Slide 1 — Alliant Energy Corporation Stock Split Q&A

Alliant Energy Corporation Stock Split Q&A What is a two-for-one stock split? The Alliant Energy Corporation Board of Directors declared a two-for-one stock split, payable on May 19, 2016, for shareowners of record on May 4, 2016. In a two-for-one stock split, each shareowner receives one additional share for each share that he or she holds at the close of business on May 4th, known as the record date. After the two-for-one split, the number of issued shares is doubled, and the price of each share will be roughly one-half of the pre-split share-price meaning the total value of the holdings immediately after the split will be the same as before the split. Each shareowner’s investment value remains the same until the stock price moves up or down. For example, a shareowner who owns 100 shares of Alliant Energy Corporation common stock at a market price of $80 as of the record date has a total value of $8,000. After the split, the shareowner would own 200 shares of Alliant Energy Corporation common stock valued at $40 per share for a total investment of $8,000. What do I need to do if I own shares of stock? No action is required on your part. Wells Fargo Shareowner Services, our transfer agent, or your broker will automatically adjust your share balances on the payment date. Why did the Alliant Energy Corporation Board of Directors authorize a stock split? The stock split reflects the Board of Directors’ continued confidence in the long-term financial performance of Alliant Energy Corporation. The split will also cause us to trade more in line with the stock price of our industry peers and could be more attractive to new retail investors and expand our shareowner base. What is the record date? The record date is May 4, 2016. If you are a shareowner as of the market close on the record date, you are entitled to receive the additional shares if you continue to own your shares through the payment date. What is the payment date? The payment date for the additional shares is May 19, 2016. When will the stock begin trading at its post-stock split price on the New York Stock Exchange (NYSE)? When the market opens on May 20, 2016, the first trading day after the payment date, shares of Alliant Energy Corporation will begin trading on the NYSE at the split-adjusted price.

Slide 2 — Yes, Alliant Energy Corporation’s stock has split. Alliant Energy Corporation was formed by a merger in

Yes, Alliant Energy Corporation’s stock has split. Alliant Energy Corporation was formed by a merger in 1998 and its predecessor companies issued stock splits over the history of their existence, each impacting the basis of today’s LNT stock. Predecessor company Wisconsin Power & Light completed two 2-for-1 stock splits prior to merger. The first split was on May 16, 1962 and the second was on September 23, 1988. Iowa Electric Light & Power completed a 2-for-1 stock split on June 3, 1963 and Iowa Southern Utilities completed 2-for-1 stock splits on July 19, 1963 and June 13, 1986. Did the shareowners vote to approve the stock split? Shareowner approval is not required. Under Wisconsin law, our Board of Directors is authorized to approve an amendment to our articles of incorporation, without shareowner action, to change each share into a greater number of whole shares. Accordingly, only the approval of the Board of Directors was required. I hold shares in a brokerage account. Will my additional stock split shares be credited to that account as well? If you hold shares in a brokerage account, the additional shares relative to your brokerage account balance will automatically be deposited to your brokerage account. Please contact your broker with any questions you may have. Can I trade shares between the Record Date and the Payment Date? Yes. Alliant Energy Corporation shares will continue to trade at the higher pre-split price. If you sell your shares at the pre-split price during this period, you are not entitled to the split shares you would have received by virtue of being a holder on the Record Date because you have already received full value for the shares you sold. In essence, you have transferred the right to receive the split shares to the buyer. Conversely, if you buy stock at the pre-split price during this period, you are entitled to receive the stock split shares because you purchased the right to do so. From April 20, 2016 through May 19, 2016, the Company's common stock will trade only at the pre-split price. The Company's common stock will trade at the post-split price on May 20, 2016, the day after the stock split share distribution. What if I make optional cash purchases under the Shareowner Direct Plan between the stock split record date and the payment date? There will be one optional cash purchase between the stock split record date and the payment date (May 16, 2016). Shares acquired through optional cash purchases will be handled in the same manner as described in the previous answer. What happens if I sold some of my shares before the record date? If you sold your shares before the record date, you are not entitled to receive the additional shares.

Slide 3 — How will my additional shares of Alliant Energy Corporation stock be issued?

How will my additional shares of Alliant Energy Corporation stock be issued? The additional shares you will receive as a result of the stock split will be distributed in book-entry form through the Direct Registration System (DRS) or distributed to your account in the Alliant Energy Shareowner Direct Plan if your shares are held in the plan. This means that you will have full ownership of your additional shares without the responsibility of holding actual stock certificates. What is “book-entry”? Book-entry form of registered ownership allows you to own shares electronically without having paper stock certificates in your possession. You are the record owner and enjoy the same shareowner benefits you would with certificated shares. What are the benefits of book-entry shares? Book-entry ownership eliminates some of the problems associated with paper certificates such as storage and safety of securities. Book-entry shares also eliminate the requirement for physical movement of stock certificates at the time of sale or transfer of ownership. Are there any fees associated with holding shares in book-entry form? There are no fees to the shareowner for holding shares in book-entry form. How can I confirm the number of additional shares that were issued to me as a result of the stock split? Within approximately two weeks of the payment date, a statement will be mailed to shareowners of record as your confirmation of the number of additional shares you received as a result of the stock split relative to your Wells Fargo share account. Keep it with your existing stock certificates and other important documents as a record of your ownership. If you hold shares in a brokerage account, please contact your broker after the payment date to confirm the number of additional shares issued to you as a result of the stock split. If I hold Alliant Energy Corporation stock certificates now, what should I do with my stock certificates? Existing Alliant Energy Corporation stock certificates are still valid and will continue to represent the number of shares listed on the certificates, regardless of the stock split. Do not destroy them. However, we believe book-entry is the safest and most convenient way to hold your Alliant Energy Corporation shares. You can convert your shares held in certificate form into book-entry shares by mailing your certificates and a letter of instruction via registered or certified mail with return receipt requested, or some other form of traceable, insured mail to: Wells Fargo Shareowner Services, P.O. Box 64856, St. Paul, MN 55164-0856. For security purposes, please do not sign your certificates. Once the certificated shares are converted to book-entry form, you will receive a statement confirming your account balance. It is recommended you insure the mailing for 3 percent of the value of the certificated shares that you
