1 more insider, included withMeasure
Each person’s holding as they reported it after each open-market trade, over the last twelve months. It counts one class of stock and excludes grants, option exercises and shares withheld for tax, so a stake can fall here while somebody’s total holding does not. Since April 2023 a Form 4 states whether a trade ran under a pre-arranged 10b5-1 plan; an older one does not, and those dollars read “not stated” rather than being counted either way.
The assistant answers from what AGL has actually filed: 7 annual reports filed with the SEC, 40 Form 4 filings from the last year, 13F positions from the 1 tracked investor who hold it and 6 funds that hold it. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from AGL's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 AGL insiders have filed, not the latest few.
Ten seconds, no card, and nothing to cancel.

From SEC Form 4 filings, filed by officers, directors and 10%-owners within two business days of a transaction. “Indirect” holdings (a trust, an LLC, a family member) are included and not distinguished from direct ones in this table.
Past transactions say nothing about future ones, and none of this is investment advice.
