Quantinuum Trades 24% Below Its $60 IPO Price at a $12 Billion Value on $23 Million of Revenue

Quantinuum, the Honeywell-backed quantum computing company that listed on the Nasdaq in June, is a pre-profit business whose valuation rests almost entirely on future technology milestones. Its shares closed at $45.59 on Tuesday, October 6, about 24% below the $60 IPO price, giving a market cap of $12.11 billion against trailing revenue of $23 million. This Quantinuum stock analysis, based on Yahoo Finance data as of October 7, 2026, finds a large cash cushion but heavy losses and an extreme valuation, and our quantitative model does not issue a signal for the stock.

What Is Happening With the Stock Price

Quantinuum priced its initial public offering at $60 a share, raising about $1.7 billion in gross proceeds, and the stock opened at $68 on its first day of trading, June 4. Because the shares have only traded since then, the two-year range in our data covers about four months: on weekly closes it runs from $45.53 to $75.57, which puts the current price at the lower end, just above the low. On daily closes, the shares peaked at $83.17 in early July and are now about 45% below that level. Upcoming tests include the next quarterly report and the end of the 180-day lock-up on shares held by insiders and pre-IPO investors, around the start of December, which could add selling pressure.

Quality: Is This a Financially Sound Business?

Quality scores 48/100, a score that rests on the balance sheet rather than on profits. Quantinuum ended June with $2.1 billion of cash, cash equivalents and short-term investments, giving it a current ratio of 15.49, a quick ratio of 15.30 and debt-to-equity of 0.01. Profitability is deeply negative. Earnings per share are -$1.56 over the trailing twelve months, and return on assets, return on equity and net margin are N/A. The -6939.6% operating margin in our data reflects the second quarter alone, when a $555.0 million operating loss on $8.0 million of revenue included a large non-cash charge for stock-based compensation, recognized because the IPO met the vesting condition on earlier awards. Adjusted EBITDA, which excludes such charges, was a loss of $68.3 million. Yahoo’s trailing gross margin is 41.3%, but in the second quarter cost of revenue of $10.3 million exceeded revenue. Yahoo gives no free-cash-flow figure; in the first half, operating activities used $129.1 million and capital spending was $39.2 million.

Growth: Does This Company Have Real Upside?

Growth scores 49/100. Yahoo’s revenue growth figure of 279.4% matches the second quarter, when revenue rose to $8.0 million from $2.1 million a year earlier. That jump comes from a very small base, and revenue is lumpy: first-half revenue fell to $13.2 million from $21.2 million, and management’s 2026 guidance of $28 million to $32 million compares with about $31 million in 2025. Remaining performance obligations, contracted revenue not yet recognized, were $74.2 million at June 30. The longer-term case in this Quantinuum stock analysis rests on technology. The company says its Helios system has demonstrated near five-nines logical fidelity, with its next system, Sol, on track for 2027 and Apollo, its planned fault-tolerant machine, scheduled for 2029. Those timelines carry execution risk, and quantum computing has yet to show broad commercial demand.

Opportunity: Is Now a Good Time to Enter?

Opportunity is N/A. With no positive earnings (P/E is N/A), negative EBITDA (EV/EBITDA is -3.06) and no free-cash-flow figure, the only usable valuation measure is price-to-book of 3.99, and the model needs at least two before it scores this pillar. On revenue, the valuation is extreme. Yahoo lists EV/Revenue at 95.68, but that figure looks understated: market cap less June cash of $2.1 billion still leaves about $10 billion, more than 400 times trailing revenue. Quantinuum pays no dividend. The shares sit at the lower end of their short trading range and below the IPO price, but a falling share price does not by itself make a speculative stock cheap.

Quantinuum Stock Analysis: The Bottom Line

This Quantinuum stock analysis ends without a model signal. Quality scores 48/100 and Growth 49/100, but with Opportunity N/A there is not enough valuation evidence for a Buy, Hold or Sell rating, so the page shows N/A. The bull case: one of the best-funded companies in quantum computing, with $2.1 billion of cash, little debt, Honeywell’s backing and a hardware roadmap through 2029. The bear case: revenue is small, uneven and roughly flat on guidance, losses are large, and the market value is several hundred times revenue. Technical setbacks, competition from other quantum developers and large technology companies, and possible selling when the lock-up ends are all risks for a stock that is already about 45% below its daily-close peak.

StreetBriefs’ quantitative scoring model (Quality, Growth, Opportunity) issues a Buy, Hold or Sell signal only when all three pillars have adequate evidence. Any signal is a data-driven starting point for further research, not a personalized recommendation to transact.
