Exhibit 99.1
Harvard Bioscience Announces First Quarter 2026 Financial Results
| · | First Quarter 2026 Revenues of $20.8M and Gross Margin of 59% |
| · | Consolidation of Manufacturing Operations Progressing on Schedule |
| · | Reaffirms Full Year 2026 Financial Guidance |
HOLLISTON, Mass., May 12, 2026 (GLOBE NEWSWIRE) -- Harvard Bioscience, Inc. (Nasdaq: HBIO) (the “Company” or “Harvard Bioscience”) today announced financial results for the first quarter ended March 31, 2026.
“First quarter revenues were in line with our expectations and gross margin expanded year-over-year, while we remained profitable on an adjusted EBITDA basis,” said John Duke, President and Chief Executive Officer. “We are encouraged by the adoption rates of our NPI portfolio – specifically the MeshMEATM organoid platform, and our BTX® Electroporation and SoHo™ Telemetry systems – which are deepening our reach into the biopharma sector. This shift toward a higher-margin product mix is expected to put us on a path toward consistent 60+% margin and higher recurring revenue. Additionally, our manufacturing consolidation is on track and is expected to yield significant efficiencies and cost savings. Looking ahead, we continue to focus on operational efficiency and believe we remain well positioned for our next phase of growth. We’re reaffirming our full year guidance, which anticipates high margin NPI sales growth driving bottom line growth in the second half of the year.”
First Quarter 2026 Results
For the first quarter of 2026, the Company reported revenues of $20.8 million compared to $21.8 million in the first quarter of 2025. Gross margin for the first quarter of 2026 was 59%, compared to 56% in the first quarter of 2025.
Net loss for the first quarter of 2026 was $(3.4) million, compared to a net loss of $(50.3) million in the first quarter of 2025, which included goodwill impairment of $(48.0) million. Adjusted EBITDA for the first quarter of 2026 was $0.8 million compared to $0.8 million in the first quarter of the prior year. Cash (used) in and provided by operations was $(0.7) million during the three months ended March 31, 2026, compared to $3.0 million in the same period in 2025. The reduction in the cash balance is primarily due to one-time charges related to the process that resulted in the debt refinancing.
This press release includes certain financial information presented on an adjusted, or non-GAAP, basis. For additional information on the non-GAAP financial measures included in this press release, see “Use of Non-GAAP Financial Information” and “Reconciliation of GAAP to Non-GAAP Financial Measures” below.
Second Quarter 2026 Guidance
The Company’s Q2 outlook reflects year-over-year revenue growth in the mid-single digit range at the midpoint of guidance, margin expansion as NPI adoption scales, and continued profitability on an adjusted EBITDA basis. We expect:
| · | Revenue between $20.5 million and $22.5 million |
| · | Adjusted gross margin between 57% and 59% |
| · | Adjusted EBITDA between $1.0 and $2.0 million |
Full Year 2026 Guidance
The Company is reaffirming its full-year guidance and anticipates a ramp in revenue in the second half of the year, driven by expected sales growth in our higher margin NPI pipeline, which includes products for organoids and electroporation. The Company continues to expect:
| · | Revenue growth between 2% and 4% |
| · | Adjusted gross margin between 58% and 60% |
| · | Adjusted EBITDA growth between 6% and 10% |
