*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Reflects the partial payout of performance shares originally awarded to the reporting person on February 20, 2015. Vesting of the performance shares was dependent on Chipotle's comparative achievement versus restaurant industry peer companies in average annual growth in sales, net income and shareholder return over the period from January 1, 2015 through December 31, 2017. The Compensation Committee of Chipotle's Board of Directors certified the level of achievement versus the peer group on March 15, 2018, resulting in partial vesting of the performance shares.
(2)	Reflects the satisfaction of performance conditions on performance-vesting stock-only stock appreciation rights, or Performance SOSARs, originally granted to the reporting person on February 3, 2014. Vesting of the second tranche of Performance SOSARs was contingent on Chipotle's achievement of stated levels of cumulative cash flow from operations prior to the fifth fiscal year-end following the award date, with vesting to occur no sooner than February 3, 2017, subject to possible acceleration. The Compensation Committee of Chipotle's Board of Directors certified the achievement of the performance target on March 15, 2018, resulting in vesting of the second tranche of 2014 Performance SOSARs.
(3)	The first tranche of the 2014 Performance SOSARs vested and became exercisable as of May 10, 2016.
(4)	One half of the 2014 Stock Appreciation Rights vested and became exercisable on February 3, 2016, and the remaining half vested and became exercisable on February 3, 2017.
(5)	One half of the 2013 Performance SOSARs vested and became exercisable on February 7, 2015, and the remaining half vested and became exercisable on May 10, 2016.
(6)	One half of the 2013 Stock Appreciation Rights vested and became exercisable on February 7, 2015, and the remaining half vested and became exercisable on February 7, 2016.
