JACKSON, Mich., July 27, 2023 – CMS Energy announced today reported earnings per share of $0.67 for the second quarter of 2023, compared to $0.50 per share for the same quarter in 2022. The company’s adjusted earnings per share for the second quarter of 2023 were $0.75, compared to $0.53 per share for the same quarter in 2022.  For the first six months of the year, the company reported $1.36 per share compared to $1.71 per share for the same timeframe in 2022. On an adjusted earnings per share basis year to date, the company reported $1.45 per share in 2023, compared to $1.73 per share in 2022.

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.

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 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.

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.
