King Pharmaceuticals vs. Alpharma
In August 2008, King Pharmaceuticals tried to woo Alpharma with $1.38 billion cash offer. King wasn't prepared to take no for an answer, and it was ready to get hostile if necessary to push the acquisition through.
But Alpharma wasn't as enthusiastic and rejected the offer. Alpharma claimed it had other companies interested in a buyout, but King pushed forward with the hostile bid. King also threatened a proxy battle if Alpharma continued to reject its offers.
Despite Alpharma's repeated objections, a $1.6 billion offer eventually piqued its interest.
