Thermo Buys Life Technologies for $13.6 Billion
Thermo Fisher Scientific (Waltham, Massachusetts) will acquire Life Technologies Corporation (Carlsbad, California) under the terms of a definitive agreement signed earlier this year.
The deal is estimated to be $76.00 per share at a total cost of $13.6 billion. The transaction was reportedly approved by both of the company's board of directors, according to a press release.
Life Technologies is a global biotechnology company and is recognized as a leading player in the development of sequencing technology. The acquisition will place Thermo Fisher as a key competitor in the development of advanced genetic testing, the potential key to personalized medicine.
"We are extremely excited about this transaction because it creates the ultimate partner for our customers and significant value for our shareholders," said Marc N. Casper, president and CEO of Thermo Fisher Scientific.
Gregory T. Lucier, chairman and CEO of Life Technologies, commented, "This transaction brings together two companies intent on accelerating innovation for our customers and achieving greater success in a highly competitive global industry."
Lucier added, "This combination delivers immediate and significant cash value to our stockholders and represents a successful conclusion to the board's strategic review to enhance stockholder value and develop an even stronger future for Life Technologies."
First Institution in India Recognized by Waters Centers of Innovation Program
Waters (Milford, Massachusetts) has announced the selection of the St. John's Research Institute (SJRI, Bangalore, India) — known for its proteomics research — for its Centers of Innovation program. St. John's is the first research institution in India to join the program.
The institute is part of the St. John's Academy of Health Sciences, specifically focused on the improvement of population health. Directed by Amit Kumar Mandal, professor of molecular medicine and clinical proteomics, the center has a reputation for research into blood disorders.
Mandal, as a physical chemist interested in molecular structure, became interested in mass spectrometry in 2005 when encouraged by his professor. "The boss is always right I guess," he said. "I did an internet search and found the citation report for professor John Fenn's paper on electrospray mass spectrometry of large molecules. The citation index growth of this paper convinced everyone that electrospray mass spectrometry was an important breakthrough in science. So I gradually started learning about mass spectrometry. It's made all the difference."
