374Water says preliminary revenue higher in Q2 after key sanitation district contract milestone
374Water Inc (NASDAQ:SCWO) said preliminary Q2 2026 revenue rose to over $2.2 million from $0.6 million a year earlier, mainly from revenue recognized after a Factory Acceptance Test milestone for California’s Orange County Sanitation District (OC San). The milestone enables recognition of remaining $1.1 million and $2.6 million in remaining billings. Full results are due Aug. 14.
How this was made
The 30-second read
Why it matters
Completion of the OC San Factory Acceptance Test is a gating milestone that allows revenue recognition and sets up subsequent phases, which can improve near-term reported revenue and expectations for remaining billings.
Market read
The update is a milestone-driven revenue catalyst ahead of the company’s scheduled Aug 14 full Q2 results, with most Q2 revenue tied to OC San.
What to watch
The article does not quantify margins, cash burn, or backlog quality; investors may focus on whether the Orlando facility expansion and mobile system pilots translate into durable recurring revenue.
Background
374Water develops supercritical water oxidation technology (AirSCWO) for destroying organic waste including PFAS, with revenue tied to project milestones and commissioning steps.
Ticker impact
374Water reports preliminary Q2 revenue above $2.2M, driven by revenue recognized after completing OC San Factory Acceptance Test.
Shares may see a positive bias into the Aug 14 full-results release as investors price in higher recognized revenue and milestone progression.
The article provides concrete preliminary revenue figures and ties the majority of Q2 revenue to a specific milestone, plus indicates remaining revenue and billings tied to subsequent operational milestones.
Market effects
