374Water revenue jumps 280% as OC San milestone drives Q2 results

374Water reported second-quarter 2026 revenue of $2.26 million, up about 280% from a year earlier, as completion of the Orange County Sanitation District Factory Acceptance Test unlocked revenue and more contract value. The company also cut operating losses, boosted gross margin to 87%, and said it is building out its Waste Destruction Services business and Orlando operations hub.

Why it matters: - 374Water is starting to convert commercial milestones into revenue, a key test for a company selling wastewater and waste-destruction technology. - The quarter showed stronger economics, with higher sales, improved margins and lower losses. - The company also said it is building the base for a recurring Waste Destruction Services business, which could broaden its revenue mix.

Between the lines: - The quarter suggests 374Water is moving from technical validation to execution, but the company is still early in scaling and remains loss-making. - The mix of municipal contracts, federal validation and partner-driven contracting points to a go-to-market strategy that leans on both government and commercial channels. - The improved margin and lower cash burn are helpful, but the balance sheet still looks tight with $1.8 million in cash at quarter end.

What's next: - 374Water expects the St. Cloud demonstration to conclude in September. - The OC San system is scheduled to be delivered in October. - The company expects to unlock additional contract value as more milestones are completed. - 374Water said it will keep building its WDS platform and Orlando infrastructure while executing existing municipal commitments.

The bottom line: - 374Water’s second quarter showed meaningful commercial traction, but the next test is turning that momentum into sustained revenue and repeatable operations.
