This price chart is drawn by TradingView, from their own data, in an embed loaded from their servers. We hold too few licensed daily closes of our own for ATHA to draw a line in its place.
ATHA has no Form 4 filing in the last 90 days, so there is no summary for that window. The most recent filings we hold are below, the newest dated 2 January 2026.

Compensation mechanics
Share grants, option exercises, tax withholding and transfers. They reach the same Form 4 as a trade, but they are not the insider buying or selling on the open market, so no purchase or sale value applies to them.
