Oxford Immunotec Reports First Quarter 2017 Financial Results

OXFORD, United Kingdom and MARLBOROUGH, Mass., May 2, 2017 (GLOBE NEWSWIRE) -- Oxford Immunotec Global PLC (Nasdaq: OXFD), a global, high-growth diagnostics company focused on developing and commercializing proprietary tests for the management of underserved immune-regulated conditions, today announced first quarter 2017 financial results.

“We are very pleased with our performance during the first quarter as we continued our evolution from a single-product company to a multi-product company,” said Dr. Peter Wrighton-Smith, Chief Executive Officer of Oxford Immunotec. "Our core tuberculosis (TB) business grew in line with our expectations, with strong growth in the U.S. and Europe & ROW markets during the first quarter, and we saw a strong contribution from our newly acquired tick-borne disease franchise. As we move forward through the year, we will continue to focus on driving revenue growth and progressing the company towards profitability.”

⁽¹⁾ Changes in revenue include the impact of changes in foreign currency exchange rates. We use the non-GAAP financial measure "constant currency basis" in our filings to show changes in our revenue without giving effect to period-to-period currency fluctuations. We consider the use of a period over period revenue comparison on a constant currency basis to be helpful to investors, as it provides a revenue growth measure free of positive or negative volatility due to currency fluctuations.

First quarter 2017 Financial Results

Revenue for the first quarter of 2017 was $21.5 million, representing 26% growth over the first quarter 2016 revenue of $17.1 million. On a constant currency basis, revenue growth was 27% versus the prior year period. Tuberculosis revenue for the first quarter of $18.5 million increased 8% over the prior year period.

2017 first quarter product revenue was $8.4 million, representing a 3% increase from product revenue of $8.1 million in the first quarter of 2016. The increase was primarily attributable to Europe & ROW TB growth and the sale of Immunetics tick-borne disease kits, offset by reduced revenue in Asia driven by order timing. Service revenue for the first quarter of 2017 was $13.1 million, up 46% from 2016 first quarter revenue of $9.0 million. The increase in service revenue was primarily driven by increased tuberculosis revenues in the United States as well as revenues from Imugen tick-borne disease services.

United States revenue was $13.5 million in the first quarter of 2017, representing 55% growth over revenue of $8.7 million in the prior year period. The increase was due both to strong organic growth in our core tuberculosis business revenue as well as the additional contribution of our tick-borne disease revenues.

Europe & ROW revenue was $1.8 million in the first quarter of 2017, representing a 12% increase compared to the first quarter of 2016. On a constant currency basis, Europe & ROW increased 22% versus the first quarter of 2016. The increase was primarily due to strong TB growth, particularly in the UK, and sales of Immunetics tick-borne disease kits.

Asia revenue was $6.2 million in the first quarter of 2017, representing a decrease of 9% compared to 2016 first quarter revenue of $6.8 million. On a constant currency basis, Asia declined 8% versus the first quarter of 2016. The decline was due to the timing of orders in China.

Gross profit for the first quarter of 2017 was $11.0 million, an increase of $2.1 million over gross profit of $8.9 million in the same period of 2016. Gross margin was 51.2%, a decrease of 110 basis points from the gross margin of 52.3% in the first quarter of 2016. The first quarter gross margin performance reflects a strong improvement in the underlying TB margins offset by the addition of tick-borne disease products, which carry a lower gross margin.

Operating expenses were $18.0 million in the first quarter of 2017, an increase of $1.9 million compared to $16.1 million in the same period last year. The increase in operating expenses was largely due to the inclusion of operating expenses as a result of the Imugen and Immunetics acquisitions, as well as expenses related to ongoing patent litigation. In addition, in the first quarter we recorded a $2.4 million credit related to the change in fair value of contingent consideration associated with the acquisition of Immunetics.

Net loss for the first quarter of 2017 was $8.1 million, or $0.36 per share, compared to $7.0 million, or $0.32 per share, in the first quarter of 2016. Net loss per share was based on 22,533,531 and 22,284,392 weighted average ordinary shares outstanding for the first quarters of 2017 and 2016, respectively. 

EBITDA for the first quarter was $(6.1) million compared to $(6.4) million in the first quarter of 2016. Adjusted EBITDA was $(7.1) million for the first quarter compared to $(5.8) million in the same period in 2016. Both EBITDA and Adjusted EBITDA are non-GAAP measures.

Business Outlook

We expect to report revenue of between $24.9 and $25.7 million for the second quarter of 2017.

We continue to expect to report full year 2017 revenue of between $102 and $105 million, representing 19% - 22% year-over-year growth. We expect revenue to increase 21% to 24% for the year using constant exchange rates.

Reconciliation of net loss to Adjusted EBITDA ⁽¹⁾

(unaudited)

⁽¹⁾ EBITDA and Adjusted EBITDA are non-GAAP measures that we calculate as net loss, adjusted for the impact of earnings or charges resulting from matters that we consider not to be indicative of our ongoing operations. We believe that these measures provide useful information to investors in understanding and evaluating our operating results in the same manner as our management and Board of Directors. Our presentation of these measures is not made in accordance with U.S. GAAP, and our computation of these measures may vary from others in the industry. Our use of these measures has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP.

The above table presents a reconciliation of net loss, the most comparable U.S. GAAP measure, to EBITDA and Adjusted EBITDA for each of the periods indicated.
