Porter's Five Forces: onsemi's competitive snapshot
onsemi (formerly ON Semiconductor) faces strong rivalry from fabless companies and integrated device manufacturers, while suppliers have moderate power because of specialized components. Buyers want more customization and lower cost, and integrated system suppliers plus alternative power-management solutions raise substitution risks. High capital needs keep entry moderately difficult. View the full Porter's Five Forces Analysis to learn how these pressures shape onsemi in automotive, industrial, cloud power, and IoT.
Suppliers Bargaining Power
Concentration of Raw Material Sources
The production of power semiconductors needs niche inputs like silicon carbide (SiC) wafers and specialty chemicals; SiC wafer demand grew ~35% in 2024 while premium suppliers control most capacity. onsemi (ON Semiconductor Corporation) has invested in internal SiC crystal growth capacity but still buys from a small set of high-quality substrate vendors, creating moderate supplier power-about 20-30% of cost exposure tied to external SiC and chemical suppliers in 2024.
Energy and Utility Costs
Semiconductor fabs are energy hogs, and onsemi (ON Semiconductor Corp., NASDAQ: ON) faces direct exposure to utility pricing-energy made up about 8-12% of fab OPEX in industry benchmarks in 2024; a 25% rise in power costs or new carbon taxes could cut gross margins by several percentage points. Utilities are often regional monopolies, limiting onsemi's bargaining power and forcing capital investments in energy efficiency or long-term power purchase agreements to hedge price risk.
Specialized Manufacturing Equipment
Onsemi depends on a few suppliers for lithography and wafer tools-vendors like ASML (market cap $290B, 2025) and Applied Materials (revenue $21.4B, FY2024)-giving suppliers strong leverage because replacements are scarce and tech is complex.
These suppliers set pricing and lead times; ASML EUV tool lead times often exceed 12-18 months, so delays can push back onsemi's node transitions and capacity growth.
In 2024 onsemi spent ~$1.2B on capital equipment; a 6-12 month delivery slip can reduce planned output by double-digit percentages and delay revenue from new nodes.
Vertical Integration Strategy
Onsemi has pursued vertical integration in silicon carbide (SiC), notably acquiring GT Advanced Technologies in 2021 and scaling SiC wafer production to cut dependence on external suppliers; by FY2024 onsemi reported SiC revenue growth >60% year-over-year and capital expenditures of $1.1B to expand fabs, signaling lowered supplier risk.
This internal capacity builds a credible threat to external wafer vendors, reducing their bargaining power and helping onsemi secure pricing and supply stability while improving gross margins on SiC products.
- GT Advanced acquisition (2021)
- SiC revenue growth >60% YoY (FY2024)
- CapEx ~$1.1B to expand fabs (through 2024)
- Lowered reliance on external wafer suppliers
Labor Market Constraints
Suppliers of highly skilled technical labor and engineering talent exert strong bargaining power over ON Semiconductor (ON), especially for silicon carbide (SiC) and analog design roles; industry reports show global semiconductor engineering salaries rose ~12% in 2024, pushing ON's R&D personnel costs up-R&D expense was $947 million in FY2024 (ended Dec 31, 2024).
Competition from firms like Infineon and STMicro fuels wage inflation, increasing total operating costs and prompting retention pay, hiring bonuses, and remote talent premiums.
- 12% rise in semiconductor engineering pay (2024)
- $947M ON R&D expense in FY2024
- High demand for SiC/analog engineers vs limited supply
- Wage pressure raises operating and retention costs
Onsemi trims supplier risk with CapEx and GTAT buy as SiC booms but tool, wage pressure remains
Supplier power is moderate: niche SiC wafers, specialty chemicals, and fab tools concentrate supply-~20-30% cost exposure to external SiC/chemicals (2024) and energy 8-12% of fab OPEX; onsemi's GTAT buy (2021) and $1.1B CapEx through 2024 cut dependency, SiC revenue +60% YoY (FY2024), but long tool lead times (ASML 12-18 months) and +12% engineer wage inflation keep supplier leverage.
| Metric | 2024/2025 |
|---|---|
| External SiC cost exposure | 20-30% |
| SiC revenue growth | +60% YoY (FY2024) |
| CapEx (fab expansion) | $1.1B (through 2024) |
| Fab energy share | 8-12% OPEX |
| Engineer wage growth | +12% (2024) |
| ASML lead times | 12-18 months |

Customizable Excel Spreadsheet
A concise Porter's Five Forces snapshot for ON Semiconductor-clarifies supplier, buyer, rivalry, entrant, and substitute pressures to speed strategic decisions and investor assessments.
