Nexvet Reports Financial Results for First Quarter of Fiscal Year 2016

DUBLIN, Ireland – November 5, 2015 – Veterinary biologic therapy developer Nexvet Biopharma (Nasdaq: NVET) today announced its financial results for the three month period ended September 30, 2015.

Corporate Highlights

• Commenced a research and development collaboration with leading Japanese animal health company, Zenoaq (Nippon Zenyaku Kogyo Co., Ltd.)

• Secured a dedicated biologics manufacturing facility in Tullamore, Ireland

• Received $3.1 million cash under the Australian Government’s Research and Development (R&D) Tax Incentive program

In July 2015, Nexvet announced the commencement of a research and development collaboration with Zenoaq (Nippon Zenyaku Kogyo Co., Ltd.), a leading animal health company based in Japan. The collaboration entails developing a number of therapeutic biologics in the areas of immuno-oncology and allergy/inflammation. Nexvet is applying its PETization platform technology to convert monoclonal antibodies (mAbs) identified by Zenoaq into 100% species-specific product candidates for conditions where there is currently a significant unmet medical need. Nexvet will retain marketing rights outside Europe and Asia to any resulting approved products.

A key highlight during the quarter was the securing of a dedicated biologics manufacturing facility in Tullamore, Ireland. In September 2015, Nexvet agreed to pay $1.98 million to secure the manufacturing assets within the 20,000 square foot facility. The Company entered into a 10-year lease on the facility and has the option to purchase the building. As part of the transaction, Nexvet is eligible for non-dilutive grant support from the Irish Government. This acquisition affirms Nexvet’s commitment to internalize manufacturing, a key element in the development and commercialization of innovative biopharmaceuticals.

Nexvet continues to maintain important research and development operations in Australia and in September 2015 announced receipt of $3.1 million in cash under the Australian Government’s Research and Development (R&D) Tax Incentive program. The incentive was included as a receivable in Nexvet’s annual report on Form 10-K, for the fiscal year ended June 30, 2015.

Recent Developments

In October 2015, Nexvet announced the initiation of a pilot field study of NV-02, its mAb therapy in development for the control of pain associated with osteoarthritis in cats. The study will target enrolment of 90 feline patients with naturally occurring osteoarthritis. Nexvet expects data from the study will be available in the second quarter of 2016. Nexvet believes this is the most advanced clinical study of a feline mAb therapy. Chronic pain management is an area of significant unmet need in cats, given that non-steroidal anti-inflammatory drugs (NSAIDs), a leading class of analgesics for dogs and cats, are not approved for chronic use in cats in the United States due to concerns over toxic side effects.

First Quarter FY2016 Financial Results

As of September 30, 2015, Nexvet had cash of $47.7 million.

For the three months ended September 30, 2015, Nexvet reported a net loss of $4.0 million, compared to $2.3 million for the three months ended September 30, 2014. Net loss per share attributable to ordinary shareholders (basic and diluted) for the three months ended September 30, 2015 and 2014 was $0.35 and $2.13 respectively.

The net loss of $4.0 million for the three months ended September 30, 2015 included operating expenses of $5.6 million, reflecting $3.7 million in research and development expenses and $1.9 million in general and administrative expenses. Other income comprised $1.6 million, principally research and development incentive income of $0.6 million and an exchange gain of $1.0 million.

The net loss of $2.3 million for the three months ended September 30, 2014 included operating expenses of $5.4 million, reflecting $2.5 million in research and development expenses and $2.8 million in general and administrative expenses. Other income comprised $3.0 million, principally research and development incentive income of $0.7 million, government grant income of $0.3 million and an exchange gain of $2.0 million.

The increased operating expenses for the three month period ended September 30, 2015, compared to the corresponding period in 2014, primarily related to increased program development costs associated with the pivotal safety and efficacy study for NV-01 and proof-of-concept studies for NV-02, offset by a $1.0 million reduction in general and administrative costs due to costs associated with preparation for our initial public offering of $0.6 million and Irish reorganization costs of $0.4 million in the three months ended September 30, 2014.
