Thesis Summary

MACOM entered the final quarter of fiscal 2026 with strong operating momentum: fiscal Q3 revenue increased 35.8% year over year, adjusted operating margin reached 31.5%, and management guided fiscal Q4 revenue to USD 415-425 million with a 60.0%-61.0% adjusted gross margin. Data Center revenue increased 81.5% year over year and Industrial & Defense revenue increased 23.3%, while the completed IQE investment and long-term supply agreements are intended to reinforce epitaxial supply. The evidence supports a favorable operating outlook, but customer concentration.

Bear CaseDownside scenario
$300.0020%

Fiscal Q4 revenue or adjusted gross margin falls below guidance as customer concentration, trade restrictions, demand volatility or product-mix changes offset Data Center and defense momentum. Rising inventories would increase the consequences of any demand correction.

Base CaseCentral scenario
$399.6456%
Matches the consensus mean

MACOM delivers within its fiscal Q4 revenue and adjusted gross-margin guidance ranges, with Data Center and defense demand remaining the principal growth engines while Telecom grows more moderately.

Bull CaseUpside scenario
$475.0024%

MACOM meets or exceeds the top of its fiscal Q4 guidance, sustains rapid optical Data Center growth, and converts the higher-volume product mix into adjusted gross margin above 61%. Continued Industrial & Defense growth and improved supply resilience from the IQE agreements reinforce the expansion.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.

Key Investment Merits

Key Investment Risks
  • Customer concentration is material: Customer A represented 23% and Customer C represented 13% of fiscal Q3 revenue, while the top ten customers represented 60%.
  • China represented USD 133.8 million of fiscal Q3 revenue, creating exposure to tariffs, sanctions, licensing requirements and other trade restrictions.
  • Inventory increased to USD 281.5 million at July 3, 2026 from USD 237.8 million at October 3, 2025, increasing execution risk if demand weakens.
