Derivatives and Fair Value [Text Block]

9.	Derivatives

In February 2023, the Company entered into an interest rate swap contract to improve the predictability of cash flows from interest payments related to its variable, SOFR-based debt. The swap contract had a notional amount of $17.6 million as of September 30, 2025 and matures on December 22, 2025. This swap contract effectively converts the SOFR-based variable portion of the interest payable under the Credit Agreement into fixed-rate debt at an annual rate of 4.75%. The swap contract does not impact the additional interest related to the applicable interest rate margin as discussed above in Note 8, Debt.

The swap contract is considered an effective cash flow hedge, and as a result, net gains or losses are reported as a component of other comprehensive income (“OCI”) in the consolidated financial statements and are reclassified when the underlying hedged interest impacts earnings. An assessment is performed quarterly to evaluate the ongoing hedge effectiveness.

The following table presents the notional amount and fair value of the Company’s derivative instruments as of September 30, 2025 and December 31, 2024:

(in thousands)		September 30, 2025					December 31, 2024

(a) See Note 10 for the fair value measurements related to these financial instruments.

The effect of the cash flow hedge on other comprehensive income (loss) and earnings for the periods presented was as follows:

Contract Liabilities

The following table provides details of contract liabilities as of the periods indicated:

	September 30,		December 31,
(in thousands)	2025		2024		Change			Percentage
Deferred revenue
Service, maintenance and warranty contracts	$	1,414	$	1,560	$	(146	)		-9	%
Installation and training		477		806		(329	)		-41	%
Customer advances		988		1,440		(452	)		-31	%
Total short-term contract liabilities		2,879		3,806		(927	)		-24	%
Long-term service, maintenance and warranty contracts		288		-		288			100	%
Total contract liabilities	$	3,167	$	3,806	$	(639	)		-17	%

Changes in the Company’s contract liabilities are primarily due to the timing of receipt of payments under service, maintenance and warranty contracts and lower sales volumes. Additionally, customer advances have decreased due to the recognition of amounts under the Company’s exchange program, which allows customers to purchase a replacement implantable monitor of the same model at a lower price than a new monitor if the customer returns an implantable monitor to the Company after use, and the returned monitor can be reprocessed and resold. During the three months ended September 30, 2025 and 2024, the Company recognized revenues of $0.4 million and $0.4 million from contract liabilities existing at December 31, 2024 and 2023, respectively. During the nine months ended September 30, 2025 and 2024, the Company recognized revenue of $3.2 million and $3.0 million from contract liabilities existing at December 31, 2024 and 2023, respectively.

The following table represents the Company's remaining performance obligations from contracts that are recognized over time as of September 30, 2025:

Income Tax Disclosure [Text Block]

Income Tax

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which the Company operates and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, the Company’s tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

Income tax expense (benefit) was $0.1 million and $0.3 million for the three months ended September 30, 2025 and 2024, respectively, and was ($0.3) million and $0.2 million for the nine months ended September 30, 2025 and 2024, respectively. The Company’s effective tax rate of (8.6)% and 0.6% for the three and nine months ended September 30, 2025, respectively, were lower than the U.S statutory rate due to the tax effect of goodwill impairment. The Company’s effective tax rates of (6.9)% and (1.4)% for the three and nine months ended September 30, 2024, respectively, were different than the U.S. statutory rate primarily due to the inclusion of non-deductible executive compensation. The effective tax rate for both periods was also impacted by changes in valuation allowances associated with the Company’s assessment of the likelihood of the recoverability of deferred tax assets.

On July 4, 2025, subsequent to the end of the second quarter of fiscal 2025, the One Big Beautiful Bill Act (the “Act”) was signed into law. The Act includes several significant tax-related provisions, including the permanent extension of certain elements of the Tax Cuts and Jobs Act. The legislation features staggered effective dates beginning in 2025 and continuing through 2027. The Company has incorporated the provisions from the Act into the Q3 2025 income tax provision and has concluded that these changes did not have a significant impact on its consolidated financial statements and related disclosures.

