908 Devices Inc.

1. Nature of the Business and Basis of Presentation

908 Devices Inc. (the “Company”) was incorporated in the State of Delaware on February 10, 2012. The Company is revolutionizing chemical analysis with its simple handheld devices, addressing life-altering applications. The Company’s devices are used at the point-of-need to interrogate unknown and invisible materials and provide quick, actionable answers in vital health, safety and defense tech applications, addressing the fentanyl and illicit drug crisis, toxic carcinogen exposure, and global security threats. The Company designs and manufactures innovative products that bring together the power of complementary analytical technologies, software automation, and machine learning.

The Company is subject to risks and uncertainties common to technology companies in the device industry and of similar size, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, uncertainty of market acceptance of products, and the need to obtain additional financing to fund operations. Potential risks and uncertainties also include, without limitation, uncertainties regarding elevated inflation and interest rates, and changes in countries’ trade policies and tariffs. Products currently under development will require additional research and development efforts prior to commercialization and will require additional capital and adequate personnel and infrastructure. The Company’s research and development may not be successfully completed, adequate protection for the Company’s technology may not be obtained, and approved products may not prove commercially viable. The Company operates in an environment of rapid change in technology and competition.

Acquisitions

The Company acquired KAF Manufacturing Company, Inc. (“KAF”), located in Stamford, Connecticut in July 2025. KAF is a precision machining company focused on providing precision components, diamond-turned optics and components for laboratory and medical instrument original equipment manufacturers and for the aerospace industry. This acquisition provided the Company with strength and sustainability over its supply chain for critical Fourier Transform Infrared (“FTIR”) components. See Note 15,Acquisitions, for further information.

Divestment of Desktop Portfolio

The Company sold its wholly-owned subsidiary, 908 Devices GmbH and certain liabilities and specified assets of the Company which together constituted the entirety of the Company’s portfolio of desktop devices used in the field of bioprocessing Process Analytical Technology (the “Desktop Portfolio”) to Repligen Corporation and Repligen GmbH (“Repligen Corporation” or “Repligen”) on March 4, 2025 (the “Closing Date”). See Note 3,Discontinued Operation, for further information.

On the Closing Date, the Company entered into a Transition Services Agreement (the “TSA”) with Repligen, which provides for services to be performed by the Company in order to facilitate a transition of the business associated with the Desktop Portfolio. Under the TSA, the Company provided certain technology, financial, manufacturing and other operational transition services to Repligen for a period of time, and will maintain the personnel and facilities required to provide such services for the duration specified for each such service. Repligen has agreed to pay the Company for certain costs of the transition services performed by the Company under the TSA and these services are recorded within Other Income, net in the Company’s condensed consolidated statement of operations.

On the Closing Date, the parties entered into a Lease Assignment Assumption and Consent Agreement (the “Assignment and Assumption Agreement”). Under the Assignment and Assumption Agreement, the Company assigned to Repligen the Company’s rights in, to and under the real property lease for its North Carolina facility, and Repligen assumed the liabilities related thereto. In addition, as a result of the sale of 908 Devices GmbH, Repligen assumed the liabilities related to the real property lease in Braunschweig, Germany.

On the Closing Date, the Company entered into an UNC Intellectual Property Sublicense Agreement with Repligen (the “Sublicense Agreement”) under which the Company granted a sublicense to license certain Company rights to in-licensed

technologies under the Company’s license agreement with the University of North Carolina (“UNC”). See Note 14,Commitments and Contingencies.

On the Closing Date, the company entered into a Supply Agreement with Repligen under which the Company will supply certain components to Repligen related to the Rebel product offering.

The Company incurred certain significant costs relating to the divesture, such as legal, accounting, financial advisory, printing and other professional services fees, as well as other customary payments. Through March 31, 2025, these costs amounted to approximately $4.0 million and are included within the net income (loss) from discontinued operations, net of tax line item on the Company's condensed consolidated statement of operations.

