"The second quarter results reflect higher than expected earnings due to warmer temperatures," said Patricia Kampling, Alliant Energy Chairman and CEO. "With the solid earnings to date, we are reaffirming 2018 earnings per share guidance."

Utilities and Corporate Services - Alliant Energy's Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.41 per share of GAAP EPS from continuing operations in the second quarter of 2018, which was $0.04 per share higher than the second quarter of 2017. The primary drivers of higher EPS were higher retail electric sales due to warmer temperatures in the second quarter of 2018 compared to the same period last year, and higher margins due to Interstate Power and Light Company's (IPL's) and Wisconsin Power and Light Company's (WPL's) increasing rate base. These items were partially offset by higher depreciation expense and the timing of operation and maintenance expenses.

Non-utility and Parent - Alliant Energy's Non-utility and Parent operations generated ($0.01) per share of GAAP EPS from continuing operations in the second quarter of 2018, which was a decline of $0.02 per share compared to the second quarter of 2017. The primary driver of lower EPS is the timing of income tax expense.

Details regarding GAAP EPS from continuing operations variances between the second quarters of 2018 and 2017 for Alliant Energy are as follows:

Estimated temperature impact on retail electric and gas sales - The impact of colder than normal temperatures in the first half, and warmer than normal temperatures in the second half, of the second quarter of 2018 was estimated to be a $0.06 per share increase in margins. By comparison, temperatures were considered normal in the second quarter of 2017, resulting in no impact to margins.

WPL's retail electric and gas rate settlement covering 2018 includes an earnings sharing mechanism whereby WPL must defer a portion of its earnings and return this amount to its retail electric and gas customers if its annual regulatory return on common equity exceeds 10.25% during 2018. As a result, a majority of the higher margins recognized at WPL as a result of the temperature impact on retail electric and gas sales in the first half of 2018 is currently expected to be given back to customers in the future. Year-to-date Alliant Energy's estimated temperature impact on retail electric and gas sales, net of the WPL earnings sharing mechanism, is estimated to be a $0.05 per share increase in margins.

Higher margins primarily from earning on increasing rate base - In April 2017, IPL filed a request with the IUB to increase annual rates for its Iowa retail electric customers. The request was based on a 2016 historical Test Year as adjusted for certain known and measurable changes occurring up to 12 months after the commencement of the proceeding. An interim retail electric rate increase of $102 million, on an annual basis, was implemented effective April 13, 2017. In February 2018, the IUB issued an order approving IPL's settlement reached in September 2017, for an annual electric base rate increase of $130 million, or approximately 9%. Final rates were effective May 1, 2018. IPL recognized $0.02 per share of higher electric margins in the second quarter of 2018 due to the interim and final retail electric rate increases.

In December 2016, WPL received an order from the Public Service Commission of Wisconsin authorizing WPL to implement a retail electric rate increase effective January 1, 2017 followed by a freeze of such rates through the end of 2018. To reflect the higher margins in 2018, primarily from earning on increasing rate base, the order lowered the amortization of amounts that WPL previously over-recovered from its customers for electric transmission cost recovery beginning in January 2018. WPL recognized $0.02 per share of higher electric margins in the second quarter of 2018 due to lower transmission cost recovery amortization.

Use of Non-GAAP Financial Measures

To provide investors with additional information, 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, 2018 and 2017. 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 are reported and reconciled to the most directly comparable GAAP measure, operating income, in our second quarter 2018 Form 10-Q.

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

                     day compared to a 65 degree
                     base.  Normal degree days are
                     calculated using a rolling
                     20-year average of historical
                     HDDs and CDDs.
