Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks and uncertainties. All statements other than statements of historical facts contained in this Quarterly Report on Form 10-Q are forward-looking statements. In some cases, you can identify forward-looking statements by words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” or the negative of these words or other comparable terminology. These forward-looking statements include, but are not limited to, statements about our financial performance, and are subject to a number of risks, uncertainties and assumptions, including those described in this Quarterly Report on Form 10-Q and in “Part I, Item 1A, Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, ~~2018~~2019, as may be updated by “Part II, Item 1A, Risk Factors” of our subsequently filed Quarterly Reports on Form 10-Q, or other filings that we make with the Securities and Exchange Commission, or SEC. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report on Form 10-Q may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance, events or circumstances reflected in the forward-looking statements will be achieved or occur. You should read this Quarterly Report on Form 10-Q, and the documents that we reference herein and have filed with the SEC, with the understanding that our actual future results, levels of activity, performance, and events and circumstances may be materially different from what we expect. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report on Form 10-Q to conform these statements to new information, actual results or to changes in our expectations, except as required by law.

Unless the context otherwise requires, the terms “Quanterix,” the “Company,” “we,” “us” and “our” in this Quarterly Report on Form 10-Q refer to Quanterix Corporation and its subsidiaries. “Quanterix,” “Simoa,” “Simoa HD-X,” “Simoa HD-1,” “SR-X,” ~~“HD-1~~“SP-X,” “HD-X Analyzer,” ~~“SP-X”~~“HD-1 Analyzer” and our logo are our trademarks. All other service marks, trademarks and trade names appearing in this Quarterly Report on Form 10-Q are the property of their respective owners.

Notes to condensed consolidated financial statements

(Unaudited)

1. Organization and operations

Quanterix Corporation (Nasdaq: QTRX) (the Company) is a life sciences company that has developed next generation, ultra-sensitive digital immunoassay platforms that advance precision health for life sciences research and diagnostics. The Company's platforms are based on its proprietary digital "Simoa" detection technology. The Company's Simoa bead-based and planar array platforms enable customers to reliably detect protein biomarkers in extremely low concentrations in blood, serum and other fluids that, in many cases, are undetectable using conventional, analog immunoassay technologies, and also allow researchers to define and validate the function of novel protein biomarkers that are only present in very low concentrations and have been discovered using technologies such as mass spectrometry. These capabilities provide the Company's customers with insight into the role of protein biomarkers in human health that has not been possible with other existing technologies and enable researchers to unlock unique insights into the continuum between health and disease. The Company is currently focusing on protein detection, ~~but~~which it believes is an area of significant unmet need and where it has significant competitive advantages. However, in addition to enabling new applications and insights in protein analysis, the Company’s Simoa platforms have also ~~developing its bead-based technology to detect~~demonstrated applicability across other testing applications, including detection of nucleic acids ~~in biological samples.~~and small molecules.

The Company launched its first immunoassay platform, the Simoa HD-1, in 2014. The HD-1 is a fully automated immunoassay bead-based platform with multiplexing and custom assay capability, and related assay test kits and consumable materials. The Company launched a second bead-based immunoassay platform (SR-X) in the fourth quarter of 2017 with a more compact footprint than the Simoa HD-1 and less automation designed for lower volume requirements while still allowing multiplexing and custom assay capability. The Company initiated an early-access program for its third instrument (SP-X) on the new Simoa planar array platform in January 2019, with the full commercial launch commencing in April 2019. In July 2019, the Company launched the Simoa HD-X, an upgraded version of the Simoa HD-1 which replaces the HD-1. The HD-X has been designed to deliver significant productivity and operational efficiency improvements, as well as greater user flexibility. The Company began shipping and installing HD-X instruments at customer locations in the third quarter of ~~2019, ahead of its original fourth quarter expectation.~~2019. The Company also performs research services on behalf of customers to apply the Simoa technology to specific customer needs. The Company's customers are primarily in the research use only market, which includes academic and governmental research institutions, the research and development laboratories of pharmaceutical manufacturers, contract research organizations, and specialty research laboratories.

The Company acquired Aushon Biosystems, Inc. (Aushon) in January 2018. With the acquisition of Aushon, the Company acquired a CLIA certified laboratory, as well as Aushon's proprietary sensitive planar array detection technology. Leveraging its proprietary sophisticated Simoa image analysis and data analysis algorithms, the Company further refined this planar array technology to develop the SP-X instrument to provide the same Simoa sensitivity found in its bead-based platform.

The Company ~~acquired~~completed the acquisition of UmanDiagnostics AB (Uman), a Swedish company located in Umea, Sweden, ~~(Uman),~~ in August 2019. The acquisition closed with respect to 95% of the outstanding shares of capital stock of Uman on July 1, 2019 and with respect to the remaining 5% of the outstanding shares of capital stock of Uman on August 1, 2019. Uman supplies neurofilament light (Nf-L) antibodies and ELISA kits, which are widely recognized by researchers and biopharmaceutical and diagnostics companies world-wide as the premier solution for the detection of Nf-L to advance the development of therapeutics and diagnostics for neurodegenerative conditions. With the acquisition of Uman, the Company has secured a long-term source of supply for a critical technology.

“At-the-market ~~offering~~offering”

On March 19, 2019, the Company entered into a Sales Agreement (the Sales Agreement) with Cowen and Company, LLC (Cowen) with respect to an ~~at-the-market~~“at-the-market” offering program under which the Company may offer and

Table of Contents

sell, from time to time at its sole discretion, shares of its common stock, par value $0.001 per share, having an aggregate offering price of up to $50.0 million through Cowen as its sales agent.

On June 5, 2019, the Company issued approximately 2.2 million shares of common stock at an average stock price of $22.73 per share pursuant to the terms of the Sales Agreement. The ~~at-the-market~~“at-the-market” offering resulted in gross proceeds of $49.7 million. The Company incurred $1.7 million in issuance costs associated with the ~~at-the-market~~“at-the-market” offering, resulting in net proceeds to the Company of $48.0 million.

On August 6, 2020, the Company delivered written notice to Cowen to terminate the Sales Agreement, which termination the parties agreed to make immediately effective.

Underwritten public ~~offering~~offerings

On August 8, 2019, the Company entered into an underwriting agreement with J.P. Morgan Securities LLC and SVB Leerink LLC, as representatives of the several underwriters, relating to an underwritten public offering of approximately 2.7 million shares of the Company’s common stock, par value $0.001 per share. The underwritten public offering resulted in gross proceeds of $69.0 million. The Company incurred $4.5 million in issuance costs associated with the underwritten public offering, resulting in net proceeds to the Company of $64.5 million.

On August 6, 2020, the Company entered into an underwriting agreement with SVB Leerink LLC and Cowen, as representatives of the several underwriters, relating to an underwritten public offering of approximately 3.0 million shares of the Company’s common stock, par value $0.001 per share. The underwritten public offering resulted in gross proceeds of $97.6 million. The Company incurred $6.2 million in issuance costs associated with the underwritten public offering, resulting in net proceeds to the Company of $91.4 million.

~~Table of Contents~~

for interim financial information and with the instructions to Form ~~10‑Q~~10-Q and Article 10 of Regulation S-X. Accordingly, certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included in ~~our~~the Company’s Annual Report on Form ~~10‑K~~10-K for the year ended December 31, ~~2018~~2019 filed with the Securities and Exchange Commission on March ~~18,~~13, 2020 (the 2019 ~~(the 2018~~ Annual Report on Form 10-K). The consolidated financial information as of December 31, ~~2018~~2019 has been derived from the audited ~~2018~~2019 consolidated financial statements included in the ~~Company’s 2018~~2019 Annual Report on Form ~~10‑K.~~10-K.

2. Significant accounting policies

Principles of consolidation

The condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and include the accounts of Quanterix Corporation and its ~~wholly‑owned~~wholly-owned subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation.

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. In making those estimates and assumptions, the Company bases its estimates on historical experience and on various other assumptions believed to be reasonable. The Company’s significant estimates included in

Table of Contents

the preparation of the consolidated financial statements are related to revenue recognition, fair value of equity instruments and notes receivable, fair value of assets acquired and liabilities assumed in acquisitions, valuation allowances recorded against deferred tax assets, right-of-use assets and ~~stock‑based~~lease liabilities, and stock-based compensation. Actual results could differ from those estimates.

Foreign ~~Currency~~currency

The Company translates assets and liabilities of its foreign subsidiaries at rates in effect at the end of the reporting period. Revenues and expenses are translated at average rates in effect during the reporting period. Translation adjustments are included in accumulated other comprehensive loss.

