Second Quarter 2014 Highlights

Year-to-Date Highlights

Commenting on the Company’s results, John J. Kerin, Marcus & Millichap’s President and Chief Executive Officer, said, “The momentum we generated early in the year continued into the second quarter, producing strong results for the Company throughout the first-half of 2014.

Revenues in the second quarter grew by 27.3% year-over-year for the quarter and 42.3% year to date due to the strength in our core private client market as well as positive results related to our various growth initiatives.”

Kerin continued, “We saw strong increases in our second quarter key operating metrics for our real estate brokerage business, including average number of sales professionals, total number of transactions and total sales volume over the same period in the prior year. While our growth continues to be driven by transactions for retail and multi-family properties, I am pleased with our expansion in the office and hospitality groups. We also remain focused on expanding our geographic footprint with strong growth in the second quarter from regions in the eastern United States. Key market indicators and our business pipeline remain favorable.”

Second Quarter 2014 Results

Total revenues for the second quarter of 2014 were $134.3 million, compared to $105.5 million for the same period in the prior year, an increase of $28.8 million, or 27.3%. The increase in total revenues is primarily a result of increases in revenues from real estate brokerage commissions which increased to $123.3 million for the three months ended June 30, 2014 from $95.8 million for the same period in the prior year, an increase of $27.5 million or 28.7%. This increase was primarily driven by a combination of an increase in the number of investment sales transactions and an increase in the average commission size, offset by a slight decrease in average commission rates during the three months ended June 30, 2014 as compared to the same period in the prior year. Financing fees and other revenues contributed the remaining increase in total revenues.

Total operating expenses for the second quarter of 2014 were $112.5 million, compared to $91.3 million for the same period in the prior year, an increase of $21.2 million, or 23.3%. The increase was primarily driven by an $18.1 million increase 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 to 59.3% compared to 58.3% for the same period in the prior year primarily due to an increase in the proportion of transactions closed by our more senior investment sales professionals who are compensated at higher commission rates. In addition, selling, general and

Page 2

administrative expense increased by $3.0 million, or 10.4% during the second quarter of 2014 as compared to the same period in the prior year. The increase was due primarily to (i) an increase in salaries and related benefits driven by an increase in headcount in the areas of recruiting and corporate support in connection with our growth and with being a public company; (ii) an increase in legal costs and accruals; (iii) an increase in management performance related compensation driven by the increase in operating results; and (iv) increases in other expense categories primarily driven by our business growth. The increases were partially offset by a decrease in stock-based compensation expense due to the replacement of the pre-IPO stock-based compensation award program.

Net income for the second quarter of 2014 was $12.8 million or $0.33 per common share (Basic and Diluted) compared to net income of $8.0 million for the same period in the prior year. Adjusted EBITDA for the second quarter of 2014 was $24.0 million compared to adjusted EBITDA of $17.1 million for the same period in the prior year.

Year-to-date Results

The Company reported total revenues of $248.9 million for the six months ended June 30, 2014, an increase of $74.0 million, or 42.3%, compared to revenues of $174.8 million for the same period in the prior year. Operating expenses for the six months ended June 30, 2014, were $215.1 million compared to $158.0 million for the same period in the prior year, representing an increase of $57.1 million, or 36.1%. The Company reported net income for the six months ended June 30, 2014 of $19.6 million compared with net income of $9.6 million for the same period in the prior year. Adjusted EBITDA for the six months ended June 30, 2014 was $37.5 million, which represents an increase of $16.4 million, or 77.5%, as compared to $21.1 million for the same period in the prior year.

Business Outlook

Commenting on the Company’s business outlook, Mr. Kerin said, “We are very pleased with our year-over-year growth in the first half of 2014 and continue to expect positive results for the remainder of the year. The combination of an improving real estate market and our growth initiatives should drive solid results for the Company in the remainder of 2014.”

ADJUSTED EBITDA RECONCILIATION

(Unaudited)

Adjusted EBITDA, which the Company defines as net income before interest income/expense, taxes, 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. 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 GAAP financial measure, net income, to Adjusted EBITDA is as follows (in thousands):
