Simply Wall St · 1d ago

IonQ (IONQ) shares climbed about 9% after the company closed its roughly US$1.8 billion acquisition of SkyWater Technology, a US-based semiconductor foundry that will now operate as an IonQ subsidiary.

The SkyWater deal arrives during a mixed period for IonQ’s stock, with a 7 day share price return of 10.96% but a 30 day share price return that is down 29.11%. Over longer horizons, total shareholder return sits slightly lower over 1 year at a decline of 4.41%, but remains very large over 3 and 5 years. This points to momentum that has cooled recently even as interest in quantum computing headlines stays high.

After a sharp rebound and with the SkyWater deal now closed, the key issue for IonQ investors is simple. Has most of the easy upside already played out, or does the current valuation still leave meaningful room ahead?

Most Popular Narrative: 24.1% Undervalued

IonQ’s most followed narrative assigns a fair value of $48.00 per share, compared with the last close of $36.44. That gap is what the current debate turns on.

The biggest update is that IonQ’s latest quarter reinforced its position as the most commercially scaled of the public quantum names. The company said Q1 revenue exceeded the midpoint of guidance by 30%, and Reuters reported that the raise in guidance reflected increasing demand for its platform. That matters because revenue scale is one of the few hard ways to separate the better quantum equities from the more conceptual ones.

Want to understand why this narrative still sees upside in IonQ at a premium stock price? It leans heavily on accelerating revenue, ambitious platform expansion and a confident profit profile that assumes meaningful progress from here.

According to HedgeY, the narrative rests on IonQ already crossing $100 million of annual revenue, guiding to a much higher top line, and targeting a broad quantum platform that spans computing, networking, sensing and manufacturing. It also assumes that a very large cash balance and sizeable contracted backlog help support a premium market value despite the company still prioritizing growth over earnings.

Result: Fair Value of $48.00 (UNDERVALUED)

However, IonQ’s premium stock price and continued losses mean that any stumble in technology progress or acquisition integration could quickly challenge this undervalued narrative.