Unaudited Interim Financial Information

The accompanying condensed consolidated financial statements have been prepared based on continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. The Company has incurred recurring losses since inception, including net losses from continuing operations of $12.0 million for the three months ended March 31, 2026 and $33.3 million for the year ended December 31, 2025. As of March 31, 2026, the Company had an accumulated deficit of $235.3 million. The Company expects to continue to generate operating losses for the foreseeable future. The Company expects that its cash, cash equivalents, marketable securities and revenue from product and service will be sufficient to fund its operating expenses and capital expenditure requirements for at least 12 months from the issuance date of the condensed consolidated financial statements. The Company may seek additional funding through private or public equity financings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into collaborations or other arrangements. The terms of any financing may adversely affect the holdings or the rights of the Company's stockholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product expansion or commercialization efforts, or the Company may be unable to continue operations.

Basis of Presentation

The Company’s consolidated financial statements have been prepared in conformity with GAAP. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, 908 Devices Securities Corporation and CAM2 Technologies, LLC (d/b/a RedWave Technology) (“RedWave”). All intercompany balances and transactions have been eliminated.

Reclassifications

The Company’s Desktop Portfolio met all the conditions to be classified as held for sale and, because the Company considers the disposal of the Desktop Portfolio to be a strategic shift that will have a major effect on its operations and financial results, represented a discontinued operation. Further, all historical operating results for the Company’s Desktop Portfolio are reflected within discontinued operations in the condensed consolidated statements of operation for all periods presented. For additional information, see Note 3,Discontinued Operations and TSA.

Certain amounts in prior periods have been reclassified to reflect the impact of the discontinued operations treatment of the Desktop Portfolio in order to conform to the current period presentation.

2. Summary of Significant Accounting Policies

Unaudited Condensed Interim Financial Information

The condensed consolidated balance sheet at December 31, 2025 was derived from audited consolidated financial statements but does not include all disclosures required by GAAP. The accompanying unaudited condensed consolidated

financial statements as of March 31, 2026 and for the three months ended March 31, 2026 and 2025 have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 on file with the SEC. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s financial position as of March 31, 2026 and results of operations for the three months ended March 31, 2026 and 2025 and statements of stockholders’ equity for the three months ended March 31, 2026 and 2025 and cash flows for the three months ended March 31, 2026 and 2025 have been made. The Company’s results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2026 or any other period.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, revenue recognition and accounts receivable, the valuation of inventory, fair value of assets acquired and liabilities assumed in acquisitions, fair value of contingent consideration, and the valuation of stock-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Due to the impact of elevated inflation and interest rates, and changes in countries’ trade policies and tariffs and changes in interest rates, there has been uncertainty and disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require further updates to its estimates or judgments or a revision of the carrying value of its assets or liabilities as of the date of issuance of these condensed consolidated financial statements. These estimates may change, as new events occur and additional information is obtained. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.

Risk of Concentrations of Credit, Significant Customers and Significant Suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. The Company’s cash and cash equivalents and restricted cash are maintained in bank deposit accounts and money market funds that regularly exceed federally insured limits. The Company is exposed to credit risk on its cash, cash equivalents and restricted cash in the event of default by the financial institutions to the extent account balances exceed the amount insured by the Federal Deposit Insurance Corporation (“FDIC”). The Company’s marketable securities are invested in U.S. treasury securities and as a result, the Company believes represent minimal credit risk.

Significant customers are those that accounted for 10% or more of the Company’s total revenue or accounts receivable. One customer represented 14% of total revenue for the three months ended March 31, 2026 andthree customers represented 14%,13% and 10% of total revenue for the three months ended March 31, 2025. As of March 31, 2026, two customers accounted for 24% and 23% of gross accounts receivable, respectively. As of December 31, 2025, one customer accounted for 34% of gross accounts receivable.

Certain of the components included in the Company’s products are obtained from a sole source, a single source or a limited group of suppliers. Although the Company seeks to reduce dependence on those limited sources of suppliers and manufacturers, the partial or complete loss of certain of these sources, or the requirement to establish a new supplier for the components, could have a material adverse effect on the Company’s operating results, financial condition and cash flows and damage its customer relationships.