The entire disclosure for income tax.

1.	Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

The unaudited consolidated financial statements of Harvard Bioscience, Inc. and its wholly-owned subsidiaries (collectively, the “Company”) as of September 30, 2025, and for the three and nine months ended September 30, 2025 and 2024, have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. The December 31, 2024, consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

In the opinion of management, all adjustments, which include normal recurring adjustments necessary to present a fair statement of financial position as of September 30, 2025, results of operations and comprehensive loss for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024, as applicable, have been made. The results of operations for the three and nine months ended September 30, 2025, are not necessarily indicative of the anticipated operating results for the full year ending December 31, 2025, or any future periods.

The accounting policies underlying the accompanying condensed consolidated financial statements are set forth in Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes in the Company’s significant accounting policies during the nine months ended September 30, 2025.

Going Concern

The unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2025, have been prepared assuming that the Company will continue as a going concern. A going-concern basis assumes that the Company will continue its operations for the foreseeable future and contemplate the realization of assets and the settlement of liabilities in the normal course of business. As noted below, there is substantial doubt about the Company’s ability to continue as a going concern.

As of September 30, 2025, there was indebtedness of $34.0 million outstanding under the Company's term loan and senior revolving credit facility (collectively, the “Credit Agreement”). On August 8, 2025, the Company entered into an amendment (the “August 2025 Amendment”) to the Credit Agreement, pursuant to which the Lenders (defined below) and administrative agent agreed, subject to the terms contained in the August 2025 Amendment, to waive the events of default under the Credit Agreement due to the Company’s failure to achieve certain refinancing milestones (the “Refinancing Milestones”) and its failure to comply with certain financial covenants. In connection with the August 2025 Amendment, the Company has agreed to accomplish steps towards the refinancing (the “Refinancing”) or repayment of the Credit Agreement by no later than December 5, 2025. The Company continues to make progress on these steps, and is working actively to reach a definitive agreement that will accomplish one of these outcomes. The failure to accomplish such steps on the agreed timeline shall constitute an event of default under the Credit Agreement. In such event, in addition to other actions the lenders may require, the amounts outstanding under the Credit Agreement may become immediately due and payable.

The Company continues to explore alternative sources of capital that would allow it to refinance the outstanding indebtedness due under the Credit Agreement, but its ability to access such other sources of capital is uncertain. There is no assurance that such capital will be available, be obtainable on commercially acceptable terms, or provide the Company with sufficient funds to meet its objectives. Based on its anticipated cash flows from operations, unless the Company is able to access other sources of capital or extend the date for repayment under the Credit Agreement, the Company will be unable to pay its debt obligations and fund its operations for at least twelve months from the date of issuance of the condensed consolidated financial statements contained in this Quarterly Report on Form 10-Q. As a result, there is substantial doubt about the Company's ability to continue as a going concern.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires the use of management estimates. Such estimates include the determination and establishment of certain accruals and provisions, including those for income taxes, credit losses on receivables, and defined benefit pension obligations. Estimates are also required to assess the value for inventories reported at the lower of cost or net realizable value, stock-based compensation expense, and the recoverability of long-lived and intangible assets, including goodwill. On an ongoing basis, the Company assesses its previous estimates based upon currently available information. Actual results could differ materially from the estimates.

Other Operating Expenses

The components of other operating expenses for the three and nine months ended September 30, 2025 and 2024 were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2025		2024		2025		2024

Recently Issued Accounting Pronouncements Yet to Be Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax (“ASU No. 2023-09”), which enhances disclosures related to the effective tax rate reconciliation, income taxes paid, as well as other disclosures. The new standard impacts footnote disclosures and is effective for the Company’s annual financial statements for the year ending December 31, 2025. The Company is continuing to assess the impact adopting ASU No. 2023-09 will have on the footnote disclosures in its consolidated financial statements.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement (Subtopic 220-40): Reporting Comprehensive Income—Expense Disaggregation Disclosures (“ASU No. 2024-03”), which requires enhanced disclosure of income statement expense categories to improve transparency and provide financial statement users with more detailed information about the nature, amount and timing of expenses impacting financial performance. This new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is continuing to assess the impact adopting ASU No. 2024-03 will have on the footnote disclosures in its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), requiring election of a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted in both interim and annual reporting periods. The Company is evaluating the impact that ASU 2025-05 will have on its consolidated financial statements.

