Molina Healthcare has lost two key state contracts recently, and its stock has tumbled. The company, which serves exclusively as a managed-care plan for government programs such as Medicaid and Medicare, said these were only temporary set backs. Healthcare companies are competing to profit from a flood of government contracts for treating the poor and disabled, and Molina, a family-run company in Long Beach with nearly $5 billion in revenue is trying to stay ahead of the pack according to a recent report in the Los Angeles Times.
