CMC Industries, a provider of contract manufacturing services to OEMs in the telecommunications, computer, and electronics industries, has received notification from Micron Electronics that the computer maker intends to terminate its manufacturing relationship with the Santa Clara-based company. CMC, which owed 21 percent of its revenue to Micron during its last fiscal year, said in a statement that termination of the Micron relationship may have "a material adverse effect" on its business and future earnings.
