NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements (within the meaning of the U.S. Private Securities Litigation Reform Act of 1995) 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, forward-looking statements can be identified 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 related to our financial performance, and are subject to a number of risks, uncertainties, and assumptions, including those further described elsewhere in this Quarterly Report on Form 10-Q, in the section titled “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 6, 2023, or in other filings that we make with the 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 us 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.

Readers should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in any forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance, or events and circumstances reflected in forward-looking statements will be achieved or occur. 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.

Readers should read this Quarterly Report on Form 10-Q and any documents referenced herein that we have filed with the SEC as exhibits to this Quarterly Report on Form 10-Q with the understanding that our actual future results, levels of activity, performance, and events and circumstances may be materially different from what we expect.

Service Marks, Trademarks and Trade Names

Unless the context otherwise requires, the terms “Quanterix,” the “Company,” “we,” “it,” “us,” and “our” in this Quarterly Report on Form 10-Q refer to Quanterix Corporation and its consolidated subsidiaries. “Quanterix,” “Simoa,” “Simoa HD-X,” “Simoa HD-1,” “SR-X,” “SP-X,” “HD-X,” 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. We do not intend our use or display of other companies’ trade names, trademarks, or service marks to imply a relationship with, endorsement, or sponsorship of us by these other companies.

QUANTERIX CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1. Organization and Nature of Business

Quanterix Corporation (“Quanterix” or 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. The Company is currently focusing on protein detection, but its Simoa platforms have also demonstrated applicability across other testing applications, including detection of nucleic acids and small molecules.

The Company also provides contract research services for customers through its CLIA-certified Accelerator Laboratory. The Accelerator Laboratory provides customers with access to Simoa technology and supports multiple projects and services, including sample testing, homebrew assay development, and custom assay development. To date, the Company has completed over 2,000 projects for more than 450 customers from all over the world using its Simoa platforms.

Note 2. Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with the generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting on Form 10-Q. Accordingly, certain information and disclosures required for complete financial statements prepared in accordance with U.S. GAAP are not included herein. The Consolidated Balance Sheet included herein was derived from the audited Consolidated Financial Statements as of December 31, 2022, but does not include all disclosures required by U.S. GAAP on an annual reporting basis. Certain prior period amounts have been reclassified to conform to the current period presentation.

These Consolidated Financial Statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 6, 2023. Since the date of that filing, there have been no changes or updates to the Company’s significant accounting policies, other than those described below.

In the opinion of management, the Consolidated Financial Statements contain all normal, recurring adjustments necessary for a fair statement of financial position, results of operations, comprehensive loss, and cash flows as of the dates and for the interim periods presented. The results of operations for the three and six months ended June 30, 2023 may not be indicative of the results for the full fiscal year ended December 31, 2023 or any other period.

The Company’s fiscal year is the twelve-month period from January 1 through December 31.

Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues, and expenses reported and disclosures in the financial statements and accompanying notes. Such estimates include, but are not limited to, revenue recognition, valuation of inventory, leases, valuation of intangible and other long-lived assets, recoverability of deferred tax assets, ongoing impairment reviews, and stock-based compensation expense. The Company bases its estimates on historical experience, known trends, market specific information, or other relevant factors it believes to be reasonable.

9

On an ongoing basis, management evaluates its estimates and changes in estimates are recorded in the period in which they become known. Actual results may differ from these estimates.

Foreign Currency

             The functional currency of the Company’s subsidiaries is their respective local currencies. These subsidiary financial statements are translated into U.S. dollars using the period-end exchange rates for assets and liabilities, average exchange rates during the corresponding period for revenue and expenses, and historical rates for equity. The effects of foreign currency translation adjustments are recorded in accumulated other comprehensive loss within stockholders’ equity on the Consolidated Balance Sheets.

               Foreign currency transaction gains (losses) are included in other income (expense), net on the Consolidated Statements of Operations. Foreign exchange losses were not material during the six months ended June 30, 2023, and were $0.4 million during the six months ended 2022.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Quanterix and its wholly-owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

In accordance with Accounting Standards Codification (“ASC”) 810 – Consolidation, the Company assesses the terms of its investment interests in entities to determine if any meet the definition of a variable interest entity (“VIE”) and require consolidation into its Consolidated Financial Statements. Refer to Note 15 –Variable Interest Entities for further discussion.

Presentation of Restricted Cash

The following table summarizes the period ending cash and cash equivalents as presented on the Consolidated Balance Sheets and the total cash, cash equivalents, and restricted cash as presented on the Consolidated Statements of Cash Flows (in thousands):

	As of June 30,
	2023		2022
Cash and cash equivalents	$	329,525	$	361,293
Restricted cash (1)		2,686		2,594
Cash, cash equivalents, and restricted cash	$	332,211	$	363,887

(1) Restricted cash consists of collateral for a letter of credit issued as security for several of the Company’s leased facilities and to secure the Company’s corporate credit card program. The short-term or long-term classification is determined in accordance with the expiration of the underlying letter of credit and security.

Recent Accounting Pronouncements

There are no new accounting pronouncements issued or effective in the current or future periods that are expected to have a material impact on the Company’s Consolidated Financial Statements or accompanying notes.

Product Revenue

UltraDx

On May 26, 2022, the Company and UltraDx Limited (“UltraDx”), a company formed by ARCH Venture Partners (“ARCH”), entered into an agreement (the “UltraDx Agreement). Under the UltraDx Agreement, the Company agreed to supply UltraDx with HD-X instruments (both fully assembled and disassembled), assays and assay

11

components, and granted a co-exclusive license to manufacture, seek Chinese regulatory approval of (including performance of any necessary research and development activities), and commercialize, HD-X instruments assembled in China and related assays in the Chinese neurological in vitro diagnostic market. Refer to Note 13 – Related Party Transactions for a discussion of the related party relationships between Quanterix and these entities.

The Company determined that the instruments, components, and licenses formed a single, combined performance obligation. The consideration due to the Company included (1) cash proceeds of $1.9 million, which was received and recognized as revenue in the third quarter of 2022 when the instruments, components, and licenses were delivered to and paid by UltraDx, and (2) contingent, non-cash consideration in the form of ordinary shares of UltraDx with a deemed fair value of $1.0 million. The issuance of the shares was contingent on UltraDx completing a preferred share financing under the terms and conditions in the UltraDx Agreement. Given the uncertainty of the completion of the preferred share financing, the Company concluded that the non-cash consideration related to the ordinary shares was variable consideration that was fully constrained at contract inception.

During the three months ended June 30, 2023, UltraDx completed the qualified preferred share financing and issued to the Company one million ordinary shares with a total fair value of $1.0 million. Refer to Note 5 – Fair Value of Financial Instruments for the Company’s disclosures related to determining the fair value of the shares received. Also refer to Note 15 – Variable Interest Entities for additional information on the Company’s investment interests in UltraDx as a result of the share issuance.

During the three and six months ended June 30, 2023, the Company recognized $1.4 million of revenue, which includes the one-time revenue from the receipt of the UltraDx shares. During the three and six months ended June 30, 2022, no revenue was recognized under the UltraDx Agreement.

Service Revenue

Eli Lilly and Company

On February 25, 2022, the Company entered into a Master Collaboration Agreement with Eli Lilly and Company (“Lilly”) establishing a framework for future projects focused on the development of Simoa immunoassays (the “Lilly Collaboration Agreement”). The Company also entered into a statement of work under the Lilly Collaboration Agreement to perform assay research and development services within the field of Alzheimer’s disease. In connection with the Lilly Collaboration Agreement, the Company received a non-refundable up-front payment of $5.0 million during the first quarter of 2022, which was recognized over a one-year period. In addition, under the statement of work, the Company receives $1.5 million per calendar quarter, which began in the first quarter of 2022. The statement of work automatically renews on a quarterly basis until Lilly provides a termination notice in accordance with the terms of the Lilly Collaboration Agreement. As of June 30, 2023, the Lilly Collaboration Agreement and the statement of work were still in effect.

Concurrent with the execution of the Lilly Collaboration Agreement, the Company entered into a Technology License Agreement (the “Lilly License”) under which Lilly granted the Company a non-exclusive license to Lilly’s proprietary pTau217 antibody technology for use in research use only products and services and future in vitro diagnostics applications within the field of Alzheimer’s disease. In consideration of the Lilly License, the Company paid an upfront fee, is required to make milestone payments based on the achievement of predetermined regulatory and commercial events, and will pay royalties on net sales of licensed products.

The Company recognized revenue from the Lilly Collaboration Agreement of $1.5 million and $3.0 million during the three and six months ended June 30, 2023, respectively, and $2.7 million and $5.4 million during the three and six months ended June 30, 2022, respectively.

Collaboration and License Revenue

Abbott Laboratories

On September 29, 2020, the Company and Abbott Laboratories (“Abbott”) entered into a Non-Exclusive License Agreement (the “Abbott License Agreement”). Under the terms of the Abbott License Agreement, the Company granted Abbott a non-exclusive, worldwide, royalty-bearing license, without the right to sublicense, under the Company’s bead-based single molecule detection patent (the “Licensed Patents”) in the field of in vitro diagnostics. Abbott agreed to pay the Company an initial license fee of $10.0 million in connection with the execution of the Abbott License Agreement, which was recognized as license revenue during 2020. Abbott also agreed to pay the Company 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.

The Abbott License Agreement will continue until expiration of the last-to-expire licensed patent, or the agreement is earlier terminated. Under the terms of the Abbott License Agreement, the Company and Abbott each have the right to terminate the agreement for uncured material breach by, or insolvency of, the other party. Abbott may also terminate the Abbott License Agreement at any time, without cause, upon 60 days’ notice.

