OraSure Announces 2017 Third Quarter Financial Results

BETHLEHEM, PA – November 1, 2017 – (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, 2017.

Financial Highlights

“We are very pleased with the Company’s third quarter financial results,” said Douglas A. Michels, President and Chief Executive Officer of OraSure Technologies. “Sales of our molecular collections products during the quarter were particularly strong and our infectious disease business experienced strong growth compared to the prior year quarter. We continue to deliver on our strategic growth priorities and we expect our strong performance to continue into the fourth quarter.”

Financial Results

Consolidated net product revenues for the third quarter of 2017 increased 62% over the comparable period of 2016. Consolidated net product revenues for the first nine months of 2017 increased 43% over the comparable period of 2016. These increases were primarily the result of higher sales of the Company’s molecular collections and OraQuick^® HCV products and higher international sales of the OraQuick^® HIV self-test, partially offset by lower domestic sales of the Company’s professional OraQuick^® HIV product and lower cryosurgical product sales. Product revenues associated with the 2017 sales of the OraQuick^® HIV self-test include $458,000 of support payments associated with the charitable support agreement with the Bill and Melinda Gates Foundation (“Gates Foundation”).

Consolidated other revenues for the third quarter and first nine months of 2017 were $1.2 million and $3.3 million, respectively. This compares to consolidated other revenues for the third quarter and first nine months of 2016 of $6.8 million and $14.4 million, respectively. Other revenues in the third quarter of 2017 included $939,000 of funding received from the U.S. Biomedical Advanced Research Development Authority (“BARDA”) and $218,000 in cost reimbursement under the Company’s charitable support agreement with the Gates Foundation. Other revenues in the third quarter of 2016 included $676,000 of BARDA funding and

$6.1 million of exclusivity revenues recognized under the Company’s HCV co-promotion agreement with AbbVie, which terminated on December 31, 2016. Other revenues in the first nine months of 2017 included $3.1 million of BARDA funding and $218,000 of cost reimbursement under the Gates Foundation agreement. Other revenues in the first nine months of 2016 included $1.6 million of BARDA funding and $12.8 million of AbbVie exclusivity revenues.

Consolidated gross margin was 58% and 61% for the three and nine months ended September 30, 2017, respectively. Consolidated gross margin for the three and nine months ended September 30, 2016 was 70% and 69%, respectively. Gross margin for the current quarter and the first nine months of 2017 decreased primarily due to the absence of AbbVie exclusivity revenues during these periods, an increase in lower margin product sales, and higher scrap and spoilage costs.

Consolidated operating expenses increased to $17.3 million during the third quarter of 2017 compared to $16.5 million in the third quarter of 2016. For the nine months ended September 30, 2017, consolidated operating expenses were $40.4 million, a $10.5 million decrease from the $50.9 million reported for the nine months ended September 30, 2016. The quarterly increase was largely due to higher sales and marketing expenses resulting from higher staffing costs, higher external commissions to be paid to certain international distributors, and an increase in our allowance for doubtful accounts related to a genomics customer. The reduction in the nine-month period was primarily due to a $12.5 million gain on a litigation settlement reported earlier this year, the absence of costs associated with the AbbVie HCV co-promotion agreement, and lower legal fees partially offset by higher staffing costs.

Operating income increased 19% to $7.3 million in the third quarter of 2017 compared to $6.1 million in the third quarter of 2016. Operating income for the nine months ended September 30, 2017 was $30.1 million, a 128% increase over the comparable period in 2016.

The Company’s cash and investment balance totaled $180.3 million at September 30, 2017, compared to $120.9 million at December 31, 2016. Working capital was $182.7 million at September 30, 2017, compared to $139.1 million at December 31, 2016. For the nine months ended September 30, 2017, the Company generated $30.4 million in cash from operations.

Fourth Quarter 2017 Outlook

The Company expects consolidated net revenues to range from $45 million to $46 million and is projecting consolidated net income of $0.08 to $0.09 per share for the fourth quarter of 2017.
