TWILIO INC 4

Twilio CFO Aidan Viggiano sold 1,394 shares of Class A common stock on August 17, 2026, in mandated sell-to-cover transactions related to RSU vesting.

On August 17, 2026, Twilio Inc. Chief Financial Officer Aidan Viggiano executed a series of automatic open-market sales of Class A common stock solely to cover statutory tax withholding obligations arising from the vesting of restricted stock units, as required under the company’s equity incentive plan “sell‑to‑cover” election. The transactions comprised four small tranches totaling 1,394 shares sold at weighted average prices between approximately $233.32 and $238.10 per share, generating an aggregate value of roughly $326,000 and reducing the CFO’s direct holdings to 108,330 Class A shares. Given the routine, non-discretionary nature of the tax-withholding sales and the relatively modest size versus both the insider’s remaining stake and Twilio’s market capitalization, the activity appears as standard compensation-related housekeeping rather than a directional signal on the stock.
