TMO acquires PPD for $47.50/sh cash—a 24% premium to Tuesday’s “unaffected” closing price and a 35% premium to PPD’s Feb 20 IPO price: https://finance.yahoo.com/news/thermo-fisher-scientific-acquire-ppd-110000105.html Including the assumption of debt, the deal value is $20.9B. TMO is a classic roll-up company, so the usual caveats for such business models apply. PPD (then traded as PPDI) went private in 2011 (#msg-67625255) and then re-IPOd in Feb 2020 (#msg-153676503).
