Northbrook, Ill., September 17, 2019 – UL and parent company Underwriters
Laboratories today announced that, after 15 years of service, Keith Williams has decided to retire as president and CEO. Mr. Williams will continue to support each organization through an interim period to ensure a smooth transition.

The UL Board of Directors has appointed Jennifer Scanlon as president and CEO of UL and a member of the UL Board of Directors, effective September 30, 2019. Ms. Scanlon most recently served as president, CEO and a director of USG Corporation, a 116-year old innovative building products manufacturer and one of UL’s oldest clients. Over her 16-year career at USG, Ms. Scanlon led the company through some of its most significant strategic moves, including establishing the global joint venture, USG Boral Building Products, and divesting L&W Supply. In 2018, she negotiated the sale of USG to Knauf for $7 billion, which represented a 76 percent premium to the Company’s stock
price compared to when Ms. Scanlon was named CEO. The transaction closed April 24, 2019. She is the first woman to serve as president and CEO of UL.
