Xiangyang Changyuandonggu Industry Co.,Ltd. (SH: 603950) has announced plans to acquire 100% of Xiangyang Kanghao Mechanical & Electrical Engineering Co., Ltd. (Kanghao M&E) from entities controlled by its actual controllers, Li Zuoyuan and Xu Nengchen, at a transaction price of 5.01 billion yuan, alongside a private placement of up to 2 billion yuan to raise supplementary funds. The deal, which values Kanghao M&E at a 237% premium over its book value, comes as the company's market capitalization hovers below 20 billion yuan and its short-term debt burden continues to escalate rapidly.

This high-premium acquisition of related-party assets raises immediate concerns about potential tunneling, particularly given the company's deteriorating financial position. In the first half of 2026, revenue declined 2.03% year-on-year to 1.014 billion yuan, ending three consecutive years of growth. Meanwhile, interest-bearing debt surpassed 1 billion yuan for the first time in 2025 and continued climbing, with short-term borrowings surging from 100 million yuan at the end of 2023 to 615 million yuan today—a fivefold increase in just three years.

Changyuandonggu's sales model reveals deeper structural vulnerabilities. Before its 2020 IPO on the Shanghai Stock Exchange, nearly 95% of revenue came from Foton Cummins and Dongfeng Cummins, effectively binding the company to the Cummins (NYSE: CMI) joint venture ecosystem. Although the company has since diversified into new energy hybrid vehicle components for BYD and Seres, the Cummins-affiliated entities remain dominant, with Foton Cummins and Dongfeng Cummins still ranking as the top two customers. In 2025, the top five customers accounted for 84.88% of total sales.

This dependence has taken a financial toll. Accounts receivable doubled year-on-year to 850 million yuan in 2024, with receivable turnover days climbing steadily. The company's cash-to-revenue ratio has long languished between 60% and 80%, reflecting its weak negotiating position in the supply chain and the extended credit terms imposed by major customers.

Notably, the Cummins network plays multiple roles in this acquisition. Kanghao M&E derives 40.36%, 39.14%, and 38.77% of its revenue from Cummins Group and its joint ventures (including Cummins Power and Chongqing Cummins) for 2024, 2025, and the first quarter of 2026, respectively. Simultaneously, it sources 46.48%, 38.96%, and 45.46% of its purchases from the same group during these periods. Furthermore, Kanghao M&E holds a 50% stake in Cummins Power Technology Co., Ltd., alongside Cummins (China) Investment Co., Ltd.

After the transaction completes, the controlling shareholders and Cummins will have effectively cashed out through a related-party arrangement. What remains for public market investors are the unresolved questions surrounding Kanghao M&E's operational independence, the sustainability of its profitability, and whether the 237% valuation premium is genuinely justified. The inherent conflicts of interest in this interwoven corporate structure warrant close scrutiny from minority shareholders.

These structural weaknesses cast doubt on the company's strategic rationale for extending downstream into heat exchange systems and diesel power unit integration. While management frames this as a natural evolution from component manufacturing to complete system solutions, the timing—amid rising debt and a decelerating core business—raises questions about whether this acquisition serves operational needs or primarily benefits the sellers.
