StockStory’s take

MACOM’s third quarter performance featured strong year-on-year sales growth across all major end markets, with data center and industrial & defense segments achieving record revenue levels. Despite exceeding Wall Street expectations for revenue and non-GAAP profit, the market response was notably negative. Management attributed the quarter’s results to accelerated production capacity, a robust backlog, and new high-margin product introductions, while acknowledging ongoing cost pressures in materials, labor, and energy. CFO Jack Kober cited improved factory utilization and efficiency gains as key contributors to margin expansion, while CEO Steve Daly credited “meaningful progress improving the quality of our indium phosphide lasers” as a driver for future growth.

Looking ahead, MACOM’s guidance reflects management’s confidence in continued demand from hyperscale data center customers and defense programs. Steve Daly, President and CEO, emphasized the company’s investments in R&D and manufacturing expansion, stating, “We believe these activities will enable MACOM to provide our new and compelling products at scale and meet our customers' growing demand during 2027 and 2028.” Management remains focused on scaling production capacity, advancing new product lines such as CW lasers and near-packaged optics, and maintaining margin discipline, though they acknowledged execution risks and ongoing supply chain challenges.

Key insights from management’s remarks

Management highlighted growth in data center and industrial & defense, improved product mix, and expanding production capacity as central themes, while also addressing operational efficiencies and strategic investments for longer-term competitiveness.

• Data center momentum: Management reported significant sequential and year-over-year growth in the data center segment, attributing it to increasing adoption of high-speed analog products for next-generation optical modules, especially for AI infrastructure. Steve Daly emphasized the company’s “strong position in the market,” citing increased 1.6T volumes and content expansion as drivers.
• Industrial & defense strength: The industrial and defense segment saw record revenue, supported by expanding U.S. and European defense budgets and new wins in advanced radar, electronic warfare, and drone systems. MACOM’s unique semiconductor processes and custom solutions were highlighted as key differentiators, resulting in new long-term development programs with major defense contractors.
• Telecom and SATCOM opportunity: Telecom revenue grew due to demand in 5G and SATCOM markets, with a notable focus on low Earth orbit (LEO) satellite ground station products. Daly described a recent customer contract in LEO as a “$20 million new business opportunity beginning in early 2028.”
• Manufacturing expansion and efficiency: The company continued to invest in expanding capacity at three wafer fabs and two U.S. manufacturing sites, aiming to support future growth. Efforts included upgrades to millimeter wave GaN processes and migration to larger wafer sizes in France, driving operational efficiency and product quality improvements.
• Product development and R&D focus: MACOM increased R&D spending, including the use of AI in design processes, to accelerate new product introductions. Breakthroughs in indium phosphide laser technology were cited as opening new addressable markets, with Daly describing “recently made significant technology improvements” that enhance reliability and performance for future applications.

Drivers of future performance

MACOM’s forward outlook is driven by anticipated growth in data center demand, continued defense investment, and scaling of new product introductions, though management noted execution and supply chain risks.

• Data center expansion: Management expects growth in high-speed analog and photonics products to continue, fueled by hyperscaler investments in AI and next-generation optical architectures like near-packaged optics. Daly indicated that customer demand for 200G and 400G products, as well as early-stage NPO revenue, will be important contributors in the coming year.
• Capacity and supply chain management: MACOM is scaling manufacturing capacity, including targeted capital expenditures and backend infrastructure upgrades. The company is actively managing relationships with external foundries to secure needed wafer supply, while leveraging government programs like the CHIPS Act to support U.S. fab expansion.
• Margin progression and cost risks: Management aims to maintain or expand operating margins by improving product mix and operational efficiencies, but cautioned that higher R&D spending, inflationary pressures, and uncertainties in customer order timing—particularly in telecom—could create volatility in quarterly results.

Catalysts in upcoming quarters

Looking ahead, the StockStory team will monitor (1) the rollout and customer adoption of new high-speed optical and photonic products in data centers, (2) the pace and effectiveness of capacity expansion at U.S. and international fabs, and (3) successful execution of long-term defense and LEO satellite contracts. Additional focus will be on margin sustainability amid rising R&D and operational costs, and on the ability to secure supply chain commitments for critical components.

MACOM currently trades at $192.01, down from $233.41 just before the earnings. At this price, is it a buy or sell? Find out in our full research report (it’s free).
