Wingtech’s broken arm, Vail’s name change, and the rise of domestic AI chips: six major strategic shifts in the semiconductor industry (2025.5.20)

1. Wingtech Technology: 4.389 billion sold ODM, fully betting on semiconductors

1. Transaction details

• Transaction party: Wingtech Technology → Luxshare Precision and Luxshare Communications
• Target: 100% equity of Kunming Wenxun, Huangshi Zhitong, Shenzhen Wingtech, Hong Kong Wingtech (including Indonesia) + Wuxi Wingtech, India Wingtech business asset package
• Price：4.389 billion yuan(cash)
• time: Announced in May 2025, approved in June
  

2. Strategic significance: ODM → complete transformation of semiconductors

• Exit product integration (ODM/mobile phone/tablet/laptop OEM), the business’s revenue in 202458.4 billion yuan, proportion79%
• core logic: ODM has low profits, large fluctuations, and is affected by geography; semiconductor (Nexperia + Xinxin)High gross profit, high barriers, large room for domestic substitution
• Usage of funds: Added power devices, simulation, automotive chips, advanced packaging

3. Industry impact

• Luxshare: Strengthen ODM/complete machine manufacturing, win Samsung/Xiaomi/OPPO customers
• Wingtech: Revenue dropped significantly,Net profit margin increased significantly, becoming a pure semiconductor company

2. Vail Group → Howe Group: Brand upgrade, strengthening automotive and high-end CIS

1. Name change information

• full name：Shanghai Weir Semiconductor →Haowei Integrated Circuit (Group) Co., Ltd.
• Securities abbreviation: Weir shares →OmniVision Group(603501 unchanged)
• implement: Officially effective on June 20, 2025
  

2. Strategic background

• 2019 AcquisitionsOmniVision, image sensors (CIS) account for revenue75%
• HowieIt is one of the top three automotive/mobile phone CIS manufacturers in the world, and its brand value is higher than that of Weir
• focus：Mobile +Automotive electronics+ Industrial/Medical, work hardAutomotive CIS, SerDes, analog chips

3. Core signals

• Go to distribution and strengthen design: From distributor → GlobalFabless chip design giant
• Groupization and globalization: A+H goes public, hits the high end, and strengthens the automotive supply chain

3. Dramatic changes in the AI chip landscape: China’s domestic share reaches 40%, equally divided with outsourcing

1. Data (TrendForce 2025.5)

• 2024: Outsourced (NVIDIA/AMD)63%, local37%
• 2025: outsourcing42%, local40%(nearly flat)

2. Local camp (core players)

• Huawei Shengteng: Accounting for nearly half of domestic products, adapted to AI training + reasoning
• Cambrian, Haiguang, Pingtou Ge, Kunlun Core, Mu Xi, Tianshu ZhixinWait for quick volume increase

3. Drivers

• Policy + Supply Chain Security：Autonomous and controllable, independent computing power
• AI server outbreak: Domestic chipsCost-effectiveness + customization + service responseAdvantages
• North American CSP self-developed ASIC: Global decentralization, China accelerating self-research

4. TSMC Q1: AI craze, revenue + 41.6%, net profit + 60.3%, capital expenditure of 15.2 billion

1. Financial report highlights (2025Q1)

• revenue: NT$839.25 billion (+41.6%)
• net profit: NT$361.56 billion (+60.3%)
• Gross profit margin：58.8%、EPS 13.94 yuan
• HPC (AI) accounts for 59%(YoY + 82%), mobile phone 28%

2. Capital action

• new capital budget：US$15.2477 billion(approximately 110 billion yuan)
  • 70%: Advanced process (2nm/3nm)
  • 10–20%: Advanced Packaging (CoWoS)
  • 10–20%: mature / special process + factory building
• Full year capital expenditure：US$38-42 billion

3. Impact

• Advanced manufacturing processes continue to be in short supply and prices rise(2nm/4nm price increase 10–30%)
• Domestic replacement window：Mature process (28nm/40nm)Excellent value for money

5. OmniVision Group: Nationalization of automotive SerDes, 2Gbps has been designated, 6Gbps is coming in Q3

1. New product: OTX9211 (serializer) + OTX9342 (deserializer)

• rate：2GbpsOmniVision Group
• Application: Surround view/peripheral view/rear view, DMS/OMS, streaming media rearview mirrorOmniVision Group
• Core advantages
  • National production: Design/Wafer/Full packaging and testing chain independent
  • long range：Coaxial26 meters,STP 10 meters
  • car regulations：AEC-Q100 Grade 2、ASIL-B
  • Single deserializer with 4 camerasOmniVision Group

2. Roadmap

• 2025Q3：6GbpsSerDes, support8 million pixels, C-PHY, AI power management

6. Renesas RZ/A3M: RTOS-MPU with built-in 128MB DDR, greatly simplifying the HMI solution

1. Core specifications

• CPU: 64-bit Cortex-A55 @ 1GHzRenesas
• storage:SiP integration128MB DDR3L+128KB SRAMRenesas
• show: 1280×800, MIPI-DSI, 2D accelerationRenesas
• encapsulation：244-pin LFBGARenesas

2. Industry value

• PCB from 6 layers→2 layers、BOM-18~25%, development cycle - 40%
• scene: Home appliances, industrial HMI, medical, building, office automationRenesas

7. Summary of six major trends

1. Chinese design company strategic focus：Divest low gross profits and focus on high-barrier semiconductors(Wingtech, Weir)
2. Brand upgrade：Vail→Howey, strengthen awareness of high-end and car specifications
3. Domestic replacement of AI computing power accelerates：Local chips 40%, policy + demand two-wheel drive
4. TSMC AI dominates：High growth + high capital expenditures + price increases, the monopoly of advanced processes is strengthened
5. Car chip outbreak：CIS+SerDes+PMICA breakthrough in national production
6. Integration and cost reduction: SiP and single-chip solutions have become mainstream (Renesas RZ/A3M)
