Oklo
What matters nowUpdated 7 h ago
- Oklo's latest company filing in our records is an 8-K dated Sep 10, 2026 and filed Sep 11, reporting both entry into and termination of a material definitive agreement 1. Earlier, the company reported a director or officer change in an 8-K filed Jul 28 2 and its Q2 2026 10-Q on Aug 7 3.
- OKLO traded at a pooled 24/7 venue price of $31.76 on Oct 13, down 1.03% from $32.09. Recent daily moves were +7.71% on Oct 6, -5.11% on Oct 7, -6.46% on Oct 8 and -7.97% on Oct 12.
- Oklo has no revenue in our data. For the year to Dec 31, 2025 it reported a net loss of $105.7M, EPS of -$0.72 and free cash flow of -$115.4M. The balance sheet shows net cash of $788.4M against a $5.10B market cap. Over the last 180 days insiders sold 2.12M shares worth $115.1M in 34 sales (24 of them planned) and bought none.
- The first Aurora powerhouse unit cleared a DOE preliminary documented safety analysis at Idaho National Laboratory on Jun 11, 2026, with deployment targeted for 2028. The Groves isotope test reactor in Texas reached first criticality in August 2026. A January 2026 agreement with Meta covers up to 1.2 GW of nuclear power from the Pike County, Ohio campus.
- Next, the Q3 2026 results call is estimated for Oct 28 and the Q3 results for Nov 10, both unconfirmed. The Q3 10-Q is due Nov 16, 2026.
Oklo is a pre-revenue advanced nuclear company developing small fast-fission power plants called Aurora powerhouses, which it plans to own and operate to sell electricity and heat. It is also building fuel recycling and fabrication capacity in Tennessee and Idaho, and runs a radioisotope business through Atomic Alchemy and its Groves test reactor in Texas. The company has no NRC approvals for its powerhouses yet and is advancing its first unit through the Department of Energy's authorization path.
How it makes money
Oklo plans to build, own and operate Aurora powerhouses and sell the power and heat, mainly under long-term power purchase agreements, such as the 1.2 GW Pike County, Ohio campus agreement with Meta announced in January 2026. Until then revenue is minimal: Oklo reported $1.2 million of revenue in the quarter ended June 30, 2026, after none in the same quarter of 2025, and attributed it mainly to businesses acquired in 2026. Its radioisotope business sells isotopes, and its fuel recycling and fabrication plans are intended to supply its own reactors.
