A report from investment bank Berkery Noyes on M&A in information and tech companies serving pharma and healthcare says third-quarter transaction volume slowed 6% vs. Q2.

Transaction value rose 245%, a jump attributed to Blackstone Group’s announced third-quarter acquisition of medical data services firm Emdeon for $3.03 billion, 2011’s largest transaction so far. The quarter’s most active acquirer was PerkinElmer.

“The need to integrate scientific tools, effectively manage knowledge, and organize workflow within laboratory settings is becoming even more crucial for clients of organizations such as PerkinElmer,” said managing director Jeffrey Smith.
