FOURTH QUARTER 2014 HIGHLIGHTS

FULL YEAR 2014 HIGHLIGHTS

Bethesda, MD – February 12, 2015 – Walker & Dunlop, Inc. (NYSE: WD) (the “Company”) announced today fourth quarter and full year 2014 results. Total revenues for the fourth quarter 2014 were $112.6 million, a 32% increase over fourth quarter 2013. Revenue growth was driven by record origination volume including significant increases in lending with Fannie Mae and Freddie Mac. Fourth quarter 2014 GAAP net income and adjusted net income, which excludes certain items¹, increased to $16.3 million, or $0.50 per diluted share, from fourth quarter 2013 GAAP net income of $11.2 million and adjusted net income of $11.4 million, or $0.33 of GAAP and adjusted diluted earnings per share. Adjusted EBITDA for the fourth quarter 2014 was $23.4 million compared to $17.9 million for the same period last year, a 31% increase. Total revenues for 2014 were a record $360.8 million, a 13% increase from 2013. GAAP net income for

2014 increased 24% to $51.4 million, or $1.58 per diluted share, from $41.5 million, or $1.21 per diluted share in 2013. Adjusted net income for 2014 increased 18% to $51.7 million, or $1.59 per diluted share, from $44.0 million, or $1.28 per diluted share in the prior year. Adjusted EBITDA for 2014 was $84.8 million compared to $56.8 million in 2013, a 49% increase.

“The fourth quarter was an exceptional finish to a very strong year,” commented Walker & Dunlop Chairman and CEO Willy Walker, “Our record origination volumes and revenues and our 24% growth in year-over-year adjusted earnings per share are a testament to the great team we have in place. Since we went public in 2010, the volume of commercial real estate loan refinancings has declined every year, yet Walker & Dunlop has grown revenues at a compound annual growth rate of 31% over that period. We are now faced with dramatic increases in refinancing volumes and have built one of the strongest brands and platforms in our industry to meet that opportunity.

“As we look ahead,” Walker continued, “the publication of the 2015 GSE scorecard in January clears the way for Walker & Dunlop to remain one of the dominant providers of capital to the multifamily industry given our ranking as the #1 Fannie Mae DUS lender and #3 Freddie Mac Program Plus Seller by volume in 2014. The acquisition of Johnson Capital in Q4 2014 and continued recruiting of new production talent across our entire lending platform positions us extremely well for the increased deal flow in the coming years. And with exceedingly low interest rates and significant domestic and foreign capital looking to invest in commercial real estate, we are very excited about the macro-economic drivers of our business over the next few years.”

OPERATING RESULTS

TOTAL REVENUES for the fourth quarter 2014 were $112.6 million compared to $85.5 million for the fourth quarter 2013, a 32% increase. The increase in total revenues was driven by the 83% increase in loan origination volume, which included a 188% increase in lending with Fannie Mae and Freddie Mac. Within the components of revenue, mortgage banking gains increased 37% to $71.9 million, servicing fees increased 10% to $26.1 million, net warehouse interest income on loans held for sale increased 161% to $4.4 million, net interest income on interim loans increased 223% to $1.9 million and other revenue increased 20% to $7.1 million. Total revenues were $360.8 million for 2014 compared to $319.0 million for the prior year, a 13% increase.

GAINS FROM MORTGAGE BANKING ACTIVITIES for the fourth quarter 2014 were $71.9 million compared to $52.4 million for the fourth quarter 2013, a 37% increase. This increase in gains from mortgage banking was primarily driven by the increase in origination volumes during the quarter. LOAN ORIGINATION FEES were $39.8 million for the fourth quarter 2014 compared to $31.0 million for the fourth quarter 2013, a 28% increase. GAINS ATTRIBUTABLE TO MORTGAGE SERVICING RIGHTS (“MSRs”) were $32.1 million in the fourth quarter 2014 compared to $21.4 million in the fourth quarter 2013, a 50% increase. For the full year, GAINS FROM MORTGAGE BANKING ACTIVITIES were $222.0 million compared to $203.7 million for the prior year, a 9% increase. LOAN ORIGINATION FEES were $125.5 million for 2014 compared to $111.7 million for the prior year, a 12% increase. MSRs were $96.5 million for 2014 compared to $92.0 million for the prior year, a 5% increase.

