BERKELEY, CALIF. -- Deep Fission, Inc. (“Deep Fission” or the “Company”), a pioneering advanced nuclear energy company placing small modular pressurized water reactors in boreholes one mile underground, announced it raised $30M in a heavily oversubscribed private placement offering at $3.00 per share as well as completed a go-public reverse merger transaction with Surfside Acquisition Inc., which has been renamed Deep Fission, Inc.

The Department of Energy (DOE) recently announced that Deep Fission was selected to participate in President Trump’s Nuclear Reactor Pilot Program. The initiative provides an opportunity to streamline a pilot reactor, targeting criticality by July 4, 2026, with expected rapid commercialization to follow.

“This is a unique moment for the nuclear industry,” said Liz Muller, Co-Founder and Chief Executive Officer of Deep Fission. “Deep Fission has the right technology, at the right time, and in the right place. With this funding, we can begin building our pilot reactor, with the goal of completion in 2026. We believe we can scale our technology rapidly and profitably to address the massive energy demand from AI data centers and other customers around the world.”

Deep Fission’s proprietary design combines proven methods from the nuclear, oil and gas, and geothermal industries, while utilizing off-the-shelf parts and readily available, low-enriched uranium (LEU) to simplify supply chains. By siting the reactor one mile underground, the surrounding geology offers natural shielding and protection with billions of tons of bedrock providing passive safety and containment. The approach reduces the surface footprint, strengthens security, and is designed to enable a faster, more affordable path to deployment. The Company is targeting a levelized cost of electricity (LCOE) of 5-7 cents per kWh from its first-of-a-kind commercial implementation.

Backed by a robust intellectual property portfolio, the Company currently has 24 pending patent applications with 1 US application allowed and over 40 unique innovations.

As a result of the reverse merger, the Company is now subject to the public reporting requirements of the Securities Exchange Act of 1934, as amended. The Company intends to file a resale registration statement on Form S-1 with the SEC to register its outstanding shares and will apply to have its shares approved for quotation on the OTCQB (The Venture Market).

The Benchmark Company, LLC, Seaport Global Securities LLC, Network 1 Financial Securities, Inc., Phoenix Financial Services, and Dinosaur Financial Group, LLC served as placement agents. Montrose Capital Partners sponsored the go-public transaction, and investors in Deep Fission include 8VC, Deep Future, Wave Function, Ed Eisler of EE Holdings, and Mark Tompkins of Montrose Capital Partners.
