One information headline this week had a whiff of déjà vu about it. Nuclear startup Deep Fission introduced that it was going public, hoping to garner investor help to construct subterranean reactors to energy AI knowledge facilities.
Wait, didn’t I already write that story? I might have sworn that I did.
Oh proper, I did. Final September, Deep Fission mentioned that it had gone public by way of a reverse merger with Surfside Acquisition, a Delaware shell firm, a transaction through which a non-public firm acquires an present publicly listed entity to realize a inventory market itemizing — elevating $30 million in a concurrent personal placement at $3 a share. Now it’s searching for $157 million in a Nasdaq IPO at $24 to $26 a share. You possibly can see my confusion.
Seems the earlier public itemizing was public in title solely. The reverse merger with Surfside was accomplished, making Deep Fission a reporting firm with SEC obligations, however its inventory by no means really traded. The corporate had mentioned it supposed to checklist on the OTCQB, a market for creating corporations that don’t meet the itemizing necessities of main exchanges just like the NYSE or Nasdaq. However searches for Deep Fission on OTCQB don’t return any outcomes, and the corporate, in its S-1, denied that its inventory had ever been publicly traded.
In response to questions from TechCrunch, Deep Fission declined to remark, citing the quiet interval earlier than its IPO.
Deep Fission’s new public providing on Nasdaq is following the extra conventional IPO route, with an providing that will worth the corporate at as much as $1.66 billion. It’s a large determine for a corporation that one 12 months in the past was struggling to boost a $15 million funding spherical.
Stranger nonetheless, the image painted within the S-1 filed on May 20 is arguably bleaker than the one outlined within the December filing with the SEC. Its timeline for turning on its first reactor has slipped. Additional, again in December, it had hoped to realize criticality — the purpose at which a nuclear chain response turns into self-sustaining — by July 2026. Now, it gained’t present an estimate.
Deep Fission does level out that it’s drilling a take a look at properly. It has additionally misplaced some huge cash.
One factor that hasn’t modified: The brand new S-1 assertion comprises the identical “going concern” warning current in December. If Deep Fission doesn’t full the IPO, it might run out of cash within the subsequent 12 months.
The truth is, the startup’s monetary place has worsened in current months. As of March, its deficit had grown to $88.1 million from $56.2 million. Within the final month and a half, the corporate’s money and money equivalents declined by $6.4 million, or about 7%.
On the technical entrance, Deep Fission says it’s now prioritizing drilling, maybe a tacit admission that making holes within the floor isn’t as straightforward because it sounds.
The corporate says it began drilling the primary of three take a look at wells in March. The properly will probably be used to gather knowledge “as much as 6,000 ft deep.” At eight inches in diameter, it’s fairly a bit smaller than will probably be wanted at business scale.
The challenges in shifting from a take a look at properly to business scale are prone to be vital. Deep Fission says it should want boreholes 30 to 50 inches in diameter and a mile deep, although it hasn’t settled on a particular dimension but. Even on the low finish, its boreholes will probably be bigger than what’s sometimes used in the oil and gas industry. And till Deep Fission is aware of how massive of a gap it could actually drill, it’ll have a tough time finalizing its reactor design.
So what has modified since December that will spur an even bigger providing at a nine-figure valuation? The corporate did obtain an $80 million fairness funding, together with $20 million from knowledge heart developer Blue Owl, which additionally signed a non-binding MOU for future energy vegetation. Nonetheless, that wasn’t sufficient to stave off the going concern warning. It’s doable that Deep Fission is sitting on some constructive data that it omitted from the S-1, although that’s arduous to imagine given what’s driving on the IPO.
It’s extra doubtless that the corporate and its backers are searching for to capitalize on investor pleasure over fission energy. Simply final month, nuclear fission startup X-energy went public in an upsized IPO. However in contrast to Deep Fission, X-energy is producing income and is significantly farther along within the Nuclear Regulatory Fee’s licensing course of — a distinction that serves as a helpful reminder that in a sector the place enthusiasm can run properly forward of technical and regulatory actuality, valuation and progress aren’t the identical factor.
It isn’t precisely clear what components are driving Deep Fission towards its IPO, however technological or business progress doesn’t appear to be amongst them.
