### Footnotes:

(1) Represents 1,110,943.375 shares withheld to cover the exercise price of Groupon, Inc. (the "Issuer") Common Stock, and 236,241.625 shares withheld to satisfy the mandatory tax withholding requirements, resulting in a net settlement of 1,715,315 shares. This is not an open market sale of securities.

(2) Represents securities directly owned by Pale Fire Capital SICAV a.s. ("PFC SICAV"). Pale Fire Capital SE, as the controlling person and sole shareholder of PFC SICAV, may be deemed to beneficially own the securities directly owned by PFC SICAV. Mr. Barta, as a control person and Chairman of the supervisory board of Pale Fire Capital SE, may be deemed to beneficially own the securities directly owned by PFC SICAV. Mr. Senkypl, as a control person and Chairman of the board of Pale Fire Capital SE, may be deemed to beneficially own the securities directly owned by PFC SICAV.

(3) Represents securities directly owned by Pale Fire Capital SE. Mr. Barta, as a control person and Chairman of the supervisory board of Pale Fire Capital SE, may be deemed to beneficially own the securities directly owned by Pale Fire Capital SE. Mr. Senkypl, as a control person and Chairman of the board of Pale Fire Capital SE, may be deemed to beneficially own the securities directly owned by Pale Fire Capital SE.

(4) On March 30, 2023 (the "Grant Date"), the Issuer granted Mr. Senkypl nonqualified stock options (the "Stock Options") to purchase shares of Common Stock at a per share exercise price of $6.00 under the Issuer's 2011 Incentive Plan, as amended (the "Plan"). A majority vote of the Issuer's stockholders subsequently approved an amendment to the Plan at the Issuer's 2023 Annual Meeting of Stockholders, pursuant to which the Stock Options would vest and be exercised prior to the first anniversary of the Grant Date. Accordingly, one eighth (1/8th) of the Stock Options vested on June 30, 2023 and the remainder vested in substantially equal quarterly installments over the next seven (7) quarters. As of December 31, 2025, all 3,062,500 options were fully vested.

(5) The Stock Options have a contractual expiration date of March 30, 2026. Pursuant to the terms of the
Plan, if the expiration date of an option falls during a blackout period, the expiration date is automatically extended until 30 calendar days after the end of such blackout period. As the contractual expiration date of March 30, 2026 fell during a blackout period, the Stock Options remained exercisable until June 15, 2026.
