South San Francisco, Calif. — August 13, 2014 — Veracyte, Inc. (Nasdaq: VCYT) today reported financial results for the second quarter ended June 30, 2014, and provided an update on business progress. For the second quarter of 2014, revenue was $8.7 million, an increase of 71%, compared to $5.1 million for the second quarter of 2013. Revenue for the six months ended June 30, 2014 was $16.2 million, compared to $9.5 million for the same period in 2013, also an increase of 71%.

“We continued to experience robust momentum with our business during the second quarter of 2014,” said Bonnie H. Anderson, Veracyte’s president and chief executive officer. “We are also especially pleased with our strong achievements at the mid-year mark across the core initiatives that form the foundation of our continued growth and future success. These initiatives include the Afirma Gene Expression Classifier’s inclusion in leading guidelines, positive coverage decisions, the launch of our second Afirma product in endocrinology and advancement of our pulmonary pipeline.”

The company also announced an agreement to amend terms of its co-promotion agreement with Genzyme Corporation, a Sanofi company, designed to retain the benefits of the co-promotion of two leading industry brands and access to a strong endocrinology sales team, while providing greater financial flexibility to Veracyte. Subject to signing the final amendment, effective January 1, 2015, Veracyte’s co-promotion fees paid to Genzyme will decrease from 32% of Afirma revenue to 15% of Afirma revenue in the United States. Both companies will continue to participate in joint marketing activities, with Veracyte assuming greater responsibility for new-account sales conversion and Genzyme’s sales team focusing on ongoing support of new and existing accounts. The companies also agreed to amend the agreement to optimize their joint presence internationally with a country-by-country decision to co-promote or to revert exclusivity back to Veracyte.

“We are pleased we have reached agreement to amend the terms of the co-promotion agreement, which we believe will help position Veracyte for long-term profitability and growth. At this point in the Afirma adoption curve, we believe the shift in sales responsibility is particularly critical to continued successful penetration into more complex institutional accounts and integrated health networks, where a dedicated team approach is required,” said Ms. Anderson. “We look forward to our relationship evolving and are committed to its continued success for both companies.”

Second Quarter 2014 Financial Results

·                                          Revenue for the second quarter of 2014 was $8.7 million, compared to revenue of $5.1 million for the comparable period in 2013, an increase of 71%.

·                                          The company received 16,458 fine needle aspiration (FNA) samples during the second quarter of 2014, compared to 12,424 FNA samples during the same period in 2013, an increase of 32%.

·                                          The rate of GEC tests performed continued to be slightly above 22% of FNA samples received during the quarter, reflecting the company’s strong progress with large institutional accounts, which handle initial cytopathology on-site and only submit indeterminate samples for genomic testing.

·                                          Operating expenses for the second quarter of 2014 were $15.2 million, compared to $10.5 million for the same period in 2013.

·                                          Net loss for the second quarter of 2014 was $6.7 million, or $0.31 per common share, compared with a net loss of $6.5 million, or $7.53 per common share, for the comparable period in 2013.

·                                          Cash and cash equivalents as of June 30, 2014 totaled $58.0 million.

Recent Business Highlights

·                                          Uniquely met, with our Afirma GEC, the proposed inclusion criteria of preliminary American Thyroid Association guidelines for a molecular test to help patients avoid unnecessary surgery following an indeterminate thyroid nodule FNA biopsy result.

·                                          Reached more than 135 million covered lives for the Afirma GEC, including new positive coverage decisions from three Blue Cross Blue Shield-affiliated plans.

·                                          Gained a positive coverage decision from our first managed-Medicaid plan — AmeriHealth Caritas — an increasingly important avenue of reimbursement for the Afirma GEC.

·                                          Launched our Afirma Malignancy Classifiers — comprised of tests for medullary thyroid cancer and to assess BRAF mutational status — and secured New York State regulatory approval, making our comprehensive Afirma solution available to patients nationwide.

·                                          Presented strong preliminary data at the American Thoracic Society’s 2014 international conference in May for a molecular classifier to improve early, non-surgical diagnosis of idiopathic pulmonary fibrosis.

2014 Financial Outlook

The company reiterates its 2014 revenue guidance of $38 million to $43 million. The forecast for the number of FNAs is being revised to a range of 66,000 to 73,000 samples from a range of 76,000 to 83,000 samples. The GEC test rate is expected to come in at the top of the guided range of 20% to 22%, with the number of GEC-only tests higher than expected due to growing adoption by large institutional accounts.

About Veracyte

Veracyte (Nasdaq: VCYT) is pioneering the field of molecular cytology, focusing on genomic solutions that resolve diagnostic ambiguity and enable physicians to make more informed treatment decisions at an early stage in patient care. By improving preoperative diagnostic accuracy, the company aims to help patients avoid unnecessary invasive procedures while reducing healthcare costs. Veracyte’s first commercial solution, the Afirma® Thyroid FNA Analysis, provides a comprehensive approach for assessing thyroid nodules, centered on the proprietary Gene Expression Classifier (GEC) to resolve ambiguity in diagnosis. Each year, of the more than 525,000 thyroid nodule FNAs performed in the U.S., approximately 115,000 patients undergo diagnostic thyroid surgery, with 70% to 80% of nodules proving benign and thus the surgery unnecessary. Veracyte commercially launched Afirma in January 2011. As of June 30, 2014, the company has received nearly 115,000 FNA samples for evaluation using Afirma and has performed over 20,000 GECs to resolve indeterminate cytopathology results. Backed by multiple, peer-reviewed, published studies and included in leading medical guidelines, Afirma is covered by Medicare and major commercial payers, which collectively represent more than 135 million covered lives. Afirma is marketed and sold through a global co-promotion agreement with Genzyme Corporation, a subsidiary of Sanofi. Veracyte intends to expand its molecular cytology franchise to other clinical areas and is in product development for its first product in pulmonology.
