2 million for the nine months ended September 30, 2021, compared with $4.9 million for the nine months ended September 30, 2020. This decrease is primarily due to a reduction in research and ~~38%~~development headcount since the first quarter 2020 as a result of the completion of our existing collaborative development services programs in 2020 and the transitioning of our transcriptome concept project from our California research facility to ~~$1.3 million~~our Tucson development laboratory for completion of the development of the HTG Transcriptome Panel in the second half of 2020.

Cash Flows for the nine months ended September 30, ~~2020~~2021 and ~~2019~~2020

The following table summarizes the primary sources and uses of cash for each of the periods presented:

Net cash used in operating activities for the nine months ended September 30, 2021 was $13.1 million compared with net cash used in operating activities of $12.7 million for the nine months ended September 30, 2020. Net cash used in operating activities for the nine months ended September 30, 2021 reflected (i) a net loss of $12.0 million; (ii) net non-cash items consisting primarily of the gain on the forgiveness of our PPP loan of $1.7 million, stock-based compensation expense of $1.0 million, depreciation and amortization expense of $0.6 million, amortization of loan discount and issuance costs of $0.4 million, amortization of right-of-use assets of $0.4 million and loss on abandonment and disposal of assets of $0.2 million; and (iii) a net cash outflow from changes in balances of operating assets and liabilities of $2.0 million.

This activity for the nine months ended September 30, 2021 consisted primarily of $10.7 million in net proceeds from our ATM Offering and $0.6 million in proceeds from our stock purchase agreement (the “LP Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), partially offset by $0.4 million of payments made on our outstanding NuvoGen obligation, and $0.5 million of payments made on our 2020 and 2021 Insurance Notes.

Net cash provided by financing activities for the nine months ended September 30, 2020 was $7.3 million. This activity for the nine months ended September 30, 2020 consisted primarily of $6.4 million in net proceeds from our ATM Offering, $1.7 million in proceeds from our PPP Loan, and $0.6 million in net proceeds from our Series A convertible preferred stock private placement, partially offset by $0.6 million of net payments to extinguish our QNAH Convertible Note and MidCap Credit Facility obligations with cash on hand and proceeds from our SVB Term Loan, $0.5 million of payments made on our outstanding NuvoGen obligation, and $0.3 million of payments made on our Insurance Note.

Net cash provided by financing activities for the nine months ended September 30, 2019 was $20.1 million. This activity for the nine months ended September 30, 2019 consisted primarily of $20.8 million in net proceeds from our underwritten public offering and concurrent private placement in September 2019, offset by $1.0 million of payments made on our outstanding NuvoGen obligation.

Since our inception, our operations have primarily been financed through the issuance of our common stock, redeemable convertible preferred stock, the incurrence of debt and cash received from product sales, services revenue and other income. As of September 30, ~~2020,~~2021, we had ~~$30.5~~$25.4 million in cash, cash equivalents and investments in short-term available-for-sale securities, and ~~$17.3~~current liabilities of approximately $8.1 million. As of September 30, 2021, we also had approximately $11.5 million of long-term liabilities outstanding, relating to our SVB Term Loan (see below), our NuvoGen and ~~PPP Loan~~2021 Insurance Note obligations, and our financing and operating leases.

In September 2019, we completed an underwritten public offering in which we sold 29,298,537 shares of our common stock at a price of $0.65 per share, including 3,821,548 shares sold pursuant to the exercise in full of the underwriter’s option to purchase additional shares. The shares of common stock described above were offered pursuant to a Registration Statement on Form S-3 (File No. 333-229045) previously filed with the SEC and declared effective by the SEC on February 11, 2019, and a prospectus supplement thereafter. In addition, we concurrently entered into a securities purchase agreement with certain institutional accredited investors for the sale of 5,411,687 pre-funded warrants exercisable for an aggregate of 5,411,687 shares of common stock, at a purchase price of $0.64 per pre-funded warrant. The aggregate net proceeds from these offerings for the year ended December 31, 2019 were approximately $20.8 million, after deducting the underwriting discounts and commissions and offering expenses. Additional proceeds of $31,768 were received in the first quarter of 2020 as a result of the exercise of 3,176,762 of the pre-funded warrants.

In November 2019, we entered into a Controlled Equity Offering Sales Agreement (the “Cantor Sales Agreement”) with Cantor as sales agent, pursuant to which we ~~may~~were able to offer and sell, from time to time, through Cantor, shares of our common stock by any method deemed to be an “at the market offering” as defined by rule 415(a)(4) under the Securities Act (the “ATM Offering”). ~~The~~We have sold an aggregate of 3,961,335 shares ~~will be offered~~of our common stock in the ATM Offering between its inception and ~~sold~~September 30, 2021 for net proceeds of $18.2 million pursuant to our shelf registration statement on Form S-3 (File No. 333-229045). We have offered and sold 10,436,016 shares of our common stock under the ATM Offering through September 30, 2020 for net proceeds of $6.4 million. As of September 30, 2020, we are permitted to sell up to approximately $8.6 million of additional shares of our common stock under the current prospectus supplement for the ATM Offering.

In February 2020, we issued 41,100 shares of our Series A convertible preferred stock (“Series A Preferred”) to accredited investors, in exchange for the investors surrendering to us for cancellation an aggregate of ~~4,110,000~~274,000 shares of our common stock. In addition, we sold an aggregate of 10,170 additional shares of our Series A Preferred to the accredited investors for aggregate gross

proceeds of approximately ~~$600,000,~~$0.6 million, and transaction costs of approximately $37,000. Each share of Series A Preferred is convertible into ~~100~~6.67 shares of the Company’s common stock, subject to proportional adjustment and beneficial ownership limitations. In June 2020, the investors elected to convert 27,500 shares of Series A Preferred to common stock, resulting in the issuance of ~~2,750,000~~183,333 shares of the Company’s common stock. The remaining 23,770 ~~shares of~~ Series A Preferred shares remain outstanding as of September 30, ~~2020.~~2021. In the event of ~~our~~the Company’s liquidation, dissolution or winding up, holders of Series A Preferred will participate pari passu with any distribution of proceeds to holders of ~~our~~the Company’s common stock. Holders of Series A Preferred are entitled to receive dividends on shares of Series A Preferred equal (on an as converted to common stock basis) to and in the same form as dividends actually paid on ~~our~~the Company’s common stock. Shares of Series A Preferred generally have no voting rights, except as required by law.

In March 2020, we entered into ~~a purchase agreement ("~~the LP Purchase ~~Agreement") with Lincoln Park Capital Fund, LLC ("Lincoln Park")~~Agreement, pursuant to which, upon the terms and subject to the conditions and limitations set forth therein, we have the right to sell to Lincoln Park up to ~~$20,000,000~~$20.0 million of shares of our common stock (“Purchase Shares”) from time to time over the 36-month term of the LP Purchase Agreement. The purchase price of the Purchase Shares will be based on recent closing prices of our common stock at the time of sale. We issued Lincoln Park an aggregate of ~~615,384~~41,026 shares of our common stock as consideration for their purchase commitment pursuant to the LP Purchase Agreement.

In April 2020, we received the proceeds from the PPP Loan in the amount of ~~$1,717,000~~$1.7 million from SVB, as lender, pursuant to the Paycheck Protection Program of the ~~CARES Act. The PPP Loan matures on April 21, 2022~~Coronavirus Aid, Relief, and ~~bears interest at an annual rate of 1%~~Economic Security Act (the “CARES Act”). ~~Beginning on March 21,~~In May 2021, we ~~are required to make 14 equal monthly payments of principal and interest for all amounts~~received notification from SVB that ~~are not forgiven through the SBA’s application and documentation process. We may prepay~~ the PPP Loan ~~at any time prior to maturity with no prepayment penalties.~~and related accrued interest, totaling $1,735,792, was forgiven in full by the U.S. Small Business Administration, and the PPP Loan note was canceled.

OnIn June ~~24,~~ 2020, we entered into ~~the~~a Loan and Security Agreement (the “Loan Agreement”) for an asset-secured loan in the principal amount of $10.0 million with ~~SVB.~~Silicon Valley Bank (“SVB”), as lender (the “SVB Term Loan”). The proceeds from the SVB Term Loan were fully funded on the June 25, 2020. The proceeds from the SVB Term Loan, together with cash on hand, were used to repay in full all outstanding amounts and fees due under our MidCap Credit Facility and the QNAH Convertible Note. Our SVB Term Loan bears interest at a floating rate equal to the greater of 2.50% above the Prime Rate (as defined in the Loan and Security Agreement) and 5.75% and ~~requires~~originally required interest-only payments payable monthly in arrears through June 30, 2021. This interest-only period ~~may be~~has been extended for an additional six months ~~upon~~as a result of the Company’s achievement of anthe equity milestone defined in the Loan Agreement. The ~~ultimate~~extended interest-only period will be followed by equal monthly payments of principal and interest through the maturity date of December 1, 2023. In addition, we must comply with a financial covenant requiring that we maintain a certain amount of unrestricted cash under ~~our~~the Loan Agreement ~~with SVB~~ (see Note 8 to our condensed consolidated financial statements included elsewhere in this report). If sufficient additional capital is not available as and when needed, we may have to delay, scale back or discontinue one or more product development programs, curtail our commercial activities, significantly reduce expenses, sell assets (potentially at a discount to their fair value or carrying value), enter into relationships with third parties to develop or commercialize products or technologies that we otherwise would have sought to develop or commercialize independently, cease operational altogether, pursue a sale of the Company at a price that may result in a significant loss on investment for our stockholders, file for bankruptcy or seek other protection from creditors, or liquidate all assets. In addition, if we default under the Loan Agreement, SVB could accelerate the payment of the SVB Term Loan and ultimately foreclose on our assets.

We have had recurring operating losses and negative cash flows from operations since our inception and have an accumulated deficit of ~~$186.9~~$203.1 million as of September 30, ~~2020.~~2021. As of September 30, ~~2020,~~2021, we had cash, cash equivalents and investments in short-term available-for-sale securities of approximately ~~$30.5~~$25.4 million and ~~had~~ current liabilities of approximately ~~$6.0~~$8.1 million. As of September 30, ~~2020,~~2021, we also had ~~$14.5~~$11.5 million in long-term liabilities primarily attributable to ~~our~~the SVB Term Loan ~~PPP Loan~~ and our NuvoGen ~~obligations.~~obligation. We ~~believe~~cannot be certain that our existing resources will be sufficient to fund our planned operations and expenditures for at least the next 12 months from issuance of these condensed consolidated financial statements. ~~However, we cannot provide assurances that our plans will not change or that changed~~Potentially changing circumstances, especially those related to ~~the~~ COVID-19, ~~pandemic, will not~~may also result in the depletion of our capital resources more rapidly than we currently anticipate. These circumstances raise substantial doubt about our ability to continue as a going concern.

Until our revenue reaches a level sufficient to support self-sustaining cash flows, if ever, we ~~may~~will need to raise additional capital to fund our continued operations, including our product development and commercialization activities related to our current and future products. Future funding requirements will depend on a number of factors, including our ability to generate significant revenue, our

ability to repay our debt obligations as they become due, the cost and timing of establishing additional sales, marketing and distribution capabilities, the ongoing cost of research and development activities, the cost and timing of regulatory clearances and approvals, the effect of competing technology and market developments, the nature and timing of companion diagnostic development collaborations we may establish ~~and the successful commercialization of clinical diagnostic products developed and approved as a result of such collaborations~~ and the extent to which we acquire or invest in businesses, products and technologies.

Additional capital may not be available at such times or in amounts needed by us. Even if sufficient capital is available to us, it might be available only on unfavorable terms. If we are unable to raise additional capital in the future when required and insufficient amounts or on terms acceptable to us, we may have to delay, scale back or discontinue one or more product development programs, curtail our commercialization activities, significantly reduce expenses, sell assets (potentially at a discount to their fair value or carrying value), enter into relationships with third parties to develop or commercialize products or technologies that we otherwise would have sought to develop or commercialize independently, cease operations altogether, pursue an acquisition of our company at a price that may result in a significant loss on investment to our stockholders, file for bankruptcy, seek other protection from creditors, or liquidate all of our assets. In addition, if we default under our SVB Term Loan agreement, our lender could foreclose on our assets.

~~We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.~~

See Note 2. Summary of Significant Accounting Policies – Recently Adopted and Recently Issued Accounting Pronouncements in the notes to the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“~~U.S.~~ GAAP”). The preparation of financial statements in conformity with ~~U.S.~~ GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. ~~Items subject to~~Although these estimates are based on ~~judgments include, but are~~management’s best knowledge of current events and actions that may impact us in the future, the estimation process is, by its nature, uncertain given that estimates depend on events over which we may not ~~limited to: revenue recognition, stock-based compensation expense,~~have control. Though the ~~resolution~~impact of ~~uncertain tax positions, income tax valuation allowances, recovery~~COVID-19 on our business and operating results presents additional uncertainty, we continue to use the best information available to inform our critical accounting estimates. If market and other conditions change from those that we anticipate, our condensed consolidated financial statements may be materially affected. In addition, if our assumptions change, we may need to revise our estimates, or take other corrective actions, either of ~~long-lived assets~~which may also have a material effect on our condensed consolidated financial statements.

We believe that our critical accounting policies and ~~provisions for doubtful accounts, inventory obsolescence~~estimates have a higher degree of inherent uncertainty and ~~inventory valuation. Actual results~~require our most significant judgments. In addition, had we used estimates different from any of these, our condensed consolidated financial statements could have been materially ~~differ~~different from ~~these~~those presented. Members of our senior management have discussed the development and selection of our critical accounting policies and estimates, and ~~such differences could affect~~our disclosures regarding them, with the ~~results~~Audit Committee of ~~operations in future periods.~~

our Board of Directors. There were no changes in our critical accounting policies and estimates during the nine months ended September 30, ~~2020~~2021 from those set forth in “Critical Accounting Policies and Significant Judgments and Estimates” in our December 31, ~~2019~~2020 Annual Report on Form 10-K filed with the SEC on March 25, ~~2020 other than the adoption of the following new accounting pronouncements in the first quarter of 2020.~~2021.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement, which made a number of changes meant to add, modify or remove certain disclosure requirements associated with the movement against or hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. The standard was adopted on January 1, 2020 and did not have a material impact on the disclosures relating to our existing fair value measurements.

~~In November 2018, the FASB issued ASU No. 2018-18, which amended ASC 808,~~ ~~Collaborative Arrangements~~ ~~and ASC 606,~~ ~~Revenue from Contracts with Customers~~ (“ASU 2018-18”), to require that transactions in collaborative arrangements be accounted for under ASC 606 if the counterparty is a customer for a good or service (or bundle of goods and services) that is a distinct unit of account. The amendments also precluded entities from presenting consideration from transactions with a collaborator that is not a customer together with revenue recognized from contracts with customers. We adopted ASU 2018-18 on January 1, 2020. The adoption of ASU 2018-18 did not have an impact on our condensed consolidated financial statements as it did not change the way collaborative development services revenue and the related costs of these services are reflected in our condensed consolidated financial statements.

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported with the time periods specified

in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. In addition, the design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, control may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

As of September 30, ~~2020,~~2021, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this quarterly report, our disclosure controls and procedures were effective at the reasonable assurance level.

An evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of any change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. That evaluation did not identify any changes in our internal control over financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

We are not engaged in any material legal proceedings. However, in the normal course of business, we may from time to time be named as a party to legal claims, actions and complaints, including matters involving employment, intellectual property, vendors, customers or others.

Below is a summary of the principal factors that make an investment in our common stock speculative or risky. This summary does not address all of the risks that we face. Additional discussion of the risks summarized in this risk factor summary, and other risks that we face, can be found below under the heading “Risk Factors” and should be carefully considered, together with other information in this Quarterly Report on Form 10-Q and our other filings with the SEC before making investment decisions regarding our common stock.

An investment in shares of our common stock involves a high degree of risk. You should carefully consider the following risk factors, as well as the other information in this report, and in our other public filings, before deciding to purchase, hold or sell shares of our common stock. The occurrence of any of the following risks could have a material adverse effect on our business, financial condition, results of operations and future growth prospects or cause our actual results to differ materially from those contained in forward-looking statements we have made in this report and those we may make from time to time. In these circumstances, the market price of our common stock could decline, and you may lose all or part of your investment. You should consider all of the risk factors described when evaluating our business. We have marked with an asterisk (*) those risk factors that were not included as separate risk factors in, or reflect changes to, the similarly titled risk factors included inPart I, Item 1A, Risk Factors, in our Annual Report on Form 10-K, filed with the SEC on March 25, ~~2020.~~2021.

