GWH — ESS Tech, Inc. Dilution Risk Tracker

ESS Tech, Inc. (GWH) carries a DilutionScore of 77/100, placing it in the Critical dilution risk tier — the highest category tracked by DilutionWatch. Companies at this level typically have active capital-raising programs, compressed cash runway, or a combination of dilution vectors that together represent meaningful downside risk to share count. As of July 14, 2026, this score reflects real-time data pulled directly from SEC EDGAR filings.

GWH has an active ATM (at-the-market) program with $75.0M remaining capacity. ATM programs allow companies to sell shares continuously into the open market through a broker-dealer — without announcing a secondary offering. This creates a silent but steady source of share dilution that shows up in quarterly share count increases rather than a discrete offering event. Cash runway is a key watch item: GWH has approximately 3 months of runway at current burn rate. Companies with less than 18 months of runway are statistically more likely to file new shelf registrations or ATM programs within the next two quarters. DilutionWatch monitors SEC 10-Q filings to update this estimate each quarter.
