Bull points
- Based on the strength of our performance so far in 2026, I am pleased to reiterate our guidance for this year, which can be seen on this slide, including full-year revenue and gross net guidance for Brent Supri and Eric Case.
- We believe this burn will continue to decline as company revenues ramp at a quicker pace than spending in the future.
- Importantly, we continue to believe we can achieve cash flow positivity without needing to access additional capital to support our existing business.
