Its Palantir partnership could generate over $100M in incremental annual revenue in the coming years, although commercialization remains at an early stage. Management raised FY2026 guidance: Revenue is now expected at $1.853B–$1.857B, above the $1.82B consensus. Adj EBITDA guidance increased to $414.1M–$415.2M, and FCF guidance rose to $270.6M–$271.6M. Q4 underlying revenue growth guidance of 23% implies deceleration from Q3's 30%. Shares outstanding increased 5.3% YoY, highlighting dilution concerns.
