Analysis · OKLO · Energy & Transportation
Oklo's Q2 results show a net loss of $48.5 million, up from $24.7 million a year ago, as R&D and G&A spending more than doubled to support its reactor and fuel programs. The company raised $1.85 billion through its ATM programs in the first half of 2026, including $670 million in Q2, ending the quarter with $3.0 billion in cash and marketable securities. Two acquisitions closed in June add precision manufacturing and chemical process engineering capabilities. The Groves Isotope Test Reactor achieved first criticality on August 5, 2026, a major technical milestone that validates the company's reactor design and operational readiness. The cash position provides a multi-year runway, but the accelerating cash burn and ongoing dilution from the ATM program are key investor concerns.
