Rigetti (RGTI) Q4 2025 earnings review

Technical Milestones Hit, But Revenue Lags as R&D Burn Accelerates

Rigetti ended FY25 as a pre-commercial R&D entity with a massive $589.8M war chest, effectively de-risking its balance sheet for years. Q4 2025 revenue came in at just $1.9M (down 18% YoY), capping a year where total sales fell 34% due to the expiration of early government funding initiatives. However, operating losses widened to $22.6M in Q4 as R&D investments accelerated. The real story lies in technical execution: Rigetti hit 99.9% two-qubit gate fidelity on a prototype and successfully demonstrated its modular chiplet scaling with a 108-qubit system. Backlog is finally building, with management guiding for 'significant' revenue growth in Q1 2026 fueled by $5.7M in Novera system shipments.

🐂 Bull Case

On-Premises Sales Validating Hardware

The company has secured substantial purchase orders, including an $8.4M system for India's C-DAC and $5.7M in Novera systems. This marks a vital shift from government research grants to direct commercial hardware deployment.

Massive Capital Runway

Following Q2's massive ATM raise and strategic investments, the company sits on $589.8M in cash and investments. Against a FY25 operating cash burn of ~$58.5M, Rigetti has an unprecedented multi-year runway to achieve quantum advantage.

🐻 Bear Case

Rising Operational Burn

Q4 operating loss accelerated to $22.6M from $18.5M a year prior, driven heavily by increasing R&D expenses. As the company scales to larger fabs and more complex chipsets, the cash drain will likely continue accelerating.

Fidelity Penalty at Scale

While 99.9% fidelity was hit on a prototype, maintaining this precision across higher qubit counts remains difficult. The 108-qubit system currently demonstrates a 99.0% median fidelity, showing that scaling still introduces meaningful error rate penalties.

⚖️ Verdict: ⚪

Neutral. As an R&D pure-play, the widening operating losses and YoY revenue declines are secondary to the massive liquidity profile and technical milestones. The true test comes in H1 2026, when Rigetti transitions from selling single QPU prototypes to shipping full, multi-million dollar on-premises 108-qubit systems.

Key Themes

DRIVERNEW🟢

Hardware Shipments Becoming the Primary Growth Engine

Rigetti is successfully translating academic and institutional interest into multi-million dollar backlog. The recent $8.4M order from India's Centre for Development of Advanced Computing (C-DAC) for a 108-qubit system joins the $5.7M in Novera orders expected to be delivered in H1 2026. This validates the shift toward selling deployable, hybrid classical-quantum infrastructure rather than relying solely on cloud access or government R&D grants.

DRIVER🟢🟢

Chiplet Tiling Proves Out as a Viable Scale Architecture

Management successfully demonstrated that the 108-qubit chiplet system (Cepheus-1-108Q) is functioning, hitting a 99.0% median two-qubit gate fidelity. During testing, they resolved tunable-coupler interactions that emerge at higher qubit counts. This affirms that their proprietary multi-chip tiling strategy—where proven smaller blocks are combined rather than creating massive monolithic chips—is the defining technical path forward for the company.

THEME🔴

Staggering Cash Runway Provides Maximum Optionality

Rigetti holds a commanding $589.8M in cash, cash equivalents, and available-for-sale investments with zero debt. This is up substantially from $217M at the end of FY24, primarily due to aggressive At-The-Market (ATM) and warrant issuances earlier in the year. In an industry defined by massive capital intensity and 3-5 year timelines to commercialization, this balance sheet operates as a fortress.

CONCERNNEW🔴

Accelerating R&D Burn and Margin Erosion

R&D expense accelerated significantly in Q4 to $17.3M (up 27% YoY). Full-year gross profit dropped precipitously from $5.7M in FY24 to just $2.1M in FY25, highlighting that current lower-margin revenue streams (such as the UK NQCC deal) provide minimal offset to the soaring costs of designing more complex, tightly integrated chiplets.

CONCERNNEW🔴

Fidelity Decay at Higher Qubit Counts

While Rigetti proudly announced hitting 99.9% fidelity on a prototype, the actual deployed systems show a steady decay as complexity grows: 9-qubit hits 99.7%, 36-qubit hits 99.6%, and the 108-qubit system hits 99.0%. Since achieving 'quantum advantage' requires 99.9% fidelity across 1,000+ qubits, this degradation curve indicates fault tolerance is still a highly distant target.

Other KPIs

FY25 Net Cash Used in Operating Activities$58.5 million

Stable compared to $50.6 million used in FY24. Given the $589.8M liquidity pile, the current operational cash burn gives Rigetti nearly a decade of runway assuming costs remain linear, though capital expenditures (CapEx) for next-generation fabrication will likely increase total burn.

FY25 Research and Development Expense$61.3 million

Accelerating significantly from $49.8 million in FY24. As Rigetti pivots from 36-qubit to 108-qubit scaling and deepens integration testing for advanced error correction with Riverlane, intellectual property protection, fabrication, and engineering headcount costs are visibly escalating.

FY25 Net Loss (GAAP)$216.2 million

Widened from a $201.0 million loss in FY24. However, GAAP net loss for Rigetti includes massive, volatile non-cash adjustments. In FY25, the change in fair value of derivative warrant liabilities alone constituted a $150.6 million non-cash charge. Non-GAAP net loss of $50.5 million reflects a far more stable underlying operational reality.

Guidance

Q1 2026 Revenue GrowthSignificant YoY Increase

Accelerating dramatically. With Q1 2025 revenue having been a meager $1.47M, management anticipates substantial growth driven by partial fulfillment of the $5.7M Novera on-premises purchase orders.

108-Qubit C-DAC System DeploymentSecond Half of 2026

This ~$8.4M purchase order from the Centre for Development of Advanced Computing will be the cornerstone revenue event for late FY26. It further embeds Rigetti's hybrid architecture within high-performance, international computing environments.

Japanese Research Novera DeliveryApril 2026

This scheduled delivery opens Rigetti's first Quantum Processing Unit footprint in Japan, marking further international adoption of its hardware for academic and strategic R&D usage.

Key Questions

Margin Profile on Institutional Hardware Sales

With the $8.4M C-DAC order and $5.7M Novera backlog scheduled for 2026 delivery, how should we expect gross margins to trend compared to the severely compressed 31-35% margins seen throughout FY25 on government R&D contracts?

Scaling Tiling to 150+ Qubits

Management identified and mitigated tunable-coupler interactions in the 108-qubit system. Are these same coupler interference issues expected to scale exponentially as you target 150+ qubits, or is the current architectural refinement considered a definitive fix for the mid-term roadmap?

Fab-1 Upgrade Timeline

In previous calls, you noted the eventual necessity to upgrade to a 200mm or 300mm fab to push fidelity past 99.9%, costing hundreds of millions. Given the current $589M cash balance, are plans for this heavy CapEx cycle being accelerated, or are you still awaiting external validation like the NQI Reauthorization?
