FOURTH QUARTER 2016

- Full Year Total Revenues Increased 4.1% to $717.5 Million -

- Market Share Expanded in a Slowing Transaction Market -

CALABASAS, Calif., March 9, 2017 — (BUSINESS WIRE) — Marcus & Millichap, Inc. (the “Company”, “Marcus & Millichap”, “MMI”) (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 fourth quarter and full year ended December 31, 2016.

Full Year 2016 Highlights Compared to Full Year 2015

Fourth Quarter 2016 Highlights Compared to Fourth Quarter 2015

“2016 was a year of transition in the marketplace. Our team’s experience and steadfast focus on client results enabled us to help investors navigate a changing environment while gaining market share,” said Hessam Nadji, president and CEO. “The fourth quarter was particularly challenging as the post-election jump in interest rates resulted in re-pricing of many pending transactions, especially smaller, private client deals, which typically have higher debt ratios. We also saw a wait-and-see stance anticipating the Trump administration’s tax reform, regulatory easing and economic initiatives. Beyond these headwinds, healthy property fundamentals and favorable investor demographics, coupled with the administration’s proposals, bode well for the real estate market and generating more activity once policy clarity emerges,” he added.

“As with many market shifts and changes throughout our 46-year history, MMI remains focused on long-term growth in a large and fragmented marketplace through an unwavering emphasis on client service, share gains and strengthening our platform. Last year’s investments in infrastructure, proprietary brokerage technology and salesforce expansion reflect this commitment,” he continued.

“We believe these investments combined with the our leading brand and highly specialized salesforce will continue to be the winning formula for maximizing and preserving wealth for clients in a fluid market and creating long-term value for our shareholders,” he concluded.

Full Year 2016 Results Compared to Full Year 2015

Total revenues for the year ended December 31, 2016 were $717.5 million, compared to $689.1 million for the same period in the prior year, increasing by 4.1%. Total operating expenses for the year ended December 31, 2016 were up 6.4% to $610.9 million compared to $574.4 million for the same period in the prior year. Cost of services as a percent of total

revenues rose by 60 basis points to 62.0%, compared to 61.4% for the same period in the prior year. Net income for the year ended December 31, 2016 was $64.7 million, or $1.66 (basic and diluted) per common share, compared with net income of $66.4 million, or $1.71 (basic) and $1.69 (diluted) per common share, for the same period in the prior year. Adjusted EBITDA for the year ended December 31, 2016, decreased by 4.7% to $118.3 million, from $124.1 million for the same period in the prior year. As of December 31, 2016, the Company had 1,737 investment sales and financing professionals.

Fourth Quarter 2016 Results Compared to Fourth Quarter 2015

Total revenues for the fourth quarter of 2016 were $189.2 million, compared to $203.2 million for the same period in the prior year, decreasing by 6.9%. The reduction in total revenues was primarily driven by the decrease in real estate brokerage commissions, which declined by 7.2% to $172.7 million. This reduction in brokerage commissions was primarily due to a decrease in number of transactions and average commission fee percentage. The average commission fee percentage decrease was driven by the rise in the proportion of larger transactions, which generally earn a lower commission rate.

Total operating expenses for the fourth quarter of 2016 decreased by 4.7% to $161.3 million, compared to $169.2 million for the same period in the prior year. The decrease was primarily driven by a 6.2% reduction 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 50 basis points to 64.3% 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 for the fourth quarter of 2016 decreased by 0.7% to $38.4 million, compared to $38.6 million for same period in the prior year. The decrease was primarily due to lower management performance-based compensation partially offset by the increase in (i) sales and promotional marketing expenses to support additional sales activity; (ii) stock-based compensation expense due to variability in our stock price; (iii) expansion of existing offices; (iv) legal costs and (v) other selling, general and administrative expenses.

Net income for the fourth quarter of 2016 was $17.2 million, or $0.44 per common share (basic and diluted), compared to net income of $19.9 million, or $0.51 per common share (basic and diluted), for the same period in the prior year. Adjusted EBITDA for the fourth quarter of 2016 was $31.3 million compared to adjusted EBITDA of $35.3 million for the same period in the prior year.

Business Outlook

We believe that we are well positioned to gain market share by leveraging a number of factors, including our leading national brand predominantly within the Private Client Market segment and specialty groups, experienced management team, infrastructure investments and proprietary technology. The size and fragmentation of the Private Client Market segment, in particular, continues to offer long-term growth opportunities with top ten brokers making up only 24% market share. This market segment consistently accounts for over 80% of commercial property sales transactions and 60% of the commission pool. 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, Marcus & Millichap Capital Corporation.

Key factors likely to influence the Company’s business in 2017:

These factors, in addition to the business’s typical transaction closing date variability, highlight the importance of viewing the Company’s business through a long-term, at least annual perspective. First quarter 2017 year-over-year comparisons will be challenging in light of the exceptionally strong trends in the first quarter of 2016 in contrast to current, short-term market

conditions including the impact of increasing interest rates. In addition, the Company’s strategic increase in investments in infrastructure and systems improvement are ongoing to position the firm for long-term growth. Expense leveraging is not expected until late 2017-2018.

Adjusted EBITDA Reconciliation

Adjusted EBITDA, which the Company defines as net income before (i) interest income and other, including net realized (losses) gains on marketable securities, available-for-sale and cash and cash equivalents, (ii) interest expense, (iii) provision for income taxes, (iv) depreciation and amortization and (v) stock-based compensation. The Company uses Adjusted EBITDA in its business operations to evaluate the performance of its business, develop budgets and measure its performance against those budgets, among other things. 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 Adjusted EBITDA 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):
