“In this uncertain environment of the global COVID-19 pandemic, our company continues to focus on providing the critical, reliable service our customers depend on, while emphasizing the health and welfare of our employees, customers and communities,” said John Larsen, Alliant Energy Chairman, President and CEO. “Based upon our forecasted impacts of COVID-19, and planned mitigation measures, we are reaffirming 2020 earnings guidance of $2.34 to $2.48 per share.

Utilities and Corporate Services - Alliant Energy’s Utilities and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.72 per share of GAAP EPS in the first quarter of 2020, which was $0.20 per share higher than the first quarter of 2019. 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. These items were partially offset by lower electric and gas sales volumes largely caused by warmer than normal temperatures in early 2020 and higher depreciation expense. First quarter 2020 EPS was not significantly impacted as a result of COVID-19.

Non-utility and Parent - Alliant Energy’s Non-utility and Parent operations generated ($0.05) per share of GAAP EPS in the first quarter of 2020, which was a ($0.03) per share earnings decrease compared to the first quarter of 2019. The primary driver of lower EPS was a $0.02 per share credit loss charge related to legacy guarantees associated with an affiliate of Whiting Petroleum Corporation (Whiting Petroleum).

Earnings Adjustments - Non-GAAP EPS for the three months ended March 31, 2020 excludes charges of $0.02 per share related to the credit loss charge described above for Alliant Energy’s Non-utility and Parent. 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.

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 and gas customers, 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 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 first quarter of 2020 due to the higher revenue requirements from increasing rate base. The positive variance recognized in the first quarter is larger than what is expected in subsequent quarters due to the timing of when new rates were implemented.

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. 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, were offset by Federal Tax Reform benefits and lower fuel-related costs. WPL’s Federal Tax Reform benefits are recognized based on an estimated annual effective tax rate, which also contributed to a higher positive variance in the first quarter than is expected in subsequent quarters. WPL recognized $0.07 per share due to the retail electric and gas revenue requirement increase primarily due to increasing rate base.

Timing of income tax expense - Recognition of excess deferred income taxes and production tax credits is based upon proportion of earnings distribution each quarter. The positive variance recognized in the first quarter is expected to continue through the first half of the year and reverse in the second half of 2020.

Credit loss charge on guarantees for an affiliate of Whiting Petroleum - A wholly-owned subsidiary of Alliant Energy continues to guarantee the partnership obligations of an affiliate of Whiting Petroleum under multiple general partnership agreements it maintains within the oil industry. The partnership obligations include the costs associated with the future abandonment of certain platforms off the coast of California and related onshore plant and equipment owned by the partnerships. Whiting Petroleum’s credit worthiness has deteriorated since December 31, 2019 as a result of significantly depressed oil and gas prices and general market conditions. Alliant Energy estimates an increase in the credit risk exposure related to the guarantees and has recognized a $0.02 per share charge for the additional expected credit loss in the first quarter of 2020.

2020 Earnings Guidance

Alliant Energy’s consolidated EPS guidance of $2.34 to $2.48 for 2020 remains unchanged. Drivers for Alliant Energy’s 2020 earnings guidance include, but are not limited to:
Ability of IPL and WPL to earn their authorized rates of return
Normal temperatures in its utility service territories
COVID-19 commercial and industrial sales decline offset by higher residential sales through June, with gradual sales improvement through end of year
Execution of cost controls
Execution of capital expenditure and financing plans
Consolidated effective tax rate of (12%)

The 2020 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, 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, 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.

Forward-Looking Statements

This press release includes forward-looking statements. These forward-looking statements can be identified by words such as “forecast,” “expect,” “guidance,” or other words of similar import. Similarly, statements that describe future financial performance or plans or strategies are forward-looking statements. Such forward looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, such statements. Actual results could be materially affected by the following factors, among others:

IPL’s and WPL’s ability to obtain adequate and timely rate relief to allow for, among other things, the recovery of and/or the return on costs, including fuel costs, operating costs, transmission costs, deferred expenditures, deferred tax assets, tax expense, capital expenditures, and remaining costs related to electric generating units (EGUs) that may be permanently closed and certain other retired assets, decreases in sales volumes, earning their authorized rates of return, and the payments to their parent of expected levels of dividends;
federal and state regulatory or governmental actions, including the impact of legislation, and regulatory agency orders;
the direct or indirect effects resulting from the COVID-19 pandemic on sales volumes, margins, operations, employees, contractors, vendors, the ability to complete construction projects, supply chains, customers’ inability to pay bills, suspension of disconnects and waiving of late fees applied to past due accounts, the market value of the assets that fund pension plans and the potential for additional funding requirements, the ability of counterparties to meet their obligations, compliance with regulatory requirements, the ability to implement regulatory plans, economic conditions and access to capital markets;
the impact of customer- and third party-owned generation, including alternative electric suppliers, in IPL’s and WPL’s service territories on system reliability, operating expenses and customers’ demand for electricity;
the impact of energy efficiency, franchise retention and customer disconnects on sales volumes and margins;
the impact that price changes may have on IPL’s and WPL’s customers’ demand for electric, gas and steam services and their ability to pay their bills;
the ability to utilize tax credits and net operating losses generated to date, and those that may be generated in the future, before they expire;
the direct or indirect effects resulting from terrorist incidents, including physical attacks and cyber attacks, or responses to such incidents;
the impact of penalties or third-party claims related to, or in connection with, a failure to maintain the security of personally identifiable information, including associated costs to notify affected persons and to mitigate their information security concerns;
any material post-closing payments related to any past asset divestitures, including the sale of Whiting Petroleum, which could result from, among other things, indemnification agreements, warranties, parental guarantees or litigation;
employee workforce factors, including changes in key executives, ability to hire and retain employees with specialized skills, ability to create desired corporate culture, collective bargaining agreements and negotiations, work stoppages or restructurings;
weather effects on results of utility operations;
issues associated with environmental remediation and environmental compliance, including compliance with all environmental and emissions permits, the Coal Combustion Residuals Rule, future changes in environmental laws and regulations, including federal, state or local regulations for carbon dioxide emissions reductions from new and existing fossil-fueled EGUs, and litigation associated with environmental requirements;
increased pressure from customers, investors and other stakeholders to more rapidly reduce carbon dioxide emissions;

continued access to the capital markets on competitive terms and rates, and the actions of credit rating agencies;
inflation and interest rates;
the ability to complete construction of wind and solar projects within the cost caps set by regulators and to meet all requirements to qualify for the full level of production tax credits and investment tax credits, respectively;
changes in the price of delivered natural gas, purchased electricity and coal due to shifts in supply and demand caused by market conditions and regulations;
disruptions in the supply and delivery of natural gas, purchased electricity and coal;

Without limitation, the expectations with respect to 2020 earnings guidance in this press release are forward-looking statements and are based in part on certain assumptions made by Alliant Energy, some of which are referred to in the forward-looking statements. Alliant Energy cannot provide any assurance that the assumptions referred to in the forward-looking statements or otherwise are accurate or will prove to be correct.

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 months ended March 31, 2020 excluding a new 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 months ended March 31, 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 first quarter 2020 Form 10-Q.

The tax impact adjustments represent the impact of the tax effect of the pre-tax non-GAAP adjustments excluded from non-GAAP net income. The tax impact of the non-GAAP adjustments 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.