Accounts** **Receivable

Accounts receivable are presented net of an allowance for credit losses, which is an estimate of amounts that may not be collectible. The Company performs ongoing credit evaluations of its customers and monitors economic conditions to identify facts and circumstances that may indicate its receivables are at risk of not being collected. The Company provides reserves against accounts receivable for estimated credit losses, if any, that may result from a customer’s inability to pay based on the composition of its accounts receivable, current economic conditions and historical credit loss activity, and relevant available forward-looking information. Amounts deemed uncollectible are charged or written-off against the reserve. The following is a summary of the activity of the Company’s allowance for credit losses (in thousands):

Revenue from Contracts with Customers

The Company’s customers primarily consist of federal and defense entities, state authorities and local municipalities, foreign national and provincial organizations and other institutions.

Distribution Channels

A majority of the Company’s revenue is generated by sales in conjunction with its channel partners, such as its international channel partners and, in the United States, for end customers where a government contract is required or a customer has a pre-existing relationship. When the Company transacts with a channel partner, its contractual arrangement is with the partner and not with the end-use customer. Whether the Company transacts business with and receives the order from a channel partner or directly from an end-use customer, its revenue recognition policy and resulting pattern of revenue recognition for the order are the same.

Disaggregated Revenue

The Company’s product and service revenue consists of sales of devices and recurring revenue which includes consumables, accessories and the sale of service and extended warranty plans. The following table presents the Company’s revenue by revenue stream (in thousands):

Customer Commitment

In June 2025, the Company entered into a Master Supply Agreement with a large analytical instrumentation customer (“OEM Customer”), who is an existing customer of the Company and a customer of KAF. The OEM Customer committed to $6.6 million of orders over the initial three years with a minimum initial cancelation fee of $2.6 million. In addition, in July 2025, the OEM Customer paid an upfront cash payment of $0.75 million to secure the supply of precision optical components and assemblies and the fee will be recognized over the initial term of the Master Supply Agreement. As of March 31, 2026, $0.6 million of the upfront payment is recorded in deferred revenue and deferred revenue, net of current portion.

Deferred Revenue

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03,Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures(Subtopic 220-40): Disaggregation of Income Statement Expenses. The new standard requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of the ASU on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In July 2025, the FASB issued ASU 2025-05,Financial Instruments—Credit Losses (Topic 326) to introduce a practical expedient to calculating current expected credit loss by assuming that the current conditions as of the balance sheet date will not change for the remaining life of the asset. This expedient can only be applied to current accounts receivable and current contract assets. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025 and interim periods within those annual periods, and this update is applied prospectively. The Company adopted ASU 2025-05 in the first quarter of 2026 and applied it prospectively, with no material impact on its consolidated financial statements.

3. Discontinued Operation and TSA

On March 3, 2025, upon board approval of the transaction, the Company classified its Desktop Portfolio as held for sale, and the Company then completed the sale of its Desktop Portfolio to Repligen on March 4, 2025. The Company has determined the sale of the Desktop Portfolio represents a strategic shift that will have a major effect on its business and therefore met the criteria for classification as discontinued operations as of March 3, 2025.

The related assets and liabilities of the Desktop Portfolio were classified as assets and liabilities of discontinued operations in the consolidated balance sheets and the results of operations from the Desktop Portfolio as discontinued operations in the consolidated statements of operations. Applicable amounts in prior years have been recast to conform to this discontinued operations presentation.

As of March 31, 2026 and December 31, 2025, there wereno assets or liabilities of discontinued operations, as the Company completed the sale of its Desktop Portfolio to Repligen on March 4, 2025.

The following table presents the gain on the sale of the Desktop Portfolio as of March 31, 2025, pursuant to the Securities and Asset Purchase Agreement by and between the Company and Repligen, dated as of the Closing Date (the “Repligen Purchase Agreement”) (in thousands):

For the three months ended March 31, 2026 and 2025, the Company recognized no gain and a $56.6 million gain, net of tax, respectively, within net income from discontinued operations on the Company’s condensed consolidated statements of operations.

The following table presents the financial results of the discontinued operations prior to the sale of the Desktop Portfolio (in thousands):

In accordance with ASC 205-20, only expenses specifically identifiable and related to a business to be disposed may be presented in discontinued operations. As such, the research and development and general and administrative expenses in discontinued operations only include corporate costs incurred directly to support the Desktop Portfolio.

The Company has also entered into a TSA with Repligen, through which the Company provided certain technology, financial, manufacturing and other operational transition services to Repligen for a period of time, and maintained the personnel and facilities required to provide such services for the duration specified for each such service. Income from TSA, net of directly identifiable costs, is included as income from transition services agreement, net under other income, net. The majority of the services and obligations under the TSA were concluded as of the third quarter of 2025.

