Like a one-two punch, two major Maryland employers in the health care service and pharmaceutical industries were the targets last week of multibillion-dollar acquisition deals.

Both homegrown companies — Human Genome Sciences Inc. and Catalyst Health Solutions Inc. — are based in Rockville. Both were courted by out-of-state companies.

Human Genome ultimately rebuffed a $2.6 billion offer by biopharmaceutical giant GlaxoSmithKline, saying it was too low. But Catalyst agreed to be acquired by a larger Illinois competitor for $4.4 billion, and Human Genome has officially acknowledged it's on the market.
