CHICAGO, IL - July 28, 2015 - CBOE Holdings, Inc. (NASDAQ: CBOE) announced that the Chicago Board Options Exchange (CBOE) and C2 Options Exchange (C2) are postponing listing options on Shake Shack, Inc. (ticker symbol: SHAK).

The delay in listing the options is the result of a pre-cautionary measure taken by the exchanges. Specifically, the exchanges expect that one of the listing criteria will become eligible once a secondary offering of the underlying stock is effective. The exchanges will issue a formal notice of the new listing date. This updates yesterday's announcement which said SHAK options would begin trading on Tuesday, July 28.

Shake Shack, founded in 2004, owns, operates and licenses Shake Shack restaurants (called Shacks) in the United States, Europe and Asia. Shacks are modern-day "roadside" burger stands offering hamburgers, hot dogs, crinkle-cut fries, shakes, frozen custard, beer and wine.