Restructuring Costs

On an ongoing basis, the Company reviews the global economy, the life sciences industry, and the markets in which it competes to identify operational efficiencies and align its cost base and infrastructure with customer needs and its strategic plans. In order to achieve these goals, the Company undertakes activities from time to time to optimize its business.

During the nine months ended September 30, 2025, the Company initiated additional restructurings for which it incurred $0.2 million of costs, primarily consisting of severance incurred in connection with headcount reductions in North America and Europe. The Company expects the restructuring to be completed during the year ending December 31, 2025.

During the nine months ended September 30, 2024, the Company completed a restructuring and incurred expenses of $0.6 million, primarily consisting of severance incurred in connection with headcount reductions in North America and Europe. Severance and other costs have been included as a component of other operating expenses (see Note 1). The changes in the accrued liability for restructuring and other charges for the nine months ended September 30, 2025 were as follows:

Debt

The Company’s debt, which was included within current liabilities as of September 30, 2025 and December 31, 2024, was as follows:

(in thousands)	September 30, 2025			December 31, 2024

Total debt	$	33,967		$	36,956

The Company maintains a Credit Agreement with Citizens Bank, N.A., Wells Fargo Bank, N.A., and First-Citizens Bank & Trust Company (the “Lenders”). The Credit Agreement originally provided for a term loan of $40.0 million and a $25.0 million revolving credit facility (including a $10.0 million sub-facility for the issuance of letters of credit and a $10.0 million swingline loan sub facility) (collectively, the “Credit Facility”). The Company’s obligations under the Credit Agreement are secured by substantially all of its assets, including all or a portion of the equity interests in certain of the Company’s domestic and foreign subsidiaries. The Company’s obligations under the Credit Agreement are guaranteed by certain of the Company’s direct, domestic wholly owned subsidiaries; none of the Company’s direct or indirect foreign subsidiaries has guaranteed the Company’s obligations under the Credit Agreement. Issuance costs of $2.0 million are amortized over the contractual term to maturity date on a straight-line basis, which approximates the effective interest method. Total revolver borrowing capacity is limited by the consolidated net leverage ratio as defined under the amended Credit Agreement. As of the date of these financial statements, the Company was unable to make additional borrowings under its revolving credit facility due to net leverage ratio requirements set forth in the August 6, 2024 amendment to the Credit Agreement and the terms of the March 10, 2025 amendment to the Credit Agreement (the “March 2025 Amendment”), as described below.

Borrowings under the Credit Facility, at the option of the Company, bear interest at either (i) a rate per annum based on the Secured Overnight Financing Rate (“SOFR”) for an interest period of one, two, three or six months, plus an applicable interest rate margin determined as provided in the Credit Agreement (a “SOFR Loan”), subject to a floor of 0.50%, or (ii) an alternative base rate plus an applicable interest rate margin, each as determined as provided in the Credit Agreement. The alternative base rate is based on the Citizens Bank prime rate or the federal funds effective rate of the Federal Reserve Bank of New York and is subject to a floor of 1.0%. Pursuant to the March 2025 Amendment, the applicable interest rate margin was increased such that interest rate was equal to a rate per annum based on the SOFR plus 400 bps effective as of March 10, 2025. There are no prepayment penalties in the event the Company elects to prepay and terminate the Credit Facility prior to its scheduled maturity date, subject to SOFR Loan breakage and redeployment costs in certain circumstances.

The effective interest rate on the Company’s borrowings for the three months ended September 30, 2025 and 2024, was 11.0% and 8.7%, respectively, and for the nine months ended September 30, 2025 and 2024 was 9.4% and 8.1%, respectively. The weighted average interest rate as of September 30, 2025, net of the effect of the Company’s interest rate swap agreement, was 10.0%. The carrying value of the debt approximates fair value because the interest rate under the obligation approximates market rates of interest available to the Company for similar instruments.

