Item 2.05 Costs Associated with Exit or Disposal Activities.

On January 23, 2026, the Board of Directors of Harvard Bioscience, Inc. (the “Company”) approved management’s comprehensive plan, referred to as Project Viking, for the strategic consolidation of its manufacturing operations to improve efficiency and support long-term growth.

The Company will close its manufacturing facility in Holliston, MA and transition U.S. production to its manufacturing hub in Minneapolis, MN. Certain operations will also be relocated to facilities in Germany, Sweden, and the UK, aligning specific product lines with their designated center of excellence and most strategically advantageous logistical location. The Company expects the initiative to deliver approximately $3 million in cost savings in 2027, and approximately $4 million in annual cost savings beginning in 2028, while improving throughput and execution. The savings include reduced overhead, SKU rationalization, improved asset utilization, and targeted reconfiguration of the Company’s workforce across impacted operations.

The Company expects to incur pre-tax restructuring charges related to Project Viking in the range of approximately $3.4 to $4.4 million, including non-cash asset write-off and/or accelerated depreciation charges in the range of approximately $0.6 to $0.7 million, primarily related to the exit of production activities and manufacturing operations at the Holliston, MA manufacturing site. These amounts are estimates and are subject to future changes.

We may incur additional charges in connection with Project Viking and will provide an estimate of any additional charges when known. Restructuring actions under the program are expected to be substantially complete by the first half of 2027. Future actions by the Company or changes in circumstances from current assumptions may cause actual results and future cash payments to differ.

Item 7.01. Regulation FD Disclosure.

On January 29, 2026, the Company issued a press release relating to Project Viking. A copy of the press release is attached hereto as Exhibit 99.1.

The information in Item 7.01 of this Form 8-K, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such a filing.
