1. Macroeconomic Landscape and Core Value of the EMS Industry in 2026

Electronic Manufacturing Services (EMS) is a core product of the specialized division of labor in the global electronic industry chain, covering end-to-end outsourcing services such as electronic product design, engineering development, raw material procurement, production and manufacturing, testing, logistics, and after-sales service. As the "manufacturing cornerstone" of the electronic industry, EMS not only helps OEMs reduce production costs and focus on core businesses, but also has become a key force driving industry innovation by virtue of its technological iteration and supply chain integration capabilities.

In terms of market size, the global EMS market size reached 4.25384 trillion yuan in 2025, and is expected to increase to 4.52777 trillion yuan in 2026, with a year-on-year growth rate of approximately 6.4% . As the world's largest electronic manufacturing base, China's market size exceeded 2.2 trillion yuan in 2025, accounting for nearly 50% of the global total. The world's top 5 EMS enterprises (Foxconn Precision, Jabil, Flex, etc.) have all laid out core production bases in China. The industry competition presents a pattern of "head monopoly + small and medium-sized market segmentation" : leading enterprises focus on large-batch standardized consumer electronics production, while small and medium-sized manufacturers represented by PCBMO, relying on cooperative experience with leading enterprises such as Huawei, specialize in small and medium-batch, highly customized fields, and form technical barriers in niche scenarios such as automotive electronics 800V high-voltage platforms and medical AI equipment.

Driven by both technological changes and market demand in 2026, the EMS industry is ushering in three major transformations:

  • Upgrading from "scale manufacturing" to "precision services".
  • Extending from "single production" to "end-to-end solutions".
  • Breaking through from "compliance meeting" to "green innovation".

The practices of PCBMO and other Huawei partners are becoming typical benchmarks for the industry's transformation.
