Cleanroom Engineering Investment Opportunity Summary Industry Overview - The cleanroom engineering sector is experiencing explosive demand driven by the surge in AI computing power requirements, particularly in advanced process chips, advanced packaging, PCB, and server assembly fields. Data center investments are expected to grow significantly in the coming years [1][2] - The decoupling between China and the US is accelerating capacity transfer, with Taiwanese enterprises relocating to Southeast Asia, further stimulating cleanroom engineering demand, especially in emerging markets like the US and Southeast Asia, which are facing severe labor shortages [1][2] Key Insights and Arguments - Cleanroom investment density per unit area is increasing as production precision requirements rise. The demand for cleanroom construction is driven by risk aversion due to US-China decoupling and the need for AI computing power [1][5] - The electronics industry is the primary contributor to cleanroom demand, accounting for 70%-80%. In capital expenditures for chip wafer fabs, engineering costs represent 20%, with cleanroom systems making up 60% of that [1][7] - The cleanroom industry has high barriers to entry due to complex technology and high customization, leading to deep binding relationships between clients and service providers. Taiwanese service providers are benefiting from the trend of overseas factory construction [1][10] Market Dynamics - The cleanroom engineering sector has shown strong performance this year, driven by changes in both demand and supply. The global demand for AI infrastructure has surged, leading to significant growth in cleanroom engineering [3][4] - The US and Southeast Asia cleanroom markets are in a developing phase, facing severe labor shortages, which has allowed engineering service providers to increase their prices and improve profit margins [4][14] - Despite significant price increases in major stocks, there remains investment potential due to the ongoing demand for higher production cleanliness and the need for new capacity construction driven by AI computing and supply chain security [5][18] Future Growth Sources - The macro trend indicates that smaller process nodes correspond to higher production precision requirements, leading to increased investment density per unit area. The two main short- to medium-term drivers are risk aversion and AI computing demand [8] - The semiconductor self-sufficiency rate in mainland China has room for improvement, and the ongoing relocation of foreign capital will continue to drive market growth. For instance, the cleanroom construction market in mainland China is approximately 50 billion yuan, with potential investments of about 900 billion yuan if Taiwanese companies fully relocate to Southeast Asia [5][8] Competitive Landscape - The cleanroom engineering market can be divided into three tiers, with the first tier serving chip packaging, PCB, precision manufacturing, and data centers. The competition is intense, especially in mainland China, which is transitioning from an emerging to a mature market [11][12] - Key players in the cleanroom engineering sector include Shenghui Integration and Yaxiang Integration, which are positioned to benefit from orders related to factory construction in the US and Southeast Asia [10][15] Investment Recommendations - Focus on companies that can enter emerging markets like the US and Southeast Asia. Shenghui Integration and Yaxiang Integration are highlighted as key investment targets due to their shared technology and customer resources with their Taiwanese parent companies [15][16] - Shenghui Integration is expected to see significant revenue growth starting in 2026, while Yaxiang Integration has already secured multiple major orders and is expanding its business into Southeast Asia [16][18]
