What to Expect From IonQ’s Q4 Performance
IonQ’s third-quarter revenues of $39.9 million were up 222% year over year and 37% above the high end of its guidance. The company stated that fourth-quarter 2025 revenues are expected to exceed the Q3 levels, breaking the seasonality seen in prior years. The company also raised its full-year 2025 revenue outlook to $106-$110 million.
During the third quarter of 2025, IonQ strengthened its position as a full-stack quantum platform provider. The company closed its acquisition of Oxford Ionics, expanding its quantum computing capabilities. During the quarter, IonQ also delivered #AQ 64 on its Tempo system ahead of schedule and achieved a record 99.99% two-qubit gate fidelity milestone. After the quarter ended, IonQ closed its acquisition of Vector Atomic and raised $2 billion in October, bringing pro forma liquidity to approximately $3.5 billion and significantly strengthening its financial flexibility. All these are expected to have contributed positively to IONQ’s fourth-quarter performance.
At the same time, investment remains heavy. IonQ’s third-quarter operating expenses were $208.7 million, with R&D at $66.3 million and an adjusted EBITDA loss of $48.9 million. Full-year EBITDA guidance remains at a loss of $206–$216 million, signaling continued aggressive spending.
However, despite strong operational progress and raised revenue guidance, IonQ’s stock declined during the October–December quarter. The pullback occurred amid broader market volatility in high-growth technology stocks. While IonQ continues to expand its exposure to government and sovereign contracts, near-term equity performance may remain sensitive to broader market conditions.
Competitive Positioning
Rigetti Computing (RGTI - Free Report) : In the fourth quarter of 2025, Rigetti Computing is expected to have witnessed continued execution on its system roadmap rather than a sharp revenue inflection. With $5.7 million in purchase orders for two Novera quantum systems scheduled for delivery in the first half of 2026, fourth-quarter revenues are likely to remain modest, with greater contribution expected next year. Investors will focus on progress toward the planned 100+ qubit chiplet-based system, fidelity improvements and updates on additional system orders. The stock carries a Zacks Rank #3 (Hold).
D-Wave Quantum (QBTS - Free Report) : In the fourth quarter of 2025, D-Wave’s performance is expected to have built on its recent booking momentum rather than show an immediate step-change in recognized revenue. The company announced a 10 million euro booking tied to partial capacity of its Advantage2 system under a multiyear agreement, which is likely to have supported backlog growth more than near-term revenues. Continued enterprise and research partnerships may have strengthened demand visibility. The stock carries a Zacks Rank #3.
What the Zacks Model Unveils for IONQ Stock
Our proven model does not conclusively predict an earnings beat for IonQ this time. The combination of a positive Earnings ESP and a Zacks Rank #1 (Strong Buy), 2 (Buy) or 3 (Hold) increases the odds of an earnings beat, which is not the case here.
Earnings ESP: IonQ has an Earnings ESP of 0.00%. You can uncover the best stocks before they’re reported with our Earnings ESP Filter.
The stock is currently trading at a lofty forward 12-month price-to-sales (P/S) ratio of 53.55, which is significantly higher than the industry average of 4.8. This exceptionally high forward P/S ratio raises the risk of a sharp pullback if fourth-quarter results or the guidance for 2026 disappoint.

Our Take
IonQ’s strong third-quarter performance, raised full-year revenue outlook and expectation for stronger fourth-quarter revenues signal solid commercial execution. The company also boosted liquidity following its October capital raise. However, the adjusted EBITDA losses projection of $206–$216 million for 2025 reflects continued heavy investment. With tech-sector volatility pressuring the stock, investors may prefer to stay cautious ahead of the fourth-quarter earnings release, consistent with its Zacks Rank.
