PART I

Item 1. BUSINESS

Overview

We are one of the largest specialty molecular diagnostic laboratories in the world and since our founding in 1992, have tested over 1.5 million patients. We are headquartered in Salt Lake City, Utah and generated worldwide revenues of approximately $723 million during our fiscal year ended June 30, 2015. We are a leading personalized medicine company dedicated to being a trusted advisor transforming patient lives through pioneering molecular diagnostics. Through our proprietary technologies, we believe we are positioned to identify important disease genes, the proteins they produce, and the biological pathways in which they are involved to better understand the genetic basis of human disease and the role that genes and their related proteins may play in the disease process. We believe that identifying biomarkers (DNA, RNA and proteins) will enable us to develop novel molecular diagnostic tests that can provide important information to solve unmet medical needs.

Our Mission

Our goal is to provide physicians with critical information to guide the healthcare management of their patients by addressing four major questions a patient may have about their healthcare:

• What is the likelihood of my getting a disease?

• Do I have a disease?

• How aggressively should my disease be treated?

• Which therapy will work best to treat my disease?

Over time, we have developed and plan to develop additional products that answer these important questions in six medical specialties: oncology, preventive care, urology, dermatology, autoimmune and neuroscience. We believe that these product channels represent markets where there is a significant opportunity for high-value molecular diagnostic tests to positively impact patient care and drive value for the healthcare system.

Our Business Strategy

Our strategy is focused on executing the following three strategic imperatives:

1. Transition and expand the hereditary cancer market—In fiscal year 2015, approximately 88 percent of our revenue was derived from the sale of products to assess a patient’s risk for hereditary cancer. Given that this is our most important market and that we are the worldwide leader in hereditary cancer testing, we are focused on transitioning this market from single-syndrome testing to a more sensitive panel approach. Additionally, we are continuing to expand market penetration as well as grow the number of patients eligible for testing. In the United States, we are currently conducting multiple clinical studies focused on expanding the addressable patient populations who qualify for hereditary cancer testing. Upon completion of these studies, we plan to work with professional guideline organizations to expand access to our hereditary cancer testing products.

2. Launch new products across a diverse set of disease indications—We plan to continue to use our proprietary DNA sequencing, RNA expression and protein analysis technologies, including our supporting bioinformatics and robotic technologies, in an effort to efficiently discover important genes and their proteins and to understand their role in human disease. Based on these biomarkers, we plan to develop highly accurate, informative tests that may help physicians better manage their patients’ healthcare. We believe that our technologies provide us with a significant competitive advantage and the potential for numerous product opportunities. Our goal is to commercialize informative molecular diagnostic tests that can save lives and improve the quality of life of patients. In addition to the commercially marketed products mentioned below in our molecular diagnostic testing segment we have a pipeline of additional publicly announced tests. We believe the global market for all of our commercial and pipeline products exceeds $25 billion annually.

3

3. Expand our molecular diagnostic business internationally—We believe that the market for our molecular diagnostic products in Europe, Latin America and Asia represents an attractive commercial opportunity. We have established sales offices in Germany, France, United Kingdom, Spain, Switzerland, Italy, Australia and Canada; laboratory operations in Germany; and international headquarters in Switzerland. We believe that our hereditary cancer products would benefit patients worldwide by assisting physicians in guiding their health care decisions.

Molecular Diagnostic Testing

Our molecular diagnostic tests are designed to analyze genes, their expression levels and corresponding proteins to assess an individual’s risk for developing disease later in life, accurately diagnose disease, determine a patient’s likelihood of responding to a particular drug, or assess a patient’s risk of disease progression and disease recurrence. Provided with this valuable information, physicians may more effectively manage their patient’s healthcare to prevent or delay the onset of disease and help ensure that patients receive the most appropriate treatment for their disease.

Below are the descriptions of our primary molecular diagnostic tests:

• myRisk™ Hereditary Cancer: DNA sequencing test for assessing the risks for hereditary cancers. Our myRisk Hereditary Cancer test represents the next generation of our existing hereditary cancer testing franchise which we anticipate will eventually replace our current predictive medicine test offerings (BRACAnalysis, BART, Colaris and Colaris AP and Melaris) with a single comprehensive test. myRisk Hereditary Cancer is designed to determine a patient’s hereditary cancer risk for breast cancer, ovarian cancer, colon cancer, uterine cancer, melanoma, pancreatic cancer, prostate cancer and gastric cancer. The test analyzes 25 separate genes to look for deleterious mutations that would put a patient at a substantially higher risk than the general population for developing one or more of the above cancers. All 25 genes in the panel are well documented in clinical literature for the role they play in hereditary cancer and have been shown to have actionable clinical interventions for the patient to lower disease risk or risk of cancer recurrence. The myRisk report presents the myRisk Genetic Test Result and myRisk Management Tool that summarizes published management guidelines related to the patient’s genetic mutation as well as their personal and family history of cancer. myRisk Hereditary Cancer testing identifies more mutation carriers than BRACAnalysis^® and COLARIS^® combined. We believe the global market for myRisk Hereditary Cancer and all of our hereditary cancer tests is approximately $5 billion annually. myRisk Hereditary Cancer was initially released through an early access launch that began in September 2013.

• BRACAnalysis^®: DNA sequencing test for assessing the risk of developing breast and ovarian cancer. Our BRACAnalysis test is an analysis of the BRCA1 and BRCA2 genes for assessing a woman’s risk of developing hereditary breast and ovarian cancer. A woman who tests positive for a deleterious mutation with the BRACAnalysis test has up to an 87% risk of developing breast cancer and up to a 44% risk of developing ovarian cancer by age 70. As published in the Journal of the National Cancer Institute, researchers have shown that pre-symptomatic individuals who have a high risk of developing breast or ovarian cancer can reduce their risk by more than 50% with appropriate preventive therapies. Additionally, BRACAnalysis may be used to assist patients already diagnosed with breast or ovarian cancer and their physicians in determining the most appropriate therapeutic interventions to address their disease.

According to the American Cancer Society, in 2015 there will be approximately 253,000 women in the United States diagnosed with breast cancer or ovarian cancer.

• BART^®: DNA sequencing test for hereditary breast and ovarian cancer. Our BART test is based on proprietary technology for detecting large genomic rearrangements in the genes involved in hereditary breast and ovarian cancer patients. As published in the journal Cancer, researchers have shown that up to 10% of hereditary breast and ovarian cancer susceptibility is due to large rearrangement mutations that can’t be detected using conventional sequencing technology.

• BRACAnalysis CDx ^™: DNA sequencing test for use as a companion diagnostic with the PARP inhibitor Lynparza^TM (olaparib) currently indicated for use in identifying ovarian cancer patients with deleterious or suspected deleterious germline BRCA variants eligible for treatment with Lynparza^TM. Approximately 15% of patients with epithelial ovarian cancer are BRCA positive.

4

• Tumor BRACAnalysis CDx ^™: DNA sequencing test designed to be utilized to predict response to DNA damaging agents such as platinum based chemotherapy agents and poly ADP ribose (PARP) inhibitors. Tumor BRACAnalysis CDx looks at both germline and somatic mutations in the BRCA1 and BRCA2 genes giving a more complete picture of potential loss of DNA repair ability within the tumor. Approximately 22% of epithelial ovarian cancer patients will test positive for Tumor BRACAnalysis CDx. Currently the test is only offered through our European laboratory in Munich Germany.

• COLARIS^®: DNA sequencing test for assessing the risk of colorectal and uterine cancer. Our COLARIS test is an analysis of the MLH1, MSH2, MSH6, PMS2, EPCAM and MYH genes for assessing a person’s risk of developing colorectal and uterine cancer. Individuals who carry a deleterious mutation in one of the colon cancer genes in the COLARIS test have a greater than 80% lifetime risk of developing colon cancer and women have up to a 71% lifetime chance of developing uterine cancer. Colon cancer is a preventable disease if high-risk individuals diligently have colonoscopies and remove any precancerous polyps.

According to the American Cancer Society, approximately 200,000 new cases of colorectal cancer or uterine cancer will be diagnosed in the United States in 2015. According to the American Society of Clinical Oncologists, familial forms of colorectal cancer are estimated to account for 10% to 30% of all cases.

• COLARIS AP^®: DNA sequencing test for assessing the risk of colorectal cancer. Our COLARIS AP test detects mutations in the APC and MYH genes, which cause a colon polyp-forming syndrome such as familial adenomatous polyposis (FAP), a more common variation of the syndrome known as attenuated FAP, and the MYH-associated polyposis signature (MAP). Individuals who carry a deleterious mutation in the APC or MYH gene may have a greater than 90% lifetime risk of developing colon cancer. Effective preventive measures include colonoscopy and the removal of pre-cancerous polyps and prophylactic surgery.

• Vectra^®DA: protein detection test for assessing the disease activity of rheumatoid arthritis. Our Vectra DA test is a quantitative, objective multi-biomarker blood test validated to measure rheumatoid arthritis (RA) disease activity. Vectra DA assesses multiple mechanisms and pathways associated with RA disease activity and integrates the concentrations of 12 serum proteins into a single score reported on a scale of 1 to 100. The test may be used throughout the course of a patient’s disease and provides clinicians with expanded insight on disease severity and the risk of radiographic progression.

According to the Arthritis Foundation, there are over 1.5 million Americans with rheumatoid arthritis. We believe the global market for Vectra DA is approximately $3 billion annually. Vectra DA accounted for 6.0% of our total revenue during the year ended June 30, 2015.

• Prolaris^®: RNA expression test for assessing the aggressiveness of prostate cancer. Our Prolaris test is a gene expression assay that assesses whether a patient is likely to have a slow growing, indolent form of prostate cancer that can be safely monitored through active surveillance, or a more aggressive form of the disease that would warrant aggressive intervention such as a radical prostatectomy or radiation therapy. The Prolaris test was developed to improve physicians’ ability to predict disease outcome and to thereby optimize patient treatment.

According to the American Cancer Society, in the United States approximately 220,000 men are expected to be diagnosed with prostate cancer in 2014. We believe the global market for Prolaris is approximately $1.5 billion annually.

• EndoPredict^®: RNA expression test for assessing the aggressiveness of breast cancer. The EndoPredict test, licensed for distribution outside the U.S., is a next-generation RNA expression test used to determine which women with breast cancer would benefit from chemotherapy. EndoPredict predicts the likelihood of metastases to help guide treatment decisions for chemotherapy and extended anti-hormonal therapy. EndoPredict has been shown to accurately predict cancer-specific disease progression and metastases with no confusing intermediate results in 13 published clinical studies with more than 2,200 patients and is CE marked. We believe the international market for EndoPredict is approximately $400 million annually.

5

• myPath^™ Melanoma: RNA expression test for diagnosing melanoma. Our myPath Melanoma test is a gene expression based profile that is performed on biopsy tissue for the purpose of aiding a dermatopathologist in the diagnosis of melanoma. Every year in the United States, there are approximately two million skin biopsies performed specifically for the diagnosis of melanoma. Approximately 14% of these biopsies are classified as indeterminate where a dermatopathologist cannot make a definitive call as to whether the biopsy is benign or malignant. Outcomes for patients are poor if melanoma is not caught in early stages with five year survival rates dropping from 98% for stage 1 cancer to less than 20% for stage 4 cancer based upon data from the American Cancer Society. We believe myPath Melanoma may provide an accurate tool to assist physicians in correctly diagnosing indeterminate skin lesions.

There are approximately 280,000 indeterminate diagnosis of melanoma every year in the United States. We believe the global market for myPath Melanoma is approximately $1 billion annually. myPath Melanoma was released through an early access launch that began in November 2013.

• myPlan^™ Lung Cancer: RNA expression test for assessing the aggressiveness of lung cancer. Our myPlan Lung Cancer test is a gene expression based profile that may aid a physician in making a determination as to the aggressiveness of a patient’s lung cancer and based upon this determination more accurately guide patient therapy. Most early stage lung cancer patients do not see added benefit from chemotherapy. We believe this test may be clinically applicable in the approximately 30,000 new lung cancer diagnoses every year that are early stage lung cancer. We believe the global market for myPlan Lung Cancer is approximately $200 million annually.

myPlan Lung Cancer was released through an early access launch that began in October 2013.

Pharmaceutical and Clinical Services

Our pharmaceutical and clinical services consist of the following:

• Through Myriad RBM, we provide biomarker discovery and pharmaceutical and clinical services to the pharmaceutical, biotechnology, and medical research industries utilizing our multiplexed immunoassay technology. Our technology enables us to efficiently screen large sets of well-characterized clinical samples from both diseased and non-diseased populations against our extensive menu of biomarkers. During the year ended June 30, 2015, Myriad RBM accounted for 2.9% of total revenue. In addition to the fees received from analyzing these samples, we also use this information to create and validate potential companion diagnostic test panels.

• On February 27, 2015, we completed the acquisition of Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG (the “Clinic”) located approximately 15 miles from the Company’s European laboratories in Munich, Germany for total consideration of $20.1 million. We believe the acquisition of the Clinic should facilitate our penetration into the German molecular diagnostic market. The Clinic will allow us to directly negotiate reimbursement with government and private insurance providers for our tests in the German market and collaborate with hospitals and physician groups.

The Molecular Diagnostic Industry and Competition

The markets in which we compete are rapidly evolving, and we face competition from multiple public companies, private companies, and academic/university laboratories for a number of our laboratory testing services.

In the hereditary cancer testing market we have faced increased competition since a landmark U.S. Supreme Court decision in June 2013 invalidated some of the key patent claims covering our hereditary cancer testing products. These patents were originally set to begin expiring in 2015 and beyond. Since this Supreme Court decision, numerous large reference laboratories, small private laboratories, and academic/university laboratories have launched competing hereditary cancer tests. Two years following the Supreme Court decision, we believe we currently have approximately 90 percent market share in the U.S. hereditary cancer testing market.

The market for hereditary cancer testing has evolved dramatically over time. Broad reimbursement coverage for hereditary cancer tests began emerging in the early 2000s and coupled with increased public awareness around genetics and Myriad’s marketing and promotional efforts, there has been significant growth in testing volumes. One of the largest drivers of growth

6

has been increased testing in asymptomatic patients in the preventive care setting which now comprise nearly half of all tests performed in the United States. We are working to continue to expand awareness around hereditary cancer testing and expand the number of patients that qualify for hereditary cancer testing under medical guidelines and health insurance coverage policies.

Another factor influencing the marketplace has been the advent of next generation sequencing. This has allowed the transition from single syndrome tests to targeted pan-cancer panels in a cost effective manner without sacrificing test accuracy. We launched our first pan-cancer panel, myRisk Hereditary Cancer, in September, 2013, and we believe panel based tests will become standard of care in the marketplace based upon their greater sensitivity at finding cancer causing mutations. We have presented multiple studies showing that myRisk Hereditary Cancer can detect greater than 60 percent more deleterious mutations when compared to our legacy hereditary cancer tests. As of June 30, 2015, approximately 72 percent of our hereditary cancer testing business had been transitioned to myRisk Hereditary Cancer from our legacy single syndrome tests.

Myriad competes in the hereditary cancer testing market based upon several factors including:

1) the analytical accuracy of our tests

2) our ability to classify genetic variants in hereditary cancer genes

3) the quality of our sales and marketing for our products

4) the quality of our customer service and support

5) turnaround time; and

6) value

We believe that we have substantial advantages in terms of our test accuracy and ability to classify variants. Based on our testing experience of over 1.5 million patients, and our substantial investments in our variant classification program, we have compiled a proprietary database of over 30,000 unique genetic variants in the genes tested by myRisk Hereditary Cancer. We believe this database allows us to provide more accurate results to patients and return a variant of unknown significance (VUS) result to patients less frequently. We have demonstrated that this classification advantage leads to lower long-term healthcare costs and lower utilization of unnecessary healthcare services.

Given our scale relative to other laboratories in the hereditary cancer testing market, we believe we also have substantial competitive advantages in terms of cost efficiencies and laboratory automation, which leads to faster turnaround times for our tests.

In the urology market, we compete against a small number of public and private companies for our prostate cancer prognostic test, Prolaris. We compete in this market primarily based upon the quality of the clinical data supporting the test, its first mover advantage in the marketplace and the strength of its sales support and customer service.

In the autoimmune market, our Vectra DA test competes primarily against traditional methodologies for assessing rheumatoid arthritis disease activity such as a physician’s clinical assessment of the patient and single marker laboratory tests such as C-reactive protein (CRP). We believe we have the only clinically validated multi-biomarker product on the market to assess rheumatoid arthritis disease activity.

In the pharmaceutical and clinical services segment, our Myriad RBM division competes against other contract research organizations and academic laboratories for business from pharmaceutical and research customers.

Sales and Marketing

We plan to sell our tests through our own direct sales force and marketing efforts in the United States, Europe, Australia and Canada. Our United States sales force is comprised of approximately 590 individuals across five separate sales channels. In connection with any additional tests that we may launch, we plan to expand our existing oncology, preventive care, urology, dermatology, and autoimmune care sales forces, and build new sales forces to address other physician specialty groups. We have entered into distributor agreements with organizations in selected European, Latin American, Middle Eastern, Asian and African countries.

7

Research and Development

We plan to continue to use our proprietary DNA sequencing, RNA expression and protein analysis technologies, including our supporting bioinformatics and robotic technologies, in an effort to efficiently discover important genes and their proteins and to understand their role in human disease. Based on these biomarkers we plan to develop highly accurate, informative tests that may help physicians better manage their patients’ healthcare. We believe that our technologies provide us with a significant competitive advantage and the potential for numerous product opportunities. For the years ended June 30, 2015, 2014 and 2013, we had research and development expense of $75.5 million, $67.5 million and $53.7 million, respectively.

Acquisitions

We intend to continue to take advantage of in-licensing or acquisition opportunities to augment our internal research and development programs. We recognize that we cannot meet all of our research discovery goals internally and can benefit from the research performed by other organizations. We hope to leverage our financial strength, product development expertise, and sales and marketing presence to acquire new product opportunities in our molecular diagnostic areas of focus.

In February 2014, we completed the acquisition of privately-held Crescendo Bioscience, Inc. (“Crescendo”) for $270 million in cash, which was reduced by the repayment of a loan made to Crescendo and other customary adjustments in accordance with the acquisition agreement. We believe that the acquisition of Crescendo facilitates our entry into the high growth autoimmune and inflammatory disease market, diversifies our product revenues and enhances our strength in protein-based diagnostics. The business of Crescendo, including its Vectra^®DA blood test for rheumatoid arthritis disease management, is operated as a wholly owned subsidiary.

In February 2015, we completed the acquisition of the Clinic located in Germany approximately 15 miles from our European laboratories in Munich, Germany for total consideration of $20.1 million. We believe the acquisition of the Clinic should facilitate our penetration into the German molecular diagnostic market. The Clinic will allow us to directly negotiate reimbursement with government and private insurance providers in the German market and collaborate with hospitals and physician groups.

Seasonality

We experience seasonality in our testing business. The volume of testing is negatively impacted by the summer holiday season which is generally reflected in our fiscal first quarter. Our fiscal second quarter ending December 31 is generally strong as we see an increase in volume from patients who have met their annual insurance deductible. Conversely, fiscal third quarter ending March 31 is typically negatively impacted by the annual reset of patient deductibles. Additionally, we can experience increases in testing volume due to celebrity publicity.

Patents and Proprietary Rights

We own or have license rights to issued patents as well as numerous patent applications in the United States and foreign countries. These patents and patent applications cover a variety of subject matter including, diagnostic biomarkers, gene expression signatures, antibodies, primers, probes, assays, disease-associated genetic mutations, methods for determining genetic predisposition, methods for disease diagnosis, methods for determining disease progression, methods for disease treatment, and general molecular diagnostic techniques. For some of the patents, we hold rights through exclusive or non-exclusive license agreements. We also own additional patent applications and hold other non-exclusive license rights to patents which cover various aspects of our tests or processes. The patent protection for our key tests is described below.

myRisk Hereditary Cancer. We own or have exclusive license rights to issued U.S. patents and pending U.S. patent applications relating to myRisk Hereditary Cancer testing. Subject to applicable extensions, we anticipate that the expiration dates of these patents ranging from 2015 up to the last patent, if issued from the currently pending applications, expected to expire in 2035. These patents and patent applications disclose and claim varied subject matter, including claims relating to compositions of matter on synthetic nucleic acids, probes and primers, methods of detecting genetic mutations in the 25 genes that comprise the test (individually and in numerous combinations) and the use thereof for diagnosing predisposition to various cancers, and general molecular diagnostic technology relating to myRisk Hereditary Cancer.

8

BRACAnalysis. We own issued U.S. patents relating to BRACAnalysis^® testing, including BRACAnalysis CDx testing. These U.S. patents have terms that are expected to expire commencing in 2015, with the last patent expected to expire in 2025. These patents contain multiple claims, including claims relating to compositions of matter on synthetic BRCA1 and BRCA2 nucleic acids, probes and primers, methods of detecting genetic mutations in the BRCA1 and BRCA2 genes and the use thereof for diagnosing predisposition to breast or ovarian cancer, and general molecular diagnostic technology relating to BRACAnalysis testing.

BART. We own issued U.S. patents relating to BART testing. These U.S. patents have terms that are expected to expire commencing in 2015, with the last patent expected to expire in 2025. These patents contain multiple claims, including but not limited to claims relating to composition of matter on synthetic BRAC1 and BRCA2 nucleic acids, composition of matter on probes and primers, methods of detecting genomic rearrangements and methods of determining BRCA1 and BRCA2 related predisposition to cancer.

COLARIS and COLARIS AP. We own issued U.S. patents relating to COLARIS and COLARIS AP testing. These U.S. patents have terms that began to expire commencing in 2017, with the last patent expected to expire in 2026. These patents contain multiple claims, including but not limited to claims relating to compositions of matter on synthetic MUTYH nucleic acids, methods of detecting mutations in the MUTYH gene, methods for determining MUTYH- related predisposition to cancer, and general molecular diagnostic technology applicable to COLARIS and COLARIS AP testing.

Vectra DA. We hold an exclusive license to pending U.S. patent applications relating to Vectra^®DA testing. These U.S. applications, if issued as patents, will have terms that begin to expire commencing in 2030. These patents contain multiple claims including but not limited to claims relating to biomarkers, kits, systems and methods for measuring and monitoring inflammatory disease activity.

We intend to seek patent protection in the United States and major foreign jurisdictions for synthetic nucleic acids, antibodies, biomarker signatures, assays, probes, primers, technologies, methods, processes and other inventions which we believe are patentable and where we believe our interests would be best served by seeking patent protection. However, any patents issued to us or our licensors may not afford meaningful protection for our products or technology or may be subsequently circumvented, invalidated or narrowed or found unenforceable, such as occurred in our two recent court cases: Association for Molecular Pathology et al. v. Myriad Genetics, Inc. et al. and University of Utah Research Foundation et al. v. Ambry Genetics Corp. et al. Any patent applications which we have filed or will file or to which we have licensed or will license rights may not issue, and patents that do issue may not contain commercially valuable claims. In addition, others may obtain patents having claims which cover aspects of our tests or processes which are necessary for or useful to the development, use or performance of our diagnostic products. Should any other group obtain patent protection with respect to our discoveries, our commercialization of our molecular diagnostic tests could be limited or prohibited.

