What is a Stalking Horse?

In the distressed M&A context, a stalking horse refers to a potential purchaser participating in a stalking horse auction who agrees to acquire the assets or business of an insolvent debtor as a going concern. In a stalking horse auction of an insolvent business, a preliminary bid by the stalking horse bidder is disclosed to the market and becomes the minimum bid, or floor price, that other parties can then outbid.
