ALLIANT ENERGY ANNOUNCES THIRD QUARTER 2019 RESULTS AND INCREASED ANNUAL COMMON STOCK DIVIDEND TARGET FOR 2020

Updates 2019 earnings guidance and provides 2020 earnings guidance and forecasted 2019 - 2023 capital expenditures

MADISON, Wis. - November 6, 2019 - Alliant Energy Corporation (NASDAQ: LNT) today announced U.S. generally accepted accounting principles (GAAP) and non-GAAP consolidated unaudited earnings per share (EPS) for the three months ended September 30 as follows:



	GAAP EPS						Non-GAAP EPS
	2019			2018			2019			2018
Utilities and Corporate Services		$0.92			$0.88			$0.92			$0.86
American Transmission Company (ATC) Holdings	0.03			0.03			0.03			0.03
Non-utility and Parent	(0.01		)	(0.04		)	(0.01		)	(0.04		)
Alliant Energy Consolidated		$0.94			$0.87			$0.94			$0.85

“As we advance our commitment to cleaner energy and affordable customer options, we are investing in renewable energy and distribution system enhancements,” said John Larsen, Alliant Energy Chairman, President and CEO. “We raised our 2019 earnings guidance to a range of $2.27 to $2.33 per share, largely due to the benefits of weather during the first nine months of this year. I am also pleased to share that our Board of Directors has approved a 7% increase to our annual common stock dividend target, raising it to $1.52 per share for 2020.”

Utilities and Corporate Services - Alliant Energy’s Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.92 per share of GAAP EPS in the third quarter of 2019, which was $0.04 per share higher than the third quarter of 2018. The primary drivers of higher EPS were higher earnings due to Interstate Power and Light Company’s (IPL’s) and Wisconsin Power and Light Company’s (WPL’s) increasing rate base and timing of income tax expense. These items were partially offset by higher depreciation expense and tax adjustments.

Non-utility and Parent - Alliant Energy’s Non-utility and Parent operations generated ($0.01) per share of GAAP EPS in the third quarter of 2019, which was a $0.03 per share earnings increase compared to the third quarter of 2018. The primary driver of higher EPS was tax adjustments and timing of income tax expense.

Earnings Adjustments - Non-GAAP EPS for the three and nine months ended September 30, 2018 excludes earnings of $0.02 per share related to tax return adjustments due to Federal Tax Reform. Non-GAAP adjustments, which relate to material charges or income that are not normally associated with ongoing operations, are provided as a supplement to results reported in accordance with GAAP.

Temperature Impacts to Non-GAAP EPS - The estimated year-to-date impact of temperatures on EPS compared to normal temperatures, is a $0.05 per share gain in 2019. The midpoint of the temperature normalized non-GAAP EPS guidance for the full year 2019 is $2.25.

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



	Q3 2019		Q3 2018		Variance
Higher revenue requirements primarily due to increasing rate base						$0.14
Higher depreciation expense					(0.05		)
Timing of income tax expense					0.04
Tax return adjustments due to Federal Tax Reform		$—		$0.02	(0.02		)
Equity dilution					(0.02		)
Higher interest expense					(0.02		)
Estimated temperature impact on retail electric and gas sales	0.02		0.02		—
Total						$0.07

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. In October 2019, IPL filed a partial settlement agreement with the IUB to increase annual rates for its Iowa retail electric customers by $127 million. As part of this agreement, IPL would refund $8 million of 2019 interim rates in 2020. The settlement agreement is pending the IUB’s final rate review decision. IPL recognized $0.09 per share of higher electric margins in the third quarter of 2019 due to the retail electric rate increase, including a reduction of $8 million as a result of the interim refund agreed to as part of the settlement.

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 third quarter of 2019.

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 positive year-over-year variance in third quarter offsets the negative year-over-year variance in the second quarter of 2019.

2019 Earnings Guidance

Alliant Energy is updating its EPS guidance for 2019 as follows. The midpoint of the 2019 EPS guidance was increased by $0.06 per share primarily due to higher earnings from temperature impacts on retail electric and gas sales during the first nine months of 2019.

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 three and nine months ended September 30, 2018 excluding the tax return adjustments due to Federal Tax Reform. 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 nine months ended September 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 third quarter 2019 Form 10-Q.

This press release also includes temperature-normalized non-GAAP EPS guidance for the year ended December 31, 2019. Alliant Energy believes this non-GAAP guidance measure is useful to investors because the measure facilitates period-to-period comparison of Alliant Energy’s operating performance and provides investors with information on a basis consistent with measures that management uses to assess Alliant Energy’s earnings growth 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, and in the case of temperature normalized non-GAAP EPS guidance, in the press release above.

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