Insights

Audit & Governance Analyst

Stem changes auditors from Deloitte to RSM with no reported disputes.

Stem, Inc. is replacing Deloitte & Touche LLP with RSM US LLP as its independent auditor, effective with the review of the quarter ending March 31, 2026 and the audit of the year ending December 31, 2026.

The company states that Deloitte’s reports for 2024 and 2025 were clean and that there were no disagreements or reportable events under Item 304 of Regulation S-K through March 12, 2026. This points to a routine firm change rather than one triggered by disclosed accounting issues.

The engagement of RSM is subject to customary client acceptance procedures, a standard step in auditor transitions. Investors may focus on future filings for any changes in audit-related fees, internal control commentary, or disclosure style once RSM begins reviewing the March 31, 2026 quarterly financial statements.

The Company has provided Deloitte with a copy of the disclosures made by the Company in response to this Item 4.01 and has requested that Deloitte furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the registrant in response to this Item 4.01 and, if not, stating the respects in which it does not agree.
