(II) INFORMATION ON THE OPERATION RESULTS AND FINANCIAL STATUS

Operation Results, Financial Status and Key Factors Affecting Operation Results during the Reporting Period

As disclosed in the Announcement, the key reasons for the changes in performance in the Year 2025 compared to the Year 2024 are as follows:

(i) During the Year 2025, the Company benefited from steady demand expansion in the downstream automotive electronics sector, and the sales of the Company's automotive electronics products continued to grow. The energy and industrial automation sector showed signs of recovery, with the demand of most customers in the sectors of photovoltaics and energy storage returning to normal levels, and the demand of customers in the server power sector growing rapidly driven by AI; and the consolidation of Shanghai MagnTek Microelectronics Co., Ltd. ("MagnTek") enriched the Company's product portfolio, with its business contributions positively impacting the revenue growth for the current period.

(ii) For Year 2025, the Company achieved operating revenue of approximately RMB3,367,823,100, representing a year-on-year increase of 71.80%; as well as net loss attributable to equity shareholders of the Company of approximately RMB241,076,700; and net loss attributable to equity shareholders of the Company after deducting non-recurring gains and losses of approximately RMB289,721,100. Driven by the strong growth in operating revenue, the losses of the Group are expected to narrow compared to the same period last year.

---

(iii) As at the end of 2025, the total assets of the Group were approximately RMB9,674,333,400, representing a year-on-year increase of 26.07%; the total equity attributable to equity shareholders of the Company was approximately RMB7,584,978,900, representing a year-on-year increase of 27.64%; and net assets per share attributable to equity shareholders of the Company were approximately RMB46.94, representing a year-on-year increase of 12.59%. The aforesaid increase was primarily attributable to the listing of the Company on the Main Board of The Stock Exchange of Hong Kong Limited and the corresponding issuance of H shares in December 2025.

Key Reasons for Changes of Over 30% in Key Financial Data and Indicators

During the Year 2025, the operating revenue of the Company is expected to increase by 71.80% year-on-year, primarily attributable to the following two aspects: (1) steady demand expansion in the downstream automotive electronics sector, and the sales of the Company's automotive electronics products continued to grow. The energy and industrial automation sector showed signs of recovery, with the demand of most customers in the sectors of photovoltaics and energy storage returning to normal levels, and the demand of customers in the server power sector growing rapidly driven by AI; and (2) the consolidation of MagnTek enriched the Company's product portfolio, with its business contributions positively impacting the revenue growth for the current period.

The increase in the operating loss, total loss, net loss attributable to equity shareholders of the Company, and basic loss per share was primarily due to the concurrent improvement on both the revenue and expense aspects:

(i) On the revenue aspect, the recovery in downstream market demand and the aforesaid other factors have led to a significant increase in the shipments and revenue of the Group; and

(ii) On the expense aspect, the Company continued to deepen stringent management and improve organizational efficiency, lowering the overall expense-to-operating revenue ratio, which promoted the improvement of profitability.
