• PreHevbrio (Hepatitis B Vaccine [Recombinant]) global net revenue increased 48% quarter-over-quarter from Q1 to Q2 2023 - redefined, highly targeted commercial field team deployed at the end of Q2
• Expanded hepatitis B collaboration with Brii Biosciences announced in July for $15 million upfront, including a $3 million equity investment, and up to $422 million in potential additional milestones plus double-digit royalties
• Additional $20.5 million gross proceeds from underwritten public offering added to balance sheet in July

VBI Vaccines Inc. (Nasdaq: VBIV) (VBI), a biopharmaceutical company driven by immunology in the pursuit of powerful prevention and treatment of disease, today provided a business update and announced financial results for the quarter ended June 30, 2023.

“Q2 was a period of transition for VBI as we worked to more efficiently align resource deployment and headcount with the opportunities for value creation,” said Jeff Baxter, VBI’s President and CEO. “With, (i) the expansion of our hepatitis B partnership with Brii Biosciences, (ii) our internal workforce reduction largely complete, (iii) the redefined, highly targeted U.S. commercial field force now trained and deployed, and (iv) the additional cash we brought in from our expanded partnership with Brii and our concurrent public offering, we believe we are well-positioned going into the second half of 2023 to execute on our corporate strategy and drive growth and value for key stakeholders – patients, healthcare providers, and shareholders.”

Second Quarter 2023 Financial Results

• Cash Position: VBI ended the second quarter of 2023 with $20.8 million in cash as compared with $62.6 million in cash as of December 31, 2022. Cash position at June 30, 2023 does not include $15 million upfront payment, including $3 million equity investment, from the expanded Brii Bio partnership or $20.5 million gross proceeds from the underwritten public offering, both of which occurred in July 2023.
• Revenues, net: Revenues, net for the second quarter of 2023 were $0.7 million as compared to $0.3 million for the same period in 2022. The revenue increase of 108% was a result of an increase in product sales of PreHevbrio in the U.S., in addition to initial European product sales of PreHevbri to our partner, Valneva.
• Cost of Revenues: Cost of revenues was $3.5 million in the second quarter of 2023 as compared to $2.5 million in the second quarter of 2022. The increase in the cost of revenues was due to increased product sales, direct labor costs, and inventory related costs for the Company’s 3-antigen HBV vaccine.
• Research and Development (R&D): R&D expenses for the second quarter of 2023 were $3.3 million as compared to $5.6 million for the second quarter of 2022. R&D expenses were offset by $2.3 million in the second quarter of 2023 and $1.0 million in the second quarter of 2022 from government grants and funding arrangements.
• Sales, General, and Administrative (SG&A): SG&A expenses for the second quarter of 2023 were $10.9 million as compared to $15.1 million for the same period in 2022. The decrease in SG&A expenses, partially offset by government grants and funding arrangements, was mainly a result of recent organizational changes that reduced our internal workforce, as announced in April 2023, and the redefined deployment strategy of our U.S. commercial field force and activities related to PreHevbrio.
• Net Cash Used in Operating Activities: Net cash used in operating activities for the six months ended June 30, 2023 was $40.9 million compared to $37.4 million for the same period in 2022. The increase in cash outflows is largely a result of an increase in net loss, offset by non-cash reconciling items, mainly impairment charges and unrealized foreign exchange loss and the change in operating working capital, most notably in other current assets, accounts payable and other current liabilities. As announced on April 4, 2023, VBI continues to implement cost saving measures that are expected to reduce operating expenses from normal business in the second half of 2023 by 30-35% compared to the second half of 2022.
• Net Loss and Net Loss Per Share: Net loss and net loss per share for the second quarter of 2023 were $44.6 million and $5.18, respectively, compared to a net loss and net loss per share of $45.7 million and $5.31 for the second quarter of 2022, respectively.
• Net Loss and Net Loss Per Share, Excluding Impairment Charges and Foreign Exchange Loss: Net loss and net loss per share, excluding the non-cash impairment and foreign exchange loss, for the second quarter of 2023 were $18.7 million and $2.17, respectively, compared to $23.8 million and $2.77 for the second quarter of 2022, respectively. See “Non-GAAP Financial Information” below for additional information regarding this non-GAAP financial measure, and “GAAP to Non-GAAP Reconciliation” for a reconciliation of this non-GAAP financial measure to net loss and net loss per share.
  • Impairment for the second quarter of 2023 was $20.0 million as compared to $0 for the second quarter of 2022.
  • Foreign exchange loss for the second quarter of 2023 was $5.9 million as compared to $21.9 million for the second quarter of 2022. Certain intercompany loans between the Company and its subsidiaries are denominated in a currency other than the functional currency of each entity. The primary driver of the increase in foreign exchange loss was the impact of the relative strengthening of the U.S. and Canadian Dollars against the New Israeli Shekel upon translation of these intercompany loans.

Use of Non-GAAP Financial Measures

Net Loss Excluding Foreign Exchange Loss and Impairment Charges and Net Loss per Share Excluding Foreign Exchange Loss and Impairment Charges are non-GAAP financial measures and are defined as net loss excluding foreign exchange loss and impairment charges. Net Loss and Net Loss Per Share, Excluding Impairment and Foreign Exchange Loss is not intended to replace net loss or net loss per share or other measures of financial performance reported in accordance with generally accepted accounting principles (GAAP). VBI’s management believes that the presentation of Net Loss Excluding Foreign Exchange Loss and Impairment Charges and Net Loss per Share Excluding Foreign Exchange Loss and Impairment Charges are useful to investors because management does not consider foreign exchange loss, which is primarily driven by changes in exchange rates related to certain intercompany loans, and impairment charges, which are non-recurring items, when evaluating VBI’s operating performance. Non-GAAP financial measures are meant to supplement, and to be viewed in conjunction with, GAAP financial results. The presentation of these non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s financial statements prepared in accordance with GAAP. Reconciliations of the Company’s non-GAAP measures are included below.

The following represents a reconciliation of Net Loss to Net Loss Excluding Impairment Charges and Foreign Exchange Loss and Net Loss per Share Excluding Foreign Exchange Loss. See “Non-GAAP Financial Information” below for additional information regarding this non-GAAP financial measure, and “GAAP to Non-GAAP Reconciliation” for a reconciliation of this non-GAAP financial measure to net loss and net loss per share.