As of March 31, 2026, Repligen owes the Company $0.4 million related to the payments and collection services provided under the TSA as of March 31, 2026.

The cash flows related to discontinued operations have not been segregated and are included in the condensed consolidated statements of cash flows. For the three months ended March 31, 2025, capital expenditures related to the Desktop Portfolio were less than $0.1 million. Depreciation and amortization expense related to the Desktop Portfolio for the same period was $0.3 million. Share based compensation expense for the same period was $0.1 million. Excluding the gain of $56.6 million recognized on the sale of the Desktop Portfolio presented in the condensed consolidated statements of cash flows for the three months ended March 31, 2025, there were no other material operating or investing non-cash items related to the Desktop Portfolio for either period presented.

4. Fair Value Measurements

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

Money Market Funds

Money market funds were valued by the Company based on quoted market prices, which represent a Level 1 measurement within the fair value hierarchy. There were no transfers between Level 1, Level 2 or Level 3 during the three months ended March 31, 2026 or 2025.

Marketable Securities

U.S. Treasury securities were valued by the Company using quoted prices in active markets for similar securities, which represent a Level 2 measurement within the fair value hierarchy.

Contingent Consideration

The Company recognizes acquisition-related contingent consideration which represents the estimated fair value of future payments or issuance of the Company’s common stock to the former owners of an acquired entity as part of certain transactions. Acquisition-related contingent consideration is measured and reported at fair value using the present value technique, the Monte Carlo simulation method or probability weighted scenario based on the unobservable inputs, which are significant to the fair value and classified with Level 3 of the fair value hierarchy.

For the acquisition of RedWave in April 2024, the amount of contingent consideration to be issued is contingent based on the amount of revenue the Company generates from the sale of certain RedWave products and services during thetwo-year period from May 1, 2024 through April 30, 2026. As of the acquisition date of RedWave, the fair value of the contingent consideration was estimated using a Monte Carlo simulation, utilizing the closing price of the Company’s common stock on the Nasdaq Global Market of$5.76 per share, revenue projections, an equity volatility rate of the Company of 90%, a revenue volatility rate of 30% and a discount rate of 26.5%.

As of March 31, 2026, the fair value of the contingent consideration related to the acquisition of RedWave was estimated utilizing revenue recognized from May 1, 2024 through March 31, 2026, projected revenue for April 2026, projected backlog expected as of April 30, 2026 and the closing price of the Company’s common stock of$6.12 per share as of March 31, 2026.

The Company achieved the minimum threshold of the sale of certain RedWave products and services as of March 31, 2026. The following table provides a roll-forward of the fair value of the Company’s contingent consideration, for which fair value is determined using Level 3 inputs (in thousands):

The change in the fair value of contingent consideration liability is included in loss from continuing operations.

9. Restructuring

In June 2025, the Company abandoned its Boston facility in connection with transitioning manufacturing operations from Boston, Massachusetts to Danbury, Connecticut and moved its corporate headquarters to Burlington, Massachusetts. The Company had no intention to sublease or utilize the space for the remaining lease term, resulting in the right-use assets to be abandoned. The Company recorded a $1.0 million restructuring charge for the lease abandonment, including its remaining right-of-use asset, utilities and other costs. The Company made full payment of such charges in June 2025, including the rents. The organizational and facility restructurings were substantially completed in June 2025.

10. Long-Term Debt

Loan Revolver

On March 5, 2026, the Company entered into the Amended 2026 Revolver by and between the Company, as borrower, and SVB, as lender. The Amended 2026 Revolver provides for a revolving line of credit of up to $20.0 million. The Amended 2026 Revolver supersedes and replaces the Amended 2022 Revolver and its extension upon the execution of the Amended 2026 Revolver. The Company is permitted to make interest-only payments on the revolving line of credit through March 5, 2028, at which time all outstanding indebtedness shall be immediately due and payable. The outstanding principal amount of any advance shall accrue interest at a floating rate per annum equal to the greater of (i) six percent (6.00%) or (ii) the “prime rate” as published in The Wall Street Journal. The Company’s obligations under the Amended 2026 Revolver are secured by substantially all of the Company’s assets, excluding its intellectual property, which is subject to a negative pledge. The Company capitalized $0.1 million of the debt issuance cost upon entering into the Amended 2026 Revolver andno balance is drawn from the revolving line of credit as of March 31, 2026.

