## Exhibit 99.1

**Exhibit 99.1**

**Rigetti Signs Letter of Intent with U.S. Government for Quantum Computing Research**

*Rigetti announces that it has signed a letter of intent with the U.S. Department of Commerce for an award of up to $100 million to accelerate R&D projects addressing key technical challenges in scaling and advancing superconducting quantum computers.*

Berkeley, CA -- Rigetti Computing, Inc. (Nasdaq: RGTI) ("Rigetti" or the "Company"), a pioneer in full-stack quantum-classical computing, today announced that it has signed a letter of intent ("LOI") with the U.S. Department of Commerce (the "Department") for an award of up to $100 million in funding over three years to accelerate superconducting quantum computing R&D.

The funding is allocated under the CHIPS Research and Development Office Broad Agency Announcement pursuant to the CHIPS Act to grow U.S. leadership in emerging technologies, including quantum computing. The LOI contemplates that the Department will receive an equity stake in Rigetti consistent with the total amount of the funding. Under the LOI, Rigetti would pursue R&D projects that address major technical challenges in scaling and advancing superconducting quantum computing.

"Quantum computing will have far reaching impacts on our nation's national security, economic interests, and overall prosperity," said Dr. Subodh Kulkarni, Rigetti's CEO. "We are honored that the U.S. government is seeking to partner with Rigetti to accelerate the pace of quantum computing commercialization and to bolster U.S. leadership in this revolutionary field. This investment will allow us to tackle key scaling bottlenecks more rapidly and get us closer to utility-scale quantum computing."

"With today's CHIPS Research and Development investments in quantum computing, the Trump administration is leading the world into a new era of American innovation," said Secretary of Commerce Howard Lutnick. "These strategic quantum technology investments will build on our domestic industry, creating thousands of high-paying American jobs while advancing American quantum capabilities."

"The Department of Commerce's incentives strengthen and accelerate U.S. quantum leadership and technological resilience," said Bill Frauenhofer, Executive Director of Semiconductor Investment and Innovation. "Quantum computing has significant implications for national defense, advanced materials and biopharmaceutical discovery, financial modeling and energy systems."

**About Rigetti**

Rigetti is a pioneer in full-stack quantum computing. Rigetti quantum computers are based on superconducting qubits, which are widely believed to be the leading qubit modality given their maturity, clear path to scaling, and fast gate speeds. Rigetti quantum computing systems achieve gate speeds of 50-70 nanoseconds, which is about 1,000 times faster than alternative modalities such as trapped-ion and neutral-atom systems.

Rigetti sells on-premises 9-qubit to 108-qubit quantum computing systems, which support national laboratories and quantum computing centers. Rigetti's Cepheus 36-qubit to 108-qubit systems are based on the Company's proprietary chiplet-based technology and include the Company's control electronics. Rigetti's 9-qubit Novera QPU supports a broader R&D community with a high-performance, on-premises QPU designed to plug into a customer's existing cryogenic and control systems.

The Company operates quantum computers over the cloud through its Rigetti Quantum Cloud Services (QCS) platform, enabling global enterprise, government, and research clients to pursue R&D. The Company's proprietary quantum-classical infrastructure provides high-performance integration with public and private clouds for practical quantum computing.

Rigetti developed the industry's first multi-chip quantum processor for scalable quantum computing systems. Leveraging this proprietary technology, Rigetti deployed the industry's largest multi-chip quantum computer in 2026 with Cepheus-1-108Q, based on twelve 9-qubit chiplets tiled together. The Company designs and manufactures its chips in-house at Fab-1, the industry's first dedicated and integrated quantum device manufacturing facility. Learn more at <u>https://www.rigetti.com/</u>.
