CAMBRIDGE, Mass. (November 8, 2021) – VBI Vaccines Inc. (Nasdaq: VBIV) (VBI), a biopharmaceutical company driven by immunology in the pursuit of powerful prevention and treatment of disease, today reported financial results for the third quarter ending September 30, 2021 and provided a corporate update.

Jeff Baxter, VBI’s President and CEO commented: “The third quarter of 2021 was a notably busy and productive time as we support the ongoing regulatory reviews of our prophylactic 3-antigen HBV vaccine candidate, prepare for the potential launch of this candidate in the U.S., Europe, and Canada, and advance both our immunotherapeutic vaccine candidates against GBM and chronic HBV, as well as our coronavirus pipeline, with the objective of creating vaccines that provide long-term breadth of protection with good safety and tolerability profiles. We look forward to sharing data and updates from the various milestones expected over the next six months across our portfolio. The public health space is constantly evolving, evidenced by the renewed focus on prevention of HBV with the recently revised adult vaccination guidelines, plus the mutational evolution of COVID-19 with new and emerging variants. We are working hard to address significant and relevant unmet medical and public health needs, we believe this dedication and focus on successfully achieving these fundamentals will drive shareholder value.”

COVID-19 & Coronaviruses

VBI-2900 : eVLP Coronavirus Vaccine Program

● September 2021 : Initiation of Phase 1b study of VBI-2905, VBI’s eVLP vaccine candidate targeting the Beta variant, as both a single-dose booster in adults previously vaccinated with a full course of messenger RNA (mRNA) vaccine, and as a two-dose regimen in unvaccinated adults

● Q1 2022 : Initial data expected from one-dose booster study arm, in previously vaccinated adults, in ongoing Phase 1b study

● Mid-year 2022 : Expected initiation of the first clinical study of VBI’s trivalent pan-coronavirus vaccine candidate, VBI-2901, designed to increase the breadth of immunity against emerging COVID-19 variants and betacoronviruses

Glioblastoma (GBM)

VBI-1901: Cancer Vaccine Immunotherapeutic Candidate

● Based on data seen to-date, we anticipate assessing VBI-1901 in randomized, controlled clinical studies in both primary and recurrent GBM patients as part of the next phase of development

● Q1 2022 : Expected initiation of enrollment of expanded number of patients in ongoing study in recurrent GBM, subject to discussions with FDA, increasing study size and adding a control arm to support the potential for accelerated approval based on tumor response data and improvement in overall survival

● Mid-year 2022 : Expected initiation of a randomized, controlled clinical study with registration potential in primary GBM patients, subject to discussions with FDA

Third Quarter 2021 Financial Results

● Cash Position: VBI ended the third quarter of 2021 with $137.5 million in cash, cash equivalents, and short-term investments compared with $93.8 million as of December 31, 2020.

● Net Cash Used in Operating Activities: Net cash used in operating activities for the nine months ended September 30, 2021 was $21.4 million, compared to $30.6 million for the same period in 2020. The decrease in cash outflows is largely a result of the change in operating working capital, notably the cash received in advance from the CEPI funding agreement, offset by an increase in net loss.

● Cash Used for Purchase of Property and Equipment: Cash used for the purchase of property and equipment was $1.4 million for the nine months ended September 30, 2021, compared to $0.5 million for the same period in 2020. The increase is a result of routine purchases of property and equipment at our manufacturing facility in Rehovot, Israel.

● Revenue: Revenue in the third quarter of 2021 was $0.1 million, compared to $0.3 million for the same period in 2020. The decrease in revenues was due to a decrease in R&D services revenue as part of the collaboration with Brii Bio. Fewer manufacturing and non-clinical research services were done in the three months ending September 30, 2021 compared to the three months ending September 30, 2020.

● Cost of Revenues: Cost of revenues was $2.5 million in the third quarter of 2021 as compared to $2.1 million for the same period in 2020. The increase in the cost of revenues was due to increased outsourced testing costs and inventory-related costs incurred in the three months ending September 30, 2021 compared to the same period in 2020.

● Research and Development (R&D): R&D expenses for the third quarter of 2021 were $3.0 million compared to $4.5 million in the third quarter of 2020. The decrease was a result of the government grants and funding arrangements, offset by an increase in the costs related to our coronavirus vaccine program, including the Phase 1a and Phase 1b portions of VBI-2902 and VBI-2905, respectively, and development and manufacturing of VBI-2905. The increase was also due to an increase in R&D expenses related to the development of our other vaccine candidates.

● General and Administrative (G&A): G&A expenses were $9.7 million for the third quarter of 2021, compared to $5.6 million for the same period in 2020. The increase was a result of the increased commercialization preparation activities related to the 3-antigen prophylactic HBV vaccine candidate in anticipation of potential regulatory approvals, in addition to increased insurance and labor costs.

● Net Loss: Net Loss and net loss per share for the third quarter of 2021 were $15.8 million and $0.06, respectively, compared to a net loss of $13.0 million and a net loss per share of $0.06 for the third quarter of 2020.
