Financial Highlights

Key Business Highlights

“2015 is off to a great start with many significant achievements,” said Noah Breslow, chief executive officer, OnDeck. “Not only did OnDeck continue to deepen our market penetration with an expanded product offering in Canada, but we also announced notable strategic partnerships and the company’s expansion into Australia. These milestones reflect our commitment to continual innovation and solidify our position as a market leader.”

“OnDeck delivered another strong financial performance amid a period of investment,” said Howard Katzenberg, chief financial officer, OnDeck. “We generated record originations volume and record gross revenue, while also maintaining the credit quality of our portfolio and passing along savings to our customers in the form of lower average APRs.”

Review of Financial Results for the First Quarter of 2015

Originations grew to $416 million during the first quarter of 2015, up 83% from the comparable prior year period. Originations growth reflected strength in all three distribution channels, particularly in the direct and strategic partner channels.

Gross revenue increased to $56.5 million during the first quarter of 2015, up 98% from the comparable prior year period. The increase in gross revenue was primarily due to growth in originations as well as increased volume sold through the OnDeck Marketplace during the first quarter of 2015 compared to the prior year period. The effective interest yield for the first quarter of 2015 was 36.7%, down from 41.2% in the comparable prior year period, reflecting the continued mix shift to lower cost distribution channels, an increase in average term length over the period and OnDeck’s continuing efforts to lower pricing for customers as it achieves cost efficiencies. Reflecting these trends, the average APR of loans originated in the first quarter was 49.3%, a decline from 59.9% in the prior year period.

Net revenue increased to $28.3 million during the first quarter of 2015, up 286% from the comparable prior year period. Net revenue margin increased to 50.1% during the first quarter of 2015 from 25.7% in the prior year period, principally due to a lower Cost of Funds Rate and a lower Provision Rate.

The Cost of Funds Rate during the first quarter of 2015 declined to 5.1% of Average Funding Debt Outstanding, down from 9.3% in the comparable prior year period. The improvement was primarily the result of the company’s continued shift to lower-cost funding sources, including the company’s securitization that closed in the second quarter of 2014.

Provision for loan losses during the first quarter of 2015 increased to $23.1 million, up from $16.6 million during the year ago period, primarily as a result of the growth in originations. The Provision Rate in the first quarter of 2015 was 7.2%, compared to 8.4% in the comparable prior year period.

Operating expenses were $33.5 million during the first quarter of 2015, up 135% over the comparable prior year period as OnDeck increased investment in direct marketing, expanded its technology and analytics teams to support growth and incurred additional general and administrative expenses related to operating as a public company. Operating expense as a percent of gross revenue for the first quarter of 2015 was 59.4%, up from 50.0% during the year ago period, reflecting these investments.

Adjusted EBITDA was a loss of $1.8 million in the quarter, an improvement from a loss of $5.8 million in the comparable prior year period.

Adjusted Net Loss improved to a loss of $3.3 million, or $0.05 per basic share, for the quarter versus a loss of $6.9 million, or $1.46 per basic share, in the comparable prior year period.

OnDeck had a GAAP net loss of $5.3 million, or $0.08 per basic share, for the quarter which compares to a GAAP net loss of $13.7 million, or $3.47 per basic share, in the comparable prior year period.
