IonQ is no stranger to acquisitions, and now the quantum-computing company is set to add another company to its toolkit after agreeing to buy chip maker SkyWater Technology for $1.8 billion. IonQ will acquire the semiconductor foundry for $35 a share in a cash-and-stock transaction that is subject to a collar, or a financial safety net used to protect buyers and sellers from share-price fluctuations. The deal is expected to close in the second or third quarter of 2026 if approved by SkyWater shareholders and regulators.
