MARCUS & MILLICHAP, INC. REPORTS RESULTS FOR

FIRST QUARTER 2016

- Total Revenues Grew 12.1% to $164.3 Million -

CALABASAS, Calif., May 5, 2016 —(BUSINESS WIRE)— Marcus & Millichap, Inc. (the “Company”, “Marcus & Millichap”) (NYSE: MMI), a leading national brokerage firm specializing in commercial real estate investment sales, financing, research and advisory services, today reported financial results for the first quarter ended March 31, 2016.

First Quarter 2016 Highlights Compared to First Quarter 2015

“The first quarter marked another period of growth for Marcus & Millichap as we celebrate our 45th year in the business. Our $1-$10 million private client market segment registered healthy results which points to additional market share gains,” stated Hessam Nadji, Company President and CEO. “Our first quarter performance also benefited from other factors, including closing date variability, a jump in larger asset sales and a major portfolio transaction.”

Mr. Nadji continued, “Market sentiment has shifted positively from early in the year. The economy continues to post modest, yet steady growth and real estate fundamentals remain healthy, all of which provide a positive market backdrop for our business. However, we are still seeing longer marketing and closing timelines due to buyer and lender caution, as the market evolves from several years of rapid recovery. Our management team continues to execute our long-term growth plan which is on track and has been proven effective through various market shifts and cycles.”

First Quarter 2016 Results Compared to First Quarter 2015

Total revenues for the first quarter of 2016 were $164.3 million, compared to $146.5 million for the same period in the prior year, an increase of $17.7 million, or 12.1%. The growth in total revenues was primarily driven by the increase in revenues from real estate brokerage commissions which rose by 14.5% to $153.7 million for the quarter compared to the same period in the prior year. This improvement was due to growth in the number of investment sales transactions and the average transaction size, partially offset by a decrease in average commission rates due to a larger proportion of our transactions that closed in the >$20 million market segment, which generate lower commission rates. Growth in financing fees, partially offset by a reduction in other revenues, contributed the remaining increase in total revenues.

Total operating expenses for the first quarter of 2016 were $139.4 million, compared to $122.8 million for the same period in the prior year, rising by $16.6 million, or 13.6%. The increase was primarily driven by a $10.0 million, or 11.6%, rise in cost of services, which are variable commissions paid to the Company’s investment sales professionals and compensation-related costs in connection with our financing activities. Cost of services as a percent of total revenues was 58.5% compared to 58.8% for the same period in the prior year, primarily due to a reduction in referral fees.

Selling, general and administrative expense rose by $6.4 million, or 17.9% during the first quarter of 2016 as compared to the same period in the prior year. The increase was primarily due to (i) sales and promotional marketing expenses to support additional sales activity and the Company’s annual sales recognition event; (ii) expansion of existing offices; (iii) salaries and related benefits as a result of growth in headcount to support expansion of services for our investment sales and financing

professionals; and (iv) an increase in legal costs and accruals partly driven by a settlement with an insurance carrier during the first quarter of 2015, which reduced legal costs in that period. These costs were partially offset by lower stock-based compensation expense.

Net income for the first quarter of 2016 was $14.8 million, or $0.38 per common share (basic and diluted), compared to net income of $13.7 million, or $0.35 per common share (basic and diluted), for the same period in the prior year. Adjusted EBITDA for the first quarter of 2016 was $27.2 million compared to adjusted EBITDA of $26.3 million for the same period in the prior year.

Business Outlook

The Company is well-positioned to leverage its leading private client brand, experienced management team and investments in infrastructure, tools and technology to build on its recent successes. The vast and highly fragmented private client market segment ($1-$10 million) continues to be a pillar of the Company’s business with opportunities for continued market share gains. The Company’s strong 2015 performance makes year-over-year comparisons challenging, coupled with lengthening marketing periods and a heightened level of caution among buyers and lenders amid a maturing cycle.

Adjusted EBITDA Reconciliation

Adjusted EBITDA, which the Company defines as net income before interest income/expense, taxes, net realized gains on marketable securities, available-for-sale, depreciation and amortization and stock-based compensation is a non-GAAP financial measure. 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. generally accepted accounting principles (“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 the most directly comparable U.S. GAAP financial measure, net income, to Adjusted EBITDA is as follows (in thousands):