GAAP TOTAL EXPENSES were $86.0 million for the fourth quarter 2014 compared to GAAP total expenses of $67.5 million for the fourth quarter 2013, a 27% increase, and adjusted total expenses¹ of $65.3 million for the fourth quarter 2013, a 32% increase. The increase in total expenses was due to the rise in variable compensation as a result of the growth in loan origination volume, an increase in bonus expense based on the year-over-year improvement in Company performance, as well as an increase in interest expense on corporate debt resulting from the closing of our $175 million term loan facility in the fourth quarter 2013. In addition, fourth quarter 2014 expenses include a one-time

2

charge of $1.3 million related to the accelerated pay-out of future servicing fees resulting from the termination of our joint venture with ARA. Personnel expense for the fourth quarter 2014 was $48.9 million, an increase of 32% from $37.0 million for the fourth quarter 2013 primarily due to higher variable compensation. Personnel expense as a percentage of total revenues in the fourth quarter 2014 was 43%. GAAP TOTAL EXPENSES for 2014 were $276.9 million compared to GAAP total expenses of $252.3 million for the prior year, a 10% increase. Adjusted total expenses were $276.4 million for 2014 compared to adjusted total expenses of $246.5 million for 2013, a 12% increase. The increase in total expenses is primarily the result of a 175% increase in corporate debt expense and a 12% increase in personnel expense stemming primarily from increased production.

GAAP INCOME FROM OPERATIONS was $26.6 million for the fourth quarter 2014, an increase of 48% over the fourth quarter 2013 GAAP income from operations and 45% over the fourth quarter 2013 adjusted income from operations¹, producing GAAP and ADJUSTED OPERATING MARGINS¹ of 24% compared to 21% for the fourth quarter 2013. 2014 GAAP income from operations was $83.9 million, an increase of 26% over the prior year, producing a GAAP operating margin of 23%, compared to 21% for the same period last year. 2014 adjusted income from operations was $84.4 million, an increase of 19% over the prior year, producing an adjusted operating margin of 23% compared to 22% for the same period last year.

ADJUSTED EBITDA for the fourth quarter 2014 was $23.4 million compared to $17.9 million for the same period last year, a 31% increase. Adjusted EBITDA for 2014 was $84.8 million compared to $56.8 million in the prior year, an increase of 49%. The year-over-year increase was primarily a result of the $13.8 million increase in loan origination fees, an $8.2 million growth in servicing revenues, a $10.0 million increase in net warehouse and interim loan interest income and a decrease in net write offs of $3.9 million, partially offset by commissions and variable compensation increases.

LOAN ORIGINATION VOLUME

LOAN ORIGINATIONS increased 83% to a record $4.3 billion in the fourth quarter 2014 with loans originated for Fannie Mae and Freddie Mac increasing 188% from the fourth quarter 2013. Volumes with Fannie Mae and Freddie Mac contributed 69% of total origination volume in the fourth quarter 2014 compared to 44% in the fourth quarter 2013. For the full year, loan originations were $11.4 billion compared to $8.4 billion for 2013, a 35% increase. Volume with Fannie Mae and Freddie Mac totaled $7.6 billion, or 67% of 2014 origination volume, up from 53% last year. Originations with Freddie Mac grew 112%, the primary contributor of the 71% increase in GSE originations. This increase in GSE volumes drove the Company’s market share with Freddie Mac to 10.0% this year from 7.7% in 2013 and market share with Fannie Mae to 12.4% this year from 11.3% in 2013. Interim lending grew 77% over 2013 as the Company increased its on-balance sheet interim loans by 66%. Brokered loans were flat year over year and HUD lending decreased 38% in 2014 over 2013. The Company’s CMBS partnership, which began making loans in 2014, originated $116.1 million of loans during the year, $89.5 million of which was originated by the Company’s originators.

SERVICING PORTFOLIO

The SERVICING PORTFOLIO totaled $44.0 billion at December 31, 2014, a 13% increase from $38.9 billion at December 31, 2013. $5.1 billion in net loans were added to the servicing portfolio during the period, of which 75% were Fannie Mae and Freddie Mac loans. The Johnson Capital acquisition added approximately $0.6 billion of HUD servicing to the Company’s portfolio during 2014. The average duration of the portfolio is 10.3 years, and 84% of the servicing fees remain prepayment protected.

SERVICING FEES were $26.1 million for the fourth quarter 2014, compared to $23.8 million for the fourth quarter 2013, a 10% increase. In the fourth quarter 2014 servicing fees were 23% of total revenues. Servicing fees for the year were $98.4 million compared to $90.2 million for the prior year, a 9% increase. Servicing fees were 27% of total revenues in 2014.

The WEIGHTED AVERAGE SERVICING FEE at December 31, 2014 remained unchanged at 24 basis points from December 31, 2013.

