Management Commentary

“Rigetti delivered meaningful progress during the third quarter across system performance, technology development and strategic execution,” said Dr. Subodh Kulkarni, Rigetti CEO. “Our Cepheus-1-108Q system achieved our goal of 99.5% median two-qubit gate fidelity, demonstrating continued performance improvement at the 100-plus-qubit level and further validating our chiplet-based approach to scaling superconducting quantum computers.

“We also signed a definitive $100 million agreement with the U.S. Department of Commerce,” Dr. Kulkarni continued. “Building on the progress achieved this quarter, our next major system objective is to demonstrate a 300-plus-qubit system with approximately 99.7% median two-qubit gate fidelity and gate speeds below 60 nanoseconds by mid-2028.

Rigetti ended the third quarter of 2026 with a strong cash position and no debt, providing flexibility to continue investing in its technology roadmap and customer opportunities.

Business, Strategic and Technology Updates

Technology Performance and Roadmap

●	Rigetti’s superconducting systems continuously achieve gate speeds of 50-70 nanoseconds, which is about 10,000 times faster than trapped-ion systems and 100 times faster than neutral-atom systems.

●	Cepheus-1-108Q achieved 99.5% median two-qubit gate fidelity, meeting its performance milestone and further validating the Company’s chiplet architecture.

●	Cepheus-1-108Q achieved 99.6% median two-qubit gate fidelity on an 80 qubit sublattice and 99.7% median two-qubit gate fidelity on a 50 qubit sublattice.

●	Cepheus-1-108Q is based on 12 interconnected 9-qubit chiplets. The performance improvement reflects work across chip design, materials, fabrication, calibration and system engineering while preserving the Company’s modular architecture.

●	Rigetti is targeting a 300-plus-qubit system with approximately 99.7% median two-qubit gate fidelity and gate speeds below 60 nanoseconds by mid-2028. The system is expected to have a larger qubit count per chiplet, faster readout and expanded cryogenic capacity.

●

Rigetti continues to target a path toward systems with approximately 1,000 qubits, approximately 99.9% two-qubit gate fidelity, and gate speeds below 50 nanoseconds within approximately three years. The Company believes this combination of scale, fidelity and speed could provide a platform for demonstrating quantum advantage.

●

For the 1,000+ qubit system, Rigetti plans to increase the density of qubits in a single fridge as opposed to networking multiple fridges together. The Company believes this approach enables higher performance at a lower cost on the path toward building systems with thousands, and eventually tens of thousands, of qubits.

●	In support of its roadmap, the Company has continued investing in dilution refrigeration capacity and related infrastructure that can support higher-qubit-count systems. Rigetti believes its chiplet-based and open modular architecture provides a practical framework for scaling over time.

Definitive Agreement with the U.S. Department of Commerce

●	In September 2026, Rigetti signed a definitive agreement with the U.S. Department of Commerce for an award of up to $100 million under the CHIPS Research and Development Office Broad Agency Announcement pursuant to the CHIPS Act.

●

The award supports three research and development programs focused on miniaturized readout electronics, expanded cryogenic capacity through a new cryostat architecture, and fabrication capabilities for high-connectivity chip architectures. As a condition of the award, the Department received a minority, non-controlling equity stake in Rigetti.

Non-GAAP Financial Measures

To supplement Rigetti’s consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (GAAP), the Company uses certain non-GAAP financial measures: non-GAAP net loss, non-GAAP net loss per share attributable to common stockholders-basic and non-GAAP net loss per share attributable to common stockholders-diluted. The Company believes that providing these non-GAAP financial measures enhances the Company’s and investors’ ability to compare the Company’s past financial performance with its current performance. Non-GAAP net loss is defined as GAAP net loss excluding stock-based compensation expenses, change in fair value of derivative warrant liabilities and change in fair value of earn-out liabilities, non-GAAP net loss per share attributable to common stockholders-basic is defined as non-GAAP net loss divided by the weighted average shares used to compute net loss per share attributable to common stockholders-basic and non-GAAP net loss per share attributable to common stockholder-diluted is defined as non-GAAP net loss divided by the weighted average shares used to compute net loss per share attributable to common stockholders-diluted. The Company excludes stock-based compensation expenses, change in fair value of derivative warrant liabilities and change in fair value of earn-out liabilities from non-GAAP net loss, non-GAAP net loss per share attributable to common stockholders-basic and non-GAAP net loss per share attributable to common stockholders-diluted, primarily because these are non-cash items that the Company believes are not reflective of ongoing operating results and such items may not be comparable from period to period due to changes in the fair market value of the Company’s common stock, which is influenced by external factors such as the volatility of public markets and the performance of the Company’s peers. These non-GAAP financial measures, which are included in this press release and which may be referred to on the conference call discussing the Company’s third quarter financial results, are provided as supplemental information to the financial measures presented in this press release and discussed on the conference call that are calculated and presented in accordance with GAAP. Non-GAAP financial measures should not be considered a substitute for, or superior to, financial measures determined or calculated in accordance with GAAP. The Company’s definitions of its non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies. For a reconciliation of each non-GAAP financial measure to its most directly comparable GAAP measure, please refer to the reconciliation tables at the end of this press release.