Income taxes

The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company's consolidated financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on differences between the consolidated financial statement carrying amounts and the tax bases of the assets and liabilities using the enacted tax rates in effect in the years in which the differences are expected to reverse. A valuation allowance against deferred tax assets is recorded if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions in accordance with the provisions of ~~ASC~~Accounting Standards Codification (ASC) 740, Income Taxes (ASC 740). When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. As of September 30, ~~2019~~2020 the Company did not have any significant uncertain tax positions.

During the three months ended September 30, 2019, the Company acquired Uman. The Company analyzed the transaction from an income tax perspective and adjusted the deferred tax assets and liabilities related to the Uman acquisition. Of the total goodwill recorded, less than $0.1 million is amortizable related to the historical tax basis that Uman had prior to the acquisition.

Business combinations

Under the acquisition method of accounting, the Company ~~allocates the fair value of the total consideration transferred to~~generally recognizes the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between willing market participants, are based on estimates and assumptions determined by management. The excess consideration over the aggregate ~~fair~~ value of tangible and intangible assets, net of liabilities assumed, is recorded as goodwill. These valuations require significant estimates and assumptions, especially with respect to intangible assets.

The Company typically uses the discounted cash flow method to value acquired intangible assets. This method requires significant management judgment to forecast future operating results and establish residual growth rates and discount factors. The estimates used to value and amortize intangible assets are consistent with the plans and estimates that are used to manage the business and are based on available historical information and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, the Company could experience impairment charges. In addition, the Company has estimated the economic lives of certain acquired assets and these lives are used to calculate

~~Table of Contents~~

depreciation and amortization expense. If estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed.

Table of Contents

Restricted cash

Restricted cash primarily represents collateral for a letter of credit issued as security for the lease for the Company’s ~~new headquarters.~~headquarters in Billerica, Massachusetts. The restricted cash is long term in nature as the Company will not have access to the funds until more than one year from September 30, ~~2019.~~2020.

Recent accounting pronouncements

The Company is considered to be an “emerging growth company” (EGC) as defined in the Jumpstart Our Business Startups Act of 2012, as amended (JOBS Act). The JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company may remain an EGC until the last day of the fiscal year in which the fifth anniversary of the closing of the initial public offering occurs, although if the market value the Company’s common stock that is held by non-affiliates exceeds $700 million as of any June 30 before that time or if the Company has annual gross revenues of $1.07 billion or more in any fiscal year, the Company would cease to be an EGC as of December 31 of the applicable year. The Company also would cease to be an EGC if it issues more than $1 billion of non-convertible debt over a three-year period. The Company has elected to avail itself of this extended transition period and, as a result, the Company will not be required to adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies so long as the Company remains an ~~emerging growth company.~~EGC.

Recently Adopted

In February 2016, the Financial Accounting Standards Board (FASB) established Topic 842, Leases (ASC 842), by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. ASC 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements (ASU 2018-11). The new standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. An optional transition approach is permitted under ASU 2018-11, applying the new standard to all leases existing at the date of initial application.

On January 1, ~~2019,~~2020, the Company adopted ~~Accounting Standards Codification (ASC) Topic 606,~~ ~~Revenue from Contracts with Customers~~ ~~(ASC 606),~~ASC 842 using the ~~modified retrospective method. Under~~optional transition method allowing entities to recognize a cumulative effect adjustment to the opening balance sheet without restating comparative prior periods presented. ASC ~~606, revenue~~842 requires a lessee to recognize assets and liabilities on the balance sheet for most leases and changes many key definitions, including the definition of a lease. Lessees will continue to differentiate between finance leases and operating, and classification will impact expense recognition.

The Company elected the following practical expedients for all lease asset classes, which must be elected as a package and applied consistently to all of its leases at the transition date: i) the Company did not reassess whether any expired or existing contracts are or contain leases; ii) the Company did not reassess the lease classification for any expired or existing leases (that is, all existing leases that were classified as operating leases in accordance with ASC 840, Leases (ASC 840), are classified as operating leases); and iii) the Company did not reassess initial direct costs for any existing leases.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the facts and circumstances present in the arrangement. Leases with a term greater than one year are recognized ~~upon~~on the ~~transfer~~balance sheet as right-of-use assets and short-term and long-term lease liabilities, as applicable. The Company has elected the practical expedient not to recognize leases on the balance sheet with a term of ~~control~~twelve months or less. The Company’s leases consist of ~~goods or services~~office and lab space and office equipment.

certain to be exercised. Additionally, the Company elected to apply the practical expedient not to separate lease and nonlease components for all leases.

Operating lease liabilities and their corresponding ROU assets are initially recorded based on the present value of lease payments over the expected remaining lease term. The rate implicit in lease contracts is typically not readily determinable and, as a result, the Company utilizes its incremental borrowing rate to discount lease payments, which reflects the fixed rate at which the Company could borrow on a collateralized basis the amount of ~~consideration~~the lease payments, for a similar term, in a similar economic environment.

~~The adoption of ASC 606 is discussed in further detail in Note 3.~~

~~In January of 2019,~~difference between the Company adopted accounting standards update (ASU) 2016-01, which requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. For equity investments without readily determinable fair values that do not qualify for the practical expedient to estimate fair value using the netROU asset value per share or its equivalent, the Company has elected to measure these investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer. This election is made for each investment separately and ~~is reassessed at each reporting period as to whether the investment continues to qualify for this election. Additionally, at each reporting period, the~~

~~Company makes a qualitative assessment considering impairment indicators to evaluate whether the investment is impaired. The adoption of this standard did not have a material effect.~~

~~In February 2016, the FASB issued ASU No. 2016-02,~~ ~~Leases (Topic 842):Recognition and Measurement of Financial Assets and Financial Liabilities~~ ~~(ASU 2016-02)~~, which establishes principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing and uncertainty of cash flows arising from a lease~~. Under ASU 2016-02, lessees will be required to~~ ~~recognize a~~ lease liability primarily attributable to unamortized lease incentives and ~~a right-of-use asset~~deferred rent related to its lease for ~~all leases (with the exception of short term leases)~~its corporate headquarters at the commencement date. ASU 2016-02 is effective for the Company for the year ending December 31, 2020. Early adoption is permitted. In 2018, the FASB modified ASU 2016-02 by issuing ASU 2018-01 and ASU 2018-11, which collectively added two practical expedients, provided a second modified retrospective transition method which does not require retrospective adjustment of prior periods, and provided certain narrow scope improvements to ASU 2016-02. The Company is currently evaluating the expected impact of ASU 2016-2 on its financial statements.900 Middlesex Turnpike in Billerica, Massachusetts (the “900 Middlesex Turnpike Lease”).

~~In June 2016, the FASB issued ASU No. 2016-13,~~ ~~Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments~~ (ASU 2016-13), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. The standard is effective for the Company beginning in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the expected impact of ASU 2016-13 on its financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment. This ASU eliminates Step 2 from the goodwill impairment test. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The Company adopted this ASU on January 1, 2020 with no material effect to its financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). This ASU isremoved the following disclosure requirements: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; and (3) the valuation processes for Level 3 fair value measurements. Additionally, this update added the following disclosure requirements: (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements.

Not Yet Adopted

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. The standard is effective for the Company beginning in the first quarter of 2022, with early adoption permitted.

3. Revenue recognition

The Company recognizes revenue when a customer obtains control of a promised good or service. The amount of revenue recognized reflects consideration that the Company expects to be entitled to receive in exchange for these goods and services, incentives and taxes collected from customers, that are subsequently remitted to governmental authorities.

The Company adopted ~~ASC~~Topic 606,Revenue from Contracts with Customers (ASC 606) on January 1, 2019, using the modified retrospective method for all contracts not completed as of the date of adoption. ~~The reported results for 2019 reflect the application of ASC 606 guidance, while the reported results for 2018 were prepared under ASC 605,~~ ~~Revenue Recognition~~.

Customers

The Company’s customers primarily consist of entities engaged in the life sciences research market that pursue the discovery and development of new drugs for a variety of neurologic, cardiovascular, oncologic and other protein biomarkers associated with diseases. The Company’s customer base ~~exceeds 200 customers and~~ includes several of the largest biopharmaceutical companies, academic research organizations and distributors who serve certain geographic markets.

Product revenue

The Company’s products are composed of analyzer instruments, assay kits and other consumables such as reagents. Products are sold directly to biopharmaceutical and academic research organizations or are sold through distributors in EMEA and Asia Pacific regions. The sales of instruments are generally accompanied by an initial year of implied service-type warranties and may be bundled with assays and other consumables and may also include other items such as training and installation of the instrument and/or an extended service warranty. Revenues from the sale of products are recognized at a point in time when the Company transfers control of the product to the customer, which is upon installation for instruments sold to direct customers, and based upon shipping terms for assay kits and other consumables. Revenue for instruments sold to distributors is generally recognized based upon shipping terms (either upon shipment or delivery).