*We have incurred losses since our inception and expect to incur losses for the foreseeable future. We cannot be certain that we will achieve or sustain profitability.*

We have incurred losses since our inception and expect to incur losses in the future. We incurred net losses of $4.5 million and $12.0 million for the three and nine months ended September 30, 2021, respectively, compared with net losses of $5.4 million and $16.6 million for the three and nine months ended September 30, 2020, ~~respectively, compared with net losses of $4.7 million and $14.9 million for the three and nine months ended September 30, 2019,~~ respectively. As of September 30, ~~2020,~~2021, we had an accumulated deficit of ~~$186.9~~$203.1 million. We expect that our losses will continue for the foreseeable future as we will be required to invest significant additional funds to support product development, including development of new proprietary HTG EdgeSeq panels and products, ~~and~~ the commercialization of our HTG EdgeSeq ~~system~~platform and proprietary ~~consumables.~~consumables and advancement of our HTG Therapeutics business unit. We also expect that our selling, general and administrative expenses will continue to increase due to the additional costs associated with market development activities and expanding our staff to sell and support our products and services. Our ability to achieve or, if achieved, sustain profitability is based on numerous factors, many of which are beyond our control, including the market acceptance of our products and services, competitive product development and our market penetration and margins. We may never be able to generate sufficient revenue to achieve or, if achieved, sustain profitability.

*If we are unable to successfully commercialize our products, our business may be adversely affected.*

Our HTG Edge system was introduced for sale in the life sciences research market in the third quarter of 2013. Our HTG EdgeSeq chemistry was introduced for sale in the life sciences research market in the third quarter of 2014. Our dedicated HTG EdgeSeq ~~system~~platform was introduced for sale in the life sciences research market in the fourth quarter of 2015 and has been our primary product focus since 2016. Our VERI/O service laboratory was announced in June 2016. Our first diagnostic assay, based on our HTG EdgeSeq chemistry and automated inon our HTG EdgeSeq ~~system,~~platform, was introduced for sale in Europe in July 2016. We commercially launched our HTG Transcriptome Panel in August 2021. Although we believe that the HTG Transcriptome Panel will be a foundational product for RUO profiling, future companion diagnostics and potential proprietary diagnostic products and will allow us to further expand our product offerings outside of oncology and autoimmune and into additional markets such as transplant and diabetes, we have only recently initiated commercial sales of this panel and it may not have the commercial success that we anticipate or hope for, or that it will allow us to expand our product offerings. We currently market our products through our own sales force in the United States and Europe and have distributors in parts of ~~Europe and the Middle East.~~Europe. We intend to expand our sales and support teams in the United States and in Europe and to establish additional distributor and/or third-party contract sales team relationships in other parts of the world. However, we may not be able to market and sell our products effectively. Our sales of life science research products, profiling and diagnostic products, and potential future products will depend in large part on our ability to successfully increase the scope of our marketing efforts and establish and maintain a sales force commensurate with our then applicable markets. If we do not build and maintain an efficient and effective sales force and distributor relationships targeting these markets, our business and operating results will be adversely affected.

If our HTG EdgeSeq ~~system~~platform and proprietary profiling panels fail to achieve and sustain sufficient market acceptance, or we are not able to continue to expand our service or collaborative relationships with biopharmaceutical customers, either directly or through a collaboration partner, we will not generate expected revenue, and our prospects may be harmed.

We are currently focused on selling our HTG EdgeSeq ~~system~~platform and profiling panels within the life sciences research market and, where approved, in the diagnostic market. We plan to develop panels for many different disease states including companion diagnostics to determine the proper course of treatment for those diseases. We may experience reluctance, or refusal, on the part of physicians to order, and third-party payors to cover and provide adequate reimbursement for, our panels if the results of our research and clinical studies, and our sales and marketing activities relating to communication of these results, do not convey to physicians, third-party payors and patients that the HTG EdgeSeq ~~system~~platform and related profiling panels provide equivalent or better diagnostic information than other available technologies and methodologies. We believe our panels represent an emerging methodology in diagnosing disease states, and we may have to overcome resistance among physicians to adopting it for the marketing of our products to be successful. Even if we are able to obtain regulatory approval from the U.S. Food and Drug Administration (“FDA”) or other applicable regulatory authorities, the use of our panels may not become the standard diagnostic tool for those diseases on which we plan to focus our efforts.

In addition, a key component of our strategy is to develop diagnostic tools in conjunction with biopharmaceutical companies’ drug development programs, to help assess the proper course of treatment for specific diseases. Even if we are successful in developing those diagnostic tools and receive regulatory approval, we still may not be successful in marketing those diagnostic tests. Furthermore, the decision to advance an underlying drug candidate through clinical trials and ultimately to commercialization is at the discretion of biopharmaceutical companies with which we collaborate. Our biopharmaceutical partners may take certain actions that could negatively impact the utility and marketability of our diagnostic tests. For example, our biopharmaceutical partners could:

To the extent that we develop diagnostic assays for a biopharmaceutical company in collaboration with a collaboration partner, we may not have responsibility for some or all aspects of developing, marketing or commercializing any resulting diagnostic tests. In addition to this biopharmaceutical partner risk, a collaboration partner may take certain actions that could negatively impact the development, utility and marketability of the applicable diagnostic tests. For example, a collaboration partner could fail to satisfy or fall behind in its obligations to us or to the biopharmaceutical company for which we develop a companion diagnostic test, which may delay development, regulatory approvals, market development and/or commercialization of the applicable companion diagnostic test.

As a result of our termination of the Governing Agreement in November 2019, we no longer have a commercialization partner for the development, manufacture and commercialization of companion diagnostics for biopharmaceutical companies. Although the termination of the Governing Agreement does not preclude us from workingOur agreement with QML is non-exclusive and, in the future, either party may be unwilling to partner with the other, and we may be unable to ~~establish~~implement a feasible partnering relationship ~~with another suitable company~~ for the development, manufacture, marketing and/or commercialization of companion diagnostic assays on acceptable terms, or at all. If we are unable to ~~establish~~implement such a relationship, ~~with another company,~~ our efforts to develop, manufacture and commercialize companion diagnostic assays may be significantly delayed and limited in scale, or may not occur at all. ~~In addition, we do not know whether we will be able to enter into new collaborative arrangements with biopharmaceutical company customers on an independent basis.~~ Any of these events could limit our diagnostic test sales and ~~revenues~~revenue and have a material adverse effect on our business, operating results and financial condition.

~~Public health epidemics, pandemics~~We will need to raise additional capital to fund our operations in the future. If we are unsuccessful in attracting new capital, we may not be able to continue operations or ~~outbreaks,~~may be forced to sell assets to do so. Alternatively, capital may not be available to us on favorable terms, or if at all. If available, financing terms may lead to significant dilution of our stockholders’ equity.

We are not profitable and have had negative cash flow from operations since our inception. To fund our operations and develop and commercialize our products, we have relied primarily on equity and debt financings and revenue generated from the sale of our HTG EdgeSeq platform, proprietary consumables, related services and collaborative development service arrangements with biopharmaceutical company customers. We currently anticipate that our cash and cash equivalents may be sufficient to enable us to fund our operations for at least the next 12 months. However, we will need to obtain additional funds to finance our operations in the future, and we could spend our available financial resources much faster than we currently expect. These circumstances raise substantial doubt about our ability to continue as a going concern. Additional capital may not be available at such times or amounts as needed by us. Historically we have financed our business in part by access to the capital markets. General market conditions resulting from the ongoing issues arising from COVID-19, as well as market conditions affecting companies in the life sciences industry in general, may make it difficult for us to seek financing from the capital markets on attractive terms, or at all. Even if capital is available, it might be available only on unfavorable terms. Any additional equity or convertible debt financing into which we enter could be dilutive to our existing stockholders. Any future debt financing into which we enter may impose covenants upon us that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, we may need to relinquish rights to our technologies or our products or grant licenses on terms that are not favorable to us. If access to sufficient capital is not available as and when needed, our business will be materially impaired, and we may be required to cease operations, curtail one or more product development or commercialization programs, or significantly reduce expenses, sell assets, seek a merger or joint venture partner, file for protection from creditors or liquidate all of our assets. Any of these factors could harm our operating results.

*COVID-19 has adversely affected our business and is expected to have an impact on our business for the recent coronavirus pandemic, could adversely affect our business.*foreseeable future.

Our business, including our workforce, supply chain and customer base, ~~may be~~has been adversely affected by the effects of health epidemics, including the COVID-19 pandemic. As a result of health epidemics, including COVID-19, businesses may be shut down, supply chains can be interrupted, slowed, or rendered inoperable, and individuals can become ill, quarantined, or otherwise unable to work and/or travel due to health reasons or governmental restrictions.COVID‑19.

~~The~~ COVID-19 ~~pandemic~~ has caused several countries to implement quarantines and/or significant restrictions on travel. In addition, affected regions, including several states within the United States, have implemented work restrictions that prohibit many

employees from going to work. Moreover, ~~the~~ COVID-19 ~~pandemic~~ has resulted in business closures and a substantial reduction in economic activity in the United States and worldwide. The emergence of new variants of the SARS-CoV-2 virus raises the possibility that recurring cycles of restrictions will be imposed in the future, notwithstanding vaccination efforts.

While significant uncertainty remains as to the future impact of the COVID-19 pandemic on our operations, and on the global economy as a whole, ~~the~~ COVID-19 ~~pandemic has~~ had ~~and may continue to have,~~ a negative impact on our product and ~~product‑related~~product-related services revenue and collaborative development services revenue in ~~2020.~~2020. We experienced a significant slowing of ~~product and product-related services~~ revenue generation beginning in March 2020 as a result of ~~the~~ COVID-19, ~~pandemic,~~ and we believe this period of reduced revenue will continue ~~through at least the remainder of 2020~~into 2021 due to disruptions to our customers’ businesses as a result of the pandemic. The extent of this impact is likely to vary from customer to customer depending upon how they are directly or indirectly impacted by local stay-at-home orders and other social distancing measures, priorities for the customers when the immediate impacts of the pandemic have passed, and the workforce and supplier impacts that each customer has experienced during the pandemic.

~~Beginning the week of~~In March ~~16,~~ 2020, ~~substantially all~~most of our workforce began working from home either all or substantially all of the time. The effects of the stay-at-home orders and our work-from-home policies may negatively impact productivity, disrupt our business and delay our development programs and regulatory timelines and negatively impact our commercial activities, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. In addition, these widespread outbreaks of illness could adversely affect our workforce resulting in serious health issues and absenteeism.

It is also possible that ~~the~~ COVID-19 ~~pandemic~~ will ~~also~~continue to impact our workforce, supply chains or distribution networks or otherwise impact our ability to conduct sample processing services and custom assay design services and our ability to provide collaborative development services for companion diagnostic development programs. Governmental mandates may require forced shutdowns of our facilities for extended or indefinite periods. Pandemic outbreaks, including the ~~coronavirus,~~COVID-19, could also substantially interfere with general commercial activity related to our supply chain and customer base, which could have a material adverse effect on our financial condition, results of operations, business or prospects. Restrictions resulting from ~~the~~ COVID-19 ~~pandemic~~ may disrupt our supply chains or distribution networks or limit our ability to obtain sufficient materials for our consumables or instruments and may disrupt our ability to process customer samples or perform collaborative development services. Further, to the extent our customers’ businesses are adversely affected by the pandemic, they might delay or reduce purchases from us or collaborative development projects with us, which could adversely affect our results of operations.

The ultimate impact of ~~the~~ COVID-19 ~~pandemic~~ or a similar health epidemic is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our customers’ businesses, healthcare systems or the global economy as a whole. However, these effects could have a material adverse impact on our operations, financial position and liquidity.

*Our business operations might be disrupted or adversely affected by catastrophic events.

We manufacture our ~~consumable products and our~~ HTG EdgeSeq ~~system~~instrument and consumable products and perform our RUO profiling and collaborative development services in our Tucson, Arizona facilities. In addition, our Tucson facilities are the center for order processing, receipt of critical components of our HTG EdgeSeq instrument and shipping products to customers. We do not have redundant facilities. Damage or the inability to utilize our Tucson facilities and the equipment we use to perform research, development or services and manufacture our products could be costly, and we would require substantial lead-time to repair or replace this facility and equipment. The Tucson facilities may be harmed or rendered inoperable by natural or man-made disasters, including flooding, wind damage, power spikes and power outages, which may render it difficult or impossible for us to perform these critical functions for some period of time. The inability to manufacture consumables or instruments, process customer samples, perform development services or ship products to customers for even a short period of time may result in the loss of customers or harm our reputation, and we may be unable to regain those customers in the future. Although we possess insurance for damage to our property and the disruption of our business, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all. In addition, natural disasters or other catastrophic events in various parts of the world, including interruptions in the supply of natural resources, political and governmental changes, disruption in transportation networks or delivery services, severe weather conditions, wildfires and other fires, explosions, actions of animal rights activists, terrorist attacks, earthquakes, wars and public health issues could disrupt our operations or those of our collaborators, contractors and vendors or contribute to unfavorable economic or other conditions that could adversely impact us.

*Our financial results may vary significantly from quarter to quarter or may fall below the expectations of investors or securities analysts, each of which may adversely affect our stock price.*

Investors should consider our business and prospects considering the risks and difficulties we expect to encounter in the new, uncertain and rapidly evolving markets in which we compete. Because these markets are new and evolving, predicting their future growth and size is difficult. We expect that our visibility into future sales of our products, including volumes, prices and product mix between instruments, consumables and services, will continue to be limited and could result in unexpected fluctuations in our quarterly and annual operating results.

Numerous other factors, many of which are outside our control, may cause or contribute to significant fluctuations in our quarterly and annual operating results. For example, two customers accounted for ~~24%~~27% and ~~10%~~13% of our revenue for the three months ended September 30, ~~2020. In addition,~~2021, and two customers accounted for ~~30%~~52% and ~~13%~~11% of our accounts receivable balance as of September 30, ~~2020 and an additional two customers each accounted for 11% of our accounts receivable as of September 30, 2020.~~2021. If orders from our top customers are discontinued and we are unable to establish new ~~collaboration~~ projects ~~with biopharmaceutical companies,~~or continue to expand our customer base, our revenue in future periods may materially decrease. In addition, we experienced a significant slowing of product and product-related services revenue generation beginning in March 2020 as a result of ~~the COVID-19 pandemic, and we believe this~~COVID-19. This period of reduced revenue ~~will continue~~continued through ~~at least~~ the remainder of 2020 and continuing into 2021 due to disruptions to our customers’ businesses as a result of the pandemic. The extent of this impact on our ongoing business is likely to vary from customer to customer depending upon how they are directly or indirectly impacted by local stay-at-home orders and other social distancing measures, priorities for the customers when the immediate impacts of the pandemic have passed, and the workforce and supplier impacts that each customer has experienced during the pandemic. Fluctuations in our operating results may make financial planning and forecasting difficult. In addition, these fluctuations may result in unanticipated decreases in our available cash, which could negatively affect our business and prospects. Factors that may contribute to fluctuations in our operating results include many of the risks described under the caption “Risk Factors – Risks Related to Our Business and Strategy” of this report. In addition, one or more of such factors may cause our revenue or operating expenses in one period to be disproportionately higher or lower relative to the others. Our products involve a significant capital commitment from our customers or may depend on customer studies that have variable or indefinite timelines and accordingly, involve a lengthy sales cycle. We may expend significant effort in attempting to make a particular sale, which may be deferred by the

customer or never occur. Accordingly, comparing our operating results on a period-to-period basis may not be meaningful, and investors should not rely on our past results as an indication of our future performance. If such fluctuations occur or if our operating results deviate from our expectations or the expectations of investors or securities analysts, our stock price may be adversely affected.

*Our sales cycle is lengthy and variable, which makes it difficult for us to forecast revenue and other operating results.*

Our sales process involves numerous interactions with multiple individuals within any given organization, and often includes in-depth analysis by potential customers of our products (where in some instances we will provide a demonstration unit for their use and evaluation), performance of proof-of-principle studies, preparation of extensive documentation and a lengthy review process. As a result of these factors, the capital investment required in purchasing our instrument and the budget cycles of our customers, the time from initial contact with a customer to our receipt of a purchase order can vary significantly and be up to 12 months or longer. Given the length and uncertainty of our sales cycle, we have in the past experienced, and likely will in the future experience, fluctuations in our product and product-related services revenue on a period-to-period basis. In addition, any failure to meet customer expectations could result in customers choosing to retain their existing systems or service providers or to purchase systems or services other than ours. The revenue that we expect to earn from our collaborative development services are also subject to an extended, variable timeline based on each project agreement, which will likely result in fluctuations in our collaborative development services revenue on a period-to-period basis as well. Our collaborative development services revenue is also likely to continue to be impacted by ~~the ongoing~~ COVID‑~~19 pandemic.~~19.

We may not be able to develop new products or enhance the capabilities of our systems to keep pace with rapidly changing technology and customer requirements, which could have a material adverse effect on our business and operating results.

Our success depends on our ability to develop new products and applications for our technology in existing and new markets, while improving the performance and cost-effectiveness of our systems. New technologies, techniques or products could emerge that might offer better combinations of price and performance than our current or future products and systems. Existing or future markets for our products, including gene expression analysis, liquid-based specimen analysis (e.g., plasma, blood and urine) and single-cell analysis, as well as potential markets for our diagnostic product candidates, are characterized by rapid technological change and innovation. It is critical to our success that we anticipate changes in technology and customer requirements and successfully introduce new, enhanced and competitive technologies to meet our customers’ and prospective customers’ needs on a timely and cost-effective basis. At the same time, however, we must carefully manage the introduction of new products. If customers believe that such products will offer enhanced features or be sold for a more attractive price, they may delay purchases until such products are available. We may also have excess or obsolete inventory of older products as we transition to new products and our experience in managing product transitions is very limited. If we do not successfully innovate and introduce new technology into our product lines or effectively manage the transitions to new product offerings, our ~~revenues~~revenue and results of operations will be adversely impacted.

