Outlook: Guidance raised
IonQ now expects 2025 revenue of $106M–$110M (up from prior ranges disclosed earlier in the year). Management reaffirmed its Adjusted EBITDA loss midpoint for 2025 at ($206M)–($216M).
What drove the GAAP loss?

The reconciliation shows the loss was heavily impacted by non‑cash items, most notably an ~$882M change in the fair value of warrant liabilities, along with stock‑based compensation and acquisition‑related costs. These items explain the gap between GAAP EPS ($3.58) and Adjusted EPS ($0.17).