Service and other revenue

Service revenues are composed of contract research services, initial implied one-year service-type warranties, extended services contracts and other services such as training. Contract research services are provided through the Company’s Accelerator Laboratory and generally consist of fixed fee contracts. Revenues from contract research services are recognized at a point in time when the Company completes and delivers its research report on each

~~Table of Contents~~

individually completed study, or over time if the contractual provisions allow for the collection of transaction consideration for costs incurred plus a reasonable margin through the period of performance of the services. Revenues from service-type warranties are recognized ratably over the contract service period. Revenues from other services are immaterial.

Collaboration and license revenue

The Company may enter into agreements to license the intellectual property and know-how associated with its instruments in exchange for license fees and future royalties (as described below). The license agreements provide the licensee with a right to use the intellectual property with the license fee revenues recognized at a point in time as the underlying license is considered functional intellectual property. The Company ~~has not~~ recognized ~~any~~ revenues from ~~royalties.~~a sales- or usage- based royalties related to the licensing of the Company’s technology and intellectual property.

Payment terms

The Company’s payment terms vary by the type and location of the customer and the products or services offered. Payment from customers is generally required in a term ranging from 30 to 45 days from date of shipment or satisfaction of the performance ~~obligation with no discounts for early payment.~~obligation. The Company does not provide ~~extended payment terms or~~ financing arrangements to its customers.

Table of Contents

The Company’s contracts with customers may include promises to transfer multiple products and services to a customer. The Company combines any performance obligations that are immaterial with one or more other performance obligations that are material to the contract. For arrangements with multiple performance obligations, the Company allocates the contract transaction price, including discounts, to each performance obligation based on its relative standalone selling price. Judgment is required to determine the standalone selling price for each distinct performance obligation. The Company determines standalone selling prices based on prices charged to customers in observable transactions, and uses a range of amounts to estimate standalone selling prices for each performance obligation. The Company may have more than one range of standalone selling price for certain products and services based on the pricing for different customer classes.

Variable consideration in the Company’s contracts primarily relates to (i) sales- and usage-based royalties related to the license of intellectual property in collaboration and license contracts and (ii) certain non-fixed fee research services contracts. ASC 606 provides for an exception to estimating the variable consideration for sales- and usage-based royalties related to the license of intellectual property, such that the sales- orand usage-based royalty will be recognized in the period the underlying transaction occurs. The Company has ~~not~~ recorded ~~any~~ sales- orand usage-based royalty revenue for the three and nine months ended September 30, ~~2019.~~ 2020 related to the intellectual property licensed by the Company. The Company recognizes revenue from sales- and usage-based royalty revenue at the later of when the sale or usage occurs and the satisfaction or partial satisfaction of the performance obligation to which the royalty has been allocated.

The aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied or are partially satisfied as of September 30, 2020 and 2019 is $4.2 million and $5.3 ~~million. Of~~million, respectively. As of September 30, 2020, of the performance obligations not yet satisfied or ~~are~~ partially satisfied, ~~$4.9~~$3.8 million is expected to be recognized as revenue in the next 12 months, with the remainder to be recognized within the 24 months thereafter. The ~~$5.3~~$3.8 million at September 30, 2020 principally consists of ~~$2.8 million~~amounts billed for undelivered services related to initial and extended service-type warranties and research services, as well as ~~$1.7~~$0.5 million related to undelivered licenses of intellectual property for a diagnostics company. During the three and nine months ended September 30, 2020, the Company recognized $1.2 million of previously deferred revenue as a result of entering into a license agreement with a diagnostics company (see Note ~~12)~~13).

Costs to obtain a contract

The Company’s sales commissions are generally based on revenues of the Company. The Company has determined that certain commissions paid under its sales incentive programs meet the requirements to be capitalized as they are incremental and would not have occurred absent a customer contract. The change in the balance of costs to obtain a contract are as follows (in thousands):

The Company has classified the balance of capitalized costs to obtain a contract as a component of prepaid expenses and other current assets ~~as of January 1, 2019 and September 30, 2019~~ and classifies the expense as a component of cost of goods sold and selling, general,

Table of Contents

and administrative expense over the estimated life of the contract. The Company considers potential impairment in these amounts each period.

ASC 606 provides entities with certain practical expedients and accounting policy elections to minimize the cost and burden of adoption.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with original expected length of one year or less and (ii) contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed.

The Company will exclude from its transaction price any amounts collected from customers related to sales and other similar taxes.

When determining the transaction price of a contract, an adjustment is made if payment from a customer occurs either significantly before or significantly after performance, resulting in a significant financing component. The Company does not assess whether a significant financing component exists if the period between when the Company performs its obligations under the contract and when the customer pays is one year or less. None of the Company’s contracts contained a significant financing component as of ~~January 1, 2019 or~~ September 30, ~~2019.~~2020 and 2019, respectively.

The Company has elected to account for the shipping and handling as an activity to fulfill the promise to transfer the product, and therefore will not evaluate whether shipping and handling activities are promised services to its customers.

Grant revenue

The Company has a contract with the National Institutes of Health (NIH) under the Rapid Acceleration of Diagnostics (RADx) program. The Company recognizes revenue from this contract as it performs services under this arrangement when the funding is committed. Revenues and related research and development expenses are presented gross in the consolidated statements of operations as the Company has determined it is the primary obligor under the arrangement relative to the research and development services.

The following table summarizes grant revenue for each period presented (in thousands):

On June 22, 2020, the Company entered into a workplan 1 (WP1) award under NIH’s RADx program to assess the feasibility of a novel SARS-CoV-2 antigen detection test using the Company’s Simoa technology. The Company recognized $1.9 million of grant revenue from the WP1 award during the three and nine months ended September 30, 2020.

On September 29, 2020, the Company entered into a workplan 2 (WP2) contract with NIH under its RADx program. The contract, which has a total award value of $18.2 million, will accelerate the continued development, scale-up, and deployment of the novel SARS-CoV-2 antigen detection test using the Company’s Simoa technology. The contract provides funding to expand assay kit manufacturing capacity and commercial deployment readiness. Release of the $18.2 million of funding under the WP2 contract will be based on the achievement of certain milestones, and there is no assurance that the Company can meet all the milestones on a timely basis, if at all. If the Company does not meet all the milestones, it will not be able access the full $18.2 million in funding under the contract. NaN revenue was recognized related to the WP2 contract during the three and nine months ended September 30, 2020.

For the three months ended September 30, 2020, 101,995 shares of weighted average restricted common stock, restricted stock units, stock options, and warrants were excluded from the calculation of diluted weighted average common shares outstanding as their effect was antidilutive.

For purposes of the diluted net loss per share calculation, unvested restricted common stock, restricted stock units, stock options, and warrants are considered to be potentially dilutive securities, but are excluded from the calculation of diluted net loss per share because their effect would be ~~anti‑dilutive~~anti-dilutive and therefore basic and diluted net loss per share were the same for ~~all periods presented.~~the nine months ended September 30, 2020, and the three and nine months ended September 30, 2019.

The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share for the nine months ended September 30, 2020 and the three and nine months ended September 30, 2019 because to do so would be ~~anti‑dilutive~~anti-dilutive (in common stock equivalent shares):

5. Fair value of financial instruments

ASC Topic 820, Fair Value Measurement (ASC 820), establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable

Table of Contents

inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability, and are developed based on the best information available in the circumstances.

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

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 inputs are inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly; and

Level 3 inputs are unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability.

Fair value measurements as of September 30, ~~2019~~2020 are as follows (in thousands):

7. Investments

During the third quarter of 2016, the Company purchased a minority interest in preferred stock in a privately held company for $0.3 million. During the third quarter of 2018, the Company was issued a convertible note by a privately held company having a principal amount of $0.2 million.

The preferred stock investment is recorded on a cost basis in other non-current assets on the accompanying balance sheets as the Company does not have a controlling interest, does not have the ability to exercise significant influence over the privately held company, and the fair value of the equity investment is not readily determinable. The Company performs an impairment analysis at each reporting period to determine if there is any readily available fair value information that would indicate an impairment. The Company has determined there was no0 impairment during the nine months ended September 30, ~~2019~~2020 or in any prior period.

~~Table of Contents~~

The convertible note is held as an available-for-sale investment, which is carried at fair market value, with the unrealized gains and losses included in the determination of comprehensive income and reporting stockholders equity. Any gains or losses recognized by the Company related to the change in fair value of the convertible note were deemed immaterial. When determining the estimated fair value of the convertible notes, the Company used a commonly accepted valuation methodology.

Equity investments that do not result in consolidation and are not accounted for under the equity method are measured at fair value, with any changes in fair value recognized in net income. For any such investments that do not have readily determinable fair values, the Company elects the measurement alternative to measure the investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.

