Analysts covering IonQ, Inc. (NASDAQ: IONQ) have grown notably more cautious in recent weeks, slashing the consensus earnings-per-share estimate by 38.6% over the past 30 days alone.
The quantum computing company has beaten Wall Street’s EPS expectations just once across its last four reported quarters, a track record that gives investors limited reason for optimism heading into next week.
Most recently, IonQ missed badly, posting an actual loss of $0.33 per share against an expected loss of $0.29, a negative surprise of 13.79%.
Results for the quarter ended September 2026 are due on November 5, and the company is projected to report a loss of $0.30 per share for the period.
While that figure still represents a year-over-year improvement of 91.6%, the trajectory of analyst revisions suggests growing concern about near-term profitability.
Revenue expectations tell a more compelling story, with the consensus forecast calling for $145.29 million in quarterly sales, a 264.4% surge compared to the same period a year earlier.
Despite that dramatic top-line growth projection, IonQ’s Zacks Earnings ESP currently sits at -10.00%, meaning the Most Accurate Estimate trails the broader consensus, a signal that those closest to the data have turned more bearish.
The company also carries a Zacks Rank of 4, equivalent to a Sell rating, and that combination makes a positive earnings surprise particularly difficult to forecast with confidence.
Research from Zacks shows that stocks combining a positive Earnings ESP with a Zacks Rank of 1, 2, or 3 produce an upside earnings surprise nearly 70% of the time, a threshold IonQ currently falls well short of meeting.
By contrast, sector peer Advanced Micro Devices (NASDAQ: AMD) enters its own upcoming earnings report in considerably stronger shape, with an Earnings ESP of +2.55% and a Zacks Rank of 3.
AMD is expected to deliver earnings of $1.94 per share for the September 2026 quarter, a year-over-year jump of 61.7%, on revenues forecast at $13.12 billion, up 41.9% from a year ago.
Unlike IonQ, AMD has beaten consensus EPS estimates in each of its last four quarters, reinforcing its standing as the more reliable earnings performer between the two chip-era technology names.
For IonQ investors, the November 5 release will hinge not only on headline numbers but on management’s commentary around business conditions, customer momentum, and the path toward sustainable profitability.
With estimate revisions moving in the wrong direction and a weak surprise prediction signal, the burden of proof heading into this quarter falls squarely on IonQ’s leadership team.
