Derivatives and Fair Value [Text Block]

7.	Derivatives

The Company monitors interest rate risk attributable to both its outstanding and forecasted debt obligations by the use of cash flow sensitivity analysis, which estimates the expected impact of changes in interest rates on the Company’s future cash. The Company uses interest-rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not enter into derivative instruments for any purpose other than cash flow hedging.

By using derivative financial instruments to hedge exposure to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty and, therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with carefully selected major financial institutions based upon their credit profile.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The market risk associated with interest-rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. The Company monitors interest rate risk attributable to both its outstanding and forecasted debt obligations by the use of cash flow sensitivity analysis, which estimates the expected impact of changes in interest rates on the Company’s future cash flows.

On February 28, 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 has a notional amount of $30.3 million as of June 30, 2023 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 6, Long-Term Debt. The interest rate swap is considered an effective cash flow hedge, and as a result, the net gains or losses on such instrument are reported as a component of other comprehensive income (loss) (“OCI”) in the consolidated financial statements and are reclassified as net income when the underlying hedged interest impacts earnings. A qualitative and quantitative assessment over the hedge effectiveness is performed on a quarterly basis unless facts and circumstances indicate that the hedge may no longer be highly effective.

The following table presents the notional amount and fair value of the Company’s derivative instrument as of June 30, 2023:

The weighted average estimated fair value of the market condition restricted stock awards that were granted during the six months ended June 30, 2023 was $2.61 per unit. The estimate of the fair value was determined using a Monte-Carlo valuation simulation, which included the following assumptions:


Volatility	56.8	%
Risk-free interest rate	4.6	%
Correlation coefficient	41.7	%
Dividend yield	-	%

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. The weighted average number of shares used to compute basic and diluted EPS consisted of the following:

	Three Months Ended June 30,					Six Months Ended June 30,

Significant Accounting Policies (Policies)	Jun. 30, 2023
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	*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, 2023 and for the three and six months ended June 30, 2023 and 2022, 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, 2022, 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, 2022. 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, 2023, results of operations and comprehensive income (loss) and cash flows for the three and six months ended June 30, 2023 and 2022, as applicable, have been made. The results of operations for the three and six months ended June 30, 2023, 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, 2022. Except as described below, there have been no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2023.
Marketable Securities, Policy [Policy Text Block]	*Marketable Equity Securities* Equity securities traded in active markets are marked to market at each balance sheet date based on their prices as quoted on the relevant stock exchange. Fair value mark-to-market adjustments are recorded as non-operating gains (losses) in the consolidated statement of operations. The Company’s investments in marketable equity securities are classified in the consolidated balance sheet based on the nature of the securities and their availability for use in current operations.
Risks and Uncertainties Policy [Policy Text Block]	*Risks and Uncertainties* The global supply chain has experienced significant disruptions over the last few years due to electronic component and labor shortages and other macroeconomic factors which have emerged since the onset of COVID-19. This has led to increased cost of freight, purchased materials, and manufacturing labor costs, while also delaying customer shipments. Additionally, the global economy has recently experienced increasing economic uncertainty, including inflationary pressure, rising interest rates, and significant fluctuations in exchange rates. These conditions have negatively impacted the Company’s past business, results of operations, and cash flow. The Company believes that these global economic uncertainties will continue through 2023. If these factors are prolonged or are more severe than anticipated, the Company’s business, results of operations, and cash flow may be materially impacted.

Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]

1.	Basis of Presentation and Summary of Significant Accounting Policies, and Risks and Uncertainties

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, 2023 and for the three and six months ended June 30, 2023 and 2022, 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, 2022, 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, 2022.

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, 2023, results of operations and comprehensive income (loss) and cash flows for the three and six months ended June 30, 2023 and 2022, as applicable, have been made. The results of operations for the three and six months ended June 30, 2023, 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, 2022. Except as described below, there have been no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2023.