During the three and six months ended June 30, 2023, the Company recognized $0.5 million of one-time revenue related to the expiration of a previously paid for option to expand the scope of the Abbott License Agreement.

Grant Revenue

The Company recognizes grant revenue after funding is committed and as each grant’s related activities are performed. The timing of revenue recognition and receipt of funding varies by grant and can be independent from performance of the related activities, such as an upfront payment of the award value, or subsequent to the Company’s requests for reimbursement for already performed activities (subject to the approval of the granting organization), as further described below.

NIH Grant

On September 21, 2022, the Company and the National Institutes of Health (the “NIH”) entered into a contract (the “NIH Grant”) with a total award value of $1.7 million. The NIH is an agency of the U.S. Department of Health and Human Services and granted the Company funding in support of the development of certain point-of-care diagnostic technologies through collaborative efforts. Grant funding is to be used solely for activities related to the point-of-care diagnostic device development project and the contract period runs through August 2025. Receipt of the award value occurs throughout the term of the contract period and after the Company submits for reimbursement of activities related to the grant. As of June 30, 2023, the Company had not received any of the award value.

During the three and six months ended June 30, 2023, grant revenue recognized and research and development expenses incurred were immaterial.

ADDF Grant

On March 24, 2022, the Company and the Alzheimer’s Drug Discovery Foundation (the “ADDF”) entered into a contract (the “ADDF Grant”) with a total funding value of $2.3 million. The ADDF is a charitable venture philanthropy entity that granted the Company funding in support of certain activities for the development of an in vitro diagnostic test for early detection of Alzheimer's disease. The ADDF Grant restricts the Company’s use of the granted funds solely for activities related to the Company’s Alzheimer’s diagnostic test development project and the contract period runs through June 2024. Receipt of the contract funding was subject to achievement of pre-defined milestones, and as of June 30, 2023, the Company had received the total funding value of $2.3 million.

During the three and six months ended June 30, 2023 and 2022, grant revenue recognized and research and development expenses incurred were immaterial.

RADx Grant

On September 29, 2020, the Company entered into a contract with the NIH under its Rapid Acceleration of Diagnostics (“RADx”) program (the “RADx Grant”), with a total award value of $18.2 million. The RADx Grant was to accelerate the continued development, scale-up, and deployment of the novel SARS-CoV-2 antigen detection test using the Company’s Simoa technology. Grant funding was used to expand assay kit manufacturing capacity and commercial deployment readiness, and the contract ran through the final milestone on May 31, 2022. Receipt of the award value occurred throughout the term of the contract period and after the Company submitted for reimbursement of activities related to the grant. During the three months ended June 30, 2022, the Company received $0.5 million which represented the final and total funding value of the $18.2 million award.

During both the three and six months ended June 30, 2022, the Company recognized no grant revenue and incurred no research and development expenses. As of June 30, 2022, the Company had no future obligations under the RADx Grant.

Contract Assets and Liabilities

There were no contract assets of as June 30, 2023 or December 31, 2022.

During the six months ended June 30, 2023 and 2022, the Company recognized $4.9 million and $3.6 million of revenue, respectively related to its deferred revenue balance at January 1 of each such period.

Remaining Performance Obligations

As of June 30, 2023, the aggregate amount of transaction price allocated to performance obligations that have not yet been satisfied, or are partially satisfied, was $11.7 million.

Of the performance obligations not yet satisfied or partially satisfied, $10.4 million is expected to be recognized as revenue in the next 12 months, with the remainder expected to be recognized within the 24 months thereafter. The $10.4 million principally consists of amounts billed for undelivered services related to initial and extended service-type warranties and research services.

Costs to Obtain a Contract

The Company capitalizes commissions paid to its sales representatives and related fringe benefits costs that are incremental to obtaining customer contracts. These costs are included in prepaid expenses and other current assets on the Consolidated Balance Sheets. Changes in costs to obtain a contract were as follows (in thousands):

	2023		2022
Balance at December 31 of prior year	$	377	$	440

Balance at June 30	$	379	$	410

Costs to obtain a contract are amortized to earnings over the estimated life of the contract and are recorded in cost of goods sold and selling, general, and administrative expense on the Consolidated Statements of Operations. The Company evaluates potential impairment of these amounts at each balance sheet date, and no related impairments were recorded during the six months ended June 30, 2023 or 2022.

Note 4. Allowance for Credit Losses

The Company is exposed to credit losses primarily through accounts receivable from sales of its products and services. The Company’s expected credit loss allowance methodology is developed using historical collection experience, current and future economic and market conditions, and a review of the status of customers’ accounts receivable.

Customers are assessed for credit worthiness upfront through a credit review, which includes analysis of customers’ financial statements when a credit rating is not available.

The allowance for credit losses on accounts receivable is summarized as follows (in thousands):

	2023		2022
Balance at December 31 of prior year	$	118	$	419
Provision for expected credit losses		516		581
Write-offs and recoveries collected		(192)		—

Note 5. Fair Value of Financial Instruments

Recurring Fair Value Measurements

The following tables present the Company’s fair value hierarchy for its financial assets that are measured at fair value on a recurring basis (in thousands):

As of June 30, 2023	Total		Quoted prices in active markets (Level 1)		Significant other observable inputs (Level 2)		Significant unobservable inputs (Level 3)
Financial assets:

Total Financial Assets	$	306,097	$	306,097	$	—	$	—

Nonrecurring Fair Value Measurements

On June 26, 2023, the Company received ordinary shares in UltraDx (refer to Note 3 – Revenue and Related Matters) which were valued at $1.0 million upon receipt, primarily using the third-party purchase price of similar interests issued during UltraDx’s financing event that closed in the second quarter of 2023. As UltraDx is a recently formed, privately held entity, there is minimal market activity or other financial information available to determine the fair value of UltraDx’s shares and therefore this investment is considered a Level 3 financial asset. Changes in the inputs and assumptions used would have resulted in a higher or lower fair value measurement.

Pursuant to ASC 321 – Investments – Equity Securities, the Company has elected the measurement alternative for equity investments without readily determinable fair values and will continue to recognize the UltraDx shares at cost, less any impairment, and adjusted for any observable price changes in orderly transactions.

15

As of June 30, 2023 and December 31, 2022, the carrying value of the Company’s Level 3 financial assets was $1.3 million and $0.3 million, respectively.

These assets are included in other non-current assets on the Consolidated Balance Sheets. Refer to Note 15 – Variable Interest Entities for further discussion.

Other Fair Value Disclosures

During the six months ended June 30, 2023 and 2022, the Company did not transfer financial assets between levels of the fair value hierarchy. Additionally, there have been no changes to the valuation techniques for Level 3 financial assets.

Employee Stock Purchase Plan (“ESPP”)

In December 2017, the Company adopted the 2017 Employee Stock Purchase Plan (the “2017 ESPP”). The 2017 ESPP contains an “evergreen” provision, which allows for an increase in the number of shares under the plan on the first day of each fiscal year beginning with fiscal year 2018. The increase is equal to the lowest of: (i) 1% of the number of shares of common stock outstanding on the last day of the immediately preceding fiscal year and (ii) an amount determined by the Company’s Board of Directors or Compensation Committee. On January 3, 2023, the number of shares of common stock available for issuance under the 2017 ESPP was increased by 372 thousand shares.

The 2017 ESPP provides for six-month offering periods commencing and ending as follows: March 1 through August 31, and September 1 through February 28. During the six months ended June 30, 2023, employees purchased 70 thousand shares of the Company’s common stock pursuant to the 2017 ESPP.

The fair value of the Company’s stock options granted and purchase rights to the ESPP were estimated using the Black-Scholes valuation model with the following assumptions:

	Three Months Ended June 30,				Six Months Ended June 30,
		2023		2022		2023		2022
Stock Options:

Note 9. Net Loss Per Share

The following table presents the computation of basic and diluted net loss per share (in thousands, except per share data):

		Three Months Ended June 30,				Six Months Ended June 30,
		2023		2022		2023		2022
Numerator:
Net loss	$	(6,064)	$	(24,902)	$	(12,167)	$	(43,055)
Denominator:
Weighted average common shares outstanding		37,494		36,922		37,411		36,887
Net loss per share, basic and diluted	$	(0.16)	$	(0.67)	$	(0.33)	$	(1.17)

In periods when the Company is in a net loss position, dilutive securities are excluded from the computation of diluted earnings per share because their inclusion would have an anti-dilutive effect. Therefore, basic net loss per share is the same as diluted net loss per share.

The following common share equivalents have been excluded from the calculation of diluted net loss per share (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2023	2022	2023	2022
Common stock and RSUs	1,607	928	1,557	759

Total anti-dilutive shares	4,498	3,506	4,367	3,142

Note 10. Income Taxes

The Company’s effective tax rates were 4.0% and 3.2% for the three and six months ended June 30, 2023, respectively, and 0.0% for each of the three and six months ended June 30, 2022. The income tax provision and effective tax rate is driven primarily by a valuation allowance in the United States, partially offset by income taxes in foreign jurisdictions.

18

The Company maintains a valuation allowance on the majority of its deferred tax assets, and it has concluded that it is more likely than not that the deferred assets will not be utilized.

Note 11. Goodwill

During the third quarter of 2022, the Company identified certain indicators of impairment, including a significant decline in the Company’s stock price, actions taken under the Restructuring Plan (refer to Note 14 - Restructuring), and a reduction of forecasted sales and profitability. As a result, the Company performed a goodwill impairment test and determined its goodwill was impaired as the carrying amount of the Company’s sole reporting unit exceeded its estimated fair value. The Company concluded that its entire goodwill balance was impaired and recognized an $8.2 million non-cash impairment charge during the third quarter of 2022.

