Item 2.02. Results of Operations and Financial Condition.
On October 30, 2025, CMS Energy Corporation (“CMS Energy”) issued a News Release, in which it announced its 2025 third quarter results. Attached as Exhibit 99.1 to this report and incorporated herein by reference is a copy of the CMS Energy News Release, furnished as a part of this report.
Exhibit 99.1 contains certain financial measures that are considered “non-GAAP financial measures” as defined in Securities and Exchange Commission rules. Other than forward-looking earnings guidance, Exhibit 99.1 contains a reconciliation of these non-GAAP financial measures to their most directly comparable financial measures calculated and presented in accordance with accounting principles generally accepted in the United States. 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. Management views adjusted earnings as a key measure of CMS Energy’s present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Internally, CMS Energy uses adjusted earnings to measure and assess performance. Because CMS Energy is not able to estimate the impact of specific line items, which have the potential to significantly impact, favorably or unfavorably, reported earnings in future periods, Exhibit 99.1 does not contain reported earnings guidance nor a reconciliation for the comparable future period earnings. The adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for the reported 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.
Item 7.01. Regulation FD Disclosure.
The information set forth in the CMS Energy News Release dated October 30, 2025, attached as Exhibit 99.1, is incorporated by reference in response to this Item 7.01.
CMS Energy will hold a webcast to discuss its 2025 third quarter results and provide a business and financial outlook on October 30 at 9:30 a.m. (ET). A copy of the CMS Energy presentation is furnished as Exhibit 99.2 to this report. A webcast of the presentation will be available on the CMS Energy website, www.cmsenergy.com.
In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, including Exhibits 99.1 and 99.2, shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933.

CMS Energy Announces Strong Third Quarter Results, Raises 2025 Adjusted EPS, Initiates 2026 Guidance
JACKSON, Mich., Oct. 30, 2025 – CMS Energy announced today reported earnings per share of $0.92 for the third quarter of 2025, compared to $0.84 per share for 2024. The company’s adjusted earnings per share for the third quarter were $0.93, compared to $0.84 per share for the same quarter in 2024. For the first nine months of the year, the company reported $2.59 per share compared to $2.45 per share for the same timeframe in 2024. The company’s adjusted earnings per share on a year-to-date basis were $2.66 in 2025, compared to $2.47 in 2024, largely due to constructive regulatory outcomes and favorable weather.
CMS Energy raised its 2025 adjusted earnings guidance to $3.56 to $3.60 per share from $3.54 to $3.60 per share* (*See below for important information about non-GAAP measures). The company also initiated 2026 adjusted earnings guidance of $3.80 to $3.87 per share and reaffirmed its long-term adjusted EPS growth of 6 to 8 percent, with continued confidence toward the high end.
“CMS Energy continues to build on its strong track record of constructive regulatory outcomes, as demonstrated by recent orders in our natural gas rate case and Renewable Energy Plan filing,” said Garrick Rochow, President and CEO of CMS Energy and Consumers Energy. “With a clear plan for long-term customer value and earnings growth, the company is well positioned to achieve our operational and financial goals for all stakeholders.”

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, 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. 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.

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.

During an oral presentation, references to “earnings” are on an adjusted basis. All references to net income ref er to net income available to common stockholders and references to earnings per share are on a diluted basis. Adjustments could include items such as disc ont inued operations, asset sales, impairments, restructuring costs, business optimization initiative, major enterprise resource planning software implementatio ns, changes in accounting principles, voluntary separation program, changes in federal and state tax policy, regulatory items from prior years, unrealized gains or lo sses from mark - to - market adjustments, recognized in net income related to NorthStar Clean Energy's interest expense, or other items. Management views adj usted earnings as a key measure of the company’s present operating financial performance and uses adjusted earnings for external communications with ana lysts and investors.
