HOLLISTON, Mass., March 12, 2026 (GLOBE NEWSWIRE) -- Harvard Bioscience,
Inc. (Nasdaq: HBIO) (the “Company” or “Harvard Bioscience”) today announced financial results for the fourth quarter
and full year ended December 31, 2025.
“2025 was a pivotal year for Harvard Bioscience as we
strengthened our balance sheet and streamlined our operating model. This culminated in fourth quarter results that reflect disciplined
execution, an improved product mix, and the cost reductions implemented throughout the year,” said John Duke, President and Chief
Executive Officer. “As we look ahead, we are evolving from a traditional life science tools provider into a leading enabler of translational
science. By embracing the ongoing shift to New Approach Methodologies (NAMs) and focusing on new products for translational science, we’ll
help our customers generate more predictive, human-relevant data earlier in the drug development process. We believe we are well-positioned
for a new phase of growth and are confident in our outlook and our ability to drive sustainable shareholder value in 2026 and beyond.”
“I’m pleased to have been appointed on a permanent
basis and to continue working with the Harvard Bioscience team,” said Mark Frost, Chief Financial Officer. “We’ve made
significant progress over the past year. I’m excited by the opportunity ahead, and I look forward to further engagement with our
team, customers, and shareholders.”
Fourth Quarter 2025 Results
For the fourth quarter of fiscal 2025, the Company reported revenues of
$23.7 million compared to $24.6 million in the fourth quarter of fiscal 2024. Gross margin for the three months ended December 31, 2025
was 59.7%, compared to 57.1% in 2024. The year-over-year increase was mostly due to the impact of cost containment actions and favorable
product mix.
Net (loss) income for the fourth quarter of 2025 was ($2.8) million compared
to $18 thousand in the fourth quarter of 2024. Adjusted EBITDA for the fourth quarter of 2025 was $3.8 million compared to $3.0 million
in the fourth quarter of the prior year. Cash (used in) provided by operations was ($0.1) million during the three months ended December
31, 2025, compared to $1.7 million in the same period in 2024.
Results for Year Ended December 31, 2025
For the year ended December 31, 2025, revenues were $86.6 million compared
to $94.1 million for the year ended December 31, 2024. Revenues declined as a result of a challenging global market and reduced spending
by CROs, distributors and academic research institutions. Gross margin for the year ended December 31, 2025 was 57.7%, compared to gross
margin of 58.2% in the prior year. Gross margin was unfavorably impacted by the under-absorption of fixed manufacturing overhead costs,
which was partially offset by a better mix of lower labor costs and higher margin products.
Net loss for the year ended December 31, 2025 was ($56.7) million
compared to net loss of ($12.4) million for the year ended 2024, primarily due to goodwill impairment in the first quarter of 2025 of
$48.0 million. The Company’s net loss for 2025 included costs of ($1.8) million in connection with our debt refinancing and a loss
on pension settlement of ($1.2) million. Adjusted EBITDA for the year ended December 31, 2025 was $8.1 million, compared to adjusted EBITDA
of $7.2 million for the year ended 2024. Cash provided by operations was $6.7 million during the year ended December 31, 2025, compared
to $1.4 million in the year ended 2024.
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.
First Quarter 2026 Guidance
The Company expects:
| · | Revenue between $20.0 million and $22.0 million |
| · | Adjusted gross margin between 57% and 59% |
| · | Adjusted EBITDA between $1.0 million and $2.2 million. |
Note that the prior-year comparable first quarter period did
not include tariff impacts and was minimally affected by NIH funding headwinds.
Full Year 2026 Guidance
Guidance for the full year 2026 is expected to be driven by
higher margin New Product Innovation (NPI) revenue as the Company focuses on Translational Science. Growth
is expected to be supported by a stabilized NIH funding environment and a reduction in tariff disruptions. The Company expects:
| · | Revenue growth between 2% and 4% |
| · | Adjusted gross margin between 58% and 60% |
| · | Adjusted EBITDA growth between 6% and 10%. |
