(“SkyWater”), is filing these Post-Effective Amendments (the “Post-Effective Amendments”) to the following Registration Statements on Form S-8 (each, a “Registration Statement”), previously filed with the Securities and Exchange Commission (the “Commission”), to withdraw and remove from registration any and all shares (“Shares”) of SkyWater’s common stock, par value $0.01 per share, plan interests and other securities that remain unsold or otherwise unissued under each Registration Statement:

•

Registration Statement No. 333-275414 filed with the Commission on November 9, 2023, relating to the registration of 4,222,000 Shares authorized for issuance under the SkyWater Technology, Inc. 2021 Equity Incentive Plan (the “EIP”) and 750,000 Shares authorized for issuance under the SkyWater Technology, Inc. 2021 Employee Stock Purchase Plan (the “ESPP”).

•

Registration Statement No. 333-255414 filed with the Commission on April 21, 2021, relating to the registration of 5,000,000 Shares authorized for issuance under the Registrant’s EIP and 700,000 Shares authorized for issuance under the Registrant’s ESPP.

Reference is made to the previously announced Agreement and Plan of Merger, dated as of January 25, 2026 (the “Merger Agreement”) by and among the Registrant, SkyWater, IonQ, Inc. (“IonQ”), and Iris Merger Subsidiary 1 Inc., a direct, wholly owned subsidiary of IonQ (“Merger Subsidiary 1”).

On July 31, 2026, pursuant to the Merger Agreement, (i) Merger Subsidiary 1 merged with and into SkyWater (the “First Merger”), with SkyWater surviving the First Merger as a direct, wholly owned subsidiary of IonQ, and (ii) immediately following the First Merger, SkyWater merged with and into the Registrant (the “Second Merger” and, together with the First Merger, the “Mergers”), with the Registrant surviving the Second Merger as a wholly owned subsidiary of IonQ. At the effective time of the Second Merger, the Registrant was renamed “SkyWater Technology, LLC”.

As a result of the consummation of the Mergers, the Registrant has terminated all offerings of its securities pursuant to each Registration Statement as of the effective time of the Mergers on July 31, 2026. In accordance with an undertaking made by the Registrant in each Registration Statement to remove from registration, by means of a post-effective amendment, any securities which remain unsold or unissued at the termination of the offering, the Registrant hereby removes and withdraws from registration all securities of the Registrant registered pursuant to any Registration Statement that remain unsold or otherwise unissued as of the date hereof. Each Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities, and the Registrant hereby terminates the effectiveness of such Registration Statement.
