FOR IMMEDIATE RELEASE

CBRE GROUP, INC. REPORTS DOUBLE-DIGIT

THIRD-QUARTER 2018 REVENUE AND EARNINGS GROWTH

GAAP EPS up 47% to $0.85

Adjusted EPS up 22% to $0.79

Revenue up 13% (15% local currency)

Fee Revenue up 13% (14% local currency)

Los Angeles, CA – November 1, 2018 — CBRE Group, Inc. (NYSE:CBRE) today reported strong financial results for the third quarter ended September 30, 2018.

“We continue to deliver double-digit increases on the top- and bottom-lines,” said Bob Sulentic, president and chief executive officer of CBRE. “Our strong growth this quarter was driven by gains across major parts of our business – notably, global leasing, occupier outsourcing, mortgage origination and development services.

We also continued to make significant strategic gains. The reorganization we are planning will give CBRE an enhanced focus on our business line capabilities around the world and greater operational and cost efficiency. Our  new Hana flexible space solutions initiative allows us to deliver a service that is in strong and rapidly increasing demand. This service evolved from a tremendous amount of interaction with – and encouragement from – our clients. Our deep relationships with property investors and occupiers, and what we have learned from our workplace experience service, CBRE 360, position us well to succeed with this new offering.”

Looking ahead, Mr. Sulentic said: “While investors have clearly been concerned about the effects of higher interest rates and trade tensions, commercial real estate fundamentals have been resilient in the face of higher rates, and escalating trade tensions do not appear to be impacting our overall business. However, continued escalation could impact business sentiment, most notably for select markets in Asia, which, combined, typically represent approximately 2% of our adjusted EBITDA.”

Given its strong performance year-to-date and a favorable business outlook, CBRE anticipates full-year 2018 adjusted earnings-per-share coming in at the high end of its guidance, which was increased last quarter to a range of $3.10 to $3.20.

Third-Quarter 2018 Segment and Business Line Review

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

Revenue growth in the combined regional services business remained strong, particularly in the Americas and EMEA (Europe, the Middle East & Africa). In EMEA, revenue rose 22% (23% local currency), with notable growth in Germany, Italy, Spain and the United Kingdom. Americas revenue increased 12% (same local currency), paced by a 14% gain in the United States. APAC (Asia Pacific) revenue climbed 6% (9% local currency), led by Greater China, India and Singapore.

For the combined regional services business, fee revenue rose 13% (14% local currency) and adjusted EBITDA increased 6% (7% local currency). Adjusted EBITDA margin on fee revenue for the combined

regional services business declined one percentage point versus the third quarter of 2017 to 15.0%. The majority of the decline was driven by incremental investments which the company outlined at the beginning of the year and is consistent with its guidance. Adjusted EBITDA margins on fee revenue for the regional services business would have been approximately 40 basis points higher absent the impact of all foreign currency effects and the acquisition of lower margin, but typically high-growth outsourcing businesses. The company continues to expect positive operating leverage in its combined regional services business in 2019.

The leasing business paced revenue growth with a 17% (18% local currency) gain, as all three global regions produced double-digit increases. The Americas led the way with an 18% (19% local currency) increase (15% organic growth), with strong performance across the region. EMEA was also very strong, with France and the United Kingdom driving a 17% (18% local currency) gain for the region. APAC rose 12% (16% local currency), led by Australia, Greater China and India.

Occupier outsourcing revenue rose by double-digits globally, as CBRE continued to capture a significant share of the growing trend toward outsourcing real estate and facilities services. On a global basis, both revenue and fee revenue increased 15% (16% local currency), with all three regions producing mid-teens fee revenue growth in local currency.

Combined revenue from the capital markets businesses – property sales and commercial mortgage origination – rose 7% (8% local currency). Commercial mortgage origination activity was once again especially strong with revenue up 22% (same local currency).

Global property sales revenue rose 4% (5% local currency). The primary driver was EMEA, which saw a 24% (same local currency) revenue jump, as Germany, Ireland, Spain and the United Kingdom all posted double-digit increases. Americas sales revenue was up 2% (same local currency), paced by a 7% gain in the United States. APAC revenue fell 9% (5% local currency) versus a difficult comparison with the third quarter of 2017.

Recurring revenue from loan servicing activities continued to grow robustly, rising 21% (same local currency). The loan servicing portfolio totaled approximately $196 billion at the end of the third quarter – up 19% from the same period in 2017.

Property management services produced increases of 5% (7% local currency) in revenue and 7% (8% local currency) in fee revenue, supported by continued double-digit growth in outsourced investment accounting and reporting services.

Valuation revenue rose 6% (7% local currency), buoyed by recruiting efforts and productivity gains.

