Walker & Dunlop Reports Record Earnings Per Share

Bethesda, MD – August 5, 2015 – Walker & Dunlop, Inc. (NYSE: WD) (the “Company”) reported today second quarter 2015 net income of $20.2 million, or $0.67 per diluted share, a 56% increase from second quarter 2014 net income of $12.9 million, or $0.40 per diluted share. Total revenues were $113.9 million for the second quarter 2015, a 34% increase over the second quarter 2014. Adjusted EBITDA for the second quarter 2015 was $28.9 million compared to $20.9 million for the second quarter 2014, a 39% increase.

“I would like to congratulate every member of the Walker & Dunlop team for generating record revenue and earnings per share during the second quarter of 2015,” commented Walker & Dunlop Chairman and CEO Willy Walker. “Our strong financial results are due to the fantastic group of professionals we have assembled and the market leadership position we have worked very hard to create. We continue to grow and gain market share, all while expanding our brand and expertise across the country.”

Investors in Walker & Dunlop own stock in a company that is generating strong top line revenue growth, record earnings per share, consistent cash flow, and long-term shareholder value by growing our loan servicing portfolio by 20% over the past year with no diminution to the average servicing fee nor average life of the portfolio,” continued Walker.

The investments we have made over the past several years to expand our footprint and product offering are showing strong results. We are in the midst of a mortgage refinancing cycle that is unprecedented. The volume of commercial mortgages originated in 2005, 2006, and 2007 had never been seen before, and the majority of that paper must be refinanced over the next several years. Walker & Dunlop has the platform, people, and market position to benefit tremendously from the need for commercial real estate financing.”

OPERATING RESULTS

TOTAL REVENUES were $113.9 million for the second quarter 2015 compared to $85.3 million for the second quarter 2014, a 34% increase. The increase was driven by the 45% increase in loan originations, which included a 44% increase in lending with Fannie Mae and Freddie Mac. Within the components of revenues, mortgage banking gains increased 34% to $70.0 million, servicing fees increased 17% to $28.1 million, net warehouse interest income increased 70% to $6.6 million and other revenues increased 100% to $8.1 million. The increase in other revenues was driven by fees earned on investment sales volume and $3.0 million in prepayment fee income received during the second quarter 2015, an increase of 73% from the second quarter 2014.

GAINS FROM MORTGAGE BANKING ACTIVITIES for the second quarter 2015 were $70.0 million compared to $52.2 million for the second quarter 2014, a 34% increase. This increase was primarily driven by the substantial growth in loan originations coupled with an increase in the weighted average servicing fee on Fannie Mae loans originated during the quarter. LOAN ORIGINATION FEES were $37.6 million for the second quarter 2015 compared to $29.5 million for the second quarter 2014, a 27% increase. GAINS ATTRIBUTABLE TO MORTGAGE SERVICING RIGHTS (“MSRs”) were $32.4 million for the second quarter 2015 compared to $22.7 million for the second quarter 2014, a 42% increase.

NET WAREHOUSE INTEREST INCOME, which includes interest earned on loans held for sale and our interim loan portfolio, was $6.6 million for the second quarter 2015, a 70% increase over $3.9 million for the second quarter 2014. The increase was driven by the growth in loans held for sale and loans in our interim loan portfolio during the quarter, which generated $4.3 million of interest income from loans held for sale and $2.3 million of interest income from our interim loan portfolio.

TOTAL EXPENSES were $81.3 million for the second quarter 2015 compared to total expenses of $64.4 million for the second quarter 2014, a 26% increase. The increase in total expenses was primarily due to an increase in personnel costs on the strength of our total transaction volume and financial performance, as well as an increase in amortization and depreciation expense resulting from the growth of our mortgage servicing portfolio. Personnel expense for the second quarter 2015 was $46.0 million, an increase of 35% from $34.1 million for the second quarter 2014. Fixed compensation costs have increased following the acquisitions of Johnson Capital and Engler Financial Group, and our variable compensation costs have increased due to greater commission and bonus expenses. Personnel expense as a percentage of total revenues, however, was unchanged from the second quarter 2014 at 40%.

OPERATING MARGIN was 29% for the second quarter 2015 which compared favorably to an operating margin of 25% for the second quarter 2014. The increase in operating margin was driven by the scale of our loan originations business, as total revenues grew 34% while total expenses grew only 26%.

