(NYSE: LNT) today reported income (loss) and earnings per share (EPS) from continuing operations for the first quarter of 2003 of $14.6 million and $0.16, respectively, compared to ($7.8) million and ($0.09) for the same period in 2002. Alliant Energy's net income (loss) and EPS for the first quarter of 2003 were ($0.5) million and ($0.01), respectively, compared to $9.7 million and $0.11 for the same period in 2002. Additional details regarding Alliant Energy's first quarter unaudited earnings are as follows (net income in millions): Q1 2003 Q1 2002 ----------------------------------------------------- Earnings from continuing operations: Net Income EPS Net Income EPS ----------------------------------------------------- Utility $ 31.0 $ 0.34 $ 27.0 $ 0.30 Non-regulated (AER) (10.7) (0.12) (32.6) (0.36) Parent and other (5.7) (0.06) (2.2) (0.03) ----------------------------------------------------- Total earnings from continuing operations 14.6 0.16 (7.8) (0.09) Earnings from discontinued operations: * Operating results (increase largely due to higher oil/gas prices) 4.0 0.04 (2.4) (0.02) Non-cash valuation and other accounting adjustments: Southern Hydro SFAS 133 income 6.8 0.07 19.9 0.22 Discontinuing depreciation, depletion and amortization of assets held for sale 7.9 0.09 - - Valuation adjustments and selling costs (27.8) (0.30) - - ----------------------------------------------------- Total earnings from discontinued operations (9.1) (0.10) 17.5 0.20 Cumulative effect of changes in accounting principles (6.0) (0.07) - - ----------------------------------------------------- Net income/(loss) $ (0.5) $ (0.01) $ 9.7 $ 0.11 ===================================================== * Alliant Energy classified its oil and gas, affordable housing and Australian businesses as assets held for sale and discontinued operations in the fourth quarter of 2002 and classified its SmartEnergy business as an asset held for sale and discontinued operations in the first quarter of 2003. The higher utility earnings from continuing operations were largely due to increased gas and electric margins, which were partially offset by higher operating expenses. The significant improvement in non-regulated results from continuing operations was primarily due to $0.26 per share of asset valuation charges recorded in the first quarter of 2002. Improvements in the results of the underlying operations of Alliant Energy's non-regulated businesses were largely offset by higher interest expense. Alliant Energy recorded after-tax valuation adjustments of $26 million in the first quarter of 2003 to reflect updated estimates of the market value, less selling costs, of the $1 billion of assets it has classified as assets held for sale. Alliant Energy anticipates closing on the sale of its Australian business in late April and expects to realize an after-tax gain significantly higher than the valuation adjustments recorded in the first quarter related to Alliant Energy's other assets held for sale. As a result, the estimated proceeds available to Alliant Energy for debt reduction from planned asset divestitures remains within a range of $800 million to $1 billion. Alliant Energy - First Quarter 2003 Earnings Page 2 of 6 April 28, 2003 "We are very pleased with the significant progress we have made in the execution of the plans we announced in November 2002 to strengthen our financial profile and to narrow our strategic focus," said Erroll B. Davis, Jr., chairman, president and CEO of Alliant Energy. "Our focus will remain on the continued successful execution of these strategic actions. Given the significant rate relief we received in the second quarter of 2003, we are affirming our 2003 earnings guidance for earnings from continuing operations." Earnings From Continuing Operations A summary of Alliant Energy's EPS from continuing operations for the first quarter is as follows: 2003 * 2002 Variance ------------- ------------ ------------- Utility operations: Gas margins $ .15 Electric margins .05 Operating expenses (.16) ------------- Total utility operations $ .34 $ .30 .04 Non-regulated operations business units: McLeodUSA valuation adjustment - (.14) .14 Integrated Services .02 (.06) .08 Energy Technologies - (.04) .04 Investments .01 .01 - International (.09) (.09) - Non-regulated Generation (.02) (.01) (.01) Other (primarily interest expense/income) (.04) (.03) (.01) ------------- ------------ ------------- Total non-regulated operations (.12) (.36) .24 Parent company and other (.06) (.03) (.03) ------------- ------------ ------------- Earnings per share from continuing operations $ 0.16 $ (0.09) $ 0.25 ============= ============ ============= * 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. The higher gas and electric margins resulted from the impact of various rate increases implemented in 2002 and higher sales volumes largely due to more favorable weather conditions in the first quarter of 2003 compared to the same period in 2002 as well as continued modest retail customer growth. Alliant Energy continued to see modest improvements in the economy in its utility service territories as evidenced by a 2% increase in electric sales to industrial customers in the first quarter of 2003 compared to the same period in 2002. The positive impacts on electric margin noted above were partially offset by higher purchased power and fuel costs. The increase in utility operating expenses was primarily due to increased depreciation and amortization, fossil and nuclear generation and employee benefits expenses. A significant portion of these cost increases are being recovered as a result of the rate increases implemented in 2002. Alliant Energy also received two additional rate orders in April 2003. "Our domestic utility operations continue as the foundation of Alliant Energy," said Davis. "They continue to provide safe, reliable and environmentally sound utility service to our customers and we are pleased with the continued progress we are making in our various utility rate cases, which is a key component in improving our financial profile." Alliant Energy - First Quarter 2003 Earnings Page 3 of 6 April 28, 2003 In addition to the $0.14 per share asset valuation charge recorded in the first quarter of 2002 related to Alliant Energy's investment in McLeodUSA, Alliant Energy also recorded asset valuation charges of $0.06 and $0.04 per share in the first quarter of 2002 within its Integrated Services and Energy Technologies business units. Cumulative Effect of Changes in Accounting Principles Alliant Energy recorded charges of $0.05 and $0.02 per share in the first quarter of 2003 for the cumulative effect of changes in accounting principles related to the adoption on Jan. 1, 2003 of SFAS 143 (Accounting for Asset Retirement Obligations) and EITF Issue 02-3 (Issues Related to Accounting for Contracts Involved in Energy Trading and Risk Management Activities) within its oil and gas (which is being reported as discontinued operations) and Integrated Services businesses, respectively. 2003 Earnings Guidance Alliant Energy's 2003 earnings guidance for earnings from continuing operations is 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 the closing of each asset divestiture, the values realized from each asset divestiture, the transaction structures Alliant Energy utilizes to exit these businesses, various other accounting adjustments or other charges and/or income related to the proposed asset sales and earnings volatility related to the non-cash valuation adjustments associated with the electricity derivatives outstanding at Southern Hydro. The guidance also assumes the four businesses reported as discontinued operations at March 31, 2003, continue 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 and no material adverse changes in the rates allowed by the Brazilian regulators o Improved results from its other non-regulated businesses 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 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 Alliant Energy - First Quarter 2003 Earnings Page 4 of 6 April 28, 2003 Quarterly Earnings Conference Call A conference call to review the first quarter 2003 earnings and other financial issues is scheduled for Monday, April 28 at 10:00 a.m. central time.
