SEC Form 4 data, Q3 2024 to Q2 2026
LNT insider trading by quarter
No open-market purchase or sale by a Alliant Energy Corporation insider appears in SEC's Form 4 data for trades between Jul 01, 2024 and Jun 30, 2026. Grants, option exercises, gifts and tax withholding are not counted as trades.
From SEC's quarterly Form 3, 4 and 5 data sets: code P purchases and code S sales of common stock, by the date the trade happened. Where a fund and the people who control it each report the same block, it is counted once. Trades made in the last days of Q2 2026 but filed after it closed arrive with SEC's next quarterly release.

How to read LNT insider activity
- Open-market purchase (code P)
- An insider spending their own money at market price. This is the only buy code that reliably carries signal — it is a decision, not compensation.
- Grants and option exercises (codes A, M)
- Scheduled compensation. Most "insider buying" headlines are really this, which is why InsiderPulse weights it at a fraction of a real purchase.
- Cluster buy
- Two or more different insiders buying on the open market in the same window. One executive buying can mean anything; three is much harder to explain away.
