Single Stock ReportEquitiesInformation Technology

WinWay is expanding its presence in the CPO ecosystem, offering testing solutions from wafer-level to module-level. Goldman Sachs reiterates a Buy rating with a NT$15,000 price target based on accelerating growth from AI chip complexity.

Key Takeaways

  • 1.Co-Packaged Optics (CPO) introduces complex testing requirements across wafer, die, package, and module levels, creating multiple layers of incremental demand for WinWay.
  • 2.WinWay's HyperSocket architecture is uniquely positioned to handle the mechanical, thermal, and electrical challenges of large-scale CPO packages (up to 200mm x 200mm).
  • 3.The investment thesis for WinWay remains strong with a reiterated Buy rating, driven by dollar content expansion in next-gen AI chips and market share gains in the US AI GPU/ASIC markets.
