Comprehensive Care Corp. to Buy Pennsylvania Firm: The Costa Mesa health-care management company said it plans to buy Mustard Seed Corp., a Fort Washington, Pa., provider of mental health and substance abuse services, for an undisclosed amount of common stock. The purchase, which requires approval of CompCare shareholders, would boost the company’s annual revenue by roughly 70% to $55 million, said Drew Q. Miller, its chief operating officer. Mustard Seed, a privately held company that serves about 140,000 people, has been losing money recently, though officials declined to offer details. The proposal comes as CompCare faces several challenges to turn itself around financially. The company has been waiting nearly five months for the Securities and Exchange Commission to approve its payout plan to holders of $9.5 million worth of its bonds in default.
