BMO Utility Conference

November 29, 2011

This presentation is made as of the date hereof and contains “forward-looking statements” as defined in Rule 3b-6 of the Securities Exchange Act of 1934, as amended, Rule 175 of the Securities Act of 1933, as amended, and relevant legal decisions. The forward-looking statements are subject to risks and uncertainties. They should be read in conjunction with “FORWARD-LOOKING STATEMENTS AND INFORMATION” and “RISK FACTORS” sections of CMS Energy’s and Consumers Energy’s Form 10-K for the year ended December 31 and as updated in subsequent 10-Qs. CMS Energy’s and Consumers Energy’s “FORWARD-LOOKING

STATEMENTS AND INFORMATION” and “RISK FACTORS” sections are incorporated herein by reference and discuss important factors that could cause CMS Energy’s and Consumers Energy’s results to differ materially from those anticipated in such statements. CMS Energy and Consumers Energy undertake no obligation to update any of the information presented herein to reflect facts, events or circumstances after the date hereof.

The presentation also includes non-GAAP measures when describing CMS Energy’s results of operations and financial performance. A reconciliation of each of these measures to the most directly comparable GAAP measure is included in the appendix and posted on our website at www.cmsenergy.com.

Reported earnings could vary because of several factors, such as legacy issues associated with prior asset sales. Because of those uncertainties, the company is not providing reported earnings guidance.

GAS RATE CASE U-16855*

On September 2, 2011, Consumers Energy filed an application with the Michigan Public Service Commission seeking an increase in its gas delivery and transportation rates based on a 12 month ending December, 2012 test year. The request seeks authorization to implement an uncollectible accounts expense tracker as well as OPEB and Pension trackers. The proposed capital structure includes a 10.70% authorized return on equity. If approved, the request would add about $1.80 per month, or about 2.2%, to the typical residential customer’s average monthly bill. The $49 million revenue deficiency is detailed below.
