Analysis · QSI · Industrial Applications And Services
Quantum-Si's Q2 2026 10-Q confirms a deteriorating financial position: revenue fell 42% year-over-year to $344,000 as customers defer purchases ahead of the delayed Proteus platform. The company now expects Proteus to launch in Q2 2027, a six-month slip from the prior end-of-2026 target, and is cutting 20% of its workforce to preserve cash. With $169.9 million in cash and securities, management believes it has at least 12 months of runway, but the Nasdaq delisting notice and continued operating losses raise serious concerns about the company's ability to reach commercialization without further dilution.