Others may offer clinical diagnostic genomic laboratory testing services which may infringe patents we control. We may seek to negotiate a license to use our patent rights or decide to seek enforcement of our patent rights through litigation. Patent litigation is expensive and the outcome is often uncertain and we may not be able to enforce our patent rights against others.

Our tests and processes may also conflict with patents which have been or may be granted to competitors, academic institutions or others. In addition, third parties could bring legal actions against us seeking to invalidate our owned or licensed patents, claiming damages, or seeking to enjoin clinical testing, developing and marketing of our tests or processes. If any of these actions are successful, in addition to any potential liability for damages, we could lose patent coverage for our tests, be required to cease the infringing activity or obtain a license in order to continue to develop or market the relevant test or process. We may not prevail in any such action, and any license required under any such patent may not be made available on acceptable terms, if at all. Our failure to maintain patent protection for our test and processes or to obtain a license to any technology that we may require to commercialize our tests and technologies could have a material adverse effect on our business.

We also rely upon unpatented proprietary technology, and in the future may determine in some cases that our interests would be better served by reliance on trade secrets or confidentiality agreements rather than patents or licenses. These include some of our genomic, proteomic, RNA expression, mutation analysis, robotic and bioinformatic technologies which may be used in discovering and characterizing new genes and proteins and ultimately used in the development or analysis of molecular diagnostic tests. We also maintain a database of gene mutations and their status as either harmful or benign for all of our hereditary cancer tests. To further protect our trade secrets and other proprietary information, we require that our employees and consultants enter into confidentiality and invention assignment agreements. However, those confidentiality and invention

9

assignment agreements may not provide us with adequate protection. We may not be able to protect our rights to such unpatented proprietary technology and others may independently develop substantially equivalent technologies. If we are unable to obtain strong proprietary rights to our processes or tests, competitors may be able to market competing processes and tests.

License Agreements

We are a party to license agreements which give us the rights to use certain technologies in the research, development, testing processes, and commercialization of our molecular diagnostic tests and pharmaceutical and clinical services. We may not be able to continue to license these technologies on commercially reasonable terms, if at all. Additionally, patents underlying our license agreements may not afford meaningful protection for our technology or tests or may be subsequently circumvented, invalidated or narrowed, or found unenforceable. Our failure to maintain rights to this technology could have a material adverse effect on our business.

In 2010, Crescendo Bioscience, Inc. (now a wholly-owned subsidiary of the Company) entered into a license agreement with the Oklahoma Medical Research Foundation (the “OMRF”), for the exclusive world-wide right to utilize certain intellectual property rights of OMRF including patent applications relating to what is now Vectra^®DA testing. Under this license agreement we pay OMRF a royalty based on net sales of our Vectra^®DA test. This license agreement ends on expiration of the last to expire patent covered by the license agreement, which presently is not anticipated to expire until 2030. OMRF has the right to terminate the license agreement for the uncured breach of any material term of the license agreement.

In 2014, Myriad Genetics GmbH entered into a Distribution and Development Agreement with Sividon Diagnostics GmbH (“Sividon”) for the exclusive right to market, sell and distribute the EndoPredict test in various worldwide countries, excluding the United States. Under the agreement, we purchase the EndoPredict test from Sividon for marketing and resale in the authorized countries. The agreement has an initial term which expires in January of 2017. Sividon may terminate the agreement, on a country by country basis with immediate effect if certain revenue commitments are not accomplished for the specified country. We have the right to terminate the agreement without cause upon six months’ notice. Additionally, either party may terminate the agreement for material, uncured breaches, or immediately on a country by country basis for infringement of intellectual property rights. Following termination of the agreement, we have a period of nine months to sell existing inventories of the EndoPredict test. The agreement is renewable for an additional two year term upon the mutual agreement of the parties.

Governmental Regulation

The services that we provide are regulated by federal, state and foreign governmental authorities. Failure to comply with the applicable laws and regulations can subject us to repayment of amounts previously paid to us, significant civil and criminal penalties, loss of licensure, certification, or accreditation, or exclusion from state and federal health care programs. The significant areas of regulation are summarized below.

Clinical Laboratory Improvement Amendments of 1988 and State Regulation

Each of our clinical laboratories must hold certain federal, state and local licenses, certifications and permits to conduct our business. Laboratories in the United States that perform testing on human specimens for the purpose of providing information for the diagnosis, prevention, or treatment of disease are subject to the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”). CLIA requires such laboratories to be certified by the federal government and mandates compliance with various operational, personnel, facilities administration, quality and proficiency testing requirements intended to ensure that testing services are accurate, reliable and timely. CLIA certification also is a prerequisite to be eligible to bill state and federal health care programs, as well as many private insurers, for laboratory testing services. Our laboratories in Salt Lake City, Utah, Austin, Texas and South San Francisco, California are CLIA certified to perform high complexity tests.

In addition, CLIA requires each of our certified laboratories to enroll in an approved proficiency testing program if performing testing in any category for which proficiency testing is required. Each of our laboratories periodically tests specimens received from an outside proficiency testing organization and then submits the results back to that organization for evaluation. If one of our laboratories fails to achieve a passing score on a proficiency test, then it loses its right to perform testing. Further, failure to comply with other proficiency testing regulations, such as the prohibition on referral of a proficiency testing specimen to another laboratory for analysis, can result in revocation of the laboratory’s CLIA certification.

10

As a condition of CLIA certification, each of our laboratories is subject to survey and inspection every other year, in addition to being subject to additional random inspections. The biennial survey is conducted by the Centers for Medicare & Medicaid Services (“CMS”), a CMS agent (typically a state agency), or, a CMS-approved accreditation organization. Because our laboratories are accredited by the College of American Pathologists (“CAP”), which is a CMS-approved accreditation organization, they are typically subject to CAP inspections.

Our laboratories are licensed by the appropriate state agencies in the states in which they operate, if such licensure is required. In addition, our laboratories hold state licenses from California, Florida, New York, Pennsylvania, Rhode Island and Maryland, to the extent that they accept specimens from one or more of these states, each of which requires out-of-state laboratories to obtain licensure.

If a laboratory is out of compliance with state laws or regulations governing licensed laboratories or with CLIA, may include suspension, limitation or revocation of the license or CLIA certificate, assessment of financial penalties or fines, or imprisonment. Loss of a laboratory’s CLIA certificate or state license may also result in the inability to receive payments from state and federal health care programs as well as private third party payors. We believe that we are in material compliance with CLIA and all applicable licensing laws and regulations.

Food and Drug Administration

Although the Food and Drug Administration (FDA) has consistently claimed that it has the authority to regulate laboratory-developed tests (“LDTs”) that are developed, validated and performed only by a CLIA certified laboratory, it has historically exercised enforcement discretion in not otherwise regulating most LDTs and has not required laboratories that furnish LDTs to comply with the agency’s requirements for medical devices (e.g., establishment registration, device listing, quality systems regulations, premarket clearance or premarket approval, and post-market controls). In recent years, however, the FDA has stated it intends to end its policy of general enforcement discretion and regulate certain LDTs as medical devices. To this end, on October 3, 2014, the FDA issued two draft guidance documents, entitled “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests (LDTs)”, respectively, that set forth a proposed risk-based regulatory framework that would apply varying levels of FDA oversight to LDTs. The FDA has indicated that it does not intend to modify its policy of enforcement discretion until the draft guidance documents are finalized. It is unclear at this time when, or if, the draft guidance documents will be finalized, and even then, the new regulatory requirements are proposed to be phased-in consistent with the schedule set forth in the guidance (in as little as 12 months after the draft guidance is finalized for certain high-priority LDTs). Nevertheless, the FDA may decide to regulate certain LDTs on a case-by-case basis at any time. LDTs with the same intended use as a cleared or approved companion diagnostic are defined in FDA’s draft guidance as “high-risk LDTs (Class III medical devices)” for which premarket review would be first to occur.

We are developing companion diagnostic tests for use with drug products in development by pharmaceutical companies, such as our collaborations with pharmaceutical companies on PARP inhibitors for the treatment of ovarian, breast and other cancers. Companion diagnostic tests are currently subject to regulation by the FDA as medical devices. The FDA issued Guidance on In-Vitro Companion Diagnostic Devices in July 2014, which is intended to assist companies developing in vitro companion diagnostic devices and companies developing therapeutic products that depend on the use of a specific in vitro companion diagnostic for the safe and effective use of the product. The FDA defined an in vitro companion diagnostic device (“IVD Companion Dx”) as a device that provides information that is essential for the safe and effective use of a corresponding therapeutic product. The FDA expects that the therapeutic sponsor will address the need for an approved or cleared IVD Companion Dx in its therapeutic product development plan and that, in most cases, the therapeutic product and its corresponding companion diagnostic will be developed contemporaneously. In December 2014, we obtained premarket approval (“PMA”) for BRACAnalysis CDx, which is used as a companion diagnostic to identify ovarian cancer patients who may benefit from AstraZeneca’s PARP inhibitor Lynparza^™ (olaparib). The premarket approval process is a complex, costly and time consuming procedure. PMAs must be supported by valid scientific evidence, which typically requires extensive data, including quality technical, preclinical, clinical and manufacturing data to demonstrate to the FDA’s satisfaction the safety and effectiveness of the companion diagnostic. We are currently collaborating with several pharmaceutical companies, including an expanded collaboration with AstraZeneca for an additional indication for BRACAnalysis CDx, to evaluate the use of several of our tests as companion diagnostics with other drugs.

11

After a medical device is placed on the market, numerous regulatory requirements apply. These include:

• compliance with the FDA’s Quality System Regulation (“QSR”), which requires manufacturers to follow stringent design, testing, control, documentation, record maintenance, including maintenance of complaint and related investigation files, and other quality assurance controls during the manufacturing process;

• labeling regulations, which prohibit the promotion of products for uncleared, unapproved or “off-label” uses and impose other restrictions on labeling; and

• medical device reporting obligations, which require that manufacturers investigate and report to the FDA adverse events, including deaths, or serious injuries that may have been or were caused by a medical device and malfunctions in the device that would likely cause or contribute to a death or serious injury if it were to recur.

Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include sanctions, including but not limited to, warning letters; fines, injunctions, and civil penalties; recall or seizure of the device; operating restrictions, partial suspension or total shutdown of production; refusal to grant 510(k) clearance or PMAs of new devices; withdrawal of 510(k) clearance or PMAs; and civil or criminal prosecution. To ensure compliance with regulatory requirements, medical device manufacturers are subject to market surveillance and periodic, pre-scheduled and unannounced inspections by the FDA.

Other Regulatory Requirements

Our laboratories are subject to federal, state and local regulations relating to the handling and disposal of regulated medical waste, hazardous waste and biohazardous waste, including chemical, biological agents and compounds, blood and bone marrow samples and other human tissue. Typically, we use outside vendors who are contractually obligated to comply with applicable laws and regulations to dispose of such waste. These vendors are licensed or otherwise qualified to handle and dispose of such waste.

HIPAA and other privacy laws

The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), established comprehensive federal standards for the privacy and security of health information. The HIPAA standards apply to three types of organizations: health plans, healthcare clearing houses, and healthcare providers that conduct certain healthcare transactions electronically (“Covered Entities”). Title II of HIPAA, the Administrative Simplification Act, contains provisions that address the privacy of health data, the security of health data, the standardization of identifying numbers used in the healthcare system and the standardization of certain healthcare transactions. The privacy regulations protect medical records and other protected health information by limiting their use and release, giving patients the right to access their medical records and limiting most disclosures of health information to the minimum amount necessary to accomplish an intended purpose. The HIPAA security standards require the adoption of administrative, physical, and technical safeguards and the adoption of written security policies and procedures.

On February 17, 2009, Congress enacted Subtitle D of the Health Information Technology for Economic and Clinical Health Act, or HITECH, provisions of the American Recovery and Reinvestment Act of 2009. HITECH expanded and strengthened HIPAA, created new targets for enforcement, imposed new penalties for noncompliance and established new breach notification requirements for Covered Entities. Regulations implementing major provisions of HITECH were finalized on January 25, 2013 through publication of the HIPAA Omnibus Rule (the “Omnibus Rule”).

Under HITECH’s breach notification requirements, Covered Entities must report breaches of protected health information that has not been encrypted or otherwise secured in accordance with guidance from the Secretary of the U.S. Department of Health and Human Services (the “Secretary”). Required breach notices must be made as soon as is reasonably practicable, but no later than 60 days following discovery of the breach. Reports must be made to affected individuals and to the Secretary and, in some cases depending on the size of the breach; they must be reported through local and national media. Breach reports can lead to investigation, enforcement and civil litigation, including class action lawsuits.

We are currently subject to the HIPAA regulations and maintain an active compliance program that is designed to identify security incidents and other issues in a timely fashion and enable us to remediate, mitigate harm or report if required by law. We are subject to prosecution and/or administrative enforcement and increased civil and criminal penalties for non-compliance,

12

including a new, four-tiered system of monetary penalties adopted under HITECH. We are also subject to enforcement by state attorneys general who were given authority to enforce HIPAA under HITECH. To avoid penalties under the HITECH breach notification provisions, we must ensure that breaches of protected health information are promptly detected and reported within the company, so that we can make all required notifications on a timely basis. However, even if we make required reports on a timely basis, we may still be subject to penalties for the underlying breach.

In addition to the federal privacy and security regulations, there are a number of state laws regarding the privacy and security of health information and personal data that are applicable to our clinical laboratories. Many states have also implemented genetic testing and privacy laws imposing specific patient consent requirements and protecting test results by strictly limiting the disclosure of those results. State requirements are particularly stringent regarding predictive genetic tests, due to the risk of genetic discrimination against healthy patients identified through testing as being at a high risk for disease. We believe that we have taken the steps required of us to comply with health information privacy and security statutes and regulations, including genetic testing and genetic information privacy laws in all jurisdictions, both state and federal. However, these laws constantly change and we may not be able to maintain compliance in all jurisdictions where we do business. Failure to maintain compliance, or changes in state or federal laws regarding privacy or security could result in civil and/or criminal penalties, significant reputational damage and could have a material adverse effect on our business.

We are subject to laws and regulations related to the protection of the environment, the health and safety of employees and the handling, transportation and disposal of medical specimens, infectious and hazardous waste and radioactive materials. For example, the U.S. Occupational Safety and Health Administration (“OSHA”) has established extensive requirements relating specifically to workplace safety for healthcare employers in the U.S. This includes requirements to develop and implement multi-faceted programs to protect workers from exposure to blood-borne pathogens, including preventing or minimizing any exposure through needle stick injuries. For purposes of transportation, some biological materials and laboratory supplies are classified as hazardous materials and are subject to regulation by one or more of the following agencies: the U.S. Department of Transportation, the U.S. Public Health Service, the United States Postal Service and the International Air Transport Association. We generally use third-party vendors to dispose of regulated medical waste, hazardous waste and radioactive materials and contractually require them to comply with applicable laws and regulations.

Transparency Laws and Regulations

A federal law known as the Physician Payments Sunshine Act (the “Sunshine Act”) requires medical device manufacturers to track and report to the federal government certain payments and other transfers of value made to physicians and teaching hospitals and ownership or investment interests held by physicians and their immediate family members. Manufacturers must report data for the previous calendar year by the 90^th day of the then-current calendar year. CMS then publishes the data on a publicly available website no later than June 30^th. There are also state “sunshine” laws that require manufacturers to provide reports to state governments on pricing and marketing information. Several states have enacted legislation requiring medical device manufacturers to, among other things, establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales and marketing activities, and such laws may also prohibit or limit certain other sales and marketing practices. These laws may adversely affect our sales, marketing, and other activities by imposing administrative and compliance burdens on us. If we fail to track and report as required by these laws or to otherwise comply with these laws, we could be subject to the penalty provisions of the pertinent state and federal authorities.

Reimbursement and Billing

Reimbursement and billing for diagnostic services is highly complex. Laboratories must bill various payors, such as private third-party payors, including managed care organizations (“MCO”), and state and federal health care programs, such as Medicare and Medicaid, and each may have different billing requirements. Additionally, the audit requirements we must meet to ensure compliance with applicable laws and regulations, as well as our internal compliance policies and procedures, add further complexity to the billing process. Other factors that complicate billing include:

• variability in coverage and information requirements among various payors;

• missing, incomplete or inaccurate billing information provided by ordering physicians;

• billings to payors with whom we do not have contracts;

• disputes with payors as to which party is responsible for payment; and

13

• disputes with payors as to the appropriate level of reimbursement.

Depending on the reimbursement arrangement and applicable law, the party that reimburses us for our services may be:

• a third party who provides coverage to the patient, such as an insurance company or MCO;

• a state or federal healthcare program; or

• the patient.

Presently, approximately 85% of our revenue comes from private third party payors.

In February 2011, the American Medical Association Current Procedural Terminology (“CPT”) Editorial Panel approved 101 new molecular pathology codes to describe molecular diagnostic tests that currently require multiple CPT codes for billing purposes. The new reimbursement rates for the new codes went into effect on January 1, 2013.

Federal and State Fraud and Abuse Laws

A variety of federal laws prohibit fraud and abuse involving state and federal health care programs, such as Medicare and Medicaid. These laws are interpreted broadly and enforced aggressively by various state and federal agencies, including CMS, the Department of Justice, the Office of Inspector General for the Department of Health and Human Services (“OIG”), and various state agencies. In addition, the Medicare and Medicaid programs increasingly use a variety of contractors to review claims data and to identify improper payments as well as fraud and abuse. Any overpayments must be repaid within 60 days of identification unless a favorable decision is obtained on appeal. In some cases, these overpayments can be used as the basis for an extrapolation, by which the error rate is applied to a larger universe of claims, and which can result in even higher repayments.

Anti-Kickback Laws

The Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for or recommending of an item or service that is reimbursable, in whole or in part, by a federal health care program. “Remuneration” is broadly defined to include anything of monetary value, such as, for example, cash payments, gifts or gift certificates, discounts, or the furnishing of services, supplies or equipment. The Anti-Kickback Statue is broad and prohibits many arrangements and practices that are lawful in businesses outside of the health care industry.

Recognizing the breadth of the Anti-Kickback Statute and the fact that it may technically prohibit many innocuous or beneficial arrangements within the health care industry, the OIG has issued a series of regulations, or safe harbors intended to protect such arrangements. Compliance with all requirements of a safe harbor immunizes the parties to the business arrangement from prosecution under the Anti-Kickback Statute. The failure of a business arrangement to fit within a safe harbor does not necessarily mean that the arrangement is illegal or that the OIG will pursue prosecution. Still, in the absence of an applicable safe harbor, a violation of the Anti-Kickback Statute may occur even if only one purpose of an arrangement is to induce referrals. The penalties for violating the Anti-Kickback Statute can be severe. These sanctions include criminal and civil penalties, imprisonment and possible exclusion from the federal health care programs. Many states have adopted laws similar to the Anti-Kickback Statute, and some apply to items and services reimbursable by any payor, including private third-party payors.

Physician Self-Referral Bans

The federal ban on physician self-referrals, commonly known as the Stark Law, prohibits, subject to certain exceptions, physician referrals of Medicare patients to an entity providing certain designated health services, which include laboratory services, if the physician or an immediate family member of the physician has any financial relationship with the entity. Several Stark Law exceptions are relevant to arrangements involving clinical laboratories, including but not limited to: (1) fair market value compensation for the provision of items or services; (2) payments by physicians to a laboratory for clinical laboratory services; (3) certain space and equipment rental arrangements that satisfy certain requirements; and (4) personal services arrangements. Penalties for violating the Stark Law include the return of funds received for all prohibited referrals, fines, civil monetary penalties and possible exclusion from federal health care programs. In addition to the Stark Law, many states have their own self-referral bans, which may extend to all self-referrals, regardless of the payor.

14

State and Federal Prohibitions on False Claims

The federal False Claims Act imposes liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment to the federal government. Under the False Claims Act, a person acts knowingly if he has actual knowledge of the information or acts in deliberate ignorance or in reckless disregard of the truth or falsity of the information. Specific intent to defraud is not required. The qui tam provisions of the False Claims Act allow a private individual to bring an action on behalf of the federal government and to share in any amounts paid by the defendant to the government in connection with the action. Penalties include payment of up to three times the actual damages sustained by the government, plus civil penalties of between $5,500 and $11,000 for each false claim, as well as possible exclusion from the federal health care programs. In addition, various states have enacted similar laws modeled after the False Claims Act that apply to items and services reimbursed under Medicaid and other state health care programs, and, in several states, such laws apply to claims submitted to any payor.

Civil Monetary Penalties Law

The federal Civil Monetary Penalties Law, or the CMP Law, prohibits, among other things, (1) the offering or transfer of remuneration to a Medicare or state health care program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a particular provider, practitioner, or supplier of services reimbursable by Medicare or a state health care program, unless an exception applies; (2) employing or contracting with an individual or entity that the provider knows or should know is excluded from participation in a federal health care program; (3) billing for services requested by an unlicensed physician or an excluded provider; and (4) billing for medically unnecessary services. The penalties for violating the CMP Law include exclusion, substantial fines, and payment of up to three times the amount billed, depending on the nature of the offense.

International regulations

We market some of our tests outside of the United States and are subject to foreign regulatory requirements governing laboratory licensure, human clinical testing, use of tissue, privacy and data security, and marketing approval for our tests. These requirements vary by jurisdiction, differ from those in the United States and may require us to implement additional compliance measures or perform additional pre-clinical or clinical testing. On September 26, 2012, the European Commission released the first drafts of the new European Union (“EU”) regulations for medical devices and IVDs that if finalized will impose additional regulatory requirements on IVDs used in the EU. In many countries outside of the United States, coverage, pricing and reimbursement approvals are also required. We are also required to maintain accurate information on and control over sales and distributors’ activities that may fall within the purview of the Foreign Corrupt Practices Act, its books and records provisions and its anti-bribery provisions.

Human Resources

As of June 30, 2015, we had 2,038 full-time equivalent employees. Most of our employees are engaged directly in research, development, production, sales and marketing activities. We believe that the success of our business will depend, in part, on our ability to attract and retain qualified personnel. Our employees are not covered by a collective bargaining agreement, and we consider our relations with our employees to be good.

Item 1A. RISK FACTORS

Risks Related to Our Business and Our Strategy

We may not be successful in transitioning from our existing product portfolio to our new products, such as our myRisk Hereditary Cancer test, which represents the next generation of our existing hereditary cancer franchise. We may not be able to generate sufficient revenue from our existing tests and our new tests or develop new tests to maintain profitability.

