Explanation of Responses:

Id	Content
F1	Restricted stock units convert into common stock on a one-for-one basis.
F2	Reflects the amount of shares beneficially owned, including shares received due to automatic dividend reinvestment, as of the date of this report.
F3	On March 1, 2022, the reporting person was granted 47,438 restricted stock units that vest in five equal annual installments beginning March 1, 2023, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
F4	On March 1, 2024, the reporting person was granted 16,490 restricted stock units that vest in three equal annual installments beginning March 1, 2025, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
F5	On March 3, 2025, the reporting person was granted 34,697 restricted stock units of which 6,497 vest in three equal annual installments beginning March 3, 2026, after market close, and 28,200 vest after 3 years, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
F6	On March 2, 2026, the reporting person was granted 7,099 restricted stock units that vest in three equal annual installments beginning March 2, 2027, subject to continued service. Vested shares will be issued to the reporting person as soon as practicable after the vesting date.
F7	The reporting person's immediately preceding Form 4, filed on March 3, 2026, inadvertently understated the amount of securities beneficially owned following reported transaction(s) by 16,961 common shares. The understatement was the effect of a clerical error as the calculation omitted 16,961 directly held shares that were acquired on March 1, 2026 and reported on prior Form 4s. The amount shown in this table corrects the inadvertent exclusion.
