    Powering the Recovery: A Deep Dive into onsemi (ON) and the Future of Silicon Carbide

    As of March 6, 2026, the global semiconductor industry is emerging from a protracted "inventory digestion" phase that defined much of 2024 and 2025. At the heart of this recovery is onsemi (Nasdaq: ON), a company that has undergone a radical transformation from a broad-based commodity chipmaker into a specialized powerhouse in "intelligent power and sensing."

    The focus on onsemi today is driven by its strategic pivot toward Silicon Carbide (SiC) and its resilience in a volatile automotive and industrial landscape. Under the leadership of CEO Hassane El-Khoury, the company has executed an aggressive "Fab-Right" strategy, shedding underperforming assets to focus on high-margin, high-growth technologies. This deep dive explores how onsemi is positioning itself to lead the next generation of electric vehicles (EVs), AI-driven data centers, and industrial automation.

    Historical Background

    The story of onsemi begins on August 4, 1999, when it was spun off from Motorola’s Semiconductor Components Group. Initially headquartered in Phoenix, Arizona, the company (then known as ON Semiconductor) inherited a massive portfolio of discrete, logic, and analog devices. The early years were marked by survival, as the company navigated the 2001 tech bust and worked to modernize its manufacturing footprint.

    Over the next two decades, onsemi utilized strategic M&A to climb the value chain. Key milestones include the 2008 acquisition of AMI Semiconductor, the 2011 purchase of SANYO Semiconductor, and the transformative $2.4 billion acquisition of Fairchild Semiconductor in 2016, which catapulted the company into the upper echelons of power management leaders.

    In 2021, the company rebranded as onsemi to reflect a new strategic focus. That same year, it acquired GT Advanced Technologies (GTAT), a move that proved visionary by providing the company with internal control over its Silicon Carbide (SiC) substrate supply chain, a critical component for the burgeoning EV market.

    Business Model

    onsemi operates through three primary segments, each targeting high-value, high-growth "megatrends" in the electronics industry:

    1. Power Solutions Group (PSG): The company’s largest revenue driver, accounting for roughly 47% of sales. It focuses on power management components, including SiC modules, MOSFETs, and IGBTs, which are essential for EV drivetrains and energy infrastructure.
    2. Advanced Solutions Group (ASG): This segment provides mixed-signal, analog, and logic solutions for automotive, industrial, and medical markets. This includes the Treo Platform, a 65nm BCD process used in precision sensing and power control.
    3. Intelligent Sensing Group (ISG): A leader in image sensors, ISG serves the automotive (ADAS and cabin monitoring) and industrial sectors. onsemi holds a dominant market share in automotive image sensors, which are critical for autonomous driving.

    The company’s customer base is heavily weighted toward Automotive (approx. 52%) and Industrial (approx. 28%), with the remainder coming from the AI data center and consumer markets.

    Over the last decade, onsemi has been a volatile but rewarding investment.

    • 10-Year View: From 2016 to early 2026, the stock has grown from roughly $10 to over $60. Much of this growth occurred during the "SiC gold rush" of 2021–2023, where shares hit an all-time high of approximately $108.09 in August 2023.
    • 5-Year View: The stock saw a massive acceleration under the current management team, outperforming many peers in the PHLX Semiconductor Index (SOX) between 2021 and 2023.
    • Recent Performance: The 2024–2025 period was difficult. As EV demand softened and industrial inventories swelled, the stock entered a consolidation phase, trading between $50 and $75. As of March 2026, the stock is showing signs of a fresh breakout, supported by a newly launched $6 billion share repurchase program.

    Financial Performance

    In early 2026, onsemi is emerging from a cyclical trough.

    • Revenue: After peaking at $8.25 billion in 2023 and dipping to approximately $6.0 billion in 2025, revenue is projected to rebound to $9.0 billion by the end of the 2026/2027 cycle.
    • Margins: Management’s "Fab-Right" strategy has been successful in protecting profitability. Non-GAAP gross margins remain robust at 45%+, with a long-term target of 53% as 200mm SiC production scales.
    • Cash Flow & Debt: The company reported a free cash flow of $1.4 billion in 2025 (24% of revenue). This strong liquidity position allowed for the massive $6 billion buyback program announced in late 2025, aimed at reducing share count and boosting EPS.
    • Valuation: Trading at a Forward P/E of approximately 23x, onsemi is viewed as reasonably valued compared to its 5-year historical average, particularly given the expected EPS rebound in late 2026.

