Forward-looking statements

This material includes forward-looking statements. These statements can be identified because they include words such as “expects,” “expected,” “plans,” “will,” “outlook,” “estimate,” “target,” “may,” “believe,” “goal,” “potential,” “projected,” “projection,” or other words or expressions of similar import. Similarly, statements that describe future plans or strategies, our environmental stewardship goals, future emissions reductions, transitioning our energy resources, planned resource additions, and scenarios and scenario results are forward-looking statements. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in, or implied by, the statements. Actual results could be materially affected by the following factors, among others: the ability to obtain regulatory approval for construction projects with acceptable conditions; federal and state regulatory or governmental actions, including the impact of legislation, regulatory agency orders and executive orders, and changes in public policy, including changes impacting renewable tax credits; the ability to complete construction of generation and energy storage projects by planned in-service dates and within the cost targets set by regulators due to cost increases of and access to materials, equipment and commodities, which could result from tariffs, duties or other assessments, inflation, labor issues or supply shortages, the ability to successfully resolve warranty issues or contract disputes; the ability to obtain adequate generator interconnection agreements to connect new generation projects to the Midcontinent Independent System Operator, Inc. (MISO) in a timely manner; the ability of potential large load growth customers to timely construct new facilities, as well as the resulting higher system load demand by expected levels and timeframes; the ability to achieve the expected level of tax benefits based on tax guidelines, timely in-service dates, compliance with prevailing wage and apprenticeship requirements, project costs and the level of electricity output generated by qualifying generating facilities, and the ability to efficiently utilize the renewable generation and energy storage project tax benefits to achieve IPL’s authorized rate of return and for the benefit of IPL’s and WPL’s customers; the ability to utilize tax credits generated to date, and those that may be generated in the future, before they expire, as well as the ability to transfer tax credits that may be generated in the future at adequate pricing; the ability and cost to provide sufficient generation and the availability of sufficient transmission capacity for potential load growth, including significant new commercial or industrial customers, such as data centers; the timely development of technologies, innovations and advancements to provide cost effective alternatives to traditional energy sources; the future development of technologies related to electrification, and the ability to reliably store and manage electricity; changes to the MISO resource adequacy process establishing capacity planning reserve margin and capacity accreditation requirements that may impact how and when new and existing generating facilities may be accredited with energy capacity; economic conditions and the impact of business or facility closures in Alliant Energy’s service territory; changes in demand for energy in Alliant Energy’s service territory; continued access to the capital markets on competitive terms and rates, and the actions of credit rating agencies; inflation and higher interest rates; the impacts of changes in the tax code, including tax rates, minimum tax rates, adjustments made to deferred tax assets and liabilities, and changes impacting the availability of and ability to transfer renewable tax credits; issues associated with environmental remediation and environmental compliance, including compliance with all current environmental and emissions laws, regulations and permits and future changes in environmental laws and regulations, including the Coal Combustion Residuals Rule, Cross-State Air Pollution Rule and federal, state or local regulations for emissions reductions, including greenhouse gases (GHG), from new and existing fossil-fueled electric generating units under the Clean Air Act, and litigation associated with environmental requirements; increased pressure from customers, investors and other stakeholders to more rapidly reduce GHG emissions; the ability to defend against environmental claims brought by state and federal agencies, such as the U.S. Environmental Protection Agency and state natural resources agencies, or third parties, such as the Sierra Club, and the impact on operating expenses of defending and resolving such claims; the direct or indirect effects resulting from breakdown or failure of equipment in the operation of electric and gas distribution systems, such as mechanical problems, disruptions in telecommunications, technological problems, and explosions or fires, and compliance with electric and gas transmission and distribution safety regulations impacts that excessive heat, excessive cold, storms, wildfires or natural disasters may have on operations and construction activities; changes in technology that alter the channels through which customers buy or utilize Alliant Energy’s products and services; current or future litigation, regulatory investigations, proceedings or inquiries; reputational damage from negative publicity, protests, fines, penalties and other negative consequences resulting in regulatory and/or legal actions; employee workforce factors, including the ability to hire and retain employees with specialized skills, impacts from employee retirements, changes in key executives, ability to create desired corporate culture, collective bargaining agreements and negotiations, work stoppages or restructurings; changes to the creditworthiness of, or performance of obligations by, counterparties with which Alliant Energy has contractual arrangements, including large load growth customers, participants in the energy markets and fuel suppliers and transporters; the direct or indirect effects resulting from pandemics; and other risk factors discussed in Alliant Energy’s most recent Annual Form 10-K report to the U.S. Securities and Exchange Commission (SEC), including the section therein titled “Risk Factors,” and its other filings with the SEC.