The term loan required quarterly installment payments of $1.0 million with a balloon payment at maturity on December 22, 2025. Pursuant to the March 2025 Amendment, amortization payments were revised so that a proportionate payment must be made on a monthly rather than a quarterly basis.

The Credit Agreement includes various customary financial covenants and other affirmative and negative covenants binding on the Company. The negative covenants limit the ability of the Company, among other things, to incur debt, permit liens, make investments, sell assets, or pay dividends on its capital stock. The financial covenants include a maximum consolidated net leverage ratio and a minimum consolidated fixed charge coverage ratio. The Credit Agreement also includes customary events of default.

The March 2025 Amendment provided, among other things, that the Lenders’ commitment under the revolving credit facility would be capped at $12.65 million, which was the amount outstanding thereunder as of the date thereof, and thus we are unable to make additional borrowings under our revolving credit facility. The March 2025 Amendment also established certain Refinancing Milestones in connection with the Refinancing, including, by June 30, 2025, the closing of the Refinancing. The Lenders also agreed not to assert any breaches of the financial covenants included in the Credit Agreement for the first quarter of 2025 provided that the Company continued to comply with its payment obligations, achieved the Refinancing Milestones, maintained minimum liquidity (defined as the sum of (a) unrestricted cash and cash equivalents and (b) the amount by which the aggregate amount committed under the Company’s revolving credit facility exceeds the total amount drawn under the credit facility) of $3.5 million and provided the administrative agent with certain financial reports.

As of June 30, 2025, the Company was not in compliance with the Refinancing Milestones and quarterly financial covenants included in the March 2025 Amendment. On August 8, 2025, the Company entered into the August 2025 Amendment, pursuant to which the Lenders and administrative agent agreed, subject to the terms contained in the August 2025 Amendment, to waive the events of default due to the Company’s failure to achieve certain Refinancing Milestones and its failure to comply with the consolidated net leverage ratio covenant and the consolidated fixed charge coverage ratio covenant as of the June 30, 2025 test date. Pursuant to the terms of the August 2025 Amendment, the Lenders also agreed not to test the net leverage ratio financial covenant and the consolidated fixed charge coverage ratio financial covenant for the fiscal quarter ended September 30, 2025, and to reduce the Company’s covenant to maintain minimum liquidity (defined as the sum of (a) unrestricted cash and (b) the amount by which the aggregate amount committed under the Company’s revolving credit facility exceeds the total amount drawn under the credit facility) of $3.0 million.

The August 2025 Amendment also added, as a mandatory prepayment event, the receipt of cash proceeds upon a Refinancing or upon the sale of the equity interests or all or substantially all of the assets of the Company. In addition, pursuant to the terms of the August 2025 Amendment, the applicable interest rate margin was increased such that the interest rate is equal to a rate per annum based on the SOFR plus 700 bps. In connection with the August 2025 Amendment, the Company has agreed to accomplish steps towards the Refinancing or repayment of the Credit Agreement by no later than December 5, 2025. The Company continues to make progress on these steps, and is working actively to reach a definitive agreement that will accomplish one of these outcomes. The failure to accomplish such steps on the agreed timeline shall constitute an event of default under the Credit Agreement.

The Company agreed to pay fees of $0.4 million, or 1.00% of the outstanding debt, to the Lenders in connection with the August 2025 Amendment, of which 25% was paid upon the signing of the August 2025 Amendment and the remaining 75% will be payable upon a Refinancing or repayment of the Credit Agreement or upon the occurrence of an event of default.

