The "quantum computing" halo fails to offset the miss in fundamental growth! Rigetti (RGTI.US) fell more than 9% at one point after hours, with fidelity meeting targets but revenue missing expectations by 60%.

Rigetti Computing (RGTI.US), one of the most hyped "quantum computing concept stocks" in the U.S. stock market in recent years, released its Q3 2026 financial results for the period ended September 30, 2026 (covering July 1 to September 30) on the morning of November 11 Beijing time. The results showed that this tech company focused on quantum computing delivered on its technology milestones, but revenue fell far short of market consensus expectations, suffering major setbacks in revenue, losses, and order acceptance progress, causing the stock to fall more than 9% at one point in after-hours trading. As of the U.S. market close on November 10 Eastern Time, the stock closed down 6.63% at $12.12, with a cumulative decline of about 23% since the start of the fourth quarter. Rigetti's 108-qubit system achieved a median two-qubit gate fidelity of 99.5%, further validating the scalability of its chiplet architecture, but the technical progress has yet to stable revenue growth. The results showed that the company's third-quarter revenue was only $1.411 million, down 27.5% year-over-year and down 72.5% quarter-over-quarter, about 60% below the $3.52 million consensus estimate, and adjusted loss per share also fell short of expectations. The full-year revenue target of approximately $20 million still depends on the India C-DAC system passing acceptance in the fourth quarter. For the market, the next round of valuation support will depend on whether technology milestones can be converted more quickly into deliverable systems, customer acceptance, and sustained revenue. Revenue about 60% below expectations, R&D spending continues to push losses higher Financial data showed that Rigetti Computing's third-quarter revenue was $1.411 million, down 27.5% year-over-year and down 72.5% quarter-over-quarter, about 59.9% below the approximately $3.52 million Wall Street analyst consensus compiled by institutional sources. Adjusted loss per share was $0.06, compared with a loss of $0.03 in the year-ago period and a loss of $0.05 in the prior quarter, also worse than the analyst consensus of approximately $0.05. The company's cumulative revenue for the first three quarters was $10.949 million, up 109.8% year-over-year, with growth concentrated in the first half. The company's third-quarter gross profit was $857,000, up 112.1% year-over-year, with gross margin rising from 20.7% to 60.7%. The gross profit increment from the improved revenue mix was still insufficient to cover R&D expansion. R&D expenses rose 69.7% to $25.495 million, and operating loss widened 61.5% to $33.186 million. GAAP net loss narrowed from $201 million in the year-ago period to $3.137 million, including a $25.291 million gain from the fair value of warrants. Adjusted net loss was $20.468 million, up 92.2% year-over-year and up 28.1% quarter-over-quarter. Public information shows that Rigetti Computing's main business covers superconducting quantum processors, full systems, and quantum cloud services, with a technology stack spanning software and hardware from chip manufacturing to control systems. Its customers are mainly government laboratories, national research institutions, and corporate R&D departments. The high valuation the capital market has assigned to Rigetti is mainly built on these long-term application prospects; at this stage, revenue still depends on a small number of scientific research contracts and system deliveries. Some Wall Street institutional investors have even argued that quantum computing may be entering a stage similar to the early large AI models, and predict that this frontier technology will be the core engine of the "next-generation computing revolution." The theoretical foundation of quantum computing is quantum superposition, entanglement, and interference. A classical bit takes a value of 0 or 1, while a qubit can be in a superposition of both; multiple qubits form a joint state through entanglement, and algorithms use quantum gates to control interference and increase the probability of measuring the target result. Although describing the state of n qubits involves 2 basis states, this does not mean all answers can be read simultaneously, nor does it mean all tasks will be exponentially sped up. Its breakthrough potential is mainly reflected in specific problems such as molecular and materials simulation and large integer factorization; to complete long-duration, reliable computation, quantum error correction is also needed to organize error-prone physical qubits into reliable logical qubits. In the future, it is more likely to form a collaborative system of quantum computing and classical computing led by AI technology. 108 qubits meet target, full-year revenue still determined by customer acceptance The company expects 2026 revenue of approximately $20 million, conditional on the 108-qubit system of India's Centre for Development of Advanced Computing (C-DAC) passing acceptance in the fourth quarter and the related revenue being recognized. Based on actual revenue for the first three quarters, about $9.051 million in revenue needs to be achieved in the fourth quarter. The C-DAC order is worth $8.4 million, and the delivery and acceptance of this single contract has a major impact on full-year revenue. The volatility of quarterly revenue also reflects that commercialization is still in a stage driven by a small number of large projects. On the technology side, the important incremental development is that the Cepheus-1-108Q system, which uses 12 nine-qubit chiplets interconnected, saw median two-qubit gate fidelity rise from about 99.1% in the second quarter to 99.5%. A lower gate error rate helps support deeper computational circuits and reduces the error-correction burden. The next-stage goal is to achieve more than 300 qubits with about 99.7% fidelity by mid-2028, and to advance to about 1,000 qubits and 99.9% fidelity in about three years. Investment value depends on whether error rates, manufacturing costs, and system delivery cycles can continue to be controlled after scale expansion. Cash reserves support R&D, market valuation begins to question the pace of delivery As of the end of September, cash, cash equivalents, and available-for-sale investments totaled $497.1 million, down about 11.1% year-over-year and down 8.2% quarter-over-quarter, and the company has no debt. Operating cash outflow for the first three quarters was $49.061 million, up 12.4% year-over-year, and equipment purchase spending was $42.598 million, up 202.1% year-over-year. This also largely means the company still has funds to advance R&D, but cash investment in refrigeration, chip manufacturing, and full-system expansion is accelerating. Recent institutional adjustments also reflect this repricing. Before the earnings report, Wedbush maintained an outperform rating on November 5 but cut its target price from $37 to $25, citing reasons including lowered growth assumptions for 2027 and 2028. B. Riley maintained a buy rating on November 9 but cut its target price from $25 to $23. Based on the November 10 closing price and a static estimate of shares outstanding at the end of the third quarter, Rigetti's market value is still about $4.15 billion, equivalent to about 208 times its full-year revenue guidance. Such a valuation is highly sensitive to the pace of revenue recognition, and the time gap between technical progress, order acquisition, and acceptance delivery is precisely the core explanation for the recent sharp and extremely weak stock price volatility.