Although we have developed and marketed several molecular diagnostic tests to date, we believe our future success is dependent upon our ability to successfully market our existing molecular diagnostic tests to additional patients within the United States, to expand into new markets outside the United States, and to develop and commercialize new molecular diagnostic and companion diagnostic tests. Importantly, in 2014 we launched our myRisk Hereditary Cancer test, which represents the next generation of our existing hereditary cancer testing franchise. We anticipate that the myRisk Hereditary Cancer test will eventually replace our current predictive medicine test offerings (BRACAnalysis, BART, Colaris and Colaris AP and Melaris) with a single comprehensive test. However, we may not be successful in transitioning from our existing product portfolio to our new tests and in launching and commercializing our new tests. The demand for our existing molecular diagnostic tests may decrease or may not continue to increase at historical rates due to sales of the myRisk Hereditary Cancer test and our other new tests that are replacing our existing product portfolio, or for other reasons. For example, because most of our molecular diagnostic tests are only utilized once per patient, we will need to sell our services through physicians to new patients or develop new molecular diagnostic tests in order to continue to generate revenue. Our pipeline of new molecular diagnostic and companion diagnostic test candidates is in various stages of development and may take several more years to develop and must undergo extensive clinical validation. We may be unable to discover or develop any additional molecular diagnostic or companion diagnostic tests through the utilization of our technologies or technologies we license or acquire from others. Even if we develop tests or services for commercial use, we may not be able to develop tests or services that:

• meet applicable regulatory standards, in a timely manner or at all;

• successfully compete with other technologies and tests;

• avoid infringing the proprietary rights of others;

• are adequately reimbursed by third-party payors;

• can be performed at commercial levels or at reasonable cost; or

• can be successfully marketed.

We must generate significant revenue to maintain profitability. Even if we succeed in marketing myRisk Hereditary Cancer and our existing molecular diagnostic tests to physicians for use in new patients and in developing and commercializing any additional molecular diagnostic tests and companion diagnostic tests, we may not be able to generate sufficient revenue and we may not be able to maintain profitability.

We may not be able to sustain or increase profitability on a quarterly or annual basis.

In order to develop and commercialize our molecular diagnostic and companion diagnostic tests, we expect to incur significant expenses over the next several years as we increase our research and development activities, expand clinical validation trials for our molecular diagnostic tests and companion diagnostic tests currently in development, potentially license or acquire additional companies or technologies and engage in commercialization activities in anticipation of the launch of additional molecular diagnostic tests companion diagnostic tests. Because of the numerous risks and uncertainties associated with developing our tests and their potential for commercialization, we are unable to predict the extent of any future profits. If we are unable to sustain or increase profitability, the market value of our common stock will likely decline. Our ability to maintain profitability will depend upon numerous factors, including:

• our ability to transition from our existing product portfolio to our new products, such as our MyRisk Hereditary Cancer test, and to commercialize these new tests;

• our ability to obtain full or partial reimbursement for new products;

• our ability to sell our other existing molecular diagnostic tests to new patients;

• our ability to identify biomarkers that may lead to future molecular diagnostic tests and companion diagnostic tests;

• our ability to develop test candidates and receive any required regulatory approvals;

• our ability to successfully commercialize our tests in our existing markets and to extend into new markets outside the United States;

16

• the approval and introduction of competitive tests;

• reductions in reimbursement by third-party payors or their willingness to provide full or even partial reimbursement for our tests;

• our ability to maintain and enforce our intellectual property rights covering our molecular diagnostic tests and companion diagnostic tests;

• our ability to maintain and grow our sales force and marketing team to market our tests;

• our ability to successfully integrate, develop and grow products and services and the business of any other companies or technologies that we may license or acquire;

• our ability to increase commercial acceptance of our current molecular diagnostic tests; and

• our ability to maintain or grow our current revenues.

If we do not continue to generate sufficient revenue from sales of our molecular diagnostic tests and are unable to secure additional funding, we may have to reduce our operations.

As of June 30, 2015, we had $185.4 million in cash, cash equivalents and marketable securities. For the fiscal year ended June 30, 2015 our consolidated revenues were $723.1 million, and net cash from operating activities was $140.5 million. To develop and bring new molecular diagnostic tests and companion diagnostic tests to market, we must commit substantial resources to costly and time-consuming research, development testing and clinical testing.

While we anticipate that our existing cash, cash equivalents and marketable securities and expected net cash to be generated from sales of our molecular diagnostic tests and pharmaceutical and clinical services will be sufficient to fund our current operations for the foreseeable future, changes could occur that would consume available capital resources more quickly than we currently expect and we may need or want to raise additional financing. If we are unable to secure additional funding, we may be required to reduce research and development projects, limit sales and marketing activities, scale back our expansion efforts outside the United States, reduce headcount or potentially even discontinue operations. Our future capital requirements will depend on many factors that are currently unknown to us, including:

• the scope, progress, results and cost of development, clinical testing and pre-market studies of any new molecular diagnostic tests that we may discover or acquire;

• the progress, results, and costs to develop additional molecular diagnostic tests;

• the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our current issued patents, and defending intellectual property-related claims;

• our ability to enter into collaborations, licensing or other arrangements favorable to us;

• the costs of acquiring technologies or businesses, and our ability to successfully integrate and achieve the expected benefits of our business development activities and acquisitions;

• the progress, cost and results of our international expansion efforts;

• the costs of expanding our sales and marketing functions and commercial operation facilities in the United States and in new markets;

• the costs, timing and outcome of any litigation against us; and

• the costs to satisfy our current and future obligations.

We may acquire technologies, assets or other businesses that could cause us to incur significant expense and expose us to a number of unanticipated operational and financial risks.

In addition to organic growth, we intend to continue to pursue growth through the acquisition of technology, assets or other businesses that may enable us to enhance our technologies and capabilities, expand our geographic market, add experienced management personnel and increase our test offerings. For example, in May 2011, we completed the acquisition of Rules Based Medicine, Inc., which we renamed Myriad RBM, and are now offering pharmaceutical and clinical services and developing additional product candidates using the acquired technology. In February 2014, we completed the acquisition of Crescendo Bioscience, Inc., and are now offering molecular diagnostic tests for patients suffering from rheumatoid arthritis and developing additional product candidates in the inflammatory and autoimmune disease area. Additionally, in February 2015, we acquired the Clinic and believe the acquisition may facilitate our penetration into the German molecular diagnostic market. However, these acquisitions may not achieve profitability or generate a positive return on our investment. Additionally, we may be unable

17

to implement our growth strategy if we cannot identify suitable acquisition candidates, reach agreement on potential acquisitions on acceptable terms, successfully integrate personnel or assets that we acquire or for other reasons. Our acquisition efforts may involve certain risks, including:

• we may have difficulty integrating operations and systems;

• key personnel and customers of the acquired company may terminate their relationships with the acquired company as a result of the acquisition;

• we may not be successful in launching new molecular diagnostic tests or companion diagnostic tests, or if those tests are launched they may not prove successful in the market place;

• we may experience additional financial and accounting challenges and complexities in areas such as tax planning and financial reporting;

• we may assume or be held liable for risks and liabilities, including for environmental-related costs, as a result of our acquisitions, some of which we may not discover during our due diligence;

• we may incur significant additional operating expenses;

• our ongoing business may be disrupted or receive insufficient management attention; and

• we may not be able to realize synergies, the cost savings or other financial and operational benefits we anticipated, or such synergies, savings or benefits may take longer than we expected.

The process of negotiating acquisitions and integrating acquired tests, services, technologies, personnel or businesses might result in operating difficulties and expenditures and might require significant management attention that would otherwise be available for ongoing development of our business, whether or not any such transaction is ever consummated. Moreover, we might never realize the anticipated benefits of any acquisition. Future acquisitions could result in the use of our available cash and marketable securities, potentially dilutive issuances of equity securities, the incurrence of debt, contingent liabilities, or impairment expenses related to goodwill, and impairment or amortization expenses related to other intangible assets, which could harm our financial condition. In addition, if we are unable to integrate any acquired businesses, tests or technologies effectively, our business, financial condition and results of operations may be materially adversely affected.

We may not be able to successfully integrate the operations of businesses that we acquire with our own or realize the anticipated benefits of the acquisitions, which could adversely affect our financial condition, results of operations and business prospects.

There can be no assurance that we will be able to successfully integrate our recent acquisitions or develop or commercialize products based on recently acquired technologies, or that we will be able to successfully integrate any other companies, products or technologies that we acquire and may not realize all or any of the expected benefits of any acquisitions as and when planned. Additionally, we may experience increased expenses, distraction of our management, personnel and customer uncertainty.

The difficulties and risks associated with the integration of any other businesses that we may acquire include:

• possible inconsistencies in the standards, controls, procedures, policies and compensation structures;

• the increased scope and complexity of the acquired company’s operations;

• the potential loss of key employees and the costs associated to retain key employees;

• risks and limitations on our ability to consolidate corporate and administrative infrastructures of the two companies; and

• the possibility of unanticipated delays, costs or inefficiencies associated with the integration of our operations with the operations of any other companies that we may acquire.

As a result of these difficulties and risks, we may not accomplish the integration of the business of any companies we may acquire smoothly, successfully or within our budgetary expectations and anticipated timetable. Accordingly, we may fail to realize some or all of the anticipated benefits of the acquisition, such as increase in our scale, diversification, cash flows and operational efficiency and meaningful accretion to our diluted earnings per share.

If we were successfully sued for product liability, we could face substantial liabilities that exceed our resources.

Our business exposes us to potential liability risks inherent in the testing, marketing and processing of molecular diagnostic products, including possible misdiagnoses. Although we are insured against such risks in amounts that we believe to be commercially reasonable, our present professional and product liability insurance may be inadequate. A successful product liability claim in excess of our insurance coverage could have a material adverse effect on our business. Any successful product liability claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable or reasonable terms. An inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against potential product liability claims could prevent or inhibit the commercialization of our products.

We are dependent on our information technology and telecommunications systems, and any failure of these systems could harm our business.

We depend on information technology, or IT, and telecommunications systems for significant aspects of our business. These IT and telecommunications systems support a variety of functions, including sample processing, tracking, quality control, customer service and support, billing, research and development activities, and various general and administrative activities. Failures or significant downtime of our IT or telecommunications systems could prevent us from processing samples, providing test results to physicians, billing payors, addressing patient or physician inquiries, conducting research and development activities and conducting general and administrative elements of our business. Any disruption or loss of IT or telecommunications systems on which critical aspects of our operations depend could have an adverse effect on our business, financial condition and results of operations.

Security breaches, loss of data and other disruptions could compromise sensitive information related to our business, prevent us from accessing critical information or expose us to liability, which could adversely affect our business and our reputation.

In the ordinary course of our business, we collect and store sensitive data, including legally protected patient health information, credit card information, personally identifiable information about our employees, intellectual property, and proprietary business information. We manage and maintain our applications and data utilizing on-site systems. These applications and data encompass a wide variety of business critical information including research and development information, commercial information and business and financial information.

The secure processing, storage, maintenance and transmission of this critical information is vital to our operations and business strategy, and we devote significant resources to protecting such information. Although we take measures to protect sensitive information from unauthorized access or disclosure, our information technology and infrastructure may be vulnerable to attacks by hackers, or viruses, breaches or interruptions due to employee error, malfeasance or other disruptions, or lapses in compliance with privacy and security mandates. Any such virus, breach or interruption could compromise our networks and the information stored there could be accessed by unauthorized parties, publicly disclosed, lost or stolen. We have measures in place that are designed prevent, and if necessary to detect and respond to such security incidents and breaches of privacy and security mandates. While we have experienced unauthorized accesses to our information technology systems and infrastructure in the past, which may occur again in the future, our security measures have been able to detect, respond to and prevent any material adverse effect to our information systems and business operations from such breaches. However, in the future, any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, such as HIPPA, government enforcement actions and regulatory penalties. Unauthorized access, loss or dissemination could also disrupt our operations, including our ability to process samples, provide test results, bill payors or patients, provide customer support services, conduct research and development activities, process and prepare company financial information, manage various general and administrative aspects of our business and may damage our reputation, any of which could adversely affect our business, financial condition and results of operations.

If our current operating plan changes and we find that our existing capital resources will not meet our needs, we may find it necessary to raise additional funding, which may not be available.

We anticipate that our existing capital resources and expected net cash to be generated from sales of our molecular diagnostic tests will enable us to maintain our currently planned operations for the foreseeable future. However, we base this expectation on our current operating plan, which may change. We have incurred, and will continue to incur, significant costs in the discovery, development and marketing of current and prospective molecular diagnostic and companion diagnostic tests. Our

19

ongoing efforts to develop tests and expand our business which may be through internally developed products, in licensing and mergers and acquisitions will require substantial cash resources. If, due to changes in our current operating plan, adequate funds are not available, we may be required to raise additional funds. Sources of potential additional capital resources may include, but are not limited to, public or private equity financings, establishing a credit facility, or selling convertible or non-convertible debt securities. This additional funding, if necessary, may not be available to us on reasonable terms, or at all. If we issue shares of stock or other securities to acquire new companies or technologies, the ownership interests of our existing stockholders may be significantly diluted.

Because of our potential long-term capital requirements, we may access the public or private equity or debt markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. Under SEC rules, we currently qualify as a well-known seasoned issuer, or WKSI, and can at any time file a registration statement registering securities to be sold to the public which would become effective upon filing. If additional funds are raised by issuing equity securities, existing shareholders may suffer significant dilution. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances and licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies or tests, or grant licenses on terms that are not favorable to us.

Our business involves environmental risks that may result in liability for us.

In connection with our research and development activities, we are subject to federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, effluent discharge, handling and disposal of certain materials, biological specimens, chemicals and wastes. Although we believe that we have complied with the applicable laws, regulations and policies in all material respects and have not been required to correct any material noncompliance, we may be required to incur significant costs to comply with environmental and health and safety regulations in the future. Although we believe that our safety procedures for handling and disposing of controlled materials comply with the standards prescribed by state and federal regulations, accidental contamination or injury from these materials may occur. In the event of such an occurrence, we could be held liable for any damages that result and any such liability could exceed our resources.

Changes in health care policy could increase our costs, decrease our revenues and impact sales of and reimbursement for our tests.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act, or the ACA became law. This law substantially changes the way health care is financed by both governmental and private insurers, and significantly impacts our industry. The ACA contains a number of provisions that are expected to impact our business and operations, some of which in ways we cannot currently predict, including those governing enrollment in state and federal health care programs, reimbursement changes and fraud and abuse, which will impact existing state and federal health care programs and will result in the development of new programs.

In addition to the ACA, there will continue to be proposals by legislators at both the federal and state levels, regulators and private third-party payors to reduce costs while expanding individual healthcare benefits. Certain of these changes could impose additional limitations on the prices we will be able to charge for our tests or the amounts of reimbursement available for our tests from governmental agencies or private third-party payors.

We face risks associated with currency exchange rate fluctuations, which could adversely affect our operating results.

We receive a portion of our revenues and pay a portion of our expenses in currencies other than the United States dollar, such as the Euro, the Swiss franc, the British pound, the Australian dollar and the Canadian dollar. As a result, we are at risk for exchange rate fluctuations between such foreign currencies and the United States dollar, which could affect the results of our operations. If the U.S. dollar strengthens against foreign currencies, the translation of these foreign currency denominated transactions will result in decreased revenues and operating expenses. We may not be able to offset adverse foreign currency impact with increased revenues. We do not currently utilize hedging strategies to mitigate foreign currency risk and even if we were to implement hedging strategies to mitigate foreign currency risk, these strategies might not eliminate our exposure to foreign exchange rate fluctuations and would involve costs and risks of their own, such as ongoing management time and expertise, external costs to implement the strategies and potential accounting implications.

Risks Related to Commercialization of Our Tests, Our Services and Test Candidates

We generate most of our revenues from two products and we may not be able to maintain revenue growth and profitability.

We may not be able to generate is revenue growth or maintain existing revenue levels. Presently, our molecular diagnostic business operates profitably providing a cash contribution to our current funding and operational needs. We may not, however, be able to continue to operate our molecular diagnostic business on a profitable basis. We launched our first molecular diagnostic test, BRACAnalysis, our test for hereditary breast and ovarian cancer, in November 1996. BRACAnalysis test sales accounted for approximately one third of our revenues for the year ended June 30, 2015, and this percentage has been declining in recent years as we transition to our myRisk Hereditary Cancer test. An interruption or cessation of BRACAnalysis sample flow would have a material impact on our revenues and future profitability. In 2014 we launched our myRisk Hereditary Cancer test, which represents the next generation of our existing hereditary cancer franchise. We may not be successful in transitioning from our existing product portfolio to our new products, such as myRisk Hereditary Cancer Test, and in commercializing these tests over time. Other potential events or factors that may have a significant impact on our ability to sustain revenue growth and profitability for our molecular diagnostic business include the following:

• increased costs of reagents and other consumables required for molecular diagnostic testing;

• increased personnel and facility costs;

• our inability to hire competent, trained staff, including laboratory directors required to review and approve all reports we issue in our molecular diagnostic business, and sales personnel;

• our inability to obtain necessary equipment or reagents to perform molecular diagnostic testing;

• our inability to increase production capacity as demand increases;

• our inability to expand into new markets outside the United States;

• the efforts of third party payors to limit or decrease the amounts that they are willing to pay for our tests;

• increased licensing or royalty costs, and our ability to maintain and enforce the intellectual property rights underlying our tests and services;

• changes in intellectual propriety law applicable to our patents or enforcement in the United States and foreign countries;

• potential obsolescence of our tests;

• our inability to increase commercial acceptance of our molecular diagnostic tests;

• increased competition and loss of market share; and

• increased regulatory requirements.

Our international business exposes us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.

As part of our business strategy, we have expanded into international markets. We have established sales offices in Germany, Switzerland, France, Spain, the United Kingdom, Italy, Canada and Australia; laboratory operations in Germany; and international headquarters in Switzerland. We may establish additional operations or acquire additional properties outside the United States in order to advance our international sales doing business internationally involves a number of risks, including:

• failure by us to obtain regulatory approvals or adequate reimbursement for the use of our tests in various countries;

• difficulty in staffing and managing foreign operations;

• managing multiple payor reimbursement and self-pay systems;

• logistics and regulations associated with shipping patient samples, including infrastructure conditions and transportation delays;

• limits in our ability to penetrate international markets if we are not able to process tests locally;

• financial risks, such as longer payment cycles, difficulty collecting accounts receivable and exposure to foreign currency exchange rate fluctuations;

• political and economic instability, including wars, terrorism, and political unrest, outbreak of disease, boycotts, curtailment of trade and other business restrictions;

• multiple, conflicting and changing laws and regulations such as tax laws, export and import restrictions, employment laws, data and privacy laws, regulatory requirements and other governmental approvals, permits and licenses; and

21

• regulatory and compliance risks that relate to maintaining accurate information and control over sales and distributors’ activities that may fall within the purview of the U.S. Foreign Corrupt Practice Act, anti-boycott and other laws.

Any of these factors could significantly harm our international operations and, consequently, our revenues and results of operations. In addition, any failure to comply with applicable legal and regulatory obligations could impact us in a variety of ways that include, but are not limited to, significant criminal, civil and administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of shipments, and restrictions on certain business activities. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our distribution and sales activities.

Our international operations could be affected by changes in laws, trade regulations, labor and employment regulations, and procedures and actions affecting approval, production, pricing, reimbursement and marketing of tests, as well as by inter-governmental disputes. Any of these changes could adversely affect our business.

Our success internationally will depend, in part, on our ability to develop and implement policies and strategies that are effective in anticipating and managing these and other risks in the countries in which we do business. Failure to manage these and other risks may have a material adverse effect on our operations in any particular country and on our business as a whole.

Foreign governments may impose reimbursement standards, which may adversely affect our future profitability.

We market our tests in foreign jurisdictions and as such may be subject to rules and regulations in those jurisdictions relating to our testing. In some foreign countries, including countries in the European Union, the reimbursement of diagnostic tests is subject to governmental control. In these countries, reimbursement negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a test candidate. If reimbursement of our future tests is unavailable or limited in scope or amount, or if reimbursement rates are set at unsatisfactory levels, we may be unable to achieve or sustain profitability.

We may experience increased price competition and price erosion, including price decreases from CMS and private payors.

CMS has reduced the reimbursement rate for some of our products in the past and as a result we may experience further pricing pressures from managed care organizations and other private third-party payors in the future. Any declines in average selling prices of our products due to pricing pressures may have an adverse impact on our business, results of operations and financial condition.

Our pharmaceutical testing services customers may reduce the amount of testing they conduct through us.

If there is a change in the regulatory environment or intellectual property law, or our pharmaceutical testing services customers consolidate, our customers may divert resources from testing, resulting in a reduced demand for our laboratory testing services. Alternatively, customers may decide to perform their own laboratory testing services in-house.

We rely on a single laboratory facility to process each of our molecular diagnostic tests in the United States and Europe and a single laboratory facility to perform our pharmaceutical and clinical services. Failure to maintain the operations of these laboratories in compliance with applicable regulations would seriously harm our business.

We rely on a CLIA-certified laboratory facility in Salt Lake City, Utah to perform most of our molecular diagnostic tests; a CLIA-certified laboratory in South San Francisco, California to perform our VectraDA test; a single laboratory facility in Munich, Germany to perform our international molecular diagnostic tests; and a CLIA-certified laboratory facility in Austin, Texas to perform our pharmaceutical and clinical testing services. These facilities and certain pieces of laboratory equipment would be difficult to replace and may require significant replacement lead-time. In the event our clinical testing facilities were to lose their CLIA certification or other required certifications or licenses or were affected by a man-made or natural disaster, we would be unable to continue our molecular diagnostic and pharmaceutical and clinical services business at current levels to meet customer demands for a significant period of time. Although we maintain insurance on these facilities, including business interruption insurance, it may not be adequate to protect us from all potential losses if these facilities were damaged or destroyed. In addition, any interruption in our molecular diagnostic or pharmaceutical and clinical services business would result in a loss of goodwill, including damage to our reputation. If our molecular diagnostic or pharmaceutical and clinical services business were interrupted, it would seriously harm our business.

22

We depend on a limited number of third parties for some of our supplies of equipment and reagents. If these supplies become unavailable, then we may not be able to successfully perform our research or operate our business on a timely basis or at all.

We currently rely on a small number of suppliers to provide our gene sequencing equipment, content enrichment equipment, multiplex protein analysis equipment, robots, and specialty reagents and laboratory supplies required in connection with our testing and research. We believe that currently there are limited alternative suppliers of these equipment, robots, and reagents. The equipment, robots, or the reagents may not remain available in commercial quantities at acceptable costs. If we are unable to obtain when needed additional or alternative equipment, robots, or an adequate supply of reagents or other ingredients at commercially reasonable rates, our ability to continue to identify genes and perform molecular diagnostic testing and pharmaceutical and clinical services would be adversely affected.

Our molecular diagnostic and companion diagnostic tests in development may never achieve significant commercial market acceptance.

