&nbsp;&nbsp;&nbsp;&nbsp;· *Third Quarter 2025 Guidance Reflects Improved Operations and Strong Financial Discipline* 

&nbsp;&nbsp;&nbsp;&nbsp;· *New Credit Amendment Signed, Extending Refinance Deadline to December 5th* 

HOLLISTON, Mass., August 11, 2025 (GLOBE NEWSWIRE) -- Harvard Bioscience, Inc. (Nasdaq: HBIO) (the "Company") today announced financial results for the second quarter and six months ended June 30, 2025.

"We made solid progress in the second quarter exceeding our revenue guidance. In my short time as CEO, I have already seen first-hand the dedication of our team. The fundamentals of the business remain intact with attractive margins and promising technologies serving high-growth markets," said John Duke, President and CEO. "Our priorities are to grow our core business and re-structure our balance sheet. We are taking immediate actions on both fronts and expect these actions to position us well for revenue growth and margin expansion in 2026 and beyond."

**Second Quarter 2025 Results**

For the second quarter of 2025, the Company reported revenues of $20.5 million compared to $23.1 million in the second quarter of 2024. Gross margin for the second quarter of 2025 was 56.4%, compared to 57.2% in the second quarter of 2024.

Net loss for the second quarter of 2025 was ($2.3) million compared to a net loss of ($2.9) million in the second quarter of 2024, which included a loss on marketable securities of ($0.3) million. Adjusted EBITDA for the second quarter of 2025 was $1.5 million compared to $1.3 million in the second quarter of 2024. Cash provided by operations was $2.8 million during the three months ended June 30, 2025, compared to ($0.8) million in the same period in 2024.

#### Credit Agreement Update
The Company entered into an amendment to its credit agreement. Pursuant to the amendment, the lenders have agreed to waive the events of default due to the Company's failure to achieve prior refinancing milestones and failure to comply with certain financial covenants as of the June 30, 2025 test date. Additionally, the lenders agreed not to test the financial covenants for the fiscal quarter ended September 30, 2025, provided that the Company continues to comply with its payment obligations and minimum liquidity requirements included in the credit agreement.

In connection with the amendment, the Company also agreed to accomplish steps towards the refinancing or repayment of the credit agreement by no later than December 5, 2025.

#### Six Months Ended June 30, 2025 Results
For the six months ended June 30, 2025, the Company reported revenues of $42.2 million, compared to $47.6 million in the same period of the prior year. Gross margin for the six months ended June 30, 2025 was 56.2% compared with 58.8% in the same period of the prior year. Gross profit was $23.7 million for the first six months of 2025 compared to $28.0 million in the same period of the prior year.

Net loss for the six months ended June 30, 2025 was ($52.6) million compared to a net loss of ($7.6) million in the same period of the prior year, primarily due to goodwill impairment in the first quarter of 2025 of $48.0 million. Adjusted EBITDA for the six months ended June 30, 2025 was $2.3 million, compared to adjusted EBITDA of $2.8 million for the same period of the prior year. Cash provided by operations was $5.7 million during the six months ended June 30, 2025 compared to $0.6 million in the same period of the prior year.

#### Third Quarter 2025 Guidance
The Company expects third quarter 2025 revenues of $19 million to $21 million and gross margin in the 56% to 58% range.
