ON Semiconductor: Customer Map and Commercial Leverage

ON Semiconductor (ON) designs and sells power and analog semiconductors to OEMs, distributors and system integrators across automotive, industrial, energy and medical markets. The company monetizes through product sales under a mix of long‑term supply agreements and short‑term distributor channels, with roughly half of revenue routed through distributors and the balance to direct large‑enterprise customers; this dual channeling gives ON both scale and negotiated leverage while concentrating execution risk around a handful of strategic OEM wins.

Why customers define ON’s risk/reward profile

ON’s business is fundamentally a product‑supply model to large manufacturers and system houses. Revenue is driven by design‑wins (which create multi‑year demand) and by distributor throughput (which smooths order timing). The company reports roughly $6.0bn in trailing revenue and a mix of long‑term supply agreements and 30‑day distributor terms, which creates both durable backlog and short‑cycle working capital exposure. Investors should value ON on the basis of (1) the pace of new design wins in high‑growth end markets (EV powertrains, energy storage, industrial AI power); (2) the degree to which revenue is concentrated through a small number of distributors; and (3) gross margin expansion from SiC and next‑generation power products.

What the relationship set implies about ON’s operating model

• Contracting posture: ON balances multi‑year Long‑Term Supply Agreements (LTSAs) — with roughly $7.1bn of remaining performance obligations disclosed as of Dec 31, 2025 — against short‑term distributor terms (many distributor payments within 30 days). This creates revenue durability from design‑wins alongside working capital seasonality.
• Counterparty mix and concentration: The company targets large multinational OEMs and selected regional OEMs; distributors collectively accounted for roughly 54% of revenue in 2025, and one distributor represented ~11% of revenue — a meaningful concentration that affects downside risk.
• Relationship maturity and criticality: ON’s customers are typically large, mature enterprises with renewable supply agreements; design wins translate into multi‑year manufacturing programs, making these relationships both strategic and revenue‑critical.
• Spend scale: ON’s disclosure shows customer spend bands that include $100m+ relationships, reinforcing the materiality of a small number of large contracts to corporate results.
• Role diversity: ON acts as direct seller to OEMs and as a component supplier to distributors, which resell or integrate parts into system‑level solutions — a dual role that supports scale but also transfers execution dependency to distribution partners.

Investment implications and key takeaways

• Upside: Design wins with NIO, Geely, GM and major inverter suppliers demonstrate ON’s leadership in SiC and advanced power platforms — a structural advantage as EV and grid‑scale power demand grows.
• Risk: Revenue concentration via distributors and a handful of large OEM programs amplifies cyclical hit risk; investors must track distributor order patterns and LTSA renewal cadence.
• Operational focus: Margin expansion will depend on scaling SiC and V‑GaN programs into high‑volume automotive and industrial production, and on converting engineering engagements into sustained production revenue.