Segment Information

The Company conducts business as a single operating segment, which is based upon the Company’s organizational and management structure, as well as information used by the chief operating decision maker (“CODM”) to allocate resources and other factors. The key measure of segment profitability that the CODM uses to allocate resources and assess performance is consolidated net income (loss), as reported on the consolidated statements of operations. The CODM utilizes consolidated net loss by comparing actual results against budgeted amounts on a quarterly basis. The following table presents the significant revenue and expense categories of the Company’s single operating segment:

	Three Months Ended September 30,						Nine Months Ended September 30,

Goodwill and Intangible Assets Disclosure [Text Block]

4.	Goodwill and Long-Lived Assets

The Company determined that a sustained decrease in its stock price that occurred during the three months ended March 31, 2025 indicated that the carrying values of its goodwill and other long-lived assets may not be recoverable. Additional factors that contributed to this conclusion are the Company’s recent operating results, liquidity risk and the current macroeconomic conditions impacting the life sciences industry. Based on this determination, the Company performed interim quantitative impairment tests on its goodwill and other long-lived assets as of March 31, 2025 and June 30, 2025, as well as a qualitative analysis as of September 30, 2025.

The recoverability of assets or an asset group to be held and used is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset or the asset group. Based on its recoverability assessment, the Company determined that there was no impairment of its other long-lived assets as of March 31, 2025 and June 30, 2025. Based on its qualitative analysis the Company determined that there was no impairment of its other long-lived assets as of September 30, 2025.

For the purpose of its goodwill impairment analysis, the Company has one reporting unit. The Company estimated the fair value of the reporting unit using an income-based valuation approach by means of a discounted cash flow (“DCF”) model. Under this model, the fair value of the reporting unit is determined based on the present value of estimated future cash flows, discounted at a risk-adjusted rate of return. The Company used internal forecasts and strategic long-term plans to estimate future cash flows, including projections of revenue and EBITDA, capital expenditure and working capital requirements, terminal growth rates, statutory tax rates and a market-participant discount rate. The goodwill impairment analysis also includes a reconciliation of the aggregate estimated fair value of the reporting unit to the Company’s total market capitalization. Based on this quantitative impairment analysis as of March 31, 2025, the Company determined that the carrying value of the reporting unit exceeded its fair value by $48.0 million. Accordingly, the Company recorded such amount as a goodwill impairment charge for the three months ended March 31, 2025. Based on the quantitative impairment analysis performed as of June 30, 2025 and qualitative analysis performed as of September 30, 2025, an additional impairment charge was not required during the three months ended June 30, 2025, and September 30, 2025.

The inputs and assumptions used in determining the fair value of the reporting unit are subjective and require management’s use of significant judgment. Certain future events and circumstances, including further deterioration of the Company’s stock price, operating results, and macroeconomic conditions, and a higher cost of capital, among others, could result in changes to these inputs and assumptions. A revision of these inputs and assumptions could cause the fair value of the reporting unit to fall further below its carrying value, resulting in additional impairment charges, which could have a material adverse effect on the Company’s results of operations.

The change in the carrying amount of goodwill for the nine months ended September 30, 2025 was as follows:

Commitments and Contingent Liabilities

The Company is occasionally subject to claims and lawsuits which typically arise in the normal course of business. While the outcome of these claims cannot be predicted with certainty, management does not believe that the outcome of any of these legal matters will have a material adverse effect on the Company’s business, results of operations, financial condition, or cash flows.

The Company is subject to unclaimed property laws in the ordinary course of its business. State escheat laws generally require entities to report and remit abandoned and unclaimed property to the state. Failure to timely report and remit the property can result in assessments that could include interest and penalties, in addition to the payment of the escheat liability itself. The Company recorded an expense of $0.3 million during the nine months ended September 30, 2024 related to unclaimed property audits which have been included in other operating expenses in the consolidated statement of operations. The unclaimed property audit was completed during the second quarter of fiscal 2024.

Stock-Based Compensation

Stock-based compensation expense for the three and nine months ended September 30, 2025 and 2024 was allocated as follows:

	Three Months Ended September 30,					Nine Months Ended September 30,
(in thousands)	2025		2024			2025		2024
Cost of revenues	$	18	$	(30	)	$	79	$	88
Sales and marketing expenses		122		164			346		453
General and administrative expenses		104		795			703		2,493
Research and development expenses		80		124			268		345
Total stock-based compensation	$	324	$	1,053		$	1,396	$	3,379

As of September 30, 2025, the total compensation costs related to unvested awards not yet recognized was $1.8 million and the weighted average period over which such costs are expected to be recognized is approximately 1.7 years. The Company did not capitalize any stock-based compensation.

