Second quarter GAAP earnings per share was $0.63 in 2022 compared to $0.57 in 2021
With strong year-to-date results, currently tracking toward the upper half of 2022 earnings guidance range of $2.67 to $2.81 per share

MADISON, Wis., Aug. 04, 2022 (GLOBE NEWSWIRE) -- 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:

	GAAP EPS
	2022			2021
Utilities and Corporate Services	$	0.61		$	0.51
American Transmission Company (ATC) Holdings		0.03			0.03
Non-utility and Parent		(0.01	)		0.03
Alliant Energy Consolidated	$	0.63		$	0.57

"For the second year in a row, we are tracking toward the upper half of our 2022 earnings guidance fueled by our strong first-half results," said John Larsen, Alliant Energy Chair, President and CEO. "And we are excited to be putting the first project of our 1,100 megawatts of announced Wisconsin solar into service in the coming weeks, an important milestone as we advance our Clean Energy Blueprint."

Utilities and Corporate Services - Alliant Energy's Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.61 per share of GAAP EPS in the second quarter of 2022, which was $0.10 per share higher than the second quarter of 2021. The primary drivers of higher EPS were higher allowance for funds used during construction (AFUDC), timing of income tax expense and higher temperature-normalized sales. These items were partially offset by higher interest expense.

Non-utility and Parent - Alliant Energy's Non-utility and Parent operations generated ($0.01) per share of GAAP EPS in the second quarter of 2022, which was a $0.04 per share earnings decrease compared to the second quarter of 2021. The lower EPS was primarily driven by the timing of income taxes.

Details regarding GAAP EPS variances between the second quarters of 2022 and 2021 for Alliant Energy are as follows:

	Variance
Higher allowance for funds used during construction	$	0.02
Timing of income tax expense		0.02
Higher interest expense		(0.03	)
Other (primarily higher temperature-normalized sales in 2022)		0.05
Total	$	0.06

Higher allowance for funds used during construction (AFUDC) - AFUDC was higher in the second quarter of 2022 compared to the same period in 2021 primarily due to increased construction work in progress balances related to WPL's solar generation.

Timing of income tax expense - Income tax expense is recorded each quarter based on an estimated annual effective tax rate and the proportion of full year earnings generated each quarter, which causes fluctuations in the amount of tax expense quarter-over-quarter. The timing variance is expected to be reversed by the end of the year.

Higher interest expense - Total long-term debt increased due to additional financings since June 30, 2021 largely to fund capital expenditures including the solar expansion program in Wisconsin. In addition to higher long-term debt balances, increases to the interest rates charged to short-term debt contributed to higher interest expense in the second quarter of 2022 versus the same period in 2021.

2022 Earnings Guidance

Alliant Energy's consolidated guidance of $2.67 to $2.81 earnings per share for 2022 remains unchanged. Drivers for Alliant Energy's 2022 earnings guidance include, but are not limited to:

Ability of IPL and WPL to earn their authorized rates of return
Stable economy and resulting implications on utility sales
Normal temperatures in its utility service territories
Execution of cost controls
Execution of capital expenditure and financing plans
Consolidated effective tax rate of 3%

The 2022 earnings guidance does not include the impacts of any material non-cash valuation adjustments, regulatory-related charges or credits, reorganizations or restructurings, future changes in laws including corporate tax reform in Iowa, regulations or regulatory policies, adjustments made to deferred tax assets and liabilities from valuation allowances, changes in credit loss liabilities related to guarantees, pending lawsuits and disputes, settlement charges related to pension and other postretirement benefit plans, federal and state income tax audits and other Internal Revenue Service proceedings, or changes in GAAP and tax methods of accounting that may impact the reported results of Alliant Energy.
