MACOM’s fourth quarter was marked by robust revenue growth and a positive market reaction, driven primarily by strength across its core end markets. Management attributed the strong performance to a surge in demand for data center products, particularly in high-speed optical modules and cables, and highlighted sequential growth in industrial and defense as well as telecom. CEO Stephen Daly emphasized that “data center revenue growth is robust, primarily in pluggable optical modules and optical cables with our 800G and 1.6T PAM4 products,” while also noting record-level backlog and increased bookings, which reflect durable customer demand and execution across all business lines.

Our Top 5 Analyst Questions From MACOM’s Q4 Earnings Call

Vivek Arya (Bank of America Securities) inquired about share gains in telecom following a competitor’s exit and the impact of mix shift on gross margins.
