Forward-looking Statements

Alliant Energy 2018 Corporate Sustainability Report

This report includes forward-looking statements. These forward-looking statements can be identified as such because the statements include words such as “future,” “project,” “expected,” “plan,” “target,” “by 2030,” “by 2050,” or other words of similar import. Statements that describe future plans or strategies, emissions reductions, generation plans, capital expenditures, pipeline replacement plans and energy savings are also forward-looking statements. Such statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those currently anticipated, such as: our ability to obtain adequate and timely rate relief to allow for, among other things, earning a return on rate base additions and the recovery of costs; ability to obtain regulatory approval for wind projects with acceptable conditions, to acquire sufficient transmission-ready wind sites, to complete construction within the cost caps set by regulators and to meet all requirements to qualify for the full level of production tax credits; the impact of customer- and third party-owned generation on system reliability, operating expenses and customers’ demand for electricity; federal, state or local government actions; failure of equipment and technology to perform as expected; inability to access technological developments, including those related to wind turbines, solar generation, smart technology, energy storage, and other future technologies; plan design changes; changes in environmental laws and regulations; issues associated with environmental remediation and environmental compliance; current or future litigation, regulatory investigations, proceedings or inquiries; Alliant Energy’s continued access to capital markets; developments that adversely impact the ability to implement the strategic plan; political conditions in Alliant Energy’s service territories; and economic conditions in Alliant Energy’s service territory.

These factors, as well as factors identified in our filings with the Securities and Exchange Commission, should be considered when evaluating the forward-looking statements, and undue reliance should not be placed on such statements. The forward-looking statements included herein are made as of the date hereof, and Alliant Energy undertakes no obligation to update publicly such statements to reflect subsequent events or circumstances.

This report identifies certain priority issues. Priority issues are not necessarily material for financial reporting purposes.
