Marqeta, Inc. Chief Accounting Officer Resigns Effective Aug 21, 2026

What Happened

• Marqeta, Inc. reported in an 8-K filed Aug 13, 2026 that Sarah Barkema, its Chief Accounting Officer, Senior Vice President of Finance and principal accounting officer, informed the company on Aug 10, 2026 that she will resign effective Aug 21, 2026. The company said her departure is not due to any disagreement related to financial statements, internal controls, operations, policies or practices.

Key Details

• Resignation notice given Aug 10, 2026; effective Aug 21, 2026.
• Patti Kangwankij, the company’s Chief Financial Officer and current principal financial officer, will assume the role of principal accounting officer after Barkema’s departure.
• The company will search for a new Chief Accounting Officer.
• The filing states Patti Kangwankij has no transactions requiring Item 404(a) disclosure and no new or materially amended plans/contracts or grants were made due to her new principal accounting officer role; background info is in Marqeta’s proxy filed Apr 10, 2026.

Why It Matters

• This is a leadership change in Marqeta’s accounting function, which is important for financial reporting and internal controls. Having the CFO temporarily serve as principal accounting officer signals continuity, but investors may want to watch for the appointment of a permanent CAO and any related disclosures. The company’s statement that the departure was not due to disagreements over financial reporting reduces immediate regulatory/financial red-flag concerns.
