CBRE GROUP, INC. REPORTS STRONG FINANCIAL RESULTS FOR

FULL-YEAR AND FOURTH-QUARTER 2017

2017 Full Year Highlights

GAAP EPS of $2.03, up 20%

Adjusted EPS of $2.71, up 18%

8th Consecutive Year of Double-Digit Adjusted EPS Growth

Revenue and Fee Revenue up 9% and 8%, respectively

Los Angeles, CA – February 8, 2018 — CBRE Group, Inc. (NYSE:CBG) today reported strong financial results for the year and fourth quarter ended December 31, 2017.

“Our fourth-quarter results capped another excellent year for CBRE,” said Bob Sulentic, the company’s president and chief executive officer. “Fee revenue was up 9% in local currency and adjusted earnings per share rose 6%. Our performance significantly exceeded the expectations we discussed on our third quarter earnings call, and was led by occupier outsourcing and leasing fee revenue growth of 17% and 11% respectively, in local currency.”

“Revenue and earnings for 2017 reached all-time highs, and we made important strategic gains across the company,” he added. 2017 marked the 8^th consecutive year of double-digit adjusted earnings per share growth for CBRE.

Looking ahead to 2018, Mr. Sulentic said: “We regard the macro environment as a supportive backdrop for our business, and we continue to operate within an industry poised for long-term growth. This is due to the growing acceptance of outsourced commercial real estate services, the increasing capital allocation to commercial real estate as an institutional asset class, and the continuing consolidation of activity within our industry to the highest-quality, globally diversified market leaders.”

For full year 2018, CBRE expects to achieve adjusted earnings per share in the range of $3.00 to $3.15. This represents an increase of 13% at the midpoint of the range with 8% attributable to EBITDA growth and 5% attributable to the combined net effect of a lower expected tax rate due to U.S. corporate tax reform, interest savings and higher depreciation & amortization.

Note – CBRE has not reconciled the (non-GAAP) adjusted earnings per share forward-looking guidance included in this press release to the most directly comparable GAAP measure because this cannot be done without unreasonable effort due to the variability and low visibility with respect to costs related to acquisitions, carried interest incentive compensation and financing costs, which are potential adjustments to future earnings. We expect the variability of these items to have a potentially unpredictable, and a potentially significant, impact on our future GAAP financial results.

The terms “fee revenue,” “adjusted net income,” “adjusted earnings per share” (or adjusted EPS), “EBITDA” and “adjusted EBITDA,” all of which CBRE uses in this press release, are non-GAAP financial measures under SEC guidelines, and you should refer to the footnotes below as well as the “Non-GAAP Financial Measures” section in this press release for a further explanation of these measures. We have also included in that section reconciliations of these measures in specific periods to their most directly comparable financial measure calculated and presented in accordance with GAAP for those periods.

¹  Local currency percentage change is calculated by comparing current-period results at prior-period exchange rates versus prior-period results.

²  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. Certain adjustments have been made to 2016 fee revenue to conform with current-year presentation.

³  Adjusted net income and adjusted earnings per share (or adjusted EPS) exclude the effect of select charges from GAAP net income and GAAP earnings per diluted share as well as adjust the provision for income taxes for such charges. Adjustments during the periods presented included non-cash amortization expense related to certain intangible assets attributable to acquisitions, integration and other costs related to acquisitions, cost-elimination expenses and certain carried interest incentive compensation expense (reversal) to align with the timing of associated revenue. Adjustments also included the tax impact of U.S. tax reform.

⁴  In December 2017, the Securities and Exchange Commission (SEC) staff issued Staff Accounting Bulletin No. 118 (SAB 118), Income Tax Accounting Implications of the Tax Cuts and Jobs Act (Tax Act), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. The net charge related to the Tax Act is based upon our reasonable estimates and interpretation of the Tax Act. We consider certain aspects of this charge to be provisional and the impact may change due to additional guidance that may be issued by the U.S. Government as well as ongoing analysis of our data and assumptions we have made. Our accounting for the effects of the Tax Act is expected to be completed within the measurement period provided by SAB 118.

⁵  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

carried interest incentive compensation expense (reversal) to align with the timing of associated revenue, cash and non-cash charges related to acquisitions and certain cost-elimination expenses.

⁶  Revenue in the Development Services segment does not include equity income from unconsolidated subsidiaries and gain on disposition of real estate, net of non-controlling interest. EBITDA includes equity income from unconsolidated subsidiaries and gain on disposition of real estate, net of non-controlling interests, and the associated compensation expense.
