Phillips 66 has appointed Howard Ungerleider, former Dow Inc. President and CFO who oversaw the $86 billion DowDuPont separation into three companies, and Kevin Meyers, ex-ConocoPhillips Senior Vice President of Exploration and Production for the Americas, to its board effective immediately to bolster financial and energy sector expertise.

Long-serving directors Glenn Tilton and Marna Whittington will retire at the May 2026 annual meeting, after which the board will consist of 14 members, 13 of whom are independent. Ungerleider will serve as a Class II director and Meyers as a Class III director alongside existing nominees Gregory J. Hayes, Charles M. Holley and Denise R. Singleton.

Elliott Investment Management, one of Phillips 66’s largest shareholders, supported the board additions and highlighted progress in portfolio focus, capital discipline and mid-continent asset optimization. The investor signaled ongoing engagement to drive execution, capital returns and realization of the company’s full value potential.
