ALLIANT ENERGY ANNOUNCES SECOND QUARTER 2020 RESULTS

MADISON, Wis. - August 6, 2020 - 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:



	2020		2019
Utilities and Corporate Services		$0.48		$0.38
American Transmission Company (ATC) Holdings	0.04		0.03
Non-utility and Parent	0.02		(0.01		)
Alliant Energy Consolidated		$0.54		$0.40

“Our purpose-driven strategy has once again delivered solid results. We recently released our new Corporate Responsibility Report highlighting dozens of stories of how we are living our values as we deliver on our environmental goals and serving the social needs of the communities we call home, which have been even more important during the first half of this year,” said John Larsen, Alliant Energy Chairman, President and CEO. “With continued focus on cost management to offset COVID-19 impacts on sales, we are affirming our 2020 earnings guidance range.”

Utilities and Corporate Services - Alliant Energy’s Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.48 per share of GAAP EPS in the second quarter of 2020, which was $0.10 per share higher than the second quarter of 2019. The primary drivers of higher EPS were higher earnings resulting from IPL’s and WPL’s increasing rate base, as well as favorable temperature impacts on electric sales for the quarter. These items were partially offset by higher depreciation expense and timing of income taxes. Alliant Energy’s temperature-normalized retail electric sales in the second quarter decreased for commercial and industrial customers, partially offset by an increase for residential customers mainly due to the COVID-19 pandemic. The resulting modest decrease in retail electric sales was primarily mitigated by cost reduction measures.

Non-utility and Parent - Alliant Energy’s Non-utility and Parent operations generated $0.02 per share of GAAP EPS in the second quarter of 2020, which was a $0.03 per share earnings increase compared to the second quarter of 2019. The higher EPS was primarily driven by the timing of income taxes.

Details regarding GAAP EPS variances between the second quarters of 2020 and 2019 for Alliant Energy are as follows:



	Variance
Higher revenue requirements primarily due to increasing rate base		$0.17
Estimated temperature impact on retail electric and gas sales	0.04
Higher depreciation expense	(0.03		)
Timing of income taxes	(0.01		)
Other	(0.03		)
Total		$0.14

Higher revenue requirements primarily due to increasing rate base - In March 2019, Interstate Power and Light Company (IPL) filed a request with the Iowa Utilities Board (IUB) to increase annual rates for its Iowa retail electric and gas customers, based on a 2020 forward-looking test period. An interim retail electric rate increase was implemented effective April 2019. The IUB approved a settlement agreement to increase retail gas rates, which was implemented on January 10, 2020. The IUB approved a settlement agreement to increase retail electric rates, which was implemented on February 26, 2020. IPL recognized $0.12 per share increase in the second quarter of 2020 due to the higher revenue requirements from increasing rate base. Increasing rate base at IPL is primarily attributed to its new wind generation projects. These investments have increased depreciation expense and reduced fuel costs.

In December 2018, Wisconsin Power and Light Company (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. Under the settlement, WPL’s retail electric and gas base rates will not change from 2018 levels through the end of 2020. The retail electric revenue requirement increase, resulting from increasing investments in rate base, was offset by the federal Tax Cuts and Jobs Act of 2017 benefits and lower fuel-related costs. WPL recognized $0.05 per share in the second quarter of 2020 due to the retail electric and gas revenue requirement increase primarily due to increasing rate base. Increasing rate base at WPL is primarily attributed to its West Riverside expansion project. This investment has increased depreciation expense and reduced fuel costs.

Estimated temperature impact on retail electric and gas sales - Alliant Energy’s retail electric and gas sales increased in the second quarter of 2020 due to impacts of temperatures on customer demand. The estimated temperature impacts on retail electric and gas sales was a $0.02 per share increase in the second quarter of 2020, and was a $0.02 per share decrease in the second quarter of 2019.

Timing of income taxes - 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 will be resolved by the end of the year.

Use of Non-GAAP Financial Measures

To provide investors with additional information regarding Alliant Energy’s financial results, this press release includes reference to certain non-GAAP financial measures. These measures include income and EPS for the six months ended June 30, 2020 excluding a credit loss charge on guarantees for an affiliate of Whiting Petroleum. Alliant Energy believes this non-GAAP financial measure is useful to investors because it provides an alternate measure to better understand and compare across periods the operating performance of Alliant Energy without the distortion of items that management believes are not normally associated with ongoing operations, and also provides 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. Alliant Energy’s management also uses income, as adjusted, to determine performance-based compensation.

In addition, Alliant Energy included in this press release IPL; WPL; Corporate Services; Utilities and Corporate Services; ATC Holdings; and Non-utility and Parent EPS for the three and six months ended June 30, 2020 and 2019. 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 2020 Form 10-Q.

The tax impact adjustment represents the impact of the tax effect of the pre-tax non-GAAP adjustment excluded from non-GAAP net income. The tax impact of the non-GAAP adjustment is calculated based on the estimated consolidated statutory tax rate.

Reconciliations of the non-GAAP financial measures included in this press release to the most directly comparable GAAP financial measures are included in the earnings summaries that follow.

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