Competitors may respond more quickly and effectively than we do to new or changing opportunities, technologies, standards or customer requirements. We anticipate that we will face increased competition in the future as existing companies and competitors develop new or improved products and as new companies enter the market with new technologies.

If we do not successfully manage the development and launch of new products, our financial results could be adversely affected.

We face risks associated with launching new products and with undertaking to comply with regulatory requirements for certain types of our products (i.e., IVDs). If we encounter development or manufacturing challenges, adjust our product development priorities, or discover deficiencies during our product development cycle, the product launch date(s) may be delayed, or certain product development projects may be terminated. The expenses or losses associated with unsuccessful product development or launch activities or lack of market acceptance of our new products could adversely affect our business or financial condition.

*Our future success is dependent upon our ability to expand our customer base and introduce new applications.

Our current customer base is primarily composed of biopharmaceutical companies, ~~(including those contracted by QML pursuant to the Governing Agreement),~~ academic institutions and molecular labs that perform analyses using or directly or indirectly obtain services based on our HTG EdgeSeq ~~system~~platform and consumables for research use only, which means that the products or data from services may not be used for clinical diagnostic purposes. ~~In July 2016, we~~We have obtained CE ~~marking~~markings in Europe for our HTG EdgeSeq ~~system and~~consumables, including our HTG EdgeSeq DLBCL Cell of Origin Assay ~~EU. In March 2017, we obtained CE marking in Europe for~~EU and our HTG EdgeSeq ~~ALK~~AlkPlus ~~Assay~~ EU. These products may be used by customers for diagnostic purposes in Europe. With the EU transition to IVD Medical Device Regulation in May 2022, we would need to comply with these requirements in order to remain on the EU market other than research use only. Currently, we do not intend to and, where applicable, do not have appropriate licenses or permits to conduct diagnostic testing services. Our success will depend, in part, upon our ability to increase our market penetration among our customer bases and to expand our market by developing and marketing new companion diagnostic tests and RUO applications (whether product or service). We may not be able to successfully complete development of or commercialize any of our planned future tests and applications. To achieve these goals, we will need to conduct substantial research and development, conduct clinical

validation studies, expend significant funds, expand and scale-up our research, development, service and manufacturing processes and facilities, enter into service and collaborative development services arrangements with biopharmaceutical company customers, expand and train our sales force; and seek and obtain regulatory clearance or approvals of our new tests and applications, as required by applicable regulations. Additionally, we must demonstrate to laboratory directors, physicians and third-party payors that our current and any future diagnostic products are effective in obtaining clinically relevant information that can inform treatment decisions, and that our HTG EdgeSeq ~~system~~platform and related panels can enable an equivalent or superior approach than other available technology. Furthermore, we expect that a combination of increasing the installed base of our HTG EdgeSeq ~~systems~~instruments and entering into additional service and custom RUO assay design agreements with biopharmaceutical customers will drive increased demand for our relatively high margin panels. If we are not able to successfully increase our installed base and biopharmaceutical customer relationships,then sales of our products and services, and our margins for these revenue items may not meet expectations. Attracting new customers and introducing new products and services requires substantial time and expense. Any failure to expand our existing customer base, or launch new products, including diagnostic products or services, would adversely affect our ability to improve our operating results.

*The development of future products is dependent on new methods and/or technologies that we may not be successful in developing.

We ~~have initiated early development of a comprehensive whole transcriptome assay, which we are building for eventual clinical use and which~~commercially launched our HTG Transcriptome Panel in August 2021. Although we believe that the HTG Transcriptome Panel will ~~serve as our anchor~~be a foundational product ~~not only~~ for RUO profiling, ~~but also for our~~future companion diagnostics and potential proprietary ~~breast~~ diagnostic ~~products. In addition, we believe this product will serve as a universal CDx platform for gene expression profiling for our biopharmaceutical company customers. Moreover, we believe this product~~products, and will allow us to further expand our product offerings outside of oncology and autoimmune and into additional markets such as transplant and ~~diabetes. We cannot guarantee~~diabetes, we have only recently initiated commercial sales of this panel and it may not have the commercial success that we anticipate or hope for, or that it will allow us to expand our product offerings. In July 2021, we formed a new drug discovery business unit, HTG Therapeutics, which is expected to use our HTG Transcriptome Panel and an epitranscriptome profiling technology to profile RNA modifications, and we expect that, by leveraging these profiling technologies earlier in the drug discovery process, HTG Therapeutics will generate lead compounds faster, and with potentially more favorable efficacy and toxicity profiles. However, there can be no assurance that HTG Therapeutics will be able to ~~successfully develop~~accomplish these goals or will otherwise be successful. In addition, we are building a ~~comprehensive whole transcriptome assay or that it will have~~full machine learning-based chemical library design platform, which is expected to better predict the ~~benefits that we anticipate.~~ binding properties of a drug candidate to its target. If we are unsuccessful at developing this ~~assay~~ full machine learning-based chemical library design platform, or it, ~~does~~HTG Therapeutics or our HTG Transcriptome Panel do not provide the benefits that we anticipate, ~~we may be limited in the breadth of additional products we can offer in the future, which could impact~~ our future revenue ~~and profits.~~opportunities will be limited.

Our HTG EdgeSeq product portfolio requires the use of NGS instrumentation and reagents and could be adversely affected by actions of third-party NGS product manufacturers over whom we have no control.

A key element of our strategy is to establish our HTG EdgeSeq ~~system~~technology as the best sample and library preparation method for clinical applications of next-generation sequencers. We depend at least in part on the availability of NGS instrumentation and reagents, and the ability of our HTG EdgeSeq products to operate seamlessly with NGS instrumentation. Any significant interruption or delay in the ability of our HTG EdgeSeq products to operate on or with NGS instrumentation could reduce demand for our products and result in a loss of customers.

Our reputation, and our ability to continue to establish or develop our technology for clinical applications of next-generation sequencers, are dependent upon the availability of NGS instrumentation and the reliable performance of our products with NGS instrumentation. We are not able to control the providers of NGS instrumentation, which increases our vulnerability to interoperability problems with the products that they provide. For example, providers of NGS instruments may discontinue existing products, or

introduce new NGS instrumentation products with little or no notice to us. This may cause some of our products not to be operable with one or more NGS instruments or may adversely affect regulatory approvals of our future IVD HTG EdgeSeq products, potentially for extended periods of time. Any interruption in the ability of our products to operate on NGS instruments could harm our reputation or decrease market acceptance of our products, and our business, financial condition and operating results may be materially and adversely affected. We also could experience additional expense in developing new products or changes to existing products to meet developments in NGS instrumentation, including fees charged by our development partners to access new technology, and our business, financial condition and operating results may be materially and adversely affected.

Current medical device regulation in the United States and other jurisdictions requires manufacturers of IVD molecular profiling tests that use NGS detection, referred to as NGS IVD tests, to include in regulatory submissions, technical information about the NGS products that are required for performance of, but are not supplied with, the NGS IVD test. These regulatory agencies also require that the NGS instrumentation have “locked” software for the detection of the NGS IVD test results. Thus, to obtain regulatory approval for NGS IVD tests, manufacturers like us, currently must have arrangements with NGS product manufacturers to gain access to technical information and NGS instrument software. We currently have agreements with two NGS product manufacturers that grant us rights to develop, manufacture and sell future HTG EdgeSeq NGS IVD tests in specified fields, subject to, among other things, the NGS product manufacturers’ rights to terminate such agreements and discontinue products or implement product design changes that could adversely affect our HTG EdgeSeq NGS IVD tests. There can be no assurance that our agreements with these NGS product manufacturers, or any future NGS product manufacturers that we contract with, will not be terminated earlier than we currently expect, that a NGS product manufacturer will perform its contractual duties to us, or that we will otherwise receive the benefits we anticipate receiving under those agreements. In addition, if regulatory agencies do not change their requirements for NGS IVD test approval or clearance and the NGS instrument manufacturers close their systems to third-party NGS IVD test development (in general or with specific NGS IVD test manufacturers) and we are not able to maintain or enforce our agreements with such manufacturers, we may not be able to meet our commercial goals and our business, financial condition and operating results may be materially and adversely affected.

*If we do not achieve, sustain or successfully manage our anticipated growth, our business and growth prospects will be harmed.

Our current personnel, systems and facilities may not be adequate to support our business plan and future growth. Our need to effectively manage our operations, growth and various projects requires that we, among other things:

Moreover, growth will place significant strains on our management and our operational and financial systems and processes. For example, expanded market penetration of our HTG EdgeSeq ~~system~~platform and related proprietary panels, and future development and approval of diagnostic products, are key elements of our growth strategy that will require us to hire and retain additional sales and marketing, regulatory, manufacturing and quality assurance personnel. If we do not successfully forecast the timing and cost of the development of new panels and diagnostic products, the regulatory clearance or approval for product marketing of any future diagnostic products or the demand and commercialization costs of such products, or manage our anticipated expenses accordingly, our operating results will be harmed.

*If regulatory limitations are placed on our products our business and growth will be harmed.*

In many jurisdictions, including the United States, we are currently limited to marketing our HTG EdgeSeq ~~system~~platform and proprietary profiling panels for research use only, which means that we cannot make any diagnostic or clinical claims for those products in those jurisdictions.

We obtained the right to CE mark the HTG EdgeSeq DLBCL Cell of Origin Assay EU and the HTG EdgeSeq ALKPlus Assay EU for sale as IVDs in Europe, in July 2016 and March 2017, respectively. IfWith the EU transition to IVD Medical Device Regulation in May 2022, we ~~are unable~~would need to ~~maintain CE marking~~comply with these requirements in order to remain on the EU market other than research use only. While our current ex-U.S. strategy is to focus our efforts on the RUO market, in the event we want to expand our ex-U.S. business opportunities outside of research use only there would likely be additional clinical validations and certifications that we would need to obtain and there can be no assurance that we would be able obtain to obtain any such validations or ~~achieve appropriate ex-U.S. approvals on any of our products for their intended commercial uses~~certifications on a timely basis, or at ~~all, or~~all. In addition, if clinical diagnostic laboratories or other customers outside the United States do not accept our tests, our ability to grow our business outside of the United States could be compromised.

~~Clinical studies of any product candidate that we intend to market as an IVD kit may not be successful.~~ ~~If we are unable to successfully complete non-clinical and clinical studies of our product candidates or experience significant delays in doing so, our~~*Our HTG Therapeutics business will be materially harmed.*

Our clinical diagnostic business prospects in the United States and other applicable jurisdictions will depend on our ability to successfully complete clinical studies for product candidates that we intend to market as IVD kits. A failure of one or more clinical studies can occur at any stage of testing. The outcome of non-clinical studies may not be predictive of the success of clinical studies, and interim results, if any, of a clinical study do not necessarily predict final results. Moreover, non-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in non-clinical and clinical studies have nonetheless failed to obtain premarketing clearance or approval for their products. ~~Completion of clinical studies, announcement of results of the studies and our ability to obtain regulatory approvals could be delayed for a variety of reasons, including:~~

Our development costs will increase if we have material delays in any clinical study or if we need to perform more or larger clinical studies than planned. If the delays are significant, or if any of our products do not prove to be equivalent to a predicate device or safe or effective, as applicable, or do not receive required regulatory approvals, our financial results and the commercial prospects for our product candidates will be harmed. Furthermore, our inability to complete our clinical studies in a timely manner could jeopardize our ability to obtain regulatory approval.

~~Our~~ strategy ~~of developing companion diagnostic products~~ may require ~~large~~significant investments in working capital and may not generate any ~~revenues.~~revenue.

~~A key component~~In July 2021, we formed a new drug discovery business unit, HTG Therapeutics. This business unit is expected to use our HTG Transcriptome Panel and an epitranscriptome profiling technology evolved from our original HTG EdgeSeq technology, HTG

EpiEdgeSeq, to profile RNA modifications. By leveraging these profiling technologies earlier in the drug discovery process, our objective is for HTG Therapeutics to generate lead compounds faster, and with potentially more favorable efficacy and toxicity profiles, with the ultimate goal of ~~our strategy~~generating interest from pharmaceutical companies that results in research or licensing collaborations for, or acquisitions of, these compounds. However, we have no prior experience with drug discovery and development and may not be successful in this endeavor. Moreover, drug discovery and development is the development of companion diagnostic products designed to determine the appropriate patient population for administration of a particular therapeutic to more successfully treat a variety of illnesses. Prior to the termination of the Governing Agreementexpensive and will require investments in ~~November 2019, we had an exclusive arrangement with QML to develop certain companion diagnostic products for biopharmaceutical companies under the Governing Agreement. We~~working capital by us that may now choose to develop companion diagnostic products independently or with a collaboration partner. Successfully developing a companion diagnostic product depends both on regulatory approval for administration of the therapeutic, as well as regulatory approval of the associated diagnostic product.be significant. Even if we are successful in ~~developing products that would be useful as companion diagnostic products,~~partnering one or more early-stage drug discovery programs with a pharmaceutical company, we will need to expend potentially significant capital resources on these programs prior to any such partnering, and potentially ~~receive regulatory approval for such products, the biopharmaceutical companies~~after, and there can be no assurance that develop the corresponding therapeutics may ultimately be unsuccessful in obtaining regulatory approval for any such therapeutic, or, even if successful, select a competing technology to use in their regulatory submission instead of ours. The development, especially the independent development, of companion diagnostic products requires a significant investment of working capital, which may not result in any future income. This could require uswe will generate meaningful revenues from these programs. We will need to raise additional funds in order to finance the implementation of our HTG Therapeutics business strategy, which could dilute our current investors or could impact our ability to continue our operations in the future.

*We expect to generate a portion of our revenue internationally and are subject to various risks relating to our international activities, which could adversely affect our operating results.*

For the three and nine months ended September 30, ~~2020, 19%~~2021, approximately 24% and ~~31%~~30% of our revenue was generated from sales originated by customers located outside of the United States, respectively, compared with ~~29%~~19% and 31% for three and nine months ended September 30, ~~2019,~~2020, respectively. We expect that a percentage of our future revenue will continue to come from international sources, and we expect to expand our overseas operations and develop opportunities in additional areas. Engaging in international business involves a number of difficulties and risks, including:

As we expand internationally our results of operations and cash flows will become increasingly subject to fluctuations due to changes in foreign currency exchange rates. Historically, most of our revenue has been denominated in U.S. dollars, although we have sold our products and services in local currency outside of the United States, principally the Euro. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States. As our operations in countries outside of the United States grows, our results of operations and cash flows will increasingly be subject to fluctuations due to changes in foreign currency exchange rates, which could negatively impact our results of operations in the future. For example, if the value of the U.S. dollar increases relative to foreign currencies, in the absence of an offsetting change in local currency prices, our revenue could be adversely affected as we convert revenue from local currencies to U.S. dollars.

If we dedicate significant resources to our international operations and are unable to manage these risks effectively, our business, operating results and prospects will suffer. Moreover, we cannot be certain that the investment and additional resources required in establishing operations in other countries will produce desired levels of revenue or profitability.

In addition, any failure to comply with applicable legal and regulatory obligations could negatively impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of ~~shipments~~products and restrictions on certain business activities.

*If the utility of our HTG EdgeSeq ~~system,~~platform, proprietary profiling panels, services and solutions in development is not supported by studies published in peer-reviewed medical publications, the rate of adoption of our current and future products and the rate of reimbursement of our future products by third-party payors may be negatively affected.

We anticipate that we will need to maintain a continuing presence in peer-reviewed publications to promote adoption of our products by biopharmaceutical companies, academic institutions and molecular labs and to promote favorable coverage and reimbursement decisions. We believe that peer-reviewed journal articles that provide evidence of the utility of our current and future products or the technology underlying the HTG EdgeSeq ~~system,~~platform, consumables and services are important to our commercial success. It is critical to the success of our sales efforts that we educate a sufficient number of clinicians and administrators about our HTG EdgeSeq ~~system,~~technology, including our HTG EpiEdgeSeq technology, our current panels and services and our future solutions, and demonstrate the research and clinical benefits of these solutions. Our customers may not adopt our current and future solutions, and third-party payors may not cover or adequately reimburse our future products, unless they determine, based on published peer-reviewed journal articles and the experience of other researchers and clinicians, that our products provide accurate, reliable, useful and cost-effective information. Peer-reviewed publications regarding our products and solutions may be limited by many factors, including delays in the completion of, poor design of, or lack of compelling data from studies that would be the subject of the article. If our current and future product and product-related service solutions or the technology underlying such products and services do not receive sufficient favorable exposure in peer-reviewed publications, the rate of research and clinical adoption and positive coverage and reimbursement decisions could be negatively affected.

