MACOM posted strong fiscal second quarter 2026 results, driven by continued momentum in data center and optical semiconductor demand tied to AI infrastructure deployments. Revenue reached $289.0 million for the quarter ended April 3, 2026, up 22.5% year-over-year and 6.4% sequentially, while adjusted earnings per diluted share climbed to $1.09 from $0.85 a year earlier. The company also expanded profitability, with adjusted gross margin increasing to 58.5%.
The semiconductor supplier, which serves data center, telecom, industrial, and defense markets, pointed to accelerating growth expectations for the second half of fiscal 2026. MACOM forecast fiscal third quarter revenue between $331 million and $339 million, implying another significant sequential increase. The company also expects adjusted gross margin to rise further to between 59.0% and 60.0%, reflecting favorable product mix and stronger utilization tied to high-speed optical and connectivity demand.
MACOM has become an increasingly important supplier of analog, RF, microwave, and optical semiconductor components used in AI clusters, coherent optical systems, and high-speed interconnect platforms. The company’s portfolio includes technologies supporting 800G and emerging 1.6T optical networking architectures, PAM4 DSP ecosystems, laser drivers, TIAs, and silicon photonics-related infrastructure. As hyperscalers expand AI data center deployments, suppliers of optical and mixed-signal connectivity silicon continue to benefit from rising bandwidth and power-efficiency requirements across scale-out network fabrics.

🌐 Analysis: MACOM’s guidance underscores the continued strength of AI infrastructure spending across optical networking and data center interconnect markets. The company sits in a favorable position within the AI supply chain because many of its analog and optical semiconductor products are critical for scaling bandwidth inside GPU clusters and across data center fabrics. Rising demand for 800G optics, coherent DSP ecosystems, and emerging 1.6T architectures continues to lift suppliers with exposure to high-speed optical connectivity.
🌐 The broader semiconductor ecosystem has recently shown similar momentum. Companies including Coherent, Lumentum, Fabrinet, and Applied Optoelectronics have all highlighted accelerating AI-related optical demand, while NVIDIA and hyperscalers continue expanding investment in Ethernet-based AI networking fabrics. MACOM’s improving margins and raised outlook suggest that AI infrastructure spending remains resilient despite broader macroeconomic uncertainty.
