FOR IMMEDIATE RELEASE

PerkinElmer Completes Acquisition of Caliper Life Sciences

WALTHAM, Mass. – November 7, 2011 – PerkinElmer, Inc. (NYSE: PKI), a global leader focused on improving the health and safety of people and the environment, today announced that the Company has completed its acquisition of Caliper Life Sciences, Inc. (NASDAQ: CALP), a Hopkinton, Massachusetts-based leader in imaging and detection solutions for life sciences research, diagnostics and environmental markets. In September, PerkinElmer announced its intent to acquire Caliper for $10.50 per share, for a total net purchase price of approximately $600 million in cash.

Robert F. Friel, chairman and chief executive officer, PerkinElmer, said, “The integration of Caliper into our organization will further strengthen PerkinElmer’s position in personalized medicine. The acquisition will enhance our ability to provide customers with the complementary technologies, services and knowledge they need to drive innovation from in vivo to in vitro imaging, and provide expanded offerings across our biomedical, diagnostics, environmental and food safety end-markets.”

Friel added, “I am also very pleased to welcome Kevin Hrusovsky, who was Caliper’s CEO, to PerkinElmer. Kevin will lead a newly combined $500 million business, which integrates the former Caliper organization with PerkinElmer’s existing research business. Kevin’s deep industry expertise and successful track record in leading Caliper will provide PerkinElmer with an even stronger foundation as we help customers to develop life-saving and enhancing diagnostics and therapeutics.”

Kevin Hrusovsky said, “We are very excited about the opportunities ahead of us following the combination of two highly successful businesses. Our shared vision for giving customers the tools and insights they need to understand the origins of disease, create new therapies, and transform personalized medicine, is a compelling road map for success as we move forward together.”
