Perspective Therapeutics, Inc. (CATX) insider trading: who bought and sold

CATX insider activity

9 transactions on file (2 open-market purchases and 7 open-market sales).

Scheduled or decided

7 open-market sales by CATX insiders, between Nov 12, 2025 and Sep 4, 2026.

A sale made under a trading plan agreed months earlier is not the same event as one decided that week, and the filing itself says which.

Discretionary. The box was on the form and was not ticked. The sale was made at the prevailing price without a pre-arranged plan behind it.: $1.62M; 5 filings · 2 people
Planned (10b5-1). The filer ticked the Form 4's 10b5-1 box. The sale ran under a trading plan adopted before the trade, so it is a schedule executing rather than a view taken this week.: None; no sales on file
Not stated. The filing does not say. Either it predates the April 2023 checkbox, or nothing has re-read it since. This tab will not guess which of the other two it was.: None; no sales on file

The 2 open-market purchases on file carry no plan label.

The box can be ticked on a buy, and labelling one would qualify the rarer and more informative of the two signals.
