The units will be settled in shares of common stock when he terminates service as a director, meaning he does not receive actual shares or cash now.

Alliant Energy Corporation is asking shareowners to vote at its virtual 2026 annual meeting on May 20, 2026, on electing four directors, approving executive pay on an advisory basis, and ratifying Deloitte & Touche LLP as auditor for 2026.
The proxy highlights a pay-for-performance design. 2025 GAAP EPS from continuing operations was $3.14, with adjusted EPS of $3.24, leading to a 130% payout of the annual incentive pool based on financial, customer, environmental and safety metrics. CEO Lisa Barton’s 2025 base salary was $1,139,500, with a long-term equity target equal to 460% of salary.
Long-term incentives are mostly performance-based shares tied to relative total shareholder return, net income growth, and renewable generation and storage build-out, plus time-vesting restricted stock units. The Board remains majority independent, uses majority voting in uncontested elections, and oversees risk through a formal enterprise risk management framework and specialized Board committees.
Alliant Energy Corp Schedule 13G/A amendment reports that The Vanguard Group holds 0 shares of Common Stock, representing 0% of the class.

Alliant Energy Corporation entered into a new equity distribution agreement that allows it to sell, from time to time, shares of common stock with an aggregate offering price of up to $1,000,000,000. Sales may be made through multiple banks acting as agents on the Nasdaq Global Select Market or directly to an agent acting as principal.

Net proceeds are intended for general corporate purposes, including debt repayment, working capital and construction or acquisition spending.
Alliant Energy Corporation has filed a prospectus supplement to offer up to $1,000,000,000 of common stock through an "at-the-market" distribution agreement running through December 31, 2029. Sales may occur through designated agents or via forward sale agreements with specified forward purchasers. The filing states proceeds will be received upon physical settlement of forward sales, while borrowed-share sales by forward sellers will not initially provide proceeds. The offering permits multiple sale methods, a 1.00% selling commission to agents, and various settlement options including physical, cash or net share settlement.
