Subject of the Disclosure

Alternergy Holdings Corporation ("ALTER") receives a letter from the SEC-OGA, imposing a penalty as regards misstatements in ALTER's Consolidated Statements of Cash Flows for the period ended 30 June 2024.

Background/Description of the Disclosure

In a Letter from the Office of the General Accountant of the Securities and Exchange Commission (“SEC-OGA”) dated 24 September 2026, received by ALTER today, 25 September 2026, the SEC-OGA imposed a penalty of PhP78,623.10 plus daily penalty of PhP29,000.00, totaling PhP107,623.10, pertaining to misstatements in ALTER’s Consolidated Statements of Cash Flows for the period ended 30 June 2024.

Specifically, the SEC-OGA imposed the penalty based on their evaluation that certain cash flow items under investing activities should have been classified as cash flows under financing activities. To wit, net cash flows used in investing activities for the period ended 30 June 2024 was reported as PhP 1.505 billion when it should have been PhP 1.427 billion, resulting in a classification error of PhP78.623 million.

In the same letter, the SEC-OGA did not require an amendment or reissuance of the Consolidated Audited Financial Statements as of 30 June 2024.
