Adjusted net income effective tax rate of 25.0% for 2026 (all periods).

Does not include any further share repurchases that have been or may be consummated beyond the approximately $260 million repurchased through Q3.

1 The Company's adjusted net income guidance, which is a non-GAAP measure, excludes unrealized gains and losses on financial instruments, net foreign currency gains and losses, acquisition-related intangible amortization, other acquisition and divestiture related items, stock-based compensation, other costs, debt restructuring costs and debt issuance cost amortization, tax related items and certain other non-operating items and non-recurring or non-cash operating charges that are not core to our operations, as applicable depending on the period presented. We are unable to reconcile our adjusted net income guidance to the comparable GAAP measure without unreasonable effort because of the difficulty in predicting the amounts to be adjusted, including, but not limited to, foreign currency exchange rates, unrealized gains and losses on financial instruments, and acquisition and divestiture-related items, which may have a significant impact on our financial results.

The following tables include estimated revenue and ANI per diluted share sensitivities to changes in PPG and interest rates as of the date of this presentation. As a reminder, the impacts of these macro factors can and will change based upon various factors, including material volatility in fuel prices and the composition of our balance sheet. We target maintaining a materially neutral ANI per share impact from 100 bps adjustments to interest rates and can adjust our profile through balance sheet strategies and hedging.
