About

In a defining leadership development, Marathon Petroleum's board elected CEO Maryann T.

Marathon Petroleum's large-scale refining system (including the Galveston Bay refinery in Texas City as the largest US refinery at 631,000 barrels/day) processes crude oil into gasoline, diesel, jet fuel, and specialty products distributed through branded Speedway (sold to 7-Eleven in 2021) and independent dealer networks and MPLX's logistics infrastructure.

About
CMS Energy Corporation is a Jackson, Michigan-based regulated electric and gas utility holding company — publicly traded on the New York Stock Exchange (NYSE: CMS) as an S&P 500 Utilities component — serving approximately 6.8 million electric and 1.8 million natural gas customers throughout Michigan through its principal subsidiary Consumers Energy (Michigan's largest utility, serving 68 of Michigan's 83 counties) through approximately 7,500 employees. In fiscal year 2024, CMS Energy reported revenues of approximately $8.4 billion and adjusted EPS of approximately $3.29, growing within the company's 6-8% annual adjusted EPS guidance range that has made CMS Energy one of the most consistent earnings growth utilities in the US — delivering 18 consecutive years of meeting or exceeding earnings guidance under the management team's "CE Way" lean operational improvement program. CEO Garrick Rochow leads CMS Energy's strategy of executing a $20+ billion capital plan (2024-2028) focused on renewable energy generation (wind and solar replacing coal-fired generation ahead of the Michigan Public Service Commission's clean energy mandate), electric distribution grid hardening (replacing 1,750 miles of distribution lines annually to reduce storm outage frequency and duration), and natural gas infrastructure modernization. Michigan's Governor Whitmer's 100% clean energy by 2040 mandate (PA 235 — enacted 2023) requires Consumers Energy to retire coal plants, add significant renewable energy generation, and build battery storage — translating directly into approved rate base capital investment that earns Consumers Energy's authorized return on equity (approximately 9.9%).
