MACOM Technology Solutions Holdings, Inc. (MTSI) Business Profile

What it does

MACOM Technology Solutions Holdings designs, develops and manufactures semiconductor components that customers build into larger electronic systems. Its products handle radio-frequency, microwave and optical signals in equipment such as radar, satellite networks, wireless base stations and data center networks. MACOM traces its roots to 1950, is headquartered in Lowell, Massachusetts, and is led by President and Chief Executive Officer Steve Daly.

The company serves three primary markets: industrial and defense, data centers, and telecommunications. Industrial and defense applications range from military radar and communications to medical imaging and scientific equipment. In data centers, MACOM supplies components for optical connections that move data between computing equipment. In telecom, its products are used in wired and wireless communications infrastructure, including satellite systems.

Its catalog includes standard and custom integrated circuits, amplifiers, switches, diodes, lasers and optical components. Customers can use individual parts or, in some cases, components designed to work together as a chipset. MACOM also supplies modules and subsystems that combine components into assemblies.

The company designs circuits and develops semiconductor processes and packaging. It makes some products in its own facilities and uses outside manufacturers for additional technologies and capacity. It had approximately 2,000 employees worldwide as of October 3, 2025.

How it makes money

MACOM earns revenue by selling semiconductor products and solutions. It has one reportable operating segment, although it discusses demand across its industrial and defense, data center, and telecom markets. Products are sold directly and through independent sales representatives, resellers and distributors.

In industrial and defense, MACOM sells components for radar, military communications and other systems, as well as industrial, medical and test equipment. Its data center products include amplifiers, drivers, lasers and photodetectors used in optical transceivers. Telecom customers buy components for applications including wireless infrastructure, satellite communications and fiber-optic networks. Some products can serve more than one market: for example, power amplifier technology is used in both scientific equipment and radar.

Sales are primarily made through purchase orders rather than long-term agreements requiring customers to buy a minimum quantity. MACOM also ships some products shortly after receiving an order from inventory. Certain products have long life cycles and continue to generate sales over many years, although others have shorter lives. Sales therefore can recur as customers order components for their systems, but customers do not generally commit to a minimum purchase over an extended period.

Prices can decline over a product’s life. MACOM seeks to offset price erosion by introducing products that cost less to manufacture or command higher prices through their performance. Revenue and margins also depend on product mix, manufacturing yields, facility utilization and material costs.

Fiscal 2025 revenue was $967.3 million, compared with $729.6 million in fiscal 2024. Fiscal 2025 included 53 weeks, while fiscal 2024 had 52 weeks.

Customers and how it sells

MACOM serves equipment manufacturers, contract manufacturers, resellers and distributors. Its components reach over 6,000 end customers across its three primary markets. Application engineers work with customers at their engineering and manufacturing sites, helping them evaluate products and incorporate components into their systems.

The company sells through its own sales force and application engineers, as well as independent representatives, resellers and distributors. Distributor sales accounted for 32.3% of revenue in fiscal 2025. Sales are principally made in North America, Asia and Europe, where MACOM concentrates its sales and support resources.

The top ten customers accounted for 57.0% of fiscal 2025 revenue. Two customers, identified as Customer A and Customer B, accounted for 12.0% and 11.0%, respectively. No direct customer individually accounted for 10% or more of revenue in that year; the customer base also includes resellers and distributors.

The United States accounted for 43.7% of fiscal 2025 revenue, and China accounted for 28.4%. Asia Pacific excluding China contributed 11.5%, and other countries contributed 16.4%. MACOM says it has no manufacturing in China and that most products it sells into China are exported from the country as part of systems, typically destined for the United States.

Suppliers and costs

MACOM combines its own wafer fabrication, assembly and testing facilities with external foundries and contractors. Its fabrication sites are in Massachusetts, North Carolina, Michigan and France. Outside partners provide access to other manufacturing processes and capacity, and can also perform assembly, packaging, testing or complete production.

The company buys wafers, packages, metals, circuit boards and other materials from hundreds of suppliers. No individual supplier is named for those purchases. Some materials and components are not readily available from alternative suppliers. Wafers for a particular external process are generally sourced from a single foundry, making that process dependent on the foundry’s continued supply. MACOM seeks alternative sources where practical and may redesign products or hold additional inventory.

