Cormetech Acquisition Gives Johnson Matthey a Data Center Power Bet

Cormetech acquisition gives Johnson Matthey a more direct stake in a fast-growing corner of the U.S. power market, where data center expansion is lifting demand for cleaner stationary generation. The British specialty chemicals group agreed to buy the U.S. emissions-control company from investment firm SK Capital for an enterprise value of $360 million in cash, with an additional earn-out of up to $100 million tied to earnings targets in 2028 and 2029.

The transaction matters because it is not just another industrial bolt-on. Johnson Matthey said Cormetech brings a large installed base in stationary selective catalytic reduction systems, a long customer list, and a sizeable orderbook linked increasingly to new power projects serving digital infrastructure and industrial demand. Reuters, citing the company’s results and deal briefing on May 28, said the acquisition reflects a broader bet that electricity demand tied to artificial intelligence and data centers will drive more demand for cleaner backup and onsite generation.

Cormetech Acquisition Gives Johnson Matthey a New Growth Lane

Johnson Matthey has spent the past two years reshaping itself around businesses with clearer returns, stronger market positions, and a more defensible role in energy transition and industrial decarbonization. The company is also in the middle of a bigger portfolio reset after agreeing to sell its Catalyst Technologies arm to Honeywell for 1.8 billion pounds, a move designed to simplify the group and release capital.

Against that backdrop, Cormetech stands out because it is closely tied to a real and immediate operating need rather than a distant technology promise. Power demand from hyperscale data centers, hospitals, utilities, and industrial sites still requires gas turbines, reciprocating engines, and other thermal generation assets, and those systems must comply with tightening emissions rules.

Why the Cormetech Acquisition Fits

Johnson Matthey said Cormetech is expected to generate about $180 million of sales and roughly $35 million of EBITDA in 2026, up from around $129 million of sales and $16 million of EBITDA in 2025. On that basis, the upfront deal value represents about 10.3 times expected 2026 EBITDA before synergies, suggesting Johnson Matthey is paying for growth visibility rather than simply buying distressed capacity.

The company also said Cormetech has more than 400 customers, around 90% of whom have relationships lasting more than a decade. That matters in industrial markets where replacement cycles are long, qualification standards are strict, and customers are reluctant to switch suppliers on critical compliance equipment once a system is running reliably.

Cormetech’s footprint also comes with operating scale. Johnson Matthey said the business employs about 350 people, operates from two U.S. sites, and has supplied catalyst systems covering more than 300 gigawatts of power generation capacity globally. That installed base gives the buyer recurring exposure to maintenance, replacement, and upgrade demand rather than only one-off equipment sales.

A Data Center Demand Signal, Not a Generic Bolt-On

The more striking figure in the transaction materials is the forward demand picture. Johnson Matthey said Cormetech enters the deal with an orderbook of about $300 million for 2026 and 2027 and a pipeline of roughly $1 billion, mainly tied to U.S. data center projects. That does not mean all of the pipeline converts, but it does show where management believes the most attractive new demand is forming.

That framing is important because data center growth is often discussed only through chips, servers, or cooling. The Cormetech purchase highlights a different layer of the build-out: when power grids are constrained or reliability requirements are high, more generation equipment is installed at or near facilities, and that creates a separate market for emissions control and compliance hardware.

For Johnson Matthey, this is a way to capture spending around AI infrastructure without trying to compete in semiconductors or software. Instead, it positions the company in the industrial systems that support reliable power supply when electricity demand rises faster than grid upgrades can keep pace.

Data Center Power Demand Is Redrawing Emissions Control Markets

The industrial logic of the deal goes beyond one company’s earnings mix. Across the United States, developers, utilities, and large energy users are trying to balance faster data center deployment with local air-quality requirements, permitting limits, and pressure to keep power available during outages and peak demand periods.

That tension creates a market for companies that can help gas-fired and diesel-adjacent systems meet nitrogen oxides and other emissions standards. Cormetech’s niche is not glamorous, but it sits close to the regulatory and operational bottlenecks that increasingly shape whether new power capacity can actually be approved and used.

Cormetech Acquisition and Tougher U.S. Rules

Johnson Matthey said the acquisition expands its Clean Air Solutions business into the U.S. stationary emissions-control market, where Cormetech supplies selective catalytic reduction and oxidation catalyst systems. Those technologies are used to reduce pollutants from power-generation assets, including turbines and engines deployed for standby or distributed generation.

