Were Barry Ticho’s STOK share sales under a Rule 10b5-1 trading plan?

Yes. A footnote states the transactions were executed pursuant to a Rule 10b5-1 trading plan adopted on November 19, 2025. Such plans pre-schedule trades, meaning timing is predetermined and typically reflects routine portfolio or compensation management rather than opportunistic market timing.

Were any of the STOK share sales related to tax withholding for Barry Ticho?

Yes. One footnote explains that part of the reported transaction represents an issuer-mandated sale to satisfy tax withholding obligations from vesting and settlement of restricted stock units. These tax-driven sales are mechanical events and not discretionary open-market sales for investment reasons.
