[Form 4] Marqeta, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Marqeta, Inc. reported equity award activity for its Principal Accounting Officer on a Form 4. On December 1, 2025, several restricted stock unit (RSU) awards were converted into Class A Common Stock, with transactions coded “M” as exempt option or derivative exercises at an exercise price of $0 per share.

To cover tax withholding tied to these RSU vestings, the issuer withheld shares in transactions coded “F,” including 6,274, 3,001, and 422 shares at a price of $4.735 per share, which the filing notes were not market sales but shares retained by the company for tax remittance. After these transactions, the officer directly held 111,810 shares of Class A Common Stock and continued to hold derivative positions in RSUs that each convert into one share upon vesting on specified future dates, subject to continued service.
