护城河
护城河: 最新变动 2026-04-17 Tongfu is the world's fourth-largest OSAT and AMD's main packager. It owns 85% of the former AMD assembly and test plants in Suzhou and Penang, and it runs plants in Nantong, Hefei and Xiamen, nine production bases in all. The AMD joint ventures handle the majority of AMD's assembly and test, per AMD's 10-K. Tongfu says it supplies more than 80% of AMD's related products, which is the company's own figure. Revenue in 2025 was RMB 27.92 billion, up 16.92%, and 66.59% came from outside China. Net profit attributable to shareholders rose 79.86% to RMB 1.219 billion. Outside AMD, growth comes from Chinese chip designers: domestic revenue rose more than 20% in 2025 as the company seized the window for localizing analog chips. It also cites PMIC share gains, two leading display-driver customers and a doubled automotive customer count. Domestic revenue rose 45.19% in 1H26. The company is moving up the stack with the VISIONS 2D+ chiplet platform, 3nm multi-chip packaging validated at Penang, work on 2nm, and co-packaged optics that it says passed reliability testing. In 1H26 revenue rose 23.03% to RMB 16.04 billion, and net profit attributable rose 316.77% to RMB 1.717 billion. More than half of that half's total profit came from fair-value gains. For 2026 the company targets revenue of RMB 32.3 billion and plans RMB 9.1 billion of investment. The verdict is no moat: Tongfu is a dependable, growing captive packager whose AMD tie secures volume but not margin.

The AMD relationship anchors Tongfu's volume, but its returns are thin. The 2025 annual report gives weighted average ROE of 8.08%, or 5.57% excluding non-recurring items. Net profit attributable to shareholders was RMB 169 million in 2023, RMB 678 million in 2024 and RMB 1.219 billion in 2025. Excluding non-recurring items, it was RMB 59 million, RMB 621 million and RMB 841 million. Packaging and test gross margin was 14.40% in 2025, down 0.10 points, even though revenue rose 16.92% and utilization improved. The 1H26 report shows ROE of 10.54% for the half, but only 4.59% excluding non-recurring items. Fair-value gains of RMB 1.145 billion made up 53.56% of total profit in that half, and the company marks them as not sustainable.

The nearest candidate is switching costs around AMD, but that lock-in cuts both ways and has not lifted margins. AMD's FY2025 10-K says it is party to two ATMP joint ventures with affiliates of Tongfu, and that 'the majority of our ATMP services are provided by the ATMP JVs'. The same filing names SPIL and KYEC as ATMP providers too, and warns there is 'no guarantee that the ATMP JVs will be able to fulfill our long-term ATMP requirements'. One unnamed customer took 52.29% of Tongfu's 2025 revenue, and the top five took 69.54%. Management's own goodwill test for the TF-AMD Suzhou and Penang group assumes gross margin of 13.48% in 2026, rising to 18.62% in 2028. Cost scale: TrendForce ranks Tongfu fourth at $3.32B in 2024, against ASE's $18.54B. IP: the company says it entered key packaging fields through technology licences from Fujitsu, Casio and AMD. TrendForce (2026-01-19, citing Jiemian News) says the four projects in its RMB 4.4 billion placement 'primarily involve expanding capacity based on existing process technologies, with little focus on new technology development'.
领先地位: 势均力敌
TrendForce's 2024 ranking (2025-05-13) says 'Fourth-ranked Tongfu Microelectronics recorded $3.32B in revenue (+5.6% YoY)' and that 'a strong performance from key customer AMD also supported revenue stability'. In the same ranking, JCET recorded $5B, Amkor $6.32B and ASE $18.54B. TrendForce (2026-01-19) describes Tongfu's goal as solidifying 'its standing as the world's fourth-largest and China's second-largest player'. The 2025 annual report, citing ChipInsights, says its global top-ten rank was unchanged. The company says it is keeping pace with AMD's process nodes, but that is its own claim: the 2025 report says 3nm multi-chip packaging passed validation at Penang, and the 1H26 report says the plants are now working on the 2nm node.

Packaging and test gross margin was 14.40% in 2025, down 0.10 points, even as revenue rose 16.92% and the company cited higher utilization. It was 15.12% in 1H26, up 0.73 points. The risk section says weak demand and intense product competition 'will affect product prices'. It also says the main raw materials for high-end packaging are mostly imported. Management's goodwill test assumes a 13.48% gross margin for the TF-AMD Suzhou and Penang group in 2026.
