VOLUNTARY ANNOUNCEMENT

FORMATION OF THE FUND

This announcement is made by APT Electronics Co., Ltd. (the "Company", together with its subsidiaries, the "Group") on a voluntary basis.

The Board hereby announces that the Company (as the limited partner) intends to enter into a partnership agreement (the "Partnership Agreement") with Dazhong Juding (Shanghai) Private Equity Fund Management Co., Ltd. (大眾聚鼎(上海)私募基金管理有限公司) (as the general partner and independent third party), Dazhong Transportation (Group) Co., Ltd. (大眾交通(集團)股份有限公司) (listed on Shanghai Stock Exchange, stock code: 600611.SH, 900903.SH as the independent third party) and four other independent third parties (all as the limited partners) jointly, for the purpose of the establishment of a private equity investment fund ("Fund") named "Maanshan Zhongsong Jingchuang Venture Capital Partnership (Limited Partnership)" (馬鞍山眾松晶創創業投資合夥企業(有限合夥)) with a size of RMB150 million (the "Transaction"). The Group's committed capital contribution in cash in the Fund amounts to RMB20 million, representing approximately $13.3333\%$ of the total capital commitment of the Fund. The capital contribution of the Company to the Fund will be paid from the internal resources of the Company. It is expected that, upon establishment, the Fund will not be accounted for as a subsidiary of the Company. Dazhong Juding (Shanghai) Private Equity Fund Management Co., Ltd. will be the fund manager of the Fund according to the Partnership Agreement.

As of the date of this announcement, the Fund has yet to complete the fund filing procedures in Asset Management Association of China.

• For identification purpose only

---

The investment scope of the Fund will mainly focus on investment targets in semiconductors, artificial intelligence, automotive electronics and other fields.

This Transaction implements the Company’s consistent investment strategy. The Group expects to generate sustainable investment returns by identifying and investing in high-potential and strategically aligned targets, while also fostering and enhancing strategic partnerships with upstream and downstream enterprises in the industrial chain through capital linkages. In this Transaction, the Group can fully leverage the resources of the Fund’s professional investment team to effectively manage the risks of mergers, acquisitions, and innovation projects through the Fund, ensure the quality of target companies and reserve high quality strategic project resources, and enhance the Group’s medium and long-term sustainable development.

The highest applicable percentage ratio for the Transaction calculated under Chapter 14 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the “Listing Rules”) is lower than 5% and the counterparties are independent third parties of the Company. Therefore, the Transaction does not constitute a disclosable transaction of the Company under Chapter 14 of the Listing Rules, nor does it constitute a connected transaction under Chapter 14A of the Listing Rules. The announcement is published on a voluntary basis.

The Transaction still needs to go through relevant regulatory procedures such as filing, and there is certain degree of uncertainties about the specific implementation and progress. Shareholders of the Company and potential investors are therefore advised to exercise caution when dealing in the securities of the Company.

For ease of reference, the names of the PRC established companies or entities have been included in this announcement in both the Chinese and English languages, and in the event of any inconsistency, the Chinese versions shall prevail.
