Summary
Momentus replaced its independent auditor, dismissing Frank, Rimerman effective August 11, 2026, and engaging Baker Tilly two days later. The change occurred without disagreements on accounting principles or practices.
The filing discloses that the company's most recent 2025 audit opinion was unqualified and did not include going concern language, an improvement from the 2024 audit which flagged substantial doubt about the company's ability to continue as a going concern. The auditor change follows the company's successful remediation of a material weakness in internal controls as of December 31, 2025.
The weakness related to misclassification errors in accounting for certain matters. Momentus addressed this through enhanced internal controls and ongoing monitoring and testing. For retail holders, the combination of remediated controls and removal of going concern language suggests improved operational and financial stability, though the auditor switch itself warrants monitoring of the transition to Baker Tilly.
