Other ventures backed by the Trump family span drones, blank-check companies and Bitcoin mining.QLE enriches isotopes primarily for use in nuclear energy production, according to company filings. Its technology can enrich isotopes at a fraction of the cost of traditional facilities, according to its website. The company intends to use the proceeds from the offering to “build and develop laser enrichment production facilities,” it said.A company majority owned by Dominari was named manager of American Ventures, according to a securities filing.The offering is expected to close Nov. 10, pending normal closing conditions. Canaccord Genuity Group Inc. has arranged the placement in the US, and Ocean Wall Ltd. served in that role for the foreign transaction. The issuance of the convertible notes will trigger the automatic conversion of promissory notes issued in March and June of 2024, the statement said. ASP Isotopes said in September, before the US government shutdown, that it was targeting a public listing for the unit in the fourth-quarter. The convertible notes would convert into stock if the company goes public or under certain other events, the Friday statement said. ASP aims to take QLE public through a direct listing, though the timing is not firm because of the government shutdown. The listing could value the firm higher than the convertible note, the person said..© 2025 Bloomberg L.P.
