Suzhou Tianmai Thermal Technology Co., Ltd. (hereinafter referred to as "Suzhou Tianmai", "Company", "this Company", or "Issuer") and Guotai Junan Securities Co., Ltd. (hereinafter referred to as "Guotai Junan", "Sponsor (Lead Underwriter)", or "Lead Underwriter") have organized the issuance of convertible corporate bonds to non-specific objects (hereinafter referred to as "Convertible Bonds" or "Tianmai Convertible Bonds") in accordance with the "Securities Law of the People's Republic of China", the "Administrative Measures for the Registration and Issuance of Securities by Listed Companies" (CSRC Order No. 227), the "Administrative Measures for the Issuance and Underwriting of Securities" (CSRC Order No. 228), the "Shenzhen Stock Exchange Listed Company Self-Regulatory Guidelines No. 15 — Convertible Corporate Bonds (2025 Revision)" (SZSE [2025] No. 223), the "Shenzhen Stock Exchange Implementation Rules for the Issuance and Underwriting of Securities by Listed Companies (2025 Revision)" (SZSE [2025] No. 268), and the "Shenzhen Stock Exchange GEM Listed Company Self-Regulatory Guidelines No. 1 — Business Handling (2026 Revision)" (SZSE [2026] No. 135), and other relevant regulations.
The Convertible Bonds to be issued will be preferentially subscribed by existing shareholders of the Issuer after the close of trading on the share registration date (July 31, 2026, T-1 day), as registered with China Securities Depository and Clearing Corporation Limited Shenzhen Branch (hereinafter referred to as "ChinaClear Shenzhen Branch"). The remaining portion after the preferential subscription by existing shareholders (including the portion of preferential subscription waived by existing shareholders) will be issued online to the general public investors through the Shenzhen Stock Exchange (hereinafter referred to as "SZSE") trading system.
Investors are advised to carefully read this announcement and the relevant regulations published on the SZSE website (www.szse.cn).
Important reminders regarding the issuance process, subscription, payment, and investor abandonment of subscriptions are as follows:
-
The preferential subscription date for existing shareholders and the online subscription date are both August 3, 2026 (T day). The subscription period is T day 9:15-11:30 and 13:00-15:00. When participating in preferential subscription on August 3, 2026 (T day), existing shareholders must pay sufficient funds within their preferential subscription quota according to the number of convertible bonds to be preferentially subscribed. Existing shareholders and general public investors do not need to pay subscription funds when participating in the online subscription of the remaining portion after preferential subscription.
-
Investors should determine their subscription amount based on industry regulatory requirements and their respective asset or capital scale, and should not subscribe beyond their asset or capital scale. If the Sponsor (Lead Underwriter) discovers that an investor violates industry regulatory requirements by subscribing beyond their respective asset or capital scale, it has the right to deem the investor's subscription invalid. Investors should express their subscription intentions independently and should not authorize securities companies to subscribe on their behalf in a general manner.
-
Investors can only use one securities account to participate in the online subscription of convertible bonds. If an investor uses multiple securities accounts to subscribe for the same convertible bond, or uses the same securities account to subscribe for the same convertible bond multiple times, the first subscription will be considered valid, and all subsequent subscriptions will be invalid. Once confirmed by the SZSE trading system, the subscription cannot be revoked.
