Enrique Beltranena, President & Chief Executive Officer, said: “With improved visibility into second-half demand drivers and ongoing capacity discipline, we are reinstating our full-year guidance for EBITDAR margin, which we now expect in the range of 32% to 33%. Despite external geopolitical headwinds, our flexible business model and resilient cost structure enable us to moderate growth, remaining prudent and aligned with market trends. Going forward, our capacity decisions will remain anchored in two guiding priorities – customer demand and sustained profitability, and we continue to see meaningful opportunities in our business model and our markets to generate long-term value.”

Supplemental Information on Non-IFRS Measures

We evaluate our financial performance by using various financial measures that are not performance measures under International Financial Reporting Standards (“non-IFRS measures”). These non-IFRS measures include CASM, CASM ex fuel, Adjusted CASM ex fuel, EBITDAR, Net debt-to-LTM EBITDAR, Total cash, cash equivalents and short-term investments. We define CASM as total operating expenses by available seat mile. We define CASM ex fuel as total operating expenses by available seat mile, excluding fuel expense. We define Adjusted CASM ex fuel as total operating expenses by available seat mile, excluding fuel expense, aircraft and engine variable lease expenses and sale and lease back gains. We define EBITDAR as earnings before interest, income tax, depreciation and amortization, depreciation of right of use assets and aircraft and engine variable lease expenses. We define Net debt-to-LTM EBITDAR as Net debt divided by LTM EBITDAR. We define Total cash, cash equivalents and short-term investments as the sum of cash, cash equivalents and short-term investments.

These non-IFRS measures are provided as supplemental information to the financial information presented in this release that is calculated and presented in accordance with International Financial Reporting Standards (“IFRS”) because we believe that they, in conjunction with the IFRS financial information, provide useful information to management’s, analysts and investors overall understanding of our operating performance.

Because non-IFRS measures are not calculated in accordance with IFRS, they should not be considered superior to and are not intended to be considered in isolation or as a substitute for the related IFRS measures presented in this release and may not be the same as or comparable to

similarly titled measures presented by other companies due to possible differences in the method of calculation and the items being adjusted.

We encourage investors to review our financial statements and other filings with the Securities and Exchange Commission in their entirety for additional information regarding the Company and not to rely on any single financial measure.
