Myriad Genetics Reports Results for Second Quarter of Fiscal 2006

Record Revenues and Lower Loss Highlight Quarter

SALT LAKE CITY, February 7, 2006 – Myriad Genetics, Inc. (Nasdaq: MYGN) (www.myriad.com) today reported financial results for the second quarter of fiscal 2006 and the six months ended December 31, 2005.

For the second fiscal quarter of 2006, total revenues grew to a record $27.3 million from $19.6 million in the same quarter of fiscal 2005. The net loss was reduced to $8.0 million from $10.0 million in the second quarter last year and the net loss per share was $0.22, compared with $0.33 in the same quarter of fiscal 2005.

Predictive medicine revenues increased $5.9 million from $17.5 million for the same quarter last year. Compared with the first quarter of fiscal 2006, predictive medicine revenues were up 9%. This significant increase in predictive medicine revenues reflects strong customer demand for Myriad's predictive medicine products due in part, we believe, to the demonstrated clinical utility of the test and the value to patients of using Myriad's BRACAnalysis®, COLARIS®, and MELARIS® predictive medicine products. For the first six months of this year, predictive medicine revenues were $44.9 million, an increase of 41% from $32.0 million during the same period last year.

Research revenues increased 87% from $2.1 million for the second quarter of fiscal 2005 to $3.9 million for the second quarter of fiscal 2006. Despite this increase, the Company continues to reduce the emphasis on external research collaborations in favor of its own in-house drug development programs. Total revenues in the second quarter of 2006 increased to $27.3 million, from $19.6 million for the same period of fiscal 2005, an increase of 39% year-to-year. Compared with the first quarter of fiscal 2006, total revenues increased by $2.2 million, or 9%.

Net loss for the second quarter of fiscal 2006 was $8.0 million or $0.22 per share, compared with $10.0 million, or $0.33 per share, for the same quarter of fiscal 2005. This approximately $2.0 million, or 20% reduction in net loss is in large part the result of an increased contribution from our profitable predictive medicine business. As of December 31, 2005, Myriad had approximately $235 million in cash, cash equivalents and marketable investment securities. The Company has no debt or convertible securities.

"We are pleased to report the continued growth in our predictive medicine business and the excellent progress in advancing our drug candidates through the regulatory process," commented Peter Meldrum, President and CEO of Myriad Genetics, Inc. "Second quarter was particularly strong, with record revenues, strong profit margins and a significant reduction in our net loss."

Research and development expense was $19.0 million for the quarter, compared to $14.5 million for research and development in the same quarter of the prior year. This 31% increase in research and development expense includes the ongoing investment necessary to the continuation of six clinical trials and the advancement of several promising late-stage preclinical drug compounds toward IND submission. The human clinical trials consist of a Phase 3 study of Flurizan in Alzheimer's disease, a 12-month follow-on study to the Phase 2 Alzheimer's disease trial, a Phase 2b trial of MPC-7869 in prostate cancer, two Phase 1 trials with MPC-6827 in metastatic cancer and independently in brain cancer and a Phase 1 study of MPC-2130 in blood cancers and advanced metastatic tumors.

An update on several of Myriad's clinical trials, including their current status as well as any recent or anticipated protocol amendments, will be provided by Company management during the conference call detailed below.