We may not succeed in achieving significant commercial market acceptance of our diagnostic test and clinical service offerings that we have launched in recent years or are currently developing. Our ability to successfully develop and commercialize our current molecular diagnostic and companion diagnostic tests, as well as any future molecular diagnostic and companion diagnostic tests that we may develop, will depend on several factors, including:

• our ability to convince the medical community of the clinical utility of our tests and their potential advantages over existing tests;

• our ability to collaborate with biotechnology and pharmaceutical companies to develop and commercialize companion diagnostic tests for their therapeutic drugs and drug candidates;

• the agreement by third-party payors to reimburse our tests, the scope and extent of which will affect patients’ willingness or ability to pay for our tests and will likely heavily influence physicians’ decisions to recommend our tests; and

• the willingness of physicians to utilize our tests, which can be difficult to interpret. This difficulty is caused by the ability of our tests to predict only as to a probability, not certainty, that a tested individual will develop, have the disease, benefit from a particular therapy or has an aggressive form of the disease that the test is intended to predict.

These factors present obstacles to commercial acceptance of our tests, which we would have to spend substantial time and money to overcome, if we can do so at all. Our inability to successfully do so would harm our business.

If we do not compete effectively with scientific and commercial competitors, we may not be able to successfully commercialize our tests.

The clinical laboratory and genetics testing fields are intense and highly competitive. Tests that are developed are characterized by rapid technological change. Our competitors in the United States and abroad are numerous and include, among others, major diagnostic companies, reference laboratories, molecular diagnostic firms, universities and other research institutions. Some of our potential competitors have considerably greater financial, technical, marketing and other resources than we do, which may allow these competitors to discover important genes and determine their function before we do. We could be adversely affected if we do not discover genes, proteins or biomarkers and characterize their function, develop molecular diagnostic and pharmaceutical and clinical services based on these discoveries, obtain required regulatory and other approvals and launch these tests and their related services before our competitors. We also expect to encounter significant competition with respect to any molecular diagnostic and companion diagnostic tests that we may develop or commercialize. Those companies that bring to market new molecular diagnostic and companion tests before we do may achieve a significant competitive advantage in marketing and commercializing their tests. We may not be able to develop additional molecular diagnostic tests successfully and we or our licensors may not obtain or enforce patents covering these tests that provide protection against our competitors. Moreover, our competitors may succeed in developing molecular diagnostic and companion diagnostic tests that circumvent our technologies or tests. Furthermore, our competitors may succeed in developing technologies or tests that are more effective or less costly than those developed by us or that would render our technologies or tests less competitive or obsolete. We expect competition to intensify in the fields in which we are involved as technical advances in these fields occur and become more widely known and changes in intellectual property laws generate challenges to our intellectual property position.

23

If our current research collaborators or scientific advisors terminate their relationships with us or develop relationships with a competitor, our ability to discover genes, proteins, and biomarkers, and to validate and commercialize molecular diagnostic and companion diagnostic tests could be adversely affected.

We have relationships with research collaborators at academic and other institutions who conduct research at our request. These research collaborators are not our employees. As a result, we have limited control over their activities and, except as otherwise required by our collaboration agreements, can expect only limited amounts of their time to be dedicated to our activities. Our ability to discover genes, proteins, and biomarkers involved in human disease and validate and commercialize molecular diagnostic and companion diagnostic tests will depend in part on the continuation of these collaborations. If any of these collaborations are terminated, we may not be able to enter into other acceptable collaborations. In addition, our existing collaborations may not be successful.

Our research collaborators and scientific advisors may have relationships with other commercial entities, some of which could compete with us. Our research collaborators and scientific advisors sign agreements which provide for the confidentiality of our proprietary information and the results of studies conducted at our request. We may not, however, be able to maintain the confidentiality of our technology and other confidential information related to all collaborations. The dissemination of our confidential information could have a material adverse effect on our business.

If we fail to retain our key personnel and hire, train and retain qualified employees and consultants, we may not be able to successfully continue our business.

Because of the specialized scientific nature of our business, we are highly dependent upon our ability to attract and retain qualified management, scientific and technical personnel. We are currently recruiting additional qualified management, scientific and technical personnel. Competition for such personnel is intense. Loss of the services of or failure to recruit additional key management, scientific and technical personnel would adversely affect our research and development programs and molecular diagnostic and pharmaceutical and clinical services business and may have a material adverse effect on our business as a whole.

Our agreements with our employees generally provide for employment that can be terminated by either party without cause at any time, subject to specified notice requirements. Further, the non-competition provision to which each employee is subject expires for certain key employees on the applicable date of termination of employment.

As we expand our commercial tests we may be required to incur significant costs and devote significant efforts to expand our existing tests sales and marketing capabilities.

Our sales and marketing experience and capabilities consist primarily of our sales force that markets our molecular diagnostic tests to oncologists, Ob/Gyns, urologists, dermatopathologists and rheumatologists in the United States. We are currently expanding our sales efforts outside the United States, which will require us to hire additional personnel and engage in additional sales and marketing efforts. We have limited sales and marketing experience outside the Unites States. As we expand our business operations internationally, we expect to face a number of additional costs and risks, including the need to recruit a large number of additional experienced marketing and sales personnel.

Risks Related to Our Intellectual Property

If we are not able to protect our proprietary technology, others could compete against us more directly, which would harm our business.

As of June 30, 2015, our patent portfolio included issued patents owned or licensed by us and numerous patent applications in the United States and other countries with claims covering our intellectual property rights. Our commercial success will depend, in part, on our ability to obtain additional patents and licenses and protect our existing patent position, both in the United States and in other countries, for compositions, processes, methods and other inventions that we believe are patentable. Our ability to preserve our trade secrets, proprietary data bases and other intellectual property is also important to our long-term success. If our intellectual property is not adequately protected, competitors may be able to use our technologies and erode or

24

negate any competitive advantage we may have, which could harm our business and ability to maintain profitability. Patents may also issue to third parties which could interfere with our ability to bring our molecular diagnostic tests to market. The laws of some foreign countries do not protect our proprietary rights to the same extent as U.S. laws, and we may encounter significant problems in protecting our proprietary rights in these countries.

The patent positions of diagnostic companies, including our patent position, are generally highly uncertain and involve complex legal and factual questions, and, therefore, any patents issued to us may be challenged, deemed unenforceable, invalidated or circumvented. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our proprietary technologies and any future tests are covered by valid and enforceable patents or are effectively maintained as trade secrets. Our patent applications may never issue as patents, and the claims of any issued patents may not afford meaningful protection for our technology or tests. In addition, any patents issued to us or our licensors may be challenged, and subsequently narrowed, invalidated or circumvented.

Where necessary, we may initiate litigation to enforce our patent or other intellectual property rights. Any such litigation may require us to spend a substantial amount of time and money and could distract management from our day-to-day operations. Moreover, there is no assurance that we will be successful in any such litigation.

The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:

• we or our licensors were the first to make the inventions covered by each of our patent applications;

• we or our licensors were the first to file patent applications for these inventions;

• any of our or our licensors’ patent applications will result in issued patents;

• any of our or our licensors’ patents will be valid or enforceable;

• any patents issued to us or our licensors and collaborators will provide a basis for commercially viable tests, will provide us with any competitive advantages or will not be challenged by third parties;

• we will develop additional proprietary technologies or tests that are patentable;

• the patents of others will not have an adverse effect on our business; or

• our patents or patents that we license from others will survive legal challenges, and remain valid and enforceable.

If a third party files a patent application with claims to subject matter we have invented, the PTO may declare interference between competing patent applications. If an interference is declared, we may not prevail in the interference. If the other party prevails in the interference, we may be precluded from commercializing services or tests based on the invention or may be required to seek a license. A license may not be available to us on commercially acceptable terms, if at all.

We also rely upon unpatented proprietary technologies and databases. Although we require employees, consultants and collaborators to sign confidentiality agreements, we may not be able to adequately protect our rights in such unpatented proprietary technologies and databases, which could have a material adverse effect on our business. For example, others may independently develop substantially equivalent proprietary information or techniques or otherwise gain access to our proprietary technologies or disclose our technologies to our competitors.

If we were sued for patent infringement by third parties, we might incur significant costs and delays in test introduction.

Our tests may also conflict with patents that have been or may be granted to others. Our industry includes many organizations that have or are seeking to discern biomarkers and develop genomic, proteomic and other technologies. To the extent any patents are issued or have been issued to those organizations, the risk increases that the sale of our molecular diagnostic and companion diagnostic tests currently being marketed or under development may give rise to claims of patent infringement. Others may have filed and in the future are likely to file patent applications covering biomarkers that are similar or identical to our tests. Any of these patent applications may have priority over our patent applications and these entities or persons could bring legal proceedings against us seeking damages or seeking to enjoin us from testing or marketing our tests. Patent litigation is costly, and even if we prevail, the cost of such litigation could have a material adverse effect on us. If the other parties in any such actions are successful, in addition to any liability for damages, we could be required to cease the infringing activity or obtain a license. Any license required may not be available to us on commercially acceptable terms, if at all. Our failure to obtain a license to any technology that we may require to commercialize our tests could have a material adverse effect on our business. We believe that there may be significant litigation in the industry regarding patent and other intellectual property rights. If we become involved in this litigation, it could consume a substantial portion of our managerial and financial resources.

25

We may be unable to adequately prevent disclosure of trade secrets, proprietary databases, and other proprietary information.

We rely on trade secrets to protect our proprietary technologies and databases, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and others to protect our trade secrets and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy if unauthorized disclosure of confidential information occurs. In addition, others may independently discover our trade secrets and proprietary information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our competitive position.

If we fail to comply with our obligations under license or technology agreements with third parties, we could lose license rights that are critical to our business.

We license intellectual property that is important to our business, including licenses underlying the technology in our molecular diagnostic and pharmaceutical and clinical services, and in the future we may enter into additional agreements that provide us with licenses to valuable intellectual property or technology. These licenses impose various royalty payments, milestones, and other obligations on us. If we fail to comply with any of these obligations, the licensor may have the right to terminate the license. Termination by the licensor would cause us to lose valuable rights, and could prevent us from distributing our current tests, or inhibit our ability to commercialize future test candidates. Our business would suffer if any current or future licenses terminate, if the licensors fail to abide by the terms of the license, if the licensors fail to prevent infringement by third parties, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter into necessary licenses on acceptable terms.

We may be subject to claims that we or our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is commonplace in our industry, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our potential competitors. Although no claims against us are currently pending, we may be subject to claims that these employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Risks Related to Government Regulation

If we fail to comply with the complex federal, state, local and foreign laws and regulations that apply to our business, we could suffer severe consequences that could materially and adversely affect our operating results and financial condition.

Our operations are subject to extensive federal, state, local and foreign laws and regulations, all of which are subject to change. These laws and regulations currently include, among other things:

• CLIA, which requires that laboratories obtain certification from the federal government, and state licensure laws;

• FDA laws and regulations;

• HIPAA, which imposes comprehensive federal standards with respect to the privacy and security of protected health information and requirements for the use of certain standardized electronic transactions; amendments to HIPAA under HITECH, which strengthen and expand HIPAA privacy and security compliance requirements, increase penalties for violators, extend enforcement authority to state attorneys general and impose requirements for breach notification;

• state laws regulating genetic testing and protecting the privacy of genetic test results, as well as state laws protecting the privacy and security of health information and personal data and mandating reporting of breaches to affected individuals and state regulators;

• the federal anti-kickback law, or the Anti-Kickback Statute, which prohibits knowingly and willfully offering, paying, soliciting, receiving, or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing, arranging for, or recommending of an item or service that is reimbursable, in whole or in part, by a federal health care program;

26

• the federal False Claims Act, which imposes liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment to the federal government;

• the federal Civil Monetary Penalties Law, which prohibits, among other things, the offering or transfer of remuneration to a Medicare or state health care program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a particular provider, practitioner, or supplier of services reimbursable by Medicare or a state health care program, unless an exception applies;

• other federal and state fraud and abuse laws, such as anti-kickback laws, prohibitions on self-referral, and false claims acts, which may extend to services reimbursable by any third-party payor, including private insurers;

• the federal Physician Payments Sunshine Act, which requires medical device manufactures to track and report to the federal government certain payments and other transfers of value made to physicians and teaching hospitals and ownership or investment interests held by physicians and their immediate family members;

• state laws that impose reporting and other compliance-related requirements; and

• similar foreign laws and regulations that apply to us in the countries in which we operate.

These laws and regulations are complex and are subject to interpretation by the courts and by government agencies. Our failure to comply could lead to civil or criminal penalties, exclusion from participation in state and federal health care programs, or prohibitions or restrictions on our laboratories’ ability to provide or receive payment for our services. We believe that we are in material compliance with all statutory and regulatory requirements, but there is a risk that one or more government agencies could take a contrary position, or that a private party could file suit under the qui tam provisions of the federal False Claims Act or a similar state law. Such occurrences, regardless of their outcome, could damage our reputation and adversely affect important business relationships with third parties, including managed care organizations, and other private third-party payors.

Failure to comply with government laws and regulations related to submission of claims for our services could result in significant monetary damages and penalties and exclusion from the Medicare and Medicaid programs and corresponding foreign reimbursement programs.

We are subject to laws and regulations governing the submission of claims for payment for our services, such as those relating to: coverage of our services under Medicare, Medicaid and other state, federal and foreign health care programs; the amounts that we may bill for our services; and the party to which we must submit claims. Our failure to comply with applicable laws and regulations could result in our inability to receive payment for our services or in attempts by state and federal healthcare programs, such as Medicare and Medicaid, to recover payments already made. Submission of claims in violation of these laws and regulations can result in recoupment of payments already received, substantial civil monetary penalties, and exclusion from state and federal health care programs, and can subject us to liability under the federal False Claims Act and similar laws. The failure to report and return an overpayment to the Medicare or Medicaid program within 60 days of identifying its existence can give rise to liability under the False Claims Act. Further, a government agency could attempt to hold us liable for causing the improper submission of claims by another entity for services that we performed if we were found to have knowingly participated in the arrangement at issue.

Our business could be harmed by the loss, suspension, or other restriction on a license, certification, or accreditation, or by the imposition of a fine or penalties, under CLIA, its implementing regulations, or other state, federal and foreign laws and regulations affecting licensure or certification, or by future changes in these laws or regulations.

The diagnostic testing industry is subject to extensive laws and regulations, many of which have not been interpreted by the courts. CLIA requires virtually all laboratories to be certified by the federal government and mandates compliance with various operational, personnel, facilities administration, quality and proficiency testing requirements intended to ensure that testing services are accurate, reliable and timely. CLIA certification is also a prerequisite to be eligible to bill state and federal health care programs, as well as many private third-party payors, for laboratory testing services. As a condition of CLIA certification, each of our laboratories is subject to survey and inspection every other year, in addition to being subject to additional random inspections. The biennial survey is conducted by CMS; a CMS agent (typically a state agency); or, if the laboratory holds a CLIA certificate of accreditation, a CMS-approved accreditation organization. Sanction for failure to comply with CLIA requirements, including proficiency testing violations, may include suspension, revocation, or limitation of a laboratory’s CLIA certificate, which is necessary to conduct business, as well as the imposition of significant fines or criminal penalties. In addition, we are subject to regulation under state laws and regulations governing laboratory licensure. Some states have

27

enacted state licensure laws that are more stringent than CLIA. We are also subject to laws and regulations governing our reference laboratory in Germany. Changes in state or foreign licensure laws that affect our ability to offer and provide diagnostic services across state or foreign country lines could materially and adversely affect our business. In addition, state and foreign requirements for laboratory certification may be costly or difficult to meet and could affect our ability to receive specimens from certain states or foreign countries.

Any sanction imposed under CLIA, its implementing regulations, or state or foreign laws or regulations governing licensure, or our failure to renew a CLIA certificate, a state or foreign license, or accreditation, could have a material adverse effect on our business. If the CLIA certificate of any one of our laboratories is revoked, CMS could seek revocation of the CLIA certificates of our other laboratories based on their common ownership or operation, even though they are separately certified.

Changes in the way that the FDA regulates tests performed by laboratories like ours could result in delay or additional expense in offering our tests and tests that we may develop in the future.

Historically, the FDA has exercised enforcement discretion with respect to most LDTs and has not required laboratories that furnish LDTs to comply with the agency’s requirements for medical devices (e.g., establishment registration, device listing, quality systems regulations, premarket clearance or premarket approval, and post-market controls). In recent years, however, the FDA has stated it intends to end its policy of general enforcement discretion and regulate certain LDTs as medical devices. To this end, on October 3, 2014, the FDA issued two draft guidance documents, entitled “Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)” and “FDA Notification and Medical Device Reporting for Laboratory Developed Tests (LDTs)”, respectively, that set forth a proposed risk-based regulatory framework that would apply varying levels of FDA oversight to LDTs. The FDA has indicated that it does not intend to modify its policy of enforcement discretion until the draft guidance documents are finalized. It is unclear at this time when, or if, the draft guidance documents will be finalized, and even then, the new regulatory requirements are proposed to be phased-in consistent with the schedule set forth in the guidance (in as little as 12 months after the draft guidance is finalized for certain high-priority LDTs such as LDTs with the same intended use as a cleared or approved companion diagnostic). Nevertheless, the FDA may decide to regulate certain LDTs on a case-by-case basis at any time, which could result in delay or additional expense in offering our tests and tests that we may develop in the future.

Companion diagnostic tests require FDA approval and we may not be able to secure such approval in a timely manner or at all.

Our companion diagnostic products, marketing, sales and development activities and manufacturing processes are subject to extensive and rigorous regulation by the FDA pursuant to the Federal Food, Drug, and Cosmetic Act (FDC Act), by comparable agencies in foreign countries, and by other regulatory agencies and governing bodies. Under the FDC Act, companion diagnostics must receive FDA clearance or approval before they can be commercially marketed in the U.S. The process of obtaining marketing approval or clearance from the FDA or by comparable agencies in foreign countries for new products could:

• take a significant period of time;

• require the expenditure of substantial resources;

• involve rigorous pre-clinical testing, as well as increased post-market surveillance;

• require changes to products; and

• result in limitations on the indicated uses of products.

Although we obtained FDA approval for our BRACAnalysisCDx test, which is used as a companion diagnostic to identify ovarian cancer patients who may benefit from AstraZeneca’s PARP inhibitor Lynparza™ (olaparib), we cannot predict whether or when we will be able to obtain FDA approval for other companion diagnostics that we are developing.

28

If the government and third-party payors fail to provide coverage and adequate payment for our tests and future tests, if any, our revenue and prospects for profitability will be harmed.

In both domestic and foreign markets, sales of our molecular diagnostic tests or any future diagnostic tests will depend in large part, upon the availability of reimbursement from third-party payors. Such third-party payors include state and federal health care programs such as Medicare, managed care providers, private health insurers and other organizations. These third-party payors are increasingly attempting to contain healthcare costs by demanding price discounts or rebates and limiting both coverage on which diagnostic tests they will pay for and the amounts that they will pay for new molecular diagnostic tests. We have recently experienced price reductions from CMS for some of our products and may experience future price reductions from managed care organizations and other third-party payors. The fact that a diagnostic test has been approved for reimbursement in the past, for any particular indication or in any particular jurisdiction, does not guarantee that such a diagnostic test will remain approved for reimbursement or that similar or additional diagnostic tests will be approved in the future. Moreover, there can be no assurance that any new tests we launch, such as myRisk Hereditary Cancer, myPath Melanoma and myPlan Lung Cancer, will be reimbursed at rates that are comparable to the rates that we historically obtained for our existing product portfolio. As a result, third-party payors may not cover or provide adequate payment for our current or future molecular diagnostic tests. Adequate third-party reimbursement might not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

U.S. and foreign governments continue to propose and pass legislation designed to reduce the cost of health care. For example, in some foreign markets, the government controls the pricing of many health care products. We expect that there will continue to be federal and state proposals to implement governmental controls or impose health care requirements. In addition, the Medicare program and increasing emphasis on managed care in the United States will continue to put pressure on product pricing. Cost control initiatives could decrease the price that we would receive for any tests in the future, which would limit our revenue and profitability.

Our business could be adversely impacted by the adoption of the ICD-10-CM Code Set.

CMS has adopted a new coding set for diagnoses, commonly known as ICD-10-CM, which significantly expands the current coding set. ICD-10-CM is currently required to be used on all claims with dates of service on or after October 1, 2015. We may be required to incur significant expense in implementing ICD-10-CM, and, if we do not adequately implement it, our business could be adversely impacted. In addition, if as a result of the new coding set, physicians fail to provide appropriate codes for desired tests, we may not be reimbursed for tests we perform.

Risks Related to Our Common Stock

Our stock price is highly volatile, and our stock may lose all or a significant part of its value.

The market prices for securities of molecular diagnostic companies have been volatile. This volatility has significantly affected the market prices for these securities for reasons frequently unrelated to the operating performance of the specific companies. These broad market fluctuations may adversely affect the market price of our common stock. The market price for our common stock has fluctuated significantly since public trading commenced in October 1995, and it is likely that the market price will continue to fluctuate in the future. In the two years ended June 30, 2015, our stock price has ranged from $20.02 per share to $42.50 per share. In addition, the stock market in general has experienced extreme price and volume fluctuations. Events or factors that may have a significant impact on our business and on the market price of our common stock include the following:

• failure of any of our recently launched tests and any new test candidates to achieve commercial success;

• failure to sustain revenue growth or margins in our molecular diagnostic business;

• changes in the structure of healthcare payment systems and changes in the governmental or private insurers reimbursement levels for our molecular diagnostic tests;

• introduction of new commercial tests or technological innovations by competitors;

• termination of the licenses underlying our molecular diagnostic and pharmaceutical and clinical services;

• delays or other problems with operating our laboratory facilities;

• failure of any of our research and development programs;

• changes in intellectual property laws of our patents or enforcement in the United States and foreign countries;

• developments or disputes concerning patents or other proprietary rights involving us directly or otherwise affecting the industry as a whole;

• missing or changing the financial guidance we provide;

29

• changes in estimates or recommendations by securities analysts relating to our common stock or the securities of our competitors;

• changes in the governmental regulatory approved process for our existing and new tests:

• failure to meet estimates or recommendations by securities analysts that cover our common stock;

• public concern over our approved tests and any test candidates;

• litigation;

• future sales or anticipated sales of our common stock by us or our stockholders;

• the timing and amount of repurchases of our common stock;

• general market conditions;

• seasonal slowness in sales, particularly in the quarters ending September 30 and March 31, the effects of which may be difficult to understand during periods of growth;

• celebrity publicity;

• economic, healthcare and diagnostic trends, disasters or crises and other external factors; and

• period-to-period fluctuations in our financial results.

These and other external factors may cause the market price and demand for our common stock to fluctuate substantially, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock. In addition, securities class action litigation against companies has been on the rise. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit regardless of the outcome. Such a lawsuit could also divert the time and attention of our management.

Anti-takeover provisions of Delaware law, provisions in our charter and bylaws and re-adoption of our stockholders’ rights plan, or poison pill, could make a third-party acquisition of us difficult.

