Growth has been driven by increasing customer uptake, repeat ordering and the expansion of distribution across key marine fuel hubs, strengthening the Company’s ability to scale across international fleets. The business has also continued to broaden its reach beyond marine, with growing engagement across land-based sectors. Marine The Marine sector remains the primary driver of growth, with Sulnox now engaged with c.100 shipping companies globally – almost double the number at the same time last year. Adoption spans a broad range of vessel types, including cruise ships, tankers, bulk carriers, containerships, gas carriers, passenger and offshore vessels – and across both conventional marine fuels and biofuels. Eastern Pacific Shipping, one of the world’s largest privately owned shipping companies, also increased its shareholding in the Company to 6.47% post period-end. A clear vote of confidence in our technology, and a powerful signal to the wider market. Further expansion has been supported by repeat ordering and wider fleet rollouts, extending into chartered and third-party managed fleets, including with previously announced operators such as Spring Marine and Crystal Cruises – reflecting growing confidence in both the operational and commercial benefits of the technology. This growth is also being supported by a strengthening industry backdrop, with tightening emissions regulation – including global measures such as the IMO’s Carbon Intensity Indicator (CII), and regional frameworks like those in the EU – alongside sustained fuel cost pressures, driving demand for practical, near-term efficiency solutions. Land-based opportunities Whilst Marine remains a key focus and revenue driver, it represents just c.5% of global oil consumption. Capital Access Group’s November 2025 research note estimated Sulnox’s addressable opportunity at c.17 million litres per day, which equates to a market opportunity of over £40bn. The majority of this opportunity sits across land-based sectors including mining, construction, rail, logistics, power generation and fuel retail, where similar pressures around fuel costs and emissions are driving demand for efficiency-led solutions. Reflecting this, Sulnox secured its first material deployment in the rail sector this financial year with Colas Rail UK, part of the Bouygues Group, adopting Sulnox Eco following successful evaluation, representing an important step into large-scale land-based applications. In recognition of this opportunity,