Marketable Equity Securities

Equity securities traded in active markets are marked to market at each balance sheet date based on their prices as quoted on the relevant stock exchange. Fair value mark-to-market adjustments are recorded as non-operating gains (losses) in the consolidated statement of operations. The Company’s investments in marketable equity securities are classified in the consolidated balance sheet based on the nature of the securities and their availability for use in current operations.

Risks and Uncertainties

The global supply chain has experienced significant disruptions over the last few years due to electronic component and labor shortages and other macroeconomic factors which have emerged since the onset of COVID-19. This has led to increased cost of freight, purchased materials, and manufacturing labor costs, while also delaying customer shipments. Additionally, the global economy has recently experienced increasing economic uncertainty, including inflationary pressure, rising interest rates, and significant fluctuations in exchange rates. These conditions have negatively impacted the Company’s past business, results of operations, and cash flow. The Company believes that these global economic uncertainties will continue through 2023. If these factors are prolonged or are more severe than anticipated, the Company’s business, results of operations, and cash flow may be materially impacted.

Note 11 - Income Tax

6 Months Ended

Jun. 30, 2023

Income Tax Disclosure [Text Block]

11.

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 (benefit) expense is $(1.1) million and $1.0 million for the three months ended June 30, 2023 and 2022, respectively, and is $(0.5) million and $0.8 million for the six months ended June 30, 2023 and 2022, respectively. The effective tax rates for the three months ended June 30, 2023 and 2022, are 53.3% and 28.8%, respectively. The effective tax rates for the six months ended June 30, 2023 and 2022, are 59.8% and (23.6)%, respectively.

The difference between the Company’s effective tax rates in 2023 and 2022 compared to the U.S. statutory tax rate of 21% is primarily due to a Global Intangible Low-Taxed Income (“GILTI”) inclusion to taxable income and changes in valuation allowances associated with the Company’s assessment of the likelihood of the recoverability of deferred tax assets. The Company has valuation allowances against substantially all of its net operating loss carryforwards and tax credit carryforwards.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Long-Term Debt [Text Block]

6.	Long-Term Debt

As of June 30, 2023 and December 31, 2022, the Company’s borrowings are as follows:

(in thousands)	June 30, 2023			December 31, 2022
Long-term debt:
Term loan	$	32,223		$	34,814
Revolving line		9,900			12,850

Current unamortized deferred financing costs		280			280
Long-term debt	$	38,203		$	43,013

In December, 2020, the Company entered into a Credit Agreement (the “Credit Agreement”) with Citizens Bank, N.A., Wells Fargo Bank, National Association, and Silicon Valley Bank (together, the “Lenders”). All commitments and obligations under the Credit Agreement previously held by Silicon Valley Bank have now been assumed by First-Citizens Bank & Trust Company. 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). The Credit Facility matures on December 22, 2025. 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 $12.4 million as of June 30, 2023 based on the Credit Agreement, as amended. Total revolver borrowing capacity is limited by the consolidated net leverage ratio as defined under the amended Credit Agreement.

Borrowings under the amended 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, as amended (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%. The applicable interest rate margin varies from 2.0% per annum to 3.25% per annum for SOFR Loans, and from 1.5% per annum to 3.0% per annum for ABR Loans, in each case depending on the Company’s consolidated leverage ratio and is determined in accordance with a pricing grid set forth in the Credit Agreement. Interest on SOFR Loans is payable in arrears on the last day of each applicable interest period, and interest on ABR Loans is payable in arrears at the end of each calendar quarter. 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, 2023 and 2022, was 8.3% and 4.0%, respectively, and for the six months ended June 30, 2023 and 2022, was 8.1% and 3.6%, respectively. The weighted average interest rate as of June 30, 2023, inclusive of the effect of the Company’s interest rate swaps, was 8.1%. 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 amortizes in quarterly installments of $0.75 million per quarter for each of the next two quarters and $1.0 million per quarter during the next seven quarters thereafter, with a balloon payment at maturity. 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” of 50% of the consolidated excess cash flow, as defined in the agreement; provided that, in any fiscal year, any voluntary prepayments of the term loans 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, 2022, the current portion of long-term debt included an excess cash flow sweep of $1.1 million which was paid during the quarter ended March 31, 2023. Amounts outstanding under the revolving credit facility can be repaid at any time but are due in full at maturity.