Restricted stock unit (“RSU”) activity for the nine months ended September 30, 2025 was as follows:

						Market-					Performance-
	Time-Based					Based					Based
	Restricted			Grant Date		Restricted			Grant Date		Restricted			Grant Date
	Stock Units			Fair Value		Stock Units			Fair Value		Stock Units			Fair Value
Balance at December 31, 2024		1,378,995		$	3.51		558,958		$	2.61		375,895		$	4.19
Granted		1,237,821			0.45		500,000			0.67		-			-

Forfeited		(369,499	)		3.56		(192,473	)		2.61		(211,815	)		4.19
Balance at September 30, 2025		1,711,172		$	1.27		866,485		$	1.49		164,080		$	4.19

The aggregate fair value of RSUs that vested during the nine months ended September 30, 2025, and 2024 was $0.3 million and $0.5 million, respectively. Unvested shares related to market-based and performance-based vesting conditions are reflected at 100% of their target vesting amount in the table above. Actual vesting could range from zero to 150% of their target amounts.

Performance-based RSU awards are contingent on the achievement of certain performance metrics. Compensation cost associated with performance-based RSUs are recognized based on the estimated number of shares that the Company ultimately expects will be earned. If the estimated number of shares to be earned is revised in the future, then stock-based compensation expense will be adjusted accordingly.

The weighted average estimated fair value of the market condition restricted stock awards that were granted during the nine months ended September 30, 2025 was $0.67 per unit. The estimate of the fair value was determined using a Monte-Carlo valuation simulation, which included the following assumptions:

Volatility	89.8	%
Risk-free interest rate	3.7	%
Correlation coefficient	36.5	%
Dividend yield	-	%

Stock option activity for the nine months ended September 30, 2025 was as follows:

	Number of Options			Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term		Aggregate Intrinsic Value (in thousands)
Outstanding and exercisable at December 31, 2024		827,458		$	3.24
Cancelled/Forfeited		(660,755	)		3.20
Outstanding and exercisable at September 30, 2025		166,703		$	3.39		2.4	$	-

There is no aggregate intrinsic value at September 30, 2025 because the Company’s closing stock price of $0.44 is below the exercise price of the outstanding options.

Earnings Per Share [Text Block]

2.	Earnings (Loss) per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the periods presented. The computation of diluted earnings (loss) per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and other potentially dilutive securities using the treasury stock method unless the effect is antidilutive. The following table summarizes the calculation of basic and diluted net loss per share of common stock:

The Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “CARES Act”) provided an employee retention tax credit (“ERTC”) that was a refundable tax credit against certain employer taxes. The Company elected to account for the credit as a government grant. As there is no authoritative guidance under U.S. GAAP on accounting for grants to for-profit business entities from government entities, the Company accounts for government assistance by applying the principles of International Accounting Standards Topic 20, Accounting for Government Grants and Disclosure of Government Assistance (“IAS 20”). Under IAS 20, government grants are recognized when there is reasonable assurance that the grant will be received and that all conditions related to the grant will be met.

The Company received ERTC refunds of $2.2 million and $3.2 million during the nine months ended September 30, 2025 and 2024, respectively. The Company has included the refunds received in other current liabilities in the consolidated balance sheets as of September 30, 2025 and 2024, subject to a determination that the refunds are recognizable.

The Company engaged a professional services firm under a commission fee arrangement to assist with determining the Company’s eligibility to claim the ERTC refunds and accumulating the necessary support that was used as a basis in the filing. The Company paid fees of $0.3 million and $0.5 million during the nine months September 30, 2025 and 2024, respectively, for these services, which are included in other operating expenses in the consolidated statement of operations.
