Harvard Bioscience Announces Strategic Consolidation of Manufacturing Operations to Improve Efficiency and Support Long-Term Growth

Streamlining production footprint and improving manufacturing efficiency through phased closure of Holliston, MA plant

Initiative expected to deliver approximately $3 million in cost savings in 2027 and $4 million in annual cost savings beginning in 2028 while improving throughput and execution

HOLLISTON, Mass., January 29, 2026 (GLOBE NEWSWIRE) -- Harvard Bioscience, Inc. (Nasdaq: HBIO) (the “Company” or “Harvard Bioscience”), today announced a strategic consolidation of its manufacturing operations designed to enhance operational efficiency, strengthen execution, and accelerate cost-savings efforts.

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.

“Building upon the enhanced flexibility provided by our recent refinancing, this consolidation represents a meaningful step forward in simplifying our manufacturing footprint and strengthening our operating model,” said John Duke, CEO of Harvard Bioscience. “As we have been able to take a deeper look at the business, concentrating our U.S. manufacturing and relocating certain operations to respective international facilities will better leverage the scale, capabilities, and expertise of our sites. We expect the operational synergies generated by the move to improve execution and increase speed-to-market as we build a more agile organization to drive long-term value creation for customers and shareholders.”

The Holliston facility will remain operational throughout 2026 to support continuity and customer service. The consolidation is expected to be completed by the first quarter of 2027. The Company has implemented a comprehensive, phased transition plan designed to prevent any disruption to order fulfillment, product quality, and technical support. Transition-related costs are expected to generate incremental operating expenses throughout 2026 and in the first half of 2027.

This initiative is expected to result in approximately $3 million in cost savings in 2027, and once fully implemented, approximately $4 million in annual cost savings going forward. The savings include reduced overhead, SKU rationalization, improved asset utilization, and a targeted reconfiguration of the Company’s workforce across impacted operations.

The Company has also filed a Current Report on Form 8-K with the U.S. Securities and Exchange Commission containing additional details regarding the consolidation of operations.
