“Foundation Medicine achieved significant strategic and operational advances across all aspects of our molecular information business in 2015 that position the Company for continued growth in 2016 and beyond,” stated Michael J. Pellini, M.D., chief executive officer of Foundation Medicine. “Specifically, we grew our commercial business and our molecular information platform to more than 68,000 cases, expanded our biopharmaceutical business both in terms of the number of partners and revenue, strengthened our leadership position through our collaboration with Roche, and secured our first national payer contract for metastatic non-small cell lung cancer with United Healthcare.”

2015 Enterprise Highlights:

• Completed a strategic transaction with Roche to further advance Foundation Medicine's market-leading position in molecular information and expand access to the company's products globally.
• Grew biopharmaceutical revenue by approximately 80% in 2015 and added new molecular information and companion diagnostic collaborations with Roche, H3 Biomedicine, Mirati Therapeutics, and several other partners.
• Improved patient access to comprehensive genomic profiling by signing a national agreement with United Healthcare for FoundationOne® in metastatic non-small cell lung cancer. Additionally, Palmetto GBA, a Medicare Administrative Contractor (MAC), announced a final local coverage determination for comprehensive genomic profiling in a subset of patients with non-small cell lung cancer.
• Expanded its molecular information platform to more than 68,000 cases.
• Advanced its circulating tumor DNA (ctDNA) assay program by initiating a large, multi-center clinical study to support the anticipated commercial launch of the assay in 2016. The ctDNA assay was launched to biopharmaceutical partners in 2015, as planned.
• Launched the Precision Medicine Exchange Consortium™ (PMEC) with leading academic medical centers and community oncology networks to advance the integration of molecular information into clinical oncology and accelerate the adoption of precision care.
• Launched decision support tools to help improve utilization of molecular information by oncologists and pathologists, including enhancements to FoundationICE™, such as PatientMatch^TM and the introduction of GeneKit^TM, a genomics solutions portal for pathologists.
• Published 56 peer-reviewed manuscripts in top medical and scientific journals and presented 101 podium talks and posters at scientific and medical meetings.

2016 Outlook

The company expects revenue in 2016 will be in the range of $110 to $120 million and operating expenses will be in the range of $175 and $185 million. The company expects to deliver between 37,000 and 40,000 FoundationOne® and FoundationOne® Heme clinical tests in 2016. The company also expects to expand upon progress made in 2015 with Palmetto and commercial payers and drive additional coverage decisions.

As part of its commitment to providing healthcare practitioners with a full suite of analytically validated genomic profiling assays to support precision medicine in oncology, the company plans to expand its offering of molecular information products with the commercial launch of its ctDNA assay in the first quarter 2016. The assay is being rigorously evaluated as part of an ongoing, multi-center study to identify patients who are most likely to benefit from liquid-based genomic profiling. The study will also provide the analytic validation mandated for clinical use of a commercial ctDNA assay. To further support the commercial launch of the assay, the laboratory will have expansion capability for a QSR-compliant version of the assay to support companion diagnostics for potential FDA approval.

Complete quarterly and full year financial results will be announced during the company’s fourth quarter and fiscal year 2015 financial results conference call in February. This press release contains certain unaudited financial results for the company. These unaudited results could change as a result of further review by the company’s management and its independent auditors.
