**Item 7.01 Regulation FD Disclosure**

On March 6, 2026, the Company issued a press release announcing its intention to effect a reverse stock split. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information contained in Item 7.01 of this Form 8-K (including Exhibit 99.1 attached hereto) shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly provided by specific reference in such a filing.

**Item 8.01 Other Events.**

Following stockholder approval of the Reverse Stock Split Proposal, the Board approved a final reverse stock split ratio of 1-for-10. Following such approval, the Company filed an amendment to its Charter (the "Charter Amendment") with the Secretary of State of the State of Delaware to effect the reverse stock split, with an effective time of 4:30 p.m. Eastern Time on March 13, 2026 ("Effective Time"). Beginning on March 16, 2026, the Common Stock is expected to continue to trade on The Nasdaq Global Market on a split-adjusted basis under the symbol "HBIO" with a new CUSIP number, 416906204.

At the Effective Time, every 10 shares of Common Stock outstanding will be combined, automatically and without any action on the part of the Company or its stockholders, into one share of Common Stock. No fractional shares will be issued in connection with the reverse stock split. Instead, the Company's transfer agent will aggregate all fractional shares and sell them as soon as practicable after the Effective Time at the then-prevailing prices on the open market, on behalf of those stockholders who would otherwise be entitled to receive a fractional share as a result of the reverse stock split. After that sale, each stockholder who would have been entitled to a fractional share will instead receive a cash payment (without interest) in an amount equal to its respective pro rata share of the total proceeds of such sale.

The reverse stock split will reduce the number of shares of Common Stock issued and outstanding from approximately 44,179,894 to approximately 4,471,989. Following the reverse stock split, the authorized number of shares of Common Stock will remain at 80,000,000.

The foregoing description of the Charter Amendment is qualified in its entirety by reference to the full text of the Charter Amendment, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

## Exhibit 3.1

**Exhibit 3.1**

**CERTIFICATE OF AMENDMENT OF THE SECOND AMENDED AND RESTATED** 

**CERTIFICATE OF INCORPORATION OF HARVARD BIOSCIENCE, INC.**

Pursuant to Section 242 of the General Corporation Law of the State of Delaware, Harvard Bioscience, Inc., a corporation organized and existing under the laws of the State of Delaware (the "Corporation"), does hereby certify as follows:

&nbsp;&nbsp;&nbsp;&nbsp;1. The name of the Corporation is Harvard Bioscience, Inc.

&nbsp;&nbsp;&nbsp;&nbsp;2. The Certificate of Incorporation of the Corporation was filed with the Secretary of State of the State of Delaware on September 8,
2000, and thereafter, Restated Certificates were filed on November 28, 2000 and December 12, 2000 with the Secretary of State of the State
of Delaware.

&nbsp;&nbsp;&nbsp;&nbsp;3. The Corporation's Second Amended and Restated Certificate of Incorporation is hereby further amended by adding the following
paragraph as the second paragraph of Article IV:

"Upon effectiveness of this Certificate of Amendment (the "Effective Time"), the shares of Common Stock issued and outstanding immediately prior to the Effective Time and the shares of Common Stock issued and held in the treasury of the Corporation immediately prior to the Effective Time are reclassified into a smaller number of shares such that each ten (10) shares of issued Common Stock immediately prior to the Effective Time is reclassified into one (1) share of Common Stock. Notwithstanding the immediately preceding sentence, no fractional shares shall be issued as a result of the reverse stock split. Instead, any stockholder who would otherwise be entitled to a fractional share of Common Stock as a result of the reclassification shall be entitled to receive a cash payment equal to the product of such resulting fractional interest in one share of Common Stock multiplied by the closing trading price of the Common Stock on the trading day immediately preceding the effective date of the reverse stock split. Notwithstanding the foregoing, the Corporation shall not be obliged to issue certificates evidencing the shares of Common Stock outstanding as a result of the reverse stock split or cash in lieu of fractional shares, if any, unless and until the certificates evidencing the shares held by a holder prior to the reverse stock split are either delivered to the Corporation or its transfer agent, or the holder notifies the Corporation or its transfer agent that such certificates have been lost, stolen or destroyed and executes an agreement satisfactory to the Corporation to indemnify the Corporation from any loss incurred by it in connection with such certificates."

&nbsp;&nbsp;&nbsp;&nbsp;4. The Amendment of the Second Amended and Restated Certificate of Incorporation herein certified has been duly adopted in accordance
with the provisions of Section 242 of the General Corporation Law of the State of Delaware.

&nbsp;&nbsp;&nbsp;&nbsp;5. This Certificate of Amendment shall be effective on March 13, 2026 at 4:30 p.m., Eastern Time.

**IN WITNESS WHEREOF**, this Corporation has caused this Certificate of Amendment of the Second Amended and Restated Certificate of Incorporation to be signed by its President and Chief Executive Officer this March 6, 2026.

## Exhibit 99.1

**Exhibit 99.1**

Harvard Bioscience Announces Reverse Stock Split

 

- *Harvard Bioscience's common stock is expected to begin trading on a post-split adjusted basis on March 16, 2026*

 

**HOLLISTON, Mass., March 6, 2026 (GLOBE NEWSWIRE) --** Harvard Bioscience, Inc. (Nasdaq: HBIO) (the "Company" or "Harvard Bioscience"), a global leader in life science research tools, today announced that its board of directors approved the Company's 1-for-10 reverse stock split (the "Reverse Split") of the Company's common stock, par value $0.01 per share. The Reverse Split was approved by the stockholders of the Company at a special meeting held on March 6, 2026.

The Reverse Split will legally take effect at 4:30 p.m. Eastern Time, on March 13, 2026. The Reverse Split is intended to increase the per share trading price of the Company's common stock to enable the Company to regain compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market.

The 1-for-10 Reverse Split will automatically convert every 10 current shares of the Company's common stock into one share of common stock. No fractional shares will be issued in connection with the Reverse Split. Stockholders who would otherwise hold a fractional share of the Company's common stock following the Reverse Split will receive a cash payment in lieu thereof at a price equal to that fractional share to which the stockholder would otherwise be entitled multiplied by the closing sale price of the common stock on The Nasdaq Capital Market, as adjusted for the Reverse Split, on March 13, 2026.

The Reverse Split will reduce the number of shares of outstanding common stock from approximately 44,719,894 shares, to approximately 4,471,989 shares. The total authorized number of shares will not be reduced. Proportional adjustments will also be made to the exercise and conversion prices of the Company's outstanding stock options, warrants, and convertible securities, and to the number of shares issued and issuable under the Company's stock incentive plans.

Stockholders holding their shares electronically in book-entry form are not required to take any action to receive post-split shares. Stockholders owning shares through a bank, broker, or other nominee will have their positions automatically adjusted to reflect the Reverse Split, subject to brokers' particular processes, and will not be required to take any action in connection with the Reverse Split. For those stockholders holding physical stock certificates, the Company's transfer agent, Computershare Inc., will send instructions for exchanging those certificates for shares held electronically in book-entry form or for new certificates, in either case representing the post-split number of shares, and any payments in cash in lieu of fractional shares, if applicable.

Additional information regarding the Reverse Stock Split is available in the Company's definitive proxy statement originally filed with the U.S. Securities and Exchange Commission (SEC) on January 30, 2026.