Because we are a Delaware corporation, the anti-takeover provisions of Delaware law could make it more difficult for a third party to acquire control of us, even if the change in control would be beneficial to stockholders. We are subject to the provisions of Section 203 of the General Corporation Law of Delaware, which prohibits us from engaging in certain business combinations, unless the business combination is approved in a prescribed manner. In addition, our restated certificate of incorporation and restated bylaws also contain certain provisions that may make a third-party acquisition of us difficult, including:

• a classified board of directors, with three classes of directors each serving a staggered three-year term;

• the ability of the board of directors to issue preferred stock;

• a 70% super-majority shareholder vote to amend our bylaws and certain provisions of our certificate of incorporation; and

• the inability of our stockholders to call a special meeting or act by written consent.

In the past, we implemented a stockholders’ rights plan, also called a poison pill, which could make it uneconomical for a third party to acquire our company on a hostile basis. Although the plan expired in July 2011, our Board of Directors could adopt a new plan at any time. The provisions in a stockholders’ rights plan, as well as Section 203, may discourage certain types of transactions in which our stockholders might otherwise receive a premium for their shares over then current market price, and may limit the ability of our stockholders to approve transactions that they think may be in their best interests.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Our consolidated revenues consist primarily of sales of molecular diagnostic tests and pharmaceutical and clinical services through our wholly-owned subsidiaries Myriad Genetic Laboratories, Inc., Myriad Genetics GmbH, and Crescendo Bioscience, Inc. and our wholly-owned subsidiary Myriad RBM. During the year ended June 30, 2015, we reported total revenues of $723.1 million, net income of $80.2 million and diluted earnings per share of $1.08 that included income tax expense of $54.7 million.

In February 2015, we completed the acquisition of the Clinic located in Germany approximately 15 miles from the Company’s European laboratories for total consideration of $20.1 million. We believe acquisition of the Clinic should facilitate our penetration into the German molecular diagnostic market. The Clinic will allow us to directly negotiate reimbursement with government and private insurance providers in the German market and collaborate with hospitals and physician groups.

In February 2014, we completed the acquisition of privately-held Crescendo for $270.0 million in cash, which was reduced by the repayment of a loan made to Crescendo and other customary adjustments in accordance with the acquisition agreement. We believe that the acquisition of Crescendo facilitates our entry into the high growth autoimmune and inflammatory disease market, diversifies our product revenues and enhances our strength in protein-based diagnostics. The business of Crescendo, including its Vectra^®DA blood test for rheumatoid arthritis disease management, is operated as a wholly-owned subsidiary.

See Note 15 “Segment and Related Information” in the notes to our consolidated financial statements for information regarding our operating segments.

Our research and development expenses include costs incurred in formulating, improving, validating and creating alternative or modified processes related to and expanding the use of our current molecular diagnostic test offerings and costs incurred for the discovery, development and validation of our pipeline of molecular diagnostic and companion diagnostic candidates. Our research and development expense may fluctuate substantially from quarter to quarter depending on the number of clinical studies and the timing of samples supporting those clinical studies.

Our selling, general and administrative expenses include costs associated with growing our businesses domestically and internationally. Selling, general and administrative expenses consist primarily of salaries, commissions and related personnel costs for sales, marketing, customer service, billing and collection, legal, finance and accounting, information technology, human resources, and allocated facilities expenses. We expect that our selling, general and administrative expenses will continue to increase and that such increases may be substantial, depending on the number and scope of any new molecular diagnostic test launches, our efforts in support of our existing molecular diagnostic tests and pharmaceutical and clinical services as well as our continued international expansion efforts.

Results of Operations

Years ended June 30, 2015, 2014 and 2013

Revenue

	Years Ended June 30,						Change
(In millions)	2015		2014		2013		2015			2014
Revenue	$	723.1	$	778.2	$	613.2	$	(55.1	)	$	165.0

In 2015, the decrease in revenue was primarily driven by the loss of a one-time bolus of our BRACAnalysis revenue generated by celebrity publicity during the prior year, approximately $50.0 million. In addition, 2015 revenue was impacted by a $12.0 million loss of a contract with a payor and a $3.0 million decrease due to the reduction in Medicare reimbursement rates, offset by $29.7 million increase from the inclusion of sales of our VectraDA test for the full fiscal year.

38

In 2014, the increase in revenue was primarily driven by growth in hereditary cancer testing revenues of $148.8 million which included a one-time bolus generated by celebrity publicity. We believe that our increased sales, marketing, and education efforts resulted in wider acceptance of our molecular diagnostic tests by the medical community and increased patient testing volumes. In addition, there was a $14.0 million increase due to the inclusion of VectraDA following our acquisition of Crescendo in February 2014.

The following table presents additional detail regarding the composition of our total revenue:

	Years Ended June 30,						Change						% of Total Revenue
(In millions)	2015		2014		2013		2015			2014			2015			2014			2013

Cost of Sales

	Years Ended June 30,									Change
(In millions)	2015			2014			2013			2015		2014
Cost of Sales	$	147.4		$	109.2		$	79.7		$	38.2	$	29.5
Cost of sales as a % of Sales		20.4	%		14.0	%		13.0	%

In 2015, the increase in cost of sales was primarily driven by a $21.7 million increase in hereditary cancer costs which includes higher costs associated with the transition to myRisk as well as costs related to products for which we have not yet received reimbursement. In addition, there were $15.0 million of increased costs related to a full year of VectraDA and a increase of $1.5 million related to pharmaceutical and clinical services testing.

In 2014, the increase in cost of sales was primarily due to increases of $22.9 million related to hereditary cancer testing driven by increased test volumes and $8.6 million related to a partial year of VectraDA following the acquisition of Crescendo.

Research and Development Expenses

	Years Ended June 30,									Change
(In millions)	2015			2014			2013			2015		2014
R&D expense	$	75.5		$	67.5		$	53.7		$	8.0	$	13.8
R&D expense as a % of Sales		10.4	%		8.7	%		8.8	%

In 2015, the increase in R&D expense was primarily driven by the $9.2 million full-year impact of our R&D activities at Crescendo.

In 2014, the increase in R&D expense was primarily driven by $6.2 million due to the partial year impact of Crescendo. In addition there was a $7.6 million increase to improve current products and processes and support our pharmaceutical and clinical research business.

Selling, General and Administrative Expenses

	Years Ended June 30,									Change
(In millions)	2015			2014			2013			2015		2014
SG&A expense	$	366.0		$	327.1		$	251.8		$	38.9	$	75.3
SG&A expense as a % of Sales		50.6	%		42.0	%		41.1	%

In 2015, the increase in SG&A expense was primarily driven by the $24.8 million full year impact of Crescendo and $15.9 million in share-based compensation related to executive transition costs. In addition, SG&A expense increased by $16.8 million related to additional sales personnel for new products as well as $3.0 million associated with the Clinic acquisition. These were offset by a $14.5 million reduction in sales commissions and $7.7 million reduction in bad debt driven by decreased test revenue.

In 2014, the increase in SG&A expense consisted primarily of increases of $23.4 million related to the acquisition of Crescendo, $15.7 million of sales commission expense and $12.1 million for new sales and marketing initiatives. Also, expense increased in the year due to increases in administrative and legal expenses of $18.2 million and bad debt of $5.9 million driven by increased revenue.

Other Income

	Years Ended June 30,						Change
(In millions)	2015		2014		2013		2015			2014
Other Income	$	0.7	$	3.4	$	5.3	$	(2.7	)	$	(1.9	)

In 2015, the decrease in other income was primarily driven by the loss of interest income associated with the retirement of the note receivable from Crescendo, approximately $1.8 million. The remaining decrease was due primarily to reduced interest income driven by the decrease in the cash, cash equivalents and marketable investment securities balance. These decreases were partially offset by a $2.3 million increase in foreign exchange gains and disposition of assets.

In 2014, the decrease in other income was primarily due to the loss of interest income associated with the retirement of the note receivable from Crescendo in February 2014, approximately $0.9 million, and $1.0 million related to foreign exchange losses and the disposition of assets.

Income Tax Expense

	Years Ended June 30,									Change
(In millions)	2015			2014			2013			2015			2014
Income tax expense	$	54.7		$	101.6		$	86.1		$	(46.9	)	$	15.5
Effective tax rate		40.6	%		36.6	%		36.9	%

Our tax rate is a product of a U.S. federal effective rate of 35% and a blended state income tax rate of 2%. Certain significant or unusual items are separately recognized during the period in which they occur and can be a source of variability in the effective tax rates from period to period. The increase in the effective rate for the year ended June 30, 2015 as compared to the years ended June 30, 2014 and 2013 is due to an increase in our liability for unrecognized tax benefits, an increase in the valuation allowance attributable to state research credits and an adjustment in the deferred tax liability related to intangible assets acquired in 2011 (see Note 10 “Income Taxes” in the Notes to Consolidated Financial Statements). The effective rate was also negatively impacted by foreign losses for which no income tax benefit is recognized. The fiscal 2015 foreign losses, and the resulting impact on the effective rate, were larger in proportion to consolidated income as compared to earlier years. In 2014 the decrease was due to an increased tax benefit from stock-based compensation as a reduction of taxes payable.

Liquidity and Capital Resources

We believe that with our existing capital resources and expected net cash to be generated from sales, that we will have adequate funds to maintain our current and planned operations for the foreseeable future, although no assurance can be given that changes will not occur that would consume available capital resources more quickly than we currently expect and that we may need or want to raise financing.

The following table represents the balances of cash, cash equivalents and marketable investment securities:

	Years Ended June 30,						Change
(In millions)	2015		2014		2013		2015			2014
Cash and cash equivalents	$	64.1	$	64.8	$	104.1	$	(0.7	)	$	(39.3	)
Marketable investment securities		80.7		121.6		268.2		(40.9	)		(146.6	)
Long-term marketable investment securities		40.6		84.1		158.8		(43.5	)		(74.7	)
Cash, cash equivalents and marketable investment securities	$	185.4	$	270.5	$	531.1	$	(85.1	)	$	(260.6	)

In 2015, the decrease in cash, cash equivalents and marketable investment securities was primarily driven by the repurchase of $210.7 million of our common stock under our share repurchase program and the use of $20.1 million related to the acquisition of the Clinic. These uses of cash were offset by $140.5 million in cash flows from operating activities.

In 2014, the decrease in cash, cash equivalents and marketable investment securities was driven by the repurchase of $287.7 million of our common stock under our share repurchase programs and the use of $223.5 million for the acquisition of Crescendo. These were partially offset by $190.2 million in cash flows from operating activities and $64.8 million in net proceeds from common stock issued under the share-based compensation plans.

The following table represents the condensed cash flow statement:

	Years Ended June 30,									Change
(In millions)	2015			2014			2013			2015			2014

Cash and cash equivalents at the end of the year	$	64.1		$	64.8		$	104.1		$	(0.7	)	$	(39.3	)

Cash Flows from Operating Activities

In 2015, the primary driver of the reduction of cash flows from operating activities was the $96.0 million reduction of net income offset by increases in non-cash charges for depreciation and amortization as well as share-based compensation.

In 2014, the primary driver of the increase in cash flows from operating activities was the $29.0 million increase in net income.

Cash Flows from Investing Activities

In 2015, the increase in cash flows from investing activities was primarily related to the $203.4 million reduction in cash outlays related to acquisition activity offset by reduced net proceeds from the liquidation of marketable investment securities and increased capital expenditures.

In 2014, the increase of cash flows from investing activities was primarily driven the positive change in net purchases of marketable investments securities of $279.2 million. Cash flows from investing were negatively impacted by the $223.5 million acquisition of Crescendo.

41

Cash Flows from Financing Activities

In 2015, the increase in cash flows from financing activities was driven primarily by the $77.0 million reduction in repurchases and retirement of common stock from the prior year. Cash flows were negatively impacted by the reduction in net proceeds from common stock issued under share-based compensation plans of $34.8 million.

In 2014, the reduction in cash flows from financing activities was almost entirely driven by the increase in the repurchase and retirement of common stock of $141.4 million.

Contractual Obligations

The following table represents our contractual obligations as of June 30, 2015:

(In millions)	Total		Less Than 1 Year		1-3 Years		4-5 Years		More Than 5 Years
Purchase obligations	$	38.9	$	26.8	$	12.1	$	—	$	—
Operating Leases		64.0		12.4		19.2		12.5		19.9
Total		102.9		39.2		31.3		12.5		19.9

Purchase obligations are primarily related to Crescendo’s minimum unconditional purchase obligation of $33.4 million with a vendor to purchase goods and services used in the Company’s diagnostic processes. At the end of the year, there are approximately two years remaining under the initial term of the agreement. Also included in purchase obligations is $5.5 million in open purchase orders.

The expected timing of payment for the obligations listed above is estimated based on current information. Actual payment timing and amounts may differ depending on the timing of goods or services received or other changes. The table above only includes payment obligations that are fixed or determinable. The table excludes royalties to third parties based on future sales of any of our product candidates that are approved for sale, as the amounts, timing, and likelihood of any such payments are based on the level of future sales of tests and are unknown.

Effects of Inflation

We do not believe that inflation has had a material impact on our business, revenues, or operating results during the periods presented.

Off-Balance Sheet Arrangements

None.

Certain Factors That May Affect Future Results of Operations

The Securities and Exchange Commission encourages companies to disclose forward-looking information so that investors can better understand a company’s future prospects and make informed investment decisions. This Annual Report on Form 10-K contains such “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

Words such as “may,” “anticipate,” “estimate,” “expects,” “projects,” “intends,” “plans,” “believes,” “seek,” “could,” continue,” “likely,” “will,” “strategy, “goal” and words and terms of similar substance used in connection with any discussion of future operating or financial performance, identify forward-looking statements. All forward-looking statements are management’s present expectations of future events and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those described in the forward-looking statements. These risks include, but are not limited to: the risk that sales and profit margins of our existing molecular diagnostic tests and pharmaceutical and clinical services may decline or will not continue to increase at historical rates; risks related to our ability to transition from our existing product portfolio to our new tests; risks related to changes in the governmental or private insurers reimbursement levels for our tests or our ability to obtain reimbursement for our new tests at comparable levels to our existing tests; risks related to increased competition and the development of new competing tests and services; the risk that we may be unable to develop or

42

achieve commercial success for additional molecular diagnostic tests and pharmaceutical and clinical services in a timely manner, or at all; the risk that we may not successfully develop new markets for our molecular diagnostic tests and pharmaceutical and clinical services, including our ability to successfully generate revenue outside the United States; the risk that licenses to the technology underlying our molecular diagnostic tests and pharmaceutical and clinical services tests and any future tests are terminated or cannot be maintained on satisfactory terms; risks related to delays or other problems with operating our laboratory testing facilities; risks related to public concern over our genetic testing in general or our tests in particular; risks related to regulatory requirements or enforcement in the United States and foreign countries and changes in the structure of the healthcare system or healthcare payment systems; risks related to our ability to obtain new corporate collaborations or licenses and acquire new technologies or businesses on satisfactory terms, if at all; risks related to our ability to successfully integrate and derive benefits from any technologies or businesses that we license or acquire; risks related to our projections about the potential market opportunity for our products; the risk that we or our licensors may be unable to protect or that third parties will infringe the proprietary technologies underlying our tests; the risk of patent-infringement claims or challenges to the validity of our patents; risks related to changes in intellectual property laws covering our molecular diagnostic tests and pharmaceutical and clinical services and patents or enforcement in the United States and foreign countries, such as the Supreme Court decision in the lawsuit brought against us by the Association for Molecular Pathology et al; risks of new, changing and competitive technologies and regulations in the United States and internationally; and other factors discussed under the heading “Risk Factors” contained in Item 1A of this Annual Report.

In light of these assumptions, risks and uncertainties, the results and events discussed in the forward-looking statements contained in this Annual Report or in any document incorporated by reference might not occur. Stockholders are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this Annual Report. We are not under any obligation, and we expressly disclaim any obligation, to update or alter any forward-looking statements, whether as a result of new information, future events or otherwise. All subsequent forward-looking statements attributable to us or to any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

Market, Industry and Other Data

This Annual Report on Form 10-K contains estimates, projections and other information concerning our industry, our business and relevant molecular diagnostics markets, including data regarding the estimated size of relevant molecular diagnostic markets, patient populations, and the perceptions and preferences of patients and physicians regarding certain therapies, as well as data regarding market research and estimates. Information that is based on estimates, forecasts, projections, market research or similar methodologies is inherently subject to uncertainties and actual events or circumstances may differ materially from events and circumstances that are assumed in this information. Unless otherwise expressly stated, we obtained this industry, business, market and other data from reports, research surveys, studies and similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources that we believe to be reliable. In some cases, we do not expressly refer to the sources from which this data is derived. In that regard, when we refer to one or more sources of this type of data in any paragraph, you should assume that other data of this type appearing in the same paragraph is derived from the same sources, unless otherwise expressly stated or the context otherwise requires.

Critical Accounting Policies

Critical accounting policies are those policies which are both important to the portrayal of a company’s financial condition and results and require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies are as follows:

• revenue recognition;

• allowance for doubtful accounts;

• goodwill; and

• income taxes.

Revenue Recognition. Revenue includes the sale of our molecular diagnostic tests and of our pharmaceutical and clinical services. Revenue is recorded at the invoiced amount net of any discounts or allowances and is recognized when persuasive evidence of an agreement exists, delivery has occurred, the fee is fixed or determinable, and collection is reasonably assured. Revenue is recognized upon completion of the test or service, communication of results, and when collectability is reasonably assured.

43

Allowance for Doubtful Accounts. The preparation of our financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amount of assets at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Trade accounts receivable are comprised of amounts due from sales of our molecular diagnostic tests, which are recorded net of any discounts or contractual allowances. We analyze trade accounts receivable and consider historic experience, customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms when evaluating the adequacy of the allowance for doubtful accounts.

We periodically evaluate and adjust the allowance for doubtful accounts when trends or significant events indicate that a change in estimate is appropriate. Such changes in estimate could materially affect our results of operations or financial position; however, to date these changes have not been material. It is possible that we may need to adjust our estimates in future periods.

After a review of our allowance for doubtful accounts as of June 30, 2015 and 2014, we have determined that a hypothetical ten percent increase in our allowance for doubtful accounts would result in additional bad debt expense and an increase to our allowance for doubtful accounts of $0.8 million and $0.9 million, respectively.

Goodwill. We test goodwill for impairment on an annual basis and in the interim by reporting unit if events and circumstances indicate that goodwill may be impaired. The events and circumstances that are considered include business climate and market conditions, legal factors, operating performance indicators and competition. Impairment of goodwill is evaluated on a qualitative basis to determine if using a two-step process is necessary. If the qualitative assessment suggests that impairment is more likely than not, a two-step impairment analysis is performed. The first step involves comparison of the fair value of a reporting unit with its carrying amount. The valuation of a reporting unit requires judgment in estimating future cash flows, discount rates and other factors. In making these judgments, we evaluate the financial health of our business, including such factors as industry performance, market saturation and opportunity, changes in technology and operating cash flows. Changes in our forecasts or decreases in the value of our common stock could cause book value of reporting units to exceed their fair values. If the carrying amount of a reporting unit exceeds its fair value, the second step of the process involves a comparison of the fair value and the carrying amount of the goodwill of that reporting unit. If the carrying amount of the goodwill of the reporting unit exceeds the fair value of that goodwill, an impairment loss would be recognized in an amount equal to the excess of carrying value over fair value. If an event occurs that would cause a revision to the estimates and assumptions used in analyzing the value of the goodwill, the revision could result in a non-cash impairment charge that could have a material impact on the financial results.

We have recorded goodwill of $177.2 million from the acquisitions of the Clinic that was completed on February 27, 2015, Crescendo that was completed on February 28, 2014 and Myriad RBM that was completed on May 31, 2011. Of this goodwill, $112.3 million for Crescendo relates to our molecular diagnostic segment and $64.9 million for Myriad RBM and the Clinic relate to our other segment. We evaluated the Clinic reporting unit for impairment noting no indicators of impairment from the date of acquisition. We also measured the fair value of the Crescendo and Myriad RBM reporting units utilizing income and market approaches. The income approach considered management’s business plans and projections as the basis for expected cash flows for the next twelve years and a 4.0% residual growth rate thereafter for both units. We also used a weighted average discount rate of 25% for Myriad RBM and 15.5% for Crescendo for the analysis. Other significant estimates used in the analysis include the profitability of the respective reporting unit and working capital effects of each unit. We noted the fair value of the Myriad RBM and Crescendo reporting units exceeded their carrying value by 135% and 13% respectively using these assumptions mentioned.

Income Taxes. Our income tax provision is based on income before taxes and is computed using the liability method in accordance with Accounting Standards Codification (“ASC”) 740—Income Taxes. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using tax rates projected to be in effect for the year in which the differences are expected to reverse. Significant estimates are required in determining our provision for income taxes. Some of these estimates are based on interpretations of existing tax laws or regulations, or the expected results from any future tax examinations. Various internal and external factors may have favorable or unfavorable effects on our future provision for income taxes. Those factors include, but are not limited to, changes in tax laws, regulations and/or rates, the results of any future tax examinations, changing interpretations of existing tax laws or regulations, changes in estimates of prior years’ items, past levels of research and development spending, acquisitions, changes in our corporate structure, and changes in overall levels of income before taxes all of which may result in periodic revisions to our provision for income taxes.

44

Developing our provision for income taxes, including our effective tax rate and analysis of potential uncertain tax positions, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and any estimated valuation allowance we deem necessary to offset deferred tax assets. If we do not maintain taxable income from operations in future periods, we may increase the valuation allowance for our deferred tax assets and record material adjustments to our income tax expense. Our judgment and tax strategies are subject to audit by various taxing authorities. While we believe we have provided adequately for our uncertain income tax positions in our consolidated financial statements, adverse determination by these taxing authorities could have a material adverse effect on our consolidated financial condition, results of operations or cash flows. Interest and penalties on income tax items are included as a component of overall income tax expense.

Recent Accounting Pronouncements

In May, 2015, the Financial Accounting Standards Board issued ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and which should be applied retrospectively to all periods presented. Earlier application is permitted. The new amendment removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient. In addition, the amendments remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers.” Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. In July 2015, the FASB voted to defer the effective date by one year to December 15, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. Companies may use either a full retrospective or a modified retrospective approach to adopt the standard. We are currently evaluating the impact, if any, the adoption of this standard will have on our consolidated financial statements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We maintain an investment portfolio in accordance with our written investment policy. The primary objectives of our investment policy are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. Our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure to any single issue, issuer or type of investment.

Our investments consist of securities of various types and maturities of five years or less, with a maximum average maturity of three years. These securities are classified as available for sale. Available-for-sale securities are recorded on the balance sheet at fair market value with unrealized gains or losses reported as part of accumulated other comprehensive income/loss. Realized gains and losses on investment security transactions are reported on the specific-identification method. Dividend and interest income are recognized when earned. A decline in the market value of any available-for-sale security below cost that is deemed other-than-temporary results in a charge to earnings and establishes a new cost basis for the security.

Although our investment policy guidelines are intended to ensure the preservation of principal, market conditions can result in high levels of uncertainty. Our ability to trade or redeem the marketable investment securities in which we invest, including certain corporate bonds, may become difficult. Valuation and pricing of these securities can also become variable and subject to uncertainty.

