Impact Analysis of the Capital Increase and Share Expansion Event of a Subsidiary of Yongding Co., Ltd.

This capital increase and share expansion event of Dingxin Optoelectronics, a holding subsidiary of Yongding Co., Ltd., involves a cash injection of 55 million yuan and a minor adjustment to the equity structure. From a financial perspective, since Yongding Co., Ltd. and its holding subsidiaries still maintain a controlling stake of 52.4914%, this capital increase is an equity transaction. The funds invested by external investors, after deducting the corresponding net asset share, will be included in the capital reserve of the parent company’s consolidated statement and not included in current profits and losses [0]. At the same time, the 55 million yuan cash obtained by Dingxin Optoelectronics will be included in the cash inflow from financing activities of the parent company’s consolidated statement, improving the stability of the subsidiary’s cash flow and indirectly optimizing the asset-liability ratio and liquidity of the parent company’s consolidated statement [0].

At the business level, the introduced external investors include optical communication equipment manufacturer Cambridge Technology (603083.SS) and a number of industrial/government funds, which have obvious upstream and downstream collaboration and resource empowerment effects. As an optical communication equipment manufacturer, Cambridge Technology forms a direct upstream-downstream relationship with Dingxin Optoelectronics’ optical chip business and is expected to provide it with stable customer channels [0]. In addition, the 55 million yuan capital increase can be used for R&D investment and capacity expansion in the optical chip field, enhancing Dingxin’s competitiveness in high-end optical chips (such as 100G/400G) [0]. Other industrial fund investors like Wuxi Jicui and Suzhou Longju can also provide technical resources and policy support to accelerate the development of Dingxin Optoelectronics [0].

This event reflects the continuous popularity of the optical chip track and the trend of industrial integration. As popular stocks in the optical communication sector, Yongding Co., Ltd. and Cambridge Technology have seen their stock prices rise by 382.23% and 231.39% respectively since 2025. This capital increase and share expansion further strengthens the market’s optimistic expectations for the optical chip industry [0]. The strategy of introducing industrial investors rather than financial investors indicates that Yongding Co., Ltd. focuses more on the long-term business development of Dingxin Optoelectronics rather than short-term financial returns, aiming to enhance the core competitiveness of the optical chip business through industrial collaboration and resource integration.

1. Growth in demand for optical chip industry: The rapid development of the optical communication industry drives continuous growth in demand for optical chips, and Dingxin Optoelectronics’ technology and capacity expansion are expected to seize market opportunities.
2. Industrial collaboration effect: Cooperation with upstream and downstream enterprises like Cambridge Technology is expected to improve product quality and market share.

1. Formality of the announcement: Currently, no official announcement from the Shanghai Stock Exchange/Juchao Information Network has been retrieved; details need to be verified after the company releases the official document.
2. Business integration risk: The actual effect of industrial collaboration and resource integration needs to be tracked and verified later, and there is a risk that integration may not meet expectations.
3. Technology competition risk: The optical chip industry has rapid technological iteration, and the effect of R&D investment is uncertain.

This capital increase and share expansion event of Dingxin Optoelectronics, a subsidiary of Yongding Co., Ltd., improves the parent company’s cash flow and liquidity from the financial perspective, and enhances the competitiveness and industrial collaboration capability of the optical chip business from the business perspective. On the day of the announcement, the company’s stock price rose by 3.06%, with a positive market response.
