Second Quarter 2015 Financial Results

Revenue for the second quarter of 2015 was $14.3 million, representing 21% growth over the second quarter 2014 revenue of $11.8 million. On a constant currency basis, revenue growth was 29% versus the prior year period.

2015 second quarter product revenue was $6.6 million representing a 12% increase from product revenue of $5.9 million in the second quarter of 2014. The increase in product revenue was primarily attributable to volume growth in both Asia and Europe & ROW. Service revenue for the second quarter of 2015 was $7.7 million, up 29% from the 2014 second quarter of $5.9 million. The increase in service revenue was primarily driven by increased volume, specifically in the institutional and physicians’ office segments, and increased average selling prices in the U.S. market.

United States revenue was $7.3 million in the second quarter of 2015 representing 33% growth over the same period's revenue of $5.5 million in the prior year. Growth was driven primarily by an increased number of customers and increased volume from existing customers.

Europe & ROW revenue was $1.9 million in the second quarter of 2015 representing a 6% increase compared to 2014 second quarter revenue of $1.8 million. On a constant currency basis, Europe & ROW grew 21% versus the second quarter of 2014, due partially to quarter to quarter volatility in the timing of orders.

Asia revenue was $5.1 million in the second quarter of 2015 representing 12% growth over the 2014 second quarter revenue of $4.5 million. On a constant currency basis, Asia grew 27% versus the second quarter of 2014. The increase was driven by continued strong growth in both China and Japan.

Gross profit for the second quarter of 2015 was $7.8 million, an increase of $2.0 million over gross profit of $5.8 million in the same period of 2014. Gross margin was 54.4%, an increase of 5.2 percentage points from the gross margin of 49.2% in the second quarter of 2014 primarily due to operational efficiencies associated with increased volume and reduced kit costs, partially offset by the impact of foreign currency exchange rate changes and increased share-based compensation charges in 2015 compared to 2014.

Operating expenses were $14.4 million in the second quarter of 2015, an increase of $2.6 million compared to $11.8 million in the same period last year. The increase in operating expenses was primarily due to headcount increases related to both research and development and sales and marketing, as well as increased costs from clinical studies performed during the quarter.

EBITDA for the second quarter was $(6.8) million compared to $(5.8) million in the second quarter of 2014. Adjusted EBITDA was $(6.5) million for the second quarter compared to $(4.9) million in the same period in 2014. Both EBITDA and Adjusted EBITDA are non-GAAP measures.

Net loss for the second quarter of 2015 was $7.3 million, or $0.33 per share, compared to $6.2 million, or $0.36 per share, in the second quarter of 2014. Net loss per share was based on 22,245,682 and 17,292,251 weighted average ordinary shares outstanding for the second quarters of 2015 and 2014, respectively. 

Cash and cash equivalents were $90.4 million as of June 30, 2015 compared to $94.0 million as of March 31, 2015.

Business Outlook

We expect to report revenue of between $16.8 and $17.6 million for the third quarter of 2015.

We expect to report full year 2015 revenue of between $61 and $64 million, representing 23%-29% year-over-year growth. We expect revenue to increase 29% to 35% for the year using constant exchange rates.
