Key Terms

convertible promissory notes, aggregate principal amount, record date

3 terms

convertible promissory notes financial

"private exchange agreements ... with certain holders of QLE’s outstanding convertible promissory notes"

A convertible promissory note is a loan a company takes that can later be turned into shares instead of being paid back in cash; think of lending money now in exchange for a voucher that can become ownership later. Investors care because it mixes credit risk and potential ownership upside—it can protect lenders if a company struggles while also diluting existing shareholders when converted, affecting future share value and investor returns.

aggregate principal amount financial

"exchange approximately $109.2 million in aggregate principal amount of outstanding QLE Notes"

The aggregate principal amount is the total amount of money borrowed through a bond or loan that the borrower promises to repay. It’s like the original price tag on a loan or bond, showing how much money is involved in the deal. This number matters because it indicates the size of the debt and helps investors understand the scale of the borrowing.

record date financial

"future distribution of its QLE common equity to ASPI’s stockholders as of a to-be-determined future record date"

The record date is the specific day when a company determines which shareholders are eligible to receive a dividend or participate in an upcoming vote. It’s like a cutoff date; if you own the stock on that day, you get the benefits or voting rights. This date matters because it decides who qualifies for certain company benefits.

Exchange reduces QLE’s outstanding convertible notes by approximately 50% as QLE continues to pursue a public listing as a separate company

DALLAS, July 15, 2026 (GLOBE NEWSWIRE) -- ASP Isotopes Inc. (NASDAQ: ASPI) ("ASPI", the "Company" or “we”) today announced that ASPI and Quantum Leap Energy LLC ("QLE"), a wholly-owned subsidiary of ASPI dedicated to advancing innovative technologies and processes across critical segments of the fission and fusion nuclear fuel cycle, have entered into separate, individually negotiated private exchange agreements (the “Exchange Agreements”) with certain holders of QLE’s outstanding convertible promissory notes (the “QLE Notes”).

Under the terms of the Exchange Agreements, certain holders of QLE Notes have agreed to exchange approximately $109.2 million in aggregate principal amount of outstanding QLE Notes held by them, plus accrued and unpaid interest thereon, for an aggregate of approximately 23.2 million shares of ASPI common stock, representing approximately 17.8% of ASPI’s common stock outstanding (collectively, the “Exchange Transactions”).

The Exchange Transactions are intended to reduce QLE’s outstanding convertible notes by approximately 50% and simplify QLE’s capital structure as QLE continues to pursue a public listing on a U.S. national securities exchange as a standalone company.  The Exchange Transactions are also expected to support ASPI’s position to make a potential future distribution of its QLE common equity to ASPI’s stockholders as of a to-be-determined future record date.

The Exchange Transactions are expected to close on July 16, 2026, subject to satisfaction of customary closing conditions.  Upon closing of the Exchange Transactions, the outstanding principal amount of QLE Notes will be reduced by approximately 50%, from $219.8 million to $110.7 million in aggregate principal amount outstanding.

“The exchange significantly strengthens QLE’s balance sheet, reducing its convertible notes by approximately 50% and simplifying its capital structure at the right moment as QLE continues its path towards a separate public listing,” said Paul Mann, Chairman and Chief Executive Officer of ASPI.  “QLE is making significant progress in executing its business plan. We structured the exchange to be broadly economically neutral to both ASPI stockholders and QLE noteholders, and we look forward to supporting QLE moving forward.”
