IonQ Announces First Quarter 2026 Financial Results
Revenue Exceeds Midpoint of Guidance Range by 30%

COLLEGE PARK, MD – May 6, 2026 – IonQ (NYSE: IONQ), the world’s only full-stack quantum platform company, today announced financial results for the quarter ending March 31, 2026.

“I am pleased to share that IonQ has begun 2026 with strong momentum, delivering our fourth consecutive quarter of record-breaking results and the biggest quarter in our company's history - thus far. With $64.7 million in revenue, we have once again significantly outperformed our guidance range, exceeding the midpoint by 30%,” said Niccolo de Masi, Chairman and CEO. “As a result, we are raising our revenue expectations for the full year to $270 million at the high end, based upon the strong and growing demand for our leading quantum computers, as well as the commercial impact of our entire quantum platform.”

“Securing our first 256-qubit system sale and receiving our first ion trap chip samples back from the fab this quarter marks a pivotal shift toward commercial scale. We are now moving from component-level testing to integrated, system-level testing of the full 256-qubit quantum computer. These milestones, combined with the first-of-its-kind publication of our complete architectural blueprint for fault-tolerant quantum computing, prove that IonQ has the hardware and the roadmap to continually lead the quantum revolution. IonQ is poised to be the first company in history to fully demonstrate fault-tolerance at scale, and is already benefitting from leadership in real-world application time-to-solution.”

Niccolo de Masi continued, “We are executing and innovating across our quantum platform with key milestones this past quarter including: 1) DARPA’s selection of IonQ’s pioneering quantum interconnect technology to support heterogeneous quantum computing, 2) commercialization of our best-in-class sensing products, and 3) global deployments of our post-quantum cybersecurity solutions to ensure customers remain protected in the age of quantum ubiquity.”

Inder Singh, COO and CFO, added that “Our first quarter 2026 revenue was $64.7 million, representing 755% year-on-year growth, underpinned by accelerating global system sales, strong Tempo demand, strengthening pipeline, and increasing cloud utilization. I am proud to report that we saw not only record revenues, but an increase in our backlog as well. We delivered year-on-year growth across our product offerings, and this strong demand helped increase our reported RPOs by 554% year-on-year to a new record level of $470 million. I’m also pleased to report that our results reflected approximately 60% of revenue from commercial customers and approximately 35% from international customers. With this strong start to the year, we are raising our full year revenue guidance, reflecting our expectation of continued strong organic growth of 100% year-on-year or better.”

Inder Singh continued, “Our quantum platform strategy is resonating with customers, as illustrated by the fact that over one third of our revenue this quarter came from multi-product sales, not just computing. With a strengthened go-to-market team, we are implementing methodical pursuit and capture tactics and pursuing a land-and-expand strategy. We have now sold IonQ solutions in more than 30 countries, compared to a year ago when that number was only a few. As we look ahead into the rest of 2026, our focused pipeline, the expansion of our manufacturing capacity, the increase in our deployment resources, and the implementation of a corporate dashboard all help us maintain operational rigor and focus across our growing enterprise. We will continue to invest in bringing market-leading quantum products and applications to our customers.”

First Quarter and Recent Commercial Highlights

2026 Financial Outlook

*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 gain (loss) on change in fair value measurements, which are reconciling items between GAAP net income (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, changes in fair value from recurring fair value measurements (such as, warrant liabilities, contingent consideration, and investments), 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, changes in fair value from recurring fair value measurements (such as, of warrant liabilities, contingent consideration, and investments), 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.

Commercial and Organic Revenue

Commercial revenue includes all enterprise agreements with non-U.S. government customers including agreements with leading universities. Organic revenue is a supplemental measure representing revenue from the IonQ businesses comprising the consolidated company as of December 31, 2024, and excludes revenue from businesses acquired on or after January 1, 2025.

Remaining Performance Obligations

Remaining performance obligations (RPOs) represent the total transaction price from signed contracts that has been allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period. This includes both funded (firm orders for which funding has been authorized and appropriated) and unfunded (firm orders for which funding has not yet been appropriated) portions of the contract. Unexercised contract options are not included in remaining performance obligations until the time the option is exercised.
