MACOM Technology Solutions Holdings Inc (NASDAQ: MTSI) is a semiconductor company that designs, develops, and manufactures analog and mixed-signal semiconductor products for the Industrial and Defense, Data Center, and Telecommunications industries. Revenue is transactional, generated through sales of standard and custom devices including ICs, multi-chip modules, diodes, amplifiers, switches, passive and active components, and RF and optical subsystems to over 6,000 end customers (as of FY2025 10-K filing). Headquartered in Lowell, Massachusetts, and incorporated in Delaware in March 2009, MTSI operates fabrication, assembly, and test facilities across North America, Europe, and Asia. The company draws on more than 70 years of application expertise in compound semiconductor fabrication using GaAs, GaN, InP, and specialized silicon processes. FY2025 revenue was $967.3 million, up from $729.6 million in FY2024 and $648.4 million in FY2023.

Revenue model

Transactional product sales of standard and custom semiconductor devices across three end markets: Industrial and Defense (I&D), Data Center, and Telecom. Products are electronic components incorporated into larger customer systems.

Products and services

Integrated circuits (ICs), multi-chip modules (MCMs), diodes, amplifiers, switches and switch limiters, passive and active components, RF subsystems, and optical subsystems. Process technologies include GaAs, GaN, InP, and specialized silicon. Specific product categories include low noise amplifiers, power amplifiers, HMICs, MMICs, optoelectronic and photonic components for 800G, 1.6T, and 3.2T optical interconnects, and non-magnetic diode products for MRI systems.

Customers and end markets

Over 6,000 end customers served across three primary markets (as of FY2025 10-K). I&D end market includes military and commercial radar, RF jammers, electronic countermeasures, communication data links, space and satellite electronics, industrial automation, medical imaging, and test and measurement. Data Center end market addresses AI, machine learning, and high-performance computing applications requiring high-speed optical interconnects. Telecom end market includes 5G deployments, optical network expansion, and wireless basestations.

Value-chain role

Fabless-adjacent semiconductor manufacturer. MTSI designs and manufactures internally using proprietary compound semiconductor fabrication lines and also utilizes external foundries for additional process technologies and capacity. Products are components sold to OEMs and system integrators who incorporate them into larger electronic systems.

Geographic exposure

Headquartered in Lowell, Massachusetts. Operational facilities across North America, Europe, and Asia. Products sold inside and outside the U.S. and subject to U.S. Export Administration Regulations, EU Dual-Use Regulation, ITAR, and French Defense Code.
