2029 Notes: On February 1, 2024, the Company issued $600,000 in aggregate principal amount of unsecured notes (the “2029 Notes”) and on December 3, 2024, the Company issued an additional $150,000 in aggregate principal amount of 2029 Notes under the same terms as the original issuance. As of June 30, 2025 and September 30, 2024, the outstanding aggregate principal amount of the 2029 Notes was $750,000 and $600,000, respectively. The 2029 Notes bear interest at a rate of 6.000% per year payable semi-annually in arrears on January 15 and July 15 of each year, commencing on July 15, 2024. The 2029 Notes mature on July 15, 2029.
The 2029 Notes are the Company’s general unsecured obligations that rank senior in right of payment to all of the Company’s future indebtedness or other obligations that are expressly subordinated, or junior, in right of payment to the 2029 Notes; equal in right of payment to the Company’s existing and future indebtedness or other obligations that are not so subordinated or junior; effectively junior to any of the Company’s secured indebtedness or other obligations (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness and other obligations (including trade payables) incurred by the Company’s subsidiaries, financing vehicles or similar facilities.
At any time or from time to time, the Company could redeem some or all of the 2029 Notes at a redemption price equal to the greater of (1) 100% of the principal amount of the 2029 Notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on the 2029 Notes on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 35 basis points less interest accrued to the date of redemption. If the Company redeems any 2029 Notes on or after June 15, 2029 (the date falling one month prior to the maturity date of the 2029 Notes), the redemption price for the 2029 Notes will be equal to 100% of the principal amount of the 2029 Notes to
be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the 2029 Notes.
On February 1, 2024 and December 3, 2024, the Company entered into interest rate swap agreements on the 2029 Notes with SMBC and Macquarie, respectively, as counterparties. Under the terms of the agreement with SMBC, the Company (i) receives a fixed rate of 6.248% and (ii) pays SMBC a rate of one-month Term SOFR + 2.444% on the first $600,000 of 2029 Notes. Under the terms of the agreement with Macquarie, the Company (i) receives a fixed rate of 5.881% and (ii) pays Macquarie a floating interest rate of three-month Term SOFR + 2.012% on the second $150,000 of the 2029 Notes. The Company designated these interest rate swap as effective hedge accounting instruments. The total notional amount of both swap agreements is $750,000 and both agreements terminate on June 15, 2029. The carrying value of the 2029 Notes is inclusive of an adjustment for the change in fair value of an effective hedge accounting relationship. See Note 5 for additional information.
