Results for the Second Quarter Ended June 30, 2017

The Company’s revenues grew 16.7% to $137.4 million for the second quarter of 2017, which represents an increase of $19.7 million compared to the second quarter of 2016. The Company generated operating income of $19.4 million during the second quarter of 2017, an increase of $1.8 million, or 10.3% when compared to the second quarter of 2016. This increase in operating income is primarily due to the 16.7% increase in revenues which was partially offset by (i) increases in the Company’s compensation-related costs and other expenses associated with the net growth in headcount of 81 associates during the last twelve months, (ii) an increase in non-cash stock compensation and (iii) increases in other operating expenses due to the growth in transactional activity and the increase in headcount.

Interest and other income, net, grew 49.2% to $13.0 million in the second quarter of 2017, compared to $8.7 million in the second quarter of 2016. This increase is primarily a result of higher income from the valuation of the Company’s mortgage servicing rights.

The Company reported net income for the quarter ended June 30, 2017 of $19.5 million, an increase of approximately $3.6 million, or 22.8%, when compared to net income of $15.8 million for the quarter ended June 30, 2016. For the quarter ended June 30, 2017, net income per diluted share was $0.49 compared to $0.41 for the second quarter of 2016.

Adjusted EBITDA (a non-GAAP measure whose reconciliation to net income can be found within this release) for the second quarter of 2017 grew 17.4% to $32.9 million, compared to $28.0 million in the second quarter of 2016. The Adjusted EBITDA margin for the second quarter of 2017 was 23.9%, a 10 basis point increase compared to the Adjusted EBITDA margin of 23.8% in the second quarter of 2016.

Results for the Six Months Ended June 30, 2017

The Company reported revenues of $276.2 million for the six months ended June 30, 2017, which represents an increase of $41.0 million, or 17.4% compared to revenues for the first six months of 2016 of $235.2 million. The Company generated operating income of $40.2 million during the first half of 2017, an increase of $5.8 million, or 17.0% when compared to operating income of $34.3 million for the first half of 2016. This increase in operating income is primarily due to the 17.4% increase in revenues which was partially offset by (i) increases in the Company’s compensation-related costs and expenses associated with

the net growth in headcount of 81 associates during the last twelve months, (ii) an increase in non-cash stock compensation and (iii) increases in other operating expenses due to the growth in transactional activity and the increase in headcount.

Interest and other income, net, totaled $23.8 million for the six months ended June 30, 2017 compared to $15.1 million for the six months ended June 30, 2016. This increase is primarily a result of higher income from the valuation of the Company’s mortgage servicing rights.

The Company reported net income for the six month period ended June 30, 2017 of $39.1 million, an increase of approximately $9.4 million, or 31.6%, when compared to net income of $29.7 million for the six month period ended June 30, 2016. For the six month period ended June 30, 2017, net income per diluted share was $0.99, or a 28.6% increase when compared to $0.77 for the six month period ended June 30, 2016.

Adjusted EBITDA for the six month period ended June 30, 2017 was $65.3 million, which represents an increase of $12.6 million, or 23.9%, when compared to $52.7 million in the comparable period in 2016. This increase in Adjusted EBITDA is primarily attributable to the increase in operating income. The Adjusted EBITDA margin for the six month period ended June 30, 2017 was 23.6%, a 120 basis point increase, compared to an Adjusted EBITDA margin of 22.4% in the comparable period in 2016.

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 and the inherent value of servicing rights, which are non-cash income amounts 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 to be 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.