We may need to raise additional capital to fund our operations in the future. If we are unsuccessful in attracting new capital, we may not be able to continue operations or may be forced to sell assets to do so. Alternatively, capital may not be available to us on favorable terms, or if at all. If available, financing terms may lead to significant dilution of our stockholders’ equity.*

We are not profitable and have had negative cash flow from operations since our inception. To fund our operations and develop and commercialize our products, we have relied primarily on equity and debt financings and revenue generated from the sale of our HTG EdgeSeq systems, proprietary consumables, related services and collaborative development service arrangements with biopharmaceutical company customers (directly or indirectly via the Governing Agreement). We currently anticipate that our cash and cash equivalents will be sufficient to enable us to fund our operations for at least the next 12 months. We may need to obtain additional funds to finance our operations in the future if our estimates of the amount of cash necessary to fund our operations and development and commercialization activities prove to be wrong, and we could spend our available financial resources much faster than we currently expect. These circumstances raise substantial doubt about our ability to continue as a going concern. Additional capital may not be available at such times or amounts as needed by us. Historically we have financed our business in part by access to the capital markets. General market conditions resulting from the ongoing issues arising from the COVID-19 pandemic, as well as market conditions affecting companies in the life sciences industry in general, may make it difficult for us to seek financing from the capital markets on attractive terms, or at all. Even if capital is available, it might be available only on unfavorable terms. Any additional equity or convertible debt financing into which we enter could be dilutive to our existing stockholders. Any future debt financing into which we enter may impose covenants upon us that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, we may need to relinquish rights to our technologies or our products, or grant licenses on terms that are not favorable to us. If access to sufficient capital is not available as and when needed, our business will be materially impaired, and we may be required to cease operations, curtail one or more product development or commercialization programs, or significantly reduce expenses, sell assets, seek a merger or joint venture partner, file for protection from creditors or liquidate all of our assets. Any of these factors could harm our operating results.

We provide our HTG EdgeSeq ~~system~~instrument and profiling panels free of charge or through other arrangements to customers or key opinion leaders through evaluation agreements or reagent rental programs, and these programs may not be successful in generating recurring revenue from sales of our systems and proprietary panels.

We sell our HTG EdgeSeq ~~system~~instrument and profiling panels under different arrangements to expand our installed base and facilitate the adoption of our platform.

In some instances, we provide equipment free of charge under evaluation agreements for a limited period of time to permit the user to evaluate the system for their purposes in anticipation of a decision to purchase the system. We retain title to the equipment under such arrangements unless the evaluator purchases the equipment, and in most cases, require evaluation customers to purchase a minimum quantity of consumables during the evaluation period.

When we place a system under a reagent rental agreement, we install equipment in the customer’s facility without a fee and the customer agrees to purchase consumable products at a stated price over the term of the agreement. While some of these agreements did not historically contain a minimum purchase requirement, we have included a minimum purchase requirement in all current reagent rental agreements and will continue to do so in the future. We retain title to the equipment and such title is transferred to the customer at no additional charge at the end of the initial arrangement. The cost of the instrument under the agreement is expected to be recovered in the fees charged for consumables, to the extent sold, over the term of the agreement.

Other arrangements might include a research agreement whereby an academic collaborator agrees to provide biological samples in exchange for the use of an HTG EdgeSeq ~~system~~instrument at no cost in furtherance of the collaborator’s professional goals and/or the educational or research objectives of an applicable institution.

Any of the foregoing arrangements could result in lost ~~revenues~~revenue and profit and potentially harm our long-term goal of achieving profitable operations. In addition, we require customers who receive systems that we continue to own to carry insurance sufficient to protect us against any equipment losses, we cannot guarantee that they will maintain such coverage, which may expose us to a loss of the value of the equipment in the event of any loss or damage.

There are instances where we provide our systems to key opinion leaders free of charge, to gather data and publish the results of their research to assist our marketing efforts. We have no control over some of the work being performed by these key opinion leaders, or whether the results will be satisfactory. It is possible that the key opinion leader may generate data that is unsatisfactory and could potentially harm our marketing efforts. In addition, customers may from time to time create negative publicity about their experience with our systems, which could harm our reputation and negatively affect market perception and adoption of our platform.

Placing our HTG EdgeSeq ~~systems~~instruments under evaluation agreements, under reagent rental agreements or with our key opinion leaders without receiving payment for the instruments could require substantial additional working capital to provide additional units for sale to our customers.

We face risks related to handling of hazardous materials and other regulations governing environmental safety.

Our operations are subject to complex and stringent environmental, health, safety and other governmental laws and regulations that both public officials and private individuals may seek to enforce. Our activities that are subject to these regulations include, among other things, our use of hazardous materials and the generation, transportation and storage of waste. We could discover that we or an acquired business is not in material compliance with these regulations. Existing laws and regulations may also be revised or reinterpreted, or new laws and regulations may become applicable to us, whether retroactively or prospectively, that may have a negative effect on our business and results of operations. It is also impossible to eliminate completely the risk of accidental environmental contamination or injury to individuals. In such an event, we could be liable for any damages that result, and any liability could exceed our resources or any applicable insurance coverage we may have, which events could adversely affect our business.

The life sciences research and diagnostic markets are highly competitive. We face competition from enhanced or alternative technologies and products, which could render our products and/or technologies obsolete. If we fail to compete effectively, our business and operating results will suffer.

We face significant competition in the life sciences research and diagnostics markets. We currently compete with both established and ~~early stage~~early-stage life sciences research companies that design, manufacture and market instruments and consumables for gene expression analysis, liquid-based specimen analysis (e.g., plasma, blood and urine), single-cell analysis, PCR, digital PCR, other nucleic acid detection and additional applications. These companies use well-established laboratory techniques such as microarrays or qPCR as well as newer technologies such as next-generation sequencing. We believe our principal competitors in the life sciences research market are Agilent Technologies, Inc., ArcherDx, Inc., BioRad Laboratories, Fluidigm Corporation, Illumina, Inc., Abbott Molecular, Luminex Corporation, Affymetrix, Inc., NanoString Technologies, Inc., entities owned and controlled by QIAGEN N.V., Roche Diagnostics, a division of the Roche Group of companies, Personal Genome Diagnostics and Thermo Fisher Scientific, Inc. In addition, there are several other market entrants in the process of developing novel technologies for the life sciences market. One or more of our competitors could develop a product that is superior to a product we offer or intend to offer, or our technology and products may be rendered obsolete or uneconomical by advances in existing technologies.

Within the diagnostic market, there are competitors that manufacture systems for sales to hospitals and laboratories and other competitors that offer tests conducted through CLIA certified laboratories. We will also compete with commercial diagnostics companies. Most of our current competitors are either publicly traded, or are divisions of publicly traded companies, and enjoy a number of competitive advantages over us, including:

We believe that the principal competitive factors in all of our target markets include:

We believe that additional competitive factors specific to the diagnostics market include:

Our products may not compete favorably, and we may not be successful in the face of increasing competition from new products and technologies introduced by our existing competitors or new companies entering our markets. In addition, our competitors may have or may develop products or technologies that currently or in the future will enable them to produce competitive products with greater capabilities or at lower costs than ours. Any failure to compete effectively could materially and adversely affect our business, financial condition and operating results.

Our current business depends on levels of research and development spending by academic and governmental research institutions and biopharmaceutical companies, a reduction in which could limit demand for our products and adversely affect our business and operating results.

Our revenue is currently derived from sales of our HTG EdgeSeq ~~system~~instrument and related proprietary panels, the design of custom RUO assays and sample processing for research applications to biopharmaceutical companies, academic institutions and molecular labs, predominantly in the United States and Europe, and collaborative development services. The demand for our products and services will depend in part upon the research and development budgets of these customers, which are impacted by factors beyond our control, such as:

We believe that any uncertainty regarding the availability of research funding may adversely affect our operating results and may adversely affect sales to customers or potential customers that rely on government funding. In addition, academic, governmental and other research institutions that fund research and development activities may be subject to stringent budgetary constraints that could result in spending reductions, reduced allocations or budget cutbacks, which could jeopardize the ability of these customers to purchase our products or services. Our operating results may fluctuate substantially due to reductions and delays in research and development expenditures by these customers. Any decrease in our customers’ budgets or expenditures, or in the size, scope or frequency of capital or operating expenditures, could materially and adversely affect our business, operating results and financial condition.

*As part of our current business model, we intend to seek to enter into strategic development collaborations and licensing arrangements with third ~~parties to develop diagnostic tests.~~parties.

We have relied, and expect to continue to rely, on strategic development collaborations and licensing agreements with third parties to develop or in-license technologies based on which products or services we may develop or offer. We have entered into agreements with third parties to facilitate or enable our development of assays, and ultimately diagnostic tests, to aid in the diagnosis of oncology diseases, such as breast cancer and melanoma, and other diseases. We intend to enter into additional similar agreements with life sciences companies, biopharmaceutical companies and other researchers for future diagnostic products. In addition, we intend to enter into early-stage drug discovery and development collaborations. However, we cannot guarantee that we will enter into any additional ~~agreements. In particular,~~agreements or collaborations. For example, our life sciences research or biopharmaceutical customers are not obligated to collaborate with us or license technology to us, and they may choose to develop diagnostic products themselves or collaborate with our competitors. Establishing development collaborations and licensing arrangements is difficult and time-consuming. Discussions may not lead to development collaborations or licenses on favorable terms, or at all. Potential collaborators or licensors may elect not to work with us based upon their assessment of our financial, regulatory or intellectual property position. To the extent that we enter new collaborative development or licensing agreements, they may never result in the successful development or commercialization of

future tests or other products for a variety of reasons, including because our collaborators may not succeed in performing their obligations or may choose not to cooperate with us. We cannot control the amount and timing of our collaborators’

resources that will be devoted to performing their responsibilities under our agreements with them. Moreover, to the extent we agree to work exclusively with a party in a given area, our opportunities to collaborate with others would be limited. Even if we establish new relationships, they may never result in the successful development or commercialization of future tests or other products. Disputes with our collaborators could also impair our reputation or result in development delays, decreased ~~revenues~~revenue and litigation expenses.

Our research and development efforts will be hindered if we are not able to contract with third parties for access to archival patient samples.

Our future development of products for clinical indications will require access to archival patient samples for which data relevant to the clinical indication of interest is known. We rely on our ability to secure access to these archived patient samples, including FFPE tissue, plasma, serum, whole blood preserved in PAXgene, or various cytology preparations, together with the information pertaining to the clinical outcomes of the patients from which the samples were taken. Owners or custodians of relevant samples may be difficult to identify and/or identified samples may be of poor quality or limited in number or amount. Additionally, others compete with us for access to these samples for both research and commercial purposes. Even when an appropriate cohort of samples is identified, the process of negotiating access to these samples can be lengthy because it typically involves numerous parties and approval levels to resolve complex issues such as usage rights, institutional review board approval, privacy rights, publication rights, and intellectual property ownership. In addition, in some instances the cost to acquire samples can be prohibitively expensive. If we are not able to negotiate access to archived patient samples on a timely basis and on acceptable terms, or at all, or if our competitors or others secure access to these samples before us, our ability to research, develop and commercialize future products will be limited or delayed.

We are dependent on a single third-party supplier for a certain subcomponent of our systems and the loss of this supplier could harm our business.*

We currently rely on a single supplier to produce a subcomponent used in our HTG EdgeSeq ~~processors.~~instruments. While we periodically forecast our needs for this subcomponent, our contract with this supplier, which may be a standard purchase order, does not commit them to carry inventory or make available any particular quantities, and the supplier may give other customers’ needs higher priority than ours and we may not be able to obtain adequate supplies in a timely manner or on commercially reasonable terms. If we were to lose this supplier, we may not be able to identify or enter into agreements with alternative suppliers on a timely basis on acceptable terms, or at all. If we should encounter delays or difficulties in securing the quality and quantity of subcomponent we require for our ~~processors,~~instruments, our supply chain would be interrupted which would adversely affect our sales. A loss of this supplier could significantly delay the delivery of our HTG EdgeSeq ~~processor,~~instruments, which in turn would materially affect our ability to generate revenue. If any of these events occur, our business and operating results could be materially harmed.

We may encounter manufacturing difficulties that could impede or delay production of our HTG EdgeSeq ~~systems.~~platform.

We began manufacturing our HTG EdgeSeq ~~system~~platform internally in 2016. We have limited experience with manufacturing the system and our internal manufacturing operations may encounter difficulties involving, among other things, scale-up of manufacturing processes, production efficiency and output, regulatory compliance, quality control and quality assurance, and shortages of qualified personnel. Any failure in our planned internal manufacturing operations could cause us to be unable to meet demand for these systems, delay the delivery of the system to customers, and harm our business relationships and reputation.

If we encounter difficulties in our planned internal manufacturing operations, we may need to engage a third-party supplier, provided we cannot be sure we will be able to do so in a timely manner, or at all, or on favorable terms.

Any of these factors could cause us to delay or suspend production of our HTG EdgeSeq ~~system,~~platform, entail unplanned additional costs and materially harm our business, results of operations and financial condition.

We rely on distributors for sales of our products in several markets outside of the United States.*

We have established exclusive and non-exclusive distribution agreements for our HTG EdgeSeq ~~system~~platform and related profiling panels within parts of Europe and the Middle East. We intend to continue to grow our business internationally, and to do so, in addition to expanding our own direct sales and support team, we plan to attract additional distributors and sales partners to maximize the commercial opportunity for our products. We cannot guarantee that we will be successful in attracting desirable distribution and sales partners or that we will be able to enter into such arrangements on favorable terms. Distributors and sales partners may not commit the necessary resources to market and sell our products to the level of our expectations or may favor marketing the products of our competitors. If current or future distributors or sales partners do not perform adequately, or we are unable to enter into effective arrangements with distributors or sales partners in particular geographic areas, we may not realize long-term international revenue growth.

*Clinical studies of any product candidate that we intend to market as an IVD kit may not be successful. If we are unable to successfully complete non-clinical and clinical studies of our product candidates or experience significant delays in doing so, we will not be able to expand our IVD kit offerings.

Our clinical diagnostic business prospects in the United States and other applicable jurisdictions will depend on our ability to successfully complete clinical studies for product candidates that we intend to market as IVD kits. A failure of one or more clinical studies can occur at any stage of testing. The outcome of non-clinical studies may not be predictive of the success of clinical studies, and interim results, if any, of a clinical study do not necessarily predict final results. Moreover, non-clinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in non-clinical and clinical studies have nonetheless failed to obtain premarketing clearance or approval for their products. Completion of clinical studies, announcement of results of the studies and our ability to obtain regulatory approvals could be delayed for a variety of reasons, including:

*Developing companion diagnostic products may require large investments in working capital and may not generate any revenue.

A component of our strategy is the development of companion diagnostic products designed to determine the appropriate patient population for administration of a particular therapeutic to more successfully treat a variety of illnesses. We may now choose to develop companion diagnostic products independently or with a collaboration partner. Successfully developing a companion diagnostic product depends both on regulatory approval for administration of the therapeutic, as well as regulatory approval of the associated diagnostic product. Even if we are successful in developing products that would be useful as companion diagnostic products, and potentially receive regulatory approval for such products, the biopharmaceutical companies that develop the corresponding therapeutics may ultimately be unsuccessful in obtaining regulatory approval for any such therapeutic, or, even if successful, select a competing technology to use in their regulatory submission instead of ours. The development, especially the

independent development, of companion diagnostic products requires a significant investment of working capital, which may not result in any future income. This could require us to raise additional funds which could dilute our current investors or could impact our ability to continue our operations in the future.

Limitations in the use of our products could harm our reputation or decrease market acceptance of our products; undetected errors or defects in our products could harm our reputation, decrease market acceptance of our products or expose us to product liability claims.

Our products are subject to the limitations set forth in the product labeling, which may not satisfy the needs of all customers. For example, in the past we have introduced new panels that initially were intended to be used with specific sample types. Because our customers desire that our panels be broadly applicable to many biological sample types, these initial limitations could harm our reputation or decrease market acceptance of our products. If that occurs, we may incur significant costs, the attention of our key personnel could be diverted, or other significant customer relations problems may arise, which could harm our business and operating results.

Similarly, our products may contain undetected errors or defects when first introduced or as new versions are released. Since our current customers use our products for research and, if cleared or approved for diagnostic applications, disruptions or other performance problems with our products may damage our customers’ businesses and could harm our reputation. If that occurs, we may incur significant costs, the attention of our key personnel could be diverted, or other significant customer relations problems may arise. We may also be subject to warranty and liability claims for damages related to errors or defects in our products. A material liability claim or other occurrence that harms our reputation or decreases market acceptance of our products could harm our business and operating results.

The sale and use of products or services based on our technologies, or activities related to our research and clinical studies, could lead to the filing of product liability claims if someone were to allege that one of our products contained a design or manufacturing defect which resulted in the failure to adequately perform the analysis for which it was designed. A product liability claim could result in substantial damages and be costly and time consuming to defend, either of which could materially harm our business or financial condition. We cannot assure investors that our product liability insurance could adequately protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing insurance coverage in the future.

