Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 4, 2025, Harvard Bioscience, Inc. (the “Company”) received written notice (the “Notification Letter”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it is not in compliance with the minimum bid price requirement for continued listing on The Nasdaq Global Market under Nasdaq Listing Rule 5450(a)(1). Nasdaq Listing Rule 5450(a)(1) requires listed securities to maintain a minimum bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of thirty (30) consecutive business days. Based on the closing bid price of the Company’s common stock for the thirty (30) consecutive business days from February 21, 2025 to April 3, 2025, the Company no longer meets the minimum bid price requirement.

The Notification Letter does not impact the Company’s listing on The Nasdaq Global Market at this time. The Notification Letter states that the Company has 180 calendar days, or until October 1, 2025, to regain compliance with Nasdaq Listing Rule 5450(a)(1). To regain compliance, the bid price of the Company’s common stock must have a closing bid price of at least $1.00 per share for a minimum of ten (10) consecutive business days. If the Company does not regain compliance with Nasdaq Listing Rule 5450(a)(1) by October 1, 2025, the Company may be eligible to transfer from the Nasdaq Global Market to the Nasdaq Capital Market and seek an additional 180 calendar day compliance period. To qualify, the Company would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the bid price requirement, and would need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. However, if it appears to the staff of Nasdaq (the “Staff”) that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq would notify the Company that its securities would be subject to delisting. In the event of such a notification, the Company may appeal the Staff’s determination to delist its securities, but there can be no assurance the Staff would grant the Company’s request for continued listing.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(b) Departure of Chief Financial Officer.

On April 7, 2025, Jennifer Cote notified the Company of her resignation as Chief Financial Officer and Treasurer.

Ms. Cote’s resignation is not a result of any disagreement with the Company or any matter relating to financial policies or procedures.

On April 10 2025, the Board of Directors of the Company appointed Mark Frost to serve as Interim Chief Financial Officer and Treasurer effective upon Ms. Cote’s resignation (the “Effective Date”).

Prior to Argon, Mr. Frost was Chief Financial Officer for three public Healthcare companies including Analogic, AngioDynamics and AMRI. Mr. Frost began his career with General Electric, where he held a variety of finance roles over the course of 14 years.

(e) Compensatory Arrangements

In connection with the appointment of Mr. Frost as the Company’s Interim Chief Financial Officer and Treasurer, the Company and Mr. Frost entered into a letter agreement (the “Letter Agreement”) dated April 10, 2025. The Letter Agreement provides that Mr. Frost will receive an annual base salary of $320,000. Mr. Frost will also be eligible to receive a cash bonus of $50,000 payable upon the Company’s repayment in full of the indebtedness due under the Company’s existing term loan and senior revolving credit facility, subject to Mr. Frost’s continued employment with the Company at the time of such repayment. On the Effective Date, Mr. Frost will also receive an award of 100,000 time-based restricted stock units (“RSUs”). The RSUs will vest in full one year from the Effective Date (the “Vesting Date”), subject to Mr. Frost’s continued employment with the Company. If Mr. Frost’s employment is terminated by the Company without cause or by Mr. Frost for any reason prior to the Vesting Date, a number of RSUs equal to the total number of RSUs multiplied by the number of full months elapsed from the Grant Date to the date of such termination of employment divided by 12 shall vest as of the date of termination.

The foregoing description of the Letter Agreement is qualified in its entirety by reference to the complete text of the Letter Agreement, which is attached hereto as Exhibit 10.1 and incorporated by reference herein.
