Celgene names new chief financial officer

* Jacqualyn Fouse to replace David Gryska on Sept. 27

* Fouse previously was CFO at Bunge Ltd and Alcon Labs

* Gryska to leave company on Nov. 1

CHICAGO (Reuters) - Celgene Corp <CELG.O> said on Thursday it named Jacqualyn Fouse chief financial officer, effective Sept. 27, to replace David Gryska, who will leave the company on Nov. 1 to pursue other opportunities.

Fouse joins the Summit, New Jersey-based pharmaceutical company from agribusiness and food company Bunge Ltd . She was chief financial officer there for the past 3 years. She was chief financial officer at eye care company Alcon Laboratories Inc from 2002 to 2007 and was group treasurer of Nestle SA , Alcon Inc's majority owner, before that.

"We believe the CFO transition likely represents part of Celgene's evolution from a mid-cap U.S. focused growth company to a large-cap international company," ISI Group analyst Mark Schoenebaum wrote in a research note.

"This is important, as we expect international sales to account for over half of Celgene's business within 3 to 5 years. Ms. Fouse brings international experience and strategic perspective to Celgene," he said, adding that he believes the CFO transition was "probably planned at the board level and does not represent a surprise to the company."