*Payments under the instruments governing our indebtedness may reduce our working capital. In addition, a default under our ~~Silicon Valley Bank~~SVB Term Loan ~~or cross default under our PPP loan~~ could cause a material adverse effect on our financial position.*

Pursuant to the terms of ~~an asset purchase agreement with~~the NuvoGen obligation, we ~~agreed~~have paid NuvoGen $10.5 million, and are required to annually pay NuvoGen the greater of $400,000 or 6% of our yearly revenue until the total aggregate cash compensation paid to NuvoGen under the agreement equals $15.0 ~~million. To date, we have paid NuvoGen approximately $10.0~~ million. Payments to NuvoGen will result in a reduction in our working capital as we continue to make payments on this obligation.

The SVB Term Loan requires us, and any debt arrangements we may enter into in the future may require us, to comply with various covenants that limit our ability to, among other things:

These restrictions could inhibit our ability to pursue our business strategies. If we default under our obligations under the SVB Term Loan, the lender could proceed against the collateral granted to them to secure our indebtedness or declare all obligation under the SVB Term Loan to be due and payable. In certain circumstances, procedures by the lender could result in a loss by us of all of our equipment and inventory, which are included in the collateral granted to the lender. Our intellectual property is not included in the collateral granted to the lender but is subject to a negative pledge. In addition, upon any distribution of assets pursuant to any liquidation, insolvency, dissolution, reorganization or similar proceeding, the holders of secured indebtedness will be entitled to receive payment in full from the proceeds of the collateral securing our secured indebtedness before the holders of other indebtedness or our common stock will be entitled to receive any distribution with respect thereto.

~~Pursuant to the terms of our PPP Loan, we are required to make 14 equal monthly payments of principal and interest of any~~

amounts that are not forgiven. All or a portion of the PPP Loan may be forgiven by the SBA upon its acceptance of our application and documentation of expenditures in accordance with the SBA requirements. Under the CARES Act and PPP Flexibility Act, loan forgiveness is available for the sum of documented payroll costs, covered rent payments and covered utilities during the 24-week period beginning on the date of loan approval at the borrower’s option. Not more than 40% of the forgiven amount may be for non-payroll costs. The amount of the PPP Loan eligible to be forgiven will be reduced if our full-time headcount declines, or if salaries and wages for employees with salaries of $100,000 or less annually are reduced by more than 25% during the measurement period, unless certain safe harbors are met. We will be required to repay any portion of the outstanding principal and interest that is not forgiven, along with accrued interest, in accordance with the amortization schedule described above, and we cannot provide any assurance that we will be eligible for loan forgiveness or that any amount of the PPP Loan will ultimately be forgiven by the SBA.

In order to apply for the PPP Loan, we were required to certify that, among other things, the current economic uncertainty made the PPP Loan request necessary to support our ongoing operations. While we made this certification in good faith after analyzing, among other things, our financial situation and access to alternative forms of capital, and believe that we satisfied all eligibility criteria for the PPP Loan, and that our receipt of the PPP Loan is consistent with the broad objectives of the Paycheck Protection Program of the CARES Act, the certification described above does not contain any objective criteria and is subject to interpretation. In addition, the SBA has issued guidance stating that it is unlikely that a public company with substantial market value and access to capital markets will be able to make the required certification in good faith. The lack of clarity regarding loan eligibility under the Paycheck Protection Program has resulted in significant media coverage and controversy with respect to public companies applying for and receiving loans. In addition, PPP loans under the CARES Act may be subject to certain rules, regulations and Standard Operating Procedures (“SOPs”) applicable to the SBA’s Section 7(a) Loan Program, which includes PPP loans under the CARES Act. The interpretation and applicability of these rules, regulations and SOPs is unclear, as some of them have not been referenced in the CARES Act itself or in the guidance and interpretations issued by the SBA to date. If, despite our good-faith belief that we satisfied all eligible requirements for the PPP Loan, we are found to be in violation of any of the laws or governmental regulations that apply to us in connection with the PPP Loan, including the False Claims Act, or it is otherwise determined that we were not eligible to receive the PPP Loan, or it is determined that the Company has not adequately complied with the rules, regulations and SOPs applicable to the SBA’s Section 7(a) Loan Program, we may be subject to penalties, including significant civil, criminal and administrative penalties and could be required to repay the PPP Loan in its entirety, which would have an impact on our liquidity. In addition, our receipt of the PPP Loan may result in adverse publicity and damage to our reputation, and a review or audit by the SBA or other government entity or claims under the False Claims Act could consume significant financial and management resources. Any of these events could have a material advers~~e effect on our business, results of operations and financial condition.~~

*Changes in ~~tax~~ laws or regulations that are applied adversely to us or our customers may have a material adverse effect on our business, cash flow, financial condition or results of operations.*

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, the legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act (the “Tax Act”), enacted many significant changes to the U.S. tax laws. Future guidance from the Internal Revenue Service and other tax authorities with respect to the Tax Act may affect us, and certain aspects of the Tax Act could be repealed or modified in future legislation. For example, the CARES Act modified certain tax provisions of the Tax Act. In addition, it is uncertain if and to what extent various states will conform to ~~the Tax Act, the CARES Act or~~ any newly enacted federal tax legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under the Tax Act or future reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

*Our ability to use net operating loss carryforwards and certain other tax ~~attributed~~attributes may be limited.*

As of December 31, ~~2019,~~2020, we had federal net operating loss carryforwards (“NOLs”) to offset future taxable income of ~~$158.2~~ $177.6 million, of which $121.8 million will begin to expire after 2021 if not utilized, while the remainder can be carried forward indefinitely. A lack of future taxable income would adversely affect our ability to utilize these NOLs. Under the Tax Act, as modified by the CARES Act, our federal NOLs incurred in tax years beginning after December 31, 2017 may be carried forward indefinitely but the deductibility of these federal NOLs in tax years beginning after December 31, 2020 is limited to 80% of taxable ~~income, unless utilized in 2018, 2019, or 2020, in which case use of the NOLs is not limited. It is uncertain if and to what extent various states will conform to the Tax Act or the CARES Act.~~income. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “IRC”), and corresponding provisions of state law, a corporation that undergoes an “ownership change” (generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period) is subject to limitations on its ability to utilize its pre-ownership change NOL carryforwards and certain other pre-ownership change tax attributes to offset post-ownership change income or taxes. We believe we may have already experienced one or more ownership changes and may in the future experience one or more additional ownership changes, and thus, our ability to utilize pre-ownership change NOL carryforwards and other pre-ownership change tax attributes to offset post-ownership change income or taxes may be limited. Such limitations may cause a portion of our NOL and credit carryforwards to expire before we are able to utilize them. In addition, at the state level, there may be periods during which the use of NOL carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. We have recorded a full valuation allowance related to our NOLs and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets.

Acquisitions or joint ventures could disrupt our business, cause dilution to our stockholders and otherwise harm our business.

We may acquire other businesses, products or technologies as well as pursue strategic alliances, joint ventures, technology licenses or investments in complementary businesses. We have limited experience with respect to business, product or technology acquisitions or the formation of collaborations, strategic alliances and joint ventures or investing in complementary businesses. Any of these transactions could be material to our financial condition and operating results and expose us to many risks, including:

Foreign acquisitions involve unique risks in addition to those mentioned above, including those related to integration of operations across different cultures and languages, currency risks and the particular economic, political and regulatory risks associated with specific countries. Also, the anticipated benefit of any acquisition may not materialize. Future acquisitions or dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or amortization expenses or write-offs of goodwill, any of which could harm our financial condition. We cannot predict the number, timing or size of future joint ventures or acquisitions, or the effect that any such transactions might have on our operating results.

If any members of our management team were to leave us or we are unable to recruit, train and retain key personnel, we may not achieve our goals.

Our future success depends on our ability to recruit, train, retain and motivate key personnel, including our senior management, research and development, manufacturing, service and sales and marketing personnel. If we were to lose one or more of our key employees, we may experience difficulties in competing effectively, developing our technologies and implementing our business strategies. Competition for qualified personnel is intense, and we may not be able to attract talent. Our growth depends, in part, on attracting, retaining and motivating highly trained sales personnel with the necessary scientific background and ability to understand our systems at a technical level to effectively identify and sell to potential new customers, including new biopharmaceutical company customers. In particular, the commercialization of our HTG EdgeSeq ~~system~~platform and related panels requires us to continue to establish and maintain sales and support teams to optimize the markets for research tools and, where approved, diagnostic assays, and to fully optimize a broad array of diagnostic market opportunities as we receive approval for any future diagnostic products. We do not maintain fixed term employment contracts or key man life insurance relating to any of our employees. Because of the complex and technical nature of our products and the dynamic market in which we compete, any failure to retain our management team or to attract, train, retain and motivate other qualified personnel could materially harm our operating results and growth prospects.

Our operating results may be harmed if we are required to collect sales, services or other related taxes for our products and services in jurisdictions where we have not historically done so.

We do not believe that we are required to collect sales, use, services or other similar taxes from our customers in certain jurisdictions. However, one or more countries or states may seek to impose sales, use, services, or other tax collection obligations on us, including for past sales. A successful assertion by one or more jurisdictions that we should collect sales or other taxes on the sale of our products and services could result in substantial tax liabilities for past sales and decrease our ability to compete for future sales. Each country and each state has different rules and regulations governing sales and use taxes and these rules and regulations are subject to varying interpretations that may change over time. We review these rules and regulations periodically and, when we believe sales and use taxes apply in a particular jurisdiction, voluntarily engage tax authorities in order to determine how to comply with their rules and regulations. WeHowever, we cannot ~~assure you~~guarantee that we will not be subject to sales and use taxes or related penalties for past sales in jurisdictions where we presently believe sales and use taxes are not due.

Providers of goods or services are typically held responsible by taxing authorities for the collection and payment of any applicable sales and similar taxes. If one or more taxing authorities determines that taxes should have, but have not, been paid with respect to our products and services, we may be liable for past taxes in addition to being required to collect sales or similar taxes in respect of our products and services going forward. Liability for past taxes may also include substantial interest and penalty charges. Our customer contracts provide that our customers must pay all applicable sales and similar taxes. Nevertheless, customers may be reluctant to pay back taxes and may refuse responsibility for interest or penalties associated with those taxes or we may determine that it would not be feasible to seek reimbursement. If we are required to collect and pay back taxes and the associated interest and penalties and if our customers do not reimburse us for all or a portion of these amounts, we will have incurred unplanned expenses that may be substantial. Moreover, imposition of such taxes on our products and services going forward will effectively increase the cost of such products and services to our customers.

Many states are also pursuing legislative expansion of the scope of goods and services that are subject to sales and similar taxes as well as the circumstances in which a vendor of goods and services must collect such taxes. Following the U.S. Supreme Court decision in South Dakota v. Wayfair, Inc., states are now free to levy taxes on sales of goods and services based on an “economic nexus,” regardless of whether the seller has a physical presence in the state. Furthermore, legislative proposals have been introduced in Congress that would provide states with additional authority to impose such taxes. Accordingly, it is possible that either federal or state legislative changes may require us to collect additional sales and similar taxes from our customers in the future.

Our insurance policies are expensive and protect us only from some business risks, which may leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability, foreign liability, employee benefits liability, property, automobile, umbrella, workers’ compensation, crime (including cybercrime), fiduciary, products liability, pollution, errors and omissions and directors’ and officers’ insurance. We do not know, however, if we will be able to maintain existing insurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

Performance issues, service interruptions or price increases by our shipping carriers could adversely affect our business and harm our reputation and ability to provide our services on a timely basis.

Expedited, reliable shipping is essential to our operations. We rely heavily on providers of transport services for reliable and secure point-to-point transport of our HTG EdgeSeq ~~systems~~instrument and consumables to our customers and, as applicable, customers’ samples to our laboratory, and for enhanced tracking of these shipments. Should a carrier encounter delivery performance issues such as loss, damage or destruction of any instrumentation, consumables or samples, it would be costly to replace such instrumentation or consumables in a timely manner and may be difficult to replace customers’ samples lost or damaged in shipping, and such occurrences may damage our reputation and lead to decreased demand for our products and increased cost and expense to our business. In addition, any significant increase in shipping rates could adversely affect our operating margins and results of operations. Similarly, strikes, severe weather, natural disasters or other service interruptions affecting delivery services we use would adversely affect our ability to process orders for our products or receive recipient samples on a timely basis.

Changes in funding for the FDA, the SEC and other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs or diagnostic products to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

*The withdrawal of the United Kingdom from the European Union, commonly referred to as “Brexit,” may adversely impact our ability to obtain regulatory approvals of our product candidates in the United Kingdom and the European Union, result in restrictions or imposition of taxes and duties for importing our product candidates into the United Kingdom or the European Union, and may require us to incur additional expenses in order to develop, manufacture and commercialize our product candidates in the United Kingdom and the European Union.

Following the result of a referendum in 2016, the United Kingdom left the European Union on January 31, 2020, commonly referred to as ~~Brexit.~~“Brexit.” Pursuant to the formal withdrawal arrangements agreed between the United Kingdom and the European Union, the United Kingdom ~~will be~~was subject to a transition period ~~until~~that ended December 31, 2020, or the Transition Period, during which EU rules ~~will continue~~continued to apply. ~~Negotiations between~~A trade and cooperation agreement, or the ~~United Kingdom~~Trade and Cooperation Agreement, that outlines the ~~European Union are expected to continue in relation to the customs and~~future trading relationship between the United Kingdom and the European Union ~~following the expiry of the Transition Period.~~was agreed in December 2020.

Since a significant proportion of the regulatory framework in the United Kingdom applicable to our business and our product candidates is derived from EU directives and regulations, Brexit ~~following the Transition Period, could materially~~has had, and may continue to have, a material impact on the regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product candidates in the United Kingdom or the European Union. For example, ~~as a result of the uncertainty surrounding Brexit, the EMA relocated to Amsterdam from London. Following the Transition Period, the United Kingdom will~~Great Britain is no longer be covered by the centralized procedures for obtaining EU-wide marketing authorization from the EMA and, ~~unless a specific agreement is entered into,~~and a separate ~~process for~~marketing authorization ~~of drug products, including our product candidates,~~ will be required ~~in the United Kingdom, the potential process for which is currently unclear. Any delay in obtaining, or an inability~~ to ~~obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from commercializing~~marker our product candidates in Great Britain. It is currently unclear whether the ~~United Kingdom~~Medicines & Healthcare products Regulatory

Agency, or MHRA, in the ~~European Union~~U.K. is sufficiently prepared to handle the increased volume of marketing authorization applications that it is likely to receive.

While the Trade and ~~restrict our ability to generate revenue~~Cooperation Agreement provides for the tariff-free trade of medicinal products between the UK and ~~achieve and sustain profitability. In addition, we~~the EU there may be ~~required~~additional non-tariff costs to ~~pay taxes or duties or~~such trade which did not exist prior to the end of the Transition Period. Further, should the UK diverge from the EU from a regulatory perspective in relation to medicinal products, tariffs could be ~~subjected to other hurdles in connection with the importation of our product candidates~~put into ~~the European Union, or we may incur expenses in establishing a manufacturing facility~~place in the ~~European Union in order to circumvent such hurdles. If any of these outcomes occur, we may be forced to restrict or delay efforts to seek regulatory approval~~future. We could therefore, both now and in the ~~United Kingdom or the European Union for our product candidates, or incur~~future, face significant additional expenses (when compared to the position prior to the end of the Transition Period) to operate our business, which could significantly and materially harm or delay our ability to generate revenues or achieve profitability of our business. Any further changes in international trade, tariff and import/export regulations as a result of Brexit or otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the UK It is also possible that Brexit may negatively affect our ability to attract and retain employees, particularly those from the EU. These developments, or the perception that any of them could occur, may significantly reduce global trade and, in particular, trade between the impacted nations and the United Kingdom.

*Cyber security risks and the failure to maintain the confidentiality, integrity and availability of our data, computer hardware, software, internet applications and related tools and functions could result in damage to our reputation and/or subject us to costs, fines, penalties, lawsuits, business interruption or otherwise adversely affect our business.*

Our business requires collecting, processing, manipulating, analyzing, disclosing and storing large amounts of ~~data.~~proprietary, confidential and sensitive data, including personal information about our employees and others, information we collect from samples we process, intellectual property, trade secrets, and proprietary business information owned or controlled by ourselves or other third parties.

