Mizuho Trims Price Targets for Quantum Computing Leaders, Maintains Bullish Outlook

Mizuho slashes price targets for D-Wave, IonQ, and Rigetti but maintains long-term optimism. D-Wave's revenue surged 179%, yet valuation remains a key challenge.

A sweeping reassessment of the quantum computing sector by Mizuho Securities has led to significant price target reductions for several key players, applying downward pressure across the industry. Shares of D-Wave Quantum, IonQ, and Rigetti Computing each declined approximately 4% on Tuesday following the analyst's report. Despite the cuts, the firm's underlying optimism regarding the sector's long-term prospects creates a notable market dynamic.

Valuation Reset Amidst Sustained Conviction

Mizuho analyst Vijay Rakesh maintained his "Outperform" rating on D-Wave Quantum while lowering his price target from $40 to $31 per share. He applied similar adjustments to peers Rigetti Computing, reducing its target from $43 to $33, and IonQ, cutting its target from $80 to $61. This comprehensive review was prompted by an updated sector evaluation following the recent Nvidia GTC conference and other industry developments.

Even with the reduced target, Mizuho's new projection for D-Wave implies an upside potential of over 100% from its current trading level near $14. The analysis highlights D-Wave's dual-strategy approach, which involves pursuing both annealing and gate-model superconducting quantum systems. Mizuho views this diversified technological roadmap as a potential competitive advantage. The firm's projections suggest D-Wave could capture roughly 10% of the quantum computing market by 2030.

Strong Growth Metrics Contrast with Widening Losses

The financial picture for D-Wave's fiscal year 2025 presents a mixed narrative. Revenue surged 179% to $24.6 million, supported by a robust gross margin of 82.6%. However, the company's adjusted EBITDA losses expanded to $71.8 million. A positive signal comes from bookings, which reached $32.8 million in the first two months of fiscal 2026, indicating sustained customer demand.

A closer look at the revenue composition reveals a significant detail: recurring revenue from Quantum Computing as a Service (QCaaS) subscriptions contributed only $5.5 million. The majority, $16.2 million, came from system sales. This breakdown represents a relevant consideration for investors focused on scalable, high-margin software revenue streams.

Lofty Valuation Presents a Persistent Challenge

D-Wave shares currently trade around $14.14, a level roughly 70% below their 52-week high of $46.75. The company's market capitalization stands at $5.23 billion, which represents a multiple of 215 times its last annual revenue of $24.6 million.

The critical question for investors is whether the combination of substantial global investment tailwinds and commercial momentum can justify this valuation gap. The United Kingdom has announced plans to invest approximately $2.7 billion in quantum technologies over the next four years, while Canada is committing an additional $1 billion for defense-related quantum programs. On the technological front, Mizuho notes the race to achieve more than 200 logical qubits is expected to reach a decisive phase between 2027 and 2029. Until then, D-Wave remains a stock where the compelling growth narrative and valuation realities appear significantly disconnected.
