Non-Gaap financial measures The following measures are considered “non-GAAP financial measures” under SEC guidelines: (i) Fee revenue (ii) Net income attributable to CBRE Group, Inc., as adjusted (which we also refer to as “adjusted net income”) (iii) Diluted income per share attributable to CBRE Group, Inc. shareholders, as adjusted (which we also refer to as “adjusted earnings per share” or “adjusted EPS”) (iv) EBITDA and EBITDA, as adjusted (the latter of which we also refer to as “Normalized EBITDA”) None of these measures is a recognized measurement under U.S. generally accepted accounting principles, or U.S. GAAP, and when analyzing our operating performance, readers should use them in addition to, and not as an alternative for, their most directly comparable financial measure calculated and presented in accordance with U.S. GAAP. Because not all companies use identical calculations, our presentation of these measures may not be comparable to similarly titled measures of other companies. Our management generally uses these non-GAAP financial measures to evaluate operating performance and for other discretionary purposes, and the Company believes that these measures provide a more complete understanding of ongoing operations, enhance comparability of current results to prior periods and may be useful for investors to analyze our financial performance because they eliminate the impact of selected charges that may obscure trends in the underlying performance of our business. The Company further uses certain of these measures, and believes that they are useful to investors, for purposes described below. With respect to fee revenue: The Company believes that investors may find this measure useful to analyze the financial performance of our Occupier Outsourcing and Asset Services business lines and our business generally because it excludes costs reimbursable by clients and as such provides greater visibility into the underlying performance of our business. With respect to adjusted net income, adjusted EPS, EBITDA and Normalized EBITDA: The Company believes that investors may find these measures useful in evaluating our operating performance compared to that of other companies in our industry because their calculations generally eliminate the accounting effects of acquisitions, which would include impairment charges of goodwill and intangibles created from acquisitions, and—in the case of EBITDA and Normalized EBITDA—the effects of financings and income tax and the accounting effects of capital spending. All of these measures may vary for different companies for reasons unrelated to overall operating performance. In the case of EBITDA and Normalized EBITDA, these measures are not intended to be measures of free cash flow for our management’s discretionary use because they do not consider cash requirements such as tax and debt service payments. The EBITDA and Normalized EBITDA measures calculated herein may also differ from the amounts calculated under similarly titled definitions in our credit facilities and debt instruments, which amounts are further adjusted to reflect certain other cash and non-cash charges and are used by us to determine compliance with financial covenants therein and our ability to engage in certain activities, such as incurring additional debt and making certain restricted payments. The Company also uses Normalized EBITDA and adjusted EPS as significant components when measuring our operating performance under our employee incentive compensation programs.

This expense has only been normalized for funds that incurred carried interest expense for the first time in Q2 2013 or in subsequent quarters.

Reconciliation of gross revenue to fee revenue Twelve Months Ended December 31, ($ in millions) 2014 Pro-forma 1,2 2006 Consolidated revenue $ 12,457 $ 4,032 Less: Client reimbursed costs largely associated with employees dedicated to client facilities and subcontracted vendor work performed for clients 4,031 1,378 Consolidated fee revenue $ 8,426 $ 3,742 2014 pro-forma revenue includes revenue of the acquired GWS business representing the trailing twelve months as of December 31, 2014 and CBRE gross revenue for the year ended December 31, 2014. 2014 pro-forma fee revenue is defined as fee revenue for CBRE and the acquired GWS business on a combined basis for the year ended December 31, 2014.

Footnotes Slide 11 Note: Combined total fee revenue for 2014 has been adjusted downward from what was last presented in September 2015 for approximately $300 million of additional client-reimbursed sub-contracted vendor costs within the acquired Global Workplace Solutions business. Other includes Development Services (1% in both 2006 and 2014 combined) and Other (1% in both 2006 and 2014 combined). “Combined” means CBRE and the acquired GWS business on a combined basis for the year ended December 31, 2014. Capital Markets includes Sales (33% in 2006 and 18% in 2014 combined) and Commercial Mortgage Services (4% in both 2006 and 2014 combined). Contractual Revenues include Occupier Outsourcing and Asset Services (7% in 2006 and 36% in 2014 combined; excludes associated sales and lease revenues, most of which are contractual), Global Investment Management (6% in both 2006 and 2014 combined), and Valuation (8% in 2006 and 6% in 2014 combined). “Combined total fee revenue” is defined as fee revenue for CBRE and GWS combined for the year ended December 31, 2014. Fee Revenue is gross revenue less client reimbursed costs largely associated with our employees that are dedicated to client facilities and subcontracted vendor work performed for clients. Contractual plus leasing revenues are 64% of 2006 GAAP revenue and 84% of 2014 combined calendar year GAAP revenue. Slide 3 We have not reconciled the non-GAAP EPS guidance to the most directly comparable GAAP measure because this cannot be done without unreasonable effort. Slide 5 Note: Local currency percent changes versus prior year is a non-GAAP financial measure. These percent changes are calculated by comparing current year results versus prior year results, in each case at prior year exchange rates. Normalized EBITDA excludes cost containment expenses, integration and other costs related to acquisitions and certain carried interest expense (to better match with carried interest revenue realization). Adjusted EPS includes the impact of adjusting provision for income taxes to a normalized rate and excludes amortization expense related to certain intangible assets attributable to acquisitions (net of tax), integration and other costs related to acquisitions (net of tax), certain carried interest incentive compensation expense (net of tax) and the write-off of financing costs (net of tax). Slide 10 The base purchase price was $1.475 billion in cash plus approximately $36 million in estimated net adjustments for working capital and other items. Such net adjustments took into account approximately $45 million in cash acquired by CBRE in the acquisition. The purchase price is subject to post-closing adjustments as outlined in the purchase agreement for the transaction. Deal costs are excluded from the purchase price. Multiple based on GWS adjusted EBITDA as calculated by GWS (when owned by Johnson Controls) and using GWS’s methodologies (when owned by Johnson Controls).
