Metir PLC (AIM:MET), the water and environmental monitoring company, has made its first commercial sale of a PFAS detection unit in the United States, with shares jumping 33% to 0.9p on the news.
The buyer is Veralto, a Nasdaq-listed water quality business with a market capitalisation of $20 billion, which has taken the unit on a lease-to-purchase basis and is expected to deploy it within its water quality operations, with a view to broader market deployment across its global client base.
PFAS, short for polyfluorinated alkyl substances and commonly known as "forever chemicals", are a family of thousands of persistent synthetic compounds found across industrial, agricultural and consumer applications, including historically in firefighting foams used extensively in the aviation sector.
Alongside the Veralto deal, Metir announced a cluster of developments designed to accelerate the commercial rollout of its PFAS detection platform across the UK, Europe and the US.
In the UK, the company is in discussions with ProDecon Services, a PFAS decontamination specialist, over a joint field-testing programme expected to begin in the third quarter of 2026, which will generate operational data to support further platform development.
In Europe, Metir has signed a memorandum of understanding with FIDCHEM, a Spanish water treatment technology developer, to co-develop artificial intelligence and machine learning software capable of simplifying the interpretation of PFAS data output, reducing the operational skill level required to use the platform below that of a specialist mass spectrometer operator.
Metir has also agreed to acquire sole ownership of the intellectual property underlying its PFAS measurement method, developed over three and a half years in collaboration with Swansea University.
The company said it is evaluating applications in semiconductor manufacturing, an industry that uses PFAS chemicals extensively across approximately 1,500 to 1,600 wafer fabrication facilities worldwide, where compliance requirements are tightening.
The commercial push comes against a backdrop of intensifying regulatory pressure, with a new EU law on water quality standards entering into force on 11 May 2026 and UK environmental agencies having identified more than 1,500 confirmed PFAS-contaminated sites, with up to 10,000 high-risk locations potentially requiring remediation.
The global PFAS testing market is projected to reach $969.5 million by 2030.
