ON Semiconductor makes the specialized power and sensing chips that act as the nervous system for electric vehicles, industrial robots, and AI data centers. The company generated $7.08 billion in revenue last year, though it is currently navigating a cyclical downturn in the broader chip market. Despite this cooling, the business is pivoting toward high-margin "intelligent" power solutions, particularly Silicon Carbide chips that help electric cars drive further on a single charge.
The investment thesis on ON Semiconductor is that it owns a vertical advantage in Silicon Carbide (SiC) that rivals cannot easily match, allowing it to capture more profit as vehicles and data centers go electric. While competitors often buy their raw materials from third parties, ON manufactures its own SiC crystals and wafers, controlling the process from start to finish. If it can maintain this manufacturing edge while the industrial market recovers, earnings will likely grow significantly faster than the broader industry.
We believe ON Semiconductor is a high-quality business trading at a discount because investors are focused on a temporary slump in car sales rather than its growing role in AI power. The company has already proven it can win massive long-term contracts with global carmakers, and the recent surge in AI data center demand provides a new, fast-growing growth engine. What would worry us is a prolonged freeze in industrial spending that prevents profit margins from recovering.
On Semiconductor stock soared over the last five years as the company became a key player for electric cars and robots. The price jumped significantly recently because the business started selling specialized power chips that help electric vehicles drive much farther. Demand for this technology keeps growing as factories and data centers automate.
What does it do?
ON Semiconductor is a maturing business that earns money by designing and manufacturing chips that manage electricity and "sense" the physical world. The company focuses on two main categories: power solutions and sensing solutions. When an electric vehicle (EV) accelerates, ON’s power chips manage the high-voltage flow from the battery to the motor. When an industrial robot moves, its sensing chips provide the "eyes" to navigate. Customers pay for the hardware, but the real value is in the proprietary manufacturing processes—like vertical integration for Silicon Carbide—that make these chips more efficient than standard silicon.
Where does revenue come from?
The majority of revenue comes from the Power Solutions Group, which provides high-efficiency power management for cars and factories. This segment accounts for about 50% of the business, followed by the Advanced Solutions Group (35%) which handles signal processing, and the Image Sensor Group (15%) which makes high-resolution sensors. Geographically, ON is a global business, with significant revenue coming from Asia and North America where major EV and industrial manufacturing hubs are located.
Revenue Breakdown
Revenue by Geography
Who are its customers?
ON Semiconductor serves a diverse base of over 50,000 customers, including major car manufacturers and industrial giants like Mercedes-Benz, Hyundai, and various Tier-1 automotive suppliers. In 2024, automotive revenue represented over 50% of total sales, driven by the shift toward electrification and advanced safety features. The company also serves the industrial market, providing chips for solar energy storage and automation. While the total customer count is massive, the top 10 customers often account for a significant portion of the revenue due to the large scale of global car production contracts.
What gives it staying power?
Its vertical integration in Silicon Carbide (SiC) is its strongest defense, as it controls the entire supply chain from raw crystal growth to finished chip. This is a difficult, high-stakes manufacturing process that creates massive switching costs for carmakers who design their vehicle architectures around ON's specific power profiles.
Where is it headed?
The company is aggressively shifting its focus toward AI data centers and sustainable energy to reduce its dependence on the traditional car market. Management is betting that AI servers, which consume massive amounts of power, will require the same high-efficiency chips that ON developed for electric vehicles. If this transition works, it adds a high-growth software-style tailwind to a hardware business.
The business is currently at a cyclical bottom, with revenue expected to hit $6.00 billion in 2025 before starting a recovery. This decline from $8.25 billion in 2023 reflects a broad slowdown in industrial and automotive spending, but the stabilization of quarterly revenue at roughly $1.51 billion suggests the worst is over.
Cash generation remains high despite the earnings slump, with $1.42 billion in free cash flow expected for 2025. This indicates that ON is disciplined with its spending and is effectively managing its inventory levels as it waits for demand to return.
The balance sheet is exceptionally strong with a debt-to-equity ratio of only 0.41x. This low leverage gives the company the flexibility to keep investing in its Silicon Carbide factories and buy back shares even while its customers are pulling back.
ON Semiconductor is a financially resilient company currently weathering a difficult part of the semiconductor cycle. While revenue is down, the business continues to generate more cash than it needs for operations, positioning it to benefit heavily when demand for electric vehicles and AI servers inevitably re-accelerates.