11. Equity and Net Income (Loss) per Share

Equity

As of March 31, 2026, the Company’s certificate of incorporation authorized the Company to issue up to 5,000,000 shares of preferred stock, all of which is undesignated.

Each share of common stock entitles the holder toone vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are not entitled to receive dividends, unless declared by the board of directors.

As of March 31, 2026, and December 31, 2025, the Company had outstanding warrants for the purchase of 92,703 shares of common stock at an exercise price of $9.17 per share, of which warrants for the purchase of 49,078 shares and 43,625 shares expire in 2027 and 2028, respectively. The warrants are recorded within stockholders’ equity.

Net (Loss) Income per Share

Basic and diluted net (loss) income per share attributable to common stockholders was calculated as follows (in thousands, except share and per share data):

The Company utilizes the control number concept in the computation of diluted earnings per share to determine whether potential common stock equivalents are dilutive. The control number used is net loss from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. Since the Company had a net loss from continuing operations for all periods presented, no dilutive effect has been recognized in the calculation of income from discontinued operations per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss from continuing operations and net (loss) income from discontinued operations per share attributable to common stockholders are the same.

Diluted net (loss) income per common share is computed by dividing net (loss) income by the weighted average number of shares of common stock outstanding for the period, including potential dilutive common shares assuming the dilutive effect of outstanding warrants, stock options, restricted stock units and shares to be purchased under the Company’s employee stock purchase plan.

For periods in which the Company reports a net loss from continuing operations, regardless of net (loss) income from discontinued operation, diluted net (loss) income per share attributable to common stockholders is the same as basic net (loss) income per share attributable to common stockholders since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. As the Company has reported a net loss from continuing operations during the three months ended March 31, 2026 and 2025, basic net (loss) income per share is the same as diluted net loss per share.

The Company excluded the following potential shares of common stock, presented based on amounts outstanding at each period end, from the computation of diluted net (loss) income per share attributable to common stockholders for the three months ended March 31, 2026 and 2025 as the impact of including such common stock equivalents would have been anti-dilutive:

12. Stock-Based Compensation

The Company recorded stock-based compensation expense for all stock awards in the following expense categories of its condensed consolidated statements of operations (in thousands):

As of March 31, 2026, there was $12.0 million of unrecognized compensation cost related to unvested restricted stock units (“RSUs”) that is expected to be recognized over a weighted average period of 2.2 years.

The maximum payout percentage for all performance-based restricted stock units, including Market Condition Based PSUs and Performance Condition Based PSUs, granted by the Company is 100%.

As of March 31, 2026, there was less than $0.1 million of unrecognized compensation cost related to unvested Market Condition Based PSUs and Performance Condition Based PSUs that is expected to be recognized over a weighted average period of 0.1 years.

2026 Inducement Plan

In February 2026, the Company adopted the 2026 Inducement Plan (the “Inducement Plan”). The Inducement Plan was adopted by board of directors without stockholder approval pursuant to Nasdaq Marketplace Rule 5635(c)(4) (Rule 5635(c)4)). In accordance with Rule 5635(c)(4), awards made under the Inducement Plan, including stock options and RSUs, may only be granted to newly hired employees as a material inducement to accept employment with the Company. Awards granted under the Inducement Plan expire no later thanten years from the date of grant. An aggregate of 1,000,000 shares of common stock were reserved for issuance under the Inducement Plan. No shares were granted under the Inducement Plan during the three months ended March 31, 2026.

13. Leases

The Company’s primary operating lease obligations consist of leases for office space and manufacturing facilities in Massachusetts and Connecticut.

The Company has leases for office space and certain equipment. Some of the leases include options to extend the lease for up to ten years and these options were not included for the purpose of determining the right-of-use assets and associated lease liabilities as the Company determined that the renewal of these leases is not reasonably certain. The leases do not include any restrictions or covenants that had to be accounted for under the lease guidance. All of the leases recorded on the consolidated balance sheets as ROU assets are operating leases.

