Highlights for the quarter include:

Commenting on results in the latest quarter, John J. Kerin, Marcus & Millichap’s President and Chief Executive Officer, said, “I am very pleased with our performance in the third quarter,

particularly our strong year-over-year growth in revenue and adjusted EBTIDA. These results reflect the continued momentum generated by our core brokerage operations, which included a nearly 24.0% increase in total sales volume and a solid 6.5% uptick in transaction size.”

Mr. Kerin continued, “We continue to benefit from improving commercial real estate fundamentals and our focus on the private client segment of the marketplace, which includes commercial real estate transactions in the $1 million to $10 million price range. In addition, we are also making good progress on growing market share in larger transactions and expanding our financing operations. With the completion of our initial public offering earlier this month, we are well-positioned to continue to execute on this growth strategy.”

The Spin-Off and Initial Public Offering

On November 5, 2013, the Company completed its initial public offering (the “IPO”) of 6,900,000 shares of common stock at a price to the public of $12.00 per share, which consisted of 4,173,413 shares of common stock sold by the Company, including 900,000 shares of common stock pursuant to the exercise of the underwriters’ option to purchase additional shares and 2,726,587 shares of common stock sold by the selling stockholders. The IPO generated net proceeds to the Company of approximately $42.7 million, including the underwriters’ full exercise of their option to purchase additional shares and after deducting total expenses of approximately $7.4 million, consisting of $3.5 million of underwriters’ discounts and commissions and IPO related expenses estimated to be $3.9 million. We did not receive any proceeds from the sale of the shares by the selling stockholders. Prior to the completion of the IPO, the shareholders of Marcus and Millichap Real Estate Investment Services, Inc. (“MMREIS”) contributed all of the outstanding shares of capital stock of MMREIS to the Company in exchange for the Company’s common stock, pursuant to which MMREIS became the Company’s wholly owned subsidiary, Thereafter, Marcus & Millichap Company (“MMC”) distributed 80.0% of the shares of the Company’s common stock to MMC’s shareholders and exchanged the remaining portion of its shares of the Company’s common stock for cancellation of indebtedness. Mr. Marcus, the Company’s Founder and Co-Chairman, continues to own indirectly approximately 68.0% of the Company’s fully diluted shares.

Third Quarter 2013 Results

Total revenues for the third quarter of 2013 were $112.0 million, compared to $91.2 million for the third quarter of 2012, an increase of $20.7 million, or 22.7%. The increase in total revenues is primarily a result of increases in real estate brokerage commissions, which contributed 92.3% of the total increase, as well as an increase in financing fees.

Revenues from real estate brokerage commissions increased to $101.8 million in the third quarter of 2013, up 23.2% from $82.6 million in the same period last year due a combination of a 16.5% increase in the number of investment sales transactions and a 5.7% increase in the average commission. The increase in average commission size was primarily due to an increase in the average transaction size.

Revenues from financing fees increased to $6.8 million in the third quarter of 2013, up $1.6 million, or 30.6%, from $5.2 million in the third quarter of 2012. The increase was primarily driven by a 40.2% increase in the number of loan transactions due to an increase in the number of financing professionals combined with an increase in their productivity levels, partially offset by a 6.9% decrease in average loan commissions due in part to an increase in the proportion of fees from smaller loan transactions.

Other revenues were $3.4 million for the third quarter of 2013 and 2012.

Operating expenses for the third quarter of 2013 totaled $99.3 million, compared to $79.9 million for the same period last year, an increase of $19.4 million, or 24.3%. The increase was driven by an increase in cost of services which is primarily commissions paid to our investment sales professionals and compensation-related costs related to our financing activities. Selling, general and administrative costs increased as well. This was in part due to higher staff salaries, wages and related benefits expenses driven by an increase in our average headcount to build and support our sales force, including hiring of national and regional specialty directors and sales recruiters. Legal costs were driven by an increase in legal settlements combined with lower insurance recoveries in the current quarter as compared to the same period last year and other administrative costs were higher primarily due to an increase in professional fees driven by third party consulting services fees in preparation of being a public company.

Net income for the third quarter of 2013 was $7.3 million, compared to net income of $6.4 million in the third quarter of last year.

Nine Month Results

The Company reported total revenues of $286.8 million for the nine months ended September 30, 2013, an increase of $48.7 million, or 20.5%, compared to revenues of $238.1 million during the same period in 2012. Operating expenses for the nine months ended September 30, 2013 was $257.3 million compared to $212.0 million for the nine months ended September 30, 2012, representing an increase of $45.3 million, or 21.4%. The Company reported net income for the nine month period ended September 30, 2013 of $16.9 million, an increase of approximately $2.0 million, or 13.6%, compared with $14.9 million for the nine month period ended September 30, 2012. Adjusted EBITDA for the first nine months of 2013 was $36.8 million, which represents an increase of $4.4 million, or 13.5%, as compared to $32.4 million for the first nine months of 2012.

Business Outlook

Commenting on the Company’s business outlook, Mr. Kerin said, “Typically, the fourth quarter generates approximately one-third of Marcus & Millichap’s full year transaction volume and revenue—and we expect normal seasonal patterns to continue in the fourth quarter of 2013. However, during the fourth quarter last year, commercial real estate investors’ uncertainty associated with the looming ‘fiscal cliff’ resulted in investors expediting transactions that would have normally closed in 2013. Therefore, we do not expect to see the same level of growth in the current fourth quarter.”

ADJUSTED EBITDA RECONCILIATION

(Unaudited)

This press release includes a non-GAAP financial measure, Adjusted EBITDA, which the Company defines as net income before interest income/expense, taxes, depreciation and amortization and stock-based compensation. The Company uses Adjusted EBITDA in its business operations to, among other things, evaluate the performance of its business, develop budgets and measure its performance against those budgets. The Company also believes that analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate its overall operating performance. However, Adjusted EBITDA has material limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under U.S. GAAP. The Company finds Adjusted EBITDA as a useful tool to assist in evaluating performance because it eliminates items related to capital structure and taxes and non-cash stock-based compensation charges. In light of the foregoing limitations, the Company does not rely solely on Adjusted EBITDA as a performance measure and also considers its U.S. GAAP results. Adjusted EBITDA is not a measurement of the Company’s financial performance under U.S. GAAP and should not be considered as an alternative to net income, operating income or any other measures derived in accordance with U.S. GAAP. Because Adjusted EBITDA is not calculated in the same manner by all companies, it may not be comparable to other similarly titled measures used by other companies.

A reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure, net income, is as follows (in thousands):
