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amount of the Company’s 5.125% Senior Notes due 2027 (the “2027 Notes”) that were validly tendered and not validly withdrawn at or prior to the July 21, 2025 expiration date of its previously announced tender offer for the 2027 Notes, and intends to use the remaining net proceeds to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.
