Excludes $1,055.0 million of warehouse facilities for loans originated on behalf of the FHA and other government sponsored enterprises outstanding at June 30, 2017, which are non-recourse to CBRE Group, Inc. Excludes non-recourse notes payable on real estate, net of unamortized debt issuance costs, of $18.2 million at June 30, 2017.

Slide 35

Non-GAAP financial measures The following measures are considered “non-GAAP financial measures” under SEC guidelines: fee revenue contractual fee revenue net income attributable to CBRE Group, Inc., as adjusted (which we also refer to as “adjusted net income”) 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”) EBITDA and adjusted EBITDA These measures are not recognized measurements under United States generally accepted accounting principles, or “GAAP.” 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 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. 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 Property Management business lines and our business generally. Fee revenue excludes costs reimbursable by clients, and as such provides greater visibility into the underlying performance of our business. With respect to contractual fee revenue: the company believes that investors may find this measure useful to analyze our overall financial performance because it identifies revenue streams that are typically more stable over time. With respect to adjusted net income, adjusted EPS, EBITDA and adjusted 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 these 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 adjusted 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 adjusted 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 adjusted 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 adjusted EBITDA and adjusted EPS as significant components when measuring our operating performance under our employee incentive compensation programs.

Slide 15 – The metrics included in the CBRE Cycle Radar are derived as follows: Cap Rate Spread – The capitalization rate on completed US office transactions per Real Capital Analytics less the yield on 10-year US Treasury Notes per FactSet. CRE Leverage – Total US outstanding commercial mortgages per the Board of Governors of the Federal Reserve System divided by nominal Gross Domestic Product for the US per the Bureau of Economic Analysis. Supply – Trailing 12-month US office real estate completions (in square feet) divided by the total stock of US office real estate square footage; per CBRE – Econometric Advisors. Rent Growth – Trailing 12-month US office rent growth per CBRE – Econometric Advisors. Occupancy – Total US office occupancy per CBRE – Econometric Advisors. REIT Valuation – Dividend yield on MSCI US REIT Index per FactSet less BofA Merrill Lynch US Corporate Bond BBB Effective Yield per FactSet. Stock Market Valuation – Earnings Yield on S&P 500 per FactSet less the yield on 10-year US Treasury Notes per FactSet. Yield Curve – Yield on 10-year US Treasury Notes per FactSet less the yield on 2-year US Treasury Notes per FactSet. Transaction Velocity – Total dollar value of US commercial real estate transactions per Real Capital Analytics divided by the Moody’s/RCA US National All-Property Composite Price Index per Real Capital Analytics. Slide 6 Leverage ratio is defined as year-end Net Debt divided by full-year Adjusted EBITDA. Net Debt is defined as total debt, net of unamortized debt premiums, discounts and issuance costs, excluding warehouse facilities for loans originated on behalf of FHA and other government sponsored entities which are non-recourse to CBRE Group, Inc., non-recourse notes payable on real estate, and net of cash, excluding cash in consolidated funds and other entities not available for company use at year-end. Adjusted EPS excludes the effect of select charges from GAAP EPS as well as adjusts the provision for income taxes for such charges. Adjustments during the periods presented included amortization expense related to certain intangible assets attributable to acquisitions, cost-elimination expenses, integration and other costs related to acquisitions, and certain carried interest incentive compensation (reversal) expense to align with the timing of associated revenue, write-off of financing costs on extinguished debt, goodwill and other non-amortizable intangible asset impairment, and the write-down of other impaired assets.

Slide 41

Footnotes Slide 33 CRE Debt defined as total US outstanding commercial mortgages per the Board of Governors of the Federal Reserve System. Slide 26 As of December 31 for each year presented except Q2 2017. In Process figures include Long-Term Operating Assets (LTOA) of $0.2 billion for Q2 2017, $0.2 billion for Q4 2016, $0.1 billion for Q4 2015, $0.3 billion for Q4 2014 and $0.9 billion for Q4 2013. LTOA are projects that have achieved a stabilized level of occupancy or have been held 18-24 months following shell completion or acquisition. Pipeline deals are those projects we are pursuing which we believe have a greater than 50% chance of closing or where land has been acquired and the projected construction start is more than twelve months out. Slide 28 Contractual revenue sources include revenue derived from our Occupier Outsourcing, Property Management, Investment Management, Valuation and Loan Servicing businesses. As noted above, we regard leasing revenue as largely recurring over time. Occupier Outsourcing and Property Management revenue excludes associated leasing and sales revenue, most of which is contractual.

As measured in dollar value loaned. Slide 23, 30, and 31 We regard leasing revenue as largely recurring over time because unlike most other transaction businesses, leasing activity normally takes place when leases expire. The average lease expires in five to six years. This means that, on average, in a typical year approximately 17% to 20% of leases roll over and a new leasing decision must be made. When a lease expires in the ordinary course, we expect it to be renewed, extended or the tenant to vacate the space to lease another space in the market. In each instance, a transaction is completed.  If there is a downturn in economic activity, some tenants may seek a short term lease extension, often a year, before making a longer term commitment. In this scenario, that delayed leasing activity tends to be stacked on top of the normal activity in the following year. Thus, we characterize leasing as largely recurring over time because we expect an expiration of a lease, in the ordinary course, to lead to an opportunity for a leasing commission from such completed transaction.
