A company that has rapidly ascended in the market, Oklo, focuses on developing next-generation nuclear reactors and has stunned investors by increasing its stock price over 1,600% in just one year. Despite this remarkable growth, the firm has yet to generate revenue, raising questions about its long-term viability.
The surge in Oklo’s market value coincided with a renewed appreciation for nuclear energy, largely influenced by the policies of former President Donald Trump. An executive order issued in May, titled “Deploying Advanced Nuclear Reactor Technologies for National Security,” emphasized the need for reliable energy sources for critical infrastructure. This government endorsement has positioned Oklo favorably, as it specializes in advanced reactor technologies that align with national security objectives.
In addition to Trump’s directive, the passing of a significant energy bill in July provided further momentum for the nuclear sector, benefiting Oklo and its peers. This wave of support has not only lifted Oklo but also propelled other companies in the nuclear space, such as small modular reactor developer NuScale Power, which saw an increase of 89% in its stock during the same timeframe, while uranium producer Cameco witnessed a staggering 282% rise. In contrast, the S&P 500 index experienced a modest 16% increase over the same period.
The U.S. government and Oklo are swiftly advancing initiatives; in mid-August, the Department of Energy (DOE) selected Oklo and its Atomic Alchemy subsidiary to develop three pilot reactor projects, aiming for full operational capability by July 4, 2026. Shortly after, Oklo announced a partnership with engineering firm ABB to establish a digital monitoring room at its California headquarters, facilitating ongoing projects. Furthermore, the company is collaborating with Swedish nuclear developer Blykalla to enhance their production processes and share insights on best practices.
To bolster its financial position during this period of rapid development, Oklo initiated a secondary common stock offering in June, expected to yield over $540 million. However, despite these promising developments, concerns linger regarding its financial health. In the first half of the year, Oklo incurred total operating expenses nearing $46 million, leading to a considerable loss of $34 million. With annual cash burn approaching $53 million and a growing workload, questions about its cash runway and sustainability arise.
Additionally, regulatory approval for Oklo’s Aurora reactor design is still pending, casting further uncertainty over its financial future. Despite boasting a significant market capitalization of approximately $16.5 billion and a high price/book ratio of over 23, some analysts view Oklo as overpriced compared to revenue-generating peers like NuScale, which has a market cap slightly above $5 billion and a price/book ratio close to 7.
Given the company’s current standing and the challenges that lie ahead, cautious investors may prefer to adopt a wait-and-see approach regarding Oklo’s potential for sustainable growth. While the nuclear energy sector experiences newfound attention, the viability of pre-revenue companies like Oklo remains uncertain.
