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 (MIR) is offering Class A common stock and is concurrently pursuing a convertible notes offering and incremental debt to fund a proposed all-cash acquisition of Paragon Energy Solutions for $585.0 million. The prospectus describes a share offering (public offering price example $21.35) that would cause $1.73 per‑share immediate net tangible book value dilution at that price and discloses a concurrent convertible notes offering of $325.0 million (or $375.0 million if upsized). Management expects to use net proceeds from the equity and convertible notes offerings, after paying approximately $32.9 million for capped call transactions, to fund the acquisition and for general corporate purposes. The company also has existing credit facilities ($450.0 million term loan and $175.0 million revolver) and commitments for an Incremental Term Loan Facility up to $585.0 million to backstop financing. Key transaction terms disclosed include an initial conversion rate of 34.6951 shares per $1,000 principal (≈ $28.82 conversion price) for the notes and a capped call cap price of $42.70. The filing emphasizes material risks including significant leverage and cash required to service debt, potential volatility and dilution from future issuances, geopolitical and trade risks, supply‑chain and IT/cybersecurity risks, and uncertainty that the acquisition or concurrent financings will be completed on the disclosed terms.