ADJUSTED EBITDA was $28.9 million for the second quarter 2015 compared to $20.9 million for the second quarter 2014, a 39% increase. The increase was driven by significant growth in our cash earnings such as origination fees, servicing fees and net interest income, partially offset by the aforementioned increase in personnel expenses.

ANNUALIZED RETURN ON EQUITY was 20% for the second quarter 2015 compared to 14% for the second quarter 2014. In the second quarter 2015, return on equity benefitted from the increase in net income and the share repurchase which was completed at the end of the first quarter 2015.

TOTAL TRANSACTION VOLUME

TOTAL TRANSACTION VOLUME was $3.8 billion, which includes loan origination volume and investment sales volume. Loan origination volume is comprised of Walker & Dunlop’s core lending and brokerage products, and investment sales volume reflects the sales volume closed by the Company’s new investment sales business.

LOAN ORIGINATION VOLUME was $3.5 billion for the second quarter 2015 compared to $2.4 billion for the second quarter 2014, a 45% increase. Loan originations with Fannie Mae and Freddie Mac were both $1.1 billion representing increases of 21% and 79% from the second quarter 2014, respectively. Brokered loan originations totaled $938.7 million, a 55% increase from the second quarter 2014. HUD loan originations totaled $150.2 million, a 5% decrease from the second quarter 2014. Interim loan originations totaled $106.5 million, a 62% increase from the second quarter 2014. Originations for the Company’s CMBS partnership were $34.7 million for the second quarter 2015 compared to zero for the same quarter last year.

INVESTMENT SALES VOLUME was $319.0 million for the second quarter 2015, its first quarter of operations on our platform.

SERVICING PORTFOLIO

The SERVICING PORTFOLIO totaled $47.7 billion at June 30, 2015, a 20% increase from $39.8 billion at June 30, 2014. During the preceding 12 months, $7.9 billion in net loans were added to the servicing portfolio, of which 83% are Fannie Mae and Freddie Mac loans. The portfolio maintained an average loan term of 10 years and a WEIGHTED AVERAGE SERVICING FEE of 24 basis points. SERVICING FEES were $28.1 million for the second quarter 2015 compared to $24.0 million for the second quarter 2014, a 17% increase, driven by the growth in the portfolio.

CREDIT QUALITY AND RISK-SHARING OBLIGATIONS

The Company’s AT RISK SERVICING PORTFOLIO, which is comprised of loans subject to a defined risk-sharing formula, was $18.4 billion at June 30, 2015 compared to $15.7 billion at June 30, 2014. The Company’s at risk servicing portfolio continues to demonstrate exceptional credit performance, as there were no 60+ DAY DELINQUENCIES at June 30, 2015 or 2014.

THE PROVISION FOR RISK-SHARING OBLIGATIONS associated with loans in the at risk servicing portfolio was $0.1 million for the second quarter 2015 compared to $0.4 million for the second quarter 2014. There were $0.8 million of NET WRITE-OFFS for the second quarter 2015 compared to $1.3 million for the second quarter 2014. Net write-offs represent the settlement of the Company’s guaranty obligations related to losses provisioned for in prior periods.

The on-balance sheet INTERIM LOAN PORTFOLIO, which is comprised of loans for which we have full risk of loss, was $317.3 million at June 30, 2015 compared to $194.3 million at June 30, 2014. Although all of our interim loans are current and performing, the Company provides a general reserve for potential losses. For the second quarter 2015, the provision for loan losses was $0.3 million compared to the second quarter 2014 benefit of $0.1 million.

ACQUISITION OF ENGLER FINANCIAL GROUP

On April 21, 2015, Walker & Dunlop completed its acquisition of 75% of certain assets and assumption of certain liabilities of Engler Financial Group, LLC (“EFG”). EFG is a real estate investment advisory and brokerage firm based in the Southeast serving the multifamily market. The overall purchase price was comprised primarily of cash. On the balance sheet, $1.4 million of the purchase price was allocated to the value of the pipeline of investment sales opportunities, with substantially all the remainder of the purchase price, or $15.7 million, recorded as goodwill.

3

Because the Company only purchased 75% of the net assets, 25% of the goodwill relates to the interest retained by the sellers. The sellers’ interest, or $4.3 million, is presented on the balance sheet as noncontrolling interests. On the income statement, investment sales revenues are included in “Other” revenue, and personnel costs and the other general and administrative costs are presented in the corresponding line items. Noncontrolling interests on the income statement, which was $0.1 million for the second quarter 2015, represents the earnings of the joint venture retained by the sellers.