The 2017 Plan contains an “evergreen” provision, which allows for an annual increase in the number of shares of common stock available for issuance under the 2017 Plan on the first day of each fiscal year during the period beginning in fiscal year 2019 and ending in fiscal year 2027. The annual increase in the number of shares shall be equal to the lowest of: 4% of the number of shares of common stock outstanding as of such date; and an amount determined by the Company’s Board of Directors or Compensation Committee.

Restricted stock

Restricted common stock awards represent shares of common stock issued to employees subject to forfeiture if the vesting conditions are not satisfied. In December 2014, the Company issued 78,912 shares of restricted common stock to a director of the Company under the 2007 Plan. Under the terms of the agreement, shares of common stock issued are subject to a four-year vesting schedule. Vesting occurs periodically at specified time intervals and specified percentages. In January 2015, the Company issued 781,060 shares of restricted common stock to an executive of the Company under the 2007 Plan. The majority of these shares were issued subject to a four-year vesting schedule with 25% vesting on the first anniversary and the remaining vesting 75% ratably on a monthly basis over the remaining three years, while another portion was issued subject to performance based vesting. The vesting of performance based awards is dependent upon achievement of specified financial targets of the Company. The majority of the performance criteria were achieved during the years ended December 31, 2016 and 2015 and the remaining unvested awards with performance conditions are not material. NoNaN restricted common stock awards were granted or vested during the nine months ended September 30, ~~2019.~~2020. As of September 30, 2020, the Company had 39,806 shares of unvested restricted common stock with a weighted average grant date fair value of $3.12 per share.

10. Leases

The Company is a lessee under leases of offices, lab spaces, and ~~$1.1~~certain office equipment. Some of the Company’s leases include options to extend the lease, and these options are included in the lease term to the extent they are reasonably certain to be exercised.

900 Middlesex Turnpike Lease

The Company’s primary lease is the 900 Middlesex Turnpike Lease. On October 2, 2018, the Company entered into a 137-month operating lease for the Company’s new headquarters in Billerica, Massachusetts. The lease is for approximately 92,000 square feet of office and laboratory space and commenced on April 1, 2019. The lease contains a period of free rent and escalating monthly rent payments. As part of the lease, the Company was required to enter into a $1.0 million Letter of Credit drawable by the lessor under specifically outlined conditions, which will be subsequently reduced throughout the lease term. Pursuant to a work letter entered into in connection with the 900 Middlesex Turnpike Lease, the landlord contributed an aggregate of $8.2 million toward the cost of construction and tenant improvements for the building. Under the lease the Company has the option to extend the lease for 2 successive five-year terms, and the renewal options are not reasonably certain to be exercised.

In applying the ASC 842 transition guidance, the 900 Middlesex Turnpike Lease remained classified as an operating lease and the Company recorded ROU assets of $12.2 million and ~~$1.2~~lease liability of $22.8 million on the effective date. The difference between the ROU and the lease liability was driven by the Company derecognizing deferred rent of $3.0 million and the lease obligation incentive of $7.6 million. The Company is recognizing rent expense on a straight-line basis throughout the remaining term of the leases.

48 Tvistevägen

The Company has multiple leases at 48 Tvistevägen Umeå, Sweden for laboratory spaces, manufacturing spaces, and office space (the Uman leases). All of these Uman leases have been assessed as operating leases.

In applying the ASC 842 transition guidance, the Uman leases remained classified as operating leases and the Company recorded ROU assets of less than $0.1 million and lease liability of less than $0.1 million on the effective date. The Company is recognizing rent expense on a straight-line basis throughout the remaining term of the leases.

Tufts University

In June 2007, the Company entered into a license agreement (the License Agreement) for certain intellectual property with Tufts University (Tufts). Tufts is a related party to the Company due to Tufts’ equity ownership in the Company and because a ~~board~~ member of the Company’s Board of Directors was affiliated with Tufts. The License Agreement, which was subsequently amended, is exclusive and ~~sub licensable,~~sublicensable, and will continue in effect on a ~~country by country~~country-by-country basis as long as there is a valid claim of a licensed patent in a country. The Company is committed to pay license and maintenance fees, prior to commercialization, in addition to low single digit royalties on direct sales and services and a royalty on sublicense income. During the three ~~months ended September 30, 2019 and 2018,~~ and nine months ended September 30, ~~2019~~2020 and ~~2018,~~2019, the Company recorded royalty expense of $0.3 million, ~~$0.2~~$0.3 million, ~~$0.7~~$0.8 million, and ~~$0.5~~$0.7 million, respectively, in cost of product revenue on the consolidated statements of operations. During the three and nine months ended September 30, 2020, the Company incurred $1.0 million in cost of collaboration and license revenue owed to Tufts related to sublicensing certain technology and intellectual property to Abbott Laboratories (see Note 13).

Development and supply agreement

Through the Company’s development agreement with STRATEC Biomedical, as amended in December 2016, the parties agreed on additional development services for an additional fee, which is payable when the additional development is completed. A total of $11.7 million is payable to STRATEC upon completion of the development activities. This amount is being recorded to research and development expense and accrued expenses as the services are performed. The initial services were completed during the year ended December 31, 2018. ~~Substantive efforts related to these~~The Company began substantive additional development activities ~~started~~ in the first quarter of 2019. These additional development activities were continued throughout the second of 2019 and ~~were~~ completed in the third quarter of 2019.

The Company’s supply agreement with STRATEC Biomedical requires the Company to purchase a minimum number of commercial units over a ~~seven‑year~~seven-year period ending in May 2021. If the Company were to fail to purchase a required number of commercial units, the Company would be obligated to pay termination costs plus a fee based on the shortfall of commercial units purchased compared to the required minimum amount. Based on the number of commercial instruments purchased as of September 30, ~~2019, assuming no additional commercial units were purchased, this fee would equal $10.3 million. The amount~~2020, the Company ~~could be obligated to pay under the~~has satisfied its required minimum purchase ~~commitment is reduced as each commercial unit is purchased.~~amount per the supply agreement. Also, if the Company terminates the supply agreement under certain circumstances and has not purchased a required number of commercial units, it would be obligated to issue warrants to purchase 93,341 shares of common stock (the Supply Warrants) at $0.003214 per share. The Company believes that it will purchase sufficient units to meet the requirements of the minimum purchase commitment and, therefore, has not accrued for any of the potential cash consideration. The Supply Warrants are accounted for at fair value; however, the fair value of the Supply Warrants as of September 30, ~~2019~~2020 and December 31, ~~2018~~2019 was insignificant as there was a low probability of the warrants being issued.

Legal contingencies

The Company is subject to claims in the ordinary course of business; however, the Company is not currently a party to any pending or threatened litigation, the outcome of which would be expected to have a material adverse effect on its financial condition or the results of its operations. The Company accrues for contingent liabilities to the extent that the liability is probable and estimable.

In exchange for the rights to negotiate an exclusive agreement, the Company received $0.5 million in consideration. As the right to negotiate with the Company has not been executed, the consideration from this agreement is deferred until the sooner of the execution of the contract or the end of the option period. Because the negotiations remain ongoing with respect to the other two fields and the options have not been exercised, the consideration allocated to these options of $1.2 million has been deferred and is recorded as deferred revenue as of September 30, 2019 and December 31, 2018.Abbott License Agreement.

Overview

We are a life sciences company that has developed next generation, ultra-sensitive digital immunoassay platforms that advance precision health for life sciences research and diagnostics. Our platforms are based on our proprietary digital “Simoa” detection technology. Our Simoa bead-based and planar array platforms enable customers to reliably detect protein biomarkers in extremely low concentrations in blood, serum and other fluids that, in many cases, are undetectable using conventional, analog immunoassay technologies, and also allow researchers to define and validate the function of novel protein biomarkers that are only present in very low concentrations and have been discovered using technologies such as mass spectrometry. These capabilities provide our customers with insight into the role of protein biomarkers in human health that has not been possible with other existing technologies and enable researchers to unlock unique insights into the continuum between health and disease. We believe this greater insight will enable the development of novel therapies and diagnostics and facilitate a paradigm shift in healthcare from an emphasis on treatment to a focus on earlier detection, monitoring, prognosis and, ultimately, prevention. We are currently focusing on protein detection, which we believe is an area of significant unmet need and where we have significant competitive advantages. However, in addition to enabling new applications and insights in protein analysis, ~~we are also developing~~ our Simoa ~~bead-based technology to detect~~platforms have also demonstrated applicability across other testing applications, including detection of nucleic acids ~~in biological samples.~~and small molecules.

We currently sell all of our products for life science research, primarily to laboratories associated with academic and governmental research institutions, as well as pharmaceutical, biotechnology and contract research companies, through a direct sales force and support organizations in North America and Europe, and through distributors or sales agents in other select markets, including Australia, Brazil, China, Czech Republic, ~~China,~~ India, Israel, Japan, Lebanon, Mexico, Qatar, Saudi Arabia, Singapore, South Korea ~~Lebanon, Singapore,~~ and Taiwan.