As of June 30, 2023 and December 31, 2022, the Company had no remaining goodwill balance.

The Company accrues for contingent liabilities when losses are probable and estimable. If an estimate of a probable loss is a range and no amount within the range is more likely than any other amount in the range, the Company accrues the minimum amount of the range.

Leases

Operating lease obligations are recorded in operating lease liabilities and operating lease liabilities, net of current portion on the Consolidated Balance Sheets.

Future minimum lease payments under non-cancellable operating leases were as follows (in thousands):

As discussed in Note 3 – Revenue and Related Matters, on May 26, 2022, the Company and UltraDx, a company formed by ARCH, entered into the UltraDx Agreement to supply certain instruments and to grant certain licenses. At contract inception, the Company determined that UltraDx was a related party because a member of the Company’s Board of Directors was affiliated with ARCH and UltraDx. As of June 7, 2023, this individual was no longer a member of the Company’s Board of Directors. Cost of goods sold for both the three and six months ended June 30, 2023 were immaterial. At June 30, 2023 and December 31, 2022, there were no open payable balances to UltraDx and open receivable balances from UltraDx were $0.4 million and zero, respectively.

Note 14. Restructuring

Following a strategic review and assessment of the Company’s operations and cost structure, on August 8, 2022, the Company announced a restructuring and strategic re-alignment plan (the “Restructuring Plan”). As part of the Restructuring Plan, the Company began an assay redevelopment program with the ultimate objective of improving its ability to manufacture and deliver high-quality assays at scale. The Restructuring Plan aligns the Company’s investments to best serve the needs of its customers, focuses the Company’s innovation efforts on key platforms, and provides a foundation for the Company’s entry into translational pharma and clinical markets, which it believes will be required to access new growth categories. In accordance with the Restructuring Plan, the Company implemented a workforce reduction, which was substantially completed by the end of the third quarter of 2022. The Restructuring Plan included the elimination of 119 positions and other cost-saving measures.

As a result of the Restructuring Plan, the Company performed an impairment assessment of its goodwill, long-lived assets, including operating lease right-of-use assets, and intangibles. The assessments resulted in the Company recording an impairment charge of $25.6 million during the year ended December 31, 2022. The impairment charge included (1) $16.3 million associated with the operating lease right-of-use asset and related property and equipment at leased facilities, (2) $8.2 million of goodwill (refer to Note 11 – Goodwill), and (3) $1.1 million for software costs related to projects that were rationalized as part of the Restructuring Plan. There were no impairment charges recorded associated with the Restructuring Plan during the three and six months ended June 30, 2023. There were no material changes to the Restructuring Plan or the exit and disposal costs in 2023.

The following table presents the restructuring reserve and provision activity for the six months ended June 30, 2023 (in thousands):

	Severance and Employee Benefit Costs
Balance at December 31, 2022	$	328
Accrual adjustments		(33)
Cash payments		(16)
Foreign currency translation		5
Balance at June 30, 2023	$	284

The Company did not have any restructuring activities during the six months ended June 30, 2022.

Note 15. Variable Interest Entities

The Company enters into relationships with or has investments in other entities that may be VIEs. The Company assesses the criteria in ASC 810 – Consolidation to determine if any of these entities meet the definition of a VIE and require consolidation into its financial statements. The Company’s analysis determines whether it has a controlling financial interest and also identifies the primary beneficiary of a VIE as the enterprise that has both (1) the power to direct activities of a VIE that most significantly impact the entity’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity.

As discussed in Note 3 – Revenue and Related Matters, during the second quarter of 2023 the Company received one million ordinary shares of UltraDx under the UltraDx Agreement. Primarily due to having less than a 5% ownership interest in UltraDx, the Company concluded that it does not have the power to direct activities impacting UltraDx’s economic performance and therefore the Company is not the primary beneficiary of the VIE.

Based on the Company’s assessments, it does not have any controlling financial interests in any VIEs, and therefore did not consolidate any VIEs into its Consolidated Financial Statements during the three and six months ended June 30, 2023 and 2022.

As of June 30, 2023 and December 31, 2022, the carrying value of the Company’s investment interests in VIEs was $1.3 million and $0.3 million, respectively, which are recorded in other non-current assets on the Consolidated Balance Sheets. Refer to Note 5 – Fair Value of Financial Instruments for the Company’s related valuation disclosures. Maximum exposure to losses related to these VIEs is limited to their carrying value and the Company does not have any future funding commitments to these VIEs.

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. 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.

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. As the installed base of the Simoa instruments increases, we expect total consumables revenue to increase.

We commercially launched our first immunoassay platform, the Simoa HD-1, in 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 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 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. By June 30, 2023, approximately 81% of the HD instrument installed base was HD-X instruments.

With our acquisition of Aushon BioSystems, Inc. in 2018, we acquired a CLIA-certified laboratory, as well as their proprietary sensitive planar array detection technology. Leveraging our proprietary sophisticated Simoa image analysis and data analysis algorithms, we further refined the planar array technology to develop the SP-X instrument to provide sensitivity similar to that found in our Simoa bead-based platform. We commercially launched the SP-X instrument in 2019.

Our wholly-owned subsidiary UmanDiagnostics AB (“Uman”), a company located in Umeå, Sweden, supplies neurofilament light (“Nf-L”), antibodies, and enzyme-linked immunoassay (“ELISA”) kits, which are used by

23

researchers and biopharmaceutical and diagnostics companies world-wide in the detection of Nf-L to advance the development of therapeutics and diagnostics for neurodegenerative conditions.

We also provide contract research services for customers through our CLIA-certified Accelerator Laboratory. The Accelerator Laboratory provides customers with access to Simoa technology, and supports multiple projects and services, including sample testing, homebrew assay development, and custom assay development. To date, we have completed over 2,000 projects for more than 450 customers from all over the world using our Simoa platforms.

We sell our instruments, consumables and services to the life science, pharmaceutical, and diagnostics industries 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, India, Hong Kong, Israel, Japan, New Zealand, Qatar, Saudi Arabia, Singapore, South Africa, South Korea, Taiwan, and the United Arab Emirates. In addition, Uman sells Nf-L antibodies and Nf-L ELISA kits directly, and in conjunction with us and another distributor, worldwide. We have an extensive base of customers in academic and governmental research institutions, as well as pharmaceutical, biotechnology, and contract research companies.

As of June 30, 2023, we had cash and cash equivalents of $329.5 million. Since our inception, we have incurred annual net losses. Our net losses were $6.1 million and $12.2 million for the three and six months ended June 30, 2023 and $24.9 million and $43.1 million for the three and six months ended June 30, 2022, respectively. As of June 30, 2023, we had an accumulated deficit of $414.3 million and stockholders' equity of $355.4 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 as we:

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

● 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 U.S. Food and Drug Administration (the “FDA”) to be medical devices or otherwise subject to additional regulation by the FDA;

● seek Premarket Approval (“PMA”) or 510(k) clearance 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 grow our employee headcount;

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

● intend to invest in our diagnostics business in support of the launch of LucentAD and other diagnostics initiatives;

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

● add operational, financial, and management information systems.

Recent Business Developments

In July 2023, we launched LucentAD, a blood-based biomarker test to assist in the evaluation of patients experiencing cognitive symptoms consistent with the early signs of Alzheimer’s disease. The test has not been cleared or approved by the FDA.

On September 21, 2022, we entered into a contract with the National Institutes of Health (the “NIH”) with a total award value of $1.7 million (the “NIH Grant”). The NIH is an agency of the U.S. Department of Health and Human Services and under the NIH Grant granted us funding in support of the development of certain point-of-care diagnostic technologies through collaborative efforts. Grant funding is to be used solely for activities related to the point-of-care diagnostic device development project and the contract period runs through August 2025. Receipt of the award value occurs throughout the term of the contract period and after we submit for reimbursement of activities related to the grant. As of June 30, 2023, we had not received any of the award value.

24

During the three and six months ended June 30, 2023, grant revenue recognized and research and development expense incurred were immaterial.

On March 24, 2022, we entered into a contract with the Alzheimer’s Drug Discovery Foundation (the “ADDF”) with a total funding value of $2.3 million (the “ADDF Grant”). The ADDF is a charitable venture philanthropy entity that granted us funding in support of certain activities for the development of an in vitro diagnostic test for early detection of Alzheimer's disease. The ADDF Grant restricts our use of the granted funds solely for activities related to our Alzheimer’s diagnostic test development project and the contract period runs through June 2024. Receipt of the contract funding was subject to achievement of predefined milestones and as of June 30, 2023, we had received the total funding value of $2.3 million.

During the three and six months ended June 30, 2023 and 2022, grant revenue recognized and research and development expense incurred were immaterial.

On February 25, 2022, we entered into a Master Collaboration Agreement with Eli Lilly and Company (“Lilly”) establishing a framework for future projects focused on the development of Simoa immunoassays (the “Lilly Collaboration Agreement”). We also entered into a statement of work under the Lilly Collaboration Agreement to perform assay research and development services within the field of Alzheimer’s disease. In connection with the Lilly Collaboration Agreement, we received a non-refundable up-front payment of $5.0 million during the first quarter of 2022, which was recognized over a one-year period. In addition, under the statement of work, we receive $1.5 million per calendar, which began in the first quarter of 2022. The statement of work automatically renews on a quarterly basis until Lilly provides a termination notice in accordance with the terms of the Lilly Collaboration Agreement. As of June 30, 2023, the Lilly Collaboration Agreement and the statement of work were still in effect.

