Quantum Leap Energy LLC Announces Private Placement of Convertible Notes Led by American Ventures LLC

WASHINGTON, Nov. 07, 2025 (GLOBE NEWSWIRE) — Quantum Leap Energy LLC (“QLE”), a wholly-owned subsidiary of ASP Isotopes Inc. NASDAQ: ASPI (“ASP Isotopes” or “ASPI” or the “Company”), an advanced materials company focused on developing technologies and processes for the production of isotopes for multiple industries, today announced that QLE has commenced an offering of QLE’s convertible notes in a private placement to accredited investors and certain non-U.S. persons. QLE has entered into a definitive convertible note purchase agreement with certain investors for an initial closing of US$64.3 million aggregate principal amount of QLE’s convertible notes (the “Notes”).

The issuance of Notes pursuant to the offering will result in the automatic conversion of QLE’s outstanding convertible promissory notes originally issued in March 2024 and June 2024 (together, the “2024 Convertible Notes”), pursuant to their terms.

The Notes will be unsecured and may be convertible into common equity securities of QLE, prior to maturity, and upon the occurrence of certain events, including an initial public offering, direct listing or a future equity financing, in each case at a price per share equal to the lower of 80% of the per share price in the applicable transaction or the per share value of one share of QLE’s common equity based on a set valuation cap.

The Notes will mature on the fifth anniversary of the initial closing, unless converted in accordance with their terms prior to such date. QLE may not repay the Notes prior to maturity, unless a change of control transaction occurs.

QLE intends to use the net proceeds from the offering to build and develop laser enrichment production facilities, as well as for general corporate purposes. Neither QLE nor the Company will receive any proceeds from the automatic conversion of the 2024 Convertible Notes into Notes.  

The offering was led by ASPI and American Ventures LLC, with capital contributions from both Eric Trump and Donald Trump Jr.   The initial closing of the offering is expected to be on or about November 10, 2025, subject to satisfaction of customary closing conditions.

The Notes are being offered to institutional investors that qualify as “accredited investors” (within the meaning of Rule 501(a) of the United States Securities Act of 1933, as amended (the “Securities Act”)) or investors that are not a person in the United States or a U.S. Person (within the meaning of Rule 902(k) of Regulation S promulgated under the Securities Act). The Notes and the common equity securities of QLE deliverable upon conversion of the Notes (if any) have not been and will not be registered under the Securities Act or any other applicable securities laws, and may not be sold or otherwise transferred in the United States except under an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and in compliance with any other applicable securities laws.

QLE may issue additional Notes in subsequent closings to investors who are non-U.S. persons in transactions outside of the United States in reliance on Regulation S under the Securities Act.

Canaccord Genuity acted as placement agent in the United States and Ocean Wall Limited acted as placement agent outside the United States.

This press release shall not constitute an offer to sell or a solicitation of an offer to purchase any securities, nor shall there be a sale of the securities in any state or jurisdiction in which such an offer, solicitation or sale would be unlawful.

About ASP Isotopes Inc.

ASP Isotopes Inc. is a development stage advanced materials company dedicated to the development of technology and processes to produce isotopes for use in multiple industries. The Company employs proprietary technology, the Aerodynamic Separation Process (“ASP technology”). The Company’s initial focus is on producing and commercializing highly enriched isotopes for the healthcare and technology industries. The Company also plans to enrich isotopes for the nuclear energy sector using Quantum Enrichment technology that the Company is developing. The Company has isotope enrichment facilities in Pretoria, South Africa, dedicated to the enrichment of isotopes of elements with a low atomic mass (light isotopes).

There is a growing demand for isotopes such as Silicon-28, which will enable quantum computing, and Molybdenum-100, Molybdenum-98, Zinc-68, Ytterbium-176, and Nickel-64 for new, emerging healthcare applications, as well as Chlorine-37, Lithium-6, and Uranium-235 for green energy applications. We believe the ASP technology (Aerodynamic Separation Process) is ideal for enriching low and heavy atomic mass molecules. For more information, please visit www.aspisotopes.com.
