Subject of the Disclosure

Alternergy conducts an in-person Annual Stockholders Meeting; four projects' progress and election of new independent director announced

Background/Description of the Disclosure

Alternergy Holdings Corporation (“ALTER”), a Philippine pioneer in renewable power development, during its Annual Shareholders Meeting (“ASM”) conducted in-person at New World Hotel, Makati City, highlighted significant progress across four (4) renewable energy projects and stronger financial performance as it prepares to bring its two largest wind developments into commercial operations and advance a 464-megawatt (MW) pipeline. The 28-megawatt (“MWp”) Balsik Solar Farm commenced commercial operations in February 2026, followed by the 4.6 MW Dupinga Run-of-River Hydro Power Plant in March. Meanwhile, the 64 MW Alabat Wind Farm and the 128 MW Tanay Wind Farm have both started generating commissioning revenues ahead of full commercial operations. Alabat is scheduled to begin commercial operations in December this year, followed by Tanay in January 2027. Beyond its current projects, Alternergy is advancing its next phase of development through projects awarded under the Department of Energy’s fourth Green Energy Auction (“GEA 4”).

In the same ASM, veteran banker Valentino Bagatsing was elected as independent director of ALTER. Mr. Bagatsing has more than four decades of experience in corporate finance, capital markets, development finance, and infrastructure investments, further strengthening ALTER’s Board as the company enters its next phase of growth.
