Mr. Kelly previously has served as the Company’s Chief Financial Officer since May 2021. Mr. Kelly and the Company mutually agreed to Mr. Kelly’s promotion from the role of Chief Financial Officer to Chief Operating Officer, and this transition was not the result of any disagreement with the Company or its Board relating to the Company’s operations, policies or practices or any issues regarding its accounting policies or practices.
In connection with Mr. Kelly’s appointment as Chief Operating Officer of the Company, the Compensation Committee of the Board approved an increase to Mr. Kelly’s annual base salary to $510,000 with a target annual bonus equal to 45% of his annual base salary, effective as of the Effective Date.

In connection with Mr. Kelly’s promotion to Chief Operating Officer, the Board appointed Naresh Tanna, age 45, as Chief Financial Officer of the Company. As Chief Financial Officer, Mr. Tanna will serve as the Company’s principal financial officer.
As Chief Financial Officer, Mr. Tanna will oversee the Company’s financial planning and reporting, investor relations, and corporate communications functions, building on his prior leadership as Vice President of Investor Relations and Chief of Staff to the Chief Executive Officer, positions he held since joining the Company in January 2022 and where he oversaw investor relations, strategic projects, commercial strategy, and business intelligence. Mr. Tanna has been an integral member of the Senior Leadership Team helping to drive the Company’s corporate strategy into fruition as it advances its wholly owned in vivo gene editing programs.
Mr. Tanna served as a Global Oncology Marketing Director at Amgen Inc. from January 2020 until joining the Company in January 2022.

Mr. Tanna holds a Master of Business Administration from the IESE Business School and a Bachelor of Science in Biomedical Engineering and Political Science from Rutgers School of Engineering and has earned a Chief Financial Officer certificate from the executive program at The Wharton School of the University of Pennsylvania.
In connection with Mr. Tanna’s appointment as Chief Financial Officer of the Company, the Company will enter into an employment agreement with Mr. Tanna. Under Mr. Tanna’s employment agreement, Mr. Tanna will receive an annual base salary equal to $400,000 with a target annual bonus equal to 40% of his annual base salary (pro-rated for 2026 based on the partial year served).
There are no arrangements or understandings between Mr. Tanna and any other person pursuant to which he was appointed as Chief Financial Officer of the Company.
The foregoing description of Mr. Tanna’s employment agreement is qualified in its entirety by reference to the full text of such agreement, which will be filed with the Company’s Quarterly Report on Form 10-Q for the quarter ending September 30, 2026.

Ms. Burris currently serves as the Company’s Vice President of Finance, a position she has held since November 2024. Ms. Burris first joined the Company in February 2019, and since that time, has held roles of increasing responsibility with the Company including Senior Director of Finance and Corporate Controller, Director of Investor Relations and Finance, and Director of Financial Reporting. As Vice President of Finance and Chief Accounting Officer, Ms. Burris is responsible for the Company’s accounting function, including technical accounting, accounting policy, internal controls over financial reporting, and external financial reporting.