The AI data center business is scaling rapidly, growing from near-negligible levels to a $250 million annual run rate. This new revenue line is offsetting some of the weakness in traditional industrial markets and proves the company's power chips are relevant beyond just cars.
Gross margins have compressed to 37.2%, reflecting the impact of lower factory utilization and heavy investments in new technology. If margins do not begin to climb back toward 40% as revenue recovers, it would suggest that competition in the Silicon Carbide market is becoming more intense than expected.
The power semiconductor market is roughly $50 billion today and is on track to exceed $75 billion by 2028 as the world shifts toward electric vehicles and AI data centers. This is a fundamentally attractive industry because high-voltage power management is a physical requirement of electrification, not a discretionary feature. While the industry is currently in a cyclical downturn, the long-term trend is driven by a structural shift toward energy efficiency that gives specialized players significant pricing power. ON Semiconductor is a top-three leader in this space, positioned specifically to capture the high-value transition from silicon to silicon carbide. Silicon Carbide is the decisive force shaping this market for the next decade.
The market for power semiconductors is rationally structured but requires massive capital investment to stay competitive. Barriers to entry are high because growing high-quality silicon carbide crystals is a difficult chemical process that takes years to master. Pricing power is generally stable because these chips are mission-critical components that represent a small fraction of a vehicle's total cost.
STMicroelectronics and Infineon are the primary threats, as both have deep, decade-long relationships with European and Asian carmakers. Wolfspeed is a specialized threat in the raw material supply, but its recent manufacturing struggles have highlighted the difficulty of the "wafer-to-wafer" manufacturing model. STMicroelectronics is the most dangerous threat due to its similar vertical integration strategy and strong presence in the high-volume Tesla supply chain.
ON is currently holding its ground in the premium automotive sector while gaining significant share in the fast-growing Chinese EV market. The company’s ability to sign multi-billion dollar long-term supply agreements is clear evidence of its competitive standing. The competition is intense, but the market is expanding fast enough to support multiple winners.
The primary source of protection is ON’s internal manufacturing expertise, specifically its vertical integration in Silicon Carbide. By growing its own crystals and processing its own wafers, ON can optimize the chip design for performance and cost in a way that companies buying wafers from others cannot. This vertical integration creates a structural cost advantage and ensures a reliable supply for massive car companies.
The financial data supports a narrow moat: while current TTM ROIC has dipped to 5.4% during a cyclical bottom, it was over 20% during the market peak. This volatility is typical of the semiconductor industry, but the high gross margins on specialized automotive products prove that ON is not selling a commodity. The numbers show a business that has real pricing power in its core markets.
The forward-looking verdict is that this moat is strengthening as ON moves further into specialized "intelligent" power systems. The transition to AI data centers provides a new use case where ON’s efficiency edge is even more valuable than in cars. The vertical integration in SiC is the single most important signal that the moat is durable.

Capital Allocation Track Record
Hassane El-Khoury has fundamentally transformed ON from a "supermarket" of low-margin commodity chips into a focused leader in high-value automotive and industrial power. Since taking over in late 2020, he has aggressively cut costs, exited non-core businesses, and secured massive long-term supply agreements with major global carmakers. The execution has been exceptionally high, as evidenced by the company's ability to maintain profitability even during the current cyclical trough.
While the thesis depends heavily on El-Khoury’s strategic vision, he has built a credible bench of executives who have executed the "Fab-Liter" manufacturing strategy with precision. Governance risk is relatively low, though the company’s heavy concentration in the automotive sector creates a natural cyclical risk that no management team can fully avoid. The board is independent, and incentives are well-aligned with long-term shareholders through significant equity-based compensation and a clear focus on free cash flow per share.
We expect revenue to grow from $6.5B in FY2026 to $10.6B in FY2031 (~10% CAGR), with EPS growing from $3.10 to $10.97 (~29% CAGR). Demand for silicon carbide chips in electric vehicles and renewable energy systems drives steady volume growth as these markets mature. The shift toward internal manufacturing of high-value products allows the company to spread factory costs over more units. EPS grows faster than revenue because profit margins expand significantly as the company recovers from its cyclical low. Operating margin expected to reach ~32% by FY2031.