    Leadership and Management

    The leadership team is widely credited with onsemi’s structural improvement:

    • Hassane El-Khoury (President & CEO): Since joining in late 2020, El-Khoury has been the architect of the "intelligent power and sensing" pivot. His disciplined approach to capital allocation and "asset-right" manufacturing has revitalized the company's reputation on Wall Street.
    • Thad Trent (EVP & CFO): Also joining in 2021, Trent has overseen the divestiture of low-margin fabs and the implementation of a rigorous financial model focused on free cash flow and margin expansion.
    • Simon Keeton (Group President, PSG): A veteran of the company, Keeton leads the high-growth Power Solutions Group and is currently managing the transition to 200mm SiC wafers, a critical technical hurdle for the company.

    Products, Services, and Innovations

    The crown jewel of onsemi’s current portfolio is the EliteSiC™ brand. Silicon Carbide is superior to traditional silicon for high-voltage applications because it is more efficient, handles higher temperatures, and allows for smaller, lighter power systems.

    • EliteSiC M3e MOSFETs: Launched in late 2024, the M3e generation reduced conduction losses by 30%, making it the industry standard for 800V EV traction inverters.
    • 200mm (8-inch) SiC Transition: In 2026, onsemi successfully ramped its 200mm SiC production in Bucheon, South Korea. Moving from 150mm to 200mm wafers increases the number of chips per wafer by ~80%, providing a massive cost advantage.

    • Energy Infrastructure: The global upgrade of the "smart grid" to handle renewable energy (solar/wind) requires massive amounts of the power semiconductors that onsemi specializes in.
    • Strategic M&A: With a strong cash position, onsemi is rumored to be looking at specialized AI software or Gallium Nitride (GaN) startups to further round out its "Intelligent Power" portfolio.

    Investor Sentiment and Analyst Coverage

    Wall Street remains generally bullish on onsemi, with a "Moderate Buy" consensus. Analysts from Goldman Sachs and Morgan Stanley have highlighted the company’s "structural margin expansion" as a reason for its premium valuation compared to traditional analog chipmakers like Texas Instruments (Nasdaq: TXN).

    Institutional ownership is high at approximately 95%, indicating that "smart money" views onsemi as a core long-term holding for exposure to the electrification of the global economy. Retail sentiment, while more volatile, often tracks the news cycle of major EV makers like Tesla and Rivian.

    Regulatory, Policy, and Geopolitical Factors

    onsemi is a strategic beneficiary of current geopolitical shifts:

    • US CHIPS Act: onsemi has secured significant federal funding to expand its manufacturing sites in East Fishkill, New York, and Mountain Top, Pennsylvania, reducing its reliance on Asian foundries.
    • EU Chips Act: The company’s $2 billion investment in the Czech Republic is bolstered by European subsidies aimed at securing a domestic supply of power electronics for the EU’s automotive industry.
    • Export Controls: Tightening US restrictions on the export of high-efficiency SiC technology to China act as a protective barrier for onsemi’s intellectual property and market share.

    Conclusion

    As of February 9, 2026, ON Semiconductor has successfully shed its past as a commodity chipmaker to become an indispensable pillar of the high-voltage future. By vertically integrating its Silicon Carbide supply chain and pivoting toward the power-hungry needs of AI data centers, management has insulated the company from many of the cyclical pressures that plague the broader semiconductor industry.

    While the "China factor" and the pace of EV adoption remain valid concerns, onsemi’s transition to 200mm manufacturing and its dominance in automotive sensing provide a robust moat. For investors, onsemi represents a high-conviction play on the fundamental thesis that the world of tomorrow will require more efficient power management than the world of today. The key to its future success will lie in its ability to maintain its technological lead in SiC while executing its "Fab-Right" efficiency gains.
