Special Reminder

Chengdu Hongming Electronics Co., Ltd. (hereinafter referred to as “Hongming Electronics,” “Issuer,” or “Company”)'s application for the initial public offering of RMB ordinary shares (A-shares) and listing on the Growth Enterprise Market (GEM) has been approved by the Shenzhen Stock Exchange (hereinafter “SZSE”) GEM Listing Review Committee and has received registration approval from the China Securities Regulatory Commission (CSRC) (Approval No. 2025-2917).

This issuance will be conducted through a combination of offline inquiry and allocation to qualified investors (hereinafter “offline issuance”) and online pricing to the general public investors holding non-restricted A-shares and non-restricted depositary receipts in the Shenzhen market with market value (hereinafter “online issuance”).

The issuer and the sponsor (lead underwriter) Shenwan Hongyuan Securities Underwriting and Sponsoring Co., Ltd. (hereinafter “Shenwan Hongyuan Underwriting and Sponsoring” or “Sponsor (Lead Underwriter)”) have negotiated and determined the total number of shares to be issued as 30,387,340 shares. The issuance price is RMB 69.66 per share.

The final issuance price will not exceed the lower of the median and weighted average of the bid prices from offline investors after excluding the highest bid, and the median and weighted average of bids from securities investment funds, national social security funds, basic pension funds, enterprise annuities, occupational pension funds, insurance funds complying with the “Measures for the Administration of Insurance Funds’ Investment” and other regulations, and qualified foreign investor funds, after excluding the highest bid. Therefore, the subsidiaries of the sponsor are not required to participate in the strategic placement of this issuance. No strategic placement will be arranged for senior management and core employees of the issuer, nor for other external investors. Based on the final determined issuance price, the sponsor’s subsidiaries will not participate in strategic placement. Ultimately, no targeted placement will be made to investors involved in strategic placement. The difference between the initial strategic placement and the final strategic placement shares, amounting to 1,519,367 shares, will be allocated back to the offline issuance.

After the strategic placement is allocated back, before the activation of the rebound mechanism for online and offline allocations, the initial offline issuance will be 21,727,340 shares, accounting for 71.50% of the total issuance; the initial online issuance will be 8,660,000 shares, accounting for 28.50%. The final combined online and offline issuance will be 30,387,340 shares, with the final distribution depending on the rebound adjustments.

Hongming Electronics will conduct an initial online pricing offering of 8,660,000 shares through the Shenzhen Stock Exchange trading system on March 16, 2026 (T day).

Investors are advised to pay close attention to the issuance process, payment procedures, and other key steps, and to fulfill their payment obligations promptly by March 18, 2026 (T+2):

The subscription funds must be fully received within the specified time; failure to do so or insufficient payment will invalidate the entire allocation. If multiple IPOs are issued on the same day and the same situation occurs, all allocations to that investor will be invalid. If multiple investors share a bank account, insufficient funds will invalidate all allocations associated with that account. For investors receiving multiple IPOs on the same day, payments should be made separately for each IPO, with proper remarks.

2. Online investors who are allocated shares must fulfill the payment obligations according to the “Results Announcement of the Online Lottery for Hongming Electronics’ IPO on the GEM,” ensuring that their securities account has sufficient subscription funds by the end of March 18, 2026 (T+2).

3. Shares allocated to offline and online investors who waive their subscription will be underwritten by the sponsor (lead underwriter).

4. The shares issued in this offering will have no trading restrictions or lock-up periods from the date of listing on the Shenzhen Stock Exchange, and will be freely tradable.

The offline portion will adopt a proportionate lock-up arrangement, whereby offline investors must commit that 30% (rounded up) of their allocated shares will be locked up for six months from the date of the issuer’s first listing and trading. The remaining 70% will be freely tradable immediately upon listing. The lock-up period for the 30% portion begins from the date of listing on the Shenzhen Stock Exchange.

Offline investors participating in initial inquiry and subscription do not need to specify lock-up arrangements for their managed allocation objects; acceptance of the inquiry implies acceptance of the disclosed lock-up terms.

5. If the total subscription amount from offline and online investors is less than 70% of the total issuance, the issuer and the sponsor will suspend the issuance and disclose the reasons and subsequent arrangements.

6. Investors who provide valid bids but do not participate in the subscription or fail to pay the full amount on time will be considered in breach of contract and liable accordingly. The sponsor will report breaches to the China Securities Industry Association. Violations will be counted across all relevant trading segments. During restrictions or bans on participation in offline inquiry and allocation, the affected investors and their managed objects cannot participate in related activities.

7. If an online investor is found to have failed to pay in full after winning the lottery three times within 12 months, they will be barred from participating in new share, depositary receipt, convertible bond, or exchangeable bond offerings for six months (180 calendar days) from the date of their most recent waiver.
