Washington governor directs $500K to IonQ's quantum computing facility expansion in Bothell

Governor Bob Ferguson has directed $500,000 from Washington's Economic Development Strategic Reserve Fund to support IonQ's expansion in Bothell. The quantum computing manufacturer, whose largest shareholders include Vanguard, BlackRock and Morgan Stanley Investment Management, will use the funding for building upgrades, workforce expenses and expansion costs. The state funding is matched by over $14 million in private investment. IonQ opened the nation's first dedicated quantum computing manufacturing facility in Bothell in 2024, which has since expanded into a 100,000-square-foot hub. The expansion is expected to create between 1,200 and 2,000 jobs over five years. IonQ develops quantum computing systems for complex problems in healthcare, energy and cybersecurity. The Strategic Reserve Fund uses unclaimed lottery prize money for economic development projects.

IonQ appoints William F. Scannell as director amid $1.8B SkyWater acquisition

IonQ has appointed William F. Scannell as a Class II director, with a term running until the 2026 Annual Meeting and a seat on the Compensation Committee. The appointment comes as the quantum computing company reports strong year-over-year revenue growth and pursues vertical integration of its quantum hardware platform. The board expansion follows IonQ's announcement of a $1.8 billion acquisition of SkyWater Technology, aimed at creating a vertically integrated quantum hardware stack. The deal supports IonQ's roadmap towards 256-qubit chip-based systems, though it also raises concerns about acquisition costs and integration complexity. IonQ's narrative projects $388.6 million in revenue by 2028, requiring 69.5% annual revenue growth. However, the company faces ongoing challenges including cash burn, acquisition spending and widening adjusted EBITDA losses as it works to scale its trapped ion quantum computing technology.
