Appointment of Three New Distributors

Kingdom of Saudi Arabia and Bahrain, Malaysia and Senegal

Metir plc (AIM: MET), the international provider of advanced water and environmental monitoring technologies, is pleased to announce the appointment of three new international distributors through its Modern Water subsidiary.

In the Kingdom of Saudi Arabia ("KSA") and Bahrain, Ali Salman Al Sinan has been appointed as an authorised distributor, further expanding the Group's presence in the Middle East Gulf region. The distributor will initially supply Modern Water's Microtox® LX and FX instruments.

The Middle East is an important region for water monitoring solutions, with countries such as KSA and Bahrain relying heavily on seawater desalination to meet water demand. Vision 2030 in KSA is a huge strategic programme, transformative in the water sector, with projects approaching one trillion USD in new water desalination, wastewater, and water recycling infrastructure. The goal for KSA is to increase desalination output to 50% of water demand and, eventually, to 90%, thereby reducing groundwater depletion.

In these environments, maintaining water quality and ensuring compliance with regulatory standards is critical across sectors, including municipal water, oil and gas, and industrial operations. Metir already has an established presence in the wider region, with Continuous Toxicity Monitoring ("CTM") units installed across multiple sites in Doha, Qatar.

Ali Salman Al Sinan, established in 2011, brings strong regional expertise, established customer relationships and a track record of delivering technical solutions in demanding operating environments. The company has extensive experience supporting clients across key sectors, including oil and gas, where monitoring requirements are often complex. In addition to supplying equipment, it provides technical consultancy, application support and after-sales service to support effective implementation and ongoing system performance.

In Malaysia, Greenson Technology Sdn. Bhd ("Greenson") has been appointed as an authorised distributor for Microtox® products in Malaysia, Indonesia and Brunei. Greenson, in addition to being a distributor of water-related technologies, is a well-established service provider for in-field water testing with real-time water quality data and intelligence. The appointment of Greenson will significantly expand Modern Water's presence in Asia.

In Senegal, West Africa, SENTECH has been appointed as an authorised distributor for Microtox® products. In Senegal, climate change has greatly increased water stress due to reduced groundwater availability and rising demand. The country is embarking on the "Great Water Transfer Project", which is expected to be completed in 2028, backed by over €250 million in World Bank and European Investment Bank funding. SENTECH is a leader in sensor and monitoring, and the design of sustainable drinking water systems, complementary with Microtox® technology.

In addition, the Group is in negotiations and close to appointing distributors in both the United Arab Emirates and Egypt, to supply Modern Water's Microtox® LX and FX instruments, further expanding its Middle East and North Africa regional footprint and creating additional channels for future commercial growth.

Bob Moore, Executive Chairman and Chief Executive Officer of Metir plc, commented:

"We are delighted with the progress of appointing three high-quality new authorised distributors in diverse growth regions for the Group, with more to come. Appointing Ali Salman Al Sinan as our authorised distributor in KSA and Bahrain marks an important step in expanding our presence in the Middle East Gulf region. Completing the appointment of authorised distributors in the United Arab Emirates and Egypt will further strengthen our footprint and pipeline of opportunities.

In addition, we are pleased with the appointment of Greenson for Malaysia, Indonesia, and Brunei, and SENTECH for Senegal as new authorised distributors. These appointments represent a breakthrough in two new regions with significant growth potential for the Group.

Starting with sales of Microtox® LX and FX units initially in these new distributor regions, we plan to market the supply of CTM units for regional, civil and industrial projects in due course.

We believe these developments position us well to support customers across key sectors, including desalination, oil and gas, and municipal water, and will support the Group's continued expansion in the Middle East, North and West Africa and Asia regions."
