Explanation of Responses:

( 1 )The shares reported represent common shares purchased from the Issuer by the Reporting Person upon exercise of his investment rights pursuant to the Issuer's 2025 Bonus Swap Program under its 2023 Omnibus Incentive Plan ("2023 Plan"). The Reporting Person elected to use 50% of his 2025 net bonus to purchase common shares at a purchase price of $68.81 per share ("Investment Shares"). ( 2 )Pursuant to the Issuer's 2023 Plan, the purchase price of the Investment Shares is calculated based on the last sales price of common shares of the Issuer reported on the New York Stock Exchange on the trading day immediately preceding the grant date, in this case February 24, 2026. ( 3 )Each Restaurant Brands International Limited Partnership exchangeable unit is convertible, at the Reporting Person's election, into common shares of Restaurant Brands International Inc. or a cash amount equal to a prescribed cash amount determined by reference to the weighted average trading price of Restaurant Brands International Inc.'s common share on the New York Stock Exchange for the 20 consecutive trading days ending on the last business day prior to the exchange date, at the sole discretion of the general partner of Restaurant Brands International Partnership (subject to the consent of the Restaurant Brands International Inc. conflicts committee, in certain circumstances). This conversion right has no expiration date. ( 4 )These options are fully vested and exercisable. ( 5 )Each restricted share unit represents a contingent right to receive one common share. ( 6 )These restricted share units vest in equal annual installments. The remaining vesting will occur on December 15, 2026. ( 7 )These restricted share units vest in equal annual installments. The remaining vestings will occur on December 15, 2026 and December 15, 2027. ( 8 )The shares reported represent an award of performance based restricted share units ("2024 PBRSUs") granted to the Reporting Person. The 2024 PBRSUs will have a performance period beginning February 23, 2024 and ending February 23, 2027 and to the extent earned will vest on March 15, 2027. The number of common shares that will be earned at the end of the performance period is subject to increase or decrease based on the results of the performance condition. ( 9 )These restricted share units vest in equal annual installments. The remaining vestings will occur on December 15, 2026, December 15, 2027 and December 15, 2028.

The number of common shares that will be earned at the end of the performance period is subject to increase or decrease based on the results of the performance condition. ( 11 )The Issuer granted the 2026 restricted share units ("2026 RSUs") to the Reporting Person pursuant to the Issuer's 2025 Bonus Swap Program under its 2023 Plan. The Reporting Person elected to use 50% of his 2025 net bonus to purchase Investment Shares and received a matching grant of 2026 RSUs in an amount equal to 50% of his gross bonus, multiplied by a multiplier based on the Reporting Person's position level with the Issuer ("RSU Multiplier"), and divided by the purchase price of $68.81 per share. The RSU Multiplier was 2.25 for executive vice presidents and above. If the Reporting Person sells any of the Investment Shares, he will forfeit all of the 2026 RSUs that have not yet vested. ( 12 )These restricted share units vest in equal annual installments. The vestings will occur on December 15, 2026, December 15, 2027, December 15, 2028 and December 15, 2029. ( 13 )The shares reported represent an award of performance based restricted share units ("2026 PBRSUs") granted to the Reporting Person.