The regulatory environment governing information, security and privacy ~~laws~~ is increasingly demanding and continues to evolve. Maintaining compliance with applicable security and privacy regulations may increase our operating costs. Although we have implemented physical, technical and administrative safeguards designed to protect our data, information technology systems and communications software, we are still vulnerable to natural or man-made hazards, such as natural disasters, fire, storm, flood, power loss, wind damage, terrorism, war, telecommunications failures, physical or software break-ins, inadvertent acts, malicious intrusion, malware, data leakage, viruses and similar events. Moreover, we are vulnerable to cyberattacks, malicious internet-based activity and online and offline fraud, which are prevalent and continue to increase. In addition to traditional computer “hackers,” threat actors, software bugs, malicious code (such as viruses and worms), employee theft or misuse, denial-of-service attacks (such as credential stuffing), and ransomware attacks, sophisticated nation-state and nation-state supported actors now engage in attacks (including advanced persistent threat intrusions). We may also be the subject of phishing attacks, viruses, malware installation, server malfunction, software or hardware failures, loss of data and other computer assets, adware or other similar issues. Ransomware attacks, including those from organized criminal threat actors, nation-states and nation-state supported actors, are becoming increasingly prevalent and severe and can lead to significant interruptions, delays, or outages in our operations, loss of data (including sensitive customer information), loss of income, significant extra expenses to restore data or systems, reputational loss and the diversion of funds. To alleviate the financial, operational and reputational impact of a ransomware attack, it may be preferable to make extortion payments, but we may be unwilling or unable to do so (including, for example, if applicable laws or regulations prohibit such payments). Similarly, supply chain attacks have increased in frequency and severity, and we cannot guarantee that third parties and infrastructure in our supply chain have not been compromised or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our systems and networks or the systems and networks of third parties that support us and our services. Additionally, due to the COVID-19 pandemic and our remote workforce, there is an increased risk to our information technology assets and data. These events may result in damage to or the impairment of key business processes, or the loss or corruption of confidential information, including intellectual property, proprietary business information and personal data. Such disruptions and breaches of security could have a material adverse effect on our business, financial condition and results of operations. ~~The costs~~

We could be required to usexpend significant resources, fundamentally change our business activities and practices or modify our services, software, operations or information technology in an effort to protect against security breaches and to mitigate, ~~network security problems, bugs, viruses, worms, malicious software programs~~detect and remediate actual and potential vulnerabilities and security ~~vulnerabilities could~~incidents. There can be ~~significant.~~no assurances that our security measures or those of our service providers, partners, and other third parties will be effective in protecting against all security breaches and the material adverse impacts that may arise from such breaches.

Despite the security controls we have in place, cyber events are very difficult to avoid. We have experienced specific instances of cyber events, including attempted compromises, in the past, and there could be unauthorized access, acquisition, disclosure and use of non-public information (including personal data) in the future. The techniques used ~~by criminal elements~~ to attack information technology systems are sophisticated, change frequently and may originate from less regulated and remote areas of the world. As a result, we or relevant third parties on which we rely may not be able to address these techniques proactively or implement adequate preventative measures. If our data or information technology systems (or those of third parties upon which we rely) are compromised, we could be subject to reputational damage, fines, penalties, damages, litigation and enforcement actions, and we could lose trade secrets, the occurrence of which could harm our business. In addition, such a compromise may require notification to governmental agencies, supervisory bodies, credit reporting agencies, the media or individuals pursuant to contract or various federal, state and foreign data protection, privacy and security laws, regulations and guidelines, if applicable. Such disclosures are costly, and the disclosures or the failure to comply with such requirements, could lead to material adverse impacts, including without limitation, negative publicity, a loss of customer confidence in our services or security measures or breach of contract claims. There can be no assurance that the limitations of liability in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages if we fail to comply with applicable data protection laws, privacy policies or data protection obligations related to information security or security breaches. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or adequately mitigate liabilities or damages with respect to claims, costs, expenses, litigation, fines, penalties, business loss, data loss, regulatory actions or material adverse impacts arising out of our privacy and security practices, processing or security incidents we may experience, or that such coverage will continue to be available on commercially reasonable terms or at all. The successful assertion of one or more large claims against us that exceeds our available insurance coverage, or results in changes to our insurance policies (including premium increases or the imposition of large deductible or co-insurance requirements) could have an adverse effect on our business. In addition, we cannot be sure that our existing insurance coverage and coverage for errors and omissions will continue to be available on acceptable terms or that our insurers will not deny coverage as to any future claim.

~~Changes in~~*We are subject to stringent and ~~failures~~changing privacy and data security laws, contractual obligations, self-regulatory schemes, government regulation, and standards related to data privacy and security. The actual or perceived failure by us, our customers, partners or vendors to comply with U.S. and foreign privacy and data protection laws, regulations and standards, external and internal privacy and security policies and representations, and other privacy and data-security related obligations may adversely affect our reputation, legal liability, business, operations and financial performance.*

We are subject to or affected by numerous federal, state and foreign laws and regulations, as well as regulatory guidance, governing the collection, use, disclosure, retention, processing and security of personal data, such as information that we collect about employees and patients in the United States and abroad. The global data protection landscape is rapidly evolving, and implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future. This evolution may create uncertainty in our business, affect our or our collaborators’, service providers’ and contractors’ ability to operate in certain jurisdictions or to collect, store, transfer use and share personal data, necessitate the acceptance of more onerous obligations in our contracts, result in liability or impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to increase in the future. We are also subject to the terms of our external and internal privacy and security policies, representations, certifications, standards, publications, frameworks, and contractual obligations related to our collection, processing, use and disclosure of personal data and/or other confidential information. Although we endeavor to comply with our published policies and other obligations, and take steps to ensure that our external and internal privacy and security policies and representations are not inaccurate, incomplete, deceptive, unfair, or misrepresentative of our actual practices, we may at times fail to do so or may be perceived to have failed to do so. Compliance with these and any other applicable privacy and data security laws, regulations and obligations is a rigorous and time-intensive process, and we may be required to put in place additional mechanisms, potentially at significant expense, to ensure compliance with the new data protection rules. Any failure or perceived failure by us or our collaborators, service providers and contractors to comply with federal, state or foreign laws or regulation, our internal policies and procedures, representations or our contracts governing processing, of personal data could result in negative publicity, disruptions or interruptions in our operations, fines, penalties (including changes to our data practices), lawsuits, liability, an inability to process personal data, diversion of management time and effort and proceedings against us by governmental entities or ~~others.~~others, all of which could adversely affect our business, financial condition, results of operations and growth prospects. Furthermore, the laws are not consistent, and compliance in the event of a widespread data breach is costly. In many jurisdictions, enforcement actions and consequences for noncompliance are rising.

In the United States, California adopted the California Consumer Privacy Act (“CCPA”), which became effective in January 2020. The CCPA establishes a privacy framework for covered businesses, including an expansive definition of personal information and data privacy rights for California residents. The CCPA includes a framework with potentially severe statutory damages and

private rights of action. ~~It remains unclear how the~~The CCPA ~~will be interpreted, but as currently written, it~~ may impact our business activities and exemplifies the vulnerability of our business to the evolving regulatory environment related to personal data. As we expand our operations, the CCPA may increase our compliance costs and potential liability. ~~Some observers have noted that~~The CCPA will be expanded substantially on January 1, 2023, when the California Privacy Rights Act of 2020 (“CPRA”) becomes fully operative. The CPRA will significantly modify the CCPA, ~~could mark~~including by expanding consumers’ rights with respect to certain sensitive personal information. The CPRA also creates a new state agency that will be vested with authority to implement and enforce the ~~beginning of a trend toward more stringent~~CCPA and the CPRA. We may be subject to additional U.S. privacy ~~legislation~~regulations in the ~~United States. Other~~future, including the Virginia Consumer Data Protection Act, or VCDPA, and the Colorado Privacy Act, both of which become effective in 2023. New legislation proposed or enacted in a number of states may impose, or have the potential to impose, additional obligations on companies that collect, store, use, retain, disclose, transfer and otherwise process confidential, sensitive and personal information, and will continue to shape the data privacy environment nationally. To the extent multiple state-level laws are ~~beginning~~introduced with inconsistent or conflicting standards and there is no federal law to ~~propose similar laws.~~preempt such laws, compliance with such laws could be difficult and costly to achieve.

Our operations abroad may also be subject to increased scrutiny or attention from data protection authorities. Many countries in these regions have established or are in the process of establishing privacy and data security legal frameworks with which we, our collaborators, service providers and contractors must comply. For example, the EU has adopted the General Data Protection Regulation (EU) 2016/679 (“GDPR”), which went into effect in May 2018 and introduces strict requirements for processing the personal data of individuals in the EU. The GDPR has and will continue to increase compliance burdens on us, including by mandating potentially burdensome documentation requirements and granting certain rights to individuals to control how we collect, use, disclose, retain and process information about them. The processing of sensitive personal data, such as health information, may impose heightened compliance burdens under the GDPR and is a topic of active interest among foreign regulators. In addition, the GDPR provides for more robust regulatory enforcement and fines of up to €20 million or 4% of the annual global revenue of the noncompliant company, whichever is greater. As we expand into other foreign countries and jurisdictions, we may be subject to additional laws and regulations that may affect how we conduct business. Further, the UK’s decision to leave the EU, often referred to as Brexit, has created uncertainty with regard to the regulation of data protection in the UK, including with respect to whether laws or regulations will apply to us consistent with the GDPR in the future and how data transfers to and from the UK will be regulated.

European data protection laws, including the GDPR, generally restrict the transfer of personal data from Europe, including the European Economic Area, United Kingdom and Switzerland, to the United States and most other countries unless the parties to the transfer have implemented specific safeguards to protect the transferred personal data. One of the primary safeguards allowing U.S. companies to import personal data from Europe has been certification to the EU-U.S. Privacy Shield and Swiss-U.S. Privacy Shield frameworks administered by the U.S. Department of Commerce. However, the Court of Justice of the European Union recently invalidated the EU-U.S. Privacy Shield. The same decision also raised questions about whether one of the primary alternatives to the EU-U.S. Privacy Shield, namely, the European Commission’s Standard Contractual Clauses, can lawfully be used for personal data transfers from Europe to the United States or most other countries. AtThe European Commission recently proposed updates to the SCCs, and additional regulatory guidance has been released that seeks to impose additional obligations on companies seeking to rely on the SCCs. However, at present, there are few, if any, viable alternatives to the EU-U.S. Privacy Shield and the Standard Contractual Clauses. ~~Authorities in~~Similarly, the Swiss Federal Data Protection and Information Commissioner recently opined that the Swiss-U.S. Privacy Shield is inadequate for transfers from Europe to the United ~~Kingdom~~States and ~~Switzerland,~~the United Kingdom, whose data protection laws are similar to those of the European Union, may similarly invalidate use of the EU-U.S. Privacy Shield and Swiss-U.S. Privacy Shield, respectively, as mechanisms for lawful personal data transfers from those countries to the United States. As such, if we are unable to rely valid data transfer solution for personal data transfers for Europe, we will face increased exposure to substantial fines under European data protection laws as well as injunctions against processing personal data from Europe. Inability to import personal data from the European Economic Area, United Kingdom or Switzerland may also restrict our activities in Europe; limit our ability to collaborate with service providers, contractors and other companies subject to European data protection laws; and require us to increase our data processing capabilities in Europe at significant expense. Additionally, other countries outside of Europe have enacted or are considering enacting similar cross-border data transfer restrictions and laws requiring local data residency, which could increase the cost and complexity of delivering our services and operating our business.

Compliance with these and any other applicable privacy and data security laws and regulations is a rigorous and time-intensive process, and we may be required to put in place additional mechanisms to ensure compliance with the new data protection rules. If we

fail to comply with any such laws or regulations, we may face significant fines and penalties (including changes in our data practices), claims for damages, reputational damage all of which could adversely affect our business, financial condition, results of operations and growth prospects. Furthermore, the laws are not consistent, and compliance in the event of a widespread data breach is costly.

We publish privacy policies and other documentation regarding our collection, processing, use and disclosure of personal data and/or other confidential information. Although we endeavor to comply with our published policies and documentation, we may at times fail to do so or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if our employees or vendors to comply with our published policies and documentation. Such failures can subject us to potential foreign, local, state and federal action if they are found to be deceptive, unfair, or misrepresentative of our actual practices.

Approval and/or clearance by the FDA and foreign regulatory authorities for any diagnostic tests will take significant time and require significant research, development and clinical study expenditures and ultimately may not succeed.*

Before we begin to label and market our products for use as clinical diagnostics in the United States, including as companion diagnostics, unless an exemption applies, we will be required to obtain either 510(k) clearance or PMA from the FDA. In addition, we may be required to seek FDA clearance or approval for any changes or modifications to our products that could significantly affect their safety or effectiveness or would constitute a change in intended use. The PMA and 510(k) clearance processes can be expensive, time-consuming and uncertain. In addition to the time required to conduct clinical studies, if necessary, it generally takes from four to twelve months from submission of an application to obtain 510(k) clearance, and nine to 18 months for a PMA; however, it may take longer, and 510(k) clearance or PMA approval may never be obtained. Even if the FDA accepts a 510(k) or PMA submission for filing, the FDA may request additional information or clinical studies during its review. Our ability to obtain additional regulatory clearances or approvals for new products and indications may be significantly delayed or may never be obtained. The requirements of the more rigorous PMA process could delay product introductions and increase the costs associated with FDA compliance. As with all IVD products, the FDA reserves the right to redefine the regulatory path at the time of submission or during the review process and could require a more burdensome approach. Even if we were to obtain regulatory approval or clearance, it may not be for the uses we believe are important or commercially attractive, in which case we would not be permitted to market our product for those uses.

A 510(k) clearance or PMA submission for any future medical device product would likely place substantial restrictions on how the device is marketed or sold, and we will be required to continue to comply with extensive regulatory requirements, including, but not limited to Quality ~~System~~Systems Regulations (“QSRs”), registering manufacturing facilities, listing the products with the FDA, and complying with labeling, marketing, complaint handling, adverse event and medical device reporting requirements and corrections and removals. We cannot assure you that we will successfully maintain the clearances or approvals we may receive in the future. In addition, any clearances or approvals we obtain may be revoked if any issues arise that bring into question our products’ safety or effectiveness. Any failure to maintain compliance with FDA regulatory requirements could harm our business, financial condition and results of operations.

Sales of our diagnostic products outside the United States will be subject to foreign regulatory requirements governing clinical studies, vigilance reporting, marketing approval, manufacturing, product licensing, pricing and reimbursement. These regulatory requirements vary greatly from country to country. As a result, the time required to obtain approvals outside the United States may differ from that required to obtain FDA approval and we may not be able to obtain foreign regulatory approvals on a timely basis or at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure approval by regulatory authorities in other countries or by the FDA and foreign regulatory authorities could require additional testing. In addition, the FDA regulates exports of medical devices. Failure to comply with these regulatory requirements or obtain required approvals could impair our ability to commercialize our diagnostic products outside of the United States.

Our research use only products for the life sciences market could become subject to regulation as medical devices by the FDA or other regulatory agencies in the future, which could increase our costs and delay our commercialization efforts, thereby materially and adversely affecting our life sciences business and results of operations.

In the United States, our products are currently labeled and sold for research use only, and not for the diagnosis or treatment of disease, and are sold to a variety of parties, including biopharmaceutical companies, academic institutions and molecular labs. Because such products are not intended for use in clinical practice in diagnostics, and the products cannot include clinical or diagnostic claims, they are exempt from many regulatory requirements otherwise applicable to medical devices. In particular, while the FDA regulations require that RUO products be labeled, “For Research Use Only. Not for use in diagnostic procedures,” the regulations do not otherwise subject such products to the FDA’s pre- and post-market controls for medical devices.

A significant change in the laws governing RUO products or how they are enforced may require us to change our business model in order to maintain compliance. For instance, in November 2013 the FDA issued a guidance document entitled “Distribution of In Vitro Diagnostic Products Labeled for Research Use Only or Investigational Use Only” (the “RUO Guidance”) which highlights the FDA’s interpretation that distribution of RUO products with any labeling, advertising or promotion that suggests that clinical laboratories can validate the test through their own procedures and subsequently offer it for clinical diagnostic use as a laboratory developed test is in conflict with RUO status. The RUO Guidance further articulates the FDA’s position that any assistance offered in performing clinical validation or verification, or similar specialized technical support, to clinical laboratories, conflicts with RUO status. If we engage in any activities that the FDA deems to be in conflict with the RUO status held by the products that we sell, we may be subject to immediate, severe and broad FDA enforcement action that would adversely affect our ability to continue operations. Accordingly, if the FDA finds that we are distributing our RUO products in a manner that is inconsistent with its regulations or guidance, we may be forced to stop distribution of our RUO tests until we are in compliance, which would reduce our ~~revenues,~~revenue, increase our costs and adversely affect our business, prospects, results of operations and financial condition. In addition, the FDA’s proposed implementation for a new framework for the regulation of ~~laboratory developed tests (“LDTs”)~~LDTs may negatively impact the LDT market and thereby reduce demand for RUO products.

If the FDA requires marketing authorization of our RUO products in the future, there can be no assurance that the FDA will ultimately grant any clearance or approval requested by us in a timely manner, or at all.

We expect to rely on third parties to conduct any future studies of our diagnostic products that may be required by the FDA or other regulatory authorities, and those third parties may not perform satisfactorily.