As of June 30, 2015 our amortized cost of investment securities is equal to the fair value. For the year ended June 30, 2015 we have experienced fluctuations in our portfolio value primarily from our investments in bonds of various municipalities. If interest rates rise, the market value of our investments may decline, which could result in a realized loss if we are forced to sell an investment before its scheduled maturity. A hypothetical increase in interest rates by 25 basis points would have resulted in a decrease in the fair value of our net investment position of approximately $0.5 million and $0.7 million as of June 30, 2015 and 2014, respectively. We do not utilize derivative financial instruments to manage our interest rate risks.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Myriad Genetics, Inc.

We have audited the accompanying consolidated balance sheets of Myriad Genetics, Inc. and subsidiaries as of June 30, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended June 30, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Myriad Genetics, Inc. and subsidiaries at June 30, 2015 and 2014, and the consolidated results of their operations and their cash flows for each of the three years in the period ended June 30, 2015, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars and shares in millions, except per share data)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Financial Statement Presentation

Myriad Genetics, Inc. and subsidiaries (collectively, the Company) is a leading molecular diagnostic company focused on developing and marketing novel predictive medicine, personalized medicine and prognostic medicine tests. The Company employs a number of proprietary technologies, including DNA, RNA and protein analysis, that help it to understand the genetic basis of human disease and the role that genes and their related proteins may play in the onset and progression of disease. The Company uses this information to guide the development of new molecular diagnostic and companion diagnostic tests that are designed to assess an individual’s risk for developing disease later in life (predictive medicine), identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment (personalized medicine), or assess a patient’s risk of disease progression and disease recurrence (prognostic medicine). The Company generates revenue by performing molecular diagnostic tests as well as by providing pharmaceutical and clinical services to the pharmaceutical and biotechnology industries and medical research institutions utilizing its multiplexed immunoassay technology. The Company’s corporate headquarters is located in Salt Lake City, Utah.

The consolidated financial statements of the Company are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with U.S. GAAP. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. A reclassification of $0.6 and $0.7 from proceeds from maturities and sales of marketable securities was made to reflect the effect of foreign exchange rates on cash and cash equivalents in the condensed consolidated statement of cash flows and for the fiscal year ended June 30, 2014 and 2013 respectively, and a reclassification of $0.6 from other receivables to trade accounts receivable in the condensed consolidated balance sheet for fiscal year ended June 30, 2014 to conform to the current-year presentation.

Marketable Investment Securities

The Company has classified its marketable investment securities as available-for-sale. Available-for-sale investment securities with remaining maturities of greater than one year are classified as long-term. Available-for-sale investment securities with remaining maturities of less than one year are classified as short-term. Available-for-sale investment securities with remaining maturities of less than three months at the time of purchase are classified as cash equivalents. Marketable securities are carried at estimated fair value with unrealized holding gains and losses, net of the related tax effect, included in accumulated other comprehensive (loss) in stockholders’ equity until realized. Gains and losses on investment security transactions are reported using the specific-identification method. Dividend and interest income are recognized when earned.

A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and establishes a new cost basis for the security. Losses are charged against “Other income” when a decline in fair value is determined to be other than temporary. We review several factors to determine whether a loss is other than temporary. These factors include but are not limited to: (i) the extent to which the fair value is less than cost and the cause for the fair value decline, (ii) the financial condition and near term prospects of the issuer, (iii) the length of time a security is in an unrealized loss position and (iv) our ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. There were no other-than-temporary impairments recognized during the fiscal years ended June 30, 2015, 2014 and 2013.

53

Inventory

Inventories consist of reagents, plates and testing kits. Inventories are stated at the lower of cost or market on a first-in, first-out basis. In order to assess the ultimate realization of inventories, the Company is required to make judgments as to future demand requirements compared to current or committed inventory levels.

The Company evaluates its inventories for excess quantities and obsolescence. Inventories that are considered obsolete are expensed. The valuation of inventories requires the use of estimates as to the amounts of current inventories that will be sold. These estimates are dependent on management’s assessment of current and expected orders from the Company’s customers.

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are comprised of amounts due from sales of the Company’s molecular diagnostic tests and pharmaceutical and clinical services and are recorded at the invoiced amount, net of discounts and contractual allowances. The allowance for doubtful accounts is based on the Company’s best estimate of the amount of probable losses in the Company’s existing accounts receivable, which is based on historical write-off experience, customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers and does not require collateral.

Property, Plant and Equipment

Equipment and leasehold improvements are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method based on the lesser of estimated useful lives of the related assets or lease terms. Equipment items have depreciable lives of five to seven years. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the associated lease terms, which range from three to fifteen years. Repairs and maintenance costs are charged to expense as incurred.

Intangible Assets and Other Long-Lived Assets

Intangible and other long-lived assets are comprised of acquired licenses and intellectual property and purchased in-process research and development. Acquired intangible assets are recorded at fair value and amortized over the shorter of the contractual life or the estimated useful life. The estimated useful life of acquired in-process research and development was also evaluated in conjunction with the annual impairment analysis of intangible assets. The classification of the acquired in-process research and development as an indefinite lived asset was deemed appropriate as the related research and development was not yet complete nor had it been abandoned.

The Company continually reviews and monitors long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Goodwill

Goodwill is tested for impairment on an annual basis as of April 1 and in the interim by reporting unit if events and circumstances indicate that goodwill may be impaired. The events and circumstances that are considered include business climate and market conditions, legal factors, operating performance indicators and competition. Impairment of goodwill was evaluated using a two-step process. The first step involves a comparison of the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the fair value and the carrying amount of the goodwill of that reporting unit. If the carrying amount of the goodwill of the reporting unit exceeds the fair value of that goodwill, an impairment loss would be recognized in an amount equal to the excess of carrying value over fair value. If an event occurs that would cause a revision to the estimates and assumptions used in analyzing the value of the goodwill, the revision could result in a non-cash impairment charge that could have a material impact on the financial results.

54

Revenue Recognition

Molecular diagnostic testing revenue is recognized when persuasive evidence of an agreement exists, results have been communicated to the patient, the fee is fixed or determinable, and collection is reasonably assured. Revenue from the sale of molecular diagnostic tests and related marketing agreements is recorded at the invoiced amount net of any discounts or contractual allowances.

Pharmaceutical and clinical service revenue is recognized when persuasive evidence of an agreement exists, the fee is fixed and or determinable, when the service has been completed and the results of the tests/service are provided to the customer, and collectability is reasonably assured. In addition, the Company’s wholly owned subsidiary, Myriad RBM, has received national, state, foreign government and private foundation grants and contracts. Revenue associated with these grants and contracts is recognized in the period in which qualifying costs for the services by the grants and contracts are incurred and the related grant or contract fee is earned.

Income Taxes

The Company recognizes income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities.

The provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and any estimated valuation allowances deemed necessary to recognize deferred tax assets at an amount that is more likely than not to be realized. The Company’s filings, including the positions taken therein, are subject to audit by various taxing authorities. While the Company believes it has provided adequately for its income tax liabilities in the consolidated financial statements, adverse determinations by these taxing authorities could have a material adverse effect on the consolidated financial condition, results of operations or cash flows.

Earnings Per Share

Basic earnings per share is computed based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share is computed based on the weighted-average number of shares of common stock, including the dilutive effect of common stock equivalents, outstanding.

The following is a reconciliation of the denominators of the basic and diluted earnings per share computations:

	Years Ended June 30,
	2015		2014		2013
Denominator:
Weighted-average shares outstanding used to compute basic EPS		71.3		75.7		80.9
Effect of dilutive stock options		3.2		2.5		2.4
Weighted-average shares outstanding and dilutive securities used to compute diluted EPS		74.5		78.2		83.3

Certain outstanding options and RSUs were excluded from the computation of diluted earnings per share because the effect would have been anti-dilutive. These potential dilutive common shares, which may be dilutive to future diluted earnings per share, are as follows:

	Years Ended June 30,
	2015		2014		2013
Anti-dilutive options and RSUs excluded from EPS computation		—		—		—

55

Foreign Currency

The functional currency of the Company’s international subsidiaries is the local currency. For those subsidiaries, expenses denominated in the functional currency are translated into U.S. dollars using average exchange rates in effect during the period and assets and liabilities are translated using period-end exchange rates. The foreign currency translation adjustments are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ (deficit) equity.

The following table shows the cumulative translation adjustments included in other comprehensive income, net of tax:

Balance at June 30, 2014	$	(1.8	)
Period translation adjustments		(5.2	)
Ending balance June 30, 2015		(7.0	)

Use of Estimates

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires Company management to make estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount of fixed assets, valuation allowances for receivables and deferred income tax assets, certain accrued liabilities, share-based compensation and impairment analysis of goodwill and intangible assets. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In May, 2015, the Financial Accounting Standards Board issued ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and which should be applied retrospectively to all periods presented. Earlier application is permitted. The new amendment removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient. In addition, the amendments remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers.” Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. It is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. We are currently evaluating the impact, if any, the adoption of this standard will have on our consolidated financial statements.

2. BUSINESS ACQUISITIONS

German Clinic

On February 27, 2015, the Company completed the acquisition of privately-held Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG (the “Clinic”) approximately 15 miles from the Company’s European laboratories in Munich, Germany. The cash paid and preliminary total consideration transferred to acquire the Clinic was $20.1.

Total consideration transferred was allocated to tangible assets acquired and liabilities assumed based on their preliminary fair values at the acquisition date as set forth below. The Company believes acquisition of the Clinic may facilitate the Company’s penetration into the German molecular diagnostic market. The Clinic will allow the Company to directly negotiate reimbursement with government and private insurance providers for our tests in the German market and collaborate with hospitals and physician groups. These factors contributed to consideration transferred in excess of the fair value of the Clinic’s net tangible and intangible assets acquired, resulting in the Company recording goodwill in connection with the transaction. Under German tax law the goodwill related to the purchase of the clinic is deductible and will be amortized for tax purposes over 15 years.

Management estimated the fair value of tangible and intangible assets and liabilities in accordance with the applicable accounting guidance for business combinations and utilized the services of third-party valuation consultants. The preliminary allocation of the consideration transferred is subject to potential adjustments primarily due to tax-related matters, including tax basis of acquired assets and liabilities in the foreign jurisdiction, and third party valuations of acquired assets and liabilities, including actuarial analysis of pension assets and liabilities and fair value of equipment. During the measurement period, the Company may record adjustments to the provisional amounts recognized in the Company’s initial accounting for the acquisition. The Company expects the allocation of the consideration transferred to be final within the measurement period (up to one year from the acquisition date).

	Estimated Fair Value
Current assets	$	3.1
Real property		20.7
Equipment		1.6
Goodwill		8.1
Current liabilities		(4.4	)
Long-term liabilities		(9.0	)
Total purchase price	$	20.1

56

During the current period there were adjustments to long-term liabilities, deferred grants and goodwill. The long-term liabilities increased by approximately $2.0 due to information obtained from the third party actuary analysis of the pension obligation which increased goodwill for further information on the pension see Note 8. The deferred grants fair value was determined to be $0.0 by management. This fair value adjustment decreased the deferred grants to $0.0 and decreased goodwill by $10.7.

Crescendo Bioscience, Inc.

On February 28, 2014, the Company completed the acquisition of privately-held Crescendo Bioscience, Inc. (“Crescendo”), pursuant to an Amended and Restated Agreement and Plan of Merger, dated February 2, 2014 (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, Myriad acquired Crescendo for total consideration of $259.0 as detailed below, by means of a reverse triangular merger in which Crescendo survived the merger as the surviving corporation and a wholly-owned subsidiary of Myriad. The surviving corporation operates under the name Crescendo Bioscience, Inc.

The following table reconciles consideration transferred to the total cash paid to acquire Crescendo:

Total consideration transferred	$	259.0
Share-based compensation to Crescendo employees		6.9
Change of control payments to Crescendo employees		5.7
Offset: Non-cash fair value purchase option		(8.0	)
Total cash paid	$	263.6

The total consideration of $259.0 consisted of (i) $225.1 in cash, (ii) $25.9 in elimination of intercompany balances related to accrued interest and the term loan the Company issued to Crescendo on September 8, 2011, and (iii) $8.0 related to the fair value of the purchase option granted to the Company on September 8, 2011 by Crescendo through a definitive merger agreement (“Option Agreement”) entered into in association with the term note. Of the cash consideration, $20.0 was deposited into an escrow account to fund (i) any post-closing adjustments payable to Myriad based upon differences between the estimated working capital and the actual working capital of Crescendo at closing, and (ii) any indemnification claims made by Myriad against Crescendo, for a period of time, based upon the completion of an audit of Crescendo’s financial statements, of no fewer than twelve nor more than fifteen months following closing.

Of the total cash paid, $6.9 was accounted for as share-based compensation expense resulting from the accelerated vesting of employee options immediately prior to the acquisition and $5.7 was accounted for as change of control bonuses paid to Crescendo employees and directors. The Company recognized the share-based compensation expense and change of control bonuses in post-acquisition Consolidated Statements of Comprehensive Income for the year ended June 30, 2014.

Total consideration transferred was allocated to tangible and identifiable intangible assets acquired and liabilities assumed based on their preliminary fair values at the acquisition date as set forth below. The Company believes that the acquisition of Crescendo facilitates the Company’s entry into the high growth autoimmune market, diversifies its product revenue and enhances its strength in protein-based diagnostics. These factors contributed to consideration transferred in excess of the fair value of Crescendo’s net tangible and intangible assets acquired, resulting in the Company recording goodwill in connection with the transaction.

The Company’s allocation of consideration transferred for Crescendo is as follows:

	Estimated Fair Value
Other assets acquired	$	15.9
Intangible assets		196.6
Goodwill		112.3
Total assets acquired		324.8
Deferred tax liabilities		44.2
Other liabilities assumed		21.6
Total net assets acquired	$	259.0

5. GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company has recorded goodwill of $177.2 from the acquisitions of Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG that was completed on February 27, 2015, Crescendo Bioscience, Inc. that was completed on February 28, 2014 and Rules-Based Medicine, Inc. that was completed on May 31, 2011. Of this goodwill, $112.3 relates to the Company’s diagnostic segment and $64.9 related to the other segment. The Company assessed goodwill for impairment in accordance with the appropriate guidance (see Note 1) and recorded no impairment of goodwill for the period ended June 30, 2015. Included in the other segment is $8.0 in goodwill associated with the acquisition of the Clinic which is preliminary and subject to adjustment within the measurement period (see Note 2). The following summarizes changes to the goodwill balance for the years ended June 30, 2015 and 2014:

Intangible Assets

Intangible assets primarily consist of amortizable assets of purchased licenses and technologies, developed technology, a laboratory database, trademarks, and customer relationships as well as non-amortizable intangible assets of in-process technologies, research and development. Certain of these intangible assets were recorded as part of the Company’s purchase of Crescendo on February 28, 2014 and Myriad RBM on May 31, 2011. The Company’s developed technology and database acquired have estimated remaining useful lives of 16 years, trademarks acquired in have an estimated remaining useful life of approximately 13 years and customer relationships have an estimated remaining useful life of approximately 6 years. The estimated useful life of acquired in-process research and development was also evaluated in conjunction with the annual impairment analysis of intangible assets. The classification of the acquired in-process research and development as an indefinite lived asset was deemed appropriate as the related research and development was not yet complete nor had it been abandoned. In December 2012, the Company notified the licensor of the Company’s OnDose product of the Company’s intent to terminate the license agreement, and as a result, recorded an impairment charge of approximately $1.5 associated with the purchased license agreement. Other than this $1.5 impairment charge, the Company concluded there was no impairment of long-lived assets for the years ended June 30, 2015, 2014 and 2013.

The following summarizes the amounts reported as intangible assets:

	Gross Carrying Amount		Accumulated Amortization			Net
At June 30, 2015:

Total unamortized intangible assets		4.8		—			4.8
Total intangible assets	$	213.6	$	(8.3	)	$	205.3

As of June 30, 2015 the weighted average remaining amortization period for purchased licenses and technologies, trademarks, and customer relationships is approximately 15 years.

The Company recorded amortization during the respective periods for these intangible assets as follows:

	Years Ended June 30,
	2015		2014		2013
Amortization on intangible assets	$	12.7	$	4.6	$	0.9

Amortization expense of intangible assets is estimated to be $12.5 in 2016, $12.5 in 2017, $12.5 in 2018, $12.5 in 2019 and $12.2 in 2020 and $125.6 thereafter.

6. COST BASIS INVESTMENT

In April 2013, the Company acquired approximately 28 shares of Series E preferred stock of RainDance Technologies, Inc. (“RainDance”) of Lexington, Massachusetts, for $5.0. RainDance provides high-throughput picodroplet-based technology that can encapsulate a single molecule, cell or reaction and be digitally analyzed and sorted one at a time. The Series E shares purchased by the Company represented less than 5% of the total shares outstanding of RainDance’s capital stock. Subsequent to the investment the Company evaluated its relationship with RainDance and determined it did not have significant influence over the operations of RainDance. The Company’s investment in RainDance has been recorded under the cost method as an “Other Asset” on the Company’s consolidated balance sheet. The Company periodically evaluates the investment for impairment. No impairment indicators were noted at June 30, 2015.

The Company has two non-contributory defined benefit pension plans for its current and former Clinic employees. The Company has closed participation in the plans to exclude those employees hired after 2002. As of June 30, 2015 the fair value of the plan assets were approximately $0.2 resulting in a net pension liability of $4.9.

9. PREFERRED AND COMMON STOCKHOLDER’S EQUITY

The Company is authorized to issue up to 5.0 shares of preferred stock, par value $0.01 per share. There were no preferred shares outstanding at June 30, 2015, 2014 and 2013.

The Company is authorized to issue up to 150.0 shares of common stock, par value $0.01 per share. There were 68.9, 73.5 and 80.6 shares issued and outstanding at June 30, 2015, 2014 and 2013 respectively.

Stock Repurchase Program

In March 2015, the Company completed its sixth share repurchase program, which authorized the repurchase of up to $300.0 of the Company’s common stock. In February 2015, the Company’s Board of Directors authorized a seventh share repurchase program of $200.0 of the Company’s outstanding common stock. The Company plans to repurchase its common stock from time to time or on an accelerated basis through open market transactions or privately negotiated transactions as determined by the Company’s management. The amount and timing of stock repurchases under the program will depend on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. As of June 30, 2015, the Company has $155.0 remaining on its current share repurchase authorization.

The Company uses the par value method of accounting for its stock repurchases. As a result of the stock repurchases, the Company reduced common stock and additional paid-in capital and recorded charges to accumulated deficit. The shares retired, aggregate common stock and additional paid-in capital reductions, and related charges to accumulated deficit for the repurchases for periods ended June 30, 2015, 2014 and 2013 were as follows:

	Year ended June 30,
	2015		2014		2013
Shares purchased and retired		6.0		10.4		5.6

Foreign		(12.1	)		(14.2	)		(10.3	)
Total	$	134.9		$	277.8		$	233.3

The differences between income taxes at the statutory federal income tax rate and income taxes reported in the consolidated statements of operations were as follows:

	Year ended June 30,
	2015			2014			2013
Federal income tax expense at the statutory rate		35.0	%		35.0	%		35.0	%

Other, net		0.4			0.5			0.2
Effective income tax rate		40.6	%		36.6	%		36.9	%

The Company’s effective tax rate for the year ended June 30, 2015 was greater than the years ended June 30, 2014 and 2013. This increase was primarily due to an increase in the Company’s liability for unrecognized tax benefits, an increase in the valuation allowance attributable to state research credits and an adjustment in the deferred tax liability related to intangible assets acquired in 2011. The Company evaluated the intangible assets acquired in 2011 as part of the acquisition of Rules Based Medicine and determined that no tax basis is available for the intangible asset for In Process Research & Development. This resulted in an adjustment to the related deferred tax liability and a corresponding increase in the Company’s deferred income tax expense. The effective tax rate was also negatively impacted by foreign losses for which no benefit is recognized. The fiscal 2015 foreign losses, and the resulting impact on the effective rate, were larger in proportion to consolidated income as compared to the earlier years.

63

The significant components of the Company’s deferred tax assets and liabilities were comprised of the following at June 30, 2015 and 2014:

	Year ended June 30,
	2015			2014
Deferred tax assets:
Net operating loss carryforwards	$	61.1		$	77.0
Property, plant and equipment		2.9			2.9
Accrued vacation		1.7			1.6
Allowance for doubtful accounts		2.7			3.3
Stock compensation expense		36.8			26.0
Research and development credits		8.9			11.2
Uncertain state tax positions		1.1			0.6
Other, net		0.9			0.3
Total gross deferred tax assets		116.1			122.9
Less valuation allowance		(33.4	)		(41.4	)
Total deferred tax assets		82.7			81.5
Deferred tax liabilities:
Intangible assets		69.4			71.8
Total deferred tax liabilities		69.4			71.8
Net deferred tax assets		13.3			9.7
Current net deferred tax asset		13.5			6.5
Long term net deferred tax asset		(0.2	)		3.2
Net deferred tax asset	$	13.3		$	9.7

Due to sustained positive operating performance and the availability of expected future taxable income, the Company concluded that it is more likely than not that the benefits of the majority of its deferred income tax assets will be realized. However, for certain deferred tax assets, a valuation allowance has been established. For the years ended June 30, 2015 and 2014, the Company’s valuation allowance decreased by $8.0 and increased by $33.2, respectively. The net decrease of the valuation allowance in the year ended June 30, 2015 consisted of a decrease of $11.5 related to the use of California net operating losses and credits made available through a post-acquisition California stand-alone state tax election and an offsetting increase in the amount of $3.5 which was related to foreign net operating losses and state tax research credits, for which the company concluded it was more likely than not that the benefits of the losses and credits will not be realized. The increase for the year ended June 30, 2014 consisted of $29.7 related to the acquisition of Crescendo Bioscience, Inc. and $3.5 primarily due to foreign net operating losses, for which the Company concluded it was more likely than not that the benefits of the losses will not be realized.

For the years ended June 30, 2015 and 2014, the Company realized $3.4 and $11.1, respectively, of excess tax benefits from stock-based compensation as a reduction of taxes payable. Excess tax benefits from stock based compensation are credited directly to additional paid-in-capital. The Company has adopted the with-and-without tax allocation approach for excess tax benefits, which results in the windfall tax benefits being utilized last after considering all other tax attributes available to the Company.

64

At June 30, 2015, the Company had the following net operating loss and research credit carryforwards, with their respective expiration periods. Certain carryforwards are subject to the limitations of Section 382 and 383 of the Internal Revenue Code as indicated

Carryforwards	Amount		Subject to sections 382, 383	Expires beginning in year	Through
Federal net operating loss	$	138.4	Yes	2027	2033
Utah net operating loss		229.9	No	2016	2024
Oklahoma net operating loss		14.1	Yes	2023	2033
Foreign net operating losses (various jurisdictions)		39.3	No	Various	Various
Federal research credit		3.2	Yes	2025	2032
Utah research credit		8.6	No	2021	2029

Due to a post-acquisition California stand-alone state election related to the acquisition of Crescendo Bioscience, Inc., all of Crescendo’s California net operating loss carryforwards and California research credit carryforwards were utilized or lost at the acquisition, resulting in no remaining carryforwards.

