Career

Early Career and Rise at Phillips 66

Before becoming CEO of Phillips 66, Mark Lashier served as the company's Chief Operating Officer (COO). In April 2022, Phillips 66 announced that Lashier, in his capacity as COO, would succeed Greg Garland as CEO effective July 2022. Garland, who had led the company since its spin-off from ConocoPhillips in 2012, transitioned to the role of executive chairman of the board. The succession plan was reported by Reuters and other major financial news outlets as a significant leadership transition for one of the largest downstream energy companies in the United States. The appointment signaled continuity in corporate strategy while placing operational leadership in Lashier's hands.

Lashier subsequently assumed the combined title of Chairman and CEO of Phillips 66, a designation reflected in the company's public communications and media appearances from 2025 onward.

Leadership of Phillips 66

As Chairman and CEO, Lashier has led Phillips 66 through a period characterized by volatile energy markets, shifting demand patterns, and strategic repositioning. Phillips 66 operates across multiple segments of the energy value chain, including refining, midstream, chemicals, and marketing and specialties.

In a September 2025 article published on the Phillips 66 corporate newsroom, Lashier outlined his strategic vision for the company under the headline "Today & Tomorrow: Driving long-term value." The piece described how strategy, integration, and culture converge under Lashier's leadership, with the CEO sharing his perspective on how Phillips 66 is "positioned to thrive in a competitive" energy environment. The article emphasized the importance of long-term value creation, operational integration across the company's business segments, and the role of corporate culture in sustaining competitive performance.

Lashier has been a frequent presence in financial media, discussing the company's performance and broader energy market conditions. In July 2025, he appeared on CNBC's Squawk Box to discuss Phillips 66's strong second quarter performance for that year. The appearance highlighted the company's financial results and Lashier's perspective on market dynamics affecting refining and downstream operations.

In December 2025, the Phillips 66 newsroom noted that both Lashier and Chief Financial Officer Kevin Mitchell discussed energy market conditions and company priorities in appearances on Bloomberg Television and Yahoo! Finance.

Views on the Chemicals Business

Lashier has spoken publicly about the cyclical nature of the chemicals industry, a significant segment of Phillips 66's operations through its joint venture Chevron Phillips Chemical. In a February 2026 appearance on Bloomberg Television, Lashier stated that the chemicals business was "at the bottom of a very tough cycle," while expressing long-term optimism about the segment's prospects. This assessment reflected broader industry conditions, as global petrochemical markets experienced oversupply and compressed margins during this period. Lashier's commentary indicated a belief that the downturn was cyclical rather than structural, and that Phillips 66's chemicals-related investments would generate returns as market conditions improved.

Views on the Energy Market

Lashier has shared his views on the state of global energy markets in several high-profile media appearances. In a January 2026 interview on the At Barron's podcast, hosted by Andy Serwer, Lashier discussed a range of topics including the global energy market outlook, Venezuela's oil and gas resources, and Phillips 66's stock performance relative to the S&P 500 index. During the interview, Lashier also offered his thoughts on the Paramount+ television series Landman, which dramatizes the oil and gas industry in West Texas. The appearance was subsequently highlighted by Phillips 66's corporate communications, which described Lashier's "small-town roots" and "big-picture insights" on the energy sector.

These public appearances have positioned Lashier as a prominent spokesperson for the downstream and petrochemical segments of the energy industry, offering perspective on topics ranging from geopolitical influences on energy supply to domestic production trends and corporate strategy.

Board Membership at Motorola Solutions

On November 18, 2025, Motorola Solutions announced that Lashier had been appointed to its board of directors. Motorola Solutions, a company focused on safety and security technologies, described Lashier's appointment as strengthening its board governance. The appointment was also reported by Investing.com, which identified Lashier by his role as Phillips 66 CEO. Board service at major publicly traded corporations outside of one's primary company is a common practice among senior executives, often reflecting the individual's standing in the broader business community.

Recognition

Lashier's leadership of Phillips 66 has drawn attention from major financial media outlets, including CNBC, Bloomberg Television, Barron's, and Yahoo! Finance. His appearances on programs such as CNBC's Squawk Box and the At Barron's podcast have provided platforms for discussing both company-specific and industry-wide topics. His appointment to the Motorola Solutions board of directors in 2025 represented recognition of his executive experience and leadership beyond the energy sector.
