Mirion Technologies, Inc. furnished an update that it issued a press release announcing financial results for the fiscal quarter ended September 30, 2025. The press release is provided as Exhibit 99.1.
The information in Items 2.02 and 9.01, including Exhibit 99.1, is being furnished and is not deemed “filed” under Section 18 of the Exchange Act, nor incorporated by reference in other filings unless expressly stated.
Mirion Technologies completed two major financing transactions to support a planned acquisition and general corporate needs. The company sold 19,906,322 shares of Class A common stock at $21.35 per share in a public offering, generating approximately $409.7 million in net proceeds. It also issued $375.0 million of 0.00% Convertible Senior Notes due 2031 in a private offering, with net proceeds of about $365.2 million.
The notes are unsecured, mature on October 1, 2031, and are initially convertible at 34.6951 shares per $1,000 principal amount, implying a conversion price of about $28.82 per share, a 35% premium to the stock offering price. Mirion entered into capped call transactions, capped at $42.70 per share, to reduce potential dilution or offset cash payments on conversion. The company expects to use about $38.0 million for the capped calls and apply the remaining proceeds from both offerings primarily to fund the planned Paragon Energy Solutions acquisition and for general corporate purposes.
Mirion Technologies, Inc. disclosed that it has signed an Equity Purchase Agreement to acquire all of the issued and outstanding equity interests of Paragon Energy Solutions for $585 million in an all‑cash transaction. The purchase price is subject to working capital and other customary adjustments.
To backstop the acquisition financing, Mirion obtained $585 million in incremental term loan commitments from Goldman Sachs Lending Partners LLC, with funding subject to conditions in a debt commitment letter. Closing depends on customary conditions, including expiration or termination of the Hart‑Scott‑Rodino waiting period, approval from the U.S. Nuclear Regulatory Commission for transfer of a nuclear export license, absence of prohibitive governmental orders, and accuracy of representations and compliance with covenants.
