Item 2.02. Results of Operations and Financial Condition.

 

On October 27, 2026, CMS Energy Corporation (“CMS Energy”) issued a News Release, in which it announced its 2026 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 27, 2026, 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 2026 third quarter results and provide a business and financial outlook on October 27 at 10:00 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.

JACKSON, Mich., Oct. 27, 2026 – CMS Energy announced today reported earnings per share of $0.39 for the third quarter of 2026, compared to $0.92 per share for 2025.

Both the quarter and year-to-date GAAP results reflect asset impairment and restructuring activities associated with NorthStar Clean Energy. For the first nine months of the year, the company reported $1.86 per share, compared to $2.59 per share for the same timeframe in 2025. On an adjusted earnings per share basis year to date, the company reported $2.95 per share in 2026, compared to $2.66 per share in 2025.

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.  

 

**Per-share impacts are calculated independently for each reporting period in accordance with ASC 260 and may not be additive due to differences in weighted-average shares outstanding between periods.

 

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.

17 GAAP Reconciliation CMS Energy provides historical financial results on both a reported (GAAP) and adjusted (non-GAAP) basis and provides forward-looking guidance on an adjusted basis. During an oral presentation, references to “earnings” are on an adjusted basis. 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 estimatethe 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 adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for the reported earnings. 17
