Performance Analysis
MACOM delivered record quarterly revenue, supported by broad-based growth across industrial and defense, data center, and telecom segments. The company’s industrial and defense (IND) segment led with a 10% sequential increase, driven primarily by defense electronics and electronic warfare, now representing roughly 65% of IND revenue. Data center revenue grew 5% sequentially, with management highlighting a 48% year-over-year surge, underpinned by high-performance connectivity ICs and the successful ramp of 200G photodetectors and LPO (linear pluggable optics) chipsets. Telecom also posted a 4% sequential increase, though management guided for a slight decline in Q4, noting this as “noise level” rather than a structural shift.
Gross margin held steady despite the early RTP fab conveyance, which management flagged as a 60 basis point, $1.5 million near-term headwind. Operating income and EPS continued to climb, reflecting ongoing cost discipline and operational improvements. Cash flow from operations was robust, and inventory turns improved, reflecting both strong demand and prudent working capital management. Notably, MACOM’s Q3 book-to-bill exceeded 1.1, driving record backlog and underpinning management’s confidence in future quarters.
- Segment Revenue Diversification: Data center, IND, and telecom all contributed to sequential and year-over-year revenue growth, with data center now the fastest-growing segment.
- Operational Cash Generation: Cash from operations exceeded $60 million, supporting a net cash position of $235 million even after planned note repayments.
- Inventory and CapEx Discipline: Inventory build supports future programs, while targeted capex at RTP fab aims to boost output by 30% within 12–15 months.
Management’s commentary and Q&A confirmed that secular demand drivers—AI data center buildouts, defense modernization, and 5G infrastructure—remain intact, with product pipeline and customer wins supporting multi-year growth visibility.
Executive Commentary
"Our strategy is to enable the highest power, highest frequency, and highest data rate applications within our three core markets, using proprietary semiconductor processes, IC design techniques, and package technologies."
Steve Daly, President and CEO
"We are excited to have eliminated the business risks of not having the important [RTP] facility under our operational control. With the facility now under MACOM's control, we believe we will be able to increase the speed of improvements to the FAB's production capacity and yields, which will help to stabilize and improve the FAB's performance as we enter fiscal year 2026."
