• Price range reported across transactions: approximately $187.00 to $189.26 (footnotes state the listed prices are weighted averages from multiple trades within those ranges).

• Material footnotes: sales were effected under a Rule 10b5‑1 trading plan adopted November 14, 2025 for the benefit of relatives; some shares sold were held in or by family trusts for which Ullal serves as trustee/co‑trustee and she disclaims beneficial ownership of those trust shares. The filer offers to provide per‑trade breakdowns upon request per the footnotes.

Context

• These were planned sales under a 10b5‑1 arrangement (prearranged trading plan), which means the transactions were pre-authorized rather than necessarily reflecting a contemporaneous view of the stock. For retail investors, purchases typically convey stronger positive signals than routine, preplanned sales; this filing documents a sizeable, preplanned disposition by the company’s CEO.
