IonQ

IonQ's Top Stability & Growth Strengths

Strong Revenue Growth: Recent quarters posted record revenue (e.g., $64.7M in Q1 and $80.1M in Q2 2026) alongside multiple raises to full‑year 2026 guidance. Remaining performance obligations also expanded materially, signaling contracted demand supporting future sales.
