Dividend yields are based on Hilton's expected quarterly dividend and the three-month average stock price; however, we suspended the declaration and payment of dividends from March 2020 through April 2022. Risk-free rates are based on the yields of U.S. Department of Treasury instruments with similar expected terms. Expected terms are generally estimated based on the midpoint of the remaining time to vest and the contractual terms of the stock options, consistent with the original approach used at grant, and taking into account the circumstances of the grant at the measurement date and other relevant factors under GAAP. The exercise prices of the stock options that were granted, vested or outstanding during the covered years ranged from $58.02 to $150.67. (b) For PSUs and RSUs, the fair values are based on the closing price of our common stock on the NYSE on the respective year-end or vesting dates, as applicable. For unvested PSUs, fair values were based upon management's best estimate of the projected achievement of our performance metrics as of the respective year-end dates. For vested PSUs, fair values as of the respective vesting dates reflect the valuations described in the "Option Exercises and Stock Vested" tables in our proxy statements for each of the covered years. (c) Relates to the PSUs granted prior to the modification in 2020. (3) Reflects the Standard and Poor's 500 Hotels, Resorts & Cruise Lines Index ("S&P Hotels Index"). (4) Adjusted EBITDA is calculated as set forth in "Part II—Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. See Annex A for additional information and a reconciliation of Adjusted EBITDA to net income, the most comparable GAAP financial measure. | | |

Further, our PSUs are based on management's best estimate of the projected achievement of our performance metrics at the end of each performance period and therefore may not consistently correlate with the Company's financial performance in the respective covered year. | | |

Dividend yields are based on Hilton's expected quarterly dividend and the three-month average stock price; however, we suspended the declaration and payment of dividends from March 2020 through April 2022. Risk-free rates are based on the yields of U.S. Department of Treasury instruments with similar expected terms. Expected terms are generally estimated based on the midpoint of the remaining time to vest and the contractual terms of the stock options, consistent with the original approach used at grant, and taking into account the circumstances of the grant at the measurement date and other relevant factors under GAAP. The exercise prices of the stock options that were granted, vested or outstanding during the covered years ranged from $58.02 to $150.67. (b) For PSUs and RSUs, the fair values are based on the closing price of our common stock on the NYSE on the respective year-end or vesting dates, as applicable. For unvested PSUs, fair values were based upon management's best estimate of the projected achievement of our performance metrics as of the respective year-end dates. For vested PSUs, fair values as of the respective vesting dates reflect the valuations described in the "Option Exercises and Stock Vested" tables in our proxy statements for each of the covered years. (c) Relates to the PSUs granted prior to the modification in 2020. 2022 2021 2020 2019 Valuation Date Stock Price $126.36 - $142.01 $123.13 - $155.99 $93.33 - $113.23 $110.91 Expected Volatility 33.64% - 35.83% 33.48% - 35.34% 21.97% - 35.62% 23.03% - 24.05% Dividend Yield 0.41% - 0.46% 0.00% 0.00% - 0.55% 0.60% Risk-Free Rate 1.69% - 4.04% 0.40% - 1.28% 0.23% - 1.39% 1.63% - 1.69% Expected Term (in Years) 3.5 - 5.2 3.5 - 5.2 3.5 - 5.2 3.6 - 5.2 Fair Value Per Stock Option $36.79 - $68.92 $50.33 - $82.28 $25.57 - $56.39 $39.09 - $54.70 Expected volatility is estimated using a blended approach of historical and implied volatility.
