Oklo (OKLO) concentration risks

The company's concentration profile at this stage of development is defined entirely by supply-side dependencies, both of which carry a high disclosed size. The first and most fundamental is fuel: HALEU — the enriched uranium required to power the company's microreactors — is available only in limited quantities globally, making this a high-share dependency with no readily substitutable alternative. The second layer is component-level: certain parts and subsystems are designed exclusively for the company's powerhouses, fuel fabrication and recycling facilities, and radioisotopes operations, meaning sole-source supplier relationships are embedded across multiple facility types rather than isolated to a single production line. Both exposures are structural in character — they reflect the early-stage, proprietary nature of the technology rather than avoidable procurement choices. The HALEU constraint in particular is an industry-wide bottleneck, not a company-specific negotiating failure, and resolution depends on enrichment capacity being developed across the broader nuclear supply chain. The component dependency similarly flows from the bespoke design of the powerhouses, which limits the ability to qualify alternative vendors without significant redesign risk. Taken together, these two high-share supply dependencies are the central concentration risk for investors to track: both could delay commercialization timelines if supply chains are slow to develop, and neither is quickly resolved through conventional procurement diversification.
