Momentus Inc. Replaces Independent Auditor, Engages Baker Tilly

What Happened

• Momentus Inc. (MNTS) filed an 8‑K reporting that its Audit Committee approved the dismissal of Frank, Rimerman + Co. LLP as the company’s independent registered public accounting firm effective August 11, 2026, and engaged Baker Tilly US, LLP as the new independent auditor (engagement executed August 12, 2026).
• Frank, Rimerman’s audit reports for the years ended December 31, 2025 and December 31, 2024 did not contain adverse opinions or disclaimers. The 2024 report included an explanatory paragraph about substantial doubt regarding the company’s ability to continue as a going concern. The company disclosed a material weakness in internal control for 2024 that it says was remediated as of December 31, 2025.

Key Details

• Auditor change approved by the Audit Committee on August 10, 2026; dismissal effective August 11, 2026; Baker Tilly engagement executed August 12, 2026.
• Frank, Rimerman’s 2024 report included a going‑concern explanatory paragraph; no adverse or qualified opinions for 2024 or 2025.
• The previously disclosed material weakness in internal control (misclassification errors) was remediated as of December 31, 2025, per the company’s 2025 Form 10‑K.
• Frank, Rimerman reported no disagreements with the company during 2024–2025 and authorized responding to Baker Tilly’s inquiries; Baker Tilly had no prior consultations with the company during that period.

Why It Matters

• Auditor changes are important governance events for investors because a new auditor will perform future audits and may bring different audit focus or findings. The filing indicates no unresolved disagreements with the prior auditor and states the earlier material control weakness was remediated, which are positive governance signals.
• Investors should note the historical going‑concern disclosure in 2024 (now followed by remediation claims) and watch upcoming SEC filings and the next audited financial statements from Baker Tilly for confirmation of the company’s financial condition and any new audit observations.
