NPK International, a Texas-based worksite access company listed on the New York Stock Exchange, has acquired Essex-headquartered Grassform Plant Hire for £35.2m. Grassform, with bases in Ingatestone, Essex, and Worksop, Nottinghamshire, specialises in supplying and installing temporary roadways, trackway access roads and site compound areas, operating a fleet of more than 20,000 composite mats.
For the year ended 31 October 2025, Grassform reported revenue of £15m and EBITDA of £6m. The acquisition brings the Essex firm into NPK International’s UK operations, complementing its existing business and expanding its geographic coverage.
Matthew Lanigan, president and chief executive of NPK, said: “We are excited to welcome the Grassform team to NPK and are confident that the acquisition will meaningfully strengthen our UK operations through scale and the addition of a highly tenured and talented team. The acquisition significantly expands our market coverage and is highly complementary to our existing UK operations.”
Lanigan added that the transaction aligns with NPK’s growth strategy, which prioritises scaling its high-return rental business through geographic expansion and increased market share within its core rental and service offerings. He highlighted the opportunities in the UK market, supported by a robust outlook for infrastructure investments over the coming years.
“Further, with limited debt following the transaction, we remain well positioned to continue executing on our disciplined capital allocation strategy, which prioritises investment in organic growth and strategic inorganic opportunities, balanced with the programmatic return of capital,” Lanigan said.
