Honeywell completes £1.325bn acquisition of Johnson Matthey’s Catalyst Technologies business

Honeywell Technologies has completed its all-cash acquisition of Johnson Matthey’s Catalyst Technologies business for £1.325bn, strengthening its position across refining, petrochemicals and renewable fuels.

The deal gives Honeywell Technologies a broader, more integrated offering for customers across energy and process technologies, layered on top of its existing automation and digital capabilities. It also extends the company’s global installed base and its ability to serve a wider range of industrial applications, reinforcing a push toward integrated solutions that improve efficiency and performance across the value chain.

“This acquisition significantly enhances Honeywell Technologies’ ability to deliver end-to-end solutions that help our customers drive efficiency, reduce emissions and accelerate energy security goals,” said Ken West, President and CEO, Process Technology, Honeywell Technologies. “By combining Johnson Matthey’s differentiated catalyst expertise with our leading technologies and digital capabilities, we are creating a strong platform for future growth while enabling our customers to immediately unlock the benefits of a more robust set of offerings.”

The acquisition closes shortly after Honeywell Technologies separated its Aerospace Technologies business, which now trades independently as Honeywell Aerospace as of June 29, 2026, following the October 2025 spin-off of Advanced Materials business Solstice Advanced Materials. Since 2023, Honeywell has completed roughly $11.5 billion in accretive acquisitions.
