At any time prior to April 15, 2027, the Issuer may redeem the 2030 Notes in whole at any time, or in part from time to time, at its option, at a redemption price equal to 100% of the principal amount of the 2030 Notes redeemed plus the Applicable Premium (as defined below) as of, and accrued and unpaid interest, if any, to but not including the redemption date.
“Applicable Premium” means, with respect to any 2030 Notes on any redemption date, the greater of: (1) 1.0% of the principal amount of such note; and (2) the excess, if any, of (a) the present value at such redemption date of (i) the redemption price of such note at April 15, 2027 (such redemption price being set forth in the table appearing above), plus (ii) all required interest payments due on such note through April 15, 2027 (excluding accrued but unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over (b) the principal amount of such note.


“Treasury Rate” means, with respect to the 2030 Notes, as of the date of the relevant redemption notice, the weekly average rounded to the nearest 1/100th of a percentage point (for the most recently completed week for which such information is available as of the date that is two business days prior to the date of such redemption notice) of the yield to maturity of United States Treasury securities with a constant maturity (as compiled and published in Federal Reserve Statistical Release H.15 with respect to each applicable day during such week or, if such Statistical Release is no longer published or the relevant information is no longer available thereon, any publicly available source of similar market data) most nearly equal to the period from the date of such redemption notice to April 15, 2027; provided, however, that if the period from the date of such redemption notice to April 15, 2027 is not equal to the constant maturity of a United States Treasury security for which such a yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the redemption date to April 15, 2027 is less than one year, the weekly average yield on actively traded United States Treasury securities adjusted to a constant maturity of one year shall be used. Any such Treasury Rate shall be determined, and the information required to be obtained for its calculation shall be obtained, by the Issuer.

Prior to April 15, 2027, the Issuer may, at its option, on one or more occasions, redeem up to 40% of the aggregate principal amount of 2030 Notes at a redemption price equal to 106.500% of the aggregate principal amount thereof, plus accrued and unpaid interest thereon, if any, to but not including the applicable redemption date, with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided that at least 50% of the 2030 Notes originally issued under the indenture remains outstanding immediately after the occurrence of each such redemption; and provided, further, that each such redemption occurs within 180 days of the date of closing of each such Equity Offering.
“Equity Offering” means a public or private sale of Equity Interests of the Issuer or the Parent Guarantor made for cash, or any cash contribution to the equity capital of the Issuer, in each case made after the Issue Date.

Trade Date:March 6, 2025
Settlement Date:
March 14, 2025 (T+6)
We expect that delivery of the Notes will be made to investors on or about March 14, 2025, which will be the sixth Business Day following the date of pricing of the Notes (such settlement being referred to as T+6). Under Rule 15c6- 1 under the Securities Exchange Act of 1934, trades in the secondary market are required to settle in one Business Day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes prior to one Business Day before their delivery will be required, by virtue of the fact that the Notes initially settle in T+6, to specify an alternative settlement arrangement at the time of any such trade to prevent a failed settlement.
Purchasers of the Notes who wish to trade the Notes prior to one Business Day before their delivery should consult their advisors.
Distribution:SEC Registered Offering
Net Proceeds:
We estimate that the net proceeds from this offering of the Notes will be approximately $1,782,000,000 after deducting the underwriting discount and before deducting other estimated fees and expenses of this offering.
Denominations:$2,000 and integral multiples of $1,000 in excess thereof
