HARVARD BIOSCIENCE INC Commitments Disclosure

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 flow. 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 January 2026, the Company received notification from a third-party alleging a potential claim for breach of contract. The Company does not concede the validity of any allegations and is vigorously defending the matter. While the outcome is uncertain, it is reasonably possible a loss could be incurred. Management estimates the range of potential loss to be between $0.1 million and $0.8 million. The Company does not expect that this matter will have a material adverse impact on its financial position.

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 December 31, 2025 and 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 an expense of $0.3 million during the year ended December 31, 2024, related to the completion of unclaimed property audits which have been included in other operating expenses in the consolidated statement of operations.
