Harvard Bioscience Announces Preliminary Fourth Quarter Financial Results, Positive Outlook for 2026 & Outlines Long-Term Strategic Focus Areas

 

- *Reports preliminary fourth quarter revenue in line with guidance, gross margin at high end of guidance, and strong year over year adjusted EBITDA performance* 

- *Expects year over year revenue growth and mid-to high-single-digit EBITDA growth in 2026*

- *Outlines strategy focused on positioning the company as a leader in the growing translational science tools market while expanding consumables revenue and improving operational performance*

 

**HOLLISTON, Mass., February 10, 2026 (GLOBE NEWSWIRE) --** Harvard Bioscience, Inc. (Nasdaq: HBIO) (the "Company" or "Harvard Bioscience"), a global leader in life science research tools, today announced preliminary financial results for the fourth quarter ended December 31, 2025. In conjunction with these results, the Company outlined a cohesive long-term strategy designed to leverage its market-leading portfolio to drive sustainable growth and increase shareholder value.

**Preliminary Fourth Quarter 2025 Financial Highlights**

Based on preliminary unaudited information, the Company expects to report:

• **Revenue** of $23.7 million, above the midpoint of the $22.5 million to $24.5 million guidance range.

• **Gross Margin** of 60%, at the high end of the 58% to 60% guidance range, driven by an improved mix to higher
margin product lines, as well as the benefit of prior cost reductions.

• **Adjusted EBITDA** of $3.8 million, which reflects 27% growth year over year, driven by cost reduction, improved expense management
 and solid execution.

**A Strategy for Growth: Bridging the Gap to Human Health**

As the life sciences industry accelerates toward New Approach Methodologies (NAMs), Harvard Bioscience is evolving from a traditional tools provider into a leading enabler of Translational Science – uniquely positioned to bridge the gap between laboratory research and human clinical success. Building on its gold-standard preclinical foundation, the Company plans to align its portfolio, innovation pipeline, and operating model around four strategic pillars:

• **Leading the Translational Bridge:** bridging in vivo and in vitro research by leveraging the Company's
 strong preclinical position to facilitate the industry's transition into the organoid and 3D biology markets, improving the
 translational relevance of early-stage research, and offering customers an integrated solution across critical stages of discovery
 and development.

• **New Product Introduction (NPI) Pipeline:** modernizing preclinical and translational workflows through differentiated and
 innovative high-margin platforms such as SoHo™ telemetry, and proprietary MeshMEA and Incub8 platforms, both of which are designed
 for organoid and tissue recording.

• **Consumables Revenue Expansion:** focusing resources and investments on higher-margin consumables and software with a clear
 path to increasing mix of recurring revenue from 55% of total revenues currently.

• **Operational Excellence and Disciplined Growth:** driving operational excellence and disciplined growth across our global
 footprint by strengthening our leadership position in the preclinical business. This foundation provides the capital necessary to
 fuel R&D and strategic bolt-on acquisitions. The Company will also focus on driving consistent profitability by maintaining cost
 discipline and operational efficiency, supported by its recently announced U.S. manufacturing consolidation and the stronger balance

**Management Commentary**

"We're pleased with our fourth quarter performance and excited to share an overview of our go-forward strategy," said John Duke, Chief Executive Officer. "With a stronger foundation provided by our refinancing and strategic consolidation, we're scaling our business model by focusing our priorities on the evolving needs of the life sciences industry. We are excited for what's ahead and are confident we will drive year over year revenue growth and mid-to high-single digit adjusted EBITDA growth in 2026."

**CEO Letter to Shareholders**

The Company has published a Letter to Shareholders from Chief Executive Officer, John Duke, which provides additional context on the long-term strategy. The letter can be accessed on the Investor Relations website at https://investor.harvardbioscience.com/.
