Ciber Inc. (NYSE: CBR), a Greenwood, Colo.-based IT staffing and solutions firm, nominated Mark Lewis as a new independent director for election at its 2015 annual meeting of stockholders.

Lewis will be nominated together with incumbent director Richard Coleman as Class III directors. In connection with the nominations, Ciber has reduced the size of the board to eight directors from nine. In light of the recent changes to the board, including the nomination of Lewis and re-nomination of Coleman, Lone Star Value Investors LP and its affiliates withdrew its nomination of directors to the board.

The company earlier this month announced it will add three new independent directors to its board.
