DETROIT – Compuware announced it will sell three of its business units representing roughly 25 percent of its total revenues in a $160 million deal with Marline Equity Partners of Los Angeles. The transaction is expected to close later this month.

The businesses are Changepoint, Uniface, and Compuware?s professional services organization. Altogether they employ about 1,250 people, of whom 633 work in downtown Detroit. Those jobs are expected to stay in Detroit, said Lisa Elkin, a Compuware senior vice president.

Compuware CEO Robert Paul said in a statement that the deal represents a further step in the company?s ongoing reorganization plan. The state?s largest pure play computer software and services company has been under pressure from activist shareholders to sell non-core business units such as those involved in this deal.

Compuware has been undertaking an aggressive corporate restructuring, including cutting at least 160 jobs last year. The company has been under pressure from activist shareholders that contend the company?s is not performing up to par. Compuware has fielded buyout offers, but rejected them as too low.
