Consolidated Results for the First Quarter Ended March 31, 2015

The Company reported revenues of $94.3 million for the first quarter of 2015, which represents an increase of $18.2 million, or 24.0% compared to revenues for the first quarter of 2014 of $76.0 million. The Company generated operating income of $11.2 million during the first quarter of 2015, an increase of $7.4 million, or 194.3% when compared to operating income of $3.8 million for the first quarter of 2014. This increase in operating income is primarily due to the 24.0% increase in revenues and was partially offset by (a) increases in the Company’s compensation-related costs and expenses associated with the net growth in headcount of 78 associates during the last twelve months and an increase in contractual performance-based incentives for recruited transaction professionals, and (b) increases in other operating expenses due to the growth in transactional activity and the increase in headcount. These increases were partially offset by a reduction in non-cash stock compensation expense.

Interest and other income, net, totaled $5.5 million in the first quarter of 2015, an increase of $2.6 million, or 90.4%, when compared to $2.9 million in the first quarter of 2014. This increase is primarily a result of additional income recognized upon the initial valuation of the Company’s mortgage servicing rights as well as an increase in securitization and other agency-related income.

The Company reported net income for the quarter ended March 31, 2015 of $9.4 million, an increase of approximately $5.7 million, or 153.8%, when compared to net income of $3.7 million for the quarter ended March 31, 2014. Net income for the quarter ended March 31, 2015 was $0.25 per diluted share compared to $0.10 per diluted share for the first quarter of 2014. The increase of $0.15 per diluted share represents a 150.0% year-over-year improvement.

Adjusted EBITDA (a non-GAAP measure whose reconciliation to net income can be found within this release) for the first quarter of 2015 was $17.8 million, which represents an increase of $6.0 million, or 50.7%, when compared to $11.8 million in the first quarter of 2014. This increase in Adjusted EBITDA is attributable to the increases in operating income as well as securitization and other agency-related income. The Adjusted EBITDA margin for the first quarter of 2015 was 18.9% compared to an Adjusted EBITDA margin of 15.6% in the first quarter of 2014.

Adjusted EBITDA Reconciliation

The Company defines Adjusted EBITDA as net income before (i) interest expense, (ii) income tax expense, (iii) depreciation and amortization, (iv) stock-based compensation expense, which is a non-cash charge, (v) income recognized on the initial recording of mortgage servicing rights that are acquired with no initial consideration, which is also a non-cash income amount that can fluctuate significantly based on the level of mortgage servicing right volumes, and (vi) the increase (decrease) in payable under the tax receivable agreement, which represents changes in a liability recorded on the Company’s consolidated balance sheet determined by the ongoing remeasurement of related deferred tax assets and, therefore, can be income or expense in the Company’s consolidated statement of income in any individual period. 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 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, including the Company’s tax receivable agreement. Note that the Company classifies the interest expense on its warehouse lines of credit as an operating expense and, accordingly, it is not eliminated from net income in determining Adjusted EBITDA. Some of the items that the Company has eliminated from net income in determining Adjusted EBITDA are significant to the Company’s business. For example, (i) interest expense is a necessary element of the Company’s costs and ability to generate revenue because it incurs interest expense related to any outstanding indebtedness, (ii) payment of income taxes is a necessary element of the Company’s costs and (iii) depreciation and amortization are necessary elements of the Company’s costs.

Any measure that eliminates components of the Company’s capital structure and costs associated with the Company’s operations has material limitations as a performance measure. In light of the foregoing limitations, the Company does not rely solely on Adjusted EBITDA as a performance measure and also considers its GAAP results. Adjusted EBITDA is not a measurement of the Company’s financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other measures derived in accordance with 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.
