5. -- France's Sanofi (SNY - Get Report) on Thursday went public with a campaign to buy Medivation (MDVN) , disclosing that a $9.3 billion cash offer for the San Francisco developer of cancer medicines had fallen on deaf ears.
Sanofi described its proposal, pitched at $52.50 a share, as nonbinding, and published a letter from CEO Olivier Brandicourt to Medivation President and CEO David T. Hung urging a meeting. In the letter on Thursday, Brandicourt complained that the target had ignored an April 15 letter outlining the proposed terms of the Sanofi offer, having rebuffed the suitor in a phone call on April 3. The two sides held their first phone conversation on March 25, Sanofi's letter stated.
Medivation closed on Thursday at $52.05, making the Sanofi proposal less than a 1% premium to that price. However, Medivation shares were trading at $41.25 a month ago, and Sanofi said its proposal was 50% more than the two-month average share price before takeover rumors emerged.
