Career

Rise to CEO of Phillips 66

Mark Lashier's path to the top leadership position at Phillips 66 was formalized in April 2022, when the company announced that Lashier, then serving as COO, would succeed Greg Garland as CEO effective July 2022. Garland, who had led the company since its spinoff from ConocoPhillips in 2012, transitioned to the role of chairman of the board. The succession plan signaled a deliberate leadership transition, with Lashier having already been deeply involved in the company's operations and strategic direction in his capacity as COO.

The appointment reflected the Phillips 66 board's confidence in Lashier's ability to guide the company through an evolving energy landscape. At the time of his appointment, the global energy industry was contending with the aftermath of the COVID-19 pandemic's impact on demand, shifting geopolitical dynamics, and growing discussions about energy transition and decarbonization.

Leadership at Phillips 66

As CEO and later Chairman and CEO, Lashier has overseen Phillips 66's operations across its diversified business segments, which include refining, midstream, chemicals, and marketing and specialties. Under his leadership, the company has pursued a strategy centered on operational excellence, portfolio optimization, and long-term value creation for shareholders.

In a September 2025 corporate communication, Lashier outlined how strategy, integration, and culture converge in Phillips 66's approach to remaining competitive in the energy sector. He articulated a vision for how the company is positioned to thrive in a competitive and changing energy environment.

Lashier has been candid about the cyclical nature of portions of Phillips 66's business. In a February 2026 appearance on Bloomberg Television, he discussed the state of the company's chemicals business, stating that it was at the bottom of a "very tough cycle" while expressing confidence in the long-term outlook for the sector. This assessment reflected both the broader downturn in the global petrochemical market and Lashier's approach of providing transparent assessments of business conditions to investors and the public.

In July 2025, Lashier appeared on CNBC's "Squawk Box" to discuss Phillips 66's second quarter performance, which the company characterized as strong. His regular appearances on financial media platforms have served as a means of communicating the company's strategic priorities and financial performance to analysts, investors, and the broader public.

In December 2025, both Lashier and Phillips 66 Chief Financial Officer Kevin Mitchell appeared on Bloomberg and Yahoo! Finance to discuss energy market conditions and the company's priorities heading into the new year.

Public Commentary on the Energy Industry

Lashier has emerged as a notable commentator on the state of the energy industry, offering perspectives on global supply dynamics, geopolitical factors affecting energy markets, and the trajectory of the sector. In a January 2026 appearance on the At Barron's podcast hosted by Andy Serwer, Lashier discussed a range of topics including the state of the energy market, Venezuela's energy resources, and the company's stock performance relative to the S&P 500 index. He also shared his thoughts on the Paramount+ television series Landman, which dramatizes life in the oil and gas industry.

A Phillips 66 corporate summary of the podcast appearance noted that Lashier drew on his "small-town roots" and "big-picture insights" during the wide-ranging conversation. This framing suggests Lashier's personal background in a smaller community has informed his perspective on the energy industry and its role in American economic life.

Board Membership at Motorola Solutions

On November 18, 2025, Motorola Solutions announced the appointment of Mark Lashier to its board of directors. Motorola Solutions is a global company specializing in safety and security technologies, and the appointment reflected the company's interest in adding leadership experience from the energy sector to its governance structure. The appointment was reported by multiple financial news outlets, including Investing.com, which noted Lashier's concurrent role as CEO of Phillips 66.

Service on external corporate boards is common among Fortune 500 CEOs, and Lashier's appointment to the Motorola Solutions board placed him in a governance role at a second major publicly traded company.

Personal Life

Phillips 66's characterization of his "small-town roots" on the occasion of his Barron's podcast appearance suggests he grew up in a smaller American community, though specific details about his hometown or upbringing have not been extensively documented in the available public record. This background has been referenced as informing his worldview and approach to business leadership within the energy sector.
