MARCUS & MILLICHAP, INC. REPORTS RESULTS FOR

SECOND QUARTER 2016

– Second Quarter Revenues Grew 5.7% to $183.4 Million –

CALABASAS, Calif., August 4, 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 second quarter ended June 30, 2016.

Second Quarter 2016 Highlights Compared to Second Quarter 2015

Six Months 2016 Highlights Compared to Six Months 2015

“In the second quarter, Marcus & Millichap continued to grow, while gaining share in the vital Private Client Market segment, in light of flat year-over-year sales in the market after several years of strong recovery,” stated Hessam Nadji, President and Chief Executive Officer. “An increase in larger transactions valued at $20 million and above, which are more variable from quarter-to-quarter, also contributed to our results. While executing larger transactions is complementary to our private client business, these overall positive results reflect the client service focus and capabilities of our team, particularly in a transitioning market environment.”

Mr. Nadji continued, “We see healthy property fundamentals with supply and demand in balance and competitive yields still attracting capital into commercial real estate. At the same time, a maturing cycle, macroeconomic concerns and recent global events weigh on investor sentiment, which continues to pressure the bid/ask spread and extended transaction timelines. Nevertheless, we are experiencing ample buyer interest, healthy transaction closing ratios and a wide range of lenders active in the marketplace. Our United States centric, well-capitalized platform, leading and still-growing position within the Private Client Market segment, 45-year culture of client service, versatility in executing larger transactions and highly experienced management team position us for long-term growth,” added Mr. Nadji.

Second Quarter 2016 Results Compared to Second Quarter 2015

Total revenues for the second quarter of 2016 were $183.4 million, compared to $173.5 million for the same period in the prior year, an increase of $9.9 million, or 5.7%. The growth in total revenues was primarily driven by the increase in real estate brokerage commissions which rose by 6.2% to $170.1 million. 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 higher priced transactions, which generate lower commission rates.

Total operating expenses for the second quarter increased by 7.4% to $154.6 million, compared to $144.0 million for the same period in the prior year. The increase was primarily driven by a 7.2% 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 increased by 90 basis points to 61.7% compared to the same period in the prior year, primarily due to an increase in proportion of transactions closed by our more senior investment sales professionals, who are generally compensated at higher commission rates, partially offset by a reduction in referral fees.

Selling, general and administrative expense rose by $2.8 million, or 7.5% during the second quarter of 2016 compared to the same period in the prior year. The increase was primarily due to (i) salaries and related benefits as a result of growth in headcount to support expansion of services for our investment sales and financing professionals; (ii) expansion of existing offices and (iii) sales and promotional marketing expenses to support additional sales activity. These costs were partially offset by lower management performance-related compensation, lower stock-based compensation expense and a reduction in legal fees.

Net income for the second quarter of 2016 was $17.5 million, or $0.45 per common share (basic and diluted), compared to net income of $17.6 million, or $0.45 per common share (basic and diluted), for the same period in the prior year. Adjusted EBITDA for the second quarter of 2016 was $31.8 million compared to adjusted EBITDA of $33.0 million for the same period in the prior year.

Six Months 2016 Results Compared to Six Months 2015

Total revenues for the six months ended June 30, 2016, were $347.7 million, compared to $320.0 million for the same period in the prior year, an increase of $27.6 million, or 8.6%. Total operating expenses for the six months ended June 30, 2016, were up 10.2% to $294.0 million compared to $266.7 million for the same period in the prior year. Cost of services as a percent of total revenues rose slightly to 60.2%, compared to 59.9% in the first six months of 2015. The Company reported net income for the six months ended June 30, 2016, of $32.3 million, or $0.83 (basic and diluted), compared with net income of $31.2 million, or $0.80 per common share (basic and diluted) for the same period in the prior year. Adjusted EBITDA for the six months ended June 30, 2016, decreased modestly by 0.6% to $58.9 million, from $59.3 million for the same period in the prior year. As of June 30, 2016, the Company had 1,622 investment sales and financing professionals.

Business Outlook

The Company is leveraging its leading national brand, particularly within the Private Client Market segment, experienced management team, infrastructure investments and proprietary technology, to gain additional market share. We believe that the size and fragmentation of the Private Client Market segment, in particular, continue to offer long-term growth opportunity. The Company’s growth plan also includes further expansion into various specialty property types such as hospitality, self-storage and seniors housing, as well as expansion of its financing division, MMCC.

Several factors are likely to influence the Company’s business given the current market environment. First, the Company’s Private Client Market segment is growing at a more modest pace given the flat year-over-year sales trend in the marketplace. Secondly, extended transaction timelines and bid/ask spreads are exacerbating the closing date variability common in the brokerage business. In addition, the Company’s sales valued at $20 million and above posted accelerated gains in the first six months of 2016, but have shown greater variability quarter-to-quarter. These factors highlight the importance of viewing the Company’s business through an annual perspective. Third quarter 2016 year-over-year comparisons will be challenging in light of the Company’s third quarter 2015 total transaction growth rate of 11.8% and Private Client Market segment brokerage transaction growth rate of 17.6%.

Management remains focused on hiring, training and growing the Company’s salesforce and improving productivity through technology and brokerage support initiatives. Marcus & Millichap’s expansive market research and specialized real estate investment brokerage platform are cornerstones in helping investors develop and execute the best strategy and successfully navigate market shifts and changes, as demonstrated throughout our 45-year history.

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):
