What could break the thesis?
The concentration worsened. Communications revenue increased 81% in 2025 and represented 57% of total revenue, while Enterprise revenue fell 19% because of a technology transition in one hyperscaler AI/ML program. CCS margin improved from 6.2% in 2023 to 7.4% in 2024 and 8.2% in 2025, so the risk had not yet harmed margins, but the revenue mix became substantially more dependent on one fast-growing end market. The Jun. 2026 baseline confirms the exposure remained high. (2 intensifying)
“Communications end market revenue for 2025 increased $3,179.7 million (81%) compared to 2024 ... Enterprise end market revenue for 2025 decreased $481.7 million (19%) compared to 2024, driven by the technology transition in an AI/ML compute program with one of our hyperscaler customers.”