Concurrent with the execution of the Lilly Collaboration Agreement, we entered into a Technology License Agreement (the “Lilly License”) under which Lilly granted us a non-exclusive license to Lilly’s proprietary pTau217 antibody technology for use in research use only products and services and future in vitro diagnostics applications within the field of Alzheimer’s disease. In consideration of the Lilly License, we paid an upfront fee, are required to make milestone payments based on the achievement of predetermined regulatory and commercial events, and will pay royalties on net sales of licensed products.

We recognized revenue from the Lilly Collaboration Agreement of $1.5 million and $3.0 million during the three and six months ended June 30, 2023, respectively, and $2.7 million and $5.4 million during the three and six months ended June 30, 2022, respectively.

Restructuring and Strategic Re-Alignment

Following a strategic review and assessment of our operations and cost structure, on August 8, 2022, we announced a restructuring and strategic re-alignment plan (the “Restructuring Plan”). As part of the Restructuring Plan, we began an assay redevelopment program with the ultimate objective of improving our ability to manufacture and deliver high-quality assays at scale. The Restructuring Plan aligns our investments to best serve the needs of our customers, focuses our innovation efforts on key platforms, and provides a foundation for our entry into translational pharma and clinical markets, which we believe will be required to access new growth categories. In accordance with the Restructuring Plan, we implemented a workforce reduction, which was substantially completed by the end of the third quarter of 2022. The Restructuring Plan included the elimination of 119 positions and other cost-saving measures.

As a result of the Restructuring Plan, we performed an impairment assessment of our goodwill, long-lived assets, including operating lease right-of-use assets, and intangibles. The assessments resulted in us recording an impairment charge of $25.6 million during the year ended December 31, 2022. The impairment charge included (1) $16.3 million associated with the right-of-use asset and property and equipment at leased facilities, (2) $8.2 million of goodwill (refer to Note 11 – Goodwill in the Notes to Consolidated Financial Statements), and (3) $1.1 million for software costs related to projects that were rationalized as part of the Restructuring Plan. There were no impairment charges recorded associated with the Restructuring Plan during the three and six months ended June 30, 2023. There were no material changes to the Restructuring Plan or the exit and disposal costs in 2023.

25

Overall, as a result of the Restructuring Plan, we expect to realize estimated annualized operating expense savings of approximately $25 million.

Revenues

Total revenues increased $7.5 million, or 32%, to $31.0 million for the three months ended June 30, 2023, compared to $23.5 million for the three months ended June 30, 2022.

Product revenue of $19.7 million for the three months ended June 30, 2023 consisted of instrument sales of $3.5 million and sales of consumables and other products of $16.2 million. This represented an increase of $4.9 million, or 33%, as compared to product revenue of $14.8 million for the three months ending June 30, 2022, which consisted of $5.6 million in instrument sales and $9.2 million in sales of consumables and other products. The increase in product revenue resulted primarily from (1) increased sales of consumables, (2) increased average selling prices, and (3) a one-time increase from the receipt of ordinary shares from UltraDx with a fair value of $1.0 million that was accounted as variable consideration under the UltraDx Agreement (as a Level 3 financial asset with minimal market activity or other data available, the fair value was determined primarily using the third-party purchase price of similar instruments issued by UltraDx). These increases were partially offset by lower instrument sales due to reduced demand in certain markets. We expect this instrument trend to continue for the remainder of 2023.

Service revenue was $10.6 million for the three months ended June 30, 2023, compared to $8.5 million for the three months ended June 30, 2022, an increase of $2.1 million, or 23%, primarily due to increased Accelerator Laboratory revenue, partially offset by lower revenue recognized from the Lilly Collaboration Agreement.

26

Collaboration and license revenue was $0.6 million for the three months ended June 30, 2023, compared to $0.1 million for the three months ended June 30, 2022, an increase of $0.5 million, or 584%. This was due to a one-time increase from the expiration of a previously paid for option to expand the scope of the Abbott License Agreement.

Grant revenue was $0.2 million for the three months ended June 30, 2023, compared to $0.1 million for the three months ended June 30, 2022.

Cost of Goods Sold and Services

Cost of goods sold and services decreased $2.9 million, or 20%, to $11.9 million for the three months ended June 30, 2023 compared to $14.8 million for the three months ended June 30, 2022, primarily due to decreased cost of product revenue.

Cost of product revenue decreased $2.7 million, or 27%, to $7.2 million for the three months ended June 30, 2023, compared to $9.9 million for the three months ended June 30, 2022, as a result of improved inventory management and lower instrument sales. Cost of service revenue decreased $0.2 million, or 4%, to $4.7 million for the three months ended June 30, 2023, compared to $4.9 million for the three months ended June 30, 2022 as a result of decreased lab services expenses.

Research and Development

Research and development expense decreased $0.7 million, or 10%, to $5.9 million for the three months ended June 30, 2023, as compared to $6.6 million for the three months ended June 30, 2022, primarily due to the reduction in headcount in connection with the Restructuring Plan.

Selling, General, and Administrative

Selling, general and administrative expense decreased $5.4 million, or 20%, to $21.6 million for the three months ended June 30, 2023, as compared to $27.0 million for the three months ended June 30, 2022, primarily due to the reduction in headcount in connection with the Restructuring Plan. Included within selling, general, and administrative expense are $1.6 million and $1.9 million of shipping and handling costs for product sales for the three months ended June 30, 2023 and 2022, respectively.

Other Lease Costs

During the three months ended June 30, 2023, we incurred other lease costs of $1.2 million. As part of the Restructuring Plan, we are not utilizing the leased office and laboratory facilities in Bedford, Massachusetts and are evaluating alternatives, including sub-leasing the facilities. Other lease costs include amortization of the related operating lease right-of-use assets and other leased facility operating expenses from periods after the impairment and the determination that the facilities would not be utilized. There were no similar charges for the three months ended June 30, 2022.

Interest Income, Net

Interest income, net was $3.9 million for the three months ended June 30, 2023, as compared to $0.6 million for the three months ended June 30, 2022, primarily due to higher interest rates earned on cash and cash equivalents.

Other Expense, Net

Other expense, net was ($0.2) million in the three months ended June 30, 2023, as compared to ($0.4) million in the three months ended June 30, 2022.

27

Income Tax Expense, Net

Income tax expense, net was ($0.2) million for the three months ended June 30, 2023, as compared to ($0.1) million for the three months ended June 30, 2022, consisting primarily of a provision recorded on the operating results of our foreign subsidiaries.

Revenues

Total revenues increased $6.4 million, or 12%, to $59.5 million for the six months ended June 30, 2023, compared to $53.1 million for the six months ended June 30, 2022.

Product revenue of $39.0 million for the six months ended June 30, 2023 consisted of instrument sales of $8.8 million and sales of consumables and other products of $30.2 million. This represented an increase of $3.5 million, or 10%, as compared to product revenue of $35.4 million for the six months ending June 30, 2022, which consisted of $11.8 million in instrument sales and $23.6 million in sales of consumables and other products. The increase in product revenue resulted primarily from (1) increased sales of consumables, (2) increased average selling prices, and (3) a one-time increase from the receipt of ordinary shares of UltraDx with a fair value of $1.0 million that was accounted for as variable consideration under the UltraDx Agreement (as a Level 3 financial asset with minimal market activity or other data available, the fair value was determined primarily using the third-party purchase price of similar instruments issued by UltraDx). These increases were partially offset by lower instrument sales due to reduced demand in certain markets. We expect this instrument trend to continue for the remainder of 2023.

28

Service revenue was $19.1 million for the six months ended June 30, 2023, compared to $17.4 million for the six months ended June 30, 2022, an increase of $1.7 million, or 10%, primarily due to increased Accelerator Laboratory revenue, partially offset by lower revenue recognized from the Lilly Collaboration Agreement.

Collaboration and license revenue was $1.0 million for the six months ended June 30, 2023, compared to $0.2 million for the six months ended June 30, 2022, an increase of $0.8 million, or 460%. This was primarily due to a one-time increase from the expiration of a previously paid for option to expand the scope of the Abbott License Agreement.

Grant revenue was $0.4 million for the six months ended June 30, 2023, compared to $0.1 million for the six months ended June 30, 2022.

Cost of Goods Sold and Services

Cost of goods sold and services decreased $6.4 million, or 21%, to $23.4 million for the six months ended June 30, 2023 compared to $29.8 million for the six months ended June 30, 2022, primarily due to improved inventory management and lower instrument sales.

Cost of product revenue decreased $6.4 million, or 31%, to $14.3 million for the six months ended June 30, 2023, compared to $20.7 million for the six months ended June 30, 2022, as a result of improved inventory management and lower instrument sales. The increase in cost of service revenue was immaterial for the six months ended June 30, 2023 compared to the six months ended June 30, 2022.

Research and Development

Research and development expense decreased $3.0 million, or 22%, to $10.7 million for the six months ended June 30, 2023, as compared to $13.7 million for the six months ended June 30, 2022, primarily due to the reduction in headcount in connection with the Restructuring Plan.

Selling, General, and Administrative

Selling, general and administrative expense decreased $10.3 million, or 19%, to $42.5 million for the six months ended June 30, 2023, as compared to $52.8 million for the six months ended June 30, 2022, primarily due to the reduction in headcount in connection with the Restructuring Plan. Included within selling, general and administrative expense are $3.5 million and $3.6 million of shipping and handling costs for product sales for the six months ended June 30, 2023 and 2022, respectively.