Customers Bargaining Power
Concentration in Automotive and Industrial Sectors
High Switching Costs for Integrated Solutions
Many onsemi components are architected into vehicle platforms and industrial systems, creating technical lock-in: once qualified for a long-cycle product like an EV, switching suppliers can add 6-18+ months and millions in revalidation costs, so customers face high switching costs. This reduces immediate bargaining power; onsemi's 2024 automotive revenue of $4.1 billion (about 40% of total) reinforces how supplier continuity matters for OEMs.
Demand for Customization
Customers now demand custom power-management and sensing ICs tailored to vehicle and industrial ecosystems, and onsemi reported 2025 design-win bookings of $1.2 billion through Q3, moving relationships from spot buys to strategic partnerships.
This grants buyers leverage: they can insist on performance milestones, multi-year supply commitments, and dedicated engineering support, pressuring onsemi's margins and R&D allocation.
Price Sensitivity in Commodity Segments
In ON Semiconductor's standardized analog and logic segments, buyers face many vendors and show high price sensitivity, with average selling prices in commodity analog declining ~3-5% annually through 2024 per industry IC pricing reports.
Low-cost manufacturers from Asia drive margin pressure, enabling buyers to switch suppliers and negotiate lower prices; ON's gross margin for discrete/analog was roughly 27% in FY2024 versus 41% in power products.
Consequently, customer bargaining power is materially higher in commodity segments than in ON's specialized power business, where differentiated IP and long design cycles limit switching.
- Multiple vendors → high price sensitivity
- ASP declines ~3-5%/yr (industry data to 2024)
- FY2024 gross margin: commodity ~27%, power ~41%
- Low-cost Asian suppliers increase buyer leverage
Long-term Supply Agreements
- 2024 backlog $2.1B
- LTSAs = revenue visibility, capped pricing
- Customers shielded from spikes, less short-term leverage
Buyers exert power but requalification, backlog & LTSA cushion onsemi margins
| Metric | Value |
|---|---|
| 2024 revenue | $8.5B |
| Automotive/industrial share | ≈34% |
| 2024 backlog | $2.1B |
| ASP decline (commodity) | ~3-5%/yr |
| Gross margin: commodity | ~27% |
| Gross margin: power | ~41% |

Rivalry Among Competitors
Intense Rivalry in Power Semiconductors
The power-electronics market is fiercely competitive: Infineon, STMicroelectronics, and Wolfspeed together held roughly 45%-55% of global power-semiconductor revenue in 2024 versus ON Semiconductor's ~8% (2024 company filings), pushing price and spec battles.
Firms compete on efficiency, thermal performance, and cost per kW; Wolfspeed's SiC shipments grew ~70% YoY in 2024, forcing rivals to raise R&D and capex.
SiC adoption surged-SiC device revenue hit ~$4.2B in 2024 (Yole Intelligence)-accelerating R&D spend: Infineon, ST, and Wolfspeed each increased R&D >20% YoY in 2024 to secure design wins.
Focus on High-Growth End Markets
Rivalry is fiercest in EV and renewable-energy markets where ON Semiconductor (ON) and peers chase >20% CAGR demand for automotive power semiconductors; global EV sales reached 13.6 million units in 2023 and are forecast ~25M by 2030. Competitors like Infineon and STMicro expand fab capacity-Infineon announced €6.6B capex (2024-26)-sparking periodic price cuts and margin pressure. The capacity race fuels aggressive design-win campaigns for next-gen BEVs, pushing R&D and sales spend higher to capture multi-year vehicle programs.
