Exhibit 99.2

Dear Team,

As you may have seen, today Sanofi issued a press release requesting that the Medivation Board of Directors set a record date regarding its proposed consent solicitation – through which it is seeking stockholder approval to replace all the members of our Board of Directors. In accordance with this request, our Board of Directors set the record date for today, June 1, 2016. Our press release announcing the record date can be found here: http://investors.medivation.com/releasedetail.cfm?ReleaseID=973881

Today’s request from Sanofi is a simple procedural matter that determines which stockholders will be eligible to participate in the proposed consent solicitation. To be clear, Sanofi’s consent solicitation statement still needs to receive clearance from the SEC before stockholders can take any action.

While this development is straightforward and one we expected, it may still generate interest from members of the media. In any case, it should continue to be business as usual for all of us at Medivation. Let’s stay laser-focused on executing our strategy.

We will continue keep you informed of significant developments and appreciate your continued dedication to Medivation and our patients.

Sincerely,

David & Marion
