Company Overview
Founded by quantum physics pioneers from the University of Maryland and Duke University in 2015, IonQ (NYSE:IONQ) develops quantum computers that process information using trapped ions to solve complex computational problems beyond the capabilities of traditional computers.
Revenue Growth
A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years.
With $246.5 million in revenue over the past 12 months, IonQ is a small player in the business services space, which sometimes brings disadvantages compared to larger competitors benefiting from economies of scale and numerous distribution channels. On the bright side, it can grow faster because it has more room to expand.
As you can see below, IonQ grew its sales at an incredible 267% compounded annual growth rate over the last five years. This is an encouraging starting point for our analysis because it shows IonQ’s demand was higher than many business services companies.
Long-term growth is the most important, but within business services, a half-decade historical view may miss new innovations or demand cycles. IonQ’s annualized revenue growth of 181% over the last two years is below its five-year trend, but we still think the results suggest healthy demand. 
This quarter, IonQ reported magnificent year-on-year revenue growth of 287%, and its $80.05 million of revenue beat Wall Street’s estimates by 20.4%.
Looking ahead, sell-side analysts expect revenue to grow 25.3% over the next 12 months, a deceleration versus the last two years. Despite the slowdown, this projection is commendable and implies the market is baking in success for its products and services.

Adjusted Operating Margin
Adjusted operating margin is one of the best measures of profitability because it tells us how much money a company takes home after subtracting all core expenses, like marketing and R&D. It also removes various one-time costs to paint a better picture of normalized profits.
IonQ’s high expenses have contributed to an average adjusted operating margin of negative 268% over the last five years. Unprofitable business services companies require extra attention because they could get caught swimming naked when the tide goes out.
On the plus side, IonQ’s adjusted operating margin rose over the last five years, as its sales growth gave it operating leverage. Still, it will take much more for the company to reach long-term profitability.
In Q2, IonQ generated a negative 244% adjusted operating margin.
Earnings Per Share
We track the long-term change in earnings per share (EPS) for the same reason as long-term revenue growth. Compared to revenue, however, EPS highlights whether a company’s growth is profitable.
IonQ’s earnings losses deepened over the last four years as its EPS dropped 33.9% annually. We’ll keep a close eye on the company as diminishing earnings could imply changing secular trends and preferences.
Like with revenue, we analyze EPS over a shorter period to see if we are missing a change in the business.
For IonQ, its two-year annual EPS declines of 9.7% show it’s still underperforming. These results were bad no matter how you slice the data, but given it was successful in other measures of financial health, we’re hopeful IonQ can generate earnings growth in the future.
In Q2, IonQ reported adjusted EPS of negative $0.33, down from negative $0.14 in the same quarter last year. This print missed analysts’ estimates. Over the next 12 months, Wall Street expects IonQ to perform poorly. Analysts forecast its full-year EPS will tumble from negative $1.04 to negative $1.21.
Key Takeaways from IonQ’s Q2 Results