Combined adjusted EBITDA for CBRE’s real estate investment businesses (Global Investment Management and Development Services) rose 44% (same local currency). The Development Services business generated outsized growth from larger-than-usual property sales (reported in equity income from unconsolidated subsidiaries and gains on disposition of real estate).

increases in unemployment and general slowdowns in commercial activity; trends in pricing and risk assumption for commercial real estate services; the effect of significant movements in average cap rates across different property types; a reduction by companies in their reliance on outsourcing for their commercial real estate needs, which would affect our revenues and operating performance; client actions to restrain project spending and reduce outsourced staffing levels; declines in lending activity of U.S. Government Sponsored Enterprises, regulatory oversight of such activity and our mortgage servicing revenue from the commercial real estate mortgage market; our ability to diversify our revenue model to offset cyclical economic trends in the commercial real estate industry; our ability to attract new user and investor clients; our ability to retain major clients and renew related contracts; our ability to leverage our global services platform to maximize and sustain long-term cash flow; our ability to maintain EBITDA and adjusted EBITDA margins that enable us to continue investing in our platform and client service offerings; our ability to control costs relative to revenue growth; economic volatility and market uncertainty globally related to uncertainty surrounding the implementation and effect of the United Kingdom’s referendum to leave the European Union, including uncertainty in relation to the legal and regulatory framework that would apply to the United Kingdom and its relationship with the remaining members of the European Union; foreign currency fluctuations; our ability to retain and incentivize key personnel; our ability to compete globally, or in specific geographic markets or business segments that are material to us; our ability to identify, acquire and integrate synergistic and accretive businesses; costs and potential future capital requirements relating to businesses we may acquire; integration challenges arising out of companies we may acquire; the ability of our Global Investment Management business to maintain and grow assets under management and achieve desired investment returns for our investors, and any potential related litigation, liabilities or reputational harm possible if we fail to do so; our ability to manage fluctuations in net earnings and cash flow, which could result from poor performance in our investment programs, including our participation as a principal in real estate investments; our leverage under our debt instruments as well as the limited restrictions therein on our ability to incur additional debt, and the potential increased borrowing costs to us from a credit-ratings downgrade; the ability of our wholly-owned subsidiary, CBRE Capital Markets, Inc., to periodically amend, or replace, on satisfactory terms, the agreements for its warehouse lines of credit; variations in historically customary seasonal patterns that cause our business not to perform as expected; litigation and its financial and reputational risks to us; our exposure to liabilities in connection with real estate advisory and property management activities and our ability to procure sufficient insurance coverage on acceptable terms; liabilities under guarantees, or for construction defects, that we incur in our Development Services business; our and our employees’ ability to execute on, and adapt to, information technology strategies and trends;

our ability to comply with laws and regulations related to our global operations, including real estate licensure, tax, labor and employment laws and regulations, as well as the anti-corruption laws and trade sanctions of the U.S. and other countries; our ability to maintain our effective tax rate, including during 2018 as we continue to assess the provisional amount recorded based upon our best estimate of the tax impact of the Tax Cuts and Jobs Act (Tax Act) enacted into law on December 22, 2017 in accordance with our understanding of the Tax Act and the related guidance available; changes in applicable tax or accounting requirements, including the impact of any subsequent additional regulation or guidance associated with the Tax Act; and the effect of implementation of new accounting rules and standards (including new lease accounting guidance which will be effective in the first quarter of 2019).

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, 2017 and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2018 and June 30, 2018, 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.

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.

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 items related to acquisitions, reorganization costs, 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.

¹  We adopted new revenue recognition guidance in the first quarter of 2018. 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 for the three months ended September 30, 2018 further excludes contributions from all acquisitions completed after third-quarter 2017. Organic fee revenue for the nine months ended September 30, 2018 further excludes contributions from: (i) all acquisitions completed after first-quarter 2017 for the three months ended March 31, 2018; (ii) all acquisitions completed after the second-quarter of 2017 for the three months ended June 30, 2018; and (iii) all acquisitions completed after the third-quarter of 2017 for the three months ended September 30, 2018.

⁴  Adjusted net income and adjusted earnings per share (or adjusted EPS) exclude the effect of select items 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 the removal 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,  non-cash depreciation and amortization expense related to certain assets attributable to acquisitions, write-off of financing costs on extinguished debt, costs associated with our planned reorganization, costs incurred in connection with a litigation settlement, integration and other costs related to acquisitions and certain carried interest incentive compensation expense (reversal) to align with the timing of associated revenue. Adjustments for the nine months ended September 30, 2018 also included an update to the provisional estimated tax impact of U.S. tax reform initially recorded in the fourth quarter of 2017.

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  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 planned reorganization, costs incurred in connection with a litigation settlement, integration and other costs related to acquisitions, and certain carried interest incentive compensation expense (reversal) to align with the timing of associated revenue.

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.

⁷  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.
