MYRIAD GENETICS REPORTS FINANCIAL RESULTS FOR

FISCAL 2010 SECOND QUARTER

- Revenue Grows 11%; Net Income Rises 67% Compared with Prior Year Period -

Salt Lake City, February 2, 2010 — Myriad Genetics, Inc. (Nasdaq: MYGN) today reported financial results for its second fiscal quarter and the six-month period ended December 31, 2009.

Second Fiscal Quarter Financial Results

Revenues rose 11% to $92.8 million for the three-month period ended December 31, 2009, from $84.0 million in the same three months of the prior fiscal year and increased 9% on a sequential quarterly basis. Myriad attributes this growth primarily to increased sales and marketing efforts that improved physician acceptance and adoption of the Company’s products.

Net income for the second quarter of fiscal 2010 rose 67% to $35.4 million, or $0.36 per diluted share, compared with $21.2 million, or $0.22 per diluted share, in the same quarter of the prior year, which included a loss of $15.6 million from discontinued operations related to the Company’s former research and pharmaceutical businesses. Continued efficiency improvements in the Company’s molecular diagnostics laboratory, including an increase in gross profit margin from 87% to 88% in the second quarter of fiscal 2010, compared to the first quarter of fiscal 2010 was an important contributor to the Company’s profitability.

“Improvements in the overall economy as well as recent Company-specific strategic initiatives, allowed us to generate solid year-over-year revenue growth and a return to sequential revenue growth,” said Peter Meldrum, President and Chief Executive Officer of Myriad Genetics, Inc. “I am also pleased to report that we will announce the launch of our eighth molecular diagnostic product at Myriad’s Investor Day in New York City on March 3, 2010.”

Research and development expense was $5.1 million for the three months ended December 31, 2009, compared with $4.6 million for the same period in the prior fiscal year. This 11% increase was primarily due to additional R&D expenditures in support of the Company’s internal product pipeline and in preparation for the expected launch of two new molecular diagnostic products in this calendar year. The Company plans to announce the launch of its ninth molecular diagnostic product for the genetic predisposition to pancreatic cancer during the second half of 2010.

Selling, general and administrative expense for the second quarter of fiscal 2010 was $42.1 million, compared with $35.0 million for the same quarter of the prior fiscal year, representing an increase of 20%. This increase was primarily attributable to costs associated with increased revenue growth, such as expansion of the Company’s sales force to 300 from 250 persons, support of its direct-to-consumer marketing campaigns in the Mid West and South regions, and expansion of its physicians speakers programs. The Company believes these investments are important for future revenue growth.

During the second quarter of fiscal 2010, days sales outstanding for Myriad’s accounts receivable was 47 days. The Company believes that its accounts receivable are of high quality, with a modest bad debt expense of 5% of revenues.

Six-Month Financial Results

For the first six months of fiscal 2010, revenues increased 16% to $177.9 million from $153.9 million in the same period last year. Net income for the six months ended December 31, 2009, was $65.8 million, or $0.66 per diluted share, compared with net income of $35.7 million, or $0.37 per diluted share, for the same period of the prior year, which included a loss of $25.6 million from discontinued operations.

The Company continues to maintain a strong balance sheet, with $457.6 million in cash, cash equivalents and marketable investment securities at December 31, 2009, compared with $392.2 million at June 30, 2009. This 17% cash increase reflects the Company’s strong cash generating capability, which contributed more than $40 million during the second fiscal quarter. The Company has no debt or convertible securities.
