ALLIANT ENERGY CORP 8-K

What Happened Alliant Energy Corporation (LNT) reported (Item 5.02) that on January 5, 2026 its boards increased the number of directors to 11 and appointed Manu Asthana to the boards of Alliant Energy, Interstate Power and Light Company, and Wisconsin Power and Light Company, effective February 23, 2026. Mr. Asthana, age 52, served as President and CEO of PJM Interconnection from 2020 to 2025 and has held senior roles at utility companies with responsibilities for finance, risk and operations.

Key Details

• Boards increased to 11 directors; appointment effective February 23, 2026 (boards acted January 5, 2026).
• Manu Asthana will join the Audit Committee and the Operations Committee of each board.
• He will be a nominee for election at Alliant Energy’s 2026 Annual Meeting to serve until the 2029 Annual Meeting (he will stand for election alongside three directors whose terms expire in 2026).
• Compensation: Mr. Asthana will be paid as a non‑employee director per Alliant Energy’s April 1, 2025 proxy practices, except the 2026 annual retainer for board service will be $300,000.

Why It Matters Board appointments can affect corporate oversight and strategy. Adding a director with recent leadership at PJM—operator of the largest U.S. power grid—brings regulatory and grid‑operations experience to Alliant Energy’s governance. Investors should note the timing (appointment now, election at the 2026 Annual Meeting) and the disclosed director compensation for 2026.
