Auditor Dismissal and New Engagement
On July 21, 2026, the Audit Committee dismissed EY as independent auditor, effective upon filing of the Q2 2026 10-Q, and engaged KPMG for fiscal year 2026. The change is due to EY's loss of independence after the pending merger closes.
-
Prior Material Weakness in Internal Controls
EY's audit report for fiscal year 2024 contained an adverse opinion on internal control over financial reporting due to a material weakness in controls related to the disposition process of AES Brasil.
-
Impermissible Services by Incoming Auditor
KPMG member firms provided impermissible services (tax advisory, payroll, legal advice, financial model review) to foreign subsidiaries during the audit period. All such services were completed or terminated before KPMG's appointment, and both KPMG and the Audit Committee concluded objectivity was not impaired.

Merger Context
The auditor change is directly tied to the pending acquisition by a consortium led by Global Infrastructure Partners and EQT Infrastructure VI, approved by stockholders on June 26, 2026, at $15.00 per share.
Analysis · AES · Energy & Transportation
AES dismissed EY as its auditor effective upon filing its Q2 2026 10-Q, citing EY's loss of independence after the pending merger closes. The company engaged KPMG as its new auditor, but disclosed that KPMG member firms had provided impermissible services to foreign subsidiaries during the audit period — though these were terminated and deemed immaterial. Critically, the filing reveals that EY had issued an adverse opinion on internal controls as of December 31, 2024 due to a material weakness related to the AES Brasil disposition. While the auditor change is driven by the merger, the disclosure of a prior material weakness and the impermissible services by the incoming auditor raise governance concerns during a sensitive pre-close period.
At the time of this filing, AES was trading at $14.84 on NYSE in the Energy & Transportation sector, with a market capitalization of approximately $10.6B. The 52-week trading range was $12.33 to $17.65. This filing was assessed with negative market sentiment and an importance score of 8 out of 10.
