Alliance Imaging Acquired by Apollo

Anaheim-based Alliance Imaging Inc., the nation’s biggest mobile operator of magnetic resonance imaging machines, said it has agreed to be acquired by an affiliate of Apollo Management for $258 million. The mostly cash acquisition would position Alliance to become the major buyer in the quickly consolidating industry of mobile MRI diagnostic units, said Terrence M. White, the company’s chief financial officer. At the same time, the company reported big gains in second-quarter revenue and net income, continuing its rebound from the early 1990s when huge losses gave the company a bleak future. Its quarterly earnings grew 41% to $2.4 million.
