Nanjing Sample Technology Company Limited (SAMPLE TECH) has dispatched a circular convening its 2026 annual general meeting (AGM) for 26 June 2026 in Nanjing, Jiangsu. Key items up for shareholder approval include a fresh general mandate empowering the board to issue up to 20% of both Domestic Shares and H Shares.

Share base and potential issuance • As of the latest practicable date (21 May 2026), SAMPLE TECH had 792.06 million shares outstanding, comprising 562.56 million Domestic Shares and 229.50 million H Shares. • The proposed mandate would authorise the board to allot, issue, resell or transfer up to 112.51 million new Domestic Shares and 45.90 million new H Shares—equivalent to 20% of each respective class, excluding any treasury shares. • The authority will remain valid until the earliest of (i) the next AGM, (ii) the statutory deadline for holding the next AGM, or (iii) any earlier revocation by shareholders.

Additional AGM agenda Shareholders will also vote on five ordinary resolutions: 1. Adoption of the directors’ report for 2025. 2. Approval of the Group’s audited consolidated financial statements for 2025. 3. Approval of the 2025 profit distribution plan. 4. Re-appointment of WUYIGE Certified Public Accountants LLP as external auditor for 2026 and authorisation for the board to set its remuneration. 5. Approval of the statutory reserve fund appropriation for 2025.

Meeting logistics • Date & time: 26 June 2026, 10:00 a.m. (Beijing time) • Venue: No. 10 Maqun Avenue, Qixia District, Nanjing, Jiangsu, PRC • Shareholders must lodge proxy forms with Computershare Hong Kong Investor Services or the company’s PRC office at least 24 hours before the meeting.
