Uncertainty of Technological Breakthroughs and Commercialization Success: Rigetti's ability to develop commercially viable, fault-tolerant quantum computers depends on overcoming complex scientific and engineering challenges, which may not be achieved as expected or on projected timelines.

Intense and Evolving Competitive Landscape: Rigetti faces significant competition from well-capitalized technology companies, academic institutions, and other startups, some of whom may achieve breakthroughs or market adoption ahead of Rigetti.

Limited Market Adoption and Customer Demand: The market for quantum computing solutions is still emerging, and there is no guarantee that enterprises or governments will adopt Rigetti's offerings at scale, impacting revenue growth and profitability.
