Nippon Sheet Glass (the “Company” or “NSG”) announces that a resolution was passed by the Board of Directors today to issue new common shares (the “New Shares”) through a third-party allotment of 165 billion yen (the “Third-Party Allotment”), corresponding to the total amount paid by Lumina Japan Acquisition Co., Ltd. (the “Allottee”), a special purpose company owned by funds managed by affiliates of Apollo Global Management, Inc. (“Apollo Funds”) and its subsidiaries (collectively “Apollo”). In addition to the above, at the Board of Directors meeting held today, the Company passed a resolution to submit a proposal regarding the Third-Party Allotment and a proposal regarding a partial amendment to the Articles of Incorporation in order to increase the total number of authorized shares of the Company necessary for the implementation of the Third-Party Allotment (the “Proposals Related to Third-Party Allotment”) to the annual general meeting of shareholders to be held on late June 2026 (the “Annual General Meeting of Shareholders”).

At the Board of Directors meeting held today, the Company has also passed a resolution to submit to the Annual General Meeting of Shareholders a proposal to consolidate 122,222,222 common shares into 1 share and make a cash payment to the shareholders of the Company other than the Allottee, equivalent to 500 yen per share of the Company common shares prior to the share consolidation (the “Share Consolidation”) and a proposal for a partial amendments to the Articles of Incorporation with respect to the abolition of the share unit system (together with the Proposals Related to the Third-Party Allotment, collectively referred to as the “Proposals to be Submitted to the Annual General Meeting of Shareholders”) to ensure that the Allottee becomes the Company’s sole shareholder.

The above resolutions from the Board of Directors were made on the premise that the Allottee intends to make the Company its wholly-owned subsidiary through the Third-Party Allotment and the subsequent Share Consolidation (as the “Wholly-Owned Transaction”), as well as funds from the Third-Party Allotment will be used to repay the existing borrowings of the Company’s U.K. subsidiary and to deliver money to the minority shareholders as a result of the Share Consolidation (for details, please refer to “(2) Specific Use of Proceeds and Timing” within “3. Amount, Use and Timing of Proceeds” and “II. Issuance of new shares through the Third-Party Allotment”), and the Company’s common shares are set to be delisted. Given the necessary time for the completion of expected procedures and filings under the domestic and foreign competition laws and foreign direct investments laws and regulations and foreign subsidies regulations in relevant jurisdictions, based

on the share subscription agreement (the “Share Subscription Agreement”) concluded between the Company and the Allottee, the conditions for the execution of the Third-Party Allotment (the “Condition Precedent”. For details, please refer to “(4) Major Agreements under Related Agreements” within “2. Purpose and Background of the Third-Party Allotment” of “II. Issuance of new shares through the Third-Party Allotment” below) includes that all of the proposals to be submitted to the Annual General Meeting of Shareholders are approved and that all the regulatory procedures are completed. The Share Consolidation will become effective on the condition that the Third-Party Allotment is executed.

Furthermore, on the Effective Date of the Share Consolidation, SMBC, DBJ, Mizuho, and SMTB (the “Major Financial Institutions”) plan to make a cash contribution of 140 billion yen in the Company through a limited partnership managed by Apollo Funds and the Allottee. The Company plans to repay all the borrowings from the Major Financial Institutions by using the funds received from the Allottee on the same day (the “Quasi-DES”) (please refer to scheme diagram in “I. Transaction process and timeline” for details). The Quasi-DES is intended to lead to future growth through recapitalization following the equity conversion of the Company’s debt. It is confirmed that the Definitive Agreement has been executed today with Apollo Funds and the Major Financial Institutions.

In addition, the Company also announces that its parent company and largest shareholder are expected to change following the Third-Party Allotment.
