IonQ, Inc.

Item 1.01 Entry into a Material Definitive Agreement. On October 9, 2026, IonQ, Inc., a Delaware corporation (the “Company”), Espresso Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of the Company (the “Merger Sub”), Elisity, Inc., a Delaware corporation (“Elisity”), and Fortis Advisors LLC, solely in its capacity as the representative of the securityholders, entered into an Agreement and Plan of Merger (the “Agreement”) pursuant to which the Company has agreed to acquire all of the issued and outstanding shares of Elisity (the “Transaction”). Pursuant to the terms of the Agreement and subject to the satisfaction or waiver of certain conditions set forth in the Agreement, the aggregate consideration payable by the Company to Elisity’s securityholders at the closing (the “Closing”) of the Transaction (the “Closing Consideration”) consists of a number of shares of the Company’s common stock, par value $0.0001 per share (each, a “Share”), with a value of $1,150,000,000. The Closing Consideration will be reduced by any leakage (other than customary permitted leakage exceptions) incurred by Elisity since July 31, 2026, as further described in the Agreement. The final number of Shares to be issued as Closing Consideration will be calculated using the volume-weighted average price for Shares for the 20 trading days immediately preceding, but not including, the third business day prior to the date of the Closing, but will not be more than $49.61 per Share, nor less than $33.07 per Share (the “Common Stock Price”). In addition to the Closing Consideration, Elisity’s securityholders will be eligible to receive a number of Shares with a value of up to an additional $150,000,000 of consideration, calculated using the Common Stock Price (the “Earnout Consideration” and, together with the Closing Consideration, the “Merger Consideration”), based on certain revenue milestones achieved by Elisity from August 1, 2026 to January 31, 2028. Under the Agreement, the Company has also agreed to establish a retention pool for continuing employees of Elisity consisting of a number of restricted stock units with respect to Shares (“RSUs”) determined by dividing $100,000,000 by the Common Stock Price. The RSUs will be granted following the Closing, will vest over four years and are in addition to the Merger Consideration. The Agreement contains customary representations, warranties, covenants and other obligations and rights of the parties thereto. The Agreement also specifies the treatment of outstanding Elisity options and equity awards in connection with the Transaction. The parties to the Agreement have also agreed to various customary covenants and agreements, including, among others, for Elisity to conduct, subject to certain exceptions, its business in the ordinary course consistent with past practice during the period between the execution of the Agreement and the Closing. The completion of the Transaction is subject to the satisfaction of customary closing conditions, including, among other things, the absence of any governmental law or order that makes the Transaction illegal or otherwise prohibits or prevents its consummation; the obtainment, expiration or termination (as applicable) of certain regulatory approvals imposed by governmental entities; the accuracy of the representations and warranties made by the parties to the Agreement (subject to customary materiality thresholds); the absence of a material adverse effect on Elisity; and the authorization for listing on the New York Stock Exchange of the Shares to be issued as Closing Consideration. The Agreement may be terminated under certain circumstances, including, but not limited to, by mutual written agreement of the Company and Elisity and, subject to certain conditions, if the Closing shall not have occurred by January 7, 2027. The foregoing description of the Transaction and the Agreement does not purport to be complete and is qualified in its entirety by reference to the Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Agreement has been filed to provide investors and securityholders with information regarding its terms.
