18 transactions on file (0 open-market purchases and 11 open-market sales).
11 open-market sales by PACB insiders, between Feb 17, 2026 and Aug 17, 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.
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.
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 two above it was.

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 PACB has actually filed: 17 annual reports filed with the SEC, 18 Form 4 filings from the last year and 5 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 PACB's filings and figures. One a day without an account; a free account has its own, and no card.

Past transactions say nothing about future ones, and none of this is investment advice.