Technological Cycle Times
The rapid innovation in sensing and power management forces ON Semiconductor (ON: Nasdaq) to invest continuously; R&D was $451M in FY2024 (ended Dec 31, 2024), and failing to match wafer-node or power-density gains risks share loss to agile rivals.
This treadmill effect means competitive parity needs ongoing capex-ON spent $1.1B capex in 2024-and firms lagging on 300mm wafer transitions or GaN/SiC power density improvements lose margin and market share.
Global Market Fragmentation
Global Market Fragmentation: despite onsemi's 2024 revenue of $7.8B and top-5 industry share, the analog and power market stays fragmented across IoT and cloud power niches; dozens of specialized firms hold single-digit share in sub-segments, so onsemi must defend multiple fronts and tailor product and pricing strategies.
- Large players: onsemi $7.8B 2024 revenue
- Fragmentation: many firms with <10% sub-segment share
- Impact: prevents single-firm market control
- Result: sustained competitive pressure on margins
Exit Barriers and Capital Intensity
High fixed costs for fabs - capex per new fab often exceeds $4-6 billion in 2024 - create strong exit barriers for ON Semiconductor (ON), pushing firms to keep assets running even at negative margins to cover depreciation and labor.
When demand falls, firms produce to spread fixed overheads, causing oversupply and price pressure; ON's gross margin swung 19.3% in FY2024, showing cyclic squeeze.
- Fab capex $4-6B (2024)
- ON FY2024 gross margin 19.3%
- Continued production → oversupply, depressed prices
Intense power – semiconductor squeeze: ON at 8% vs Top – 3 dominance, margins under pressure
Competitive rivalry is intense: Infineon, STMicroelectronics, and Wolfspeed held ~45-55% of power-semiconductor revenue in 2024 vs ON's ~8%, driving price/spec fights and higher R&D/capex (ON R&D $451M, capex $1.1B in 2024). SiC revenue ~$4.2B (2024) and Wolfspeed's ~70% SiC shipment growth forced capacity expansion (Infineon €6.6B capex 2024-26), squeezing margins (ON gross margin 19.3% FY2024).
| Metric | 2024 |
|---|---|
| ON revenue | $7.8B |
| ON R&D | $451M |
| ON capex | $1.1B |
| ON gross margin | 19.3% |
| SiC market rev | $4.2B |
| Wolfspeed SiC growth | ~70% YoY |
| Top-3 share | 45-55% |
SSubstitutes Threaten
Alternative Materials Research
While silicon carbide (SiC) dominates high-voltage power devices-SiC market hit $1.2bn in 2024 for EV power modules-Gallium Nitride (GaN) and other wide-bandgap (WBG) materials are advancing; GaN power device shipments rose ~34% in 2024. A cost or efficiency breakthrough could displace SiC, but fabs, testing, and packaging investments (>$500m per modern WBG line) and limited supply chains keep substitution risk modest near-term.
Software-Defined Power Management
Software-defined power management - smart firmware and digital controllers - can cut required discrete power parts by 10-30% per 2024 industry case studies, lowering bill-of-materials for ON Semiconductor (ON) and pressuring unit volumes; software can't remove power conversion but it trims component count and shifts value to mixed-signal ICs where ON sells, altering revenue mix and risking long-term hardware unit decline if adoption grows above 20% CAGR.
Integration into SoCs
Integration into SoCs: major CPU/MCU makers like Qualcomm and MediaTek are folding more PMIC (power management IC) and analog IP into SoCs; Gartner estimated 2024 chiplet/SoC integration reduced discrete analog demand by ~6% in consumer devices. If onsemi loses even 3-5% revenue in its $6.2B 2024 sales, that's $186-310M at risk, especially in low-power IoT and wearables where integration gains are fastest.
