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

Resignation of Director

On January 7, 2026, Andrea Saia, a member of the Company’s Board of Directors (the “Board”), stepped down from the Board, effective January 9, 2026. Ms. Saia’s resignation is not the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Appointment of Director

On January 8, 2026, the Board appointed Karen Prange as a new member of the Board and as a member of the Compensation Committee of the Board, with such appointment effective January 9, 2026.

Ms. Prange fills the vacancy created by the resignation of Ms. Saia and her term of office as a class III director will expire at the Company’s 2026 annual meeting of stockholders or until her successor has been elected and qualified or her earlier death, resignation or removal. The Board has determined that Ms. Prange is an “independent director” as defined under the applicable rules and regulations of the Securities and Exchange Commission (“SEC”) and the listing requirements and rules of the Nasdaq stock market.

Ms. Prange has served on the board of directors of Atricure, Inc., a medical device company, since December 2019, and on the board of directors of Embecta Corp., a medical device and technology company, since April 2022. She also currently serves on the board of directors of WS Audiology, a privately held medical device company, and has served as a Senior Advisor at EQT Group, a global investment organization, since March 2020. In her most recent operating role, Ms. Prange was Executive Vice President and Chief Executive Officer for the Global Animal Health, Medical and Dental Surgical Group at Henry Schein, Inc., and a member of its Executive Committee, from May 2016 to April 2018. Prior to that, she was Senior Vice President of Boston Scientific and President of its Urology and Pelvic Health business from June 2012 to May 2016. Earlier in her career, Ms. Prange held various leadership positions at Johnson & Johnson, including sales, marketing, market development and general management roles. She also previously served on the boards of directors of several medical device companies: Nevro Corp. (acquired by Globus Medical, Inc.) from December 2019 to April 2025; ViewRay, Inc. from June 2021 to October 2023; and Cantel Medical Corporation (acquired by STERIS plc) from October 2019 to June 2021. Ms. Prange holds a B.S. from the University of Florida.

Except as described below with respect to Ms. Prange’s equity compensation arrangements, Ms. Prange will be compensated in a manner consistent with the Company’s compensation policy for other non-employee directors, as described under the heading “Non-Employee Director Compensation Policy” in the Company’s definitive proxy statement filed with the SEC on April 11, 2025 (the “Policy”). Pursuant to the Policy, as it was subsequently amended effective January 8, 2026, Ms. Prange will receive an initial equity grant of 18,667 restricted stock units (“RSUs”) under the Company’s 2020 Equity Incentive Plan (the “Plan”) in connection with her initial appointment to the Board, which RSUs will vest quarterly over a three-year period. In addition, Ms. Prange will receive an annual grant of 10,667 RSUs under the Plan on the date of the Company’s Annual Meeting of Stockholders, which RSUs will vest upon the earlier of (i) the one-year anniversary of the date of grant or (ii) the date of the Company’s next Annual Meeting of Stockholders. Ms. Prange will also enter into the Company’s standard director and officer indemnification agreement, the form of which was previously filed by the Company as Exhibit 10.1 to Amendment No. 1 to the Company’s Registration Statement on Form S-1/A (Registration No. 333-248225), filed with the SEC on September 9, 2020. There are no arrangements or understandings between Ms. Prange and any other persons pursuant to which she was appointed as a director. Furthermore, there are no transactions in which Ms. Prange has an interest that would be required to be reported under Item 404(a) of Regulation S-K.

All statements other than statements of historical fact are forward-looking statements. Forward-looking statements are based on management’s current assumptions and expectations of future events and trends, which affect or may affect the Company’s business, strategy, operations or financial performance, and actual results and other events may differ materially from those expressed or implied in such statements due to numerous risks and uncertainties.

Factors that could cause actual results or other events to differ materially from those contemplated in this press release can be found in the Risk Factors section of the Company’s public filings with the Securities and Exchange Commission, including its latest annual and quarterly reports.
