Most Popular Narrative: 51% Undervalued

Quantinuum's last close at $40.57 sits well below the analyst consensus Narrative fair value of $83.00, pointing to a large valuation gap built on long range quantum and AI expectations. The analyst consensus Narrative on Simply Wall St bases that view on detailed assumptions for future revenue expansion, margins and risk through its chosen discount rate of 9.06%.

The hardware road map from Helios to Sol in 2027 and Apollo in 2029 is being derisked through intermediate milestones such as validated 2D QCCD trap chips and new error correction code families. This can help sustain premium system pricing and support long run gross margin targets above 50%.

Result: Fair Value of $83.00 (UNDERVALUED)

Still, the heavy quarterly net loss, alongside potential delays to the Sol and Apollo hardware targets, could quickly challenge any bullish Quantinuum valuation story.

Another Take: Multiples Paint A Tougher Picture

On a cash flow model, Quantinuum screens as attractive, with the share price of $40.57 trading 76.1% below an estimate of $170.10. A simple P/B check tells a different story. QNT changes hands at 4.1x book value while US IT peers average around 2x and direct peers sit near 2.3x. That gap points to meaningful valuation risk if sentiment cools.
