F1	Each restricted stock unit represents a contingent right to receive one share of Issuer common stock.
F2	These shares were retained by 1stdibs, Inc. ("1stdibs") via settlement on a net withholding basis in order to meet the tax withholding obligations of the reporting person in connection with the vesting of an installment of restricted stock units ("RSUs") granted to the reporting person on June 2, 2022, March 14, 2023, and March 15, 2024. None of these shares were sold in an open market transaction.
F3	Twenty-five percent (25%) of the restricted stock units shall vest on June 8, 2023, provided the Reporting Person continues to have a service relationship with the Issuer at such time. Thereafter, the remaining seventy-five percent (75%) of the restricted stock units shall vest in 12 equal quarterly installments starting on September 8, 2023, provided the Reporting Person continues to have a service relationship with the Issuer at such time. The restricted stock units have no expiration date.
