ICON Secures Upgraded Credit Rating from Moody’s Investors Service

DUBLIN–(BUSINESS WIRE)–ICON plc (NASDAQ: ICLR), a world-leading healthcare intelligence and clinical research organization, today announced that Moody’s Investors Service (“Moody’s”) upgraded all of ICON plc’s instrument ratings to Baa3 with a stable outlook. This reflects the stronger credit profile of the ICON Group, which Moody’s now views as comparable in aggregate to Baa3 peers. The Baa3 rating of all the instruments reflects Moody’s view that the ICON Group has reached an investment grade financial profile.

Moody’s highlighted in their report that the upgrade of the debt instruments reflects “Moody’s expectation of ICON’s continued good operating performance and conservative financial strategy and risk management policies, a governance consideration under Moody’s ESG framework, and key to the rating action”.

Brendan Brennan, ICON’s Chief Financial Officer, commented: “We are proud of the investment grade rating upgrade from Moody’s, which goes alongside our recent upgrade from S&P and is aligned with our stated long-term capital allocation priorities for ICON. These upgrades and the strong financial position of the company should enable a re-structuring of our overall debt allowing us to significantly reduce our interest cost going forward.”
