Deep Fission (FISN) is drawing attention after signing non binding Letters of Intent tied to as much as 18.5 GW of potential nuclear capacity, along with progress on its first underground reactor project in Kansas.

Despite the new LOIs and recent index inclusion, Deep Fission’s 1 day share price return declined 21.54% and its year to date share price return is down 32.97%, suggesting momentum has cooled quickly after the IPO.

With Deep Fission now trading well below its US$16 IPO price despite fresh LOIs tied to 18.5 GW of potential capacity, investors face a key question: is this weakness a reset that opens an opportunity, or is the market already discounting future growth?

Preferred Price-to-Book Multiple of 10x: Is It Justified?

With Deep Fission last closing at $9.76 and still pre revenue and loss making, the clearest yardstick investors have today is its price-to-book ratio relative to peers.

The preferred multiple here is P/B, which compares Deep Fission’s market value to its book value, or net assets on the balance sheet. For early stage, asset heavy businesses, this can help you see how much the market is paying over stated equity for the company’s reactor technology, development pipeline and future project potential.

On a peer comparison, Deep Fission’s P/B of 10x is described as good value against a peer average of 23.6x. This suggests the stock is priced below some similar companies that are also being valued heavily on future potential. However, against the broader US Construction industry average P/B of 3.9x, the same 10x multiple is described as expensive. This indicates the market is assigning a much richer valuation than more traditional construction related businesses.

This split view means the P/B looks more restrained when you frame Deep Fission against close peers, but elevated when you widen the lens to the sector level.

Result: Price-to-book of 10x (ABOUT RIGHT)

However, Deep Fission’s pre revenue status and reported net loss of $79.21 million mean that funding needs and execution on long dated reactor projects remain key pressure points.