In July 2025, the Company acquired KAF and entered into an agreement to lease the approximately 11,500 rentable square feet facility in Stamford, Connecticut. The lease commenced in December 2025 for a term of 25 months with total lease costs of approximately $0.4 million.

In June 2025, the Company entered into a new operating lease agreement in Burlington, Massachusetts. The new lease is for approximately 13,000 rentable square feet and commenced in June 2025 for a term of 50 months with total lease costs of approximately $1.9 million. The Company abandoned its facility in Boston, Massachusetts to relocate the Company’s headquarters and research and development activities to the new Burlington location. See Note 9,Restructuring.

In February 2025, the Company entered into a new operating lease agreement in Massachusetts to relocate the machine shop from the Company’s headquarters to a lower cost location. The new lease is for approximately 3,500 rentable square feet and commenced in March 2025 for a term of 60 months with total lease costs of approximately $0.2 million.

For additional information, read Note 16,*Leases,*to the consolidated financial statements in the Company’s Form 10-K for the year ended December 31, 2025.

The components of lease expense under ASC 842,* Leases*, were as follows (in thousands):

Supplemental disclosure of cash flow information related to leases was as follows (in thousands):

The weighted-average remaining lease term and discount rate were as follows:

The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

Future annual minimum lease payments under operating leases as of March 31, 2026 are as follows (in thousands):

14. Commitments and Contingencies

Royalty Arrangements

The Company has entered into royalty arrangements whereby the Company owes low- to mid-single digit royalty percentages related to revenue that is derived pursuant to in-licensed technologies. These royalties are calculated as a percent of

revenue or on a per component basis, depending on the arrangement. Royalty obligations are expensed when incurred or over the minimum royalty periods and have not been material.

As a part of Repligen Purchase Agreement, the Company entered into a sublicense agreement with Repligen under which the Company granted a sublicense to certain Company rights to in-licensed technologies under the Company’s license agreement with UNC. Under the sublicense agreement, Repligen owes the Company low- to mid-single digit royalty percentages related to revenue that is derived pursuant to such licensed technologies, which are calculated as a percent of revenue. See Note 1,Nature of the Business and Basis of Presentation.

401(k) Savings Plan

The Company has a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code of 1986. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of the board of directors. During the three months ended March 31, 2026 and 2025, the Company made $0.2 million and $0.2 million, respectively, in contributions to the plan.

Contingent Consideration – Earnouts

15. Acquisitions

Acquisition of KAF Manufacturing Company, Inc.

On July 1, 2025, the Company entered into an asset purchase agreement with KAF. The purchase price included an initial payment of $2.0 million in cash, and a contingent obligation to pay an additional $0.75 million in cash in six months following the closing of the transaction if certain operating requirements have been satisfied in accordance with the terms of the asset purchase agreement. The transaction closed on July 1, 2025, at which time certain KAF assets were acquired and 15 employees were hired by the Company.

KAF is a precision machining company focused on providing precision components, diamond-turned optics and components for laboratory and medical instrument original equipment manufacturers and for the aerospace industry. The Company believes this acquisition will enable it to strengthen and secure its supply chain for critical FTIR components.

The preliminary purchase price allocation related to the acquisition of KAF is complete. The Company has retained an independent valuation firm to assess the fair value of the identified intangible assets and certain tangible assets acquired.

The Company has accounted for the acquisition of KAF as a business combination under U.S. GAAP. Under the acquisition method of accounting, the assets of KAF have been recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company.

In June 2025, the Company entered into a Master Supply Agreement with an OEM Customer, who is an existing customer of the Company and a customer of KAF. On July 1, 2025, the Company also entered into a lease agreement, which includes extension options under the Company’s control through March 2028, with the KAF owners for the 11,500 rentable square feet building in Stamford, Connecticut. In accordance with ASC 805-10-25-20 through 25-22, these contractual arrangements were accounted separately from the business combination. See Note 13,Leases for further information.

The Company has allocated the purchase price to the net tangible and intangible assets based on their estimated fair values as of July 1, 2025.

The results of KAF’s operations have been included in the Company’s consolidated financial statements since the date of the acquisition. Pro forma financial information reflecting the acquisition has not been presented because the impact, individually and collectively, on revenues and net income (loss) is not material.

