2. Thesis Layer

Primary Secular Thesis: Energy Transition & Electrification (EV Supply Chain) Directness: Tier Direct | Confidence: High

ON Semiconductor is a primary beneficiary of the global electrification of transportation. As of the event date, the company's role is central to the EV supply chain, specifically through its intelligent power technologies that enable electrified drivetrains and efficient fast-charging systems. Management has explicitly stated that higher energy costs are accelerating EV demand, driving the adoption of IGBT-based traction inverter solutions.

Additional Secular Tailwinds:

• AI Infrastructure (Power/Grid): ON is positioned as a second-order beneficiary in AI data centers, where energy efficiency is critical. Management notes that AI data center operators are focused on reducing energy consumption, and ON's intelligent power technologies enable this efficiency.
• Reshoring & Industrial Automation: The company benefits from semiconductor onshoring trends, supporting the broader industrial automation ecosystem.
• Advanced Robotics: While currently a tertiary exposure, ON's Treo-based driver ICs and inductive position sensing are being adopted for humanoid applications, though confidence in this specific tier is currently low compared to the EV thesis.

The convergence of these themes, particularly the direct exposure to EV supply chains and the second-order exposure to AI power needs, provides a robust structural context for the company's growth trajectory.

3. Business Overview

Company Profile: ON Semiconductor Corporation operates as a global provider of sophisticated power and sensing solutions. The company's operations are structured into three main divisions: the Power Solutions Group (PSG), the Advanced Solutions Group, and the Intelligent Sensing Group.

Business Model & Industry: The company designs and manufactures a broad array of semiconductor products, including analog components, discrete devices, modules, and integrated circuits. These products perform critical functions such as power switching, energy conversion, signal conditioning, and voltage regulation. The business model relies on a mix of direct sales and distributor channels, with sales to distributors accounting for approximately 54% of revenue in 2025.

Supporting Evidence (as of 2026-06-13):

• Revenue Growth: In the first quarter of 2026, revenue increased more than 2.5 times sequentially, driven by broader adoption across high-volume automotive, industrial, and AI applications.
• GaN Expansion: The overall GaN solutions design funnel, including vertical GaN, exceeds $1.5 billion. Ten products are already sampling, with another 20 sampling in 2026.
• SiC Market Share: At the 2026 Beijing Auto Show in April, ON's silicon carbide (SiC) share of new EV models deployed was approximately 55%.
• Customer Concentration: One distributor customer accounted for approximately 12% of total revenue in the quarter ended April 3, 2026.
• Strategic Acquisitions: The company completed the acquisition of the SiC JFET technology business from Qorvo for $118.8 million in January 2025 and acquired rights to Vcore power technologies from Aura Semiconductor for up to $144 million in October 2025.
• Long-Term Visibility: As of April 3, 2026, remaining performance obligations under multi-year Long-term Supply Agreements (LTSAs) were approximately $6.5 billion.

4. Archetype and Conviction

Archetype: Quality Compounder Rationale: ON fits the "Quality Compounder" archetype due to its consistent execution in high-growth secular themes, strong balance sheet management, and ability to generate cash flow for share repurchases.

• Margin Inflector: Management expects sequential gross margin expansion throughout 2026, driven by the mix shift toward higher-value GaN and SiC products.
• Capital Allocation: During 2025, the company repurchased approximately 27.9 million shares for an aggregate price of $1,375.0 million, demonstrating a commitment to shareholder value.
• Valuation Context: The financial spine indicates a forward consensus EPS of $3.09 for FY1 and $4.25 for FY2, suggesting a trajectory of earnings growth that supports the current valuation multiple.

Conviction Stack:

• Thesis Strength: High. The direct exposure to EV electrification and AI power infrastructure provides a durable growth engine.
• Evidence Quality: Strong. Multiple primary sources (earnings transcripts, SEC filings) confirm design wins, market share gains, and revenue growth.
• Structural Quality: The setup is confirmed with a wide stop ($53.50) relative to the entry, offering a favorable risk/reward profile despite the current extension.
• Setup Readiness: The coil is confirmed active, meaning the structural breakout has occurred. The high current ATR (6.7%) suggests volatility but does not negate the confirmed status.
• Rerating Potential: Moderate to High. The combination of margin expansion expectations and the strategic positioning in AI and EV markets supports potential multiple expansion.

5. Invalidation, Strengthening, and Gaps

Invalidation Triggers:

• Fundamental: A significant deterioration in the EV supply chain demand or a failure to maintain the 55% SiC market share in new models would weaken the primary thesis.
• Operational: A breach of the $6.5 billion in remaining performance obligations or a failure to execute the expected gross margin expansion would be negative signals.

Strengthening Factors:

• Design Wins: Confirmation of additional Treo design wins in software-defined vehicles or humanoid robotics.
• GaN Adoption: Acceleration in the sampling and commercialization of the 20+ GaN products expected in 2026.
• Margin Expansion: Confirmation of sequential gross margin expansion in subsequent quarters.

Evidence Gaps:

• Specific AI Revenue Breakdown: While AI data center revenue is mentioned as a growth driver, the specific dollar contribution or growth rate of the AI segment relative to the total is not explicitly quantified in the provided evidence, only described as "exponential" in energy needs.
• Humanoid Robotics Revenue: The exposure to humanoid robotics is noted as a beneficiary, but the revenue impact is currently described as "low confidence" and not quantified in the financials.

PRIVATE ANALYST CALL

Judgment: Buy Confidence: high Key risks: 1) High current ATR (6.7%) indicating elevated volatility and potential for sharp pullbacks; 2) Concentration risk with one distributor accounting for 12% of revenue; 3) Execution risk on the 20+ new GaN product sampling targets; 4) Potential macro slowdown in EV demand despite current growth. Expected path: Management expects continued sequential revenue growth and margin expansion as new GaN and SiC products ramp. The structural setup suggests the price will continue to test higher levels as the market prices in the $4.25 FY2 EPS consensus. Expected horizon: 12 to 18 months for the thesis to fully play out through the 2026-2027 earnings cycle.
