Subject: Annual Shareholder Meeting - Please vote!

To All Coherus Employees,

I am sending a reminder email to please vote for the proposals in our Proxy before the Annual Shareholder Meeting on May 27, 2026, at 1:30pm PST. There are several proposals in the Proxy for shareholders to vote on, including a proposal to reprice employee stock options which have strike prices that are $5 and above down to the closing price on the date of the meeting. The proposal requires that a majority of votes cast “FOR” to pass. We encourage you to vote your shares when you receive the proxy. For anyone who has not received the proxy via email, you can call our Proxy Solicitor – Christopher Rice at (203) 561-6945, and he can take your vote over the phone.

Thank you, Rebecca

Rebecca Sunshine
