MTSI - MACOM Technology Solutions Hold

MACOM Technology Solutions designs and manufactures radio frequency (RF), microwave, millimeter-wave, and photonic semiconductor components and modules — including power amplifiers, diodes, and integrated circuits — sold under the MACOM brand. The core customer base is defense contractors, telecom equipment OEMs, and data center infrastructure builders, with a fabless-plus-owned-fab hybrid model selling components through direct sales and distribution. Annual revenue is approximately $700-750 million, with significant exposure to North American defense and global telecom markets. Defense and industrial applications represent roughly half of revenue, with data center and telecom comprising most of the remainder.

Past Year Trends

• MACOM reported record FY2025 revenue of $967 million, representing 32% year-over-year growth, with the Data Center segment surging 48% to $293 million as AI infrastructure buildout drove demand for 800G and 1.6T optical components. (Bullish)
• MACOM crossed the $1 billion annualized revenue run rate in Q1 FY2026 ($271.6M, +24.5% YoY) and posted Q2 FY2026 revenue of $289M (+22.5% YoY), with adjusted EPS rising from $0.43 to $0.62 quarter-over-quarter as operating leverage improved. (Bullish)
• MACOM secured photodetector design wins at all major optical module manufacturers supporting 800G and 1.6T Linear Pluggable Optics (LPO) platforms, establishing the company as a critical supplier in the ratified LPO standard architecture for AI data center interconnects. (Bullish)

Next Year Trends

• MACOM guided Q3 FY2026 revenue of $331–$339 million (~22% YoY at midpoint), driven by accelerating adoption of near-packaged optics (NPO) and LPO solutions at hyperscaler AI clusters, representing a product-cycle ramp that management has cited as a multi-year volume step-up. (Bullish)
• The Industrial and Defense segment (~43% of total revenue) faces execution risk tied to U.S. defense budget resolutions and potential continuing resolutions in FY2027; any slowdown in radar, electronic warfare, or communications program spending would directly pressure roughly $400M of MACOM's annual revenue base. (Bearish)
• MACOM's revenue is concentrated among a small number of hyperscaler-aligned optical module manufacturers adopting 800G/1.6T platforms; a shift by major cloud customers back toward DSP-based optics or a slowdown in AI CapEx would reduce demand for MACOM's LPO components with limited near-term offset from other segments.
