Meanwhile, within the Diagnostics and Healthcare end market, the company reported strong growth in its Specialty Diagnostics businesses. For the full year, growth in this end market was flat overall, with solid contributions from the transplant diagnostics and immunodiagnostics businesses.

During 2025, the company deployed approximately $16.5 billion, including committing $13 billion to M&A. Thermo Fisher expects to deliver $125 million in adjusted operating income synergies in the next five years, driven by revenue synergies and cost efficiencies.
In October 2025, Thermo Fisher entered into a definitive agreement to acquire Clario Holdings, Inc., a leading provider of endpoint data solutions for clinical trials, for $8.875 billion in cash at close. The acquisition deal is expected to be accretive to adjusted EPS by approximately $0.45 in the first 12 months of ownership.

What Ails Thermo Fisher?
Exposure to Foreign Currency: International markets contribute a substantial portion of Thermo Fisher’s revenues. The company intends to continue expanding its presence in these regions. International revenues and costs are subject to the risk that fluctuations in exchange rates could adversely affect a company’s reported revenues and profitability when translated into U.S. dollars for financial reporting purposes.

As Thermo Fisher’s international sales grow, exposure to fluctuations in currency exchange rates could have a larger effect on its financial results. While foreign exchange provided a 1% year-over-year benefit to sales in the fourth quarter of 2025, any reversal in currency trends could immediately pressure reported growth going forward.
Tough Competitive Pressure: On account of its diversified portfolio, Thermo Fisher faces different types of competitors, including a broad range of manufacturers and third-party distributors. The competitive landscape is quite tough with changing technology and customer demands that require continuing research and development.
