CMS-PB

Business Context and Reporting Period

This Form 10-Q covers the quarterly period ended March 31, 2010, for CMS Energy Corporation (CMS Energy) and its wholly-owned subsidiary, Consumers Energy Company (Consumers). CMS Energy is a holding company operating primarily in Michigan, with Consumers serving as the regulated electric and gas utility. The company operates in three segments: Electric Utility, Gas Utility, and Enterprises (non-utility investments). The reporting period reflects the impact of a challenging Michigan economy, regulatory proceedings regarding rate cases, and significant capital investment plans under the "Balanced Energy Initiative."

Key Financial Metrics

Segment Performance (Net Income Available to Common Stockholders):

• Electric Utility: $41 million (2010) vs. $39 million (2009).
• Gas Utility: $66 million (2010) vs. $59 million (2009).
• Enterprises: $9 million (2010) vs. $1 million (2009).

Material Changes Versus Prior Period

Net income increased by $15 million year-over-year, driven primarily by favorable rate orders and improved performance in the Enterprises segment, which offset declines in gas deliveries due to mild weather and unfavorable economic conditions.

• Revenue Drivers: Electric and gas revenues increased by $41 million due to rate orders. However, this was partially offset by a $15 million decrease in gas revenue due to mild weather and a $15 million decrease due to unfavorable economic conditions and sales mix.
• Enterprises Growth: The Enterprises segment saw an $8 million increase in net income, attributed to lower fuel costs, increased earnings from equity-method investees, and higher net mark-to-market gains.
• Costs: Maintenance and operating expenses increased due to the implementation of energy optimization programs and voluntary separation plan expenses. Interest charges rose slightly due to higher debt levels.
• Cash Flow: Net cash provided by operating activities increased by $51 million, largely due to higher collections from customers and improved net income, despite lower sales of gas purchased in the prior year.

Guidance, Outlook, and Risks

Outlook and Strategy:

• Capital Investment: Consumers forecasts capital investments exceeding $7 billion from 2010 through 2014. Key projects include a proposed 830 MW coal-fueled plant (subject to regulatory approval and retirement of older units), $570 million in renewable energy investments, and a smart grid program.
• Deliveries: Weather-adjusted electric deliveries are expected to increase by 2% in 2010, while gas deliveries are expected to decline by 2% due to conservation and economic conditions.
• Rate Cases: Consumers filed an application in January 2010 seeking an annual electric revenue increase of $178 million. A gas rate case is pending, with an Administrative Law Judge recommending a $69 million increase versus the $89 million self-implemented by Consumers.

Risks and Contingencies:

• Regulatory Uncertainty: Significant risks exist regarding the recovery of costs for environmental compliance, nuclear fuel storage, and the proposed coal plant. The MPSC ordered a refund of $86 million related to decommissioning funds collected during a 2001-2003 rate freeze; Consumers has appealed this order.
• Environmental Litigation: CMS Energy faces ongoing litigation regarding natural gas price reporting (MDL cases) and environmental remediation obligations at the Bay Harbor site (recorded liability of $74 million).
• Economic Conditions: The downturn in Michigan's automotive industry and high unemployment rates pose risks to customer collections and sales volumes.
• Health Care Reform: New federal legislation resulted in a $3 million increase to CMS Energy's tax expense for the quarter, though it had no effect on Consumers' net income.

Investor Verification Checklist

• Rate Case Outcomes: Verify the final MPSC orders for the pending electric and gas rate cases, specifically the approval of the $178 million electric revenue request and the final determination on the gas rate increase.
• Decommissioning Refund: Monitor the status of the appeal regarding the $86 million refund order for Big Rock decommissioning funds.
• Coal Plant Permit: Track the status of the petition for review of the MDNRE air permit for the proposed 830 MW coal plant and the associated requirement to retire 638 MW of existing capacity.
• Legal Proceedings: Review updates on the multi-district litigation (MDL) regarding natural gas price reporting and the Bay Harbor environmental remediation costs.
• Debt Maturities: Confirm the renewal of revolving credit facilities and the execution of the planned September 2010 private placement of $300 million in First Mortgage Bonds.
