What CDTI does

CDTi Advanced Materials (NASDAQ: CDTI) is a public cleantech emissions-control and catalyst engineering company that designs, develops, and manufactures catalyst and coating solutions for industrial, transportation, power generation, mining, and emerging decarbonization applications. Founded by UC Santa Barbara researchers, CDTi applies proprietary catalyst formulation, washcoat chemistry, and substrate-coating know-how across monolith (ceramic/metallic honeycomb), silicon-carbide diesel particulate filters (DPF), and sorbent-coated monoliths for direct air capture (DAC). The portfolio includes branded products (CatTrap, PuriFilter, CombiFilter, AZ Purifier, PuriMuffler, PatFluid/HD/CV, Platinum Plus), a two-stage methane abatement system combining a sulfur guard with a methane oxidation catalyst, ammonia slip catalysts (ASC), and PGM-free electrocatalysts for hydrogen production. The company is supported by 25 patents, ISO 9001:2015 and ISO 14001:2015 certifications, and over 14 million catalysts coated historically.

CDTi operates a sales-led, B2B enterprise go-to-market through direct engagement, collaborative engineering, and pilot-to-production coating programs with global OEMs, Tier 1 automotive suppliers, energy companies, mining operators, and shipping fleets. Revenue is generated from one-time product sales (catalysts, DPFs, fuel-borne catalyst additives) plus professional engineering and coating services tied to customer-sponsored development work in carbon capture, methane abatement, and hydrogen production. The company serves offices in Oxnard, California (headquarters and manufacturing), West Sussex (UK), and Malmö (Sweden), with named reference customers spanning automotive (Honda, GM, Renault), oil & gas and energy (Clairity Technology for Project Juniper, unnamed global energy organizations), maritime (unnamed leading global shipping company for a three-vessel methane abatement pilot), and stationary power (Doosan engines deployed at a California hospital for seven-plus years).

Revenue model

1. Catalyst and Coating Products: CDTi generates revenue primarily from the sale of catalyst products and coating services. This includes emission control catalysts, diesel particulate filters, oxidation catalysts, methane oxidation catalysts, and custom catalyst elements for industrial and power generation applications. Revenue grew from $9.0M in 2024 to $9.9M in 2025, driven by increased demand for catalyst and coating technology for emissions control systems.
2. Engineering and Coating Services: CDTi provides engineering, testing, and development support services alongside production-scale coating programs. Engagements begin with collaborative development and evolve through pilot and production-scale commercialization. Customer-sponsored catalyst and coating technology development work represents a growing revenue stream, particularly in carbon capture and methane abatement.
3. Fuel Borne Catalyst Products: Revenue from fuel additive and fuel-borne catalyst products including PatFluid, PatFluid HD, PatFluid CV (Europe), and Platinum Plus. These products improve diesel engine performance and DPF regeneration while reducing maintenance costs. Revenue from FBC products has experienced short-term volatility with new product line introductions.

Scale indicators7 records

Broad incumbents

• Johnson Matthey: Johnson Matthey is a global leader in automotive catalysts and emissions control technologies, with established OEM relationships and a multi-billion-dollar catalysts division. CDTi competes as a smaller, specialized tier-2 supplier in similar end markets (automotive emissions, mining, industrial) with a differentiated focus on PGM-free formulations and emerging DAC/methane abatement coatings.
• BASF: BASF operates a large Catalysts division covering automotive emissions, chemical process catalysts, and battery materials, with global manufacturing scale and deep OEM relationships. CDTi competes in overlapping emissions and emerging hydrogen/carbon capture markets but at a fraction of the scale, positioning itself as a niche specialty coatings provider to OEMs and emerging clean energy customers.
• Umicore: Umicore is a leading European specialty materials and catalyst company with a strong automotive catalyst business and growing presence in battery materials and recycling. Like CDTi, Umicore serves emissions control applications for OEMs but with substantially larger resources and broader product breadth across the clean energy value chain.
• Clariant: Clariant's Catalysts business produces specialty catalysts for industrial and emissions applications, including syngas, hydrogen, and emissions control. Comparable to CDTi in targeting specialty catalyst niches with high technical content, though Clariant operates at significantly greater scale and broader end-market exposure.
• Tenneco (DRiV): Tenneco's DRiV business (now operating as an independent company) is one of the largest global manufacturers of emissions control and ride performance products for automotive and commercial vehicle markets. Comparable to CDTi in producing diesel particulate filters and emissions catalyst systems, but at vastly greater scale and with established OEM contracts.

Direct peers

• Cataler Corporation: Cataler is a Japanese manufacturer of automotive catalytic converters and emissions catalysts supplying major Japanese OEMs including Toyota. Most directly comparable to CDTi in product scope (emissions catalyst coating and substrate systems) and approach (specialized tier-2 supplier), though at substantially larger scale with different geographic focus.

Emerging players

• Haldor Topsoe: Haldor Topsoe develops catalysts and process technology for hydrogen production, ammonia, methanol, and refining, with growing focus on electrolysis and Power-to-X. Comparable to CDTi in pursuing hydrogen catalyst opportunities and emerging clean energy applications, with deeper specialization in industrial-scale hydrogen and complementary R&D resources.
• Advent Technologies Holdings: Advent Technologies is a small-cap public company developing high-temperature proton exchange membrane (HT-PEM) fuel cell technology and components for hydrogen applications. Comparable to CDTi in being a small public hydrogen/catalyst technology company with portfolio overlap in reversible fuel cells, hydrogen electrolysis catalysts, and energy storage IP.

Others

• Corning Incorporated: Corning manufactures ceramic substrates and particulate filters for catalytic converters and emissions systems, serving as a key supplier to catalyst coaters and OEMs globally. While not a direct competitor, Corning is a critical substrate partner for CDTi and the broader emissions catalyst ecosystem, with overlap in mining and heavy-duty diesel filter markets.
• NGK Insulators: NGK Insulators is a leading global manufacturer of ceramic honeycomb substrates used in automotive catalytic converters and diesel particulate filters. As a substrate supplier upstream of catalyst coaters like CDTi, NGK is an essential ecosystem partner rather than direct competitor, with overlap in supporting global OEM emissions control supply chains.
