Stem Inc. Chief Financial Officer William Bush Departs

Stem Inc. reported the departure of its chief financial officer, triggering Item 5.02 disclosures in an 8-K filed with the Securities and Exchange Commission on June 3 2026.

The filing lists William Bush as departing from his role as Chief Financial Officer. The company did not disclose a successor or an effective date beyond the filing itself. Item 5.02 requires registrants to identify the named individual, the position involved, whether the event is a departure or election, the effective date and any cited cause. No cause was specified in the document.

The departure alters Stem Inc.'s executive leadership structure. Prior to the filing the company operated with Bush in the CFO position responsible for financial reporting, capital allocation and compliance with public-company accounting standards. The new state leaves the CFO function without its prior principal officer until a replacement is named and disclosed in a subsequent filing.

Downstream the company must satisfy SEC rules on timely disclosure of officer changes and file any required exhibits under Item 9.01. A permanent or interim CFO appointment will necessitate an additional 8-K. Public companies face accelerated deadlines for certifying financial statements and maintaining internal-control attestations under Sarbanes-Oxley; absence of a named CFO can delay or require supplemental disclosures in upcoming quarterly or annual reports.

The board of directors must also act to designate a new principal financial officer for purposes of SEC signatures and certifications.

The 8-K additionally reported matters submitted to a vote of security holders under Item 5.07 and included required financial-statement exhibits. This marks the latest executive transition at the energy-storage software provider, which has navigated multiple leadership changes while scaling commercial and utility deployments.
