On 19 October 2026 Slootman exercised 300,000 fully vested options at $8.88 (expiry 28 May 2029) and sold 300,000 shares across ten transactions at weighted averages of $311.06–$319.995, gross about $94.93m. Form 4 accepted 21 October at 18:59 ET. Sales under a Rule 10b5-1 plan adopted 19 September 2025.

The contrarian hypothesis I tested: that a share-count plan can still carry information if the operator varies the cadence, front-loads it, or lets the dollar take increase as the stock runs — in which case the “it’s just a plan” dismissal is lazy.

It did not survive. The count is 300,000 every month, to the share. The option balance steps down by exactly 300,000 each time. Crucially, October’s proceeds were the lowest of the four despite the identical share count — he sold into a price band roughly 6% below September’s, collecting about $95m where September collected about $100m. That is the discriminating fact. A plan denominated in shares is indifferent to price by construction; a discretionary seller, or a dollar-denominated plan, would have varied the count inversely with the price. The count did not move. There is no information in it.

Two supporting details point the same way. His 210,029 shares held across five trusts — the Slootman Living Trust, a Grandchildren’s Trust, a 2023 Children’s Trust and two mirrored 2024 GRATs holding 56,331 each — have not been touched across any of the four filings. And 3,836,655 options remain, roughly 12.8× the monthly take. Someone exiting sells the trusts and the stock; someone running a plan sells the option stack and leaves the estate structure alone.

The ordinary reading, stated plainly “Large insider sale under a long-standing 10b5-1 plan, no signal” is correct here, and the reason it is correct is the fixed share count rather than the existence of the plan. The existence of a plan proves nothing on its own — plans get amended, cancelled and restarted, as Edition 040 documented elsewhere. The uniform count across four months is what does the work.