The company cited a roughly $1.1 billion global addressable market in 2025 for stationary SCR and oxidation catalysts, based on an Advancy market study, and said that market could grow at about an 11% compound annual rate through 2030. That forecast is the company’s presentation of the opportunity, but the underlying logic is clear enough: cleaner compliance equipment becomes more valuable as more combustion-based generation is added into constrained power systems.

Reuters added another practical angle on May 28 by noting that tighter U.S. regulations are expected to support demand for the business. That helps explain why Johnson Matthey is willing to add leverage for a U.S.-focused asset even while it is working through a broader restructuring and preparing a large capital return after the Honeywell sale closes.

Backup Generation Moves Into the Core

One of the notable shifts in the market is that backup generation is no longer only an insurance product for a small number of critical facilities. In the data center economy, redundancy and uptime are part of the commercial promise, and power systems are becoming central to site design, customer contracts, and speed to market.

That makes emissions control a strategic enabling layer rather than a narrow afterthought. If more projects rely on onsite or nearby thermal generation to bridge grid delays, support peak loads, or secure resilience, suppliers with proven catalyst systems can capture a larger share of value from the broader digital infrastructure build-out.

The Cormetech deal therefore broadens the usual definition of an AI-adjacent industrial investment. It is less about computing power itself than about the compliance, reliability, and permitting requirements that determine how quickly new computing capacity can be brought online.

Johnson Matthey’s Reset Starts to Look More Coherent

The acquisition also arrives at a delicate moment for Johnson Matthey’s own strategy. The group reported underlying operating profit of 340 million pounds for the year ended March 31, up 14% on an organic basis, and said it expects low to mid single-digit underlying operating profit growth in 2026-27 before contributions from Cormetech and before the effect of the Catalyst Technologies disposal.

In other words, the base business is improving, but the company is still being judged on whether its reshaping produces a simpler story with durable growth engines. Buying Cormetech gives management a way to show that capital from portfolio change is being recycled into an operating business with clearer industrial demand and nearer-term relevance.

Cormetech Acquisition After the Honeywell Sale

Johnson Matthey said the Honeywell transaction remains on track to close by the end of August 2026, after which it plans to return 1 billion pounds to shareholders. Even after the Cormetech purchase, the company said pro forma leverage would be about 1.8 times net debt to EBITDA and that it expects to move back toward its target range of 1.0 to 1.5 times by March 31, 2029.

That balance matters because investors are likely to view the Cormetech acquisition more favorably if it looks like disciplined reinvestment rather than a detour from simplification. Management is effectively arguing that it can both streamline the portfolio and selectively buy businesses that fit a tighter industrial thesis built around cleaner operations and practical infrastructure demand.

There is also a profitability angle. Johnson Matthey said combining Cormetech with Clean Air Solutions would create a business with more than 200 million pounds in annual sales and mid-teens operating margins in 2026-27. If that target holds, the acquired asset could help replace some of the earnings visibility investors worry about losing as the group exits larger but less focused operations.

What Investors Should Watch Next

The first question is execution. Johnson Matthey expects the deal to close around the end of June or in early July 2026, subject to customary approvals. Once that happens, investors will want to see whether the reported orderbook converts on schedule and whether the large data-center-linked pipeline turns into actual revenue rather than staying stuck in permitting or project design.

The second question is mix. A business exposed to stationary power generation can benefit from AI-related electricity demand, but it can also be sensitive to industrial capex cycles, utility interconnection delays, and shifts in emissions standards. Strong installed-base economics can soften that risk, yet it does not remove it.

The third question is strategic credibility. If Johnson Matthey can show that Cormetech strengthens cash generation, sharpens its industrial identity, and gives it a credible role in the power side of digital infrastructure, the acquisition will look like an intelligent repositioning move. If not, critics may see it as another mid-cycle portfolio adjustment. For now, the transaction suggests Johnson Matthey believes the next profitable edge in data center spending may sit as much in cleaner power hardware as in the chips inside the racks.

That is what makes this acquisition more than a routine chemicals-sector deal: it links industrial emissions technology to one of the fastest-moving infrastructure shifts in business today.
