OraSure Announces 2015 Third Quarter Financial Results

BETHLEHEM, PA – November 4, 2015 – (Globe Newswire) – OraSure Technologies, Inc. (NASDAQ: OSUR), a leader in point-of-care diagnostic tests and specimen collection devices, today announced its consolidated financial results for the three and nine months ended September 30, 2015.

Financial Highlights

“We are pleased with the Company’s financial results for the third quarter,” said Douglas A. Michels, President and CEO of OraSure Technologies. “Our molecular collection systems segment continued its solid performance with a second consecutive quarter of more than $7 million in revenues. In addition, our HCV business once again generated strong quarterly growth on both a year-over-year basis and sequentially when compared to the second quarter of this year. We expect these businesses will continue to be the primary growth drivers for our Company.”

Financial Results

Consolidated net product revenues for the third quarter and first nine months of 2015 increased 5% and 3% over the comparable periods of 2014, respectively, primarily as a result of higher sales of the Company’s molecular collection systems, OraQuick^® HCV and Intercept^® products. These increases were partially offset by lower OraQuick^® professional HIV product sales in both periods and lower cryosurgical systems sales during the nine-month period.

Consolidated other revenues for the third quarter and first nine months of 2015 were $4.1 million and $11.5 million, respectively. Other revenues in the current quarter included $3.4 million of exclusivity payments recognized under the Company’s HCV co-promotion agreement with AbbVie and $750,000 of Ebola-related funding received from the U.S. Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response’s Biomedical Advanced Research and Development Authority (“BARDA”). Other revenue in the first nine months of 2015 included $10.0 million of AbbVie exclusivity payments and $1.5 million in BARDA funding. Other revenues in the third quarter and first nine months of 2014 included $3.4 million and $4.2 million of AbbVie exclusivity payments, respectively.

Consolidated gross margin for the three and nine months ended September 30, 2015 was 69% and 67%, respectively. Consolidated gross margin for the three and

nine months ended September 30, 2014 was 67% and 63%, respectively. Gross margin for the current quarter increased primarily due to a reduction in royalty expense and the increase in other revenues, partially offset by the impact of a less favorable product mix. Gross margin for the nine-month period improved largely due to the $7.4 million increase in other revenues and a reduction in royalty expense. Other revenues contributed approximately 500 and 200 basis points to gross margin for the nine months ended September 30, 2015 and 2014, respectively.

Consolidated operating expenses increased to $19.1 million during the third quarter of 2015 compared to $17.8 million in the comparable period of 2014. This increase was largely due to costs associated with the AbbVie co-promotion agreement along with higher legal costs, partially offset by lower research and development expenses and a favorable change in the exchange rate between the Canadian and U.S. dollar.

For the nine months ended September 30, 2015, consolidated operating expenses were $54.4 million, an increase from the $50.9 million reported for the nine months ended September 30, 2014. This increase was largely due to the absence of the $5.5 million Roche termination payment received in 2014, higher legal costs, increased research and development expenses, and costs associated with the AbbVie co-promotion agreement, partially offset by lower promotional expenses for the Company’s OraQuick^® In-Home HIV test and the impact of a favorable change in exchange rates. Promotional expenses for the OraQuick^® In-Home HIV test were $1.3 million and $7.7 million for the first nine months of 2015 and 2014, respectively.

The Company’s cash and short-term investment balance totaled $108.2 million at September 30, 2015 compared to $97.9 million at December 31, 2014. Working capital was $112.1 million at September 30, 2015 compared to $104.8 million at December 31, 2014. For the nine months ended September 30, 2015, the Company generated $15.1 million in cash from operations.

Fourth Quarter 2015 Outlook

The Company expects consolidated net revenues to range from $29.5 to $30.0 million and is projecting a consolidated net income of between $0.03 and $0.04 per share.
