Oklo Widens Aurora Startup Window to 2028–2029, Adding Schedule Risk

What happened

Oklo used its Q3 2026 earnings call to disclose that the first Aurora powerhouse in Idaho may now come online in 2028 or 2029, softening the previous 2028-only target. The new guidance adds commissioning and startup time to the DOE-track project, consistent with filings that already showed pre-application NRC activity and no definitive fuel contract. Oklo's balance sheet remains liquid at $3.0 billion, but the company generated only $1.2 million of revenue in 1H26 and has yet to convert major customer agreements into binding PPAs. The master report's base scenario (45% probability) values shares at $43, roughly in line with the last price of $42.60, while the bear case (30%) drops to $32. This news does not break the thesis but reinforces that commercialization remains a 2028–2029 event rather than a near-term certainty.

Implication

Investors should treat the 2028–2029 range as the new base timeline for first Aurora revenue, meaning the 2028 milestone checkpoints in the master report become less rigid. The next six to twelve months hinge on converting the Meta-linked Ohio prepayment framework into a binding PPA and signing a definitive HALEU contract with Centrus. Without those contracts, Oklo's $3.0 billion cash pile will continue to fund pre-revenue development, diluting shareholders further. The WAIT rating remains appropriate: current price $42.60 sits near the base-case fair value of $43, leaving little margin of safety for execution slippage. We would reduce exposure if no new DOE authorization step or contract conversion appears by 1H27, and would add only on a pullback toward the $34 attractive-entry level or evidence of a definitive commercial agreement.

Thesis delta

The previous thesis already priced a 2028 commercialization target with visible slippage risk; the new 2028–2029 window shifts the probability weight slightly toward the bear scenario. This lowers the expected value from roughly $43 to $42–43, keeping the stock within the WAIT range. A definitive PPA or fuel contract before 1H27 remains the primary catalyst that could justify upgrading the call.
