The chain also expanded in to Utah, with stores in Sandy, Murray, Taylorsville, Provo, Ogden, Layton, and West Jordan. The company hit $1 billion in sales on the strength of 87 stores in 1988.

Also in 1997, Phar-Mor split from ShopKo, and ShopKo bought out all of SuperValu's stock in the company. ShopKo also banned all tobacco products from its stores. In 1998 the company acquired Venture Stores in Kentucky, Iowa, Missouri, Illinois and Kansas. In 1999, William Podany became President of ShopKo. He led the acquisition of 147 Pamida stores later that year. ShopKo also launched spin-off pharmaceutical company ProVantage on to the stock market.
