Terminal margin basis

Own normalised economics via an opex bridge that reconciles to the dollar against EDGAR; State A licenses this. 0.78pp BELOW the FY2026 trailing actual of 46.78%, with the gap caused, quantified and CFO-stated three quarters running (AI capacity gross-margin drag, offset by observed opex leverage: FY2026 gross margin -0.86pp while operating margin +1.15pp).

Risk & exit

Four distinct questions, one field each. A price is not a thesis: the trigger below forces a re-underwrite and freezes further purchases — it is never an automatic sell.

Risk trigger
12% below the memo price
$354.18

A daily close below $354.18 triggers a mandatory re-underwrite and freezes further purchases. It is not an automatic sell unless a separate fundamental invalidation condition has been breached.

Thesis-invalidation conditions

Fundamental and falsifiable, never price-based. If one is satisfied the thesis is marked dead and the position is retained only by explicit decision.

Impairment case

Not stated. No permanent-loss case with a named cause is on file. A valuation bear case is not an impairment case.
