IonQ (NYSE: IONQ), the world’s leading quantum company, today announced financial results for the quarter ended September 30, 2025.

"I am pleased to report that we once again beat the high end of our revenue guidance, this time by 37%. We are also raising our revenue expectations for the full year to $110 million at the high end of guidance,” said Niccolo de Masi, Chairman and CEO of IonQ. “We delivered our 2025 technical milestone of #AQ 64 three months early, unlocking 36 quadrillion times more computational space than leading commercial superconducting systems. We achieved a truly historic milestone by demonstrating world-record 99.99% two-qubit gate performance, underscoring our path to 2 million qubits and 80,000 logical qubits in 2030.”

“Our technical achievements continue to solidify IonQ’s quantum platform as the most complete and powerful in the world, with a correspondingly larger addressable global market,” de Masi continued. “Our Electronic Qubit Control systems and world-record fidelity, combined with uniquely low unit economics at full fault tolerance, underpin IonQ as the global leader in a class of its own in quantum computing. Meanwhile, we are on a clear trajectory to deliver critical quantum cybersecurity infrastructure, ultra-precise quantum navigation, quantum timing solutions, and large-scale networked quantum systems.”

de Masi concluded, “Now with $3.5 billion of pro-forma net cash, we are continuing to reap the compounding benefits of our scale and momentum advantages, entrenching our position as the dominant force in quantum and the only complete platform solution. I am confident in our ability to deliver growth and value creation for IonQ shareholders in 2026.”

*Adjusted EBITDA is a non-GAAP financial measure defined under “Non-GAAP Financial Measures,” below. The Company is unable to provide a reconciliation of forward-looking Adjusted EBITDA without unreasonable effort because of the uncertainty and potential variability in amount and timing of certain charges, including the change in the fair value of warrant liabilities, which are reconciling items between GAAP net loss and Adjusted EBITDA and could significantly impact GAAP results.

Non-GAAP Financial Measures

To supplement IonQ’s condensed consolidated financial statements presented in accordance with GAAP, IonQ uses non-GAAP measures of certain components of financial performance. Adjusted EBITDA and Adjusted EPS are financial measures that are not required by or presented in accordance with GAAP. Management believes that these measures provide investors additional meaningful methods to evaluate certain aspects of the Company’s results period over period.

Adjusted EBITDA is defined as net loss attributable to IonQ, Inc. before net loss attributable to noncontrolling interests, interest income, interest expense, income tax (benefit) expense, depreciation and amortization, stock-based compensation, executive cash-based severance, change in fair value of warrant liabilities, offering costs associated with warrants and acquisition transaction and integration costs. Adjusted EPS is defined as earnings per share, or EPS, excluding the impact of stock-based compensation, executive cash-based severance, change in fair value of warrant liabilities, offering costs associated with warrants and acquisition transaction and integration costs. IonQ uses Adjusted EBITDA and Adjusted EPS to measure the operating performance of its business, excluding specifically identified items that it does not believe directly reflect its core operations and that may not be indicative of recurring operations.

The presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for the financial results prepared in accordance with GAAP, and IonQ’s non-GAAP measures may be different from non-GAAP measures used by other companies. IonQ shows a reconciliation of its non-GAAP measures to the most directly comparable GAAP measures at the end of this release.
