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. Third Quarter 2026 Guidance The Company’s third quarter outlook reflects expected mid-single-digit year-over-year revenue growth at the midpoint of guidance, driven by expected ongoing demand across CMT and new product innovation (NPI) platforms and improving year-over-year profitability on an adjusted EBITDA basis.

The Company now expects: · Revenue growth between 3% and 5% · Adjusted gross margin between 57% and 59% · Adjusted EBITDA growth between 6% and 10% Webcast and Conference Call Details In conjunction with this announcement, Harvard Bioscience will be hosting a conference call and webcast today at 8:00 a.m. Eastern Time.

Use of Non-GAAP Financial Information In this press release we have included non-GAAP financial information, including one or more of adjusted operating income (loss), adjusted operating margin, adjusted gross margin, adjusted net income (loss), adjusted EBITDA, adjusted EBITDA margin, diluted adjusted earnings (loss) per share, net debt, adjusted gross profit, and non-GAAP revenue on a constant currency basis. We believe that this non-GAAP financial information provides investors with an enhanced understanding of the underlying operations of our business. For the periods presented, these non-GAAP financial measures have excluded certain expenses and income resulting from items that we do not believe are reflective of the underlying operations of the business. Items excluded include stock-based compensation, amortization of intangibles related to acquisitions, restructuring charges, other operating expenses, goodwill impairment, interest and other expense, net, income taxes, and the tax impact of reconciling items. Management believes that this non-GAAP financial information is important in comparing current results with prior period results and is useful to investors and financial analysts in assessing the Company’s operating performance. Historical non-GAAP financial information included herein is accompanied by a reconciliation to the nearest corresponding GAAP measure, which is included below. In addition, the forward-looking Adjusted gross margin and Adjusted EBITDA guidance for the third quarter of 2026 and full-year 2026 excludes potential charges or gains that may be recorded during the fiscal year, including among other things, restructuring and reorganization expenses, and non-GAAP restructuring related expenses. The Company has not attempted to provide reconciliations of such forward-looking non-GAAP earnings guidance to the comparable GAAP measure, as permitted by Item 10(e)(1)(i)(B) of Regulation S-K, because the impact and timing of these potential charges or gains is inherently uncertain and difficult to predict and is unavailable without unreasonable efforts. In addition, the Company believes such reconciliations would imply a degree of precision and certainty that could be misleading to investors. Such items could have a substantial impact on GAAP measures of the Company’s financial performance. The non-GAAP financial information provided in this press release should be considered in addition to, not as a substitute for, the financial information provided and presented in accordance with GAAP and may be different from other companies’ non-GAAP financial information.
