Additional 402(v) Disclosure | Reflects the cumulative total shareholder return at the end of the identified year, assuming $100 was invested after the market closed on December 31, 2019 in our common stock and in the Nasdaq Biotechnology Index, and assuming reinvestment of dividends, if any. Analysis of the Information Presented in the Pay Versus Performance Table We describe the relationships between CAP and our cumulative TSR and net loss below. We also compare our cumulative TSR with the Nasdaq Biotechnology Index, our peer index. We currently do not use financial performance measures, including our cumulative TSR, our net loss, or the cumulative TSR of our peer index in our compensation program or for comparison to any corporate goals. Instead, as a clinical stage gene editing company, our compensation program is designed primarily to advance our clinical programs and further our product development pipeline, thereby driving long-term stockholder value. For example, our 2023 annual performance-based cash bonus program included goals relating to the advancement of reni-cel, the development of our in vivo drug discovery pipeline, and value creation through business development. Similarly, our equity award program includes annual PSU grants to our executive officers that are earned only upon the achievement of pre-established performance goals, which historically have included research and development milestones such as establishing proof-of-concept and the clearance of investigational new drug applications, and completion of business development transactions that must be satisfied within a specified time period. See “Compensation Discussion and Analysis” for a detailed description of our compensation program. We believe that using these non-financial performance metrics best incentivizes our executive management and strengthens our alignment with our pay for performance compensation philosophy, while focusing on our long-term sustainable growth. Changes in PEO and NEOs Our chief executive officers and NEOs have changed over the periods reflected in the Pay Versus Performance Table, making year-to-year comparisons of CAP difficult. Most significant are the changes in chief executive officers. Ms. Collins served as our chief executive officer for all of 2020 and into February 2021. In connection with Ms. Collins’ separation from the company in February 2021, she forfeited certain equity awards held by her with a fair value as of December 31, 2020 of approximately $13.4 million, resulting in reduced CAP to her in 2021 and reduced aggregate CAP to PEOs in 2021 for purposes of the below charts. Mr. Mullen served as our chief executive officer from February 2021 until June 2022, at which time he transitioned to executive chair of our Board and Dr. O’Neill became our chief executive officer. We have similarly experienced changes in our other NEOs over the applicable periods, as we conducted a strategic reprioritization in early 2023 to focus on hemoglobinopathies and in vivo gene editing. In connection with the appointments of new NEOs over the periods, we enter into offer letters pursuant to which we grant the new officers certain new hire equity awards that can impact the ability to compare CAP year-to-year. Components of Compensation Actually Paid that Vary with Performance The components of CAP that vary with performance each year are: our annual incentive payouts, the fair value of long-term incentive awards granted in each year and the change in fair value of equity awards during the year. The decisions regarding our annual incentive payouts and our long-term incentive awards are described in our proxy statements for the applicable year, including this Proxy Statement. The addition of the change in fair value of equity awards during the year is the most significant performance-related difference between CAP and the totals reported in the Summary Compensation Table. The change in fair value of equity awards during the year varies with our annual share price appreciation and performance against our PSU goals. Pay versus Performance: Graphical Descriptions The illustrations below provide a graphical description of CAP (as calculated in accordance with the SEC rules) and the following measures: •Editas’ cumulative TSR and our Peer Group’s TSR; and •Editas’ net loss. For purposes of reflecting CAP in these charts, we have aggregated the compensation of the PEOs in each year where there was more than one PEO for such year. |  |  |  |  |  |
