The PFAS Opportunity

A Global Environmental Issue

A Global Opportunity

• PFAS (known collectively as ‘forever chemicals’) are a family of man-made chemicals in use since 1950’s

• Contaminated sites include airports, defense bases, mines, fire & rescue stations and other industrial

• $250B+ addressable market in North America

• Increased funding globally. US, EU, Australia, Japan and others are implementing stricter PFAS limits, forcing utilities and industries to fast-track advanced treatment methods.

• Massive corporate liability events underline market opportunity.

• 3M Flanders agreement for €572 million remediation.

• 3M US$10.3 billion settlement with US government.

Delivering strong returns from FY25 investments, growing market share, and reinforcing our competitive position

==> picture [88 x 297] intentionally omitted <==

Pipeline Conversion – strong backlog across domestic and international markets, including delayed FY25 opportunities.

Margin Expansion – continued shift toward higher-margin proprietary chemistry and scalable water technologies.

Profitability - Water Technologies return to EBIDTA profit, legacy projects complete and delayed contracts commencing.

International Growth – revenue contribution from Europe PFAS contracts, US pilot projects and Singapore JV in price-sensitive markets.

Medium-term Upside – Near term headwinds in US O&G followed by significant opportunity from rising US shale gas production (12-18 months).

Addressing Complex Challenges in US Shale Production

Location : South Texas, USA Client : BlueChip Oil and Gas Operator Technology : CatChek

Solution

• CatChek - proprietary surfactant chemistry optimising proppant-formation interaction

• Field study: 1,735 wells (2021–2023) across multiple counties

Challenge

• Geological issues (clay swelling, fines migration) reduce well productivity

• Need cost-effective solution for prolific formations like Eagle Ford Basin

• Reduced water production, fines migration, corrosion; improved biocide performance

Results

• Up to 42% increase in oil production over 12 months

• 51% higher 3-month production rate vs. offset wells

• ▪ Low cost (1.4% of well cost) with high ROI ▪ Ongoing innovation with enhanced formulation (CatChek ENFLOW PM)
