[GRAPHIC OMITTED] [ALLIANT ENERGY] Alliant Energy Worldwide Headquarters 222 W. Washington Ave. P.O. Box 192 Madison, WI 53701-0192 www.alliantenergy.com News Release -------------------------------------------------------------------- FOR IMMEDIATE RELEASE Media Contact: Chris Schoenherr (608) 252-3924 Karen Whitmer (608)252-4839 Finance Contact: Eric Mott (608) 252-3391 ALLIANT ENERGY REPORTS STRONG THIRD QUARTER 2001 EARNINGS On track to meet earnings targets for 2001 MADISON, Wis. - Oct. 19, 2001 - Alliant Energy Corp. (NYSE: LNT) today reported adjusted net income of $74.9 million, or $0.94 per share, for the third quarter of 2001 compared to adjusted net income of $73.5 million, or $0.93 per share, for the third quarter of 2000. Both periods excluded non-cash valuation adjustments related to the company's obligation under certain 30-year exchangeable senior notes - charges of $0.16 per share and $0.02 per share in the third quarters of 2001 and 2000, respectively. In addition, adjusted net income for the third quarter of 2000 excludes $204 million of non-cash net income, or $2.58 per share, relating to the company's adoption of a new accounting pronouncement (SFAS No. 133) on July 1, 2000. Higher electric utility margins, a lower effective income tax rate and higher earnings from the company's non-regulated operations were largely offset by increased utility operating expenses during the quarter. "I am pleased to report another solid quarter of financial performance," said Alliant Energy CEO Erroll B. Davis, Jr. "Through the successful execution of our Invest, Connect and Grow strategy, we continue to deliver strong earnings and shareowner value through both our regulated utility operations and our portfolio of non-regulated businesses." Reported net income and earnings per share for the third quarters of 2001 and 2000 were $62.3 million, or $0.78 per share, and $276.2 million, or $3.49 per share, respectively. Alliant Energy is the parent company of three public utility companies - IES Utilities Inc. (IES), Interstate Power Company (IPC) and Wisconsin Power and Light Company (WP&L) - and of Alliant Energy Resources, Inc. (AER), the parent company of Alliant Energy's non-regulated operations. A reconciliation of Alliant Energy's unaudited third quarter 2001 versus 2000 earnings per share (EPS) is as follows: EPS as reported - third quarter 2000 $3.49 Less: SFAS No. 133 adoption non-cash income (2.58) Plus: non-cash valuation charge .02 ------ Adjusted third quarter 2000 EPS .93 ------------------------------------------------------------------------------------------ 3Q 2001 EPS increase/(decrease) versus 2000: Utility operations: Electric margins $0.08 Effective income tax rate .07 Operating expenses (.17) Other .04 ------ Total utility operations .02 Non-regulated operations: Integrated Services business unit .02 Investments business unit .01 International business unit .01 Generation and Trading business unit (.05) Lower short-term debt rates/other .04 ------ Total non-regulated operations .03 Parent expenses/other (.04) ------ ------------------------------------------------------------------------------------------ Adjusted third quarter 2001 EPS $0.94 Less: non-cash valuation charge (.16) ------ EPS as reported - third quarter 2001 $0.78 ====== Utility Operations Third quarter 2001 utility earnings were $69.5 million ($0.88 per share) compared to $68.4 million ($0.86 per share) for the same period in 2000. The increase in electric margin was primarily related to increased residential and commercial sales due to more favorable weather conditions in the third quarter of 2001 compared to the same period in 2000 and continued retail customer growth. Higher energy conservation revenues also contributed to the increase. The increased operating expenses were largely due to higher costs in the company's energy delivery and generation business units (certain increases were timing differences), increased uncollectible customer account balances, higher operating costs at the Kewaunee Nuclear Power Plant and costs associated with the implementation of the company's e-business strategy. Non-regulated Operations Alliant Energy's non-regulated operations reported adjusted net income of $8.2 million ($0.10 per share) in the third quarter of 2001 compared to adjusted net income of $5.3 million ($0.07 per share) in the third quarter of 2000. These figures exclude the non-cash valuation charges of $12.6 million ($0.16 per share) and $1.2 million ($0.02 per share) in 2001 and 2000, respectively, and the $204 million of non-cash net income ($2.58 per share) in 2000 relating to the company's adoption of a new accounting pronouncement (SFAS No. 133) on July 1, 2000. Reported net income/(loss) and earnings per share for 2001 and 2000 were ($4.4) million, or ($0.06) per share, and $208.0 million, or $2.63 per share, respectively. The improved results from the Integrated Services business unit were largely due to a one-time charge related to a loss on a contract in the third quarter of 2000. The higher income from the Investments business unit was from the company's oil and gas operations and was largely due to increased sales volumes as a result of the continued acquisition of additional oil and gas producing properties. The improved results from the International business unit were due to increased earnings from the company's China and Australian investments. The increase for China was largely due to the addition of five combined heat and power facilities to the company's China portfolio in the past twelve months and increased income tax benefits. The earnings from the Australian operations included non-cash income from the valuation of certain of its energy agreements. These increases were partially offset by lower earnings from the company's New Zealand investments due to the impact of a drought in New Zealand and an asset sale gain the company realized in the third quarter of 2000. In spite of the drought conditions in Brazil, the company's results from its Brazil investments were flat in the third quarter of 2001 compared to the same period in 2000. The lower earnings from our Generation and Trading business unit were largely the result of reduced income from the company's electricity trading joint venture due to fewer weather-related trading opportunities in the third quarter of 2001. The non-cash valuation charge in both periods was related to the net valuation of the 30-year exchangeable senior notes and the associated McLeodUSA shares designated as trading securities. Future Earnings Outlook Thomas M. Walker, Alliant Energy's Chief Financial Officer stated, "Alliant Energy's guidance for adjusted earnings per share for 2001 is in the range of $2.40 - $2.50 per share. Also, our initial guidance for adjusted earnings per share for 2002 is in the range of $2.50 - $2.70 per share. By executing our strategic plan, our goal is to deliver 7%-10% annual earnings growth, enhanced shareowner value and meet our financial objectives, including maintaining our stable dividend." Drivers for Alliant Energy's earnings estimates include, but are not limited to: >> Normal weather conditions in its utility service territories >> Continued economic development and sales growth in its utility service territories >> Continued cost control and operational efficiencies in its utility operations >> Ability of its utility subsidiaries to recover their operating costs, and to earn a reasonable rate of return, in future rate proceedings >> Ability to recover its purchased power and fuel costs, both domestically and internationally >> Ability to offset start-up and growth-related interest expenses in its non-regulated businesses with sales of non-strategic assets and to redeploy such proceeds into more strategic earnings-generating investments >> Continued improved profitability of its international investments >> Continued improved profitability of its non-regulated businesses as a whole, including oil and gas, electricity trading, integrated energy and transportation services >> Stable oil and gas prices >> Other stable business conditions, including a stable economy Alliant Energy's strategic plan includes investing in generation and other energy-related projects; better connecting with customers through enhanced service reliability, value-added products and services, and e-business initiatives; and growing the non-regulated side of its business through partnerships and acquisitions in generation projects, international markets and other strategic initiatives. Alliant Energy's goal is to have its non-regulated businesses contribute more than 25 percent of its earnings within the next three years and believes that successful implementation of these strategies will contribute significantly to the company achieving its targeted annual growth rate of 7-10 percent in adjusted earnings. --- --- --- Alliant Energy, through its subsidiaries and partners, provides electricity, natural gas, water and steam to over three million customers worldwide.
