Regeneron to expand in Westchester, add 400 jobs

Regeneron Pharmaceuticals Inc. expects to create more than 400 new jobs as part of an expansion of its Mount Pleasant corporate headquarters and laboratories, the company announced today.

The biopharmaceutical research and development company, headquartered in Tarrytown, will add two buildings with 300,000 square feet of laboratory and office space to its complex at the Landmark at Eastview. Construction on the new buildings is anticipated to begin in late 2013 and to be completed in late 2015.

Currently, Regeneron has about 590,000 square feet of space at the Landmark and will occupy another 85,000 square feet of additional space there later this year.

The upcoming expansion will enable the company to continue to accommodate the rapid growth it has experienced over the last six years, company officials said. Regeneron has grown from having 682 employees in 2007 to 2,000 today, including more than 1,300 in Tarrytown.

“Our recently approved drugs and our robust development pipeline have transformed Regeneron into one of the largest and fastest-growing biopharmaceutical companies in the United States,” said CEO Leonard S. Schleifer in a prepared statement.

Gov. Andrew Cuomo said the expansion will further enhance New York”™s reputation as a leader in the biotech industry.
