("SkyWater") disposed of pursuant to the consummation of the transactions contemplated by the Agreement and Plan of Merger (the "Merger Agreement"), dated as of January 25, 2026, by and among SkyWater, IonQ, Inc. ("IonQ"), Merger Subsidiary 1 Inc. ("Merger Subsidiary 1"), and Iris Merger Subsidiary 2 LLC (now known as SkyWater Technology, LLC) ("Surviving Company"), including the merger of Iris Merger Subsidiary 1 with and into SkyWater (the "First Merger"), immediately followed by the merger of SkyWater with and into Surviving Company (the "Second Merger"). At the effective time of the First Merger (the "Effective Time"), each share of SkyWater common stock outstanding immediately prior to the Effective Time (subject to certain exceptions described in the Merger Agreement) automatically converted into the right to receive $15 in cash and 0.4883 shares of common stock of IonQ plus cash in lieu of any fractional shares.

Pursuant to the Merger Agreement, at the Effective Time, each award of restricted stock units relating to shares of SkyWater common stock held by a service provider other than a non-employee member of SkyWater's board of directors that was outstanding, whether vested or unvested, automatically converted into a restricted stock unit award corresponding to a number of shares of IonQ common stock based on the Equity Award Exchange Ratio (as defined in the Merger Agreement), and is otherwise subject to the same terms and conditions (including any existing accelerated vesting provisions) as applied immediately prior to the Effective Time, with any related accrued but unpaid dividend equivalent rights carrying over and remaining payable in accordance with such preexisting terms.
(3)	Represents options to purchase shares of SkyWater common stock. Pursuant to the Merger Agreement, at the Effective Time, each outstanding option to purchase shares of SkyWater common stock that was outstanding, whether vested or unvested, automatically converted into an option to purchase a number of shares of IonQ common stock based on the Equity Award Exchange Ratio (as defined in the Merger Agreement), at an adjusted exercise price (as determined in accordance with the formula in the Merger Agreement), and is otherwise subject to the same terms and conditions as applied immediately prior to the Effective Time.
(4)	Prior to the Effective Time, the options were scheduled to vest ratably on each of the first, second, third and fourth anniversaries of the grant date contingent on the reporting person's continuation in service on each applicable vesting date.
