Quick market snapshot

  • Several market reports put the global catalytic-converter / catalytic-converter-related market in the tens of billions USD range (examples: ~USD 67.5B in 2024) with mid-single-digit to high-single-digit CAGR forecasts into the 2030s.

Major companies (who makes catalytic converters / exhaust-aftertreatment components) — company values (public figures / citations)

Many large chemical and automotive suppliers don’t break out “catalytic converters” as a single line item. I list the company + a relevant public revenue / sales figure and short note on their role in catalytic converters / aftertreatment.

  1. Johnson Matthey (Catalyst business — sold) — Johnson Matthey agreed to sell its Catalyst Technologies business to Honeywell for £1.8bn (≈$2.4bn) in May 2025; the Catalyst Technologies unit generated about £728 million revenue in the year to March 31 (the unit was the saleable catalytic/catalyst business). Johnson Matthey will retain/renew focus on Clean Air/platinum group metal processing post-sale.

  2. Umicore — Group revenue €3.5 billion (2024) (Umicore is a major supplier of autocatalyst materials and recycling of precious metals used in converters). 

  3. BASF — Group sales €65.26 billion (2024); BASF supplies catalyst materials and components to automotive and exhaust systems businesses (chemical & materials supplier to converter makers / OEMs).

  4. DENSO Corporation — Group revenue ¥7,144.7 billion (FY 2024); DENSO is a major Tier-1 supplier of engine / exhaust aftertreatment systems and catalyst substrates/assemblies. 

  5. FORVIA (Faurecia — Clean Mobility / formerly Faurecia) — Group sales €27.0 billion (2024); Forvia’s Clean Mobility division (Faurecia) supplies exhaust systems and catalytic converter systems for OEMs.

  6. Tenneco — Automotive supplier with large exhaust & aftertreatment portfolio; public/industry sources place 2023–2024 revenues in the ~$18–19B range (Tenneco is an important global exhaust system & catalytic converter supplier). 

  7. Eberspächer — Exhaust-system specialist; consolidated revenue ~€5.3 billion (2024) (significant provider of exhaust systems and components including monoliths/aftertreatment).

  8. NGK Insulators — Group net sales ~¥619.5 billion (FY 2024); NGK manufactures ceramic monoliths and other components used in catalytic converters and sensors for exhaust purification.

Other notable participants (materials / substrates / components / recyclers): Honeywell (now acquiring Johnson Matthey’s catalyst unit), Corning/NGK/Emitec-affiliates, specialty precious-metal recyclers (various regional players), and regional Tier-1s.

Recent developments (2023–2025)

  • M&A and portfolio reshaping: Johnson Matthey’s Catalyst Technologies unit was agreed sold to Honeywell in May 2025 for ~£1.8bn — a major industry transaction that consolidates catalyst technology capabilities.

  • Market reports (2024–2025) show robust demand for aftertreatment due to emissions regulations worldwide, while precious-metal price swings and EV transition dynamics are shifting supplier strategies.

Drivers

  • Tightening vehicle emissions standards worldwide (Euro, EPA, China) — drives retrofit and OEM demand for higher-efficiency converters.

  • Large installed base of ICE and hybrid vehicles — replacement/aftermarket demand remains sizeable even as EVs grow.

  • Precious-metal recycling & circular economy — high value of PGM (Pt, Pd, Rh) supports recycling and catalyst recovery industries.

Restraints

  • Shift to electrification (EV BEV adoption) reduces long-term demand for catalytic converters in pure BEVs; this leads to uncertainty for OEMs and Tier-1s.

  • Volatility in precious-metal (PGM) prices raises manufacturing cost and margin pressure; supply-chain constraints for substrates and monoliths in some regions.

Regional segmentation analysis

  • Asia-Pacific — largest & fastest-growing in volume (China, Japan, Korea, India): high vehicle production and large aftermarket.

  • North America — strong replacement market and regulatory drivers (US federal/state rules, retrofit programs).

  • Europe — strict emissions standards and well-developed OEM supplier base; transition planning toward hybrid + PHEV tech influences demand.

  • Latin America / MEA — opportunistic replacement/aftermarket growth but lower per-vehicle technology intensity. (See market reports for regional % splits).

Emerging trends

  • Hybridization-first strategy by many OEMs — keeps demand for catalytic converters longer than some BEV-only forecasts.

  • Advanced substrate & washcoat chemistries to reduce PGM loading (cost mitigation) while meeting stricter emission limits.

  • Greater focus on PGM recycling and closed-loop supply chains (recyclers and refiners such as Umicore play a growing role).

  • Consolidation / vertical integration (large acquisitions like Honeywell–JM catalyst deal).

Top use cases

  1. New-vehicle OEM fitment — passenger cars, light & heavy commercial vehicles.

  2. Aftermarket / replacement catalytic converters (aged or failed units).

  3. Retrofit solutions to meet local/regional emissions regulations.

  4. Specialized industrial / non-road applications (generators, off-road machinery).

Major challenges

  • Managing the decline risk from full BEV adoption while servicing near-term ICE/hybrid demand.

  • Cost management given PGM price volatility and raw-material inflation.

  • Lengthy OEM qualification cycles and capital intensity for manufacturing/automation.

Attractive opportunities

  • Aftermarket & retrofit services in regions with large ICE fleets.

  • PGM recovery & recycling services — high margins and growing regulatory/incentive tailwinds.

  • Low-PGM and PGM-free catalyst technologies for cost reduction and future regulatory compliance.

  • Diversification into hybrid/plug-in hybrid aftertreatment solutions (rather than pure EV-only bets).

Key factors of market expansion

  • Continued regulatory pressure on tailpipe emissions and NOx/HC/CO limits.

  • Pace of vehicle turnover and replacement cycles in emerging markets.

  • Technological improvements that lower PGM loading per converter while retaining performance.

  • Investment in recycling infrastructure (catalyst collectors → refiners) to reduce upstream PGM supply risk.

Selected high-impact sources (read these for verification / deeper data)
