IonQ (IONQ) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and IonQ published the results on November 5, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. IonQ reports EPS two ways: GAAP, under the accounting rules every US filer follows, and Adjusted EPS, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• The EPS here is diluted: $1.35. IonQ's release headline gives GAAP EPS of $1.42, which is basic EPS, and its Adjusted EPS of $(0.29) is reconciled from that basic figure.
• IonQ acquired SkyWater Technology on July 31, 2026, so the SkyWater Foundry Services segment has no year-ago revenue and includes two months. IonQ reports in thousands; figures here are in millions.

How IonQ splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• IonQ's IonQ Platform revenue was $90.3 million in Q3 2026, up 127% from $39.9 million in Q3 2025, 52% of total revenue.
• IonQ's SkyWater Foundry Services revenue was $83.5 million in Q3 2026, 48% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

In its Q3 2026 release, IonQ said:

“For the full year 2026, IonQ is raising its revenue guidance to between $505 million and $515 million.”

“For the full year, IonQ expects strong growth of 110% year-on-year in its quantum computing revenue”

This is the company's own guidance as of Nov 5, 2026, quoted as given. Walnut does not make forecasts of its own. Analyst estimates for the coming quarters are on the IONQ forecast page.

Revenue and diluted EPS for the last 5 quarters. Each date links to that quarter's release.

GAAP revenue and diluted EPS attributable to IonQ common stockholders, each as first reported in that quarter's release. IonQ's EPS swings between large profits and losses mainly because of the non-cash mark-to-market change in the fair value of its warrant liabilities.

We do not hold a confirmed date for IonQ's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Nov 5, 2026

IonQ's revenue was $173.8 million in Q3 2026, up 336% from $39.9 million. IonQ now reports two segments: IonQ Platform, with $90.3 million from external customers, and SkyWater Foundry Services, with $83.5 million. SkyWater joined on July 31, 2026, when IonQ acquired it for about $1,944.4 million of total consideration. (IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

Within IonQ Platform, quantum hardware revenue was $52.9 million, against $21.6 million, and quantum services $37.4 million, against $18.3 million. IonQ's release credits global deployments of its Tempo quantum computers and deliveries of quantum sensing and space-based products. (IonQ Form 10-Q, Q3 2026, Nov 5, 2026; IonQ Q3 2026 release, Nov 5, 2026)

SkyWater Foundry Services split into CMOS foundry revenue of $53.8 million and quantum foundry and advanced technologies of $29.8 million. The segment also booked $16.7 million of intersegment revenue from IonQ, which is eliminated in consolidation. (IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

IonQ's revenue is concentrated. One customer accounted for 30% of total revenue in Q3 2026, and in Q3 2025 three customers accounted for 61%. The United States was $136.3 million of the quarter's revenue and other international $37.5 million. (IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

Remaining performance obligations were about $1,168.0 million at September 30, 2026, and IonQ expects about 50% of that to be recognized as revenue within twelve months. (IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

IonQ reported Q3 2026 net income attributable to IonQ of $564.0 million, or $1.35 per diluted share, while its loss from operations widened to $(433,075) thousand. The profit came from a $896.2 million gain on the change in fair value of warrant liabilities, which the 10-Q attributes mainly to the effect of IonQ's stock price on its Series A and Series B warrants, and a $141.7 million income tax benefit tied to the SkyWater Acquisition. (IonQ Q3 2026 release, Nov 5, 2026; IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

Adjusted EPS was $(0.29), against $(0.17). It removes the fair value gains of $(857,178) thousand on a combined basis and adds back stock-based compensation of $146.9 million and acquisition transaction and integration costs of $42.7 million. IonQ reconciles Adjusted EPS from basic EPS of $1.42. (IonQ Q3 2026 release, Nov 5, 2026)

IonQ's depreciation and amortization rose to $127.6 million from $24.2 million, mainly because of $64.8 million of depreciation on acquired SkyWater Foundry Services fixed assets and $26.7 million of amortization of acquired intangible assets. Weighted average diluted shares were 400,865,291, against 294,524,786 a year earlier, and IonQ closed a $2.0 billion equity offering on October 16, 2026. (IonQ Q3 2026 release, Nov 5, 2026; IonQ Form 10-Q, Q3 2026, Nov 5, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

IonQ gives full-year revenue guidance in its release. With Q3 2026 results it raised 2026 revenue guidance to between $505 million and $515 million and said it expects quantum computing revenue to grow 110% year-on-year. It gives no earnings guidance. (IonQ Q3 2026 release, Nov 5, 2026)

The release headline says Q3 2026 revenue, GAAP EPS and Adjusted EPS all exceeded consensus estimates, without naming the consensus figures or their source. (IonQ Q3 2026 release, Nov 5, 2026)

A consensus figure is the average of the models published by the analysts who cover IonQ, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones IonQ's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning IONQ is on is IONQ a buy or a sell?, what analysts expect next is on the IONQ forecast, and what the company does is on the IonQ (IONQ) stock page.

Every number on this page can be traced to a document IonQ published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
