Uncas GP LLC 4

What Happened
Andrew J. Stafman, a director of Twilio Inc., was granted 688 restricted stock units (RSUs) on March 15, 2026. The RSUs vested immediately, each representing the right to one share of Twilio Class A common stock; the grant is reported at $0 cash paid. Per the filing, Stafman immediately granted all rights in these securities to Sachem Head (his investment firm) for no consideration, so the economic interest was assigned away rather than retained personally.

Context
This was an awarded and immediately vested RSU grant (not a market purchase or sale) and was assigned to Stafman’s investment firm, Sachem Head. Such director RSU grants are often part of compensation arrangements; because the award was transferred to an affiliated investment manager, it primarily reflects an administrative/compensation and allocation action rather than a direct personal buy or sell by the director.
