Explanation of Responses:

1. Restricted stock units (RSU) awarded under the Exelon Long Term Incentive Plan (LTIP). Award vests in 1/3 increments at the January or February meeting of the Exelon Compensation Committee with each RSU representing the right to receive one share of Exelon common stock upon vesting. RSUs accrue quarterly dividend equivalents in the form of additional RSUs representing common stock dividends as approved by the Board, which vest on the same schedule as the underlying RSU.

2. In connection with the separation of Constellation Energy Corp (Constellation) from Exelon effective February 1, 2022 (the Spin-Off), the unvested balance of RSU awards outstanding immediately prior to the Spin-Off were adjusted to preserve their intrinsic value post-Spin Off. As a result, the balance of this RSU award accrued an additional 2,085 RSUs. Such adjustment is exempt from Section 16 of the Securities Exchange Act of 1934, as amended (Exchange Act) pursuant to Rule 16a-9 under the Exchange Act. The award will continue to vest on its original schedule and otherwise has substantially the same terms and conditions as the original award.

3. Identical adjustment as described in Note 2. As a result, the balance of this RSU award accrued an additional 6,634 RSUs. Such adjustment is exempt from Section 16 of the Securities Exchange Act of 1934, as amended (Exchange Act) pursuant to Rule 16a-9 under the Exchange Act. The award will cliff vest on December 31, 2023 and otherwise has substantially the same terms and conditions as the original award.