Our instruments are designed to be used either with assays fully developed by us, including all antibodies and supplies required to run the tests, or with “homebrew” kits where we supply some of the components required for testing, and the customer supplies the remaining required elements. Accordingly, our installed instruments generate a recurring revenue stream. We believe that our recurring consumable revenue is driven by our customers’ ability to extract more valuable data using our platform and to process a large number of samples quickly with little hands-on preparation.

We commercially launched our first immunoassay platform, the Simoa HD-1, in January 2014. The HD-1 is based on our bead-based technology, and assays run on the HD-1 are fully automated. We initiated commercial launch of the SR-X instrument in December 2017. The SR-X utilizes the same Simoa bead-based technology and assay kits as the HD-1 in a compact benchtop form with a lower price point, more flexible assay preparation, and a wider range of applications. In July 2019, we launched the Simoa HD-X, an upgraded version of the Simoa HD-1, which replaces the HD-1. The HD-X has been designed to deliver significant productivity and operational efficiency improvements, as well as greater user flexibility. We began shipping and installing HD-X instruments at customer locations in the third quarter of 2019, ahead of our original fourth quarter expectation. As the installed base of the Simoa instruments increases, total

consumables revenue overall is expected to increase. We believe that consumables revenue should be subject to less period-to-period fluctuation than our instrument sales revenue, and will become an increasingly important contributor to our overall revenue.

On January 30, 2018, we acquired Aushon Biosystems, Inc. (Aushon) for $3.2 million in cash, with an additional payment of $0.8 million made in July 2018, six months after the acquisition date. With the acquisition of Aushon, we acquired a CLIA certified laboratory, as well as Aushon’s proprietary sensitive planar array detection technology. Leveraging our proprietary sophisticated Simoa image analysis and data analysis algorithms, we further refined this planar array technology to develop the SP-X instrument to provide the same Simoa sensitivity found in our Simoa bead-based platform. We initiated an early-access program for the SP-X instrument in January 2019, with the full commercial launch commenced in April 2019.

On August 1, 2019, we completed our acquisition of ~~Uman~~UmanDiagnostics AB (Uman) for an aggregate purchase price of $21.2 million, comprised of (i) $15.7 million in cash plus (ii) 191,152 shares of our common stock (representing $5.5 million based on the closing prices of our common stock on the Nasdaq Global Market on July 1, 2019 and August 1, 2019, the dates of issuance). The acquisition closed with respect to 95% of the outstanding shares of capital stock of Uman on July 1, 2019 and with respect to the remaining 5% of the outstanding shares of capital stock of Uman on August 1, 2019. Uman supplies neurofilament light (Nf-L) antibodies and ELISA kits, which are widely recognized by researchers and biopharmaceutical and diagnostics companies world-wide as the premier solution for the detection of Nf-L to advance the development of therapeutics and diagnostics for neurodegenerative conditions.

On September 29, 2020, we entered into a Non-exclusive License Agreement (the Abbott License Agreement) with Abbott Laboratories (Abbott). Pursuant to the terms of the Abbott License Agreement, we granted Abbott a non-exclusive, worldwide, royalty-bearing license, without the right to sublicense, under our bead-based single molecule detection patents in the field of in vitro diagnostics. Abbott has agreed to pay us an initial license fee of $10.0 million in connection with the execution of the Abbott License Agreement, which was recognized as collaboration and license revenue for the three months ended September 30, 2020. In addition, during the three months ended September 30, 2020, we recognized as collaboration and license revenue approximately $1.2 million of previously deferred revenue upon entering into the Abbott License Agreement. Abbott has also agreed to pay us milestone fees subject to the achievement by Abbott of certain development, regulatory and commercialization milestones and low single digit royalties on net sales of licensed products.

We are subject to ongoing uncertainty concerning the SARS-COV-2 pandemic, including its length and severity and its effect on our business. During the first and second quarters, we implemented a resiliency plan focused on the health and safety of our employees and maintaining continuity of our operations. We have seen an impact on instrument revenue due to limitations on our ability to access certain customer sites and complete instrument installations, as well as an impact on consumables revenue from interruptions in certain customer laboratories. We expect these COVID-19 related challenges to continue until these customers return to normal operations.

In view of the pandemic, we have adjusted our operations to expand capacity in our Accelerator Laboratory to support customers whose operations have been disrupted and to sustain clinical trials. We also believe that our cytokine assay technology provides researchers with important and differentiated tools to study disease progression, cytokine release syndrome, and patient-treatment response in the fight against COVID-19. We are working towards developing a SARS-COV-2 quantitative IgG assay, an antigen early detection assay in blood, and a high-definition SARS-COV-2 assay to enable research pursuits. We believe that these activities may provide additional business and revenue opportunities as the situation unfolds. On September 29, 2020, we entered into a workplan 2 (WP2) contract with the National Institute of Health (NIH) under the Rapid Acceleration of Diagnostics (RADx) program. The contract, which has a total award value of $18.2 million, will accelerate the continued development, scale-up and deployment of our novel SARS-CoV-2 antigen test. Initial early feasibility of this test was funded in part through the RADx workplan 1 (WP1) award we were granted in June 2020. We recognized $1.9 million of grant revenue from the WP1 award during the three and nine months ended September 30, 2020. The WP2 contract supports clinical validation of the test in support of planned emergency use authorization (EUA) submissions with the U.S. Food and Drug Administration. The WP2 contract provides funding to expand assay kit manufacturing capacity and commercial deployment readiness. Contract funding is subject to achievement of pre-defined milestones and the

contract period runs through September 2021. Our intention is to make the test available on our high-throughput automated HD-X instrument platform through a network of centralized third-party labs.

The COVID-19 situation remains dynamic and there remains significant uncertainty as to the length and severity of the pandemic, the actions that may be taken by government authorities, the impact to the business of our customers and suppliers, the long-term economic implications and other factors identified in “Part I, Item 1A, Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2019, as may be updated by “Part II, Item 1A, Risk Factors” of our subsequently filed Quarterly Reports on Form 10-Q. We will continue to evaluate the nature and extent of the impact to our business, financial condition, and operating results.

As of September 30, ~~2019,~~2020, we had cash and cash equivalents of ~~$113.3~~$173.2 million. ~~Since~~Other than the third quarter of 2020, since inception, we have incurred net losses. Our net loss was $40.8 million, $31.5 million, ~~$27.0 million,~~ and ~~$23.2~~$27.0 million for the years ended December 31, 2019, 2018 ~~2017~~ and ~~2016,~~2017, respectively, and ~~$29.8~~$21.7 million and ~~$22.2~~$29.8 million for the nine months ended September 30, ~~2019~~2020 and ~~2018,~~2019, respectively. As of September 30, ~~2019,~~2020, we had an accumulated deficit of ~~$205.3~~$238.0 million and stockholders' equity of ~~$136.2~~$209.0 million. We expect to continue to incur significant expenses and operating losses at least through the next 24 months. We expect our expenses will increase substantially as we:

●

expand our sales and marketing efforts to further commercialize our products;

●

strategically acquire companies or technologies that may be complementary to our business;

●

expand our research and development efforts to improve our existing products and develop and launch new products, particularly if any of our products are deemed by the United States Food and Drug Administration, or FDA, to be medical devices or otherwise subject to additional regulation by the FDA;

●

seek premarket approval, or PMA, or 510(k) clearance, or emergency use authorization, or EUA, from the FDA for our existing products or new products if or when we decide to market products for use in the prevention, diagnosis or treatment of a disease or other condition;

●

hire additional personnel and continue to grow our employee headcount;

●

enter into collaboration arrangements, if any, or in-license other products and technologies;

●

expand assay kit manufacturing capacity and commercial development readiness in connection with the RADx WP2 contract;

●

add operational, financial and management information systems; and

●

incur increased costs as a result of operating as a public company.

Table of Contents

primarily due to higher utilization of the Accelerator Laboratory, plus increased personnel costs from the build out of our field service organization. Cost of collaboration and license revenue of $1.0 million resulted from the sublicensing of certain technology and intellectual property to Abbott during the three months ended September 30, 2020. We had no cost of collaboration and license revenue during the three months ended September 30, 2019. Overall cost of goods sold as a percentage of revenue decreased to 33% of total revenue for the three months ended September 30, 2020 as compared to 53% for the three months ended September 30, 2019, ~~from $1.7~~primarily as a result of the significant increase in collaboration and license revenue.

Research and Development Expense

Research and development expense increased by $1.5 million, or 37%, to $5.4 million for the three months ended September 30, ~~2018.~~2020 as compared to $3.9 million for the three months ended September 30, 2019. The increase was primarily due to compensation, development, materials, and other expenses related to work under the RADx WP1 award incurred during the three months ended September 30, 2020.