YEAR-TO-DATE RESULTS

TOTAL REVENUES for the six months ended June 30, 2015 were $226.0 million compared to $150.1 million for the same period last year, a 51% increase. The increase in total revenues was largely driven by a 97% increase in LOAN ORIGINATION VOLUME from $4.0 billion to $7.8 billion, which also contributed to a 64% increase in GAINS FROM MORTGAGE BANKING ACTIVITIES to $142.7 million. The increase in total revenues was also attributable to increases in servicing fees, as well as net interest income received on both loans held for sale and the interim loan portfolio.

TOTAL EXPENSES for the six months ended June 30, 2015 were $158.0 million compared to $117.3 million for the six months ended June 30, 2014, an increase of 35%. The increase in total expenses was due primarily to increased personnel expenses and amortization and depreciation costs. Personnel expenses have increased following our recent acquisitions and as a result of greater commissions and bonus expenses resulting from strong total transaction volume and financial performance. Personnel expenses as a percentage of total revenues for the six months ended June 30, 2015 were 38% compared to 39% for the same period last year. Amortization and depreciation increased $4.6 million due to increased amortization of the growing MSR portfolio, and an additional $5.1 million from the write-off of MSRs following early prepayment in the low interest rate environment.

OPERATING MARGIN for the six months ended June 30, 2015 was 30% compared to operating margin of 22% for the same period last year. Increased scale in our business year over year provided a lift to our operating margin, as revenues have grown 51% while expenses have increased only 35%.

NET INCOME for the six months ended June 30, 2015 was $41.5 million, or $1.32 per diluted share, compared to net income of $20.1 million, or $0.61 per diluted share, for the same period last year, a 107% increase.

ADJUSTED EBITDA was $64.3 million for the six months ended June 30, 2015 compared to $40.7 million for the same period last year, a 58% increase. The increase was driven by significant growth in our cash earnings such as origination fees, servicing fees and net interest income, partially offset by the aforementioned increase in personnel expenses.

Non-GAAP Financial Measures

To supplement the financial statements presented in accordance with United States generally accepted accounting principles (GAAP), the Company presents adjusted EBITDA. Adjusted EBITDA is not a recognized measurement under GAAP. When analyzing our operating performance, readers should use adjusted EBITDA in addition to, and not as an alternative for, net income. Adjusted EBITDA represents net income before income taxes, interest expense on our term loan facility, depreciation and amortization, provision for credit losses, net of write-offs, stock based incentive compensation charges, and removes the benefit of non-cash revenues such as gains attributable to MSRs. Because not all companies use identical calculations, our presentation of adjusted EBITDA may not be comparable to similarly titled measures of other companies. Furthermore, adjusted EBITDA is not intended to be a measure of free cash flow for our management’s discretionary use, as it does not reflect certain cash requirements such as tax and debt service payments. The amounts shown for adjusted EBITDA may also differ from the amounts calculated under similarly titled definitions in our debt instruments, which are further adjusted to reflect certain other cash and non-cash charges that are used to determine compliance with financial covenants.

We use adjusted EBITDA to evaluate the operating performance of our business, for comparison with forecasts and strategic plans, and for benchmarking performance externally against competitors. Since we find adjusted EBITDA to be useful, we believe that investors benefit from seeing results “through the eyes” of management in addition to seeing GAAP results. We believe that this non-GAAP measure, when read in conjunction with the Company’s GAAP financials, provides useful information to investors by offering:

5

Adjusted EBITDA is not in accordance with or an alternative for net income, and may be different from adjusted EBITDA measures used by other companies. We believe that adjusted EBITDA has limitations in that it does not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP and that adjusted EBITDA should only be used to evaluate the Company’s results of operations in conjunction with net income. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income. We compensate for the limitations of this non-GAAP financial measure by relying upon GAAP results to gain a complete picture of our performance.

For more information on adjusted EBITDA, refer to the section of this press release below titled “Adjusted Financial Metric Reconciliation to GAAP.”

For example, a $15 million loan with 50% DUS risk-sharing has the same potential risk exposure as a $7.5 million loan with full DUS risk-sharing. Accordingly, if the $15 million loan with 50% DUS risk-sharing was to default, the Company would view the overall loss as a percentage of the at risk balance, or $7.5 million, to ensure comparability between all risk-sharing obligations. To date, all but three of the Company’s risk-sharing obligations that we have settled have been from full risk-sharing loans.
