Sulnox Group (LSE:SNOX) said in a trading update that it delivered record full-year revenue of £2,623k for the year to 31 March, up 134% on £1,121k a year earlier, and a record fourth-quarter revenue of £929k, up 97% year-on-year.
Growth was driven by repeat sales and wider adoption across global marine markets, with Sulnox, a fuel-conditioning and oil-reclamation technology company, engaged with c.100 shipping companies (up from 55 at March 2025) and expanding into land-based sectors including rail.
"With growing adoption, expanding distribution and strong repeat ordering from customers, we are well positioned to continue building momentum through 2026," said Ben Richardson, CEO.
Independent laboratory testing confirmed Sulnox Eco's compatibility across the expanded ISO8217 marine fuel standard including biofuels and showed c.28% improvement in lubricity in HVO, a threefold improvement in oxidative stability in neat B100 and a "technically significant" reduction in steel pitting in untreated B100.
Commercial reach has been extended by a long-term global agreement with Drew Marine, regional distribution deals, 11 stock points in key bunkering hubs and six new patents taking protection to more than 100 markets. Cash was £822k at 31 March (versus £1,122k at 31 December 2025) and the company raised £2m post period-end, with management saying momentum has continued into the first quarter of the new financial year.