We do not have the ability to independently conduct the clinical studies or other studies that may be required to obtain FDA and other regulatory clearance or approval for our diagnostic products, including the HTG EdgeSeq ~~system~~instrument and related proprietary panels. Accordingly, we expect to rely on third parties, such as medical institutions, CRO’s and clinical investigators, and providers of NGS instrumentation, to conduct such studies and/or to provide information necessary for our submissions to regulatory authorities. Our reliance on these third parties for clinical development activities or information will reduce our control over these activities. These third parties may not complete activities on schedule or conduct studies in accordance with regulatory requirements or our study design. Similarly, providers of NGS instrumentation may not place the same importance on our regulatory submissions as we do. Our reliance on third parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, the various procedures ~~requires~~required under good clinical practices, or the submission of all information required in connection with requested regulatory approvals. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines if the third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our studies may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for our diagnostic products.

Even if we are able to obtain regulatory approval or clearance for our diagnostic products, we will continue to be subject to ongoing and extensive regulatory requirements, and our failure to comply with these requirements could substantially harm our business.

If we receive regulatory approval or clearance for our diagnostic products, we will be subject to ongoing FDA obligations and continued regulatory oversight and review, such as compliance with QSRs, inspections by the FDA, continued adverse event and malfunction reporting, corrections and removals reporting, registration and listing, and promotional restrictions, and we may also be subject to additional FDA post-marketing obligations. If we are not able to maintain regulatory compliance, we may not be permitted to market our diagnostic products and/or may be subject to fines, injunctions, and civil penalties; recall or seizure of products; operating restrictions; and criminal prosecution. In addition, we may be subject to similar regulatory compliance actions of foreign jurisdictions.

*If Medicare and other third-party payors in the United States and foreign countries do not approve coverage and adequate reimbursement for our future clinical diagnostic tests enabled by our technology, the commercial success of our diagnostic products would be compromised.*

We plan to develop, obtain regulatory approval for and sell clinical diagnostics products for a number of different indications. Successful commercialization of our clinical diagnostic products depends, in large part, on the availability of coverage and adequate reimbursement for testing services using our diagnostic products from third-party payors, including government insurance plans, managed care organizations and private insurance plans. There is significant uncertainty surrounding third-party coverage and reimbursement for the use of tests that incorporate new technology, such as the HTG EdgeSeq ~~system~~platform and related applications and assays. Reimbursement rates have the potential to fluctuate depending on the region in which the testing is provided, the type of facility or treatment center at which the testing is done, and the third-party payor responsible for payment. If our customers are unable to obtain positive coverage decisions from third-party payors approving reimbursement for our tests at adequate levels, the commercial success of our products would be compromised, and our revenue would be significantly limited. Even if we do obtain favorable reimbursement for our tests, third-party payors may withdraw their coverage policies, review and adjust the rate of

reimbursement, require co-payments from patients or stop paying for our tests, which would reduce revenue for testing services based on our technology and demand for our diagnostic products.

The American Medical Association Current Procedural Terminology (“CPT”) Editorial Panel created ~~new~~ CPT codes that could be used by our customers to report testing for certain large-scale multianalyte genomic sequencing procedures (“GSPs”), including our diagnostic products, if approved. Effective January 1, 2015, these codes allow for uniform reporting of broad genomic testing panels using technology similar to ours. While these codes standardize reporting for these tests, coverage and payment rates for GSPs remain uncertain and we cannot guarantee that coverage and reimbursement for these tests will be provided in the amounts we expect, or at all. Initially, industry associations recommended that payment rates for GSPs be cross-walked to existing codes on the clinical laboratory fee schedule. On October 27, 2014, Centers for Medicare and Medicaid Services (“CMS”) issued preliminary determinations for 29 new molecular pathology codes, including the GSPs, of gapfill rather than crosswalking as recommended by the Association for Molecular Pathology. This means that local private Medicare Administrative Contractors, such as Palmetto, Novidian, Novitas and Cahaba, were instructed to determine the appropriate fee schedule amounts in the first year, and CMS calculated a national payment rate based on the median of those local fee schedule amounts in the second year. This process may make it more difficult for our customers to obtain coverage and adequate reimbursement for testing services using our diagnostic products. We cannot assure that CMS and other third-party payors will establish reimbursement rates sufficient to cover the costs incurred by our customers in using our clinical diagnostic products, if approved. On September 22, 2017, gapfill pricing was set for three CPT codes which our customers may potentially utilize to obtain reimbursement, subject to regulatory limitations, for the use of our products. CPTs 81445 and 81450, for the assessment of 5-50 genes in solid and liquid tumors, respectively, were set at $602 and $760, respectively, and remains the same as of September 30, 2020. Additionally, CPT 81455 for the assessment of 51 or more genes in solid and liquid tumors was set at $2,920.

Even if we are able to establish coverage and reimbursement codes for our clinical diagnostic products in development, we will continue to be subject to significant pricing pressure, which could harm our business, results of operations, financial condition and prospects.

Third-party payors, including managed care organizations as well as government payors such as Medicare and Medicaid, have increased their efforts to control the cost, utilization and delivery of healthcare services, which may include decreased coverage or reduced reimbursement. From time to time, Congress has considered and implemented changes to the Medicare fee schedules in conjunction with budgetary legislation, and pricing and payment terms, including the possible requirement of a patient co-payment for Medicare beneficiaries for laboratory tests covered by Medicare, and are subject to change at any time. Reductions in the reimbursement rate of third-party payors have occurred and may occur in the future. Reductions in the prices at which testing services based on our technology are reimbursed in the future could result in pricing pressures and have a negative impact on our revenue. In many countries outside of the United States, various coverage, pricing and reimbursement approvals are required. We expect that it will take several years to establish broad coverage and reimbursement for testing services based on our products with payors in countries outside of the United States, and our efforts may not be successful.

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws and other federal and state healthcare laws applicable to our business and marketing practices. If we are unable to comply, or have not complied, with such laws, we could face substantial penalties.*

Our operations may be, and may continue to be, directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal and state anti-kickback statutes, false claims statutes, civil monetary penalties laws, patient data privacy and security laws, physician transparency laws and marketing compliance laws. These laws may impact, among other things, our proposed sales and marketing and education programs.

The laws that may affect our ability to operate include, but are not limited to:

Promotional activities for FDA-regulated products have been the subject of significant enforcement actions brought under healthcare reimbursement laws, fraud and abuse laws, and consumer protection statutes, among other theories. Advertising and promotion of medical devices are also regulated by the Federal Trade Commission and by state regulatory and enforcement authorities. In addition, under the Federal Lanham Act and similar state laws, competitors and others can initiate litigation relating to advertising claims.

In addition, the approval and commercialization of any of our product candidates outside the United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it is possible that some of our business activities, including our relationships with physicians and other health care providers, and our evaluation, reagent rental and collaborative development agreements with customers, and sales and marketing efforts could be subject to challenge under one or more of such laws.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to significant penalties, including administrative, civil and criminal penalties, damages, fines, imprisonment, disgorgement, exclusion from participation in federal healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, additional reporting requirements and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

Our employees, independent contractors, principal investigators, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, principal investigators, consultants, commercial partners and vendors. Misconduct by these parties could include intentional, reckless or negligent failures to, among other things: (i) comply with the regulations of the FDA, CMS, the Department of Health and Human Services Office of Inspector General (“OIG”) and other similar foreign regulatory bodies; (ii) provide true, complete and accurate information to the FDA and other similar regulatory bodies; (iii) comply with manufacturing standards we have established; (iv) comply with healthcare fraud and abuse laws and regulations in the United States and similar foreign fraudulent misconduct laws; or (v) report financial information or data accurately, or disclose unauthorized activities to us. These laws may impact, among other things, our activities with collaborators and key opinion leaders, as well as our sales, marketing and education programs. In particular, the promotion, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained in the course of clinical studies, which could result in regulatory sanctions and cause serious harm to our reputation. We currently have a code of conduct applicable to all of our employees,

but it is not always possible to identify and deter employee misconduct, and our code of conduct and the other precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses, or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, additional reporting requirements and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and curtailment of our operations. Any of these actions or investigations could result in substantial costs to us, including legal fees, and divert the attention of management from operating our business.

*Healthcare policy changes, including recently enacted legislation reforming the United States healthcare system, may have a material adverse effect on our financial condition and results of operations.*

On April 1, 2014, the Protecting Access to Medicare Act of 2014 (“PAMA”) was signed into law, which, among other things, significantly altered the current payment methodology under the Medicare Clinical Laboratory Fee Schedule (“CLFS”). Effective January 1, 2018, the CLFS is based on weighted median private payor rates as required by PAMA. Under the law, starting January 1, 2016 and every three years thereafter (or annually in the case of advanced diagnostic lab tests), applicable clinical laboratories must report laboratory test payment data for each Medicare-covered clinical diagnostic lab test that it furnishes. The most recent data collection period was from January 1 ~~2019~~ through June 30, 2019, ~~and was~~ followed by a six-month validation period from July 1, 2019 through December 31, 2019. Thereafter, applicable laboratories will report their data. The reported data must include the payment rate (reflecting all discounts, rebates, coupons and other price concessions) and the volume of each test that was paid by each private payor (including health insurance issuers, group health plans, Medicare Advantage plans and Medicaid managed care organizations). In January 2020, CMS announced that data reporting for clinical diagnostic laboratory tests is delayed by one year. Moreover, the CARES Act, enacted in March 2020, further delays the reporting period by an additional year. Therefore, data that was ~~supposed~~originally required to be reported between January 1, 2020 and March 31, 2020 must now be reported between January 1, ~~2021~~2022 and March 31, ~~2021.~~2022. Covered laboratories must report data from the original data collection period of January 1, 2019 through June 30, 2019. Data reporting for these tests will then resume on a three-year cycle beginning in ~~2024.~~2025. The payment rate applies to laboratory tests furnished by a hospital laboratory if the test is separately paid under the hospital outpatient prospective payment system. It is still too early to predict the full impact on reimbursement for our products in development. In addition, CMS updated the statutory phase-in provisions such that, for 2020, the rates for clinical diagnostic laboratory tests may not be reduced by more than 10% of the rates for 2019. ~~Additionally, there will be~~ Pursuant to the CARES Act, the statutory phase-in of payment reductions has been extended through 2024, with a 0% reduction cap for 2021, and a 15% reduction cap for each of ~~2021,~~ 2022, 2023, and ~~2023.~~2024.

Also, under PAMA, CMS is required to adopt temporary billing codes to identify new tests and new advanced diagnostic laboratory tests that have been cleared or approved by the FDA. For an existing test that is cleared or approved by the FDA and for which Medicare payment is made as of April 1, 2014, CMS is required to assign a unique billing code if one has not already been assigned by the agency. In addition to assigning the code, CMS was required to publicly report payment for the tests. We cannot determine at this time the full impact of the law, including its implementing regulations, on our business, financial condition and results of operations.

The ~~ACA~~Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “ACA”), made changes that significantly impacted the biopharmaceutical and medical device industries and clinical laboratories. For example, the ACA imposes a multifactor productivity adjustment to the reimbursement rate paid under Medicare for certain clinical diagnostic laboratory tests, which may reduce payment rates. These or any future proposed or mandated reductions in payments may apply to some or all of the clinical laboratory tests that our diagnostics customers use our technology to deliver to Medicare beneficiaries, and may reduce demand for our diagnostic products.

Other significant measures contained in the ACA include, for example, coordination and promotion of research on comparative clinical effectiveness of different technologies and procedures, initiatives to revise Medicare payment methodologies, such as bundling of payments across the continuum of care by providers and physicians, and initiatives to promote quality indicators in payment methodologies. The ACA also includes significant new fraud and abuse measures, including required disclosures of financial arrangements with physician customers, lower thresholds for violations and increasing potential penalties for such violations. However, the future of the ACA is uncertain. There ~~remain~~have been executive, judicial and Congressional challenges to certain aspects of the ~~ACA, as well as efforts by the~~ACA. For example, then-President Trump administration to repeal or replace certain aspects of the ACA. As a result, there have been delays in the implementation of, and action taken to repeal or replace, certain aspects of the ACA. Since January 2017, President Trump has signed several Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. ~~Concurrently,~~ Congress ~~has~~ considered legislation ~~that would~~to repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA. For example, the Tax Act includes a provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate”. ~~In addition,~~On June 17, 2021, the ~~2020~~

~~federal spending package permanently eliminated, effective January 1, 2020, the ACA-mandated medical device tax and “Cadillac” tax~~U.S. Supreme Court dismissed a challenge on ~~high-cost employer-sponsored health coverage and, effective January 1, 2021, also eliminates the health insurer tax. On December 14, 2018, a Texas U.S. District Court Judge ruled~~procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by ~~Congress as part of~~Congress. Thus, the ~~Tax Act. Additionally, on December 18, 2019,~~ACA will remain in effect in its current form. Further, prior to the U.S. ~~Court of Appeals for the 5th Circuit upheld the District~~Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace, which began on February 15, 2021 and remained open through August 15, 2021. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is possible that the ~~individual mandate was unconstitutional and remanded~~ACA will be subject to judicial or Congressional challenges in the ~~case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well.On March 2, 2020, the United States Supreme Court granted the petitions for writs of certiorari to review the case.~~future. It is unclear how ~~this litigation~~such challenges and ~~other efforts to repeal and replace ACA~~the healthcare reform measures of the Biden administration will impact the ACA and our business. ~~We continue to evaluate the effect that the ACA and its possible repeal and replacement has on our business.~~

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, then-President Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend to Congress proposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013, and, following the passage of other legislative amendments, including the Bipartisan Budget Act of 2018, will stay in effect through 2030 unless additional Congressional action is taken. ~~The~~However, COVID-19 relief legislation, including the CARES Act, has suspended the 2% Medicare sequester from May 1, 2020 through December 31, ~~2020, and extended the sequester by one year, through 2030.~~2021. On January 2, 2013, then-President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, including hospitals, imaging centers and cancer treatment centers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Various healthcare reform proposals have also emerged from federal and state governments. Changes in healthcare law or policy, such as the creation of broad test utilization limits for diagnostic products in general or requirements that Medicare patients pay for portions of clinical laboratory tests or services received, could substantially impact the sales of our tests, increase costs and divert management’s attention from our business. In addition, sales of our tests outside of the United States will subject us to foreign regulatory requirements, which may also change over time.

We cannot predict whether future healthcare initiatives will be implemented at the federal or state level or in countries outside of the United States in which we may do business, or the effect any future legislation or regulation will have on us. The full impact of the ACA, as well as other laws and reform measures that may be proposed and adopted in the future, remains uncertain, but may continue the downward pressure on medical device pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs, which could have a material adverse effect on our business operations.

*If we are unable to protect our intellectual property effectively, our business will be harmed.

We rely on patent protection as well as trademark, copyright, trade secret and other intellectual property rights protection and contractual restrictions to protect our proprietary technologies, all of which provide limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. Our U.S. and foreign patent and patent application portfolio relates to our nuclease-protection-based technologies as well as to lung cancer and melanoma and DLBCL biomarker panels discovered using our nuclease-protection-based technology. We have exclusive or non-exclusive licenses to multiple U.S. and foreign patents and patent applications covering technologies that we may elect to utilize in developing diagnostic tests for use on our HTG EdgeSeq ~~system.~~platform. Those licensed patents and patent applications cover technologies related to the diagnosis of breast cancer and melanoma.

If we fail to protect our intellectual property, third parties may be able to compete more effectively against us and we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property.

We cannot assure investors that any of our currently pending or future patent applications will result in issued patents, and we cannot predict how long it will take for such patents to be issued. Further, we cannot assure investors that other parties will not challenge any patents issued to us or that courts or regulatory agencies will hold our patents to be valid or enforceable. We cannot guarantee investors that we will be successful in defending challenges made against our patents. Any successful third-party challenge to our patents could result in the unenforceability or invalidity of such patents.

The patent positions of life sciences companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in such companies’ patents has emerged to date in the United States. Furthermore, in the biotechnology field, courts frequently render opinions that may

adversely affect the patentability of certain inventions or discoveries, including opinions that may adversely affect the patentability of methods for analyzing or comparing nucleic acids molecules, such as RNA or DNA.

The patent positions of companies engaged in development and commercialization of molecular diagnostic tests are particularly uncertain. Various courts, including the U.S. Supreme Court, have recently rendered decisions that impact the scope of patentability of certain inventions or discoveries relating to molecular diagnostics. Specifically, these decisions stand for the proposition that patent claims that recite laws of nature (for example, the relationships between gene expression levels and the likelihood of risk of recurrence of cancer) are not themselves patentable unless those patent claims have sufficient additional features that provide practical assurance that the processes are genuine inventive applications of those laws rather than patent drafting efforts designed to monopolize the law of nature itself. What constitutes a “sufficient” additional feature is uncertain. Accordingly, this evolving case law in the United States may adversely impact our ability to obtain new patents and may facilitate third-party challenges to our existing owned and licensed patents.

The laws of some non-U.S. countries do not protect intellectual property rights to the same extent as the laws of the United States, and many companies have encountered significant problems in protecting and defending such rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of our patents. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

Changes in either the patent laws or in interpretations of patent laws in the United States or other countries may diminish the value of our intellectual property. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. For example:

In addition to pursuing patents on our technology, we take steps to protect our intellectual property and proprietary technology by entering into confidentiality agreements and intellectual property assignment agreements with our employees, consultants, corporate partners and, when needed, our advisors. Such agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements, and we may not be able to prevent such unauthorized disclosure. Monitoring unauthorized disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If we were to enforce a claim that a third-party had illegally obtained and was using our trade secrets, it would be expensive and time consuming, and the outcome would be unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets.

