CMS Energy Exceeds Earnings Guidance in 2025, Raises 2026 Adjusted EPS Guidance

JACKSON, Mich., Feb. 5, 2026 – CMS Energy announced today reported earnings per share of $3.53 for 2025, compared to $3.33 per share for 2024. The company’s adjusted earnings per share for 2025 were $3.61, compared to $3.34 per share for 2024, exceeding the guidance range largely due to outperformance at NorthStar Clean Energy. CMS Energy also increased its annual dividend by 11 cents per share to $2.28 for 2026, the 20th increase in as many years.

CMS Energy raised its 2026 adjusted earnings guidance to $3.83 to $3.90 from $3.80 to $3.87 per share (*See below for important information about non-GAAP measures) and reaffirmed long-term adjusted EPS growth of 6 to 8 percent, with continued confidence toward the high end.

“CMS Energy had a successful year delivering for all stakeholders in 2025. Our accomplishments include constructive regulatory outcomes, solid cost performance at the Utility and strong results at NorthStar,” said Garrick Rochow, President and CEO of CMS Energy and Consumers Energy. “Our customers remain our top priority as the CMS Energy team works every day to improve reliability and affordability.”

CMS Energy (NYSE: CMS) is a Michigan-based energy provider featuring Consumers Energy as its primary business. It also owns and operates independent power generation businesses.

Important information for investors about non-GAAP measures and other disclosures.

This news release contains non-Generally Accepted Accounting Principles (non-GAAP) measures, such as adjusted earnings. All references to net income refer to net income available to common stockholders and references to earnings per share are on a diluted basis. Adjustments could include items such as discontinued operations, asset sales, impairments, restructuring costs, business optimization initiative, changes in accounting principles, voluntary separation program, changes in federal tax policy, regulatory items from prior years, unrealized gains or losses from mark-to-market adjustments, or other items. Management views adjusted earnings as a key measure of the company's present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Internally, the company uses adjusted earnings to measure and assess performance. Because the company is not able to estimate the impact of specific line items, which have the potential to significantly impact, favorably or unfavorably, the company's reported earnings in future periods, the company is not providing reported earnings guidance nor is it providing a reconciliation for the comparable future period earnings. The company's adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for the reported earnings.

This news release contains "forward-looking statements." The forward-looking statements are subject to risks and uncertainties that could cause CMS Energy's and Consumers Energy's results to differ materially. All forward-looking statements should be considered in the context of the risk and other factors detailed from time to time in CMS Energy's and Consumers Energy's Securities and Exchange Commission filings.

Investors and others should note that CMS Energy routinely posts important information on its website and considers the Investor Relations section, www.cmsenergy.com/investor-relations, a channel of distribution.

Management views adjusted (non-Generally Accepted Accounting Principles) earnings as a key measure of the Company's present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Internally, the Company uses adjusted earnings to measure and assess performance. Adjustments could include items such as discontinued operations, asset sales, impairments, restructuring costs, business optimization initiative, major enterprise resource planning software implementations, changes in accounting principles, voluntary separation program, changes in federal and state tax policy, regulatory items from prior years, unrealized gains or losses from mark-to-market adjustments, recognized in net income related to NorthStar Clean Energy's interest expense, or other items. The adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for reported earnings.
