COLLEGE PARK, Md. and BLOOMINGTON, Minn. – January 26, 2026 – IonQ (NYSE: IONQ), the world’s leading quantum company, and SkyWater Technology (NASDAQ: SKYT), the largest exclusively U.S.-based, pure-play semiconductor foundry, today announced they have entered into a definitive agreement pursuant to which IonQ will acquire SkyWater for $35.00 per share in a cash-and-stock transaction, subject to a collar, implying a total equity value of approximately $1.8 billion.

“This transformational acquisition enables IonQ to materially accelerate its quantum computing roadmap and secure its fully scalable supply chain domestically. With secure, U.S.-based design, packaging and chip fabrication – IonQ will benefit from vertical integration across our increasingly interlinked quantum computing, quantum networking, quantum security, and quantum sensing applications for land, sea, air, and space,” said Niccolo de Masi, IonQ Chairman and Chief Executive Officer. “We are confident that uniting our revolutionary quantum platform with SkyWater’s leading capabilities in parallel innovation, engineering, and manufacturing, will accelerate America’s ability to deploy quantum technology for mission critical applications. This historic transaction will significantly accelerate commercialization of our fully fault-tolerant quantum computers and benefit our nation’s broader quantum industry, enhancing our national security, economic strength, and technological superiority.”

Mr. de Masi continued, “SkyWater is an unrivaled technology innovation partner, and with IonQ’s existing quantum sensing and quantum networking capabilities it will become the preeminent quantum merchant supplier under the continued leadership of Thomas Sonderman. Together, we remain committed to redefining what is possible for business, government, and society in the quantum era while unlocking long‑term value for shareholders of both companies.”

“This combination marks a pivotal moment in SkyWater’s evolution,” said Thomas Sonderman, Chief Executive Officer of SkyWater Technology. “As the largest pure-play 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 and manufacturing increasingly align. Joining forces with 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 merchant supplier of choice with an even broader set of quantum sensing and quantum networking solutions for all of our customers and partners.”

The combination of IonQ and SkyWater will create the first of its kind, vertically integrated quantum platform company. In addition to strengthening IonQ’s position as a trusted ecosystem partner and merchant supplier in aerospace and defense, the combined company will be positioned to continue delivering innovative breakthroughs for customers across industries, including pharmaceuticals, finance, and cloud and enterprise computing, among others. IonQ’s proprietary technology and architecture, combined with SkyWater’s world-class onshore R&D and manufacturing capabilities and differentiated development services, will create a full quantum ecosystem.

Following the close of the transaction, SkyWater will operate as a wholly owned subsidiary under the SkyWater name serving a full range of customers. Mr. Sonderman will lead the subsidiary and report to Mr. de Masi, which will ensure the continued delivery of industry-leading Advanced Technology Services, Wafer Services, and Advanced Packaging Services as well as atomic clocks and quantum interconnects to all SkyWater customers.

Transaction Rationale

• Accelerates Roadmap to Fault-Tolerant Quantum Computing: With SkyWater, IonQ strengthens its position as the only vertically integrated full-stack quantum platform company, with embedded access to a Trusted U.S. foundry. IonQ’s manufacturing timelines are expected to accelerate through reduced wafer iteration times and parallelizing wafer prototypes. As a result, the combined company is expected to pull forward functional testing of its 200,000 qubit QPUs in 2028 enabling over 8,000 ultra-high fidelity logical qubits. We believe that IonQ will be positioned as a core quantum computing, quantum networking, quantum security, and quantum sensing provider for the U.S. government, allies and partners. SkyWater will also help ensure accelerated innovation and high-quality manufacturability at scale and with industry-leading costs for IonQ’s technologies.
• Strengthens IonQ’s Position as a Trusted Government Partner with DMEA Category 1 Trusted Accreditation: The combination will support IonQ’s recently launched IonQ Federal division, supporting the federal and defense sectors with cutting-edge quantum solutions. Upon close, IonQ will have an end-to-end quantum supply chain in the U.S., from design and prototyping through manufacturing, packaging, deployment, and ongoing service upgrades. This will allow IonQ to securely support multiple important Department of War programs, such as the Microelectronics Commons network to support warfighter applications, and address critical national security vulnerabilities.
• Enables SkyWater to Continue Serving as a Semiconductor Foundry and Merchant Supplier: SkyWater remains committed to its current Aerospace and Defense and commercial markets and will continue as a pure-play global semiconductor foundry and merchant supplier, providing new and existing customers with the same high-quality standards they have come to expect. SkyWater will also deliver essential technology building blocks to other companies that are focused on advancing artificial intelligence, quantum computing, electrification, IoT, health diagnostics, and more. SkyWater will also be able to offer IonQ’s industry-leading quantum sensors and quantum networking solutions to SkyWater customers and partners.
• Brings Together Highly Talented Engineering Teams to Advance Innovation and Broaden Reach: We believe that IonQ and SkyWater have some of the most talented employees in the industry. The combined company’s employees will be uniquely capable of advancing technology to solve the world’s most complex problems and help ensure America prevails in the quantum era.
• Maintains Strong Balance Sheet to Facilitate Continued Growth: The cash and stock transaction structure allows IonQ to maintain ample runway for growth and preserve the Company’s financial flexibility to continue accelerating quantum commercialization.

Transaction Details

Under the terms of the agreement, SkyWater shareholders will receive $15.00 in cash and $20.00 in shares of IonQ common stock, subject to a collar, for each share of SkyWater common stock held at close of the transaction. The purchase price represents a 38.0% premium to the 30-day volume-weighted average price of SkyWater shares as of market close on January 23, 2026.

The stock component is subject to a collar under which SkyWater shareholders will receive IonQ stock valued at $20.00 per SkyWater share, based on the 20-day volume weighted average price of IonQ stock as of three business days before closing, unless such volume-weighted average is greater than $60.13 per share, in which case SkyWater shareholders will receive 0.3326 IonQ shares per SkyWater share, or less than $37.99 per share, in which case SkyWater shareholders will receive 0.5265 IonQ shares per SkyWater share.

SkyWater shareholders will own between 4.4% and 6.7% of the combined company under the collar. SkyWater will maintain its headquarters in Bloomington, Minnesota and its facilities in Minnesota, Florida, and Texas will serve as Regional Quantum Production Hubs.

The Boards of Directors of both companies have unanimously approved the transaction, which is expected to close in the second or third quarter of 2026, subject to approval by SkyWater shareholders, receipt of required regulatory approvals and satisfaction of other customary closing conditions.

In light of the pending transaction, SkyWater’s previously scheduled investor day will not be held in March 2026. The combined company is expected to hold an investor event in the third quarter of 2026.

IonQ 2025 Financial Outlook

IonQ expects to deliver full year 2025 revenue results at the high end or above its previously announced range of $106 million to $110 million when it reports its fourth quarter and full year 2025 earnings results next month.