Selling, General, and Administrative Expense

Selling, general and administrative expense increased by $0.1 million for the three months ended September 30, 2020 as compared to the same period in 2019. The slight increase primarily resulted from headcount additions in various departments as we build out our organization to support future growth, and stock compensation expense.

Interest Income (Expense) and Other Expense, Net

Interest income (expense) and other expense, net decreased by $0.4 million for the three months ended September 30, 2020 as compared to same period in 2019, primarily due to decreased interest income earned on cash equivalents, as COVID-19 unfavorably impacted interest rates on our cash equivalents during the three months ended September 30, 2020.

Income Tax Benefit

Income tax benefit decreased by less than $0.1 million for the three months ended September 30, 2020 as compared to the same period in 2019. The change is primarily due to certain state and international taxes in 2020.

product mix, as well as nine months of costs incurred from the amortization of the Uman acquisition-related inventory valuation adjustment and acquired intangibles during the nine months ended September 30, 2020, as compared to only three months of these costs during the nine months ended September 30, 2019. Cost of service revenue increased to $8.1 million for the nine months ended September 30, 2020 from $6.6 million for the nine months ended September 30, 2019. The increase was primarily due to higher utilization of the Accelerator Laboratory, plus increased personnel costs from the build out of our field service organization. Cost of collaboration and license revenue of $1.0 million resulted from the licensing of certain technology and intellectual property to Abbott during the nine months ended September 30, 2020.

~~Revenue~~

~~Total revenue increased by $14.1 million, or 52.6%, to $40.8~~$0.5 million for the nine months ended September 30, ~~2019~~2020 as compared to ~~$26.8 million for~~ the nine months ended September 30, 2018. Product revenue consisted primarily of sales of instruments totaling $10.3 million and sales of consumables and other products of $18.8 million for the nine months ended September 30, 2019. Product revenue consisted of sales of instruments totaling $6.0 million and sales of consumables and other products totaling $9.9 million for the nine months ended September 30, 2018. The increasesame period in ~~product revenue of $13.2 million was~~2019, primarily due to the ~~sale~~unfavorable impact of ~~more instruments and increased sales of consumables in~~COVID-19 on the nine months ended September 30, 2019. The installed base of instruments increased from September 30, 2018 to September 30, 2019, and as these additional instruments were used by customers, the consumable sales increased. The increase in service and other revenue of $3.1 million was due to increased services performed in our Accelerator Laboratory. We had no collaboration and license revenue in the nine months ended September 30, 2019 as compared to the $2.1 million of revenue related to the collaboration arrangement with bioMérieux in the nine months ended September 30, 2018. We adopted ASC 606 as of January 1, 2019, which did not have a material impact on revenue in the nine months ended September 30, 2019.

~~Table of Contents~~

~~Cost of Goods Sold and Services~~

Cost of product revenue increased by $5.2 million, or 58.1%, to $14.2 million for the nine months ended September 30, 2019 as compared to $9.0 million for the nine months ended September 30, 2018. The increase was primarily due to increased sales of consumables and instruments, along with costs incurred from the amortization of the Uman acquisition-related inventory valuation adjustment and acquired intangibles. Cost of service revenue increased to $6.6 million for the nine months ended September 30, 2019 from $5.0 million for the nine months ended September 30, 2018. The increase was primarily due to higher utilization of the Accelerator Laboratory, plus increased personnel costs from the build outinterest rates of our field service organization. Overall cost of goods sold as a percentage of revenue decreased to 51.1% of total revenue for the nine months ended September 30, 2019 as compared to 52.4% for the nine months ended September 30, 2018, primarily as a result of decreased costs to produce products.

~~Research and Development Expense~~

Research and development expense increased slightly by less than $0.1 million, or 0.3%, for the nine months ended September 30, 2019 as compared to the nine months ended September 30, 2018. The increase was primarily due to the development of the SP-X and HD-X and the increased headcount in research and development.

~~Selling, General and Administrative Expense~~

Selling, general and administrative expense increased by $15.2 million, or 65.6%, to $38.3 million for the nine months ended September 30, 2019 as compared to $23.1 million for the nine months ended September 30, 2018. The increase was primarily due to headcount additions in various departments as we build out our organization to support future growth, the lease for the new headquarters, and stock compensation expense. In addition, we incurred approximately $1.9 million in costs associated with the acquisition of Umancash equivalents during the nine months ended September 30, ~~2019.~~2020.

~~Interest~~ Income ~~and Other Expense, Net~~Tax Benefit

~~Interest income and other expense, net increased by~~Income tax benefit was $0.3 million for the nine months ended September 30, ~~2019~~2020 as compared to $0.1 million for the same period in ~~2018,~~2019. The change is primarily due to ~~the interest income earned on cash equivalents, which increased due to the at-the-market~~certain state and ~~underwritten public offerings completed during 2019.~~international taxes in 2020.

Liquidity and Capital Resources

To date, we have financed our operations principally through equity offerings, borrowings from credit facilities and revenue from our commercial operations.

Equity Offerings

In December 2017, we completed our ~~IPO~~initial public offering (IPO) in which we sold 4,916,480 shares of common stock at ~~an initial public offering~~a price of $15.00 per share. The aggregate net proceeds received by us from the offering, net of underwriting discounts and commissions and offering expenses, were $65.6 million. Prior to the IPO, we had raised capital through the sale of redeemable convertible preferred stock in private placement transactions.

On March 19, 2019, we entered into a Sales Agreement for an “at the market offering” arrangement with Cowen and Company, LLC (Cowen), which allows us to issue and sell shares of common stock pursuant to a shelf registration statement for total gross sales proceeds of up to $50.0 million from time to time through Cowen, acting as our agent. During the ~~nine months ended September 30,~~ 2019 fiscal year, we sold an aggregate of 2,186,163 shares of common stock pursuant to this

Table of Contents

agreement resulting in $49.7 million in gross proceeds and $48.0 million in net proceeds.On August 6, 2020, we delivered written notice to Cowen to terminate the Sales Agreement, which termination the parties agreed to make immediately effective.

On August 8, 2019, we entered into an underwriting agreement with J.P. Morgan Securities LLC and SVB Leerink LLC, as representatives of the several underwriters, relating to an underwritten public offering of 2,732,673 shares of common stock at a public offering price of $25.25 per share. We received $69.0 million in gross proceeds and $64.5 million in net proceeds.

On August 6, 2020, we entered into an underwriting agreement with SVB Leerink LLC and Cowen, as representatives of the several underwriters, relating to an underwritten public offering of approximately 3.0 million shares of common stock, par value $0.001 per share. The underwritten public offering resulted in gross proceeds of $97.6 million. We incurred $6.2 million in issuance costs associated with the underwritten public offering, resulting in net proceeds of $91.4 million.

Loan Facility with Hercules

On April 14, 2014, we executed a ~~Loan Agreement~~loan agreement with Hercules Capital, Inc. ~~(formerly known as Hercules Technology Growth Capital, Inc.)~~(Hercules). The ~~Loan Agreement~~loan agreement provided a total debt facility of $10.0 million, which is secured by substantially all of our assets. At closing, we borrowed $5.0 million in principal and had the ability to draw the additional $5.0 million over the period from November 1, 2014 to March 31, 2015. The interest rate on this term loan was variable based on a calculation of 8% plus the prime rate less 5.25%, with a minimum interest rate of 8%. Interest was to be paid monthly beginning the month following the borrowing date. Principal payments were scheduled to begin on September 1, 2015, unless we achieved certain milestones which would have extended this date to December 1, 2015 or March 1, 2016. In connection with the execution of the ~~Loan Agreement,~~loan agreement, we issued Hercules a warrant to purchase up to 173,428 shares of our Series C Preferred Stock at an exercise price of $3.3299 per share. Upon closing of the IPO, this warrant was automatically converted into a warrant to purchase up to 53,960 shares of our common stock at an exercise price of $10.70 per share.

~~Table of Contents~~

On March 4, 2015, we executed Amendment 1 to the ~~Loan Agreement~~loan agreement and drew the additional $5.0 million available under the ~~Loan Agreement~~loan agreement at that time. The terms of the amendment deferred principal payments to start on December 1, 2015 or March 1, 2016 if we obtained at least $10.0 million in equity financing before December 1, 2015. This equity financing did not occur before December 1, 2015.

In January 2016, we executed Amendment 2 to the ~~Loan Agreement,~~loan agreement, which increased the total facility available by $5.0 million to a total of $15.0 million and further delayed the start of principal payments to July 1, 2016. Following the Series D Preferred Stock financing in March 2016, we could have elected to further delay the start of principal payments until January 1, 2017, however we voluntarily began paying principal on July 1, 2016. Upon signing this amendment, we drew an additional $3.0 million under the debt facility. The remaining $2.0 million available for borrowing expired unused in 2016, decreasing the amounts available under the debt facility to $13.0 million.

