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. Adjustments could include items such as discontinued operations, asset sales, impairments, restructuring costs, regulatory items from prior years, or other items detailed in the attached summary financial statements. 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 adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for the reported earnings. Adjusted weather-normalized earnings are provided to show the impact of deviations from normal weather.

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.
