(NYSE: LNT) today reported income (loss) and earnings per share (EPS) from continuing operations for the second quarter of 2003 of $11.7 million and $0.13, respectively, compared to ($5.5) million and ($0.06) for the same period in 2002. Alliant Energy's net income and EPS for the second quarter of 2003 were $32.2 million and $0.35, respectively, compared to $6.3 million and $0.07 for the same period in 2002. Additional details regarding Alliant Energy's second quarter unaudited earnings are as follows (net income in millions; totals may not foot due to rounding): Q2 2003 * Q2 2002 ------------------------- ---------------------------- Earnings from continuing operations: Net Income EPS Net Income EPS ------------------------- ---------------------------- Utility $ 22.6 $ 0.25 $ 26.9 $ 0.30 Non-regulated (Alliant Energy Resources) (2.2) (0.02) (25.5) (0.28) Parent and other (primarily taxes, interest and A&G) (8.7) (0.10) (6.9) (0.08) ------------------------- ---------------------------- Total earnings from continuing operations 11.7 0.13 (5.5) (0.06) Earnings from discontinued operations: ** Operating results 5.8 0.06 6.0 0.07 Gain on sale of discontinued operations 40.7 0.44 - - Non-cash valuation and other accounting adjustments: Southern Hydro SFAS 133 income (loss) (0.1) - 5.8 0.06 Discontinuing depreciation, depletion and amortization of assets held for sale 6.9 0.07 - - Valuation adjustments and selling costs (32.9) (0.35) - - ------------------------- ---------------------------- Total earnings from discontinued operations 20.4 0.22 11.8 0.13 ------------------------- ---------------------------- Net income $ 32.2 $ 0.35 $ 6.3 $ 0.07 ========================= ============================ * The 2003 EPS amounts have been computed based on the average shares outstanding in 2002. Alliant Energy reports the dilutive impact of increased shares outstanding as a separate earnings variance item if it is material. ** Alliant Energy has classified its oil and gas, affordable housing, Australian and SmartEnergy businesses as assets held for sale and discontinued operations. The lower utility earnings from continuing operations were largely due to milder weather conditions in the second quarter of 2003 compared to the same period in 2002. The positive impact on electric utility margin of several rate increases implemented in the last twelve months was largely offset by higher utility operating expenses and a higher utility effective income tax rate. The significant improvement in non-regulated results from continuing operations was primarily due to a $0.19 per share increase in the results from Alliant Energy's International business unit and $0.11 per share of asset valuation charges recorded in the second quarter of 2002. Alliant Energy - Second Quarter 2003 Earnings Page 2 of 6 July 28, 2003 Alliant Energy continued to successfully execute its planned asset divestitures by closing on the sale of its Australian business in April and its affordable housing and SmartEnergy businesses in July. Alliant Energy recorded an after-tax gain on the sale of its Australian business of $41 million in the second quarter of 2003. In addition, the second quarter of 2003 results reflect after-tax charges of $33 million for valuation adjustments to reflect updated estimates of the market value of the $634 million of assets it had classified as assets held for sale as of June 30, 2003 as well as selling costs related to the asset divestitures. "Clearly we have made significant progress executing on the plan we announced in November 2002 to strengthen our financial profile," said Erroll B. Davis, Jr., chairman, president and CEO of Alliant Energy. "This is evidenced by the recent completion of our $318 million common equity offering, the closing on three of our asset divestitures resulting in approximately $430 million in debt reduction and our recent announcement regarding our plans for the divestiture of our Whiting Petroleum business. With the divestiture of Whiting and our continued cost control initiatives, we will have successfully completed all five of the strategic actions. In addition, we are also pleased with the progress we are making in improving the financial performance of our core business as our earnings from continuing operations are $0.43 per share higher for the first six months of 2003 compared to the same period in 2002." Earnings From Continuing Operations A summary of Alliant Energy's EPS from continuing operations for the second quarter is as follows: 2003 2002 Variance --------- ---------- ------------ Utility operations: Operating expenses ($.17) Electric margins .16 Effective income tax rate (.03) Other (.01) ------------ Total utility operations $ .25 $ .30 (.05) Non-regulated operations business units: International .02 (.17) .19 McLeodUSA/PHONES valuation charges - (.06) .06 Investments ($.05 Mexico valuation adjustment in '02) .01 (.03) .04 Integrated Services - (.01) .01 Energy Technologies - - - Non-regulated Generation (.01) (.01) - Other (primarily A&G/interest expense) (.04) - (.04) --------- ---------- ------------ Total non-regulated operations (.02) (.28) .26 Parent company and other (.10) (.08) (.02) --------- ---------- ------------ Earnings per share from continuing operations $ 0.13 ($0.06) $ 0.19 ========= ========== ============ The higher utility operating expenses were due to increases in the amortization of deferred costs that are now being recovered in rates, the impact of a planned refueling outage at the Kewaunee Nuclear Power Plant in the second quarter of 2003 and higher depreciation, uncollectible