(the "Company" or "Sulnox")

Asia presence strengthened with Vietnam patent 

(Aquis Stock Exchange: SNOX)

Sulnox, the greentech company delivering lower fuel costs and emissions with zero capex, is pleased to announce the grant of a patent in Vietnam, strengthening the Company's intellectual property protection as it expands its presence across Asia.

Consistent with Sulnox's more than 100 patents granted to date in other major markets, this latest patent for emulsification for Heavy Sulphur Fuel Oils (HSFO) and Sulnox Eco™ Fuel Conditioners which enhance all diesel, petrol/gasoline and biofuels, and marine fuels including Marine Gas Oil (MGO) and Marine Diesel Oil (MDO), Very and Ultra Low Sulphur Fuel Oils (VLSFO/ULSFO) and HSFO. 

Vietnam represents an important market for Sulnox, as the Company continues to expand its global reach into Asia in partnership with major distributors, and opens new stock locations. The country's proximity and connections to key centres such as Singapore, where Sulnox has become well established, as well as Indonesia and China, also reinforce the potential for supporting Asia's major industries and their closest supply chains.

Vietnam's energy transition agenda further reinforces the relevance of Sulnox's solutions. The government's "Journey to Net Zero" programme for 2025-2030, launched at the Green Trade Forum 2025 in Ho Chi Minh City, identifies the private sector as the primary delivery mechanism for emissions reduction, supported by favourable policy, green credit and a focus on environmental technology. As part of this transition, Vietnam is moving toward higher biofuel blends, including E10 gasoline, to reduce emissions and align with its net-zero commitment.

While biofuel blending delivers carbon benefits, higher ethanol content also introduces well-understood challenges around fuel stability, water absorption and efficiency - particularly across large fleets and storage -intensive industries. Sulnox Eco is specifically designed to address these challenges by conditioning blended fuels so they remain stable, efficient and compliant in real-world use, supporting both emissions reduction and operational reliability.

Ben Richardson, CEO of Sulnox, commented: 

"Backed by this timely addition to our intellectual property portfolio, we are excited to lend our expertise, experience and innovation to Vietnam's green transition. This is a fast growing market within Asia, with a forward-thinking mindset.  It represents an important new platform as we accelerate opportunities among large Asian industrial players struggling to meet tough sustainability goals while working hard to reduce fuel costs. We are encouraged by the potential of this strengthened foothold to deploy our zero-capex solutions at scale across the continent."
