Explanation of Responses:

Id	Content
F1	Represents the number of shares of Common Stock that were acquired on vesting of the performance stock units ("PRSUs") granted on September 16, 2024, upon the achievement of the first of three pre-established stock price hurdles over a performance period beginning on September 16, 2024, and ending on December 31, 2028 (the "Performance Period") and the satisfaction of the time-based vesting condition
F2	Includes 16,201 unvested RSUs.
F3	Represents shares withheld to satisfy tax withholding obligations.
F4	Each PRSU represents a contingent right to receive one share of Common Stock. The number of shares of Common Stock that will be acquired on vesting of the PRSUs is contingent upon the achievement of pre-established stock price hurdles during the Performance Period. Notwithstanding the date of achievement of the stock price hurdles during the Performance Period, the PRSUs subject to the second and third stock price hurdles may not vest until the second and third anniversary of the grant date, respectively, which requires continued service through such date.
