SulNOx Group Plc (the "Company" or "SulNOx")

First order Costa Rica and additional large order in Germany

(Aquis Stock Exchange: SNOX)

The board of the directors of the Company (the "Board") is pleased to announce, further sales of its SulNOxEco™️ Fuel Conditioner product through master distributor A&S International ("A&S").

Swiss Fuel Services have now purchased an additional intermediate bulk container of circa 1,000 litres of SulNOxEco™️ Fuel Conditioner, just 1 month after the last significant order. This further repeat purchase follows the commencement of the first of several large-scale shipping evaluations on one of three tankers from a fleet of >40 vessels. Swiss Fuel Services have conservatively estimated that they will purchase a further 9,000 litres of SulNOx in 2022 and additional, larger orders expected in 2023.

SulNOx have also sold product into Costa Rica for the first time. Another sub-distributor of A&S, Central de Mangueras ("CDM") has made an initial purchase for evaluations with their clients. CDM is an industrial and automotive company, established four decades ago, serving the entire national territory from 12 branches. It has more than 200 collaborators and a unit of sales consultants who visit the main companies in Costa Rica. CDM's points of sale include more than 20 strategic partners who are responsible for the distribution of products.

Ben Richardson, CEO of SulNOx commented, "Costa Rica has often been celebrated as an environmental leader and one of the most sustainable countries in the world. SulNOx have already supplied conservationist, Captain Pete Bethune, famous for his disruption of Japanese whaling activities and founder of Earthrace Conservation with product to support the Government Environmental Agency SINAC in various campaigns protecting Costa Rica's national parks. We are therefore thrilled that A&S continues to expand the sales of SulNOx to their global network and very pleased to partner with CDM and help deliver Costa Rica's decarbonisation agenda."

Gustavo Munoz, Commercial Director at CDM, said of the initial order, "We are delighted to purchase our first SulNOx stock. CDM are specialists in providing Integral Solutions that add value to the operation of our clients. We stimulate industry, agriculture, construction and free zones, in addition to the country's automotive industry with high-tech products. As a natural and green, biodegradable solution to reducing emissions, SulNOx will play an important part in our product portfolio for our clients."
