Indenture

On July 22, 2025, AECOM (the “Company”) completed an offering of $1,200,000,000 aggregate principal amount of its 6.000% Senior Notes due 2033 (the “Notes”). The Notes were sold in the United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States to non-U.S. persons pursuant to Regulation S under the Securities Act.

The Notes were issued pursuant to an indenture, dated as of July 22, 2025 (the “Indenture”), by and among the Company, certain subsidiaries of the Company party thereto and U.S. Bank Trust Company, National Association, as trustee. The Company used $752,585,310 of the net proceeds of the offering of the Notes to purchase $732,914,000 in principal amount of the Company’s 5.125% Senior Notes due 2027 (the “2027 Notes”) that were validly tendered and not validly withdrawn at or prior to the July 21, 2025 expiration date of its previously announced tender offer for the 2027 Notes, and intends to use the remaining net proceeds to (i) purchase on July 24, 2025 any 2027 Notes for which a properly completed and duly executed notice of guaranteed delivery was delivered at or prior to the tender offer expiration date, (ii) redeem on August 14, 2025 any 2027 Notes not tendered in the tender offer, and (iii) pay related fees and expenses and for general corporate purposes.

Interest will be payable on the Notes at a rate of 6.000% per annum. Interest on the Notes will be payable semi-annually on February 1 and August 1 of each year, commencing on February 1, 2026. The Notes will mature on August 1, 2033.

At any time and from time to time prior to August 1, 2028, the Company may redeem all or part of the Notes, at a redemption price equal to 100% of their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest to, but excluding, the redemption date. In addition, at any time and from time to time prior to August 1, 2028, the Company may redeem up to 40% of the aggregate principal amount of the Notes with the proceeds of one or more qualified equity offerings, at a redemption price equal to 106.000%, plus accrued and unpaid interest to, but excluding, the redemption date. Furthermore, at any time on or after August 1, 2028, the Company may redeem on one or more occasions all or part of the Notes at the redemption prices set forth below, plus accrued and unpaid interest thereon to, but excluding, the redemption date, if redeemed during the 12-month period beginning on August 1 of each of the years indicated below:

Year	Percentage
2028		103.000	%
2029		101.500	%
2030 and thereafter		100.000	%

The Notes are guaranteed on a senior unsecured basis by the Company’s existing and future domestic restricted subsidiaries that guarantee the indebtedness under the Company’s credit agreement and certain other indebtedness.

The Indenture contains customary events of default, including, among other things, payment default, failure to provide certain notices thereunder and certain provisions related to bankruptcy events. The Indenture also contains customary negative covenants.
