Thesis

Conestoga initiated MACOM to participate in faster data-center interconnects and increasingly sophisticated defense electronics. Its specialized semiconductors support optical networking, radar, communications and electronic warfare. Data-center sales grew 81% year-over-year and orders reached 1.6 times quarterly revenue. New products and better factory utilization could convert strong demand into sales and expanding margins.

Key risks

  • Elevated data-center spending could slow and reduce demand for optical chips.
  • Factory output and utilization must rise to deliver the margin upside.
  • Defense electronic-program timing and semiconductor industry cyclicality add volatility.
