Deep Fission’s Second Bite at the Public Market

Deep Fission, a nuclear startup, has announced its intention to go public on Nasdaq, seeking $157 million in funding. This move comes just six months after the company went public via a reverse merger, raising $30 million in a private placement. However, the previous public listing was in name only, as the company’s stock never actually traded. This raises questions about the company’s decision to pursue a traditional IPO route, especially considering its worsening financial position.

Deep Fission’s financial situation has deteriorated since its previous public listing. As of March, its deficit had grown to $88.1 million from $56.2 million, and its cash and cash equivalents declined by $6.4 million in the last month and a half. The company’s S-1 filing also contains a “going concern” warning, indicating that it may run out of money in the next 12 months if the IPO is not successful.

The company’s technical progress has also been slow. Deep Fission has started drilling a test well, but the challenges in moving from a test well to commercial scale are likely to be significant. The company needs to drill boreholes 30 to 50 inches in diameter and a mile deep, which is a complex and costly process.

Drilling into Deep Fission’s Decision Logic

Deep Fission’s decision to pursue a traditional IPO route is puzzling, especially given its worsening financial position. The company’s S-1 filing does not provide a clear explanation for the decision, and the company declined to comment, citing the quiet period before its IPO. However, it is possible that the company and its backers are seeking to capitalize on investor excitement over fission power.

Deep Fission’s financial situation suggests that it needs the funding from the IPO to stay afloat. The company’s cash burn rate is high, and its deficit has grown significantly since its previous public listing. The IPO proceeds will likely be used to fund the company’s drilling operations and reactor design.

The company’s technical progress also suggests that it is still in the early stages of development. Deep Fission has not yet finalized its reactor design, and the challenges in moving from a test well to commercial scale are significant. The company’s decision to prioritize drilling may be a tacit admission that making holes in the ground is not as easy as it sounds.

Winners and Losers in Deep Fission’s IPO

Deep Fission’s IPO is likely to benefit the company’s investors and backers, who will see a significant return on their investment if the IPO is successful. The company’s employees may also benefit from the IPO, as they may receive stock options or other equity incentives.

However, the IPO may not benefit the company’s customers or the broader nuclear energy industry. Deep Fission’s technology is still in the early stages of development, and it is unclear whether the company will be able to deliver on its promises. The IPO may also create unrealistic expectations about the company’s prospects, which could lead to a correction in the stock price if the company fails to deliver.

The IPO may also have implications for the nuclear energy industry as a whole. If Deep Fission is successful, it could create a new model for nuclear energy companies to go public and raise capital. However, if the company fails, it could create a negative perception of the industry and make it harder for other companies to raise capital.

The Skeptical Case

Deep Fission’s IPO is not without its risks. The company’s financial situation is precarious, and its technical progress has been slow. The company’s decision to pursue a traditional IPO route may be a sign of desperation, and the IPO may not be successful.

Additionally, the company’s technology is still in the early stages of development, and it is unclear whether the company will be able to deliver on its promises. The IPO may create unrealistic expectations about the company’s prospects, which could lead to a correction in the stock price if the company fails to deliver.

What to Watch Next

Deep Fission’s IPO is expected to close in the coming weeks. Investors should watch for the company’s quarterly earnings report, which will provide more information about the company’s financial situation and technical progress.

Additionally, investors should watch for any updates on the company’s reactor design and drilling operations. The company’s ability to deliver on its promises will be critical to its success, and any setbacks or delays could have a negative impact on the stock price.