In addition, competitors could purchase our products and attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside of our intellectual property rights. If our intellectual property is not adequately protected so as to protect our market against competitors’ products and methods, our competitive position could be adversely affected, as could our business.

We have not yet registered certain of our trademarks, including “HTG Edge,” “HTG EdgeSeq,” “VERI/O,” “qNPA,” “HTG Transcriptome Panel” and ~~“qNPA,”~~“HTG EpiEdgeSeq” in all of our potential markets. If we apply to register these trademarks, our applications may not be allowed for registration, and our registered trademarks may not be maintained or enforced. In addition, opposition or cancellation proceedings may be filed against our

trademark applications and registrations, and our trademarks may not survive such proceedings. If we do not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties than we otherwise would.

To the extent our intellectual property, including licensed intellectual property, offers inadequate protection, or is found to be invalid or unenforceable, we would be exposed to a greater risk of direct competition. If our intellectual property does not provide adequate protection against our competitors’ products, our competitive position could be adversely affected, as could our business. Both the patent application process and the process of managing patent disputes can be time consuming and expensive.

~~We may need to depend on certain technologies that are licensed to us. We do not control these technologies and any loss of our rights to them could prevent us from selling some of our products.~~

We have entered into several license agreements with third parties for certain licensed technologies that are, or may become relevant to the products we market, or plan to market. In addition, we may in the future elect to license third-party intellectual property to further our business objectives and/or as needed for freedom to operate for our products. We do not and will not own the patents, patent applications or other intellectual property rights that are a subject of these licenses. Our rights to use these technologies and employ the inventions claimed in the licensed patents, patent applications and other intellectual property rights are or will be subject to the continuation of and compliance with the terms of those licenses.

We might not be able to obtain licenses to technology or other intellectual property rights that we require. Even if such licenses are obtainable, they may not be available at a reasonable cost or multiple licenses may be needed for the same product (e.g., stacked royalties). We could therefore incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our margins. Further, we could encounter delays in product introductions, or interruptions in product sales, as we develop alternative methods or products.

In some cases, we do not or may not control the prosecution, maintenance, or filing of the patents or patent applications to which we hold licenses, or the enforcement of these patents against third parties. As a result, we cannot be certain that drafting or prosecution of the licensed patents and patent applications by the licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights.

Certain of the U.S. patent rights we own, have licensed or may license relate to technology that was developed with U.S. government grants, in which case the U.S. government has certain rights in those inventions, including, among others, march-in license rights. In addition, federal regulations impose certain domestic manufacturing requirements with respect to any products within the scope of those U.S. patent claims.

*We may be involved in lawsuits to protect or enforce our patent or other proprietary rights, to determine the scope, coverage and validity of others’ patent or other proprietary rights, or to defend against third-party claims of intellectual property infringement, any of which could be time-intensive and costly and may adversely impact our business or stock price.

We may from time to time receive notices of claims of infringement and misappropriation or misuse of other parties’ proprietary rights, including with respect to third-party trade secrets, infringement by us of third-party patents and trademarks or other rights, or challenges to the validity or enforceability of our patents, trademarks or other rights. Some of these claims may lead to litigation. We cannot assure investors that such actions will not be asserted or prosecuted against us or that we will prevail in any or all such actions.

Litigation may be necessary for us to enforce our patent and other proprietary rights or to determine the scope, coverage and validity of the proprietary rights of others. The outcome of any litigation or other proceeding is inherently uncertain and might not be favorable to us. In addition, any litigation that may be necessary in the future could result in substantial costs, even if we were to prevail, and diversion of resources and could have a material adverse effect on our business, operating results or financial condition.

As we move into new markets and applications for our products, incumbent participants in such markets may assert their patents and other proprietary rights against us as a means of slowing our entry into such markets or as a means to extract substantial license and royalty payments from us. Our competitors and others may now and in the future have significantly larger and more mature patent portfolios than we currently have. In addition, future litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents may provide little or no deterrence or protection. Therefore, our commercial success may depend in part on our non-infringement of the patents or proprietary rights of third parties. Numerous significant intellectual property issues have been litigated, and will likely continue to be litigated, between existing and new participants in our existing and targeted markets and competitors may assert that our products infringe their intellectual property rights as part of a business strategy to impede our successful entry into those markets. We have not conducted comprehensive freedom-to-operate searches to determine whether the commercialization of our products or other business activities would infringe patents issued to third parties. Third parties may assert that we are employing their proprietary technology without authorization. In addition, our competitors and others may have patents or may in the future obtain patents and claim that use of our products infringes these patents.

We could incur substantial costs and divert the attention of our management and technical personnel in defending against any of these claims. Parties making claims against us may be able to obtain injunctive or other relief, which could block our ability to develop, commercialize and sell products, and could result in the award of substantial damages against us. In the event of a successful claim of infringement against us, we may be required to pay damages and obtain one or more licenses from third parties or be prohibited from selling certain products. We may not be able to obtain these licenses at a reasonable cost, if at all. We could therefore incur substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our margins. In addition, we could encounter delays in product introductions while we attempt to develop alternative methods or products to avoid infringing third-party patents or proprietary rights. Defense of any lawsuit or failure to obtain any of these licenses on favorable terms could prevent us from commercializing products, and the prohibition of sale of any of our products could materially affect our ability to grow and gain market acceptance for our products.

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. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.

In addition, our agreements with some of our suppliers, distributors, customers and other entities with whom we do business require us to defend or indemnify these parties to the extent they become involved in infringement claims against us, including the claims described above. We could also voluntarily agree to defend or indemnify third parties in instances where we are not obligated to do so if we determine it would be important to our business relationships. If we are required or agree to defend or indemnify any of these third parties in connection with any infringement claims, we could incur significant costs and expenses that could adversely affect our business, operating results, or financial condition.

We may need to depend on certain technologies that are licensed to us. We do not control these technologies and any loss of our rights to them could prevent us from selling some of our products.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our employees’ former employers.

Many of our employees were previously employed at other medical diagnostic companies, including our competitors or potential competitors. Although no claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights. A loss of key research personnel work product could hamper or prevent our ability to commercialize certain potential products, which could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Our products contain third-party ~~open source~~open-source software components, and failure to comply with the terms of the underlying ~~open source~~open-source software licenses could restrict our ability to sell our products.

Our products contain software tools licensed by third-party authors under ~~“open source”~~“open-source” licenses. Use and distribution of ~~open source~~open-source software may entail greater risks than use of third-party commercial software, as ~~open source~~open-source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Some ~~open source~~open-source licenses contain requirements that we make available source code for modifications or derivative works we create based upon the type of ~~open source~~open-source software we use. If we combine our proprietary software with ~~open source~~open-source software in a certain manner, we could, under certain ~~open source~~open-source licenses, be required to release the source code of our proprietary software to the public. This would allow our competitors to create similar products with less development effort and time and ultimately could result in a loss of product sales.

Although we monitor our use of ~~open source~~open-source software to avoid subjecting our products to conditions we do not intend, the terms of many ~~open source~~open-source licenses have not been interpreted by U.S. courts, and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products. Moreover, we cannot assure investors that our processes for controlling our use of ~~open source~~open-source software in our products will be effective. If we are held to have breached the terms of an ~~open source~~open-source software license, we could be required to seek licenses from third parties to continue offering our products on terms that are not economically feasible, to re-engineer our products, to discontinue the sale of our products if re-engineering could not be accomplished on a timely basis, or to make generally available, in source code form, our proprietary code, any of which could adversely affect our business, operating results, and financial condition.

We use third-party software that may be difficult to replace or cause errors or failures of our products that could lead to lost customers or harm to our reputation.

We use software licensed from third parties in our products. In the future, this software may not be available to us on commercially reasonable terms, or at all. Any loss of the right to use any of this software could result in delays in the production of our products until equivalent technology is either developed by us, or, if available, is identified, obtained and integrated, which could harm our business. In addition, any errors or defects in third-party software, or other third-party software failures could result in errors, defects or cause our products to fail, which could harm our business and be costly to correct. Many of these providers attempt to impose limitations on their liability for such errors, defects or failures, and if enforceable, we may have additional liability to our customers or third-party providers that could harm our reputation and increase our operating costs.

We will need to maintain our relationships with third-party software providers and to obtain software from such providers that do not contain any errors or defects. Any failure to do so could adversely impact our ability to deliver reliable products to our customers and could harm our results of operations.

Complying with the laws and regulations affecting public companies increases our costs and the demands on management and could harm our operating results.*

As a public company, we will continue to incur significant legal, accounting and other expenses. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and operating results. In addition, the Sarbanes-Oxley Act and rules subsequently implemented by the SEC and Nasdaq, impose numerous requirements on public companies, including corporate governance requirements. Our management and other personnel will need to continue to devote a substantial amount of time to compliance with these laws and regulations. These requirements have resulted and will continue to result in significant legal, accounting, and financial compliance costs and have made and will continue to make some activities more time consuming and costly.

As ~~an “emerging growth company,”~~a “non-accelerated filer” we have availed ourselves of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404. ~~However, we may no longer avail ourselves of this exemption when we cease to be an “emerging growth company” unless we are a “non-accelerated filer.”~~ When our independent registered public accounting firm is required to undertake an assessment of our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our compliance with applicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would require additional financial and management resources.

Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the market price of our stock. Irrespective of compliance with Section 404, any failure of our internal control over financial reporting could have a material adverse effect on our stated operating results and harm our reputation. If we are unable to implement these requirements effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in an adverse opinion on our internal controls from our independent registered public accounting firm.

*We are ~~an “emerging growth company,” and~~ a “smaller reporting company” and a “non-accelerated filer” and any decision on our part to comply only with certain reduced reporting and disclosure requirements applicable to ~~emerging growth~~smaller reporting companies or ~~smaller reporting companies~~non-accelerated filers could make our common stock less attractive to investors.

We are ~~an “emerging growth company,” as defined in the JOBS Act, enacted in April 2012, and~~ a “smaller reporting ~~company,”~~company” and a “non-accelerated filer” as defined in the Exchange Act, and for as long as we continue to be ~~an “emerging growth~~a “smaller reporting company” or a ~~“smaller reporting company,~~“non-accelerated filer,” we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to ~~“emerging growth~~“smaller reporting companies” or ~~“smaller reporting companies,~~“non-accelerated filers,” including, but not limited to, not being required to have our independent registered public accounting firm audit our internal control over financial reporting under Section 404 (for so long as we are ~~an “emerging growth company” or~~ a “non-accelerated filer”), and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements (for so long as we are ~~an “emerging growth company” or~~ a “smaller reporting company”), and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved (for so long as we are an “emerging growth company”). ~~We will be an “emerging growth company” until December 31, 2020.~~ We expect to be both a “smaller reporting company” and a “non-accelerated ~~filer~~filer” in ~~2021.~~2022. We cannot predict if investors will find our common stock less attractive if we choose to rely on these exemptions. If

some investors find our common stock less attractive as a result of any choices to reduce future disclosure, there may be a less active trading market for our common stock and our stock price may be more volatile.

The trading price of our common stock may be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include:

The stock market in general, and market prices for the securities of health technology companies like ours in particular, have from time to time experienced volatility that often has been unrelated to the operating performance of the underlying companies. ~~The ongoing~~ COVID-19, ~~pandemic,~~ for example, has resulted in significant volatility in the stock market over the last several months. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. In several recent situations where the market price of a stock has been volatile, holders of that stock have instituted securities class action litigation against the company that issued the stock. If any of our stockholders were to bring a lawsuit against us, the defense and disposition of the lawsuit could be costly and divert the time and attention of our management and harm our operating results.

In addition, to date our common stock has generally been sporadically and thinly traded. As a consequence, the trading of relatively small quantities of our shares may disproportionately influence the price of our common stock in either direction. The price for our common stock could decline precipitously if even a moderate amount of our common stock is sold on the market without commensurate demand.

*Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.*

We expect that significant additional capital will be needed in the future to continue our planned operations. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by these and subsequent sales. New investors could also gain rights superior to our existing stockholders.

Pursuant to our 2020 Equity Incentive Plan (“2020 Plan”) our Board of Directors is authorized to grant stock options and other equity-based awards to our employees, directors and consultants. In addition, our ~~Board of Directors approved the granting of rights to eligible employees to purchase shares of our common stock pursuant to our~~amended and restated 2014 Employee Stock Purchase Plan (“ESPP”) ~~beginning January 1, 2016. The number of~~authorizes us to offer, sell and issue shares ofto our common stock reserved for issuance under the ESPP will automatically increase on January 1 of each calendar year by the lesser of 1% of the total number of shares of our common stock outstanding on December 31 of the preceding calendar year and 195,000 shares, subject to the ability of our Board of Directors to take action to reduce the size of the increase in any given year. Currently, we plan to register the increased number of shares available for issuance under the ESPP each year.employees. Increases in the number of shares available for future grant or purchase may result in additional dilution, which could cause our stock price to decline.

If we are unable to continue to satisfy the applicable continued listing requirements of Nasdaq, our common stock could be delisted.*

Our common stock is currently listed on The Nasdaq Capital Market under the symbol “HTGM.” In order to maintain this listing, we must continue to satisfy minimum financial and other continued listing requirements and standards. There can be no assurance that we will be able to continue to comply with the applicable listing standards. ~~On October 4, 2019,~~ we received a letter from Nasdaq indicating that we are not in compliance with the minimum bid price requirement of Nasdaq Listing Rule 5550(a)(2), which requires that companies listed on The Nasdaq Capital Market maintain a minimum closing bid price of at least $1.00 per share. In March 2020, we requested and received an additional 180-day extension to regain compliance with the $1.00 minimum closing bid price requirement. In August 2020, we obtained stockholder approval at our 2020 annual meeting of authority to implement a reverse stock split at a ratio between 1-for-7 and 1-for-15, inclusive, as determined by our Board of Directors in its sole discretion. We have not yet implemented a reverse stock split and there can be no assurance we will be able to regain compliance with the $1.00 minimum closing bid price requirement or maintain compliance with the other continued listing requirements of the Nasdaq Capital Market.

If we were not able to comply with applicable listing standards, our shares of common stock would be subject to delisting. The delisting of our common stock from trading on Nasdaq may have a material adverse effect on the market for, and liquidity and price of, our common stock and impair our ability to raise capital. Delisting from Nasdaq could also have other negative results, including, without limitation, the potential loss of confidence by customers and employees, the loss of institutional investor interest and fewer business development opportunities. In the event that our common stock is delisted from Nasdaq and is not eligible for quotation or listing on another market or exchange, trading of our common stock could be conducted only in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further.

We do not intend to pay dividends on our common stock in the foreseeable future.

We have never declared or paid any cash dividend on our common stock. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition, our ability to pay cash dividends is currently prohibited by the terms of our debt facility, and any future debt financing arrangement may contain terms prohibiting or limiting the amount of dividends that may be declared or paid on our common stock. Any return to stockholders will therefore be limited to the appreciation of their stock.

Provisions in our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third-party to acquire us or increase the cost of acquiring us, even if doing so would benefit our stockholders or remove our current management.

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders and may prevent attempts by our stockholders to replace or remove our current management. These provisions include:

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our Board of Directors, which is responsible for appointing the members of our management. In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by our Board of Directors. This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by or beneficial to our stockholders. Further, other provisions of Delaware law may also discourage, delay or prevent someone from acquiring us or merging with us.

Our amended and restated certificate of incorporation and amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for certain disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.*

Our amended and restated certificate of incorporation and our amended and restated bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders; (3) any action asserting a claim against us or any of our directors or officers or other employees arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate or our amended and restated bylaws; and/or (4) any action asserting a claim against us or any of our directors or officers or other employees governed by the internal affairs doctrine. The foregoing provisions do not apply to actions brought to enforce a duty or liability created by the Securities Act or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers and other employees. If a court were to find the exclusive forum provision in our governing documents to be inapplicable or unenforceable in an action, we may incur further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

~~General Risk Factors~~Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

If we fail to maintain proper and effective internal controls, our ability to produce accurate consolidated financial statements on a timely basis could be impaired.

We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act and the rules and regulations of The Nasdaq Stock Market (“Nasdaq”). The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements in accordance with ~~U.S. GAAP.~~accounting principles generally accepted in the United States of America (“GAAP”). We have performed system and process evaluation and testing of our internal controls over financial reporting to allow management to report annually on the effectiveness of our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act.

This has required and will require that we incur substantial professional fees and internal costs to augment our accounting and finance functions and that we expend significant management efforts as we continue to make this assessment and ensure maintenance of proper internal controls on an ongoing basis.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we fail to establish and maintain proper and effective internal control over financial reporting, we may not be able to produce timely and accurate consolidated financial statements, and our ability to accurately report our financial results could be adversely affected. If that were to happen, the market price of our stock could decline, and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities.

~~Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.~~

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about our business, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of the analysts who cover us issues an adverse opinion about our company, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

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