Honeywell announced on 9 June 2025 the completion of its acquisition of Sundyne from private equity firm Warburg Pincus for $2.16 billion in an all-cash transaction.
The acquisition of Sundyne—a provider of design, manufacturing and aftermarket support of highly-engineered pumps and gas compressors for process industries is expected to be immediately accretive to Honeywell’s sales growth and segment margins as well as to adjusted EPS in the first full year of ownership.
Sundyne’s customer relationships, products and technology will help to unlock strategic growth potential for Honeywell UOP’s value chains in refining and petrochemicals, liquefied natural gas (LNG) and clean and renewable fuels.
Ken West, President and CEO of Honeywell‘s Energy and Sustainability Solutions (ESS) segment said: “Merging Sundyne’s differentiated products with Honeywell’s leading technology and R&D capabilities positions our business for significant growth.
“By enhancing our end-to-end process technology and critical equipment offerings, this acquisition allows us to provide improved solutions for our customers.”
The completion of this acquisition follows Honeywell’s announcement of the planned spin-offs of its Aerospace Technologies and Solstice Advanced Materials businesses, which will result in three publicly listed industry leaders with strategies and growth drivers.
Since December 2023, Honeywell has announced a number of strategic actions to drive organic growth and simplify its portfolio, including $13.5 billion of accretive acquisitions.
In addition to Sundyne, these acquisitions include: the Access Solutions business from Carrier Global, Civitanavi Systems, CAES Systems, the LNG business from Air Products and Johnson Matthey’s Catalyst Technologies Business.
Honeywell also completed the sale of its Personal Protective Equipment business to Protective Industrial Products last month.
Honeywell has announced the complete acquisition of Sundyne, a decision that intends to strengthen its process industry capabilities.
