#### WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?
The Record Date for the Annual Meeting is April 7, 2025. You are entitled to vote at the Annual Meeting only if you were a Class A stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. A list of stockholders entitled to vote at the Annual Meeting will be available at 25 Hartwell Avenue, Lexington, Massachusetts 02421 for 10 days before the Annual Meeting, and during the Annual Meeting, such list will be available to registered stockholders as a link on the Annual Meeting platform.

You will need to obtain your own Internet access if you choose to attend the Annual Meeting and/or vote online. Each share of our Class A common stock entitles its holder to one vote on all matters presented to our stockholders at the Annual Meeting. The holders of our Class B common stock are not entitled to vote on any matter before the Annual Meeting. If the holders of our Class B common stock convert their shares to Class A common stock after the Record Date, such Class A common stock will not be entitled to vote at the Annual Meeting. At the close of business on the Record Date, there were 39,328,820 shares of Class A common stock issued and outstanding and entitled to vote at the Annual Meeting.