In March 2017, we signed Amendment 3 to the ~~Loan Agreement~~loan agreement increasing the total facility available by $5.0 million to a total of $18.0 million. We did not draw any of this additional amount, which was available for us to draw until February 28, 2018. Additionally, we did not request an optional term loan for an incremental $5.0 million which was available for us to request until September 3, 2018. Principal payments were delayed to September 1, 2018 and the loan maturity date was extended to March 1, 2019. We voluntarily made principal payments in the months of March, April, and May 2018. No principal payments were made in June, July or August 2018. The amendment did not affect the due date of the existing end of term fees (in aggregate $0.5 million) which were due on February 1, 2018. In connection with this amendment, we issued Hercules a warrant to purchase up to 38,828 shares of our Series D Preferred Stock at an exercise price of $3.67 per share. Upon closing of the IPO, this warrant was automatically converted into a warrant to purchase up to 12,080 shares of our common stock at an exercise price of $11.80 per share.

Table of Contents

In July 2017, we signed Amendment 4 to the ~~Loan Agreement,~~loan agreement, which capped the "Term Loan Interest Rate" with respect to the 2017 Term Loan Advance only at 10%. Amendment 4 to the ~~Loan Agreement~~loan agreement did not change or affect any other element of the ~~Loan Agreement~~loan agreement or the Term Loan Advance.

In August 2018, we signed Amendment 5 to the ~~Loan Agreement,~~loan agreement, which extends the interest only payment period through March 1, 2020 and also extends the loan maturity date to March 1, 2020. We accounted for the August 2018 amendment as a modification pursuant to ~~ASC 470-50~~Accounting Standards Codification (ASC) 470, Debt (ASC 470) and determined that no material change occurred as a result of the modification. In addition, the amendment deferred the payment of principal until the maturity date. $0.1 million of end of term payments ~~are due~~were paid in March 2020.

In October 2018, we signed Amendment 6 to the ~~Loan Agreement,~~loan agreement, which amends the ~~Loan Agreement's~~loan agreement's collateral clause to exclude the $1 million certificate of deposit associated with the lease on our new headquarters in Billerica, Massachusetts. The ~~Loan Agreement~~loan agreement and amendments contain end of term payments and are recorded in the debt accounts. $0.5 million of end of term payments were paid in the year ended December 31, 2018.

On April 15, 2019, we ~~entered into~~signed Amendment ~~No.~~ 7 to the ~~Loan Agreement,~~loan agreement, which extends the interest only payment period through July 1, 2021 and also extends the loan maturity date to October 1, 2021. We are required to pay the loan principal in five equal installments starting July 1, 2021 with the final principal payment to be made on October 1, 2021.

On July 2, 2019, 66,041 warrants were exercised by Hercules on a net, non-cash, basis. Per the terms of the warrant agreement, we issued 45,690 shares of common stock with a value equal to Hercules’ gain.

The ~~Loan Agreement~~loan agreement contains negative covenants restricting our activities, including limitations on dispositions, mergers or acquisitions, incurring indebtedness or liens, paying dividends or making investments and certain other business transactions. There are no financial covenants associated with the ~~Loan Agreement.~~loan agreement. The obligations under the ~~Loan Agreement~~loan agreement are subject to acceleration upon the occurrence of specified events of default, including a material adverse change in our business, operations or financial or other condition, which is subjective in nature. We have determined that the risk of subjective acceleration under the material adverse events clause is not probable and therefore have classified the outstanding principal in current and long-term liabilities based on scheduled principal payments.

Uman Acquisition

In August 2019, we completed the acquisition of Uman, in which we paid $15.7 million in cash to the shareholders of Uman. We funded this payment through our existing cash balances. In addition, we issued $5.5 million in stock in connection with the purchase of Uman. The acquisition closed with respect to 95% of the outstanding shares of capital stock of Uman on July 1, 2019 and with respect to the remaining 5% of the outstanding shares of capital stock of Uman on August 1, 2019.

Net Cash Used in Operating Activities

We derive cash flows from operations primarily from the sale of our products and services. Our cash flows from operating activities are also significantly influenced by our use of cash for operating expenses to support the growth of our business. We have historically experienced negative cash flows from operating activities as we have developed our technology, expanded our business and built our infrastructure and this may continue in the future.

Net cash used in operating activities was $28.0 million during the nine months ended September 30, 2020. The net cash used in operating activities primarily consisted of the net loss of $21.7 million offset by non-cash charges of $7.0 million of stock-based compensation expense and $3.2 million of depreciation and amortization expense. Cash used as a result of changes in operating assets and liabilities of $17.5 million was primarily due to an increase in accounts receivable of $15.4 million, and an increase in inventory of $3.5 million.

Net cash used in operating activities was $21.7 million during the nine months ended September 30, 2019. The net cash used in operating activities primarily consisted of the net loss of $29.8 million offset by non-cash charges of $4.7 million of stock-based compensation expense and $2.2 million of depreciation and amortization expense. Cash used as a result of changes in operating assets and liabilities of $1.2 million was primarily due to a $10.1 million increase in other non-current liabilities related to our new lease, offset by an increase in accounts receivable of $4.5 million, and an increase in inventory of $3.9 million.

Net cash used in operating activities was $20.6 million during the nine months ended September 30, 2018. Net cash used in operating activities primarily consisted of the net loss of $22.2 million, and an increase in accounts payable and accrued expenses of $0.1 million. Other cash outflows including a decrease in inventory of $1.0 million, an increase of prepaid and other expenses of $1.0 million and a decrease in deferred revenue of $2.5 million are primarily offset by a decrease in accounts receivable of $1.2 million, an increase in non-cash stock compensation expense of $3.4 million, and an increase in other non-cash adjustments of $1.2 million.

Net Cash Used in Investing Activities

Historically, our primary investing activities have consisted of capital expenditures for the purchase of capital equipment to support our expanding infrastructure and work force. We expect to continue to incur additional costs for capital expenditures related to these efforts in future periods.

We used $2.1 million of cash in investing activities during the nine months ended September 30, 2020 for the purchase of property and equipment.

We used $24.8 million of cash in investing activities during the nine months ended September 30, 2019. The significant increase was related to the cash portion of the Uman acquisition, as well as the leasehold improvements for our new headquarters, which is a component of our lease ~~agreement.~~

~~We used $5.3 million of cash in investing activities during~~agreement for the nine months ended September 30, ~~2018 consisting of cash paid in the acquisition of Aushon, net of cash acquired, and for purchases of capital equipment to support our infrastructure.~~ 2019.

Net Cash Provided by ~~(Used in)~~ Financing Activities

Historically, we have financed our operations principally through private placements of our convertible preferred stock and borrowings from credit facilities, the sale of shares of our common stock in our IPO and revenues from our commercial operations.

Financing activities provided $94.2 million of cash during the nine months ended September 30, 2020, primarily from $91.4 million in net proceeds from our underwritten public offering during the third quarter of 2020, and $1.9 million in proceeds from common stock option exercises.

Table of Contents

Financing activities provided $115.5 million of cash during the nine months ended September 30, 2019, primarily from proceeds of our “at-the-market” offering during the second quarter of 2019 and our underwritten public offering during the third quarter of 2019.

~~We used $1.3 million~~

Capital Resources

Other than the third quarter of cash in financing activities during the nine months ended September 30, 2018, which was primarily used in payments of outstanding debt of $1.9 million, partially offset by proceeds of common stock option exercises of $0.7 million.

~~Capital Resources~~

We2020, since inception, we have ~~not achieved profitability on a quarterly or annual basis since our inception, and we expect to continue to incur~~incurred net losses, ~~in the future. We~~and we also expect that our operating expenses will increase as we continue to increase our marketing efforts to drive adoption of our commercial products. Additionally, as a public company, we have incurred and will continue to incur significant audit, legal and other expenses that we did not incur as a private company. Our liquidity requirements have historically consisted, and we expect that they will continue to consist, of sales and marketing expenses, research and development expenses, working capital, debt service and general corporate expenses.

We believe cash generated from commercial sales, our current cash and cash equivalents, and interest income we earn on these balances will be sufficient to meet our anticipated operating cash requirements for at least the next 12 months. In the future, we expect our operating and capital expenditures to increase as we increase headcount, expand our

~~Table of Contents~~

sales and marketing activities and grow our customer base. Our estimates of the period of time through which our financial resources will be adequate to support our operations and the costs to support research and development and our sales and marketing activities are forward-looking statements and involve risks and uncertainties and actual results could vary materially and negatively as a result of a number of factors, including the factors discussed in Item 1A, "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, ~~2018.~~2019, as may be updated by “Part II, Item 1A, Risk Factors” of our subsequently filed Quarterly Reports on Form 10-Q. We have based our estimates on assumptions that may prove to be wrong and we could utilize our available capital resources sooner than we currently expect. Our future funding requirements will depend on many factors, including:

●

market acceptance of our products, including our SP-X and HD-X instruments;

●

the cost and timing of establishing additional sales, marketing and distribution capabilities;

●

the cost of our research and development activities;

●

our ability to enter into collaborations in the future, and the success of any such collaborations;

●

the cost and timing of potential regulatory clearances or approvals that may be required in the future for our products;

●

the effects of the COVID-19 pandemic; and

●

the effect of competing technological and market developments.

