_______________________

(1)The diluted weighted-average shares outstanding for the 13 and 26 weeks ended June 29, 2019 did not include performance-based stock options because the requisite performance criteria of such stock options had not been achieved as of that date.

On February 3, 2020, in conjunction with a secondary offering, certain performance criteria were achieved resulting in the vesting of 4.1 million performance-based stock options, and accordingly, these vested performance-based stock options are included in the diluted weighted-average shares outstanding for the 13 and 26 weeks ended June 27, 2020.

On April 27, 2020 in conjunction with an additional secondary offering, certain performance criteria were achieved resulting in the vesting of the remaining 1.7 million unvested performance-based stock options, and accordingly, these vested performance-based stock options are included in the diluted weighted-average shares outstanding for the 13 and 26 weeks ended June 27, 2020. See Note 5 for additional information.
