Vaxart Announces First Quarter 2019 Financial Results and Provides Corporate Update

Vaxart, Inc., a clinical-stage biotechnology company developing oral recombinant vaccines that are administered by tablet rather than by injection, today announced financial results for the first quarter ended March 31, 2019.

“With the Phase 1b study of our bivalent norovirus tablet vaccine underway and two successful financings behind us, we are well positioned to advance our lead product candidate, the first oral vaccine against norovirus, the leading cause of food-borne illness in the U.S.,” said Wouter Latour, M.D., chief executive officer of Vaxart. “We expect to initiate the Phase 2 monovalent norovirus challenge study in the first half of 2019, and we expect topline results from both the Phase 1b and Phase 2 studies in the second half of 2019. In addition, we are advancing our first therapeutic vaccine for the treatment of HPV associated cervical dysplasia and cancer toward the clinic.”

2019 Highlights:

Corporate:

• On March 8, Vaxart announced the initiation of the open label lead-in portion of its Phase 1b bivalent norovirus vaccine clinical trial. On March 27, the Company announced it had completed dosing of the lead-in cohort, and on April 16 the first patient in the randomized cohort of the clinical trial was dosed.
• On March 19, Vaxart announced the pricing of a registered direct offering of 1,200,000 shares of its common stock at a price of $2.50 per share. Total gross proceeds from the offering were $3.0 million.
• On April 1, at the International Society for Influenza and other Respiratory Virus Diseases conference in Siena, Italy, and on April 3, at the Influenza Vaccines for the World 2019 conference in Edinburgh, Scotland, Vaxart presented new data from its Phase 2 influenza challenge study further solidifying the evidence that its oral tablet vaccine protects against influenza infection, primarily through mucosal immunity.
• On April 9, Vaxart announced the pricing of an underwritten public offering of a total of 925,455 shares of common stock and 8,165,455 pre-funded warrants with an exercise price of $0.10 per share, as well as common warrants for 10,454,546 shares with an exercise price of $1.10 per share. The gross proceeds of the offering at close were $9.3 million. As of May 8, 2019, 6,519,091 pre-funded warrants had been exercised, bringing the aggregate gross proceeds up to $10.0 million, and 1,646,364 pre-funded warrants remained outstanding.
• On April 13, at the 29th European Congress of Clinical Microbiology and Infectious Diseases in Amsterdam, the Netherlands, Vaxart presented preclinical data showing that Vaxart’s oral quadrivalent seasonal influenza vaccine conferred 100% protection against a lethal H5N1 pre-pandemic influenza challenge in ferrets, while in the Fluzone group only 62% of the animals survived.

Financial Results for the Three Months Ended March 31, 2019

• Vaxart reported a net loss of $1.3 million for the first quarter of 2019 compared to net income of $2.3 million for the first quarter of 2018. The principal reason for the decrease was the absence of a $7.0 million one-off non-cash bargain purchase gain recorded in the first quarter of 2018, partially offset by an increase in revenue of $3.9 million, primarily from royalties on Inavir and Relenza.
• Vaxart ended the quarter with cash and cash equivalents of $8.4 million compared to $11.5 million at December 31, 2018. The decrease was primarily due to cash used in operations, partially offset by the $2.5 million net raised in the registered direct offering in March 2019.
• Revenue for the quarter was $5.4 million compared to $1.5 million in the first quarter of 2018. The $3.9 million increase was principally due to royalty revenue resulting from our merger with Aviragen being recorded for the full quarter in 2019, while in 2018 the majority of this revenue was earned pre-merger.
• Research and development expenses were $3.8 million for the quarter compared to $3.4 million for the first quarter of 2018. The increase was mainly due to higher clinical and manufacturing costs incurred in the Company’s norovirus program and amortization of intangible assets acquired in the merger with Aviragen, partially offset by the discontinuation of the teslexivir program and completion of the BARDA contract.
• General and administrative expenses were $2.0 million for the quarter, substantially unchanged from the first quarter of 2018.
