Shares of IONQ Inc. plummeted 5.02% in after-hours trading on Wednesday, following the release of the quantum computing company's second-quarter earnings report. Despite beating revenue expectations, IonQ's wider-than-expected losses appeared to disappoint investors.

IonQ reported a Q2 loss of $0.70 per diluted share, significantly wider than the $0.18 loss reported in the same quarter last year and far exceeding the $0.29 loss analysts had forecasted. However, the company's revenue performance was more positive, with Q2 revenue reaching $20.7 million, up from $11.4 million a year earlier and surpassing the analyst consensus estimate of $17.2 million.

Looking ahead, IonQ provided an optimistic outlook. The company expects Q3 revenue between $25 million and $29 million, in line with analyst expectations of $25.5 million. Moreover, IonQ raised its full-year 2025 revenue guidance to a range of $82 million to $100 million, up from its previous forecast of $75 million to $95 million. CEO Niccolo de Masi expressed satisfaction with the company's performance, noting that Q2 revenue beat the top end of guidance by 15%. Despite the positive revenue outlook, the market's after-hours reaction suggests investors may be more focused on the company's widening losses in the near term.