If the conditions for raising capital are favorable, we may seek to finance future cash needs through public or private equity or debt offerings or other financings. ~~On March 19, 2019,~~However, we filed a universal shelf registration statement on Form S-3, which was declared effective by the SEC on May 10, 2019, and pursuant to which we registered for sale up to $200 million of any combination of our common stock, preferred stock, debt securities, warrants, rights, and/or units from time to time and at prices and on terms that we may determine. After the sales of shares of common stock in our “at-the-market” offering during June 2019, and the sale of 2,732,673 shares of common stock in our underwritten public offering in August 2019, approximately $81.3 million of securities remained available for issuance under this shelf registration statement. This registration statement will remain in effect up to May 10, 2022. We cannot assure you that we will be able to obtain additional funds on acceptable terms, or at all. If we raise additional funds by issuing equity or equity-linked securities, our stockholders may experience dilution. Future debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt or equity financing 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, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us. If we do not have or are not able to obtain sufficient funds, we may have to delay development or commercialization of our products.

Critical Accounting Policies, Significant ~~Judgements~~Judgments and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or U.S. GAAP, requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of assets and liabilities in our financial statements and accompanying notes. The most significant assumptions used in the financial statements are the underlying assumptions used in revenue recognition and stock-compensation. We base estimates and assumptions on historical experience when available and on various factors that we determined to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies and significant estimates that involve a higher degree of judgment and complexity are described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies, Significant ~~Judgements~~Judgments and Estimates” included in our Annual Report on Form 10-K for the year ended December 31, ~~2018.~~2019. There have been no material changes to our critical accounting policies and estimates as disclosed therein, with the exception of our adoption of recent accounting pronouncements, as discussed below.

Recent Accounting Pronouncements

We adopted ~~ASC 606, “Revenue Recognition — Revenue from Contracts with Customers~~”the Financial Accounting Standards Board (FASB) established Topic 842, Leases and its related ~~amendment.~~amendments. See Notes 2 and 310 to our unaudited financial statements included elsewhere in this Quarterly Report on Form 10-Q for more information.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

At September 30, ~~2019,~~2020, there have been no material changes to the market risk information described under “Quantitative and Qualitative Disclosures About Market Risk” included in the Annual Report on Form 10-K for the year ended December 31, ~~2018.~~2019.

Item 4. Controls and Procedures

(a)Evaluation of Disclosure Controls and Procedures. Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules ~~13a‑15(e)~~ 13a-15(e)and ~~15d‑15(e)~~15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act) as of the end of the period covered by this Quarterly Report on Form ~~10‑Q,~~10-Q, have concluded that, based on such evaluation, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the ~~SEC’s~~SEC’s rulesand forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b)Changes in Internal Control over Financial Reporting. There were no changes in our internal control over financial reporting identified in connection with the evaluation of such internal control that occurred during the three months ended September30, ~~2019~~2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1. Legal Proceedings

We are not currently a party to any material legal proceedings.

Item 1A. Risk Factors

There have been no material changes to the risk factors described in our Annual Report on Form 10-K for the year ended December 31, ~~2018,~~2019, filed with the SEC on March ~~18, 2019, except~~13, 2020, as ~~set forth in~~updated by “Part II, Item 1A, Risk Factors” of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, except for the addition of the following risk factor:

Our WP2 contract with NIH under the RADx program could expose us to unique risks and costs.

NIH launched the RADx program to expedite development, commercialization, and implementation of technologies for COVID-19 testing to help increase testing in the United States. On September 29, 2020, we entered into a WP2 contract with NIH under the RADx program. The contract, which has a total award value of $18.2 million, will accelerate the continued development, scale-up and deployment of our novel SARS-CoV-2 antigen test. Initial early feasibility of this test was funded in part through the RADx WP1 award we were granted in June ~~30, 2019, as filed~~2020. The contract provides funding to expand assay kit manufacturing capacity and commercial deployment readiness. Release of the $18.2 million of funding under the WP2 contract will be based on the achievement of certain milestones, and there is no assurance that we can meet all the milestones on a timely basis, if at all. If we do not meet all the milestones, we will not be able access the full $18.2 million in funding under the contract.

In addition, other factors that could materially adversely affect our revenue stemming from the WP2 contract include:

●

budgetary constraints affecting U.S. government spending generally, or NIH in particular;

●

changes in U.S. government or NIH fiscal policies or available funding, including due to Congressional appropriations;

●

changes in U.S. government or NIH programs, requirements or priorities;

●

adoption of new laws or regulations;

●

technological developments;

●

U.S. government shutdowns, threatened shutdowns or budget delays;

●

competition and consolidation in our industry; and

●

general economic conditions.

These or other factors could cause NIH to reduce its funding or future activities under the WP2 contract which could have a material adverse effect on the revenue generated by this contract.

The WP2 contract also contains certain provisions from the Federal Acquisition Regulations (FAR), some of which are customary or legally required, that give the U.S. government substantial rights and remedies, many of which are not typically found in commercial contracts. For example, the WP2 contract contains provisions permitting unilateral termination or modification, in whole or in part, at the U.S. government’s convenience. In addition, the WP2 contract contains additional requirements that may increase our costs of doing business, reduce our profits, and expose us to liability for failure to comply with these terms and conditions. These requirements include, mandatory internal control systems and policies, mandatory socioeconomic compliance requirements, environmental compliance requirements and intellectual property provisions. If we fail to maintain compliance with these requirements, we may be subject to potential contract or False Claims Act liability and to termination of the contract.

Table of Contents

In addition, we may be required to enter into agreements with third parties, including suppliers, consultants and other third-party contractors in order to satisfy our contractual obligations pursuant to this contract with NIH. Negotiating and entering into such arrangements can be time-consuming and we may not be able to reach agreement with such third parties. Any such agreement must also be compliant with the ~~SEC on August 6, 2019.~~terms of the WP2 contract. Any delay or inability to enter into such arrangements or entering into such arrangements in a manner that is non-compliant with the terms of our contract, may result in violations of our contract and/or delays in the release of funding.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Not applicable.

~~Unregistered Sales of Equity Securities~~

~~On July 2, 2019, 66,041 warrants were exercised by Hercules on a net, non-cash, basis. Per the terms of the warrant agreement, we issued 45,690 shares of common stock. The shares were issued~~ in a private placement exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, or the Securities Act, and Rule 506(b) of Regulation D promulgated thereunder, because the offer and sale of the shares did not involve a “public offering” as defined in Section 4(a)(2) of the Securities Act, and other applicable requirements were met.

~~See also Current Reports on Form 8-K filed with the SEC on July 2, 2019 and August 2, 2019.~~

~~Use of Proceeds from Initial Public Offering of Common Stock~~

On December 11, 2017, we completed the initial public offering of our common stock, which resulted in the sale of 4,916,480 shares, including 641,280 shares sold by us pursuant to the exercise in full by the underwriters of their option to purchase additional shares in connection with the initial public offering, at a price to the public of $15.00 per share. The offer and sale of all of the shares in our initial public offering was registered under the Securities Act pursuant to a registration statement on Form S-1 (File No. 333-221475), which was declared effective by the SEC on December 6, 2017, and a registration statement on Form S-1 (File No. 333-221932) under Rule 462(b) of the Securities Act that became effective upon its filing. Following the sale of all of the shares in connection with the closing of our initial public offering, the offering terminated. J.P. Morgan Securities LLC, Leerink Partners LLC and Cowen and Company, LLC acted as joint book-running managers for the initial public offering. BTIG, LLC and Evercore Group L.L.C. acted as co-managers.

We received approximately $65.6 million in net proceeds after deducting underwriting discounts and commissions and offering costs payable by us. As of September 30, 2019, we had used all of the net proceeds from the offering for: operating expenses, capital investments, debt payments and the acquisition of Aushon. None of the offering expenses consisted of direct or indirect payments made by us to directors, officers or persons owning 10% or more of our common stock or to their associates, or to our affiliates, and we have not used any of the net proceeds from the offering to make payments, directly or indirectly, to any such persons. There has been no material change in the planned use of the net proceeds from our initial public offering as described in our final prospectus filed with the SEC on December 7, 2017 pursuant to Rule 424(b)(4) under the Securities Act.