Fair Value of Net Assets Acquired

Subsequent to the acquisition date, no measurement period adjustments were recognized. The following table presents the primary allocation of the consideration paid on the acquisition date for the KAF transaction (amounts in thousands):

In December 2025, the $0.75 million contingent consideration was paid following the satisfaction of the certain operating requirements in accordance with the terms of the asset purchase agreement.

The fair value of standard tools and machinery was determined using the cost approach which includes assumptions related to replacement cost, physical deterioration, economic obsolescence, and scrap value, or the market approach which includes adjustments for physical condition of comparable standard tools or machinery sold. The fair value of the customer

relationships was calculated using a distributor method, a form of the income approach, which incorporates a variation of the multi-period excess earnings method that uses market-based inputs to value an asset. Under this method, the value of the asset is a function of several components, including revenue associated with the existing customers, distributor profit margin, charges for use of other assts and discount rate. Intangible assets acquired have finite life and are amortized per our accounting policy. See Part II, Item 8,Summary of Significant Accounting Policies, of our 2025 Form 10-K, for the amortization periods.

16. Segment Reporting

The Company has determined that it operates and is managed asone operating segment on a consolidated basis and its Chief Executive Officer is the CODM (see Part II, Item 8 of our 2025 Form 10-K). The Company’s CODM is regularly provided with research and development expenses, sales and marketing expenses, general and administrative expenses and total assets. The Company’s segment performance measure is net income (loss), which is used by our CODM when assessing performance and allocating capital and resources to our business.

The CODM uses total revenues and operating results, predominantly in the strategic plan, annual operating plan and quarterly forecast review processes. During these processes, the CODM considers budget-to-actual variances to evaluate both internal (e.g., changes in selling prices, strategic growth investments, productivity, business mix, newly acquired/divested businesses, etc.) and external (e.g., inflation, foreign currency, etc.) events and conditions.

The following table includes additional information about reported segment revenue, significant segment expenses and segment measure of profitability (in thousands):

17. Subsequent events

Acquisition of NIRLAB SA

On May 4, 2026 (the “Closing Date”), the Company completed its acquisition of NIRLAB SA, a corporation organized under the laws of Switzerland (“NIRLAB”), and its wholly owned subsidiary, NIRLAB Forensics Sàrl, a limited liability company organized under the laws of Switzerland (together with NIRLAB, the “NIRLAB Group”), pursuant to a Share Purchase Agreement (the “Purchase Agreement”) with Florentin Coppey, Pierre Esseiva, Matteo Delbrück, Parkview Invest AG and Matthieu Girod (each a “Seller” and collectively, the “Sellers”) and NIRLAB. The NIRLAB Group develops near-infrared spectroscopy solutions for instant material identification. Under the Purchase Agreement, the Sellers sold all outstanding registered shares of NIRLAB (the "NIRLAB Shares"), constituting the entire issued share capital of NIRLAB, to the Company.

Pursuant to the Purchase Agreement, the Sellers agreed to sell and transfer to the Company, on the Closing Date, all of the issued and outstanding NIRLAB Shares in exchange for a preliminary consideration payable by the Company on the Closing Date with a headline price of $15,000,000, comprised of (x) $13,000,000 in cash (the “Cash Consideration”) and (y)293,368 shares of common stock of the Company, par value $0.001 per share (the “Stock Consideration”).

The Cash Consideration is subject to customary adjustments. The Company withheld $1,300,000 of the Cash Consideration and 10% of the Stock Consideration (together, the “General Holdback Amount”) to secure the Sellers’ post-closing obligations under the Purchase Agreement. Subject to any outstanding claims, the General Holdback Amount shall be released to the Sellers twelve (12) months after the Closing Date.

The Company will account for the acquisition of NIRLAB as a business combination under U.S. GAAP. Under the acquisition method of accounting, the assets of NIRLAB will be recorded as of the acquisition date, at their respective fair values, and consolidated with those of the Company.

As of May 6, 2026, the preliminary purchase price allocation related to the acquisition of NIRLAB is incomplete due to timing of the acquisition. The Company has retained an independent valuation firm to assess the fair value of the identified intangible assets and certain tangible assets acquired and liabilities assumed.