customer accounts, employee benefits and insurance expenses. These items were partially offset by lower property tax and fossil generation expenses. The higher electric margins resulted from the impact of various rate increases implemented in the second half of 2002 and the first six months of 2003, including increased revenues to recover a significant portion of the cost increases previously discussed, and increased sales resulting from continued modest retail customer growth. The electric margin comparison was negatively impacted by milder weather conditions in the second quarter of 2003 compared to the same period in 2002. Alliant Energy - Second Quarter 2003 Earnings Page 3 of 6 July 28, 2003 "Our customers demand safe, reliable and environmentally sound utility service and we are committed to meeting that demand," said Davis. "Continued investments in our utility infrastructure are a key component in delivering on that commitment. These investments, as well as our improved financial profile, depend on receiving appropriate rate relief. Recent rate decisions have been fair and balanced and support our commitment to our customers." The significant increase of $0.19 per share from Alliant Energy's International business unit was driven by a $0.15 per share increase from the company's Brazilian investments (losses of $1 million and $15 million in the second quarter of 2003 and 2002, respectively). The second quarter results included foreign currency transaction gains (losses) of $0.03 and ($0.04) in 2003 and 2002, respectively, related to $39 million in debt at one of the Brazilian operating companies. A 4.3% increase in electricity sales in the second quarter of 2003, compared to the same period in 2002, and rate increases implemented at four of the Brazilian operating companies in the first half of 2003 also contributed to the significant improvement in results. The 2002 second quarter results also included a charge of $0.03 per share related to the recovery in Brazil of the impacts of rationing and other prior costs. These items were partially offset by higher interest expense at the Brazilian companies. Earnings from Alliant Energy's New Zealand and China investments were up $0.03 and $0.01 per share, respectively. "Our past challenges in Brazil are well known," said Davis. "However, energy demand is increasing, several rate increases have been approved and the macro-economic factors are turning favorable. We are encouraged by the improved financial performance in the second quarter. Our position regarding this investment remains unchanged. We have no intentions to invest additional capital in this market and if we don't see sustained improvement in financial performance in the second half of the year, we will re-evaluate our commitment to the Brazil market at that time." 2003 Earnings Guidance Alliant Energy's 2003 earnings guidance for earnings from continuing operations remains a range of $1.45-1.65 per share, which includes guidance for its domestic utility operations of $1.75-1.95 per share. This guidance does not include any potential asset valuation charges that Alliant Energy may incur in 2003, the impact of certain non-cash SFAS 133 valuation adjustments or the impact of any cumulative effects of changes in accounting principles. Alliant Energy is currently unable to provide meaningful earnings guidance for its discontinued operations given uncertainties related to the timing of, and value realized from, the closing of its Whiting divestiture, the transaction structures Alliant Energy utilizes to exit its Whiting business and various other accounting adjustments or other charges and/or income related to the proposed asset sales. The guidance also assumes the Whiting business continues to be classified as held for sale until sold, and no additional businesses included in the guidance for continuing operations are classified as held for sale in 2003. Drivers for Alliant Energy's earnings from continuing operations estimates include, but are not limited to: o Normal weather conditions in its domestic and international utility service territories o Economic development and sales growth in its utility service territories o Continuing cost controls and operational efficiencies o Ability of its domestic and international utility subsidiaries to recover their operating costs, and to earn a reasonable rate of return, in current and future rate proceedings as well as their ability to recover purchased power and fuel costs o Improved results of its Brazil investments, no material adverse changes in the rates allowed by the Brazilian regulators or from the expected utility sector reform currently being considered by Brazil regulators and the ability of our Brazil investments to refinance certain debt outstanding o Improved results from its other non-regulated businesses Alliant Energy - Second Quarter 2003 Earnings Page 4 of 6 July 28, 2003 o No material permanent declines in the fair market value of, or expected cash flows from, Alliant Energy's investments o Other stable business conditions, including an improving economy o Continued access to the capital markets o The amount of premiums incurred in connection with our planned debt reduction o Ability of Alliant Energy to successfully execute its proposed asset divestitures at values and timelines that are consistent with the assumptions underlying its earnings guidance Quarterly Earnings Conference Call A conference call to review the second quarter 2003 earnings and other financial issues is scheduled for Monday, July 28 at 10:00 a.m. central time.