All of the Utah net operating loss carryforwards are ‘excess tax benefits’ as defined by ASC guidance and, if realized in future years, will be recognized as a credit to additional paid-in capital. Approximately $92.6 of the Utah net operating loss ‘excess tax benefits’ are attributable to periods prior to adoption of guidance limiting recognition of the deferred tax asset and are included in deferred tax assets (prior to any offset by valuation allowance.) The remaining $137.3 of Utah net operating loss ‘excess tax benefits’ are not included in deferred tax assets and will be recognized only upon realization of the tax benefit.

The Company’s deferred tax asset for the Utah net operating loss ‘excess tax benefits’ attributable to periods prior to the adoption of the standard is approximately $3.0 and is offset by a full valuation allowance at June 30, 2015. If the ‘excess tax benefits’ are recognized as additional paid-in-capital in future years, the corresponding valuation allowance will be reversed.

Consistent with the indefinite reversal criteria of ASC 740-30-25-17, the Company intends to invest undistributed earnings of its foreign subsidiaries indefinitely. Due to the cumulative losses that have been incurred to date in its foreign operations, the amount of unrecorded deferred liability resulting from the indefinite reversal criteria at June 30, 2015 is $0.

In July 2006, the FASB issued ASC Topic 740 Subtopic 10 Section 05, which clarifies the accounting for uncertainty in tax positions. Accounting guidance requires that the impact of a tax position be recognized in the financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The Company adopted the guidance on July 1, 2007 and recorded $0 cumulative effect. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Year ended June 30,
	2015		2014			2013
Unrecognized tax benefits at the beginning of year	$	24.2	$	10.9		$	10.2
Gross increases - current year tax positions		1.1		1.8			0.7
Gross increases - prior year tax positions		1.0		0.3			—
Gross increases - acquisitions		—		14.2			—
Gross decreases - prior year tax positions		—		(3.0	)		—
Unrecognized tax benefits at end of year	$	26.3	$	24.2		$	10.9
Interest and penalties in year-end balance	$	1.0	$	0.6		$	0.3

Interest and penalties related to uncertain tax positions are included as a component of income tax expense.

The Company files U.S., foreign and state income tax returns in jurisdictions with various statutes of limitations. The years ended June 30, 2012 through June 30, 2015 remain subject to examination at June 30, 2015. The Company’s New

65

Jersey State income tax returns for the years ended June 30, 2007 through 2013 are currently under examination by the New Jersey State Division of Taxation and Finance. Annual tax provisions include amounts considered necessary to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues may differ materially from the amount accrued. The Company’s U.S. federal tax return, foreign income tax returns and all other state tax returns are not currently under examination.

11. SHARE-BASED COMPENSATION

The Company maintains a share-based compensation plan, the 2010 Employee, Director and Consultant Equity Incentive Plan, as amended (the “2010 Plan”), that has been approved by the Company’s shareholders. The 2010 Plan allows the Company, under the direction of the Compensation Committee of the Board of Directors, to make grants of stock options, restricted and unrestricted stock awards and other stock-based awards to employees, consultants and directors. On December 5, 2013, the shareholders approved an amendment to the 2010 Plan to set the number of shares available for grant to 3.5. As of June 30, 2015, a total of 2.2 shares of common stock are available for issuance under the 2010 Plan. In addition, as of June 30, 2015, the Company may grant up to 4.4 additional shares under the 2010 Plan if options previously granted under the Company’s terminated 2003 Employee, Director and Consultant Option Plan are cancelled or expire in the future without the issuance of shares of common stock by the Company. The exercise price of options granted in 2015, 2014 and 2013 was equivalent to the fair market value of the stock at the date of grant. The number of shares, terms, and vesting periods are determined by the Company’s board of directors or a committee thereof on an option-by-option basis. Options generally vest ratably over service periods of four years. Options granted after December 5, 2012 expire eight years from the date of grant, and options granted prior to that date generally expire ten years from the date of grant. In September 2014, the Company began issuing restricted stock units (“RSUs”) in lieu of stock options. RSUs generally vest ratably over four years on the anniversary date of the grant to all employees and directors. The number of RSUs awarded to certain executive officers may be reduced if certain additional performance metrics are not met.

The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants for the fiscal year ended June 30:

	2015			2014			2013
Risk-free interest rate		1.6	%		1.6	%		0.8	%
Expected dividend yield		0	%		0	%		0	%
Expected lives (in years)		4.1 - 4.7			4.1 - 4.7			4.2 - 4.7
Expected volatility		40	%		40	%		44	%

Expected option lives and volatilities are based on historical data of the Company and other factors.

Employee Stock Purchase Plan

The Company had an Employee Stock Purchase Plan that was approved by shareholders in 1995 (the “1995 Purchase Plan”), and subsequently amended, under which 2.0 shares of common stock had been authorized. As of December 5, 2012, a total of 2.0 shares of common stock had been issued under the 1995 Purchase Plan when it was terminated. On December 5, 2012, following shareholder approval, the Company adopted the 2012 Employee Stock Purchase Plan (the “2012 Purchase Plan”), under which 2.0 shares of common stock have been authorized. Shares are issued under the 2012 Purchase Plan twice yearly at the end of each offering period. At June 30, 2015, a total of 0.4 shares of common stock had been purchased under the 2012 Plan. Shares purchased under and compensation expense associated with the 1995 and 2012 Plans for the years reported are as follows:

12. FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial instruments reflects the amounts that the Company estimates to receive in connection with the sale of an asset or paid in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2— observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities.

Level 3—unobservable inputs.

69

The substantial majority of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. The following table sets forth the fair value of the Company’s financial assets that are re-measured on a regular basis:

	Level 1		Level 2		Level 3		Total
at June 30, 2015

Total	$	13.6	$	211.8	$	—	$	225.4

(a) Money market funds are primarily comprised of exchange traded funds and accrued interest

The Company’s Level 1 assets include money market instruments. Level 2 assets consist of marketable investment securities that include federal agency issues, commercial paper, corporate bonds, and municipal bonds. Level 2 securities are valued based upon observable inputs that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications. As of June 30, 2015 and 2014, the Company had no investments which were measured using unobservable (Level 3) inputs.

13. COMMITMENT AND CONTINGENCIES

15. SEGMENT AND RELATED INFORMATION

The Company’s business units have been changed to align with how its Chief Operating Decision Maker (“CODM”) review performance and make decisions in managing the Company. The business units were historically comprised of three reportable segments: (i) research, (ii) molecular diagnostics and (iii) pharmaceutical and clinical services. Currently the business units have been aggregated into two reportable segments: (i) diagnostics and (ii) other, which was formerly the research and pharmaceutical and clinical services segments. The diagnostics segment provides testing and collaborative development of testing that is designed to assess an individual’s risk for developing disease later in life, identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment, or assess a patient’s risk of disease progression and disease recurrence. The other segment provides testing products and

71

services to the pharmaceutical, biotechnology and medical research industries, research and development, and clinical services for patients, and includes corporate services such as finance, human resources, legal and information technology. The prior periods presented have been restated to conform to the current presentation.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies (Note 1). The Company evaluates segment performance based on income (loss) before interest income and other income and expense.

Item 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Not applicable.

Item 9A. CONTROLS AND PROCEDURES

1. Disclosure Controls and Procedures

We maintain disclosure controls and procedures (Disclosure Controls) within the meaning of Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Our Disclosure Controls are designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Our Disclosure Controls are also designed to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our Disclosure Controls,

73

management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily applied its judgment in evaluating and implementing possible controls and procedures.

As of the end of the period covered by this Annual Report on Form 10-K, we evaluated the effectiveness of the design and operation of the Company’s Disclosure Controls, which was done under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer. Based on the evaluation of our Disclosure Controls, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2015, our Disclosure Controls were effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

2. Internal Control Over Financial Reporting

a. Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, a company’s principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Our management assessed the effectiveness of our internal control over financial reporting as of June 30, 2015. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO) in Internal Control—Integrated Framework. Based on our assessment, management believes that, as of June 30, 2015, our internal control over financial reporting is effective based on those criteria.

Management has excluded the Clinic from its assessment of internal control over financial reporting as of June 30, 2014, because we acquired the Clinic in a business combination on February 27, 2015. The Clinic is a wholly-owned subsidiary whose total assets and net assets represent 4.4% and 3.2%, respectively, and revenues and net income represent 0.9% and 0.0%, respectively, for the year ended June 30, 2015.

The effectiveness of Myriad Genetics, Inc.’s internal control over financial reporting as of June 30, 2015, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report as follows:

b. Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Myriad Genetics, Inc.

We have audited Myriad Genetics, Inc. and subsidiaries’ internal control over financial reporting as of June 30, 2015, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Myriad Genetics, Inc. and subsidiaries’ management is

74

responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying Management’s Report on Internal Control over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG, which is included in the fiscal 2015 consolidated financial statements of Myriad Genetics, Inc. and subsidiaries and constituted 4.4% and 3.2% of total and net assets, respectively, as of June 30, 2015 and 0.9% and 0.0% of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of Myriad Genetics, Inc. and subsidiaries also did not include an evaluation of the internal control over financial reporting of Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG.

In our opinion, Myriad Genetics, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of June 30, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Myriad Genetics, Inc. and subsidiaries as of June 30, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended June 30, 2015 of Myriad Genetics, Inc. and subsidiaries and our report dated August 12, 2015 expressed an unqualified opinion thereon.

c. Change in Internal Control over Financial Reporting

Organization and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Jun. 30, 2015

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

Myriad Genetics, Inc. and subsidiaries (collectively, the Company) is a leading molecular diagnostic company focused on developing and marketing novel predictive medicine, personalized medicine and prognostic medicine tests. The Company employs a number of proprietary technologies, including DNA, RNA and protein analysis, that help it to understand the genetic basis of human disease and the role that genes and their related proteins may play in the onset and progression of disease. The Company uses this information to guide the development of new molecular diagnostic and companion diagnostic tests that are designed to assess an individual’s risk for developing disease later in life (predictive medicine), identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment (personalized medicine), or assess a patient’s risk of disease progression and disease recurrence (prognostic medicine). The Company generates revenue by performing molecular diagnostic tests as well as by providing pharmaceutical and clinical services to the pharmaceutical and biotechnology industries and medical research institutions utilizing its multiplexed immunoassay technology. The Company’s corporate headquarters is located in Salt Lake City, Utah.

The consolidated financial statements of the Company are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with U.S. GAAP. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. A reclassification of $0.6 and $0.7 from proceeds from maturities and sales of marketable securities was made to reflect the effect of foreign exchange rates on cash and cash equivalents in the condensed consolidated statement of cash flows and for the fiscal year ended June 30, 2014 and 2013 respectively, and a reclassification of $0.6 from other receivables to trade accounts receivable in the condensed consolidated balance sheet for fiscal year ended June 30, 2014 to conform to the current-year presentation.

Marketable Investment Securities

Marketable Investment Securities

The Company has classified its marketable investment securities as available-for-sale. Available-for-sale investment securities with remaining maturities of greater than one year are classified as long-term. Available-for-sale investment securities with remaining maturities of less than one year are classified as short-term. Available-for-sale investment securities with remaining maturities of less than three months at the time of purchase are classified as cash equivalents. Marketable securities are carried at estimated fair value with unrealized holding gains and losses, net of the related tax effect, included in accumulated other comprehensive (loss) in stockholders’ equity until realized. Gains and losses on investment security transactions are reported using the specific-identification method. Dividend and interest income are recognized when earned.

A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and establishes a new cost basis for the security. Losses are charged against “Other income” when a decline in fair value is determined to be other than temporary. We review several factors to determine whether a loss is other than temporary. These factors include but are not limited to: (i) the extent to which the fair value is less than cost and the cause for the fair value decline, (ii) the financial condition and near term prospects of the issuer, (iii) the length of time a security is in an unrealized loss position and (iv) our ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. There were no other-than-temporary impairments recognized during the fiscal years ended June 30, 2015, 2014 and 2013.

Inventory

Inventory

Inventories consist of reagents, plates and testing kits. Inventories are stated at the lower of cost or market on a first-in, first-out basis. In order to assess the ultimate realization of inventories, the Company is required to make judgments as to future demand requirements compared to current or committed inventory levels.

The Company evaluates its inventories for excess quantities and obsolescence. Inventories that are considered obsolete are expensed. The valuation of inventories requires the use of estimates as to the amounts of current inventories that will be sold. These estimates are dependent on management’s assessment of current and expected orders from the Company’s customers.

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are comprised of amounts due from sales of the Company’s molecular diagnostic tests and pharmaceutical and clinical services and are recorded at the invoiced amount, net of discounts and contractual allowances. The allowance for doubtful accounts is based on the Company’s best estimate of the amount of probable losses in the Company’s existing accounts receivable, which is based on historical write-off experience, customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers and does not require collateral.

Property, Plant and Equipment

Property, Plant and Equipment

Equipment and leasehold improvements are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method based on the lesser of estimated useful lives of the related assets or lease terms. Equipment items have depreciable lives of five to seven years. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the associated lease terms, which range from three to fifteen years. Repairs and maintenance costs are charged to expense as incurred.

Intangible Assets and Other Long-Lived Assets

Intangible Assets and Other Long-Lived Assets

Intangible and other long-lived assets are comprised of acquired licenses and intellectual property and purchased in-process research and development. Acquired intangible assets are recorded at fair value and amortized over the shorter of the contractual life or the estimated useful life. The estimated useful life of acquired in-process research and development was also evaluated in conjunction with the annual impairment analysis of intangible assets. The classification of the acquired in-process research and development as an indefinite lived asset was deemed appropriate as the related research and development was not yet complete nor had it been abandoned.

The Company continually reviews and monitors long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Goodwill

Goodwill

Goodwill is tested for impairment on an annual basis as of April 1 and in the interim by reporting unit if events and circumstances indicate that goodwill may be impaired. The events and circumstances that are considered include business climate and market conditions, legal factors, operating performance indicators and competition. Impairment of goodwill was evaluated using a two-step process. The first step involves a comparison of the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the fair value and the carrying amount of the goodwill of that reporting unit. If the carrying amount of the goodwill of the reporting unit exceeds the fair value of that goodwill, an impairment loss would be recognized in an amount equal to the excess of carrying value over fair value. If an event occurs that would cause a revision to the estimates and assumptions used in analyzing the value of the goodwill, the revision could result in a non-cash impairment charge that could have a material impact on the financial results.

Revenue Recognition

Revenue Recognition

Molecular diagnostic testing revenue is recognized when persuasive evidence of an agreement exists, results have been communicated to the patient, the fee is fixed or determinable, and collection is reasonably assured. Revenue from the sale of molecular diagnostic tests and related marketing agreements is recorded at the invoiced amount net of any discounts or contractual allowances.

Pharmaceutical and clinical service revenue is recognized when persuasive evidence of an agreement exists, the fee is fixed and or determinable, when the service has been completed and the results of the tests/service are provided to the customer, and collectability is reasonably assured. In addition, the Company’s wholly owned subsidiary, Myriad RBM, has received national, state, foreign government and private foundation grants and contracts. Revenue associated with these grants and contracts is recognized in the period in which qualifying costs for the services by the grants and contracts are incurred and the related grant or contract fee is earned.

Income Taxes

Income Taxes

The Company recognizes income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities.

The provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and any estimated valuation allowances deemed necessary to recognize deferred tax assets at an amount that is more likely than not to be realized. The Company’s filings, including the positions taken therein, are subject to audit by various taxing authorities. While the Company believes it has provided adequately for its income tax liabilities in the consolidated financial statements, adverse determinations by these taxing authorities could have a material adverse effect on the consolidated financial condition, results of operations or cash flows.

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share is computed based on the weighted-average number of shares of common stock, including the dilutive effect of common stock equivalents, outstanding.

The following is a reconciliation of the denominators of the basic and diluted earnings per share computations:

	Years Ended June 30,
	2015		2014		2013
Denominator:
Weighted-average shares outstanding used to compute basic EPS		71.3		75.7		80.9
Effect of dilutive stock options		3.2		2.5		2.4
Weighted-average shares outstanding and dilutive securities used to compute diluted EPS		74.5		78.2		83.3

Certain outstanding options and RSUs were excluded from the computation of diluted earnings per share because the effect would have been anti-dilutive. These potential dilutive common shares, which may be dilutive to future diluted earnings per share, are as follows:

	Years Ended June 30,
	2015		2014		2013
Anti-dilutive options and RSUs excluded from EPS computation		—		—		—

Foreign Currency

Foreign Currency

The functional currency of the Company’s international subsidiaries is the local currency. For those subsidiaries, expenses denominated in the functional currency are translated into U.S. dollars using average exchange rates in effect during the period and assets and liabilities are translated using period-end exchange rates. The foreign currency translation adjustments are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ (deficit) equity.

The following table shows the cumulative translation adjustments included in other comprehensive income, net of tax:

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires Company management to make estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount of fixed assets, valuation allowances for receivables and deferred income tax assets, certain accrued liabilities, share-based compensation and impairment analysis of goodwill and intangible assets. Actual results could differ from those estimates.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May, 2015, the Financial Accounting Standards Board issued ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and which should be applied retrospectively to all periods presented. Earlier application is permitted. The new amendment removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient. In addition, the amendments remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers.” Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. It is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. We are currently evaluating the impact, if any, the adoption of this standard will have on our consolidated financial statements.

Business Acquisitions

2. BUSINESS ACQUISITIONS

German Clinic

On February 27, 2015, the Company completed the acquisition of privately-held Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG (the “Clinic”) approximately 15 miles from the Company’s European laboratories in Munich, Germany. The cash paid and preliminary total consideration transferred to acquire the Clinic was $20.1.

Total consideration transferred was allocated to tangible assets acquired and liabilities assumed based on their preliminary fair values at the acquisition date as set forth below. The Company believes acquisition of the Clinic may facilitate the Company’s penetration into the German molecular diagnostic market. The Clinic will allow the Company to directly negotiate reimbursement with government and private insurance providers for our tests in the German market and collaborate with hospitals and physician groups. These factors contributed to consideration transferred in excess of the fair value of the Clinic’s net tangible and intangible assets acquired, resulting in the Company recording goodwill in connection with the transaction. Under German tax law the goodwill related to the purchase of the clinic is deductible and will be amortized for tax purposes over 15 years.

Management estimated the fair value of tangible and intangible assets and liabilities in accordance with the applicable accounting guidance for business combinations and utilized the services of third-party valuation consultants. The preliminary allocation of the consideration transferred is subject to potential adjustments primarily due to tax-related matters, including tax basis of acquired assets and liabilities in the foreign jurisdiction, and third party valuations of acquired assets and liabilities, including actuarial analysis of pension assets and liabilities and fair value of equipment. During the measurement period, the Company may record adjustments to the provisional amounts recognized in the Company’s initial accounting for the acquisition. The Company expects the allocation of the consideration transferred to be final within the measurement period (up to one year from the acquisition date).

	Estimated Fair Value
Current assets	$	3.1
Real property		20.7
Equipment		1.6
Goodwill		8.1
Current liabilities		(4.4	)
Long-term liabilities		(9.0	)
Total purchase price	$	20.1

During the current period there were adjustments to long-term liabilities, deferred grants and goodwill. The long-term liabilities increased by approximately $2.0 due to information obtained from the third party actuary analysis of the pension obligation which increased goodwill for further information on the pension see Note 8. The deferred grants fair value was determined to be $0.0 by management. This fair value adjustment decreased the deferred grants to $0.0 and decreased goodwill by $10.7.

Crescendo Bioscience, Inc.

On February 28, 2014, the Company completed the acquisition of privately-held Crescendo Bioscience, Inc. (“Crescendo”), pursuant to an Amended and Restated Agreement and Plan of Merger, dated February 2, 2014 (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, Myriad acquired Crescendo for total consideration of $259.0 as detailed below, by means of a reverse triangular merger in which Crescendo survived the merger as the surviving corporation and a wholly-owned subsidiary of Myriad. The surviving corporation operates under the name Crescendo Bioscience, Inc.

The following table reconciles consideration transferred to the total cash paid to acquire Crescendo:

Total consideration transferred	$	259.0
Share-based compensation to Crescendo employees		6.9
Change of control payments to Crescendo employees		5.7
Offset: Non-cash fair value purchase option		(8.0	)
Total cash paid	$	263.6

The total consideration of $259.0 consisted of (i) $225.1 in cash, (ii) $25.9 in elimination of intercompany balances related to accrued interest and the term loan the Company issued to Crescendo on September 8, 2011, and (iii) $8.0 related to the fair value of the purchase option granted to the Company on September 8, 2011 by Crescendo through a definitive merger agreement (“Option Agreement”) entered into in association with the term note. Of the cash consideration, $20.0 was deposited into an escrow account to fund (i) any post-closing adjustments payable to Myriad based upon differences between the estimated working capital and the actual working capital of Crescendo at closing, and (ii) any indemnification claims made by Myriad against Crescendo, for a period of time, based upon the completion of an audit of Crescendo’s financial statements, of no fewer than twelve nor more than fifteen months following closing.

Of the total cash paid, $6.9 was accounted for as share-based compensation expense resulting from the accelerated vesting of employee options immediately prior to the acquisition and $5.7 was accounted for as change of control bonuses paid to Crescendo employees and directors. The Company recognized the share-based compensation expense and change of control bonuses in post-acquisition Consolidated Statements of Comprehensive Income for the year ended June 30, 2014.

Total consideration transferred was allocated to tangible and identifiable intangible assets acquired and liabilities assumed based on their preliminary fair values at the acquisition date as set forth below. The Company believes that the acquisition of Crescendo facilitates the Company’s entry into the high growth autoimmune market, diversifies its product revenue and enhances its strength in protein-based diagnostics. These factors contributed to consideration transferred in excess of the fair value of Crescendo’s net tangible and intangible assets acquired, resulting in the Company recording goodwill in connection with the transaction.

The Company’s allocation of consideration transferred for Crescendo is as follows:

	Estimated Fair Value
Other assets acquired	$	15.9
Intangible assets		196.6
Goodwill		112.3
Total assets acquired		324.8
Deferred tax liabilities		44.2
Other liabilities assumed		21.6
Total net assets acquired	$	259.0

Pro Forma Information

The unaudited pro-forma results presented below include the effects of the Crescendo acquisition as if it had been consummated as of July 1, 2013, with adjustments to give effect to pro forma events that are directly attributable to the acquisition which includes adjustments related to the amortization of acquired intangible assets, interest income and expense, stock-based compensation expense, and depreciation. The unaudited pro forma results do not reflect any operating efficiency or potential cost savings which may result from the consolidation of Crescendo. Accordingly, these unaudited pro forma results are presented for informational purposes only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of the period presented nor are they indicative of future results of operations and are not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been consummated as of July 1, 2013.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Financial Statement Presentation

Myriad Genetics, Inc. and subsidiaries (collectively, the Company) is a leading molecular diagnostic company focused on developing and marketing novel predictive medicine, personalized medicine and prognostic medicine tests. The Company employs a number of proprietary technologies, including DNA, RNA and protein analysis, that help it to understand the genetic basis of human disease and the role that genes and their related proteins may play in the onset and progression of disease. The Company uses this information to guide the development of new molecular diagnostic and companion diagnostic tests that are designed to assess an individual’s risk for developing disease later in life (predictive medicine), identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment (personalized medicine), or assess a patient’s risk of disease progression and disease recurrence (prognostic medicine). The Company generates revenue by performing molecular diagnostic tests as well as by providing pharmaceutical and clinical services to the pharmaceutical and biotechnology industries and medical research institutions utilizing its multiplexed immunoassay technology. The Company’s corporate headquarters is located in Salt Lake City, Utah.

