BETHLEHEM, Pa. – OraSure Technologies, Inc. announced today that it will acquire privately-held, DNA Genotek Inc., a leading provider of oral fluid sample collection, stabilization and preparation products for molecular diagnostic applications, for approximately US $53 million in cash, subject to certain adjustments. The transaction is anticipated to close in the third quarter of this year. DNA Genotek generated approximately US $14.0 million in total revenues for the year ended December 31, 2010.

The acquisition of DNA Genotek strengthens OraSure’s leadership in oral fluid diagnostics, by providing OraSure with a complementary portfolio of products that enable easy and reliable collection, stabilization, transportation and storage of high quality nucleic acid (DNA and RNA) samples. These samples can then be used for a wide range of diagnostic and research applications.

“We are delighted to have the opportunity to acquire DNA Genotek which is a recognized leader in the nucleic acid collection market and fits soundly with OraSure’s strategic goals and objectives. We targeted entry into the US $4 billion molecular diagnostics market given the magnitude and rapid growth profile of the segment,” said Douglas A. Michels, President and CEO of OraSure Technologies. “Our companies share a common capability and passion to develop best-in-class oral fluid-based solutions. Since 2004, DNA Genotek has posted impressive financial revenue growth and profitability and we fully expect that solid performance to continue.”

“Joining forces with OraSure at this time will be instrumental in taking DNA Genotek to the next level. Together we will have the ability to capitalize more quickly on the tremendous opportunity in the rapidly growing molecular research and clinical diagnostic markets,” said Ian Curry, President and CEO of DNA Genotek Inc. “Our companies both endeavor to provide high-quality, non-invasive sample collection devices and the combination of our resources will significantly enhance our ability to deliver industry leading solutions to our customers. The two organizations are complementary from a technology and people perspective. We have been impressed with the leadership at OraSure and look forward to working closely with them.”

DNA Genotek has revolutionized the nucleic acid (DNA and RNA) collection market with products that provide substantial advantages over traditional methods such as blood or buccal swabs, including the reliable collection of high quality genetic samples using a simple, non-invasive method and the ability to transport and store collected samples for extended periods at ambient temperatures.
