MACOM Technology Solutions Holdings (MTSI) is back on investor radars after analysts highlighted its role in AI data center optics, along with new PCIe 7.0 products and high speed connectivity demos at OFC 2026.

The recent analyst attention around MACOM’s AI data center exposure, combined with its PCIe 7.0 launches and OFC 2026 product showcases, comes after a mixed patch for the shares. The stock has recorded a 7 day share price return of 4.96% following a 30 day share price decline of 10.8%, while sitting on a 24.25% 90 day share price return and a 1 year total shareholder return of 99.69%. This indicates that momentum has been building over the longer term despite short term volatility.

With MACOM shares up 99.69% over the past year and trading at US$217.80, while sitting about 20% below the average analyst price target of US$261.14, is there still a reasonable entry point here, or is future growth already priced in?