Manufacturing costs include materials, labor and the fixed costs of operating facilities. Low utilization can leave those fixed costs spread over fewer units, raising unit costs and reducing gross margin. Research and development is another expense: it was $244.5 million in fiscal 2025, representing 25.3% of revenue. Fiscal 2025 gross margin was 54.7%.

Competitive position

MACOM competes with customers’ internal design teams and with other suppliers of analog semiconductors used in wireless, wireline and optical applications. Named competitors include Analog Devices, Broadcom, Credo, Marvell, MaxLinear, Microchip, NXP, Qorvo, Semtech, Skyworks and Sumitomo. Some competitors are also customers, and some provide foundry services to MACOM. Competition turns on product performance, reliability, price, supply, technical support and the ability to develop new products.

MACOM combines circuit design, semiconductor process technology, packaging and system-level expertise. Its engineers work with customers during system design, and some products remain in use for many years. Its Lowell fabrication facility has U.S. Department of Defense Trusted Foundry accreditation; domestic fabrication can be a requirement for a strategic supplier in industrial and defense markets.

Our reading: Design and application expertise can support durable customer relationships, but winning a design does not guarantee a production order and customers may also develop products internally. Our reading: Trusted Foundry accreditation and domestic fabrication provide a more specific advantage where customers require a secure domestic supply chain, although that advantage does not apply equally across all markets. Our reading: MACOM’s internal and external manufacturing options broaden its process choices, but reliance on outside foundries limits its control over supply.

Growth opportunities

MACOM’s strategy is to expand its product portfolio and addressable markets, strengthen customer relationships and win more product designs. It also seeks to sell more of its components into customers’ systems and uses acquisitions to add technologies and capabilities.

In fiscal 2025, data center revenue increased by 48.0%, driven primarily by higher sales of analog and coherent products supporting high-speed data rates. Industrial and defense revenue increased by 19.4%, and telecom revenue increased by 41.4%. The company expects faster data center connections and upgrades to optical networks to support demand for its components. It also expects an expanded product portfolio to support industrial and defense revenue and communications infrastructure deployments to support telecom revenue.

MACOM says its data center growth is driven by U.S. hyperscalers and enterprise and computing equipment manufacturers. It has active development projects for near-package optics, where customers need smaller, lower-power components with more channels. The company expects some related revenue to begin in 2028, while acknowledging that some projects may not reach production.

In satellite communications, MACOM expects several low-Earth-orbit programs to begin production around the end of the calendar year and the beginning of the next. It also sees an opportunity to win more business in 5G massive MIMO systems using its GaN technology. The company sizes its serviceable markets in industrial and defense and data centers at approximately $6 billion each.

Structural risks

• Industry cycles and technology shifts. Semiconductor demand and supply fluctuate, while products can become obsolete and selling prices can decline. A slowdown in data center infrastructure spending could reduce demand for MACOM’s products.
• Product development and design wins. Maintaining revenue depends on developing products that meet customer requirements. Design and qualification can take a long time, and even a successful design win may not result in volume purchases.
• Customer orders and inventory. Customers generally buy through purchase orders and can often cancel or defer shipments. Inaccurate demand forecasts can leave MACOM with excess inventory and write-downs, or with insufficient supply to fill orders.
• Manufacturing and supply. Some process-specific wafers come from a single foundry. Supplier capacity constraints, closures or discontinued processes could disrupt supply; underused internal facilities can also raise unit costs and reduce gross margin.
• Customer and international exposure. A limited number of customers account for a significant share of revenue. Sales outside the United States expose MACOM to trade restrictions, export licensing requirements and geopolitical disruption, including changes affecting China.
• Product quality. Complex products operate in demanding environments, and defects can lead to returns, claims, lost orders and reputational damage. Less mature semiconductor processes can have less extensive field-reliability records.

Bottom line

Our reading

MACOM is a component supplier whose business rests on analog and optical design expertise, customer engineering relationships and a combination of internal and outsourced manufacturing. Its opportunities span defense electronics, faster data center connections and communications networks, but converting design work into production sales can take time. Revenue is exposed to concentrated customer orders, semiconductor cycles and supply constraints, while the costs of operating fabrication facilities make utilization relevant to margins.
