See slide 14 for footnotes.

Expected run-rate cost synergies increased to $50 million from $35 million Approximately $30 million expected to be realized in 2016 Remaining run-rate savings largely expected by year-end 2017 Still expect acquisition to be materially accretive to 2016 adjusted EPS Now expect high-single-digit rather than mid-single-digit percentage accretion Expect acquired business to contribute $0.03 to $0.04 to 2015 adjusted EPS. Calendar-year Q4 is typically a seasonally slower quarter for the acquired Global Workplace Solutions business due to its previous fiscal year ending on September 30th As a result, the accretion for the last four months of 2015 is not indicative of the expected higher run-rate in 2016.

Supplemental slides and GAAP Reconciliation tables

Footnotes Slide 5 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. Normalized EBITDA excludes (from EBITDA) certain carried interest incentive compensation expense and integration and other costs related to acquisitions. Fee revenue margin is based on Normalized EBITDA. Adjusted net income and adjusted EPS include the impact of adjusting provision for income taxes to a normalized rate as well as exclude amortization expense related to certain intangible assets attributable to acquisitions, the write-off of financing costs, integration and other costs related to acquisitions, and adjusts the timing of certain carried interest incentive compensation expense to match the timing of such expense with related revenue. All EPS information is based on diluted shares. Based on adjusted results. Also excludes net impact of mark-to-market hedges, and exchange rate transaction impact. Slide 10 Excludes securities business. Normalized EBITDA excludes (from EBITDA) certain carried interest compensation expense. As of September 30, 2015. Slide 11 In Process figures include Long-Term Operating Assets (LTOA) of $0.1 billion for Q3 15, $0.3 billion for 4Q 14, $0.9 billion for 4Q 13, $1.2 billion for 4Q 12, $1.5 billion for 4Q 11, $1.6 billion for 4Q 10, and $1.4 billion for 4Q 09. 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 12 months out. Pro-forma revenue is revenue plus equity in unconsolidated subsidiaries and gains on sales of assets net of non-controlling interest. Note – Local currency percent changes versus prior year is a non-GAAP measure noted on slides 5, 7 and 8. These percent changes are calculated by comparing current year results at prior year exchange rates versus prior year results. In addition, we have not reconciled the (non-GAAP) adjusted earnings per share guidance included in this release to the most directly comparable GAAP measure because this cannot be done without unreasonable effort.

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.
