IonQ Completes Acquisition of SkyWater Technology

Key Terms

fault-tolerant quantum computing technical

Fault-tolerant quantum computing is the ability of a quantum computer to keep producing correct results even when its basic parts make mistakes, by detecting and fixing errors and using redundancy so the machine continues to work reliably. For investors, it matters because fault tolerance is the key to scaling quantum machines from experimental demos into practical, revenue-generating systems—think of it like having backups and automatic repairs that make a prototype road-ready and lower the technology’s commercial and technical risk.

semiconductor foundry technical

A semiconductor foundry is a specialized factory that manufactures silicon chips used in electronic devices. These foundries produce chips designed by other companies, acting like a contract manufacturer for complex electronic components. Investors pay attention to them because their capacity and efficiency can influence the supply of vital technology products and impact the broader electronics market.

two-qubit gate fidelity technical

Two-qubit gate fidelity measures how accurately a quantum computer performs a basic operation that links two quantum bits (qubits). Think of it like the success rate of a two-person handshake that must be precise for a larger task; higher fidelity means fewer errors, better chances of running useful algorithms, and lower cost to correct mistakes. Investors watch it because higher fidelity signals more reliable hardware and faster progress toward commercially valuable quantum computing.

atomic clocks technical

Atomic clocks are extremely precise timekeepers that measure seconds by counting the natural vibrations of atoms, like a metronome so steady it hardly ever drifts. For investors they matter because accurate timestamps and synchronized networks support high-speed trading, satellite navigation, communications and regulatory record-keeping—mistimed data or outages can lead to lost trades, compliance problems or market disruptions that affect asset values.

quantum interconnects technical

Quantum interconnects are the hardware and links that carry quantum information between parts of a quantum computer or between separate quantum devices, like the bridges and cables that let different pieces of a machine share data without losing the fragile quantum state. They matter to investors because reliable interconnects determine whether quantum systems can grow from lab demos into practical, scalable products; better interconnects speed commercialization, increase potential market size, and protect the value of related patents and partnerships.

Creates the Only Vertically Integrated Full-Stack Quantum Platform Company

Accelerates IonQ’s Fault-Tolerant Quantum Computing Roadmap

Facilitates Secure End-to-End Design through Delivery of IonQ’s Platform of Next-Generation Quantum Computing, Quantum Networking, Quantum Security, and Quantum Sensing Technologies

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

COLLEGE PARK, Md. & BLOOMINGTON, Minn.--(BUSINESS WIRE)-- 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.

Transaction Details

Under the terms of the agreement, SkyWater shareholders are receiving $15.00 in cash and 0.4883 shares of IonQ common stock for each share of SkyWater common stock held at close of the transaction. The closing followed receipt of required regulatory approvals. The combined company is expected to hold its second quarter earnings call on Wednesday, Aug. 5, 2026 after the U.S. market closes and an investor day in the third quarter of 2026 (Sept. 8).
