Thermo Fisher Scientific Inc. (NYSE: TMO), the world leader in serving 
      science, today announced that it has signed a definitive agreement to 
      acquire One Lambda, the leader in transplant diagnostics, for $925 
      million in cash, subject to a post-closing adjustment. The purchase 
      price includes the cost of a three-year retention program established by 
      One Lambda for the benefit of key employees, amounts payable to certain 
      shareholders for noncompetition agreements, and a one-year earn-out 
      provision based on the achievement of certain financial targets. The 
      transaction, which is expected to be completed in the fourth quarter of 
      2012, is expected to be immediately accretive upon close and add $0.09 
      to $0.11 to Thermo Fisher's 2013 adjusted earnings per share (EPS).
Founded in 1984 by Dr. Paul Terasaki, a pre-eminent researcher in the 
      field of transplantation, One Lambda is a pioneer in transplant 
      diagnostics. One Lambda's diagnostic tests are used by transplant 
      centers for tissue typing, primarily to determine the compatibility of 
      donors and recipients pre-transplant, and to detect the presence of 
      antibodies that can lead to transplant rejection. One Lambda is 
      privately held and has approximately 320 employees, primarily based in 
      Canoga Park, Calif., who serve more than 1,400 laboratories worldwide. 
      The business, which generated revenue of $182 million in 2011, will 
      become part of Thermo Fisher's Specialty Diagnostics Segment.
    
    
      "One Lambda is an exciting addition to our specialty diagnostics 
      portfolio," said Marc N. Casper, president and chief executive officer 
      of Thermo Fisher. "The One Lambda team has pioneered market-leading 
      tests that are widely used across the transplant-testing workflow to 
      improve patient outcomes. With its strong technology platform, high 
      margin profile and good growth prospects, the business is perfectly 
      aligned with our specialty in vitro diagnostics strategy.
    
    
      "One Lambda gives us access to the attractive transplant diagnostics 
      market and complements our existing immunosuppressant monitoring assays. 
      It also offers the opportunity to leverage our global commercial 
      infrastructure to serve growing transplant needs in emerging markets. 
      From a financial perspective, we expect One Lambda to be immediately 
      accretive to our adjusted EPS and to yield a strong return on invested 
      capital."
    
    
      George M. Ayoub, co-founder, president and chief executive officer of 
      One Lambda, said, "We are excited about the opportunities ahead as we 
      join Thermo Fisher's specialty diagnostics business. I believe that, 
      together, we will increase the use of human leukocyte antigen (HLA) 
      typing and antibody detection to accelerate growth and improve the 
      success rate of transplantation. Importantly, we will continue to 
      fulfill our mission, which is to improve the quality of life for 
      transplant patients and their families."
    
    
      Casper added, "We look forward to welcoming the One Lambda team to the 
      Thermo Fisher family. We are also pleased to announce that we will 
      collaborate with Dr. Terasaki and the Terasaki Foundation Laboratory, 
      which continues to support groundbreaking research in preventing 
      post-transplant rejection."
    
    
      Benefits of the Transaction
    
    
      - 
        Enhances Thermo Fisher's Presence in Specialty in vitro 
        Diagnostics: Growth in the transplant diagnostics market is being 
        driven by increasing global demand for transplant procedures and 
        post-transplant patient monitoring. This specialized technology 
        supports a broad portfolio of high-margin reagents in the two major 
        categories of transplant testing: HLA typing and antibody detection.
      
 
      - 
        Adds New Capabilities to Complete the Transplant-Testing Workflow: 
        One Lambda's leading diagnostic tests for HLA typing and antibody 
        detection pre- and post-transplant will complement Thermo Fisher's 
        existing immunosuppressant assays that are used for monitoring drug 
        therapies in post-transplant patients to prevent transplant rejection.
      
 
      - 
        Creates Opportunities to Leverage Thermo Fisher's Commercial 
        Infrastructure in Emerging Markets: Thermo Fisher expects to 
        leverage its extensive commercial capabilities in emerging markets to 
        accelerate growth in One Lambda's existing product portfolio, which is 
        currently marketed primarily to physicians and laboratories in the U.S.
      
 
      - 
        Offers Compelling Financial Benefits: The transaction is 
        expected to be immediately accretive to Thermo Fisher's adjusted EPS 
        upon close, and accretive by $0.09 to $0.11 per share in 2013. It is 
        also expected to generate revenue and cost synergies for a total 
        adjusted operating income1 benefit of approximately $15 
        million in 2015. In addition, the transaction will result in greater 
        tax efficiencies by leveraging Thermo Fisher's global structure.
Thermo 
        Fisher and One Lambda expect to make an election under section 
        338(h)(10) of the Internal Revenue Code that will increase Thermo 
        Fisher's tax basis in the acquired assets. This election will result 
        in annual cash tax savings of approximately $19 million over 15 years, 
        yielding a net present value benefit of approximately $190 million for 
        Thermo Fisher.
The implied 2011 EBITDA purchase price 
        multiple for One Lambda is approximately 10.9x. Including the tax 
        benefit, the implied 2011 EBITDA purchase multiple is approximately 
        8.7x.
