Grainger to Withdraw Chicago Stock Exchange Listing, Retains NYSE Listing

Grainger announced plans to voluntarily withdraw the listing of its common stock from the Chicago Stock Exchange. Grainger's common stock will continue to be listed on the New York Stock Exchange (NYSE). Grainger has decided to withdraw its listing from the Chicago Stock Exchange to eliminate duplicative administrative requirements and costs inherent with dual listings. The withdrawal is expected to be effective next month. Grainger does not believe that withdrawing its listing from the Chicago Stock Exchange will have any effect on the liquidity of its common stock. The Chicago Stock Exchange will continue to trade Grainger common stock on an unlisted trading privilege basis.
