SkyWater Will Continue to Serve Customers as a U.S.-based Semiconductor Foundry

IonQ (NYSE:IONQ), the world’s leading quantum platform company, today completed its acquisition of SkyWater Technology (NASDAQ:SKYT), the largest exclusively U.S.-based semiconductor foundry.

"Acquiring SkyWater crystalizes IonQ’s vision to serve as a technology leader, merchant supplier and ecosystem enabler across the entire quantum industry. We are investing in capabilities from quantum foundry and advanced packaging to manufacturing and commercialization that the quantum ecosystem requires for future growth," said Niccolo de Masi, Chairman and Chief Executive Officer of IonQ. "Building upon our existing merchant supplier track record providing quantum solutions for our customers, we expect this acquisition to accelerate all quantum platforms across the industry."

"This combination enables IonQ to drive our quantum computing roadmap and secure a fully scalable supply chain domestically. It unlocks IonQ‘s semiconductor-based approach to manufacturing new generations of our quantum computers, while ensuring SkyWater’s ability to deliver the excellent quality and attention customers expect," said de Masi, who added, "Secure chip design, fabrication, and packaging will deliver vertical integration across our full stack of quantum applications for land, sea, air, and space."

"Joining the IonQ team marks a pivotal moment in SkyWater’s evolution," said Thomas Sonderman, Chief Executive Officer of SkyWater Technology. "As the largest semiconductor foundry based in the U.S., SkyWater is already the partner of choice for advanced development and manufacturing services in both the public and private sectors as quantum computing shifts from research to manufacturing. Being part of IonQ will accelerate multiple engineering pathways for next-generation quantum chips, delivering speed, precision, and scale. Importantly, SkyWater remains fully committed to all of our semiconductor foundry customers and will continue as the quantum supplier of choice with an even broader set of quantum sensing and quantum networking solutions for our customers and partners."

Following today’s closing, SkyWater will operate as a subsidiary under the SkyWater name. Sonderman will lead the subsidiary and report to de Masi, which will ensure the continued delivery of industry-leading Advanced Technology, Wafer, and Advanced Packaging Services as well as atomic clocks and quantum interconnects to all SkyWater customers.
