IonQ Q3 2025 Earnings: Revenue Surges, Guidance Raised Despite Large Net Loss

November 5, 2025 · Published August 7, 2026

IonQ's revenue surged past its own prior guidance and its full-year outlook was raised, while the quarterly net loss reflected mostly non-cash, acquisition-related charges.

Figures as reported by the company to the SEC for the quarter ended September 30, 2025. Analyst estimates are not part of a filing, so no comparison to expectations is shown.

Key takeaways

• Revenue grew sharply from a year earlier and came in well above the high end of the range management had guided to last quarter, prompting the company to raise its full-year revenue outlook to $106–$110 million.
• The large quarterly net loss was driven mainly by non-cash charges tied to IonQ’s recent acquisitions of ion-trap firm Oxford Ionics and quantum-sensing company Vector Atomic, plus changes in the fair value of warrants and investments — not by a comparable jump in day-to-day operating spending.
• IonQ ended the quarter with $1.5 billion in cash and investments, which rose to about $3.5 billion on a pro forma basis after a $2 billion stock offering closed in mid-October, giving the company a large cushion to fund research and further deals.
• A trailing-year gross margin of roughly 36% means IonQ keeps about a third of each revenue dollar after direct costs, but the deeply negative operating margin shows spending on R&D, sales and administration still far exceeds revenue — typical of a company still in the early stages of commercializing its technology.
• The trailing-twelve-month net profit margin looks positive, but that mainly reflects one-time, non-cash accounting gains rather than actual profitability from the business — the quarter itself produced a substantial net loss.
• Alongside the financial results, management pointed to technical milestones, including reaching the company’s AQ 64 performance target three months ahead of schedule and reporting a world-record 99.99% fidelity for two-qubit gates.
• CEO Niccolo de Masi said IonQ “once again beat the high end of our revenue guidance, this time by 37%,” citing broader customer adoption of its quantum computing systems as a growth driver.

Q3 2025 in context

Figures for the quarter ended Sep 2025 and the quarter ended Sep 2024, as reported to the SEC.

How the stock took it

IONQ Inc closed at $53.38 on Nov 4, 2025, the last session before the report, and at $57.43 on Nov 6, 2025, the first session after it — +7.6% across the report.

Closes from the market's daily record. Each figure spans the report date — from the last session that closed before it to the first that closed after — because a company may report before the open or after the close.
