ICON Public Limited Company (NasdaqGS:ICLR) is looking for M&A. Brendan Brennan Chief Financial Officer said during the Full Year 2023 Earnings Conference Call, "As Steve mentioned, we're pleased to receive the upper grades in our credit ratings from both S&P Global Ratings and Moody's in the fourth quarter. With a return to an investment-grade rating, we now have the ability to more favorably refinance our debt and in turn, free up more capital to deploy opportunistically for M&A as well as potential share repurchase. Our preferred use of capital remains M&A, and we have a healthy pipeline of opportunities we're currently engaged on that are focused on adding scale and capability to strategic areas of our portfolio".