Other Lease Costs

During the six months ended June 30, 2023, we incurred other lease costs of $1.9 million. As part of the Restructuring Plan, we are not utilizing the leased office and laboratory facilities in Bedford, Massachusetts and are evaluating alternatives, including sub-leasing the facilities. Other lease costs include the amortization of the related operating lease right-of-use assets and other leased facility operating expenses from periods after the impairment and the determination that the facilities would not be utilized. There were no similar charges for the six months ended June 30, 2022.

Interest Income, Net

Interest income, net was $7.3 million for the six months ended June 30, 2023, as compared to $0.6 million for the six months ended June 30, 2022, due to higher interest rates earned on cash and cash equivalents.

Other Expense, Net

Other expense, net was ($0.1) million for the six months ended June 30, 2023, as compared to ($0.6) million for the six months ended June 30, 2022, primarily due to changes in foreign exchange rates.

29

Income Tax (Expense) Benefit, Net

Income tax (expense) benefit, net was ($0.4) million for the six months ended June 30, 2023, as compared to $0.1 million for the six months ended June 30, 2022, primarily due to recording a provision for the operating results of our foreign subsidiaries.

Liquidity and Capital Resources

Our principal sources of liquidity are cash, cash equivalents, and funds generated from sales of our products and services. As of June 30, 2023, we had cash and cash equivalents of $329.5 million. Historically we have also financed our operations through equity offerings and borrowings from credit facilities.

Cash Flows

The following table summarizes our cash flows (in thousands):

	Six Months Ended June 30,				Increase (Decrease)
	2023		2022		Amount		%
Net cash used in operating activities	$	(8,869)	$	(29,635)	$	20,766	70	%
Net cash used in investing activities		(784)		(5,934)		5,150	87	%
Net cash provided by financing activities		690		1,190		(500)	42	%
Net decrease in cash, cash equivalents, and restricted cash	$	(8,963)	$	(34,379)	$	25,416	74	%

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 develop new products and services, invest in process and product improvements, and increase our sales and marketing efforts. We have historically experienced negative cash flows from operating activities as we have developed our technology, expanded our business, and built our infrastructure. We expect negative cash flows from operating activities may continue in the future.

Net cash used in operating activities was $8.9 million during the six months ended June 30, 2023 which primarily consisted of the net loss of $12.2 million, offset by non-cash charges of $8.1 million of stock-based compensation expense, $2.8 million of depreciation and amortization expense, and non-cash lease expense of $1.0 million. Cash used as a result of changes in operating assets and liabilities of $9.5 million was primarily due to an increase in accounts receivable of $5.8 million, a decrease in operating lease liabilities of $1.6 million, a decrease in accrued compensation and benefits, other accrued expenses and other current liabilities of $1.3 million and an increase in inventory of $1.2 million. These decreases were primarily offset by an increase in deferred revenue of $1.7 million and $0.9 million received on the tenant improvement allowance associated with our leased facilities in Bedford, Massachusetts.

Net cash used in operating activities was $29.6 million during the six months ended June 30, 2022. The net cash used in operating activities primarily consisted of the net loss of $43.1 million, offset by non-cash charges of $9.0 million of stock-based compensation expense, $2.8 million of depreciation and amortization expense, and $1.4 million received on the tenant improvement allowance associated with our leased facility in Bedford, Massachusetts.

Net Cash Used in Investing Activities

Our primary investing activities consist of capital expenditures for the purchase of equipment to support our expanding infrastructure and work force. We expect to continue to incur additional capital expenditures related to these efforts in future periods. Cash used towards capital expenditures can be partially offset by proceeds from grants with

30

third parties to purchase assets (refer to the section titled “Grant Revenue” in Note 3 – Revenue and Related Matters in the Notes to Consolidated Financial Statements for more information).

We used $0.8 million and $5.9 million in cash in investing activities during the six months ended June 30, 2023 and June 30, 2022, respectively, for purchases of property and equipment. The purchases during the six months ended June 30, 2022 were partially offset by $0.5 million in grant proceeds under the RADx Grant.

Net Cash Provided by Financing Activities

Our primary financing activities are proceeds from sales of our common stock.

Financing activities provided $0.7 million and $1.2 million of cash during the six months ended June 30, 2023 and June 30, 2022, respectively, from the proceeds of common stock issued.

Capital Resources

We have not achieved profitability on an annual basis since our inception, and we expect to continue to incur net losses in the future. We also expect that our operating expenses will increase as we continue to increase our marketing efforts to drive adoption of our commercial products, as well as our investment in improving the quality of our products and services. Our liquidity requirements have consisted, and we expect that they will continue to consist, of sales and marketing expenses, research and development expenses, working capital, and general corporate expenses.

We believe cash generated from product and services sales along with our current cash and cash equivalents will be sufficient to meet our anticipated operating cash requirements for at least 12 months from the date of this Quarterly Report on Form 10-Q. In the future, we expect our operating and capital expenditures to increase as we increase headcount, expand our 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. Actual results could vary materially and negatively as a result of a number of factors, including the factors discussed in the section titled “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K.

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 but not limited to:

● continued market acceptance of our products and services and the ability of our products to meet our customers’ expectations;

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

● the extent to which we achieve intended cost savings, revenue improvement, and related benefits from our Restructuring Plan; 

● the extent to which we are able to successfully complete our assay improvement program to enhance product quality; 

● the cost of our research and development activities;

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

● potential opportunities to strategically acquire and integrate companies or technologies that may be complementary to our business;

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

● the effect of competing technological and market developments.

We cannot guarantee 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

31

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 and services. We also may have to reduce marketing, customer support or other resources devoted to our products, or cease operations.

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.

Contractual Obligations and Commitments

As of June 30, 2023, there have been no material changes to our contractual obligations and commitments from those described in the section titled “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K.

In addition to these cash commitments disclosed in our Annual Report on Form 10-K, we may have other payables and liabilities that may be legally enforceable but are not considered contractual commitments.

Critical Accounting Policies and Estimates

Our critical accounting policies and significant estimates that involve a higher degree of judgment and complexity are described in the section titled “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies, Significant Judgments and Estimates” included in our Annual Report on Form 10-K.

There have been no material changes to our critical accounting policies and estimates as previously disclosed in that report.

Related Party Transactions

Refer to Note 13 – Related Party Transactions in the Notes to Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for a full description of related party transactions.

Non-GAAP Financial Measures

To supplement our financial statements presented on a U.S. GAAP basis, we present non-GAAP gross profit, non-GAAP gross margin, non-GAAP total operating expenses, and non-GAAP loss from operations, which are calculated by including shipping and handling costs for product sales within cost of goods sold instead of within selling, general, and administrative expenses. Management uses these non-GAAP measures to evaluate our operating performance in a manner that allows for meaningful period-to-period comparison and analysis of trends in our business and our competitors. Management believes that presentation of these non-GAAP measures provides useful information to investors in assessing our operating performance within our industry and in order to allow comparability to the presentation of other companies in our industry where shipping and handling costs are included in cost of goods sold for products. Management also uses these non-GAAP measures as a factor in assessing our progress against the Restructuring Plan. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, the financial information presented in accordance with U.S. GAAP.

Set forth below is a reconciliation of non-GAAP gross profit, non-GAAP gross margin, non-GAAP total operating expenses, and non-GAAP loss from operations to their most directly comparable GAAP financial measures.

Recent Accounting Pronouncements

Refer to Note 2 – Significant Accounting Policies in the Notes to Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for a full description of recent accounting pronouncements, including the expected dates of adoption and effects on our Consolidated Financial Statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

At June 30, 2023, there have been no material changes to the market risk information from those described in the section titled “Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk” included in our Annual Report on Form 10-K.

Item 4. Controls and Procedures

As previously disclosed in the section titled “Part II, Item 9A. Controls and Procedures” in our Annual Report on Form 10-K, management concluded that our internal control over financial reporting was not effective at a reasonable assurance level as of December 31, 2022, due to certain deficiencies that constituted material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

Management has been actively engaged in the implementation of remediation efforts to address the material weaknesses, as well as other identified areas of risk. For a complete description of management’s remediation plan, see the section titled “Part II, Item 9A. Controls and Procedures” in our Annual Report on Form 10-K, as may be updated by Part I. Item 4. “Controls and Procedures” of our subsequently filed Quarterly Reports on Form 10-Q. For updates on management’s remediation plan as of June 30, 2023, see the section titled “Management’s Implementation of Remediation Plan” below.

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC and to ensure that such information is accumulated

33

and communicated to management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer and principal accounting officer), to allow timely decisions regarding required disclosures. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide a reasonable assurance of achieving their objectives. Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of June 30, 2023. Because we commenced implementing efforts to remediate the material weaknesses in our internal control over financial reporting in March 2023 and we have not had a sufficient period of time to test the operating effectiveness of our internal control over financial reporting, which we view as an integral part of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at a reasonable assurance level as of June 30, 2023.

Nevertheless, based on a number of factors, including the performance of additional procedures by management designed to ensure the reliability of our financial reporting, we believe that the Consolidated Financial Statements in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial position, results of operations, and cash flows as of the dates, and for the periods, presented, in conformity with U.S. GAAP.

