REDWOOD CITY, Calif., Nov. 3, 2015 -- Genomic Health, Inc. (GHDX) today reported financial results and business progress for the quarter ended September 30, 2015.

Revenue was $73.6 million in the third quarter of 2015 compared with $69.1 million for the third quarter of 2014, an increase of 6 percent. On a constant currency basis, revenue increased 8 percent compared with the same period in the prior year.

U.S. revenue was $63.1 million in the third quarter of 2015, an increase of 9 percent compared with the same period in the prior year. International revenue was $10.5 million in the third quarter of 2015 compared with $11.3 million a year ago. International revenue was impacted negatively by $0.9 million from foreign exchange rate differences due to the stronger dollar.

More than 27,820 Oncotype DX^® test results were delivered in the third quarter of 2015, compared with more than 23,700 test results delivered in the same period in 2014, an increase of 17 percent. International test results delivered grew 30 percent compared with the prior year and represented approximately 22 percent of total test volume in the third quarter of 2015.

"In the third quarter, we delivered the highest level of test growth in two years and nearly double-digit revenue growth in the U.S.," said Kim Popovits, chairman of the board, chief executive officer and president of Genomic Health. "With the recently published TAILORx prospective outcomes data supporting our invasive breast cancer test, Medicare coverage of our prostate cancer test, and momentum for both our international and DCIS breast cancer business, we expect to deliver double-digit test and revenue growth in the fourth quarter."

Operating loss for the third quarter narrowed to $5.4 million compared with $5.8 million for the third quarter of 2014. Net loss was $11.8 million for the third quarter of 2015 and includes a $6.2 million tax expense in the quarter resulting from a change in fair value of the company's investment in a marketable security. Basic and diluted net loss per share was $0.36 for the third quarter of 2015 compared with basic and diluted net loss per share of $0.20 for the same period in 2014.

Nine Months Ended September 30, 2015, Financial Results

Revenue for the nine months ended September 30, 2015, was $212.3 million compared with $206.6 million for the nine months ended September 30, 2014. On a constant currency basis, revenue increased 4 percent compared with the same period in the prior year.

Operating loss was $30.9 million for the nine months ended September 30, 2015, compared with an operating loss of $17.6 million for the nine months ended September 30, 2014. The operating loss for the nine months ended September 30, 2015 includes a non-recurring first quarter charge of $5.5 million in R&D associated with the wind-down of a breast cancer collaboration and continued planned investments in prostate and international opportunities.

Net loss was $30.6 million for the nine months ended September 30, 2015, compared with a net loss of $18.3 million for the nine months ended September 30, 2014.

Cash and cash equivalents and short-term marketable securities at September 30, 2015, were $98.0 million including the fair value of the company's investment in a marketable security of $15.9 million, compared with $103.7 million at December 31, 2014.

"Medicare coverage for our Oncotype DX prostate cancer test became effective October 13, which will lead to revenue in the fourth quarter from prostate cancer tests delivered to eligible Medicare patients, a key milestone for generating consistent double-digit revenue growth and moving toward profitability," said Brad Cole, chief operating officer and chief financial officer of Genomic Health.

Recent Business Highlights

Oncotype DX Commercial Progress

• Palmetto GBA, a Medicare Administrative Contractor (MAC) that assesses molecular diagnostic technologies, initiated reimbursement coverage of the Oncotype DX prostate cancer test for qualified Medicare patients throughout the United States effective October 13, 2015.
• Expanded coverage of the Oncotype DX breast cancer test for patients with 1-3 positive nodes to include 5 million additional lives through a new policy with Highmark Blue Cross and Blue Shield.
• The National Institutes of Health's (NIH) Genetic Testing Registry, a free online resource to provide physicians, researchers and patients with detailed and accurate information about genetic and genomic tests, now includes information on the Oncotype DX DCIS Score™, Genomic Prostate Score and colon cancer Recurrence Score^®.

Pipeline, Presentations and Publications

• The New England Journal of Medicine published the first prospective outcomes results from the Trial Assigning IndividuaLized Options for Treatment (Rx), or TAILORx, a large multi-center trial sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health, and led by the ECOG-ACRIN Cancer Research Group, demonstrating that trial participants with low Oncotype DX Recurrence Scores of 10 or less who received hormonal therapy alone without chemotherapy had excellent outcomes, with less than a one percent chance of distant recurrence at five years. The results were also presented in a Presidential Session at the 2015 European Cancer Congress (ECC2015) in Vienna.
• Two large international Oncotype DX clinical outcomes studies presented at ECC2015 provided additional prospective data reinforcing the ability of Oncotype DX to accurately predict clinical outcomes in early-stage breast cancer patients.
• The Japan Breast Cancer Society updated its Breast Cancer Management Guidelines, recommending Oncotype DX as the only test for use in determining chemotherapy treatment in hormone receptor-positive, early-stage breast cancer.
• Presented additional positive results from the second large, independent clinical validation study of the Oncotype DX DCIS Score at the American Society for Therapeutic Radiology and Oncology annual meeting. Results reconfirm that the test is a strong independent predictor of local recurrence, which could be either invasive breast cancer or DCIS, in patients with DCIS.
• Received acceptance to present eight studies at the 2015 CTRC-AACR San Antonio Breast Cancer Symposium (SABCS), including a poster presentation on outcomes in patients using the Oncotype DX invasive breast cancer test through a collaboration with The Surveillance, Epidemiology, and End Results (SEER) registry.