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 $17.4 billion at December 31, 2014 compared to $15.1 billion at December 31, 2013.

The Company’s at risk servicing portfolio continues to demonstrate strong credit performance, as exemplified by the following credit metrics:

60+ DAY DELINQUENCIES were $16.6 million, or 10 basis points of the at risk servicing portfolio, at December 31, 2014 compared to $3.3 million, or two basis points of the at risk servicing portfolio, at December 31, 2013. There were no delinquencies in the Company’s on-balance sheet interim loan portfolio at December 31, 2014 or 2013.

PROVISION FOR CREDIT LOSSES associated with the at risk servicing portfolio for 2014 was $1.8 million, a 102% increase from the prior year provision of $0.9 million. For the fourth quarter 2014, the provision for credit losses associated with the at risk servicing portfolio was $0.5 million compared to a net recovery of $0.1 million for the fourth quarter 2013.

The on-balance sheet INTERIM LOAN PORTFOLIO, which is comprised of loans for which we have full risk of loss, was $225.3 million at December 31, 2014. Although all of our interim loans are current and performing as expected as of December 31, 2014, the Company provided a general reserve for potential losses of $0.9 million, representing under 1% of the unpaid principal balance, compared to $0.4 million as of December 31, 2013.

NET WRITE-OFFS for the fourth quarter 2014 were $0.5 million, or less than one basis point of the December 31, 2014 at risk servicing portfolio, compared to $1.0 million for the prior year. During the fourth quarter 2014, one loan for which losses were previously recognized as part of the provision for credit losses from 2012 was settled with Fannie Mae. Net write-offs for 2014 were $5.2 million, or 3 basis points of the December 31, 2014 at risk servicing portfolio, compared to $9.2 million in the prior year. Net write-offs represent the cash settlement of the Company’s guaranty obligations related to losses provided for in prior periods.

PLATFORM GROWTH

Walker & Dunlop acquired the loan origination and servicing portfolio of Johnson Capital Group, Inc (“Johnson Capital”) in the fourth quarter 2014. As part of the acquisition, the Company expanded its national brokerage footprint with the addition of 34 originators in two new offices and seven existing Walker & Dunlop locations. The originators that joined Walker & Dunlop from Johnson Capital contributed $204.0 million in loan originations in the fourth quarter 2014. The acquisition of Johnson Capital and the net new hires during 2014 increased originator headcount from 61 at December 31, 2013 to 102 at December 31, 2014.

Non-GAAP Financial Measures

To supplement the financial statements presented in accordance with United States generally accepted accounting principles (GAAP), the Company presents the following non-GAAP financial measures, each of which excludes certain revenues and expenses that are not reflective of our ongoing operations: adjusted net income, adjusted diluted earnings per share, adjusted total expenses, adjusted income from operations and adjusted operating margin. These supplemental measures exclude acquisition, integration and amortization costs related specifically to the CWCapital acquisition, severance and lease restructuring charges related to our fourth quarter 2013 expense reduction efforts, early extinguishment of our term loan facility, and revenues from the termination fee related to the transfer of servicing for a portion of the Fannie Mae small loan portfolio.

In addition, the Company presents adjusted EBITDA which 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, GAAP net income. Adjusted EBITDA represents GAAP net income before income taxes, interest expense on our term

5

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. In addition, adjusted EBITDA further excludes the impact of the aforementioned acquisition, integration and restructuring costs, severance and lease restructuring charges related to our fourth quarter 2013 expense reduction efforts, early extinguishment of our term loan facility, and revenues from the termination fee related to the transfer of servicing for a portion of the Fannie Mae small loan portfolio that are not considered part of our ongoing operations. 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.

The Company believes that adjusted EBITDA, adjusted net income, adjusted diluted earnings per share, adjusted total expenses, adjusted income from operations and adjusted operating margin facilitate a review of the comparability of the Company’s operating performance on a period-to-period basis because such costs and revenues are not, in our view, related to the Company’s ongoing operational performance. We use these non-GAAP measures 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 these measures 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 these non-GAAP measures, when read in conjunction with the Company’s GAAP financials, provide useful information to investors by offering:

These non-GAAP measures are not in accordance with or an alternative for GAAP, and may be different from non-GAAP measures used by other companies. We believe that these non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP measures. We compensate for the limitations of non-GAAP financial measures by relying upon GAAP results to gain a complete picture of our performance.

For more information on these non-GAAP financial measures, refer to the section of this press release below titled “Adjusted Financial Metrics 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.
