ALLIANT ENERGY CORP director Stephanie Cox received an award of 547.1960 Deferred Common Stock Units on April 10, 2026. The units are linked to a reference price of $73.1000 per unit and are structured as derivative securities tied to the company’s common stock.
Each deferred unit corresponds to 1 share of common stock, so the award relates to 547.1960 underlying shares. After this grant, Cox directly holds a total of 17,253.4510 deferred units. According to the terms, these units will be settled in shares of common stock when her service as a director ends.
The reported holdings also reflect adjustments for accrued dividends, which were credited through a dividend reinvestment transaction that is exempt from Section 16 under Rule 16a-11. The filing shows no open‑market buying or selling, only this grant/award acquisition of deferred units.

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. The filing explains an internal realignment effective January 12, 2026, that disaggregated certain Vanguard subsidiaries for reporting. The amendment is signed by Ashley Grim on 03/26/2026.
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.
The company may also use forward sale arrangements, where forward purchasers borrow and sell shares now and Alliant Energy receives cash later upon physical settlement of each forward confirmation. 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.
