According to filings with the U.S. Securities and Exchange Commission, Antares Nuclear is raising up to $470 Million in new funding. The federal securities law requires the notice to be filed by companies that have sold securities without registration under the Securities Act of 1933 in an offering made under Rule 504 or 506 of Regulation D or Section 4(a)(5) of the Securities Act. A company must file this notice within 15 days after the first sale of securities in the offering. For this purpose, the date of first sale is the date on which the first investor is irrevocably contractually committed to invest. Each issuer of securities that sells its securities in reliance on an exemption provided in Regulation D or Section 4(a)(5) of the Securities Act of 1933 must file this notice containing the information requested with the U.S. Securities and Exchange Commission (SEC) and with the state(s) requiring it. If more than one issuer has sold its securities in the same transaction, all issuers should be identified in this filing with the SEC.

About Antares Nuclear
Energy abundance unlocks progress. It powers missions, grows economies, strengthens national security, and expands whats possible on Earth and beyond. But in the places where power is most critical, its often the hardest to deliver. Thats the problem were solving. At Antares, were building compact nuclear microreactors to deliver reliable, mobile energy where its needed most: remote military bases, austere industrial sites, and, one day, deep space and underwater missions. The U.S. nuclear industry hasnt seen true momentum in decades. Were moving it forward with urgency, humility, and a commitment to building whats needed now. Our team includes engineers and operators from SpaceX, Relativity Space, Ursa Major, the White House, MIT, Rigetti Computing, and the U.S. Air Force. Backed by over $600M from top-tier investors, were focused on shipping hardware, not hypotheticals. In 2025, we set the pace for advanced reactor development completing our Conceptual Design Review (CDR) on an accelerated timeline and becoming the first company in the country to receive an approved Nuclear Safety Design Agreement (NSDA) for a reactor. We opened Antares Prime322,000 sq-ft of vertically integrated R&D spaceto accelerate in-house manufacturing and iteration, tested our first Electrically Heated Demonstration Unit (EDU), submitted our Preliminary Documented Safety Analysis (PDSA), prepared our reactor test site, and became the first U.S. microreactor to receive a HALEU allocation and begin fuel fabrication. In 2026, we conducted our first reactor demonstration at Idaho National Laboratory under the Department of Energys Reactor Pilot Program validating reactor physics, reactivity control behavior, and system-level safety performance in operation. In parallel, we will close the final reactor design and safety analysis and complete qualification of our heat pipes, heat exchanger, and power conversion system, setting the conditions to produce electricity in 2027. In 2027, we operate a full-power, electricity-producing advanced reactor on American soil.
