FX-adjusted information assumes a constant exchange rate between the periods being compared for purposes of currency translation into U.S. dollars (e.g., assumes the foreign exchange rates used to determine results for the current period apply to the corresponding prior year period against which such results are being compared). Management believes the presentation of information on an FX-adjusted basis is helpful to investors by making it easier to compare the Company’s performance in one period to that of another period without the variability caused by fluctuations in currency exchange rates. 2) Attributable to common shareholders.

We continue to engage with our shareholders to solicit and consider feedback in addition to focusing on the following:  Aligning our executive compensation programs with the Company’s strategic goals and long-term success  Engaging with stakeholders and actively incorporating feedback from shareholders when considering program or disclosure enhancements  Using a balanced scorecard with metrics across a range of categories to drive strong Company performance  Focusing on strong governance practices in our executive compensation programs  Discouraging imprudent risk-taking including, where appropriate, making adjustments to incentive outcomes  Regular discussions with the Compensation & Benefits Committee (CBC) to review performance and executive pay Our Compensation Program and Our Commitment to Shareholders 6 Our Board continues to consider the long-term interests of the Company and shareholders when making decisions regarding our compensation programs

2023 Shareholder Feedback What We Heard 2022 Special Award The use of special awards is disfavored, particularly for the CEO The award lacked sufficiently rigorous performance conditions or rationale that would have mitigated concerns, and the measurement period for TSR should have been for a longer period of time CEO Pay The pace of CEO pay increases in recent years has been elevated without sufficient rationale Short-Term Incentive Program Disclosure of how AIA goals are set and how performance is measured is limited, and it is difficult to assess how outcomes were achieved Financial objectives/quantitative goals are weighted at less than 50% of the AIA scorecard Individual performance disclosures particularly on the individual multiplier require additional explanation 8

How We Have Responded to Shareholder Feedback 9 2024 Proxy Disclosures and Responsiveness to 2023 Say-on-Pay Vote •Special Awards will no longer be awarded for Mr. Squeri •No Special Awards granted through 2023 to other NEOs and none are currently being considered •No changes to CEO target pay for 2024 •Enhanced disclosures around our AIA program and performance – Additional detail on goal setting and performance determination introducing our 100% AIA achievement level with intra-category metric weightings detailed for transparency – Detailed how each quadrant of our scorecard links to shareholder, customer, and enterprise value – Performance outcomes that warrant our Company Performance Multiplier of 130% •Individual Performance Highlights for each NEO New for 2024 •Beginning in 2024, the Compensation and Benefits Committee increased the weighting of our Shareholder quadrant (i.e., financial objectives) from 45% to 60%, increasing the weight towards quantifiable financial objectives. As a result, the weightings for our other quadrants will shift to the following: Customer (10%) Colleague (10%), and Strategic (20%). Shareholder feedback was delivered to our Board and has led to modifications in our executive compensation programs, governance practices and disclosures.
