Moody’s affirms Mirion’s B1 rating, upgrades senior secured debt

Moody's affirmed Mirion Technologies' B1 corporate family rating and upgraded its senior secured bank credit facility to Ba2 with a stable outlook, following the company's $585 million acquisition of Paragon Energy Solutions. This deal, funded by a new $250 million convertible bond and equity, significantly expands Mirion's nuclear market presence but increases pro forma leverage to approximately 5x. Moody's anticipates future deleveraging towards 4.5x by 2026, supported by robust growth in nuclear power and cancer care markets, and a strong recurring revenue base, offsetting initial leverage concerns.

Analysis

Moody's has affirmed Mirion Technologies' (MIR) B1 corporate family rating while upgrading its senior secured bank credit facility to Ba2 from Ba3, signaling confidence in the company's trajectory despite a significant increase in leverage. The rating action follows Mirion's $585 million acquisition of Paragon Energy Solutions, a strategic move to expand its presence in the US nuclear sector, including the high-growth small modular reactor market. This transaction is being funded by a new $250 million senior unsecured convertible bond and an equity issuance, which will elevate pro forma debt-to-EBITDA to approximately 5.0x from 4.0x. The upgrade to the senior secured debt reflects an improved recovery outlook for those lenders due to the introduction of more junior debt in the capital structure. Moody's anticipates this leverage will decline towards 4.5x by 2026, supported by strong order growth from the nuclear and cancer care markets, a sizable recurring revenue base, and a healthy backlog. While the company faces headwinds from softer demand in its Labs and Research markets and macroeconomic uncertainty, its liquidity profile remains good, with expected free cash flow exceeding $90 million over the next year and access to a $175 million revolving credit facility.

Key Decisions for Investors

• Equity investors must weigh the immediate risk of heightened financial leverage, now at 5x debt-to-EBITDA, against the long-term strategic value of the Paragon acquisition, which strengthens Mirion's position in high-barrier nuclear markets.
• Credit investors in the senior secured facility should view the upgrade to Ba2 as a positive structural enhancement, as the new junior convertible debt improves their position and potential recovery in a downside scenario.
• Investors should closely monitor the company's execution on deleveraging and integration of the new acquisition, as achieving the projected reduction in leverage to 4.5x by 2026 is critical to validating the current stable outlook and investment thesis.
• Potential risks to monitor include any further deterioration in the Labs and Research markets or failure to realize margin expansion, which could impede the company's ability to generate the free cash flow needed for deleveraging.
