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 and three 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.

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.
