We may issue securities from time to time in one or more offerings, in amounts, at prices and on terms determined at the time of offering. This prospectus describes the general terms of these securities and the general manner in which these securities will be offered. We will provide the specific terms of these securities in supplements to this prospectus, which will also describe the specific manner in which these securities will be offered and may also supplement, update or amend information contained in this prospectus. You should read this prospectus and any applicable prospectus supplement before you invest.

In addition, the selling stockholders to be named in a supplement to this prospectus may from time to time offer or sell shares of our common stock. To the extent that any selling stockholders resell any securities, the selling stockholders may be required to provide you with this prospectus and a prospectus supplement identifying and containing specific information about the selling stockholders and the amount and terms of the securities being offered. We will not receive any proceeds from the sale of our common stock by the selling stockholders.

The securities may be sold directly to you, through agents or through underwriters and dealers. If agents, underwriters or dealers are used to sell the securities, we will name them and describe their compensation in a prospectus supplement. The price to the public of those securities and the net proceeds we expect to receive from that sale will also be set forth in a prospectus supplement.

Our common stock and public warrants are listed on the New York Stock Exchange under the symbols “IONQ” and “IONQ.WS,” respectively. Each prospectus supplement will indicate whether the securities offered thereby will be listed on any securities exchange.

Please carefully read the information under the headings “ Risk Factors” beginning on page 4 of this prospectus and “Item 1A –Risk Factors” of our most recent report on Form 10-K or 10-Q that is incorporated by reference in this prospectus before you invest in our securities.
