Explanation of Responses:

Id Content
F1 On December 14, 2022, the reporting person filed a Form 4 which inadvertently attributed a stock option exercise to the incorrect stock option award. The stock option that was the subject of the reported exercise is the stock option award originally reported on September 9, 2021. Accordingly, the first line of Table 2 of this Form 4 reflects this correction.
F2 The stock option exercise was effected pursuant to a Rule 10b5-1 trading plan.
F3 The option award vests upon the achievement of a closing price hurdle following Beam Therapeutics Inc.'s initial public offering (which closing price hurdle has been achieved) in three equal installments on December 21, 2021, June 30, 2022 and December 31, 2022.
