"We are pleased with the additions of Howard and Kevin to the Phillips 66 Board, and we welcome the expertise they will bring," said John Pike, Partner, and Mike Tomkins, Partner, at Elliott Investment Management. "Elliott believes that Phillips 66's asset quality and market position create a compelling opportunity for value creation, and we are encouraged by the Company's efforts to bring fresh perspectives to the Board. While more work must be done, we note the team's focus on execution, capital return and the actions to enhance the Company's advantaged mid-continent position. Our engagement with the Board over the past year has been constructive. As one of Phillips 66's largest investors, we will remain engaged with management and the Board in their work to realize the Company's full value."
