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 $24.5 million as of June 30, 2024 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, Long-Term 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 June 30, 2024 and December 31, 2023:

(in thousands)		June 30, 2024				December 31, 2023
Derivatives Instruments	Balance Sheet Classification	Notional Amount		Fair Value (a)		Notional Amount		Fair Value (a)

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 June 30, 2024 and for the three and six months ended June 30, 2024 and 2023 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, 2023 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 unaudited 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, 2023.

In the opinion of management, all adjustments, which include normal recurring adjustments necessary to present a fair statement of financial position as of June 30, 2024, results of operations and comprehensive income (loss) for the three and six months ended June 30, 2024 and 2023, and cash flows for the six months ended June 30, 2024 and 2023, as applicable, have been made. The results of operations for the three and six months ended June 30, 2024, are not necessarily indicative of the operating results for the full fiscal year or any future periods.

The accounting policies underlying the accompanying unaudited 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, 2023. There have been no material changes in the Company’s significant accounting policies during the six months ended June 30, 2024.

Use of Estimates

The preparation of financial statements in conformity with generally 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 evaluate the value for inventories reported at 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 reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.

Other Operating Expenses

The components of other operating expenses for the three and six months ended June 30, 2024 were as follows:

	Three Months Ended			Six Months Ended
(in thousands)	June 30, 2024			June 30, 2024
Restructuring expenses (see Note 15)	$	396		$	396
Unclaimed property audits (credit) expense (see Note 13)		(147	)		347
Employee retention credit fees (see Note 5)		-			472
Total other operating expenses	$	249		$	1,215

Recently Issued Accounting Pronouncements Yet to Be Adopted

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax, 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 ended December 31, 2025. The Company is currently evaluating the potential impact of adopting ASU No. 2023-09 will have on the disclosures in its consolidated financial statements.

Stock-Based Compensation

Stock-based compensation expense for the three and six months ended June 30, 2024 and 2023 was allocated as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2024		2023		2024		2023

Total stock-based compensation expense	$	1,278	$	1,102	$	2,326	$	2,255

As of June 30, 2024, the total compensation costs related to unvested awards not yet recognized was $7.8 million and the weighted average period over which it is expected to be recognized is approximately 2.0 years. The Company did not capitalize any stock-based compensation.

Restricted stock unit (“RSU”) activity for the six months ended June 30, 2024 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

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 up 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.

Stock option activity for the six months ended June 30, 2024 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, 2023		924,067		$	3.37

Outstanding and exercisable at June 30, 2024		896,953		$	3.35		3.00	$	91

The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $2.85 as of the last trading day of the reporting period, which would have been received by the option holders had all option holders exercised their options as of that date. The aggregate intrinsic value of options exercised during the six months ended June 30, 2024, was not significant.

Restructuring and Other Exit Costs

On an ongoing basis, the Company reviews the global economy, the healthcare industry, and the markets in which it competes to identify operational efficiencies, enhance commercial capabilities and align its cost base and infrastructure with customer needs and its strategic plans. In order to realize these opportunities, the Company undertakes activities from time to time to transform its business. A portion of these transformation activities are considered restructuring costs under ASC 420, Exit or Disposal Cost Obligations, and are discussed below.

During the three and six months ended June 30, 2024, the Company completed a restructuring and incurred expenses of $0.4 million, primarily consisting of severance incurred in connection with headcount reductions in Europe and North America. The changes in the accrued liability for restructuring and other charges for the six months ended June 30, 2024 were as follows:

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.

The income tax benefit was $0.4 million and $1.1 million for the three months ended June 30, 2024 and 2023, respectively, and was $0.1 million and $0.5 million for the six months ended June 30, 2024 and 2023, respectively. The Company’s effective tax rates of 10.8% and 1.8% for the three and six months ended June 30, 2024, respectively, were lower than the U.S. statutory rate primarily due to the inclusion of non-deductible executive compensation and changes in valuation allowances associated with the Company’s assessment of the likelihood of the recoverability of deferred tax assets. The Company’s effective tax rates of 53.3% and 59.8% for the three and six months ended June 30, 2023 were higher than the U.S. statutory rate primarily due to a Global Intangible Low-Taxed Income (“GILTI”) inclusion to taxable income and changes in valuation allowances. The Company has valuation allowances against substantially all of its tax credit carryforwards.

Long-Term Debt [Text Block]

8.	Long-Term Debt

As of June 30, 2024 and December 31, 2023, the Company’s borrowings were as follows:

(in thousands)	June 30, 2024			December 31, 2023
Long-term debt:
Term loan	$	26,700		$	30,723
Revolving line		9,400			6,400
Less: unamortized deferred financing costs		(420	)		(560	)
Total debt		35,680			36,563
Less: current portion of long-term debt		(4,000	)		(6,139	)
Current unamortized deferred financing costs		280			280
Long-term debt	$	31,960		$	30,704

The Company maintains a Credit Agreement (as amended, the “Credit Agreement”) with Citizens Bank, N.A., Wells Fargo Bank, National Association, and First Citizens Bank & Trust Company (together, the “Lenders”). The Credit Agreement provides for a term loan of $40.0 million and a $25.0 million senior 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 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 Credit Facility. The Company’s obligations under the Credit Agreement are secured by substantially all of the assets of Harvard Bioscience, Inc., and each guarantor (including all or a portion of the equity interests in certain of the Company’s domestic and foreign subsidiaries). Issuance costs of $1.4 million are amortized over the contractual term to maturity date on a straight-line basis, which approximates the effective interest method. Available and unused borrowing capacity under the revolving line of credit was $5.4 million as of June 30, 2024, based on the Credit Agreement, as amended on August 6, 2024 (the “August 2024 Amendment”), as described below. Total revolver borrowing capacity is limited by the consolidated net leverage ratio as defined under the amended Credit Agreement.

