(“Thermo Fisher”) and Solventum Corporation (“Solventum”) entered into an agreement, pursuant to which, subject to the satisfaction or waiver of specified conditions, Thermo Fisher agreed to acquire Solventum’s purification and filtration business for approximately $4.1 billion in cash.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements that involve a number of risks and uncertainties. Words such as "believes," "anticipates," "plans," "expects," "seeks," "estimates," and similar expressions are intended to identify forward-looking statements, but other statements that are not historical facts may also be deemed to be forward-looking statements. Important factors that could cause actual results to differ materially from those indicated by forward-looking statements include risks and uncertainties relating to: any natural disaster, public health crisis or other catastrophic event; the need to develop new products and adapt to significant technological change; implementation of strategies for improving growth; general economic conditions and related uncertainties; dependence on customers' capital spending policies and government funding policies; the effect of economic and political conditions and exchange rate fluctuations on international operations; use and protection of intellectual property; the effect of changes in governmental regulations; and the effect of laws and regulations governing government contracts, as well as the possibility that expected benefits related to recent or pending acquisitions, including the proposed acquisition of Solventum’s purification and filtration business, may not materialize as expected; the proposed acquisition of Solventum’s purification and filtration business being timely completed, if completed at all; regulatory approvals required for the transaction not being timely obtained, if obtained at all, or being obtained subject to conditions; Solventum’s purification and filtration business experiencing disruptions as a result of the acquisition or due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, customers, other business partners or governmental entities; difficulty retaining key employees; the outcome of any legal proceedings related to the proposed acquisition of Solventum’s purification and filtration business; and the parties being unable to successfully implement integration strategies or to achieve expected synergies and operating efficiencies within the expected time-frames or at all. Additional important factors that could cause actual results to differ materially from those indicated by such forward-looking statements are set forth in Thermo Fisher's most recent annual report on Form 10-K, which is on file with the U.S. Securities and Exchange Commission ("SEC") and available in the "Investors" section of Thermo Fisher's website, ir.thermofisher.com, under the heading "SEC Filings". While Thermo Fisher may elect to update forward-looking statements at some point in the future, Thermo Fisher specifically disclaims any obligation to do so, even if estimates change and, therefore, you should not rely on these forward-looking statements as representing Thermo Fisher’s views as of any date subsequent to today.
