Business Context and Reporting Period

This Form 10-K covers the fiscal year ended December 31, 2004, for Alliant Energy Corporation (Alliant Energy) and its primary subsidiaries: Interstate Power and Light Company (IPL) and Wisconsin Power and Light Company (WPL). Alliant Energy operates as a registered public utility holding company under the Public Utility Holding Company Act of 1935 (PUHCA). Its core business consists of regulated electric and natural gas utilities serving customers in Iowa, Wisconsin, Minnesota, and Illinois. The company also maintains non-regulated businesses through Alliant Energy Resources, Inc., with investments in international energy markets (Brazil, China, New Zealand) and domestic non-regulated generation.

Key Financial Metrics (2004)

Material Changes vs. Prior Period

• Revenue Growth: Consolidated operating revenues increased 3.2% to $2,958.7 million from $2,866.8 million in 2003. Domestic utility electric revenues rose 5% and gas revenues rose 1%.
• Net Income Decline: Net income decreased 20.7% to $145.5 million from $183.5 million in 2003. This decline was primarily driven by a $65.3 million loss from discontinued operations (compared to a $33.5 million gain in 2003) related to the divestiture of non-regulated businesses (e.g., Whiting Petroleum, Australian business, energy services).
• Continuing Operations Improvement: Income from continuing operations increased 35.1% to $210.8 million, driven by higher domestic utility margins, a lower effective income tax rate (26.7% vs. 28.5%), and improved results from non-regulated businesses.
• Weather Impact: Extremely mild weather in 2004 negatively impacted earnings by an estimated $22 million to $25 million, reducing electric and gas sales volumes.
• Divestitures: The company completed the sale of its remaining interest in Whiting Petroleum Corporation and divested its gas marketing and energy management services businesses, classifying them as discontinued operations.

Guidance, Outlook, and Risks

Management Commentary and Outlook

• Strategic Focus: Alliant Energy is narrowing its strategic focus to its core domestic utility business (IPL and WPL) as the primary growth platform. Non-regulated businesses are being streamlined, with ongoing divestitures of assets such as oil and gas gathering pipelines and biomass facilities.
• Generation Plan: The company plans to add 1,600 MW of domestic generating capacity by 2010. Key projects include the 565 MW Emery Generating Station (placed in service May 2004) and a 300 MW natural gas facility under construction in Sheboygan Falls, Wisconsin.
• Nuclear Sales: Alliant Energy is actively pursuing the sale of its interests in two nuclear facilities: IPL's 70% interest in the Duane Arnold Energy Center (DAEC) and WPL's 41% interest in the Kewaunee Nuclear Power Plant. The sale of Kewaunee to Dominion Resources is pending final regulatory approval from the Public Service Commission of Wisconsin (PSCW).
• Capital Structure: The company aims to maintain a consolidated debt-to-total capitalization ratio of approximately 50% and maintain investment-grade credit ratings.

Risks and Contingencies

• Regulatory Risk: Future earnings depend on the ability to obtain timely rate relief from state commissions (IUB, PSCW, MPUC, ICC) to recover costs and earn a reasonable return. Pending rate cases in Iowa and Wisconsin are critical.
• Environmental Compliance: Significant capital investments may be required to comply with evolving federal and state environmental regulations, including the Clean Air Interstate Rule, mercury emission standards, and water quality regulations (e.g., EPA 316(b)).
• International Investments: Investments in Brazil face regulatory and political risks. Alliant Energy is involved in arbitration with Brazilian partners regarding shareholder rights and facility expansions. Currency exchange fluctuations also impact the valuation of foreign investments.
• Asset Valuation: The company faces potential impairment charges related to its China investments due to rising coal costs and the Laguna del Mar resort project in Mexico, where ownership was transferred to Alliant Energy in early 2005 to maximize recovery.
• Plant Outages: Unplanned outages, such as the transformer failure at the Ottumwa Generating Station (announced Feb 2005) and the Kewaunee backup cooling system issue, could impact reliability and increase purchased power costs.

Investor Verification Checklist

• Discontinued Operations: Verify the final tax and cash flow impacts of the divested non-regulated businesses (Whiting Petroleum, Australian assets, energy services) to understand the true recurring earnings power.
• Nuclear Sale Status: Monitor the PSCW's final decision on the sale of WPL's Kewaunee interest and the progress of the DAEC sale, as these transactions are critical to reducing nuclear liability and operational risk.
• Rate Case Outcomes: Track the final orders for the 2004/2005 retail rate cases in Iowa (IPL) and Wisconsin (WPL) to confirm the recovery of increased operating costs and capital investments.
• Environmental Capital Expenditures: Assess the magnitude of future capital requirements for compliance with new mercury and air quality regulations, which could impact free cash flow.
• China Investment Valuation: Review the recoverability of investments in China given the reported increase in coal and transportation costs and the potential for goodwill impairment.
• Dividend Sustainability: Confirm that the increased quarterly dividend ($0.2625/share) remains sustainable given the company's target payout ratio of 60-70% of utility earnings.
