374Water (SCWO) Investor presentation summary

Commercial model and deployments

• Three revenue channels: recurring fee-for-service destruction at WDS hubs, mobile on-site campaigns, and AirSCWO equipment sales with commissioning and operations.

• Orlando WDS hub was completing construction as the first waste destruction site; the Arcadis collaboration envisages using it for AFFF destruction.

• St. Cloud’s $600K mobile contract was completed in September 2026; four feedstocks were processed and all campaign phases finished without operational issues.

• OC San passed its factory acceptance test in Q2 2026, with deployment planned for November; Olathe has a ~$4.8M equipment and operations order advancing toward delivery.

Technology and validation

• AirSCWO uses supercritical water oxidation above 374°C and 221 bar to convert organic compounds into minerals and gases.

• Independent ERDC validation found 99.9993% total PFAS destruction and removal across 42 compounds; treated effluent met EPA limits for regulated PFAS.

• Validation reported near-zero fluorinated stack emissions; AirSCWO has processed 200+ waste types.

• Mobile systems support customer-site campaigns; modular systems expand capacity by adding modules at permanent sites and hubs.

Markets and regulatory drivers

• AFFF and rinsate inventories across federal, industrial and municipal owners are estimated at ~10M gallons, with additional PFAS concentrates and spent media generated by treatment systems.

• U.S. wastewater plants generate ~16,000 dry tons of biosolids per day; state restrictions and pressure on hauling and disposal are driving regional coalitions.

• PFOA and PFOS hazardous-substance designations were upheld in August 2026; federal, state and EU regulatory initiatives add pressure for PFAS remediation and destruction.

• Other target streams include hazardous organic, pharmaceutical, hydrocarbon, munitions, battery-recycling and food wastes; customer work has covered oil and gas, chemical, pulp and paper, and pharmaceutical streams.