AI data center power management becomes a multi-billion dollar business. If ON captures the power tree in AI servers, it creates a massive second growth engine that is less cyclical than automotive.
Dominance in Chinese EV exports through established design wins. Being the primary power partner for surging Chinese EV makers provides a high-volume runway as they expand globally.
Margin expansion through the "Fab-Liter" manufacturing strategy. Exiting older factories and focusing on high-efficiency internal production will structurally lift margins as utilization recovers.
Prolonged electric vehicle demand slump delays the Silicon Carbide ramp. A major slowdown in EV adoption would force ON to carry high fixed costs for factories that are not running at full capacity.
Rapid commoditization of Silicon Carbide by low-cost Chinese competitors. If Chinese state-backed rivals flood the market with cheap SiC wafers, ON’s vertical integration edge could be eroded.
Competitive displacement in AI data centers by larger analog players. Giants like Texas Instruments or Infineon could use their massive distribution to bundle power chips, squeezing ON's new growth line.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach based on the company's fiscal year 2027 earnings power. This framework is the most appropriate for ON because the company is currently in a transition year (FY2026) marked by cyclical industrial weakness; the FY2027 earnings represent a more "normalized" view of the business after the current restructuring benefits are fully realized.
Multiplying the FY2027 EPS estimate of $4.30 by a 32x forward multiple results in a fair value of $138. This 32x multiple sits at the top end of the peer range (Texas Instruments 30x, Analog Devices 32x, STMicroelectronics 18x), a premium we believe is justified by ON's superior growth trajectory in the AI data center and Silicon Carbide markets. The input basis uses the consensus analyst estimate for FY2027, which aligns with our view of a mid-cycle recovery in automotive demand.
A 5-year Discounted Cash Flow (DCF) cross-check produces a fair value of $145, which is within 5% of our $138 target and confirms our valuation stance. Using a 10% discount rate and the deterministic engine's projected free cash flow ramp, the DCF accounts for the long-term compounding value of the Silicon Carbide pivot that a single-year multiple might understate. The two methods are in strong agreement, suggesting that $138 is a defensible, non-speculative estimate of intrinsic value.
We're assuming the "FabRight" manufacturing transition delivers a structural expansion in profit margins through 2027. Management is actively reducing fab capacity and exiting low-margin non-core products, which should reduce depreciation by up to $50 million in 2026 and allow the company to maintain higher prices even as volume fluctuates.
We're assuming ON sustains a dominant market share in the high-voltage AI data center power market. AI architectures are shifting toward higher-voltage bus systems where ON's specialized power modules offer a 50% footprint reduction; we expect this high-value niche to grow high-teens percent annually and buffer the company against weakness in general-purpose industrial chips.
We're assuming a successful ramp-up of the Treo platform and next-generation Silicon Carbide (SiC) modules. With a design funnel already exceeding $1 billion, these products are the primary engine for reaching the projected $5.77 EPS by 2028, requiring the company to maintain its vertical integration advantage over peers who outsource their substrate supply.
The biggest risk is a prolonged downturn in the global automotive sector that offsets the gains in Silicon Carbide adoption. This would likely force the forward multiple down from 32x to 22x, knocking roughly $43 off the per-share fair value. Watch for any quarterly decline in the Power Solutions Group (PSG) revenue below $700 million as an early warning signal.
Bear case ($101): Silicon Carbide (SiC) gross margins drop below 35% due to aggressive pricing from Chinese competitors; or Non-AI automotive revenue declines more than 15% year-over-year for two consecutive quarters.
Bull case ($155): AI data center revenue exceeds $350 million for the full fiscal year 2026; or The "FabRight" initiative accelerates, pushing non-GAAP gross margins above 42% by late 2026.

The market is bullish because ON Semiconductor controls a critical vertical supply chain for power chips that electric vehicles and data centers cannot do without. Their focus on Silicon Carbide technology gives them a manufacturing edge in making power systems that are more efficient. By controlling the entire production process, they keep higher profits for every chip sold.
Skeptics think that rapid innovation by competitors like Wolfspeed and Diodes Incorporated will eventually erode the company's current pricing power. These rivals are aggressively pushing new power technologies like Gallium Nitride and lower-resistance switches that threaten to turn ON Semiconductor's specialized parts into common commodities with thinner profit margins.