Management’s Implementation of Remediation Plan

Management, with oversight from the Audit Committee of our Board of Directors, previously commenced implementing changes to our internal control over financial reporting in order to remediate the control deficiencies that resulted in the material weaknesses as previously disclosed in our Annual Report on Form 10-K. As of June 30, 2023, we are on track with the remediation plan disclosed therein. Our ongoing efforts for remediation include, but are not limited to, the following:

● we have hired a Corporate Controller and are actively continuing to hire additional personnel with public company experience who have the appropriate level of expertise in the respective areas of accounting, SEC financial reporting, and associated internal controls commensurate with the type, volume, and complexity of our accounting operations and reporting requirements;

● we have engaged accounting advisory consultants to provide additional depth and breadth in our period end closes, technical accounting, financial reporting capabilities, and internal controls compliance and will continue to utilize such consultants until we have filled vacancies with qualified personnel, with a sufficient period of overlap to ensure successful transition of responsibilities;

● we engaged a third-party service provider who has performed an assessment of our internal control design and operation and provided us recommendations to enhance the effectiveness of such controls;

● we have engaged a third-party consultant who assessed our current enterprise resource planning system and identified opportunities to enhance our use of the system through automating certain controls and processes, for which development of system enhancements are actively underway; and

● we have engaged an accounting advisory consultant to conduct additional trainings on a regular basis related to internal control over financial reporting with our team members including, but not limited to, finance and accounting personnel, which trainings commenced in the first quarter of 2023 and will continue throughout fiscal year 2023.

We will continue our efforts through fiscal year 2023 to remediate the material weaknesses described in our Annual Report on Form 10-K and expect to implement all necessary recommendations during fiscal year 2023. We are actively executing the remediation plan and are focused on implementing those recommendations deemed as high priority. We believe that the implementation of the above steps, will allow us to address the deficient controls within our internal control environment, which will facilitate the remediation of the material weaknesses.

34

Given that many of the remediation efforts described above were recently implemented, we will not be able to consider the material weaknesses remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that our controls are operating effectively. We, along with our Audit Committee, will continue to monitor and evaluate the effectiveness of these remedial actions and take further actions as we deem appropriate.

Changes in Internal Control over Financial Reporting

Other than the changes outlined above to remediate the material weaknesses, there have been no changes in our internal control over financial reporting during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

35

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

In the ordinary course of business, we are from time to time involved in lawsuits, claims, investigations, proceedings and threats of litigation consisting of intellectual property, contractual, employment, and other matters. While the outcome of any such actions or proceedings cannot be predicted with certainty, as of June 30, 2023, we were not party to any legal proceedings, the outcome of which would be expected to have a material adverse effect on our financial condition or results of operations.

Item 1A. Risk Factors

Our business is subject to risks and events that, if they occur, could adversely affect our financial condition, results of operations, or the price of our common stock. In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider the risk factors described in the section titled “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 6, 2023 (the “Annual Report on Form 10-K”). Those risk factors are not the only risks we face. Additional risks and uncertainties not currently known to us or that we deem to be immaterial also may adversely affect our business, financial condition, and results of operations.

As of the date of this Quarterly Report on Form 10-Q, there were no material changes to the risk factors described in our Annual Report on Form 10-K.

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

Not applicable.

Item 3. Defaults Upon Senior Securities

Not applicable.

Item 4. Mine Safety Disclosures

Not applicable.

RESTATED BYLAWS

(effective August 4, 2023)

ARTICLE I - STOCKHOLDERS

Section 1.Annual Meeting.

An annual meeting of the stockholders, for the election of directors to succeed those whose terms expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place, on such date, and at such time as the Board of Directors shall fix.  The Board of Directors may, in its sole discretion, determine that the meeting shall not be held at any place, but instead shall be held solely by means of remote communication as provided under the Delaware General Corporation Law.

Section 2.Special Meetings.

Special meetings of the stockholders of the Corporation may be called only by the Board of Directors acting pursuant to a resolution adopted by a majority of the Whole Board. For the purposes of these Restated Bylaws, the term “Whole Board” shall mean the total number of authorized directors whether or not there exist any vacancies in previously authorized directorships. Special meetings of the stockholders may be held at such place within or without the State of Delaware as may be stated in such resolution.  The Board of Directors may, in its sole discretion, determine that the meeting shall not be held at any place, but instead shall be held solely by means of remote communication as provided under the Delaware General Corporation Law. Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting.

Section 3.Notice of Meetings.

Notice of the place, if any, date, and time of all meetings of the stockholders, and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such meeting, shall be given, not less than ten (10) nor more than sixty (60) days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting, except as otherwise provided herein or required by law (meaning, here and hereinafter, as required from time to time by the Delaware General Corporation Law or the Certificate of Incorporation of the Corporation, as amended and restated from time to time).

- 1 -

When a meeting is adjourned to another place, if any, date or time (including an adjournment taken to address a technical failure to convene or continue a meeting using remote communication), notice need not be given of the adjourned meeting if the place, if any, date and time thereof, and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting, are (i) announced at the meeting at which the adjournment is taken, (ii) displayed, during the time scheduled for the meeting, on the same electronic network used to enable stockholders and proxy holders to participate in the meeting by means of remote communication or (iii) set forth in the notice of meeting given in accordance with this Section; provided, however, that if the date of any adjourned meeting is more than thirty (30) days after the date for which the meeting was originally noticed, or if a new record date is fixed for the adjourned meeting, notice of the place, if any, date, and time of the adjourned meeting, and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting, shall be given in conformity herewith.  At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.

At any meeting of the stockholders, the holders of a majority of the voting power of all of the shares of the stock entitled to vote at the meeting, present in person or by proxy, shall constitute a quorum for all purposes, unless or except to the extent that the presence of a larger number may be required by law or by rules of any stock exchange upon which the Corporation’s securities are listed.  Where a separate vote by a class or classes is required, a majority of the voting power of the shares of such class or classes present in person or represented by proxy shall constitute a quorum entitled to take action with respect to that vote on that matter.

If a quorum shall fail to attend any meeting, the chairman of the meeting may adjourn the meeting to another place, if any, date, or time.

Section 5.Organization and Conduct of Business.

ARTICLE V - STOCK

Section 1.  Certificated and Uncertificated Stock.

Shares of the Corporation’s stock may be certificated or uncertificated, as provided under the General Corporation Law of the State of Delaware, and shall be entered in the books of the Corporation and registered as they are issued.  Any certificates representing shares of stock shall be in such form as the Board of Directors shall prescribe, certifying the number and class of shares of the stock owned by the stockholder.  Any certificates issued to a stockholder of the Corporation shall bear the name of the Corporation and shall be signed by any two (2) authorized officers of the Corporation.  Any or all of the signatures on the certificate may be by facsimile.

Section 2.  Transfers of Stock.

Transfers of stock shall be made only upon the transfer books of the Corporation kept at an office of the Corporation or by transfer agents designated to transfer shares of the stock of the Corporation.  Except where a certificate is issued in accordance with Section4 of this Article of these Bylaws or in the case of uncertificated shares, an outstanding certificate for the number of shares involved shall be surrendered for cancellation before a new certificate is issued therefor.

Section 3.  Record Date.

In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders, or to receive payment of any dividend or other distribution or allotment of any rights or to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of any meeting of stockholders, nor more than sixty (60) days prior to the time for such other action as hereinbefore described.  If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination.  If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of and to vote at a meeting of stockholders shall be at the

- 17 -

close of business on the day next preceding the day on which notice is given or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held, and, for determining stockholders entitled to receive payment of any dividend or other distribution or allotment of rights or to exercise any rights of change, conversion or exchange of stock or for any other purpose, the record date shall be at the close of business on the day on which the Board of Directors adopts a resolution relating thereto.

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 3 at the adjourned meeting.

Section 4.  Lost, Stolen or Destroyed Certificates.

In the event of the loss, theft or destruction of any certificate of stock, the Corporation may issue a new certificate of stock or uncertificated shares in place of any certificate previously issued by the Corporation pursuant to such regulations as the Board of Directors may establish concerning proof of such loss, theft or destruction and concerning the giving of a satisfactory bond or bonds of indemnity.

Section 5.  Regulations.

The issue, transfer, conversion and registration of certificates of stock shall be governed by such other regulations as the Board of Directors may establish.

Section 6.  Interpretation.

The Board of Directors shall have the power to interpret all of the terms and provisions of these Bylaws, which interpretation shall be conclusive.

ARTICLE VI - NOTICES

Section 1.  Notices.

If mailed, notice to stockholders shall be deemed given when deposited in the mail, postage prepaid, directed to the stockholder at such stockholder’s address as it appears on the records of the Corporation.  Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders may be given by electronic transmission in the manner provided in Section 232 of the Delaware General Corporation Law.

- 18 -

Section 2.  Waiver of Notice.

A written waiver of any notice, signed by a stockholder or director, or waiver by electronic transmission by such person, whether before or after the time of the event for which notice is to be given, shall be deemed equivalent to the notice required to be given to such person.  Neither the business nor the purpose of any meeting need be specified in such a waiver.  Attendance at any meeting shall constitute waiver of notice except attendance for the express purpose of objecting at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened.

ARTICLE VII -INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 1.  Right to Indemnification.

Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including, without limitation, as a witness) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director or an officer of the Corporation or is or was serving at the request of the Corporation as a director, officer, or trustee of another corporation, or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “Indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer or trustee or in any other capacity while serving as a director, officer or trustee, shall be indemnified and held harmless by the Corporation to the fullest extent permitted by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such Indemnitee in connection therewith; provided, however, that, except as provided in Section 3 of this Article with respect to proceedings to enforce rights to indemnification or an advancement of expenses or as otherwise required by law, the Corporation shall not be required to indemnify or advance expenses to any such Indemnitee in connection with a proceeding (or part thereof) initiated by such Indemnitee unless such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.

Section 2.  Right to Advancement of Expenses.

In addition to the right to indemnification conferred in Section 1 of this Article, an Indemnitee shall also have the right to be paid by the Corporation the expenses (including attorney’s fees) incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the Delaware General Corporation Law requires, an advancement of expenses incurred by an Indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such Indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such Indemnitee,

- 19 -

to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such Indemnitee is not entitled to be indemnified for such expenses under this Section 2 or otherwise.

