Risks Related to Ownership of our Senior Notes

The 2023 Series C notes will form a single series with the initial 2023 Series C notes, which have a limited trading market. The 2025 Series I notes are a new issue of securities with no established trading market and we cannot assure that such a market will develop.

Although the initial 2023 Series C notes have traded since their issuance on May 12, 2023, a market for the 2023 Series C 4.875% Senior
Notes due 2028, including the 2023 Series C notes offered hereby, might not continue to be sustained. Moreover, there is no existing market for the 2025 Series I notes, and we do not intend to apply for listing of either series of notes on any
securities exchange. We cannot assure that an active trading market for the notes will develop or be sustained, as applicable. There can be no assurances as to the liquidity of any market that may develop for the notes, the ability of noteholders to
sell their notes or the price at which the noteholders may be able to sell their notes. Future trading prices of the notes will depend on many factors, including, among other things, prevailing interest rates, our operating results and the market
for similar securities. Generally, the liquidity of, and trading market for, the notes may also be materially and adversely affected by declines in the market for similar debt securities. Such a decline may materially and adversely affect such
liquidity and trading independent of our financial performance and prospects.

USE OF PROCEEDS

We estimate the net proceeds from the sale of the notes, after deducting the underwriting discount and the estimated offering expenses, will
be $797 million. We intend to use the net proceeds from the sale of the notes for the repayment of short-term borrowings, which have an average annualized interest rate of approximately 4.55% and maturities under 30 days, and for general corporate
purposes.