The consolidated financial statements of the Company are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the accompanying financial statements contain all adjustments (consisting of normal and recurring accruals) necessary to present fairly all financial statements in accordance with U.S. GAAP. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. A reclassification of $0.6 and $0.7 from proceeds from maturities and sales of marketable securities was made to reflect the effect of foreign exchange rates on cash and cash equivalents in the condensed consolidated statement of cash flows and for the fiscal year ended June 30, 2014 and 2013 respectively, and a reclassification of $0.6 from other receivables to trade accounts receivable in the condensed consolidated balance sheet for fiscal year ended June 30, 2014 to conform to the current-year presentation.

Marketable Investment Securities

The Company has classified its marketable investment securities as available-for-sale. Available-for-sale investment securities with remaining maturities of greater than one year are classified as long-term. Available-for-sale investment securities with remaining maturities of less than one year are classified as short-term. Available-for-sale investment securities with remaining maturities of less than three months at the time of purchase are classified as cash equivalents. Marketable securities are carried at estimated fair value with unrealized holding gains and losses, net of the related tax effect, included in accumulated other comprehensive (loss) in stockholders’ equity until realized. Gains and losses on investment security transactions are reported using the specific-identification method. Dividend and interest income are recognized when earned.

A decline in the market value of any available-for-sale security below cost that is deemed other than temporary results in a charge to earnings and establishes a new cost basis for the security. Losses are charged against “Other income” when a decline in fair value is determined to be other than temporary. We review several factors to determine whether a loss is other than temporary. These factors include but are not limited to: (i) the extent to which the fair value is less than cost and the cause for the fair value decline, (ii) the financial condition and near term prospects of the issuer, (iii) the length of time a security is in an unrealized loss position and (iv) our ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. There were no other-than-temporary impairments recognized during the fiscal years ended June 30, 2015, 2014 and 2013.

Inventory

Inventories consist of reagents, plates and testing kits. Inventories are stated at the lower of cost or market on a first-in, first-out basis. In order to assess the ultimate realization of inventories, the Company is required to make judgments as to future demand requirements compared to current or committed inventory levels.

The Company evaluates its inventories for excess quantities and obsolescence. Inventories that are considered obsolete are expensed. The valuation of inventories requires the use of estimates as to the amounts of current inventories that will be sold. These estimates are dependent on management’s assessment of current and expected orders from the Company’s customers.

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are comprised of amounts due from sales of the Company’s molecular diagnostic tests and pharmaceutical and clinical services and are recorded at the invoiced amount, net of discounts and contractual allowances. The allowance for doubtful accounts is based on the Company’s best estimate of the amount of probable losses in the Company’s existing accounts receivable, which is based on historical write-off experience, customer creditworthiness, facts and circumstances specific to outstanding balances, and payment terms. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers and does not require collateral.

Property, Plant and Equipment

Equipment and leasehold improvements are stated at cost less accumulated depreciation. Depreciation and amortization are computed using the straight-line method based on the lesser of estimated useful lives of the related assets or lease terms. Equipment items have depreciable lives of five to seven years. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the associated lease terms, which range from three to fifteen years. Repairs and maintenance costs are charged to expense as incurred.

Intangible Assets and Other Long-Lived Assets

Intangible and other long-lived assets are comprised of acquired licenses and intellectual property and purchased in-process research and development. Acquired intangible assets are recorded at fair value and amortized over the shorter of the contractual life or the estimated useful life. The estimated useful life of acquired in-process research and development was also evaluated in conjunction with the annual impairment analysis of intangible assets. The classification of the acquired in-process research and development as an indefinite lived asset was deemed appropriate as the related research and development was not yet complete nor had it been abandoned.

The Company continually reviews and monitors long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Goodwill

Goodwill is tested for impairment on an annual basis as of April 1 and in the interim by reporting unit if events and circumstances indicate that goodwill may be impaired. The events and circumstances that are considered include business climate and market conditions, legal factors, operating performance indicators and competition. Impairment of goodwill was evaluated using a two-step process. The first step involves a comparison of the fair value of the reporting unit with its carrying amount. If the carrying amount of the reporting unit exceeds its fair value, the second step of the process involves a comparison of the fair value and the carrying amount of the goodwill of that reporting unit. If the carrying amount of the goodwill of the reporting unit exceeds the fair value of that goodwill, an impairment loss would be recognized in an amount equal to the excess of carrying value over fair value. If an event occurs that would cause a revision to the estimates and assumptions used in analyzing the value of the goodwill, the revision could result in a non-cash impairment charge that could have a material impact on the financial results.

Revenue Recognition

Molecular diagnostic testing revenue is recognized when persuasive evidence of an agreement exists, results have been communicated to the patient, the fee is fixed or determinable, and collection is reasonably assured. Revenue from the sale of molecular diagnostic tests and related marketing agreements is recorded at the invoiced amount net of any discounts or contractual allowances.

Pharmaceutical and clinical service revenue is recognized when persuasive evidence of an agreement exists, the fee is fixed and or determinable, when the service has been completed and the results of the tests/service are provided to the customer, and collectability is reasonably assured. In addition, the Company’s wholly owned subsidiary, Myriad RBM, has received national, state, foreign government and private foundation grants and contracts. Revenue associated with these grants and contracts is recognized in the period in which qualifying costs for the services by the grants and contracts are incurred and the related grant or contract fee is earned.

Income Taxes

The Company recognizes income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities.

The provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and any estimated valuation allowances deemed necessary to recognize deferred tax assets at an amount that is more likely than not to be realized. The Company’s filings, including the positions taken therein, are subject to audit by various taxing authorities. While the Company believes it has provided adequately for its income tax liabilities in the consolidated financial statements, adverse determinations by these taxing authorities could have a material adverse effect on the consolidated financial condition, results of operations or cash flows.

Earnings Per Share

Basic earnings per share is computed based on the weighted-average number of shares of common stock outstanding. Diluted earnings per share is computed based on the weighted-average number of shares of common stock, including the dilutive effect of common stock equivalents, outstanding.

The following is a reconciliation of the denominators of the basic and diluted earnings per share computations:

	Years Ended June 30,
	2015		2014		2013
Denominator:
Weighted-average shares outstanding used to compute basic EPS		71.3		75.7		80.9
Effect of dilutive stock options		3.2		2.5		2.4
Weighted-average shares outstanding and dilutive securities used to compute diluted EPS		74.5		78.2		83.3

Certain outstanding options and RSUs were excluded from the computation of diluted earnings per share because the effect would have been anti-dilutive. These potential dilutive common shares, which may be dilutive to future diluted earnings per share, are as follows:

	Years Ended June 30,
	2015		2014		2013
Anti-dilutive options and RSUs excluded from EPS computation		—		—		—

Foreign Currency

The functional currency of the Company’s international subsidiaries is the local currency. For those subsidiaries, expenses denominated in the functional currency are translated into U.S. dollars using average exchange rates in effect during the period and assets and liabilities are translated using period-end exchange rates. The foreign currency translation adjustments are included in accumulated other comprehensive income (loss) as a separate component of stockholders’ (deficit) equity.

The following table shows the cumulative translation adjustments included in other comprehensive income, net of tax:

Balance at June 30, 2014	$	(1.8	)
Period translation adjustments		(5.2	)
Ending balance June 30, 2015		(7.0	)

Use of Estimates

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires Company management to make estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount of fixed assets, valuation allowances for receivables and deferred income tax assets, certain accrued liabilities, share-based compensation and impairment analysis of goodwill and intangible assets. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In May, 2015, the Financial Accounting Standards Board issued ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years and which should be applied retrospectively to all periods presented. Earlier application is permitted. The new amendment removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value (“NAV”) per share practical expedient. In addition, the amendments remove the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued ASU No. 2014-09, “Revenue from Contracts with Customers.” Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. It is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. We are currently evaluating the impact, if any, the adoption of this standard will have on our consolidated financial statements.

Segment and Related Information

15. SEGMENT AND RELATED INFORMATION

The Company’s business units have been changed to align with how its Chief Operating Decision Maker (“CODM”) review performance and make decisions in managing the Company. The business units were historically comprised of three reportable segments: (i) research, (ii) molecular diagnostics and (iii) pharmaceutical and clinical services. Currently the business units have been aggregated into two reportable segments: (i) diagnostics and (ii) other, which was formerly the research and pharmaceutical and clinical services segments. The diagnostics segment provides testing and collaborative development of testing that is designed to assess an individual’s risk for developing disease later in life, identify a patient’s likelihood of responding to drug therapy and guide a patient’s dosing to ensure optimal treatment, or assess a patient’s risk of disease progression and disease recurrence. The other segment provides testing products and services to the pharmaceutical, biotechnology and medical research industries, research and development, and clinical services for patients, and includes corporate services such as finance, human resources, legal and information technology.

The Company’s effective tax rate for the year ended June 30, 2015 was greater than the years ended June 30, 2014 and 2013. This increase was primarily due to an increase in the Company’s liability for unrecognized tax benefits, an increase in the valuation allowance attributable to state research credits and an adjustment in the deferred tax liability related to intangible assets acquired in 2011. The Company evaluated the intangible assets acquired in 2011 as part of the acquisition of Rules Based Medicine and determined that no tax basis is available for the intangible asset for In Process Research & Development. This resulted in an adjustment to the related deferred tax liability and a corresponding increase in the Company’s deferred income tax expense. The effective tax rate was also negatively impacted by foreign losses for which no benefit is recognized. The fiscal 2015 foreign losses, and the resulting impact on the effective rate, were larger in proportion to consolidated income as compared to the earlier years.

The significant components of the Company’s deferred tax assets and liabilities were comprised of the following at June 30, 2015 and 2014:

	Year ended June 30,
	2015			2014
Deferred tax assets:
Net operating loss carryforwards	$	61.1		$	77.0
Property, plant and equipment		2.9			2.9
Accrued vacation		1.7			1.6
Allowance for doubtful accounts		2.7			3.3
Stock compensation expense		36.8			26.0
Research and development credits		8.9			11.2
Uncertain state tax positions		1.1			0.6
Other, net		0.9			0.3
Total gross deferred tax assets		116.1			122.9
Less valuation allowance		(33.4	)		(41.4	)
Total deferred tax assets		82.7			81.5
Deferred tax liabilities:
Intangible assets		69.4			71.8
Total deferred tax liabilities		69.4			71.8
Net deferred tax assets		13.3			9.7
Current net deferred tax asset		13.5			6.5
Long term net deferred tax asset		(0.2	)		3.2
Net deferred tax asset	$	13.3		$	9.7

Due to sustained positive operating performance and the availability of expected future taxable income, the Company concluded that it is more likely than not that the benefits of the majority of its deferred income tax assets will be realized. However, for certain deferred tax assets, a valuation allowance has been established. For the years ended June 30, 2015 and 2014, the Company’s valuation allowance decreased by $8.0 and increased by $33.2, respectively. The net decrease of the valuation allowance in the year ended June 30, 2015 consisted of a decrease of $11.5 related to the use of California net operating losses and credits made available through a post-acquisition California stand-alone state tax election and an offsetting increase in the amount of $3.5 which was related to foreign net operating losses and state tax research credits, for which the company concluded it was more likely than not that the benefits of the losses and credits will not be realized. The increase for the year ended June 30, 2014 consisted of $29.7 related to the acquisition of Crescendo Bioscience, Inc. and $3.5 primarily due to foreign net operating losses, for which the Company concluded it was more likely than not that the benefits of the losses will not be realized.

For the years ended June 30, 2015 and 2014, the Company realized $3.4 and $11.1, respectively, of excess tax benefits from stock-based compensation as a reduction of taxes payable. Excess tax benefits from stock based compensation are credited directly to additional paid-in-capital. The Company has adopted the with-and-without tax allocation approach for excess tax benefits, which results in the windfall tax benefits being utilized last after considering all other tax attributes available to the Company.

At June 30, 2015, the Company had the following net operating loss and research credit carryforwards, with their respective expiration periods. Certain carryforwards are subject to the limitations of Section 382 and 383 of the Internal Revenue Code as indicated

Carryforwards	Amount		Subject to sections 382, 383	Expires beginning in year	Through
Federal net operating loss	$	138.4	Yes	2027	2033
Utah net operating loss		229.9	No	2016	2024
Oklahoma net operating loss		14.1	Yes	2023	2033
Foreign net operating losses (various jurisdictions)		39.3	No	Various	Various
Federal research credit		3.2	Yes	2025	2032
Utah research credit		8.6	No	2021	2029

Due to a post-acquisition California stand-alone state election related to the acquisition of Crescendo Bioscience, Inc., all of Crescendo’s California net operating loss carryforwards and California research credit carryforwards were utilized or lost at the acquisition, resulting in no remaining carryforwards.

All of the Utah net operating loss carryforwards are ‘excess tax benefits’ as defined by ASC guidance and, if realized in future years, will be recognized as a credit to additional paid-in capital. Approximately $92.6 of the Utah net operating loss ‘excess tax benefits’ are attributable to periods prior to adoption of guidance limiting recognition of the deferred tax asset and are included in deferred tax assets (prior to any offset by valuation allowance.) The remaining $137.3 of Utah net operating loss ‘excess tax benefits’ are not included in deferred tax assets and will be recognized only upon realization of the tax benefit.

The Company’s deferred tax asset for the Utah net operating loss ‘excess tax benefits’ attributable to periods prior to the adoption of the standard is approximately $3.0 and is offset by a full valuation allowance at June 30, 2015. If the ‘excess tax benefits’ are recognized as additional paid-in-capital in future years, the corresponding valuation allowance will be reversed.

Consistent with the indefinite reversal criteria of ASC 740-30-25-17, the Company intends to invest undistributed earnings of its foreign subsidiaries indefinitely. Due to the cumulative losses that have been incurred to date in its foreign operations, the amount of unrecorded deferred liability resulting from the indefinite reversal criteria at June 30, 2015 is $0.

In July 2006, the FASB issued ASC Topic 740 Subtopic 10 Section 05, which clarifies the accounting for uncertainty in tax positions. Accounting guidance requires that the impact of a tax position be recognized in the financial statements if that position is more likely than not of being sustained on audit, based on the technical merits of the position. The Company adopted the guidance on July 1, 2007 and recorded $0 cumulative effect. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Year ended June 30,
	2015		2014			2013
Unrecognized tax benefits at the beginning of year	$	24.2	$	10.9		$	10.2
Gross increases - current year tax positions		1.1		1.8			0.7
Gross increases - prior year tax positions		1.0		0.3			—
Gross increases - acquisitions		—		14.2			—
Gross decreases - prior year tax positions		—		(3.0	)		—
Unrecognized tax benefits at end of year	$	26.3	$	24.2		$	10.9
Interest and penalties in year-end balance	$	1.0	$	0.6		$	0.3

Interest and penalties related to uncertain tax positions are included as a component of income tax expense.

The Company files U.S., foreign and state income tax returns in jurisdictions with various statutes of limitations. The years ended June 30, 2012 through June 30, 2015 remain subject to examination at June 30, 2015. The Company’s New Jersey State income tax returns for the years ended June 30, 2007 through 2013 are currently under examination by the New Jersey State Division of Taxation and Finance. Annual tax provisions include amounts considered necessary to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues may differ materially from the amount accrued. The Company’s U.S. federal tax return, foreign income tax returns and all other state tax returns are not currently under examination.

Share-Based Compensation

11. SHARE-BASED COMPENSATION

The Company maintains a share-based compensation plan, the 2010 Employee, Director and Consultant Equity Incentive Plan, as amended (the “2010 Plan”), that has been approved by the Company’s shareholders. The 2010 Plan allows the Company, under the direction of the Compensation Committee of the Board of Directors, to make grants of stock options, restricted and unrestricted stock awards and other stock-based awards to employees, consultants and directors. On December 5, 2013, the shareholders approved an amendment to the 2010 Plan to set the number of shares available for grant to 3.5. As of June 30, 2015, a total of 2.2 shares of common stock are available for issuance under the 2010 Plan. In addition, as of June 30, 2015, the Company may grant up to 4.4 additional shares under the 2010 Plan if options previously granted under the Company’s terminated 2003 Employee, Director and Consultant Option Plan are cancelled or expire in the future without the issuance of shares of common stock by the Company. The exercise price of options granted in 2015, 2014 and 2013 was equivalent to the fair market value of the stock at the date of grant. The number of shares, terms, and vesting periods are determined by the Company’s board of directors or a committee thereof on an option-by-option basis. Options generally vest ratably over service periods of four years. Options granted after December 5, 2012 expire eight years from the date of grant, and options granted prior to that date generally expire ten years from the date of grant. In September 2014, the Company began issuing restricted stock units (“RSUs”) in lieu of stock options. RSUs generally vest ratably over four years on the anniversary date of the grant to all employees and directors. The number of RSUs awarded to certain executive officers may be reduced if certain additional performance metrics are not met.

The fair value of each option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants for the fiscal year ended June 30:

	2015			2014			2013
Risk-free interest rate		1.6	%		1.6	%		0.8	%
Expected dividend yield		0	%		0	%		0	%
Expected lives (in years)		4.1 - 4.7			4.1 - 4.7			4.2 - 4.7
Expected volatility		40	%		40	%		44	%

Expected option lives and volatilities are based on historical data of the Company and other factors.

Goodwill and Intangible Assets

5. GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company has recorded goodwill of $177.2 from the acquisitions of Privatklinik Dr. Robert Schindlbeck GmbH & Co. KG that was completed on February 27, 2015, Crescendo Bioscience, Inc. that was completed on February 28, 2014 and Rules-Based Medicine, Inc. that was completed on May 31, 2011. Of this goodwill, $112.3 relates to the Company’s diagnostic segment and $64.9 related to the other segment. The Company assessed goodwill for impairment in accordance with the appropriate guidance (see Note 1) and recorded no impairment of goodwill for the period ended June 30, 2015. Included in the other segment is $8.0 in goodwill associated with the acquisition of the Clinic which is preliminary and subject to adjustment within the measurement period (see Note 2). The following summarizes changes to the goodwill balance for the years ended June 30, 2015 and 2014:

	Years Ended June 30,

Ending balance	$	177.2		$	169.2

Intangible Assets

Intangible assets primarily consist of amortizable assets of purchased licenses and technologies, developed technology, a laboratory database, trademarks, and customer relationships as well as non-amortizable intangible assets of in-process technologies, research and development. Certain of these intangible assets were recorded as part of the Company’s purchase of Crescendo on February 28, 2014 and Myriad RBM on May 31, 2011. The Company’s developed technology and database acquired have estimated remaining useful lives of 16 years, trademarks acquired in have an estimated remaining useful life of approximately 13 years and customer relationships have an estimated remaining useful life of approximately 6 years. The estimated useful life of acquired in-process research and development was also evaluated in conjunction with the annual impairment analysis of intangible assets. The classification of the acquired in-process research and development as an indefinite lived asset was deemed appropriate as the related research and development was not yet complete nor had it been abandoned. In December 2012, the Company notified the licensor of the Company’s OnDose product of the Company’s intent to terminate the license agreement, and as a result, recorded an impairment charge of approximately $1.5 associated with the purchased license agreement. Other than this $1.5 impairment charge, the Company concluded there was no impairment of long-lived assets for the years ended June 30, 2015, 2014 and 2013.

The following summarizes the amounts reported as intangible assets:

	Gross Carrying Amount		Accumulated Amortization			Net

Total intangible assets	$	213.6	$	(8.3	)	$	205.3

As of June 30, 2015 the weighted average remaining amortization period for purchased licenses and technologies, trademarks, and customer relationships is approximately 15 years.

The Company recorded amortization during the respective periods for these intangible assets as follows:

	Years Ended June 30,

Fair Value Measurements

12. FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial instruments reflects the amounts that the Company estimates to receive in connection with the sale of an asset or paid in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1—quoted prices in active markets for identical assets and liabilities.

Level 2— observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Some of the Company’s marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities.

Level 3—unobservable inputs.

The substantial majority of the Company’s financial instruments are valued using quoted prices in active markets or based on other observable inputs. The following table sets forth the fair value of the Company’s financial assets that are re-measured on a regular basis:

	Level 1		Level 2		Level 3		Total
at June 30, 2015
Money market funds (a)	$	2.4	$	—	$	—	$	2.4

Total	$	13.6	$	211.8	$	—	$	225.4

(a) Money market funds are primarily comprised of exchange traded funds and accrued interest

The Company’s Level 1 assets include money market instruments. Level 2 assets consist of marketable investment securities that include federal agency issues, commercial paper, corporate bonds, and municipal bonds. Level 2 securities are valued based upon observable inputs that may include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications. As of June 30, 2015 and 2014, the Company had no investments which were measured using unobservable (Level 3) inputs.

Cost Basis Investment

6. COST BASIS INVESTMENT

In April 2013, the Company acquired approximately 28 shares of Series E preferred stock of RainDance Technologies, Inc. (“RainDance”) of Lexington, Massachusetts, for $5.0. RainDance provides high-throughput picodroplet-based technology that can encapsulate a single molecule, cell or reaction and be digitally analyzed and sorted one at a time. The Series E shares purchased by the Company represented less than 5% of the total shares outstanding of RainDance’s capital stock. Subsequent to the investment the Company evaluated its relationship with RainDance and determined it did not have significant influence over the operations of RainDance. The Company’s investment in RainDance has been recorded under the cost method as an “Other Asset” on the Company’s consolidated balance sheet. The Company periodically evaluates the investment for impairment. No impairment indicators were noted at June 30, 2015.

Stock Repurchase Program

In March 2015, the Company completed its sixth share repurchase program, which authorized the repurchase of up to $300.0 of the Company’s common stock. In February 2015, the Company’s Board of Directors authorized a seventh share repurchase program of $200.0 of the Company’s outstanding common stock. The Company plans to repurchase its common stock from time to time or on an accelerated basis through open market transactions or privately negotiated transactions as determined by the Company’s management. The amount and timing of stock repurchases under the program will depend on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. As of June 30, 2015, the Company has $155.0 remaining on its current share repurchase authorization.

The Company uses the par value method of accounting for its stock repurchases. As a result of the stock repurchases, the Company reduced common stock and additional paid-in capital and recorded charges to accumulated deficit. The shares retired, aggregate common stock and additional paid-in capital reductions, and related charges to accumulated deficit for the repurchases for periods ended June 30, 2015, 2014 and 2013 were as follows:
