Non-GAAP Financial Measures The following measures are considered “non-GAAP financial measures” under SEC guidelines: fee revenue contractual fee revenue adjusted revenue for the Real Estate Investments segment 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 Global Workplace Solutions segment and Property & Advisory Project Management business line 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 adjusted revenue: the company believes that investors may find this measure useful to analyze the financial performance of our Real Estate Investments segment because it is more reflective of this segment’s total operations. 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 and adjusted revenue 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.

Debt & Leverage Excludes $107.0 million, $155.2 million and $94.6 million of cash in consolidated funds and other entities not available for company use at March 31, 2019, December 31, 2018 and December 31, 2012, respectively. Outstanding amount is reflected net of unamortized debt issuance costs. Excludes $1,561.2 million, $1,328.8 million and $1,026.4 million of warehouse facilities for loans originated on behalf of the FHA and other government sponsored enterprises outstanding at March 31, 2019, December 31, 2018 and December 31, 2012, respectively, which are non-recourse to CBRE Group, Inc. Excludes non-recourse notes payable on real estate, net of unamortized debt issuance costs, of $6.3 million at March 31, 2019 and December 31, 2018 and $312.1 million at December 31, 2012. Total net debt is calculated as total debt (excluding non-recourse debt) less cash available for company use, as disclosed above. Adjusted EBITDA excludes (from EBITDA) the impact of a one-time non-cash gain associated with remeasuring CBRE’s investment in an unconsolidated subsidiary in New England to fair value as of the date it acquired the remaining controlling interest, costs associated with our reorganization, including cost-savings initiatives, costs incurred in connection with a litigation settlement, integration and other costs related to acquisitions, cost-elimination expenses and certain carried interest incentive compensation expense to align with the timing of associated revenue. Note: March 31, 2019 and December 31, 2018 TTM adjusted EBITDA reflect ASC 606. We have not made a similar restatement for 2012, and 2012 TTM adjusted EBITDA continues to be reported under the accounting standards in effect for that period.

Contractual fee revenue now refers to fee revenue derived from our GWS business (excluding leasing), Property & Advisory Project Management business, contractual REI revenue as well as from our valuation and loan servicing businesses.

Footnotes NOTES: Local currency percent changes versus prior year are non-GAAP financial measures noted on slide 38. These percent changes are calculated by comparing current year results versus prior year results, in each case at prior year exchange rates. In the first quarter of 2018, the company adopted new revenue recognition guidance. Restatements have been made to 2017 and 2016 financial data included in this presentation on slides 15, 16, 45 and 46 to conform with the 2018 presentation. Financial data for periods prior to 2016 have not been restated and continue to be reported under the accounting standards in effect for the relevant period. Accordingly, such prior period amounts should not be compared with the restated financial data for 2016, 2017 and 2018. Although we believe that any prior period amounts would not be significantly different if we had restated such periods to conform with the 2018 presentation, there can be no assurance that there would not be a difference, and any such difference may be material.  Slide 3 Property and corporate facilities under management as of December 31, 2018, includes square footage managed by affiliates.

Slide 15 Adjusted net income excludes a one-time non-cash gain associated with remeasuring CBRE’s investment in an unconsolidated subsidiary in New England to fair value as of the date it acquired the remaining controlling interest, depreciation and amortization related to certain assets attributable to acquisitions, integration and other costs related to acquisitions, costs associated with our reorganization, including cost-savings initiatives, costs incurred in connection with a litigation settlement, write-off of financing costs on extinguished debt, cost-elimination expenses, and certain carried interest incentive compensation (reversal) expense to align with timing of associated revenue as well as adjusts the provision for income taxes for such items. Adjusted net income also excludes the tax impact of U.S. tax reform initially recorded in the fourth quarter of 2017 and finalized during 2018.

Footnotes Slide 16 Adjusted EPS excludes a one-time non-cash gain associated with remeasuring CBRE’s investment in an unconsolidated subsidiary in New England to fair value as of the date it acquired the remaining controlling interest, depreciation and amortization expense related to certain assets attributable to acquisitions, integration and other costs related to acquisitions, costs associated with our reorganization, including cost-savings initiatives, costs incurred in connection with a litigation settlement, write-off of financing costs on extinguished debt, cost-elimination expenses, goodwill and other non-amortizable intangible asset impairment and certain carried interest incentive compensation (reversal) expense to align with the timing of associated revenue as well as adjusts the provision for income taxes for such items. Adjusted EPS also excludes the tax impact of U.S. tax reform initially recorded in the fourth quarter of 2017 and finalized during 2018. All EPS information is based on diluted shares. 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. Slide 18 Fee revenue is gross revenue less both client reimbursed costs largely associated with employees that are dedicated to client facilities and subcontracted vendor work performed for clients. EBITDA represents earnings before net interest expense, write-off of financing costs on extinguished debt, income taxes, depreciation and amortization. Amounts shown for adjusted EBITDA further remove (from EBITDA) the impact of certain cash and non-cash items related to acquisitions, costs associated with our reorganization, including cost-savings initiatives, certain carried interest incentive compensation reversal to align with the timing of associated revenue and other non-recurring costs.   Revenue and fee revenue are the same amount for REI as this segment does not have client reimbursed costs. Adjusted fee revenue is Real Estate Investments fee revenue plus equity income from unconsolidated subsidiaries and gain on disposition of real estate, net of non-controlling interest. We believe that investors may find this measure useful to analyze the financial performance of our Real Estate Investments segment because it is more reflective of its total operations.

Slide 33 As of March 31, 2019. AUM refers to the fair market value of real asset-related investments with respect to which CBRE Global Investors provides, on a global basis, oversight, investment management services and other advice and which generally consist of investments in real assets; equity in funds and joint ventures; securities portfolios; operating companies and real asset-related loans. This AUM is intended principally to reflect the extent of CBRE Global Investors’ presence in the global real asset market, and its calculation of AUM may differ from the calculations of other investment or asset managers. As of March 31, 2019, in process figures include Long-Term Operating Assets (LTOA) of $30M for Q1 2019. LTOA are projects that have achieved a stabilized level of occupancy or have been held 18-24 months following shell completion or acquisition. Slide 34 As of March 31, 2019. AUM refers to the fair market value of real asset-related investments with respect to which CBRE Global Investors provides, on a global basis, oversight, investment management services and other advice and which generally consist of investments in real assets; equity in funds and joint ventures; securities portfolios; operating companies and real asset-related loans. This AUM is intended principally to reflect the extent of CBRE Global Investors’ presence in the global real asset market, and its calculation of AUM may differ from the calculations of other investment or asset managers. As of March 31, 2019. Investment by Region refers to the regional mandate and/or the location of the underlying investment. AUM by investment type refers to the allocation of assets across the four primary segments: Private Real Estate, Securities, Private Infrastructure and Other. AUM by Strategy refers to the allocation of assets among strategies. Core / Core Plus generally refers to investment strategies that include stabilized investments, with a moderate return and leverage profile. Enhanced Return generally refers to value-add and opportunistic investment strategies with a higher return and leverage profile. Allocation figures are subject to change and may not sum due to rounding. Slide 35 In process as of March 31, 2019. In process figures include Long-Term Operating Assets (LTOA) of $30M for Q1 2019, $30M for Q4 2018, $151M for Q4 2017, $152M for Q4 2016, $152M for Q4 2015, $273M for Q4 2014 and $851M 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 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 12 months out. Slide 38 Contractual revenue refers to revenue derived from our Global Workplace Solutions, Advisory Property & Project Management, Valuation, REI (excl. carried interest) and Loan Servicing businesses. 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 even if delayed by a year or two during an economic downturn. Fee revenue is gross revenue less both client reimbursed costs largely associated with employees that are dedicated to client facilities and subcontracted vendor work performed for clients.
