Alliant Energy Corporation (LNT) � Form 4 filing

Director Ignacio A. Cortina reported the grant of 759 Deferred Common Stock Units on 11 July 2025 under transaction code “A� (award). Each unit represents the right to receive one share of LNT common stock upon the director’s departure from the board. The filing lists an indicative reference price of $62.08 and brings Cortina’s total deferred stock balance to 7,916.756 units, which already reflects automatic dividend reinvestment adjustments permitted under Rule 16a-11.

The award appears to be routine board compensation rather than an open-market purchase or sale; therefore, the transaction has no direct cash outlay by the director and limited immediate impact on float or insider sentiment.

Il direttore Ignacio A. Cortina ha comunicato la concessione di 759 Unità di Azioni Differite in data 11 luglio 2025 con codice transazione “A� (assegnazione). Ogni unità rappresenta il diritto a ricevere una azione ordinaria LNT al termine del mandato nel consiglio. Il documento indica un prezzo di riferimento indicativo di 62,08 $ e porta il saldo totale delle azioni differite di Cortina a 7.916,756 unità, già comprensive degli aggiustamenti automatici per il reinvestimento dei dividendi consentiti dalla Regola 16a-11.

L’assegnazione sembra essere una normale compensazione per il consiglio e non un acquisto o vendita sul mercato aperto; pertanto, la transazione comporta nessuna uscita di cassa diretta da parte del direttore e un impatto immediato limitato sul flottante o sul sentimento degli insider.

Insights

TL;DR � Routine director compensation, neutral signal.

The 759-unit award (~$47 k at $62.08) modestly increases the director’s ownership to nearly 8 k units but is part of Alliant’s standard equity retainer. Because it is not an open-market buy, it does not convey incremental confidence in the stock. Nor does it introduce dilution—the units are already reserved under the company’s equity plan and settle only at board departure. Overall, the filing is administratively necessary but immaterial to valuation, liquidity, or governance risk.

TL;DR � Standard equity grant, governance practices intact.

Alliant Energy continues to compensate directors predominantly with deferred stock, aligning their interests with long-term shareholder value. The grant follows Section 16 guidance and acknowledges dividend reinvestments, indicating sound compliance. No red flags emerge regarding board independence or excessive compensation. Impact on governance posture is neutral.
