Marqeta loses its accounting chief—but flags no financial disagreement

The filing breaks the standing assumption of accounting leadership continuity. Marqeta disclosed that Chief Accounting Officer and SVP of Finance Sarah Barkema will resign effective August 21, 2026; the filing gives no indication that this departure was previously announced or expected. (Item 5.02)

The immediate coverage plan reduces the operational risk. CFO Patti Kangwankij will assume the principal accounting officer role, so the company is not leaving the accounting function without executive oversight while it searches for a permanent replacement. (Item 5.02)

There is no disclosed evidence of a reporting or control problem. Marqeta specifically says Barkema’s resignation was not caused by a disagreement over financial statements, internal controls, operations, policies, or practices. That makes this a personnel transition—not a disclosed restatement, accounting dispute, or control failure. (Item 5.02)

Net: modestly worse than an unchanged leadership setup, but not a financial-warning event. The surprise loss of the accounting chief and the open-ended replacement search create a small execution and continuity overhang. The CFO’s interim assumption and the explicit denial of financial disagreements keep the signal from becoming more severe.
