The offering provides a modest cash infusion (~$2.94M) but at the cost of 14.4% dilution, coming on the heels of a severe Q1 miss. With only $7.7M in cash and a ~$200K quarterly revenue run rate, the company will likely need additional capital within 12 months. Monitor for further dilution risk and any progress on the M1 burner order (delivery expected Q3 2026). The lock-up expiration in ~90 days could add overhang.
