July 1 French drugmaker Sanofi SA will
raise its stake in Regeneron Pharmaceuticals Inc to
22.5 percent, Sanofi said in a U.S. regulatory filing Tuesday,
as part of an agreement between the companies allowing Sanofi to
buy up to 30 percent.
Regeneron shares gained 4 percent, or $11.45, to $294.01 in
The two companies have several drug development
partnerships, including potential multi-billion dollar
cholesterol drugs, and Sanofi had a 20.5 percent stake in
Regeneron as of April 7.
Sanofi Chief Executive Officer Chris Viehbacher said last
year when the company had a 16 percent stake in Regeneron that
it could raise the stake as high as 30 percent. In January,
Regeneron said it had an investor agreement with Sanofi allowing
it to take a 30 percent stake and to name a board member. It
appointed Robert Ingram to Regeneron's board earlier this year.
The French company has been under pressure to put cash on
hand to work since it became clear that it would not need the
money to buy back a stake holding from L'Oreal.