Section 3.  Right of Indemnitees to Bring Suit.

If a claim under Section 1 or 2 of this Article is not paid in full by the Corporation within sixty (60) days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the Indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim.  To the fullest extent permitted by law, if successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Indemnitee shall also be entitled to be paid the expenses of prosecuting or defending such suit.  In (i) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the Indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that, the Indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law.  Neither the failure of the Corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its directors who are not parties to such action,  a committee of such directors, independent legal counsel, or its stockholders) that the Indemnitee has not met such applicable standard of conduct, shall create a presumption that the Indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, be a defense to such suit.  In any suit brought by the Indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article or otherwise shall be on the Corporation.

Section 4.  Non-Exclusivity of Rights.

The rights to indemnification and to the advancement of expenses conferred in this Article shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, the Corporation’s Certificate of Incorporation as amended from time to time, these Bylaws, any agreement, any vote of stockholders or disinterested directors or otherwise.

Section 5.  Insurance.

The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust

- 20 -

or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

Section 6. Indemnity Agreements.

The Corporation may enter into indemnity agreements with the persons who are members of its Board of Directors from time to time, and with such officers, employees and agents of the Corporation and with such officers, directors, employees and agents of subsidiaries as the Board of Directors may designate, such indemnity agreements to provide in substance that the Corporation will indemnify such persons as contemplated by this Article, and to include any other substantive or procedural provisions regarding indemnification as are not inconsistent with Delaware law. The provisions of such indemnity agreements shall prevail to the extent that they limit or condition or differ from the provisions of this Article.

Section 7.  Indemnification of Employees and Agents of the Corporation.

The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation to the fullest extent of the provisions of this Article with respect to the indemnification and advancement of expenses of directors and officers of the Corporation.

Section 8.  Nature of Rights.

The rights conferred upon Indemnitees in this Article shall be contract rights and such rights shall continue as to an Indemnitee who has ceased to be a director, officer, employee, agent or trustee and shall inure to the benefit of the Indemnitee’s heirs, executors and administrators.  Any amendment, alteration or repeal of this Article that adversely affects any right of an Indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to any such amendment, alteration or repeal.

Section 9.  Severability.

If any word, clause, provision or provisions of this Article shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Article (including, without limitation, each portion of any section of this Article containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Article (including, without limitation, each such portion of any section of this Article containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

- 21 -

ARTICLE VIII - CERTAIN TRANSACTIONS

Section 1.  Transactions with Interested Parties.

No contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other corporation, partnership, association, or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for this reason, or solely because the director or officer is present at or participates in the meeting of the Board or committee thereof which authorizes the contract or transaction or solely because the votes of such director or officer are counted for such purpose, if:

(a)The material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or

(b)The material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or

Section 2.  Quorum.

Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

- 22 -

or a committee thereof, duplicates of the seal may be kept and used by the Treasurer or by an Assistant Secretary or Assistant Treasurer.

Section 3.  Reliance upon Books, Reports and Records.

Each director, each member of any committee designated by the Board of Directors, and each officer of the Corporation shall, in the performance of his or her duties, be fully protected in relying in good faith upon the books of account or other records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of its officers or employees, or committees of the Board of Directors so designated, or by any other person as to matters which such director or committee member reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation.

Section 6.Pronouns.

Whenever the context may require, any pronouns used in these Bylaws shall include the corresponding masculine, feminine or neuter forms.

ARTICLE X - AMENDMENTS

The Board of Directors is expressly empowered to adopt, amend or repeal these Bylaws.  Any adoption, amendment or repeal of these Bylaws by the Board of Directors shall require the approval of a majority of the Whole Board.  The stockholders shall also have power to adopt, amend or repeal these Bylaws; provided, that in addition to any vote of the holders of any class or series of stock of the Corporation required by law, the Restated Certificate of Incorporation, these Bylaws or any Preferred Stock, the affirmative vote of the holders of at least seventy-five percent (75%) of the voting power of all of the then outstanding shares of the capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required for the stockholders to adopt, amend or repeal any provision of these Bylaws; provided, however, that if the Board of Directors recommends that stockholders approve such

- 23 -

adoption, amendment or repeal, such adoption, amendment or repeal shall only require, in addition to any vote of the holders of any class or series of the capital stock of the Corporation required by law, the Restated Certificate of Incorporation, these Bylaws or any Preferred Stock, the affirmative vote of the holders of the majority of the voting power of all of the then outstanding shares of capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1. Organization and Nature of Business

Quanterix Corporation (“Quanterix” or 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. The Company is currently focusing on protein detection, but its Simoa platforms have also demonstrated applicability across other testing applications, including detection of nucleic acids and small molecules.

The Company also provides contract research services for customers through its CLIA-certified Accelerator Laboratory. The Accelerator Laboratory provides customers with access to Simoa technology and supports multiple projects and services, including sample testing, homebrew assay development, and custom assay development. To date, the Company has completed over 2,000 projects for more than 450 customers from all over the world using its Simoa platforms.

Note 2. Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with the generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting on Form 10-Q. Accordingly, certain information and disclosures required for complete financial statements prepared in accordance with U.S. GAAP are not included herein. The Consolidated Balance Sheet included herein was derived from the audited Consolidated Financial Statements as of December 31, 2022, but does not include all disclosures required by U.S. GAAP on an annual reporting basis. Certain prior period amounts have been reclassified to conform to the current period presentation.

These Consolidated Financial Statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 6, 2023. Since the date of that filing, there have been no changes or updates to the Company’s significant accounting policies, other than those described below.

In the opinion of management, the Consolidated Financial Statements contain all normal, recurring adjustments necessary for a fair statement of financial position, results of operations, comprehensive loss, and cash flows as of the dates and for the interim periods presented. The results of operations for the three and six months ended June 30, 2023 may not be indicative of the results for the full fiscal year ended December 31, 2023 or any other period.

The Company’s fiscal year is the twelve-month period from January 1 through December 31.

Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues, and expenses reported and disclosures in the financial statements and accompanying notes. Such estimates include, but are not limited to, revenue recognition, valuation of inventory, leases, valuation of intangible and other long-lived assets, recoverability of deferred tax assets, ongoing impairment reviews, and stock-based compensation expense. The Company bases its estimates on historical experience, known trends, market specific information, or other relevant factors it believes to be reasonable.

On an ongoing basis, management evaluates its estimates and changes in estimates are recorded in the period in which they become known. Actual results may differ from these estimates.

Foreign Currency

             The functional currency of the Company’s subsidiaries is their respective local currencies. These subsidiary financial statements are translated into U.S. dollars using the period-end exchange rates for assets and liabilities, average exchange rates during the corresponding period for revenue and expenses, and historical rates for equity. The effects of foreign currency translation adjustments are recorded in accumulated other comprehensive loss within stockholders’ equity on the Consolidated Balance Sheets.

               Foreign currency transaction gains (losses) are included in other income (expense), net on the Consolidated Statements of Operations. Foreign exchange losses were not material during the six months ended June 30, 2023, and were $0.4 million during the six months ended 2022.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Quanterix and its wholly-owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

In accordance with Accounting Standards Codification (“ASC”) 810 – Consolidation, the Company assesses the terms of its investment interests in entities to determine if any meet the definition of a variable interest entity (“VIE”) and require consolidation into its Consolidated Financial Statements. Refer to Note 15 –Variable Interest Entities for further discussion.

Presentation of Restricted Cash

The following table summarizes the period ending cash and cash equivalents as presented on the Consolidated Balance Sheets and the total cash, cash equivalents, and restricted cash as presented on the Consolidated Statements of Cash Flows (in thousands):

	As of June 30,
	2023		2022
Cash and cash equivalents	$	329,525	$	361,293
Restricted cash (1)		2,686		2,594
Cash, cash equivalents, and restricted cash	$	332,211	$	363,887

(1) Restricted cash consists of collateral for a letter of credit issued as security for several of the Company’s leased facilities and to secure the Company’s corporate credit card program. The short-term or long-term classification is determined in accordance with the expiration of the underlying letter of credit and security.

Recent Accounting Pronouncements

There are no new accounting pronouncements issued or effective in the current or future periods that are expected to have a material impact on the Company’s Consolidated Financial Statements or accompanying notes.

Product Revenue

UltraDx

On May 26, 2022, the Company and UltraDx Limited (“UltraDx”), a company formed by ARCH Venture Partners (“ARCH”), entered into an agreement (the “UltraDx Agreement). Under the UltraDx Agreement, the Company agreed to supply UltraDx with HD-X instruments (both fully assembled and disassembled), assays and assay

components, and granted a co-exclusive license to manufacture, seek Chinese regulatory approval of (including performance of any necessary research and development activities), and commercialize, HD-X instruments assembled in China and related assays in the Chinese neurological in vitro diagnostic market. Refer to Note 13 – Related Party Transactions for a discussion of the related party relationships between Quanterix and these entities.

The Company determined that the instruments, components, and licenses formed a single, combined performance obligation. The consideration due to the Company included (1) cash proceeds of $1.9 million, which was received and recognized as revenue in the third quarter of 2022 when the instruments, components, and licenses were delivered to and paid by UltraDx, and (2) contingent, non-cash consideration in the form of ordinary shares of UltraDx with a deemed fair value of $1.0 million. The issuance of the shares was contingent on UltraDx completing a preferred share financing under the terms and conditions in the UltraDx Agreement. Given the uncertainty of the completion of the preferred share financing, the Company concluded that the non-cash consideration related to the ordinary shares was variable consideration that was fully constrained at contract inception.

