Oklo's loss widened in the third quarter as the company spent more on research and development to advance its plans to launch a commercial nuclear energy plant.

The nuclear energy company on Tuesday posted a loss of $29.7 million, or 20 cents a share, compared with a loss of $10.0 million, or 8 cents a share, a year earlier. Analysts polled by FactSet expected a loss of 13 cents a share.

Oklo has not yet recorded any sales, as the company is still waiting to get its nuclear-reactor plans approved by regulators.

The loss was primarily driven by payroll and general business expenses, as well as a non-cash stock-based compensation expense of $9.1 million, Oklo said. Research and development expenses increased to $14.9 million from $5.1 million the year before.

The company in July completed the Nuclear Regulatory Commission's pre-application readiness assessment for the first phase of its combined license application for a commercial nuclear plant.

In August, Oklo was selected by the Energy Department for three reactor pilot program licenses, which are designed to fast-track commercial nuclear reactor licenses and testing.
