Alliant Energy Announces Second Quarter 2019 Results

MADISON, Wis., Aug. 1, 2019 /PRNewswire/ -- Alliant Energy Corporation (NASDAQ: LNT) today announced U.S. generally accepted accounting principles (GAAP) consolidated unaudited earnings per share (EPS) for the three months ended June 30 as follows:


                                         2019 2018



      Utilities and Corporate Services  $0.38        $0.41


      American Transmission Company
       (ATC) Holdings                    0.03         0.03



     Non-utility and Parent           (0.01)      (0.01)



      Alliant Energy Consolidated       $0.40        $0.43

"Our results reflect that our continued investments in cleaner energy are delivering tangible benefits to our customers," said John Larsen, Alliant Energy Chairman, President and CEO. "With continued focus on cost management, and higher year-to-date sales due to temperatures, we are forecasting 2019 earnings toward the top half of our 2019 earnings guidance range."

Utilities and Corporate Services - Alliant Energy's Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.38 per share of GAAP EPS in the second quarter of 2019, which was $0.03 per share lower than the second quarter of 2018. The primary drivers of lower EPS were lower retail electric sales due to cooler temperatures in the second quarter 2019 compared to the same period last year, higher depreciation expense, and timing of income tax expense. These items were partially offset by higher margins due to Interstate Power and Light Company's (IPL's) and Wisconsin Power and Light Company's (WPL's) increasing rate base.

Details regarding GAAP EPS variances between the second quarters of 2019 and 2018 for Alliant Energy are as follows:

Higher revenue requirements primarily due to increasing rate base - In March 2019, IPL filed a request with the Iowa Utilities Board (IUB) to increase annual rates for its Iowa retail electric customers by $204 million, based on a 2020 forward-looking test period. IPL concurrently filed for interim retail electric rates based on 2018 historical data adjusted for certain known and measurable changes occurring in the first quarter of 2019. An interim retail electric rate increase of $90 million, on an annual basis, was implemented effective April 2019. Implementing interim rates does not require regulatory approval; however, interim rates are subject to refund pending the IUB's final rate review decision. IPL currently expects a final decision from the IUB in the fourth quarter of 2019 on the interim rate increase, as well as the remaining $114 million of final rates, which would be effective in the first quarter 2020. IPL recognized $0.12 per share of higher electric margins in the second quarter of 2019 due to the retail electric rate increases.

In December 2018, WPL received an order from the Public Service Commission of Wisconsin approving WPL's proposed settlement for its retail electric and gas rate review covering the 2019/2020 Test Period, effective January 1, 2019. Under the settlement, WPL's retail electric and gas base rates will not change from current levels through the end of 2020. The $61 million retail electric revenue requirement increase for 2019, resulting from increasing investments in rate base, was offset by lower fuel-related costs and federal tax reform refunds. WPL recognized $0.05 per share of higher electric margins from increasing investments in rate base in the second quarter of 2019.

Estimated temperature impact on retail electric and gas sales - The impact of cooler than normal temperatures in the second quarter of 2019 was estimated to be a $0.02 per share decrease in margins. By comparison, the impact of warmer than normal temperatures in the second quarter of 2018 was estimated to be a $0.06 per share increase in margins.

WPL's retail electric and gas rate settlement covering 2018 included an earnings sharing mechanism, whereby WPL deferred a portion of its earnings and will return that amount to its retail electric and gas customers since its annual regulatory return on common equity exceeded 10.25% during 2018. In the first half of 2018, Alliant Energy's temperature impact on retail electric and gas sales, net of WPL's earnings sharing mechanism, was estimated to be a $0.05 per share increase in margins. By comparison, the impact of colder than normal temperatures in the first half of 2019 was estimated to be a $0.03 per share increase in margins.

Timing of income tax expense - Tax expenses are recorded based on an estimated annual effective tax rate, which causes fluctuations in the amount of tax expense quarter-over-quarter. The timing variance is resolved by the end of the year.

Use of Non-GAAP Financial Measures

Alliant Energy included in this press release IPL; WPL; Corporate Services; Utilities and Corporate Services; ATC Holdings; and Non-utility and Parent EPS from continuing operations for the three and six months ended June 30, 2019 and 2018. Alliant Energy believes these non-GAAP financial measures are useful to investors because they facilitate an understanding of segment performance and trends, and provide additional information about Alliant Energy's operations on a basis consistent with the measures that management uses to manage its operations and evaluate its performance.

This press release references year-over-year variances in utility electric margins and utility gas margins. Utility electric margins and utility gas margins are non-GAAP financial measures that will be reported and reconciled to the most directly comparable GAAP measure, operating income, in our second quarter 2019 Form 10-Q.

Note: Unless otherwise noted, all "per share" references in this release refer to earnings per diluted share.
