11. Item 4 (Resignation, Removal or Election of Directors or Officers)

We disclose that at the meeting of the Board of Directors of PLDT Inc. (respectively, the “Board” and the “Company”) held on September 16, 2025:

The Board accepted the resignation of Mr. Kazuyuki Kozu as director of the Company, effective at the close of business on September 15, 2025. The Board conveyed its sincere gratitude to Mr. Kozu for his valuable contributions and wished him all the best in his ongoing endeavors.

The resignation of Mr. Kozu is not expected to have any significant impact on the Company’s current or future operations, financial position, or results of operations.

As recommended by the Governance, Nomination and Sustainability Committee which conducted the screening process and determined that director-nominee Mr. Hidetada Hayashi possesses all the qualifications and has none of the disqualifications for directorship, the Board elected Mr. Hayashi as director of the Company to hold office effective immediately and for the unexpired term of his predecessor in office, Mr. Kozu.

Mr. Hayashi was likewise appointed, vice Mr. Kozu, as an advisor of the Audit Committee, and as a member of the following board committees: (a) Governance, Nomination and Sustainability Committee; (b) Risk Committee; (c) Executive Compensation Committee; (d) Technology Strategy Committee; and (e) Data Privacy and Information Security Committee, effective immediately.

Mr. Hayashi joined NTT, Inc. in April 1994 and has over 30 years of experience in the telecommunications industry. He currently serves as the Managing Director of the Philippine Branch of NTT DOCOMO, INC.

Prior to this, he served as the Director of the Business Management Division of NTT DOCOMO GLOBAL, Inc. from 2024 to 2025, Executive Director of the Corporate Planning Department of NTT DOCOMO, INC. from 2022 to 2024, and Chief Operating Officer of DOCOMO Communications Laboratories Europe GmbH from 2018 to 2021.

Mr. Hayashi earned a Bachelor of Arts degree in Law from Chuo University, Tokyo in 1994.
