Oklo posted a Q1 net loss of $33.1 million, compared with a $17.9 million loss in the same quarter last year. The widened loss reflected both higher operating costs and accelerated investments in research and infrastructure.

Spending on the Aurora advanced reactor program and related site development rose substantially, driving much of the cost increase. Management emphasized that these expenditures support engineering milestones, licensing efforts and facility buildouts.

Shares fell by about 6% as investors digested the heavier-than-expected loss and elevated cash burn. While the investment bolsters long-term growth prospects, the company faces near-term funding pressures until commercialization milestones are achieved.
