FOR IMMEDIATE RELEASE

CBRE GROUP, INC. REPORTS STRONG FINANCIAL RESULTS FOR

FIRST-QUARTER 2018

GAAP EPS of $0.44, up 10%

Adjusted EPS of $0.54, up 20%

Revenue and Fee Revenue up 15% and 18%, respectively

Los Angeles, CA – May 2, 2018 — CBRE Group, Inc. (NYSE:CBRE) today reported strong financial results for the first quarter ended March 31, 2018.

“CBRE had an excellent start to 2018 with double-digit growth in revenue and a 20% increase in adjusted earnings per share,” said Bob Sulentic, CBRE’s president and chief executive officer. “Our performance for the quarter – paced by growth in global occupier outsourcing, capital markets and our Asia Pacific business – results from the execution of our strategy, which is centered on delivering differentiated client outcomes around the world, as well as the attractiveness of our sector.”

“While we caution against extrapolating first quarter results, we are tracking slightly ahead of our full-year 2018 guidance. First quarter results were ahead of our expectations across revenue, margins, and earnings and we continue to see solid momentum in our business. The first quarter is seasonally our slowest of the year and we will provide further commentary next quarter,” he continued.

Mr. Sulentic concluded: “CBRE continues to benefit from the strong secular trends that support our industry. These trends include growing occupier appetite for outsourced real estate services, increasing institutional capital allocation to the commercial real estate asset class, and the continued consolidation in our sector around the leading globally capable service providers.”

“Our strategy is aimed squarely at making the most of these macro trends, and we are sustaining progress on many fronts – from digital technology investments to Client Care initiatives to enhancing our talent base and better connecting our people around the world.  The successful execution of our strategy will ensure that we continue to produce outcomes for our clients that others find difficult to replicate.”

First-Quarter 2018 Segment and Business Line Review¹

The following tables present highlights of CBRE segment performance during the first quarter of 2018 (dollars in thousands):

CBRE produced strong revenue growth in its three global regions in the first quarter. APAC (Asia Pacific) saw revenue increase 23% (17% local currency) with outsized growth in India and Japan. EMEA (Europe, the Middle East & Africa) revenue also increased strongly, rising 31% (16% local currency), driven by France, Italy, the Netherlands and the United Kingdom. Americas revenue was up 8% (same local currency), supported by growth in Canada, Mexico and the United States.

Global occupier outsourcing once again achieved robust revenue growth, as the secular outsourcing trend continued to be a powerful growth catalyst. Revenue increased 16% (12% local currency) and fee revenue rose 26% (18% local currency). Growth was strong across geographies, notably in India, the United States and several continental European countries. Acquisitions contributed 2% (same local currency) to the revenue growth rate and 5% (same local currency) to the fee revenue growth rate in the current quarter.

CBRE’s capital markets businesses – property sales and commercial mortgage origination – achieved combined revenue growth of 17% (14% local currency).

Global property sales revenue rose 15% (11% local currency), as CBRE continued to gain market share. Americas sales revenue rose 14% (same local currency), with double-digit growth in Canada and the United States. APAC sales revenue increased 14% (8% local currency), driven largely by Japan and EMEA sales revenue rose 16% (3% local currency), led by Germany. This growth followed a 16% (local currency) increase in EMEA sales revenue in the first quarter of 2017.

For the first quarter, CBRE’s U.S. investment sales market share rose more than 100 basis points to 14.9%, according to Real Capital Analytics (RCA).

Commercial mortgage origination revenue increased 27% (26% local currency), reflecting brisk growth with both government agencies and private sector lenders.

Strong mortgage origination activity supported the continued growth of the $184 billion loan servicing portfolio, which increased 23% from the first quarter of 2017. Recurring revenue from loan servicing increased 15% (14% local currency).

Leasing revenue rose 8% (5% local currency), with notable strength in international markets. EMEA and APAC achieved growth of 34% (19% local currency) and 18% (13% local currency), respectively. France, India and the United Kingdom were standouts during the quarter. Americas leasing revenue edged up 2% (1% local currency).

Property management services produced revenue and fee revenue growth of 11% (7% local currency) and 18% (13% local currency), respectively. Fee revenue rose by double digits in all three global regions and was supported in part by the continued strong growth in the investment fund administration business.

Valuation revenue rose 8% (3% local currency), paced by EMEA.

Adjusted EBITDA for CBRE’s real estate investment businesses rose significantly, increasing $21.9 million on a combined basis. Growth was driven by large asset sales in Development Services (which were reported in equity income from unconsolidated subsidiaries) and higher carried interest in Global Investment Management.

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.

¹  In the first quarter of 2018, we adopted new revenue recognition guidance. Certain restatements have been made to the 2017 financial statements to conform with the 2018 presentation.

²  Local currency percentage change is calculated by comparing current-period results at prior-period exchange rates versus prior-period results.

³  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. Organic fee revenue further excludes contributions from all acquisitions completed after first-quarter 2017.

⁴  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, write-off of financing costs on extinguished debt and certain carried interest incentive compensation reversals to align with the timing of associated revenue. Adjustments also included an update to the provisional estimated tax impact of U.S. tax reform initially recorded in the fourth quarter of 2017.

⁵  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 in the first quarter of 2018 related to an update of the net provision associated with the Tax Act 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.

⁶  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 reversals to align with the timing of associated revenue and cash and non-cash charges related to acquisitions.

⁷  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.

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 2017.

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.