Borrowings under the Credit Facility will, 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”), or (ii) an alternative base rate plus an applicable interest rate margin, each as determined as provided in the Credit Agreement (an “ABR Loan”). SOFR interest under the Credit Agreement is subject to applicable market rates and a floor of 0.50%. 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 August 2024 Amendment, the applicable interest rate margin varies from 2.0% per annum to 3.75% per annum for SOFR Loans, and from 1.5% per annum to 3.5% per annum for ABR Loans, in each case depending on the Company’s consolidated net leverage ratio, and is determined in accordance with a pricing grid set forth in the Credit Agreement. 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 borrowings for the three months ended June 30, 2024 and 2023, was 7.9% and 8.3%, respectively, and for the six months ended June 30, 2024 and 2023, was 7.8% and 8.1%, respectively. The weighted average interest rate as of June 30, 2024, net of the effect of the Company’s interest rate swaps, was 7.7%. 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.

As of June 30, 2024, the term loan requires quarterly installment payments of $1.0 million with a balloon payment at maturity on December 22, 2025. Furthermore, within ninety days after the end of the Company’s fiscal year, the term loan may be permanently reduced pursuant to certain mandatory prepayment events including an annual “excess cash flow sweep”, as defined in the Credit Agreement, provided that, in any fiscal year, any voluntary prepayments of the term loan shall be credited against the Company’s “excess cash flow” prepayment obligations on a dollar-for-dollar basis for such fiscal year. As of December 31, 2023, the current portion of long-term debt included amounts due under the excess cash flow sweep of $2.0 million which was paid on March 29, 2024. Amounts outstanding under the revolving credit facility can be repaid at any time but are due in full at maturity.

The Credit Agreement includes customary affirmative, negative, and financial covenants binding on the Company. The negative covenants limit the ability of the Company, among other things, to incur debt, incur liens, make investments, sell assets and 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.

In March 2024, the Company entered into an amendment to the Credit Agreement pursuant to which the Lenders and administrative agent modified the definition of Consolidated EBITDA used in the calculation of certain financial covenants to adjust for charges related to an abandoned property audit (see Note 13) and commission fees expected to be paid in connection with the ERC filings (see Note 5).

On August 6, 2024, the Company entered into an amendment to the Credit Agreement that, among other things, modifies the financial covenants relating to the consolidated net leverage ratio and consolidated fixed charge coverage ratio through the period ended December 31, 2024. The amendment also adds a net leverage ratio requirement with respect to additional borrowing under the Company’s revolving credit facility and restrictions on certain additional indebtedness and investments, in each case until the Company delivers to the Lenders the Company’s financial statements for the fiscal year ending December 31, 2024. In addition, until delivery of the financial statements, the applicable interest rate margin will be increased by 50bps during such time as the Company’s consolidated net leverage ratio is greater than 3.0. The Company paid fees of $0.2 million to the Lenders in connection with the amendment. As a result of the August 2024 Amendment, the Company is in compliance with the financial covenants of the Credit Agreement.

The Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”) provided an employee retention credit (“ERC”) 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 analogy to 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 ERC refunds of $3.2 million during the six months ended June 30, 2024. Due to the subjectivity of the credit, the Company has included the refunds received in other current liabilities in the consolidated balance sheet as of June 30, 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 ERC refunds and accumulating the necessary support that was used as a basis in the filing. During the six months ended June 30, 2024, the Company paid fees of $0.5 million for these services, which are included in other operating expenses in the consolidated statement of operations.

Earnings Per Share [Text Block]

2.	Earnings (Loss) per Share

Basic earnings (loss) per share (EPS) is calculated by dividing net income (loss) by the number of weighted average shares of common stock outstanding during the period. The calculation of diluted earnings per share assumes conversion of stock options and restricted stock units into common stock using the treasury method, unless the effect is antidilutive.

The following table summarizes the calculation of basic and diluted net loss per share of common stock:

Commitments and Contingent Liabilities

The Company is involved in various claims and legal proceedings arising in the ordinary course of business. After consultation with legal counsel, the Company has determined that the ultimate disposition of such proceedings is not likely to have a material adverse effect on its business, financial condition, results of operations or cash flows. Although unfavorable outcomes in the proceedings are possible, the Company has not accrued loss contingencies relating to any such matters as they are not considered to be probable and reasonably estimable. If one or more of these matters are resolved in a manner adverse to the Company, the impact on the Company’s business, financial condition, results of operations and cash flows could be material.

In addition, the Company has entered into indemnification agreements with its directors and officers. It is not possible to determine the maximum potential liability amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. The Company has not recorded any liability for costs related to contingent indemnification obligations as of June 30, 2024.

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 a credit of $(0.1) million and an expense of $0.3 million during the three and six months ended June 30, 2024, respectively, related to unclaimed property audits which have been included in other operating expenses in the consolidated statement of operations.