During the three months ended June 30, 2023, UltraDx completed the qualified preferred share financing and issued to the Company one million ordinary shares with a total fair value of $1.0 million. Refer to Note 5 – Fair Value of Financial Instruments for the Company’s disclosures related to determining the fair value of the shares received. Also refer to Note 15 – Variable Interest Entities for additional information on the Company’s investment interests in UltraDx as a result of the share issuance.

During the three and six months ended June 30, 2023, the Company recognized $1.4 million of revenue, which includes the one-time revenue from the receipt of the UltraDx shares. During the three and six months ended June 30, 2022, no revenue was recognized under the UltraDx Agreement.

Of the performance obligations not yet satisfied or partially satisfied, $10.4 million is expected to be recognized as revenue in the next 12 months, with the remainder expected to be recognized within the 24 months thereafter. The $10.4 million principally consists of amounts billed for undelivered services related to initial and extended service-type warranties and research services.

Costs to Obtain a Contract

The Company capitalizes commissions paid to its sales representatives and related fringe benefits costs that are incremental to obtaining customer contracts. These costs are included in prepaid expenses and other current assets on the Consolidated Balance Sheets. Changes in costs to obtain a contract were as follows (in thousands):

	2023		2022
Balance at December 31 of prior year	$	377	$	440
Deferral of costs to obtain a contract		335		632
Amortization of costs to obtain a contract		(333)		(662)
Balance at June 30	$	379	$	410

Costs to obtain a contract are amortized to earnings over the estimated life of the contract and are recorded in cost of goods sold and selling, general, and administrative expense on the Consolidated Statements of Operations. The Company evaluates potential impairment of these amounts at each balance sheet date, and no related impairments were recorded during the six months ended June 30, 2023 or 2022.

Allowance for Credit Losses

Note 4. Allowance for Credit Losses

The Company is exposed to credit losses primarily through accounts receivable from sales of its products and services. The Company’s expected credit loss allowance methodology is developed using historical collection experience, current and future economic and market conditions, and a review of the status of customers’ accounts receivable.

Customers are assessed for credit worthiness upfront through a credit review, which includes analysis of customers’ financial statements when a credit rating is not available.

The allowance for credit losses on accounts receivable is summarized as follows (in thousands):

Nonrecurring Fair Value Measurements

On June 26, 2023, the Company received ordinary shares in UltraDx (refer to Note 3 – Revenue and Related Matters) which were valued at $1.0 million upon receipt, primarily using the third-party purchase price of similar interests issued during UltraDx’s financing event that closed in the second quarter of 2023. As UltraDx is a recently formed, privately held entity, there is minimal market activity or other financial information available to determine the fair value of UltraDx’s shares and therefore this investment is considered a Level 3 financial asset. Changes in the inputs and assumptions used would have resulted in a higher or lower fair value measurement.

Pursuant to ASC 321 – Investments – Equity Securities, the Company has elected the measurement alternative for equity investments without readily determinable fair values and will continue to recognize the UltraDx shares at cost, less any impairment, and adjusted for any observable price changes in orderly transactions.

As of June 30, 2023 and December 31, 2022, the carrying value of the Company’s Level 3 financial assets was $1.3 million and $0.3 million, respectively. There were no changes in the carrying value of these assets during the three and six months ended June 30, 2023 and 2022. These assets are included in other non-current assets on the Consolidated Balance Sheets. Refer to Note 15 – Variable Interest Entities for further discussion.

Other Fair Value Disclosures

During the six months ended June 30, 2023 and 2022, the Company did not transfer financial assets between levels of the fair value hierarchy. Additionally, there have been no changes to the valuation techniques for Level 3 financial assets.

Employee Stock Purchase Plan (“ESPP”)

In December 2017, the Company adopted the 2017 Employee Stock Purchase Plan (the “2017 ESPP”). The 2017 ESPP contains an “evergreen” provision, which allows for an increase in the number of shares under the plan on the first day of each fiscal year beginning with fiscal year 2018. The increase is equal to the lowest of: (i) 1% of the number of shares of common stock outstanding on the last day of the immediately preceding fiscal year and (ii) an amount determined by the Company’s Board of Directors or Compensation Committee. On January 3, 2023, the number of shares of common stock available for issuance under the 2017 ESPP was increased by 372 thousand shares.

The 2017 ESPP provides for six-month offering periods commencing and ending as follows: March 1 through August 31, and September 1 through February 28. During the six months ended June 30, 2023, employees purchased 70 thousand shares of the Company’s common stock pursuant to the 2017 ESPP.

During the third quarter of 2022, the Company identified certain indicators of impairment, including a significant decline in the Company’s stock price, actions taken under the Restructuring Plan (refer to Note 14 - Restructuring), and a reduction of forecasted sales and profitability. As a result, the Company performed a goodwill impairment test and determined its goodwill was impaired as the carrying amount of the Company’s sole reporting unit exceeded its estimated fair value. The Company concluded that its entire goodwill balance was impaired and recognized an $8.2 million non-cash impairment charge during the third quarter of 2022.

As of June 30, 2023 and December 31, 2022, the Company had no remaining goodwill balance.

Note 14. Restructuring

Following a strategic review and assessment of the Company’s operations and cost structure, on August 8, 2022, the Company announced a restructuring and strategic re-alignment plan (the “Restructuring Plan”). As part of the Restructuring Plan, the Company began an assay redevelopment program with the ultimate objective of improving its ability to manufacture and deliver high-quality assays at scale. The Restructuring Plan aligns the Company’s investments to best serve the needs of its customers, focuses the Company’s innovation efforts on key platforms, and provides a foundation for the Company’s entry into translational pharma and clinical markets, which it believes will be required to access new growth categories. In accordance with the Restructuring Plan, the Company implemented a workforce reduction, which was substantially completed by the end of the third quarter of 2022. The Restructuring Plan included the elimination of 119 positions and other cost-saving measures.

As a result of the Restructuring Plan, the Company performed an impairment assessment of its goodwill, long-lived assets, including operating lease right-of-use assets, and intangibles. The assessments resulted in the Company recording an impairment charge of $25.6 million during the year ended December 31, 2022. The impairment charge included (1) $16.3 million associated with the operating lease right-of-use asset and related property and equipment at leased facilities, (2) $8.2 million of goodwill (refer to Note 11 – Goodwill), and (3) $1.1 million for software costs related to projects that were rationalized as part of the Restructuring Plan. There were no impairment charges recorded associated with the Restructuring Plan during the three and six months ended June 30, 2023. There were no material changes to the Restructuring Plan or the exit and disposal costs in 2023.

Note 15. Variable Interest Entities

The Company enters into relationships with or has investments in other entities that may be VIEs. The Company assesses the criteria in ASC 810 – Consolidation to determine if any of these entities meet the definition of a VIE and require consolidation into its financial statements. The Company’s analysis determines whether it has a controlling financial interest and also identifies the primary beneficiary of a VIE as the enterprise that has both (1) the power to direct activities of a VIE that most significantly impact the entity’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to that entity.

As discussed in Note 3 – Revenue and Related Matters, during the second quarter of 2023 the Company received one million ordinary shares of UltraDx under the UltraDx Agreement. Primarily due to having less than a 5% ownership interest in UltraDx, the Company concluded that it does not have the power to direct activities impacting UltraDx’s economic performance and therefore the Company is not the primary beneficiary of the VIE.

Based on the Company’s assessments, it does not have any controlling financial interests in any VIEs, and therefore did not consolidate any VIEs into its Consolidated Financial Statements during the three and six months ended June 30, 2023 and 2022.

As of June 30, 2023 and December 31, 2022, the carrying value of the Company’s investment interests in VIEs was $1.3 million and $0.3 million, respectively, which are recorded in other non-current assets on the Consolidated Balance Sheets. Refer to Note 5 – Fair Value of Financial Instruments for the Company’s related valuation disclosures. Maximum exposure to losses related to these VIEs is limited to their carrying value and the Company does not have any future funding commitments to these VIEs.

Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with the generally accepted accounting principles in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting on Form 10-Q. Accordingly, certain information and disclosures required for complete financial statements prepared in accordance with U.S. GAAP are not included herein. The Consolidated Balance Sheet included herein was derived from the audited Consolidated Financial Statements as of December 31, 2022, but does not include all disclosures required by U.S. GAAP on an annual reporting basis. Certain prior period amounts have been reclassified to conform to the current period presentation.

These Consolidated Financial Statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 6, 2023. Since the date of that filing, there have been no changes or updates to the Company’s significant accounting policies, other than those described below.

In the opinion of management, the Consolidated Financial Statements contain all normal, recurring adjustments necessary for a fair statement of financial position, results of operations, comprehensive loss, and cash flows as of the dates and for the interim periods presented. The results of operations for the three and six months ended June 30, 2023 may not be indicative of the results for the full fiscal year ended December 31, 2023 or any other period.

The Company’s fiscal year is the twelve-month period from January 1 through December 31.

Use of Estimates

Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenues, and expenses reported and disclosures in the financial statements and accompanying notes. Such estimates include, but are not limited to, revenue recognition, valuation of inventory, leases, valuation of intangible and other long-lived assets, recoverability of deferred tax assets, ongoing impairment reviews, and stock-based compensation expense. The Company bases its estimates on historical experience, known trends, market specific information, or other relevant factors it believes to be reasonable.

On an ongoing basis, management evaluates its estimates and changes in estimates are recorded in the period in which they become known. Actual results may differ from these estimates.
