IonQ Announces Second Quarter Financial Results

COLLEGE PARK, Md.--(BUSINESS WIRE)-- IonQ (NYSE: IONQ), the leading commercial quantum computing and networking company, today announced financial results for the quarter ended June 30, 2025.

"I am pleased to report that we beat the top end of guidance for Q2 revenue by 15%, and strengthened our balance sheet via the largest equity investment from a single institution in the quantum industry. We also made very tangible progress towards delivering our #AQ64 application performance benchmark, with strong indications that it will be achieved in the near term.”

“Via our closed acquisition of Lightsynq, along with our proposed acquisition of Oxford Ionics, we have created the most advanced and powerful quantum computing and networking roadmap in the world," said Niccolo de Masi, Chairman and CEO of IonQ. "The combination of IonQ hardware and software expertise and Oxford's implementation of ion-trap-on-a-chip provides the team, IP, technology, and momentum to achieve 800 logical qubits in 2027 and 80,000 logical qubits in 2030."

“The close of our acquisition of Capella in July expands our quantum networking vision to include a space-based QKD network," de Masi continued. “Our networking products are production-grade and are used by many of the world's household-name financial services, telecom, and government agencies. IonQ quantum networking offers the ultimate in communication security, protecting even from the looming threat of quantum decryption."

"We’ve also attracted world-class leaders who are choosing to build the future at IonQ. From the world of finance, Dr. Marco Pistoia has joined us after leading global applied research and quantum computing at JPMorgan Chase. From the highest levels of government, we welcomed Dr. Rick Muller, former Director of IARPA, the intelligence community’s advanced research agency. To guide our corporate growth, veteran technology counsel Paul Dacier has taken the helm as Chief Legal Officer, and to sharpen our scientific core, our co-founder Dr. Chris Monroe has assumed the vital role of Chief Scientific Advisor.”

“As I have said before, I believe talent is the proverbial Warren Buffett weighing machine most relevant to any company's long-term prospects, and it is tremendously validating to have such towering figures in the quantum industry become our colleagues at IonQ."

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 is a financial measure that is not required by or presented in accordance with GAAP. Management believes that this measure provides investors an additional meaningful method 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 expense, stock-based compensation, change in fair value of assumed warrant liabilities, acquisition transaction costs, and other non-recurring non-operating income and expenses. IonQ uses Adjusted EBITDA to measure the operating performance of its business, excluding specifically identified items that it does not believe directly reflect its core operations and may not be indicative of recurring operations. The presentation of 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 GAAP to non-GAAP financial measures at the end of this release.
