Amendment Description Harvard Bioscience, Inc. (the “Company”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2020 (the “Original Filing”) with the Securities and Exchange Commission on March 12, 2021. Due to a technical filing error, certain paragraphs in “Item 1. Business” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Original Filing were inadvertently omitted from the as-filed version of the Original Filing. The Company is filing this Amendment No. 1 to its Annual Report on Form 10-K/A (this “Amendment No. 1”) solely to insert such paragraphs and to add a conformed signature to the Consent of Grant Thornton LLP, the Company’s independent registered public accounting firm, which was inadvertently omitted from the Original Filing. Further, as required by Rule 12b-15 promulgated under the Securities Exchange Act of 1934, as amended, new certifications pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 by the Company’s principal executive officer and principal financial officer are filed herewith as exhibits to this Amendment No. 1. Accordingly, Item 15 of Part IV of the Original 10-K has been amended and restated in its entirety to include the certifications as exhibits.   Except as described above, this Amendment No. 1 speaks as of the original filing date of the Original Filing and does not amend or update any other information contained in the Original Filing to reflect events that may have occurred subsequent to the original filing date. The Company has included a complete copy of the Original Filing, as amended per above, in this filing.
