Egghead Inc, the Issaquah, Washington company that pioneered specialist software retail stores in the US, where it now has 180 of them, has greatly strengthened its top management following poor financial performance since it went public at $17 a share last June – since when the shares have slumped to $11.25 after a high of $21 shortly after the flotation: founder and chairman Victor Alhadeff has passed his posts as president and chief executive to Stuart Sloan, chairman of Quality Food Centers Inc, and has created two executive vice-president positions, both staffed from outside, one to look after the merchandising side, the other to concentrate on corporate development.
