Subject of the Disclosure
Board Approval of Proposed Acquisition by JGS of OPMC Shares Held by JGSCSC
Background/Description of the Disclosure
On October 22, 2026, the Board of Directors of JG Summit Holdings, Inc. (“JGS”) approved the proposed acquisition from its wholly owned subsidiary, JG Summit Capital Services Corp. (“JGSCSC”), of 37,051,952,896 common shares in Oriental Petroleum and Minerals Corporation (“OPMC”), a company listed on the Philippine Stock Exchange (“PSE”). The shares to be acquired comprise 8,396,391,875 OPM “A” shares and 28,655,561,021 OPM “B” shares as of September 30, 2026. The transaction will be carried out through a cross-block sale to be executed through the facilities of the PSE, targeted for completion on October 26, 2026, or on such other date as may be necessary or appropriate, subject to applicable laws, rules and regulations and the terms and conditions approved by JGS. The price per share will be equivalent to the 30-day volume-weighted average price (“VWAP”) of OPMC shares, calculated up to and including the close of trading on October 23, 2026. Accordingly, the final price per share and aggregate consideration will be determined after the VWAP calculation period ends. The proposed acquisition is intended to consolidate JGS’s investment in OPMC at the parent level.