The Credit Agreement, as amended, 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, as amended, also includes customary events of default.

On April 28, 2022, the Company entered into an amendment to the Credit Agreement (the “April 2022 Amendment”) pursuant to which the Lenders and administrative agent, among other things, modified the financial covenant relating to the consolidated net leverage ratio, and consented to the Biostage Settlement (as defined below), including without limitation the receipt by the Company of convertible preferred stock in Biostage, Inc. (“Biostage”) and the securities issuable upon conversion thereof, as partial payment for Biostage’s indemnification obligations in connection with the Biostage Settlement. See Note 13 for information regarding the Biostage Settlement. In consideration for the April 2022 Amendment, the Company paid fees of $0.2 million to the Lenders and administrative agent.

On November 8, 2022, the Company entered into a subsequent amendment to the Credit Agreement (the “November 2022 Amendment”) pursuant to which, among other things the Lenders and administrative agent modified the financial covenant relating to the consolidated net leverage ratio, and the definition of Consolidated EBITDA used in the calculation of certain financial covenants, including to exclude non-cash inventory charges related to the Company’s decision to discontinue non-strategic products. In consideration for the November 2022 Amendment, the Company paid fees of $0.2 million to the Lenders and administrative agent. The Company was in compliance with the covenants of the Credit Agreement, as amended, as of June 30, 2023.

Litigation Settlement

On April 14, 2017, representatives for the estate of an individual plaintiff filed a wrongful death complaint with the Suffolk Superior Court, in the County of Suffolk, Massachusetts, against the Company and other defendants, including Biostage, a former subsidiary of the Company that was spun off in 2013, as well as another third party (the “Biostage Litigation”). The complaint sought payment for an unspecified amount of damages and alleged that the plaintiff sustained terminal injuries allegedly caused by products, including one synthetic trachea scaffold and two bioreactors, provided by certain of the named defendants and utilized in connection with surgeries performed by third parties in Europe in 2012 and 2013.

On April 27, 2022, the Company and Biostage executed a settlement with the plaintiffs of the Biostage Litigation and Biostage’s products liability insurance carriers (the “Biostage Settlement”), which resolved all claims by and between the parties and Biostage’s product liability insurance carriers and resulted in the dismissal with prejudice of the wrongful death claim and all claims between the Company, Biostage and the insurance carriers. The Biostage Settlement was entered into solely by way of compromise and settlement and is not in any way an admission of liability or fault by the Company or Biostage. Biostage has indemnified the Company for all losses and expenses, including legal expenses that the Company incurred in connection with the Biostage Litigation and the Biostage Settlement.

During the three months ended March 31, 2022, the Company accrued $5.2 million of costs related to legal fees and the Biostage Settlement. Due to the financial condition of Biostage, the Company determined that it was uncertain as to whether Biostage would be able to meet its indemnification obligation and had fully reserved any receivable from Biostage.

During the three months ended June 30, 2022, the Company recorded credits of $4.9 million to the reserve against the indemnification receivable from Biostage. These adjustments reflected: i) the issuance by Biostage of 4,000 shares of its Series E Convertible Preferred Stock (the “Series E Preferred Stock”) to the Company on June 10, 2022, in satisfaction of $4.0 million of Biostage’s total indemnification obligation, ii) the payment by Biostage of the legal fees associated with the Biostage Settlement, and iii) other accrual adjustments. The Series E Preferred Stock accrued dividends at a rate of 8% per annum that are payable in additional shares of Series E Preferred Stock. The Series E Preferred Stock was initially recorded at an estimated fair value of $3.9 million using a Monte Carlo valuation simulation incorporating information from selected guideline companies.

