The filing shows no open-market sales. Instead, 9,697 Class A Common shares were withheld by Marqeta at $3.89 per share to satisfy tax obligations from RSU vesting, which the footnotes clarify was not a market transaction but an issuer tax-withholding arrangement.

A total of 38,889 restricted stock units vested for Sarah Barkema on March 1, 2026. Each RSU is convertible into one share of Marqeta Class A Common Stock, so the vesting resulted in the issuance of an equal number of common shares to her account.
