Item 1.01 Entry into a Material Definitive Agreement.

364-Day Revolving Credit Agreement

On June 23, 2026, the Company entered into a new 364-day senior unsecured Revolving Credit Agreement (the "364-Day Revolving Credit Agreement"), by and among the Company, CBRE Services, Inc., a Delaware corporation ("Services"), the lenders party thereto and Wells Fargo Bank, National Association ("Wells Fargo"), as administrative agent for the lenders. The 364-Day Revolving Credit Agreement provides for a senior unsecured revolving credit facility available to Services with commitments in an aggregate principal amount of up to $1 billion. The 364-Day Revolving Credit Agreement replaces the Company's previous 364-day senior unsecured Revolving Credit Agreement, dated as of June 24, 2025, which was scheduled to terminate on June 23, 2026.

Interest Rate and Fees

The 364-Day Revolving Credit Agreement provides that loans will bear interest at (i) a rate equal to an applicable rate (as described below), plus, (ii) at Services' option, either (a) a Term SOFR rate published by CME Group Benchmark Administration Limited for the applicable interest period or (b) a base rate determined by reference to the greatest of (1) the prime rate determined by Wells Fargo, (2) the federal funds rate plus 1/2 of 1% and (3) the sum of (x) a Term SOFR rate published by CME Group Benchmark Administration Limited for an interest period of one month and (y) 1.00%.

The applicable rate for borrowings under the 364-Day Revolving Credit Agreement will generally bear interest at an annual rate equal to Term SOFR plus between 0.645% and 1.125%, depending on the Company's credit rating.

The base rate spread for borrowings under the 364-Day Revolving Credit Agreement will generally bear interest at a rate between 0% and 0.10%, depending on the Company's credit rating. In addition to paying interest on outstanding principal under the 364-Day Revolving Credit Agreement, Services is required to pay a facility fee of between 0.055% and 0.125% to the lenders under the 364-Day Revolving Credit Agreement (whether drawn or undrawn), which facility fee is based on the Company's credit rating.

Prepayments

The 364-Day Revolving Credit Agreement does not require Services to prepay revolving loans under the 364-Day Revolving Credit Agreement ("364-Day Revolving Credit Loans"), except on any date on which the sum of all outstanding 364-Day Revolving Credit Loans exceed the Revolving Credit Commitment under the 364-Day Revolving Credit Agreement, in which case Services must pay 100% of such excess amount.

Services may voluntarily repay 364-Day Revolving Credit Loans at any time, in whole or in part, without premium or penalty (other than customary "breakage" costs). In addition, Services may elect to permanently terminate or reduce all or a portion of the Revolving Credit Commitments under the 364-Day Revolving Credit Agreement, in each case, without premium or penalty.

Maturity

The entire principal amount of the 364-Day Revolving Credit Loans (if any) is due and payable in full at maturity on June 22, 2027, on which day the Revolving Credit Commitments under the 364-Day Revolving Credit Agreement will terminate.

Guarantee

All obligations under the 364-Day Revolving Credit Agreement are guaranteed by the Company, Services (solely with respect to certain guaranteed subsidiary cash management and hedging obligations) and each of the Company's

direct and indirect U.S. wholly-owned subsidiaries which guarantee any other material indebtedness of the Company and its subsidiaries. As of the date hereof, no such subsidiaries guarantee the 364-Day Revolving Credit Agreement or any other material indebtedness of the Company and its subsidiaries.

Covenants and Events of Default

The 364-Day Revolving Credit Agreement includes a financial covenant requiring the Company and its subsidiaries to maintain a specified maximum leverage ratio on the last day of each fiscal quarter. In addition, the 364-Day Revolving Credit Agreement also contains other customary affirmative and negative covenants and events of default.