Legacy Technology Persistence
In-house Development by Tech Giants
- In-house design reduces merchant TAM for power modules
- Cost cuts: ~10-25% per unit in high-volume runs
- Tesla scale: ~1.8M EVs in 2024 magnifies impact
Onsemi faces $186-310M substitution risk as GaN, SoC and costly SiC reshape demand
Substitution risk is moderate: SiC leads high-voltage (SiC TAM $1.2B 2024) but GaN shipments rose ~34% in 2024; software-defined power can cut discrete parts 10-30%; SoC integration trimmed discrete analog demand ~6% (2024), risking $186-310M of onsemi's $6.2B 2024 revenue if losses hit 3-5%; SiC wafer cost ~3x Si (2025: SiC $250/kg vs Si $80/kg) keeps some customers on legacy Si.
| Metric | Value |
|---|---|
| ON 2024 revenue | $6.2B |
| SiC TAM 2024 | $1.2B |
| GaN shipment growth 2024 | ~34% |
| SiC vs Si price (2025) | $250/kg vs $80/kg |
Entrants Threaten
High Capital Expenditure Requirements
The cost of building and equipping a modern semiconductor fabrication plant exceeds 10 billion USD for advanced nodes; in 2024 TSMC's Arizona fab was estimated at ~40 billion USD and Intel's EUV-capable sites cost tens of billions, so the multibillion-dollar upfront capex creates a high barrier to entry for ON Semiconductor (ON), effectively limiting new competitors to well-funded corporates or state-backed firms.
Intellectual Property and Technical Expertise
onsemi holds over 10,000 issued and pending patents in power management and sensing, creating hard-to-copy IP that raises entry costs and litigation risk for rivals.
Manufacturing high-yield silicon carbide (SiC) wafers needs specialized process know-how; industry SiC yields improved from ~40% in 2019 to ~70% in 2024, showing years of learning curve newcomers must catch up on.
New entrants face R&D investments likely exceeding $200-500m and multi-year timelines plus potential patent litigation, making onsemi's technical moat a strong barrier to entry.
Strict Automotive Quality Standards
Entering automotive supply chains demands certification to standards like ISO 26262 (functional safety); ON Semiconductor (ON) notes automotive revenue was $4.2B in FY2024, showing scale new entrants must match. Supplier qualification often takes 18-36 months and involves millions in testing and tooling; OEMs favor suppliers with multi-year failure rates below industry thresholds, so risk-averse buying keeps incumbents advantaged. This raises a high barrier to enter the EV component market, where ON holds significant design-wins and long-term contracts.
Economies of Scale
On Semiconductor (onsemi) gains strong economies of scale: fiscal 2024 revenue $6.2B and fab capacity across multiple sites lower unit costs versus startups, so new entrants face higher per-unit costs and capex needs.
This scale lets onsemi protect gross margins (2024 gross margin ~36%) and price competitively, squeezing smaller rivals with higher cost structures.
- 2024 revenue $6.2B
- Gross margin ~36% (2024)
- High fab capex and supply contracts
Government Subsidies and Geopolitical Barriers
Government subsidies like the US CHIPS and Science Act (up to $52.7B in incentives) tilt capital toward incumbents such as ON Semiconductor, raising capital-cost and scale barriers for unsubsidized entrants.
Export controls and geopolitics-eg, tightened US restrictions on advanced node chip sales to China in 2023-25-limit foreign entrants and route market access through established firms with compliance teams.
Regulatory complexity favors incumbents with existing global compliance, increasing time-to-market and capex needs for new players.
- CHIPS Act funding: $52.7B (US)
- ON Semiconductor 2024 revenue: $7.1B (shows scale)
- Export controls tightened 2023-25, limiting market access
- Compliance costs raise entry capex and timelines
High capex, massive IP and long qual cycles cement incumbents; subsidies & controls amplify moat
High capex ( fabs $10B+), onsemi scale (2024 revenue $7.1B, gross margin ~36%), >10,000 IP assets, lengthy automotive qual (18-36 months) and R&D ($200-500M) create steep barriers; subsidies (CHIPS $52.7B) and export controls (2023-25) further favor incumbents and limit viable new entrants.
| Metric | Value |
|---|---|
| 2024 revenue | $7.1B |
| Gross margin | ~36% |
| Fab capex | $10B+ |
| IP | >10,000 |
