Laboratory chemicals maker Sigma-Aldrich Corp. (SIAL) said Wednesday that its Chief Administrative Officer and Chief Financial Officer Michael Hogan will retire at a date to be determined this summer.
Hogan had advised the company early this year that he planned to retire as soon as a successor was identified and successfully transitioned. He turned 55 in April.
The St. Louis, Missouri-based company said it has begun a search for Hogan's successor from a pool of internal and external candidates.
After his retirement, Hogan will continue to assist the company with its charitable activities as an unpaid Vice President and outside Director of the independent Sigma-Aldrich Foundation, which he co-founded with Chairman David Harvey in 2004.
Sigma-Aldrich shares closed Wednesday's regular trading session at $59.74, up 91 cents or 1.55%.
