CBRE GROUP, INC. REPORTS STRONG FINANCIAL RESULTS FOR

FIRST-QUARTER 2017

Revenue of $3.0 billion, up 5% (7% local currency)

Fee Revenue of $1.9 billion, up 5% (7% local currency)

GAAP EPS of $0.38, up 58%; Adjusted EPS of $0.43, up 19%

Los Angeles, CA – April 27, 2017 — CBRE Group, Inc. (NYSE:CBG) today reported strong financial results for the first quarter ended March 31, 2017.

“We have been keenly focused for some time on a strategy to make CBRE a more balanced and capable enterprise that produces highly differentiated outcomes for our clients,” said Bob Sulentic, CBRE’s president and chief executive officer. “In support of this strategy, we have made targeted organic investments and acquisitions aimed at bolstering our talent base, service offering and operating platform. These investments have allowed us to significantly improve our ability to provide integrated solutions to our clients around the world as well as our digital and consultative capabilities. All of this has positioned us to better satisfy our clients and take market share.

This was clearly evident in our first quarter results, with excellent top- and bottom-line organic growth across our regional services businesses globally. This growth came against a backdrop of lower sales market volumes in many parts of the world. Our earnings were further enhanced by the steps we took in late 2015 and 2016 to calibrate our costs while also investing in our strategy.”

First-Quarter 2017 Segment Review

The following tables present highlights of CBRE segment performance during the first quarter of 2017 (dollars in thousands):

CBRE exhibited broad strength across its regional services businesses in the first quarter of 2017.

In the United Kingdom, overall revenue rose 8% in local currency, with solid growth across virtually all business lines. Growth of 9% in leasing and 5% in sales (both in local currency) reflected continued improvement in market sentiment following the European Union referendum (Brexit) vote and market share gains for CBRE.

Revenue growth was also solid across most global business lines and was almost entirely organic.

CBRE completed two acquisitions during the quarter – Floored, Inc., a leading Software as a Service (SaaS) platform for commercial real estate, and Capstone Financial Solutions LLC, a technology-enabled national commercial mortgage services specialist. Earlier this month, the company acquired Mainstream Software, Inc., a leading SaaS platform for facilities management.

Business Outlook

“We are pleased with the excellent performance our people produced in the first quarter. As we look ahead, we are increasingly energized by our market position and prospects,” Mr. Sulentic said. “Our business has positive momentum and our people – supported by our increasingly robust operating platform – are well positioned to capitalize on a generally favorable macro environment. At the same time, it is important to remember that the first quarter is typically our seasonally lightest quarter for revenue and earnings, and the impact of our cost savings actions is particularly pronounced this quarter. As always, we caution against extrapolating first quarter performance to the full year and we are not updating guidance only three months into the year.”

Additional information concerning factors that may influence the company’s financial information is discussed under “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Quantitative and Qualitative Disclosures About Market Risk” and “Cautionary Note on Forward-Looking Statements” in our Annual Report on Form 10-K for the year ended December 31, 2016, as well as in the company’s press releases and other periodic filings with the Securities and Exchange Commission (SEC). Such filings are available publicly and may be obtained on the company’s website at www.cbre.com or upon written request from CBRE’s Investor Relations Department at investorrelations@cbre.com.

Note – CBRE has not reconciled the (non-GAAP) adjusted earnings per share forward-looking guidance referenced in this 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, financing costs and future tax rates, 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,” “organic 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.

Non-GAAP Financial Measures

The following measures are considered “non-GAAP financial measures” under SEC guidelines:

These measures are not recognized measurements under United States generally accepted accounting principles, or “GAAP.” When analyzing our operating performance, investors 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 and organic fee revenue: the company believes that investors may find these measures 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. Organic fee revenue further excludes contributions from all acquisitions completed after first-quarter 2016.

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 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 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.
