“On behalf of the Board of Directors, I want to thank Greg for his outstanding leadership as Chairman and CEO,” Tilton continued. “He stood up Phillips 66 as an independent company and created a leading diversified energy manufacturing and logistics company, while investing for the future and delivering strong financial returns.”

Lashier joined Phillips 66 in April 2021 as President and Chief Operating Officer.

“Mark is the right leader at the right time for Phillips 66,” Garland said. “He has demonstrated a strong track record of delivering growth and driving excellence in both financial and operating results. He will lead a company that has a solid strategy, proven track record, strong leadership, outstanding employees and will successfully navigate and thrive in the energy transition.”

“I have known Mark a long time,” continued Garland. “We have a great relationship based on trust and respect, and I am confident he will serve Phillips 66, our employees, our communities and our shareholders well.”

Lashier said he planned to continue to build on the success Garland has had since the company was established in 2012.

“Greg’s leadership in fostering a culture of operating excellence and financial strength will benefit us for decades,” Lashier said. “That foundation is critical as we face the opportunities and challenges of the next 10 years.