As of December 31, 2022, the book value of the shares of Series E Preferred Stock, inclusive of accrued dividends, was $4.0 million and was included in the consolidated balance sheet as a component of Other long-term assets. The Company elected the provisions within ASC 321, Investment Securities, to subsequently measure the Series E Preferred Stock at its original cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of Biostage. As of December 31, 2022, there were no observable price changes or indicators of impairment and therefore, there was no measurement adjustments to the carrying value of the Series E Preferred Stock.

On January 18, 2023, the Company voluntarily converted 200 shares of its Series E Preferred Stock into 31,933 shares of Biostage common stock.

On April 6, 2023, Biostage disclosed that it had completed a private placement of its common stock for an aggregate offering amount of approximately $6.0 million at a purchase price of $6.00 per share. As the proceeds of the private placements were in excess of $4.0 million, the transaction triggered a mandatory conversion of the Company’s remaining Series E Preferred Stock into shares of Biostage common stock at the offering price of $6.00 per share. As of June 30, 2023, the Company held 707,626 shares of Biostage common stock with an estimated fair value of $2.6 million, which has been included in the consolidated balance sheet as a component of Other long-term assets due to the limited trading volumes of Biostage’s common stock on the OTCQB Marketplace.

The Company determines the fair value of its shares of Biostage common stock at each reporting period using prices as quoted on the OTCQB Marketplace. Due to Biostage’s limited operating history, its overall financial condition and the limited trading volumes and liquidity of its common stock, the value of the Company’s investment in Biostage’s common stock could fluctuate considerably or become worthless. During the three months ended June 30, 2023, the Company recorded unrealized losses related to its investment in Biostage common stock of $1.6 million, which was recorded in the Other expense section in the consolidated statements of operations.

Accounting Standards Update and Change in Accounting Principle [Text Block]

2.	Recently Issued Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The Company adopted ASU 2016-13 effective January 1, 2023 with no impact to the consolidated financial statements. The Company will perform future goodwill impairment test according to ASU 2017-04.

In September 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The FASB issued several ASUs after ASU 2016-13 to clarify implementation guidance and to provide transition relief for certain entities. The Company adopted ASU 2016-13 effective January 1, 2023, which resulted in an immaterial impact to the consolidated financial statements.

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Commitments and Contingent Liabilities

On April 27, 2022, the Company and Biostage executed a settlement with the plaintiffs in the Biostage Litigation (as defined below) which resolved all claims relating to the litigation as described in Note 13 – Litigation Settlement.

The Company is involved in various other 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. 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, 2023.

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 is currently undergoing unclaimed property audits conducted in various states. Based on the current stage of the audits, the Company has not accrued any loss contingencies related to these audits as of June 30, 2023.

Allowance for Expected Credit Losses on Receivables

The allowance for expected credit losses on receivables is used to present accounts receivable, net at an amount that represents the Company’s estimate of the related transaction price recognized as revenue. The allowance represents an estimate of expected credit losses over the lifetime of the receivables, even if the loss is considered remote, and reflects expected recoveries of amounts previously written-off. The Company estimates the allowance on the basis of specifically identified receivables that are evaluated individually for impairment and an analysis of the remaining receivables determined by reference to past default experience. The Company considers the need to adjust historical information to reflect the extent to which current conditions and reasonable forecasts are expected to differ from the conditions that existed for the historical period considered. Losses on receivables have not historically been significant.

Management judgments are used to determine when to charge off uncollectible trade accounts receivable. The Company bases these judgments on the age of the receivable, credit quality of the customer, current economic conditions, and other factors that may affect a customer’s ability and intent to pay. Customers are generally not required to provide collateral for purchases.

Activity in the allowance for expected losses on receivables is as follows:

	Six Months Ended June 30,
(in thousands)	2023			2022
Balance, beginning of period	$	191		$	136
Provision for bad debts		18			107
Charge-offs and other		(55	)		(48	)
Balance, end of period	$	154		$	195

Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer.
