OraSure Announces 2013 Second Quarter Financial Results

BETHLEHEM, PA – August 7, 2013 – (Globe Newswire) – OraSure Technologies, Inc. (NASDAQ: OSUR), a market leader in oral fluid diagnostics, today announced its consolidated financial results for the second quarter and six months ended June 30, 2013.

Financial Highlights

“We are pleased with the Company’s financial results for the second quarter,” said Douglas A. Michels, President and CEO of OraSure Technologies, Inc. “A major contributor to this performance was the record level of revenues reported by our molecular collections subsidiary, DNA Genotek. We are also making good progress in commercializing the OraSure^® In-Home HIV test, as we continue to refine our sales and marketing strategies to maximize the financial opportunity and health benefits offered by this important new product.”

Financial Results

Consolidated net product revenues for the second quarter and six month period increased 8% and 7%, respectively, primarily as a result of the higher sales of the Company’s molecular collection systems and infectious disease testing products. These increases were partially offset by lower sales of the Company’s substance abuse testing, cryosurgical systems and insurance risk assessment products.

Consolidated licensing and product development revenues for the second quarter of 2013 remained relatively flat at $274,000 compared to $277,000 for the second quarter of 2012. Consolidated licensing and product development revenues for the six months ended June 30, 2013 decreased by $1.0 million, primarily due to the absence of a $1.0 million milestone payment received in the first quarter of 2012 under the Company’s HCV collaboration agreement with Merck. No similar payment was received during 2013 because the collaboration agreement with Merck was terminated in November 2012.

Consolidated gross margin for the three and six months ended June 30, 2013 was 60% and 58%, respectively. Consolidated gross margin for the three and six months ended June 30, 2012 was 65%. The current quarter gross margin was negatively impacted by higher royalties paid on sales of the Company’s OraQuick^® HIV products and an unfavorable change in product mix. Gross margin for the current six month period was negatively impacted by the higher royalties, the absence of the $1.0 million HCV milestone payment, the change in product mix and an increase in scrap and spoilage costs as a result of production issues that were identified and corrected in the first quarter of 2013.

Consolidated operating expenses increased to $20.0 million during the second quarter of 2013, from $18.2 million in the comparable period of 2012. For the six months ended June 30, 2013, consolidated operating expenses were $42.7 million, an increase over the $35.6 million reported for the six months ended June 30, 2012. These increases are primarily the result of higher promotional and advertising expenses associated with the Company’s OraQuick^® In-Home HIV test. The current quarter and six month period expenses included $5.4 million and $12.3 million of promotional and advertising costs related to this product compared to $1.6 million and $2.9 million spent in the second quarter and first six months of 2012, respectively.

For the three and six months ended June 30, 2013, the Company recorded a Canadian income tax benefit of $249,000 and $659,000, respectively, associated with the loss before income taxes and certain Canadian research and development and investment tax credits at DNAG.

The Company’s cash balance totaled $77.0 million at June 30, 2013 compared to $87.9 million at December 31, 2012. Working capital was $91.7 million at June 30, 2013 compared to $103.5 million at December 31, 2012. For the six months ended June 30, 2013, the Company used $9.3 million to fund operations, including the advertising and promotional activities related to the OraQuick^® In-Home HIV test. Cash used to fund operations in the second quarter of 2013 was $1.6 million.

Third Quarter 2013 Outlook

The Company expects consolidated net revenues to range from $24.0 to $24.5 million and is projecting a consolidated net loss of approximately $0.09 - $0.10 per share for the third quarter of 2013.
