Item 2.02. Results of Operations and Financial Condition.

On April 27, 2023, CMS Energy Corporation (“CMS Energy”) issued a News Release, in which it announced its 2023 first quarter results. Attached as Exhibit 99.1 to this report and incorporated herein by reference is a copy of the CMS Energy first 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, changes in accounting principles, changes in federal 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 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 April 27, 2023, 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 2023 first quarter results and provide a business and financial outlook on April 27 at 9:00 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.

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.

CMS Energy Announces First Quarter Results, Reaffirms

2023 Adjusted EPS Guidance

JACKSON, Mich., April 27, 2023– CMS Energy announced today reported earnings per share of $0.69 for the first quarter of 2023, compared to $1.21 per share for the same quarter in 2022. The company’s adjusted earnings per share for the first quarter of 2023 were $0.70, compared to $1.20 per share for the same quarter in 2022, primarily due to unfavorable weather, which reduced sales volumes, and higher service restoration costs attributable to significant storm activity during the quarter.

CMS Energy reaffirmed its 2023 adjusted earnings guidance of $3.06 to $3.12* 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 of the adjusted EPS growth range.

“Despite a historically warm winter and severe ice storms, we remain confident in our ability to deliver on our full year earnings guidance,” said Garrick Rochow, President and CEO of CMS Energy and Consumers Energy. “We look forward to working with all stakeholders as we look to improve customer reliability through thoughtful investments in our infrastructure.”

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.

CMS Energy will hold a webcast to discuss its 2023 first quarter results and provide a business and financial outlook on Thursday, April 27 at 9:00 a.m. (EDT). To participate in the webcast, go to CMS Energy’s homepage (cmsenergy.com) and select “Events and Presentations.”

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

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, changes in federal 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.

16 16 GAAP Reconciliation CMS Energy provides historical financial results on both a reported (GAAP) and adjusted (non - GAAP) basis and provides forward - lo oking 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 availa ble to common stockholders and references to earnings per share are on a diluted basis. Adjustments could include items such as discontinued operations, asset sales, impairm ents, restructuring costs, business optimization initiative, changes in accounting principles, changes in federal 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 earnin gs as a key measure of the company’s present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Inte rnally, 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 po tential to significantly impact, favorably or unfavorably, the company's reported earnings in future periods, the company is not providing reported earnings guidance nor i s i t providing a reconciliation for the comparable future period earnings. The adjusted earnings should be considered supplemental information to assist in understanding our bu sin ess results, rather than as a substitute for the reported earnings.
