Thermo Fisher Scientific, one of the world's largest scientific instrumentation companies, closed its $8.875 billion cash purchase of Clario Holdings on March 24, 2026. Clario provides the digital tools that pharmaceutical companies use to collect patient data during clinical trials — technology that has contributed to roughly 70 percent of drugs approved by the Food and Drug Administration (FDA) over the past decade. The deal, first announced in October 2025, also includes up to $525 million in additional payments tied to Clario's near-term performance, bringing the total potential price to approximately $9.4 billion.
The acquisition is the latest in a series of large deals through which Thermo Fisher has assembled a one-stop platform for drug development. The company now controls a contract research organization (PPD, acquired for $17.4 billion in 2021), a contract drug manufacturer (Patheon, acquired for $7.2 billion in 2017), and Clario's clinical trial data technology — a combination no competitor currently matches. For Clario's private equity owners, Astorg and Nordic Capital, the sale represents one of the largest healthcare buyout exits of 2025 and a substantial return after roughly doubling Clario's revenue during their ownership.
