Recently, A-share ChiNext semiconductor testing equipment leader Hangzhou Changchuan Technology Co.,Ltd. (300604.SZ) announced plans to issue H shares and list on the Main Board of the Hong Kong Stock Exchange. The company stated that the H-share listing is intended to advance its global strategic layout, accelerate overseas business expansion, strengthen capital strength and overall competitiveness, and establish an international capital operations platform. As of now, core details such as issuance size and pricing have not yet been finalized. The listing still requires approval from the shareholders' meeting and regulatory filings and approvals from the China Securities Regulatory Commission, the Hong Kong Stock Exchange, and other domestic and overseas regulators, leaving the overall process subject to significant uncertainty.

Hangzhou Changchuan Technology Co.,Ltd. (300604.SZ) is a high-profile bull stock in the A-share market. Since August 2025, its share price has climbed steadily, accumulating a gain of approximately 490% to date. Hangzhou Changchuan Technology Co.,Ltd. is a core domestic supplier of integrated circuit testing equipment, providing a full suite of testing equipment to packaging and testing plants, wafer fabrication plants, and chip design companies. Its main products cover testers, sorters, automation equipment, and AOI optical inspection equipment. Its downstream customers include JCET Group, Huatian Technology, Tongfu Microelectronics, Silan Microelectronics, China Resources Microelectronics, and ASE Technology Holding, among other well-known integrated circuit companies at home and abroad. Its customer matrix covers mainstream domestic packaging and testing manufacturers while also reaching into the world's leading packaging and testing clusters.

Benefiting from the explosive growth of the AI computing industry, high-end digital testers have achieved large-scale commercial deployment, and the company's performance has entered a phase of rapid release. In the first half of 2026, the company achieved revenue of 3.461 billion yuan (RMB, same below), a year-on-year increase of 59.7%; net profit attributable to shareholders was 964 million yuan, a sharp year-on-year increase of 125.7%, with profit growth significantly outpacing revenue growth. The strong performance growth stems from the resonance of two major factors: on one hand, the company's high-end product lines such as digital testers, which it had continuously invested in researching and developing, welcomed batch orders in 2025-2026, becoming the core engine of performance growth; on the other hand, revenue scale expansion brought economies of scale, diluting unit production costs and further elevating profitability.

In terms of business structure, testers represent the segment with the highest technical barriers and the largest profit contribution. In the first half of 2026, tester revenue was 1.871 billion yuan, with a gross margin of 64.94%; sorter revenue was 1.158 billion yuan, with a gross margin of 41.44%. Both product categories recorded high double-digit year-on-year revenue growth, together achieving combined revenue of over 3 billion yuan, accounting for nearly 90% of total revenue. Among them, testers, with their higher gross margin, contributed particularly prominently to profit growth.

Technology research and development is the foundation of semiconductor equipment companies. As of the end of June 2026, Hangzhou Changchuan Technology Co.,Ltd. held more than 1,600 patents domestically and overseas. In the first half of 2026, R&D investment as a proportion of revenue reached 21.99%, maintaining high-intensity R&D investment and continuously extending into higher-difficulty tracks such as SoC testers and memory testers, benchmarking against the technical capabilities of leading overseas manufacturers. High R&D investment opens up import substitution space for the company, but the high-end testing equipment track has long been dominated by international giants. New product certification and introduction still require relatively long cycles, and pressure from technological iteration persists.

While the AI industry's high prosperity drives order prosperity, the market also needs to objectively view the operational risks the company faces. First is the strong cyclical nature of the industry. Semiconductor equipment orders are highly tied to downstream manufacturers' capital expenditures. If the current AI-driven industry prosperity declines and downstream expansion pace slows, it will directly affect the delivery pace of equipment orders. Second, as of the end of June 2026, the company's accounts receivable reached 2.269 billion yuan, significantly higher than its net profit for the period. The accounts receivable-to-net profit ratio is high, with substantial funds tied up on the downstream customer side. Semiconductor equipment adopts a revenue recognition model based on acceptance, and packaging and testing customers have long acceptance cycles. If downstream packaging and testing plants contract capital expenditures or come under operational pressure, delayed payments or even bad debt provisions may occur, directly impacting profits and operating cash flow.

Overall, Hangzhou Changchuan Technology Co.,Ltd. is in a golden window for domestic testing equipment substitution. High-end SoC testers have already achieved breakthroughs, and performance has been validated by downstream demand. However, investors still need to view this H-share IPO rationally, recognizing both the growth opportunities brought by the AI computing wave and the potential risks including industry cyclical fluctuations, high-base growth pressure, overseas expansion falling short of expectations, and new product commercialization progress falling short of expectations. The subsequent finalization of the H-share issuance plan, regulatory approval progress, and overseas customer development results will be key signals for observing the globalization credentials of this domestic testing equipment leader.
