Subject of the Disclosure

ACEN announces leadership appointments to drive next phase of execution and measured growth
Background/Description of the Disclosure

November 11, 2026 — ACEN is entering a new phase focused on delivering its investment commitments, strengthening operational performance and pursuing measured growth, following a decade of rapid expansion.

ACEN has grown its attributable renewable energy capacity from approximately 100 megawatts in 2016 to around 7,500 megawatts today, representing a compound annual growth rate of over 50%. Having established a significant renewable energy portfolio across multiple markets, the company is now focused on translating this scale into stronger business performance through sharper project execution, capital efficiency and sustained profitability.

To support this strategic direction, ACEN's Board of Directors has approved the appointments of Roman Miguel G. de Jesus as Chief Executive Officer of ACEN Philippines, Ma. Cecilia T. Cruzabra as ACEN Group Chief Financial Officer and Theodore Ivan Paris as Group Treasurer effective January 1, 2027.

John Eric T. Francia continues as President and Chief Executive Officer of the listed company, ACEN. ACEN recently realigned its organization to sharpen its focus on execution, with three business units, each led by a chief executive:

ACEN Philippines – led by Roman Miguel G. de Jesus
ACEN Investments – led by Patrice Clausse (overseeing international investments, and ACEN India)
ACEN Australia – led by Jose Maria Zabaleta

The structure reinforces clear accountability for business performance and project delivery, supported by Group functions responsible for strategic alignment, capital allocation and balance sheet strength.

“Our next phase is about translating the scale we have built into stronger operating performance and long-term value,” said Francia. “We are prioritizing the successful delivery of projects, improving the efficiency of our capital and operations, and pursuing growth selectively. These leadership appointments and our organizational realignment support that direction.”

As CEO of ACEN Philippines, de Jesus will lead the Philippine business, with responsibility for project delivery, operations and commercial activities. He has served as Chief Operating Officer for the Philippine business since 2025 and previously led the establishment and growth of ACEN's retail electricity business beginning in 2016. He has also held various operating and development leadership roles within the company.

As ACEN Group CFO, Cruzabra will lead ACEN’s corporate strategy and financial management supporting capital allocation, funding, financial risk management and balance-sheet strength across its businesses as well as Sustainability Management. She currently serves as Chief Financial Officer of ACEN International and ACEN's Chief Risk Officer, and previously served as ACEN Group Treasurer. Her experience within the Ayala Group includes serving as Treasurer of Ayala Corporation, Chief Financial Officer of Manila Water and Head of Treasury and Enterprise Wide Risk Management of Globe Telecom.

As ACEN Group Treasurer, Paris will oversee the company's treasury operations. Prior to this appointment, he served as Head of Financial Risk Management, Capital Markets & Debt Management of Ayala Corporation.

Looking ahead, ACEN will continue to pursue selective investments that demonstrate strong economics, sound commercial arrangements and strategic relevance. Its immediate priorities are to bring projects under construction into operation, improve the performance of existing assets and align capital deployment with market conditions.

As part of this strategic direction and focus, ACEN is streamlining its pipeline and plans to voluntarily relinquish some service contracts, consistent with the Department of Energy’s ongoing service contract cleanup initiative.

“Renewable energy remains a compelling long-term opportunity,” Francia added. “We will continue to invest where we see clear strategic and economic value, while ensuring that our existing portfolio delivers on its full potential.”
