Departure of Chief Financial Officer
On October 7, 2025, Vineet Agarwal announced his intention to resign from his position of Chief Financial Officer of Korro Bio, Inc., or Korro, effective October 17, 2025 to pursue another opportunity. In order to ensure the smooth transition of his functions, Mr. Agarwal has agreed to be available to serve as an advisor for 30 days thereafter. The board of directors of Korro, or the Board, and Korro are incredibly thankful to Mr. Agarwal for his long-standing service at Korro.
In recognition of Mr. Agarwal’s agreement to be available to advise Korro through a transition period, Mr. Agarwal’s employment with Korro will be treated as an ending pursuant to Section 3(d) of Mr. Agarwal’s employment agreement dated November 8, 2023, or the Employment Agreement. Accordingly, in connection with his resignation, Korro and Mr. Agarwal entered into a Separation Agreement, or the Separation Agreement, effective October 7, 2025, providing for separation benefits outside of the change in control period as described in the summary of the Employment Agreement included in Korro’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission, or SEC, on April 29, 2024, which description is incorporated herein by reference. In addition, Korro agreed to extend the post-termination exercise period for any vested stock options as of October 17, 2025 through March 31, 2027. Mr. Agarwal’s departure is not related to any disagreement between the parties as to the management of Korro or as to any matter relating to its operations, policies or practices.
The foregoing description of the Separation Agreement does not purport to be a complete description of the rights and obligations of the parties thereunder and is qualified in its entirety by reference to the full text of the Separation Agreement, a copy of which is filed as exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.
Appointment of Interim Chief Financial Officer and Principal Financial Officer
In light of Mr. Agarwal’s resignation, the Board appointed Dr. Ram Aiyar, President and Chief Executive Officer (principal executive officer), to serve as Korro’s interim Chief Financial Officer and principal financial officer, in addition to his current duties effective from October 17, 2025.
Biographical information for Dr. Aiyar is set forth in Korro’s definitive proxy statement on Schedule 14A filed with the SEC on April 29, 2025 and is incorporated herein by reference. Dr. Aiyar will not receive any additional compensation in connection with this interim appointment.
There is no arrangement or understanding between Dr. Aiyar and any other persons, respectively, pursuant to which he was selected as an officer. There are no family relationships among any of Korro’s directors or executive officers and Dr. Aiyar, and Dr. Aiyar does not have any direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K.
