MARCUS & MILLICHAP, INC. REPORTS RESULTS FOR

THIRD QUARTER 2016

- Third Quarter Total Revenues Grew 8.9% to $180.6 Million -

CALABASAS, Calif., November 3, 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 third quarter ended September 30, 2016.

Third Quarter 2016 Highlights Compared to Third Quarter 2015

Nine Months 2016 Highlights Compared to Nine Months 2015

“We continued to achieve positive results in the third quarter with 8.9% year-over-year revenue growth and 10.2% sales force growth, relative to a still healthy but changing market environment and a challenging prior year comparable. Our Private Client brokerage revenue grew 6.4% with a transaction increase of 3.1%, amid preliminary reports of a year-over-year decline in market sales, which indicates further expansion in our share,” stated Hessam Nadji, President and Chief Executive Officer. “These results also point to further gains built on 15.2% revenue growth in the Private Client Market segment during the third quarter of 2015. Our success in executing $20 million and above transactions continued in the quarter with a 26.8% increase over the same period last year. Although larger asset sales are more variable from quarter-to-quarter, the ability of our more senior agents and IPA division to service major private and institutional clients remains a positive factor at all price points. We continue to believe that this year’s slowdown in investment sales, in the aftermath of transaction and volume records set in 2015, is a natural part of the real estate cycle. This has been compounded by a number of external factors that have resulted in additional investor and lender caution; however, we expect healthy occupancies, rents and competitive yields to support an active marketplace.”

“As the cycle evolves, we remain focused on helping our clients formulate and execute the right strategies, supporting our agents with investments in technology and best-in-class services and creating value for our stakeholders as we have throughout our 45-year history,” added Mr. Nadji.

Third Quarter 2016 Results Compared to Third Quarter 2015

Total revenues for the third quarter of 2016 were $180.6 million, compared to $165.9 million for the same period in the prior year, increasing by $14.8 million, or 8.9%. The growth in total revenues was primarily driven by the increase in real estate brokerage commissions, which rose by 9.1% to $165.7 million. This improvement in brokerage commissions was partly due to a rise in the proportion of larger transactions, which increased our average transaction size. This was partially offset by a decrease in the average commission fee percentage, as larger transactions generally earn lower commission rates.

Total operating expenses for the third quarter increased by 12.5% to $155.7 million, compared to $138.5 million for the same period in the prior year. The increase was primarily driven by an 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 rose by 150 basis points to 63.0% compared to the same period in the prior year. This was primarily due to an increase in the proportion of transactions closed by our more senior investment sales professionals, who are generally compensated at higher commission rates.

Selling, general and administrative expense rose by $5.1 million, or 14.3% during the third 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 the expansion of services for our investment sales and financing professionals; (ii) expansion of existing offices; (iii) legal fees and (iv) sales and promotional marketing expenses to support additional sales activity. These costs were partially offset by lower management performance-related compensation and lower stock-based compensation expense.

Net income for the third quarter of 2016 was $15.1 million, or $0.39 per common share (basic and diluted), compared to net income of $15.2 million, or $0.39 per common share (basic and diluted) for the same period in the prior year. Adjusted EBITDA for the third quarter of 2016, decreased modestly by 5.1% to $28.1 million, compared to adjusted EBITDA of $29.6 million for the same period in the prior year.

Nine Months 2016 Results Compared to Nine Months 2015

Total revenues for the nine months ended September 30, 2016, were $528.3 million, compared to $485.9 million for the same period in the prior year, increasing $42.4 million, or 8.7%. Total operating expenses for the nine months ended September 30, 2016, were up 11.0% to $449.7 million compared to $405.2 million for the same period in the prior year. Cost of services as a percent of total revenues rose modestly by 80 basis points to 61.2%, compared to 60.4% in the first nine months of 2015. Net income for the nine months ended September 30, 2016, was $47.5 million, or $1.22 (basic and diluted) compared with net income of $46.4 million, or $1.19 per common share (basic and diluted) for the same period in the prior year. Adjusted EBITDA for the nine months ended September 30, 2016, decreased slightly by 2.1% to $87.0 million, from $88.9 million for the same period in the prior year. As of September 30, 2016, the Company had 1,671 investment sales and financing professionals.

Business Outlook

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

Several factors likely to influence the Company’s business given the current market environment include:

These factors highlight the importance of viewing the Company’s business through an annual perspective. Fourth quarter 2016 year-over-year comparisons will be challenging in light of current market conditions when compared to fourth quarter 2015’s total and Private Client Market segment brokerage transaction growth rates of 15.2% and 29.2%, respectively.

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):
