Johnson Matthey completes sale of Catalyst Technologies to Honeywell

On 17 July 2026, Johnson Matthey plc (“JM”) completed the sale of its Catalyst Technologies (“CT”) business to Honeywell International Inc. (“Honeywell”) for an enterprise value of £1,325 million on a cash and debt-free basis. 

CT is a global provider of catalysts and process technologies that enable decarbonisation of the chemical and energy industries and the production of essential chemicals and sustainable fuels.  

JM expects to return £1billion of net sale proceeds to its shareholders, comprising £800 million through a special dividend with share consolidation, and £200 million through an on-market share buyback programme.  

The transaction represents a significant milestone for JM as it transforms into a focused, lean and cash generative group, underpinned by world-leading PGM expertise. 

The CT team has made a significant contribution to JM over the years and is set for continued success as part of Honeywell.
