Business Highlights

• On Sept. 3, 2013, the Myriad myRisk™ Hereditary Cancer test was launched to thought leaders in the United States. Myriad presented data at the Collaborative Group of the Americas on Inherited Colorectal Cancer demonstrating that myRisk Hereditary Cancer significantly improved the sensitivity of colon cancer risk assessment by detecting 60 percent more deleterious mutations in 1,133 patients who met clinical criteria for hereditary colon cancer testing.

• Myriad presented data at the American Society of Human Genetics (ASHG) Annual Meeting demonstrating that myRisk Hereditary Cancer correctly identified 15,877 of 15,878 known mutations when compared to Sanger sequencing, representing an analytical sensitivity of 99.99%.

• On Oct. 29, 2013, the Myriad myPlan™ Lung Cancer test was launched to leading oncologists throughout the United States. Myriad published a peer-reviewed clinical study on myPlan Lung Cancer in Clinical Cancer Research demonstrating that the test was a highly significant predictor of death in patients with early-stage lung cancer.

• Myriad also showcased data on myPlan Lung Cancer at the International Association for the Study of Lung Cancer Annual Meeting showing that the test accurately predicted a lung cancer patient’s risk of dying from the disease. Patients with a high-risk myPlan Lung Cancer score had approximately twice the number of lung-cancer deaths over a five year period compared to patients with a low-risk score.

• Study results on the Myriad myPath™ Melanoma test were presented at the American Society of Dermatopathology’s Annual Meeting demonstrating that it was highly effective in differentiating melanoma from benign nevi. myPath Melanoma test achieved an 89 percent sensitivity and 93 percent specificity across 464 skin biopsy lesions, which included 254 melanomas across all major subtypes.

• Myriad announced expanded collaborations with BioMarin, Tesaro, and AstraZeneca to advance their PARP inhibitors through Phase 3 clinical trials with the U.S. Food and Drug Administration.

New $300 Million Share Repurchase Program

Myriad has exhausted its current $200 million stock repurchase authorization. Since 2010, the Company has repurchased $700 million of stock representing approximately 30 percent of the total outstanding shares. Myriad announced today that its Board of Directors authorized a new $300 million stock repurchase authorization, expanding the total share repurchase program to $1 billion.

“This decision further exemplifies Myriad’s commitment to return cash to shareholders,” said James Evans, Chief Financial Officer of Myriad, “We will continue to opportunistically repurchase shares at valuation thresholds that we believe are not reflective of the long-term value of the Company.”

Repurchases through the $300 million authorization will be made via open market or privately negotiated purchases as determined by the Company’s management. The amount and timing of stock repurchases will depend on business and market conditions, stock price, trading restrictions, acquisition activity, and other factors.

Increased Fiscal Year 2014 Outlook

Myriad is raising its revenue expectations for fiscal year 2014. The Company is forecasting revenues of $700 to $715 million, compared to previous guidance of $690 to $710 million. This new guidance represents 14 to 17 percent revenue growth when compared to the prior fiscal year. Myriad is also increasing its diluted earnings per share guidance for fiscal year 2014. The Company is projecting diluted earnings per share of $1.92 to $1.97 compared to previous guidance of $1.87 to $1.94. This new guidance represents 9 to 12 percent EPS growth.
