As a century-old industrial giant, the independent listing of Honeywell’s quantum business will have the following effects:

1. Increased Recognition from Institutional Investors
   • Endorsement by traditional blue-chip companies reduces perceived investment risks
   • Attracts conservative institutional capital that was previously on the sidelines
   • Establishes a valuation reference benchmark for the industry

2. Rationalization of Valuation Multiples
   • Quantinuum’s $10 billion valuation provides a pricing benchmark for the industry
   • Helps correct valuation deviations caused by pure concept speculation
   • Guides the market to focus on fundamentals and commercialization progress

3. Surge in Capital Market Attention
   • Quantum computing becomes a hot investment theme on Wall Street
   • Drives the overall industry valuation level upward
   • Increases analyst coverage and research reports

The demonstration effect of Honeywell’s IPO will drive:

The over $1.5 billion IPO of Honeywell’s quantum computing subsidiary Quantinuum is a milestone event in the history of the quantum computing industry. This event reflects:

1. Paradigm Shift in Capital Markets
   : The process of quantum computing moving from the laboratory to the capital market is accelerating
2. Strategic Adjustment of Traditional Giants
   : Independent financing for cutting-edge technology businesses has become a new trend
3. Increasing Differentiation in Industry Valuation
   : While leading companies receive high valuations, bubble risks are also accumulating

:

• The quantum computing industry is at a critical juncture of technological breakthroughs and commercialization transformation
• The period 2026-2030 will determine which technological routes and business models will succeed
• Short-term valuation risks need to be vigilant, but long-term investment value cannot be ignored

, quantum computing is expected to take the lead in large-scale applications in fields such as financial optimization, drug R&D, and AI integration, creating significant returns for investors. However, given that current valuation levels significantly deviate from fundamentals, it is recommended that investors remain cautious and wait for a more reasonable entry point.
