Financial Results for the Three Months Ended March 2024

	●	Cash Position: As of March 31, 2024 VBI had $12.6 million in cash as compared with $23.7 million in cash as of December 31, 2023. Cash position at March 31, 2024, does not include approximately $2.8 million gross proceeds from registered direct offering of common shares and warrants, warrant exercises, and sale of common shares through VBI’s at-the-market facility with Jefferies LLC, subsequent to March 31, 2024 and through early April 2024.
	●	Revenues, net: Revenues, net for the first quarter 2024 were $1.2 million as compared to $0.5 million for the same period in 2023. The revenue increase was a result of an increase in product sales of PreHevbrio in the U.S.
	●	Cost of Revenues: Cost of revenues was $2.7 million in the first quarter of 2024 as compared to $3.6 million in the first quarter of 2023. The decrease in the cost of revenues was a result of the April 2023 organizational changes and decreased inventory-related costs, offset by increased product sales.
	●	Research and Development (R&D): R&D expenses for the first quarter of 2024 were $2.6 million as compared to $3.2 million for the same period in 2023. R&D expenses were offset by $0.7 million for the three months ended March 31, 2024, and $2.4 million for the three months ended March 31, 2023 due to government grants and funding arrangements. The decrease in R&D expenses is primarily a result of decreased development expenses for VBI’s pan-coronavirus and GBM candidates, VBI-2901 and VBI-1901, due to timing of ongoing clinical studies of each candidate.
	●	Sales, General, and Administrative (SG&A): SG&A expenses for the first quarter of 2024 were $7.7 million as compared to $13.3 million in the first quarter of 2023. The decrease in SG&A expenses was mainly a result of the April 2023 organizational changes that reduced our internal workforce, commercial field teams, and operating expenses.
	●	Net Cash Used in Operating Activities: Net cash used in operating activities for the first quarter of 2024 was $11.8 million compared to $21.7 million for the same period in 2023. The 46% decrease in cash outflows is largely due to a decrease in net loss as a result of the April 2023 organizational changes, in addition to the change in operating working capital, most notably in inventory, other current assets, accounts payable, and other current liabilities.
	●	Net Loss and Net Loss Per Share: Net loss and net loss per share for the first quarter of 2024 were $17.9 million and $0.73, respectively, as compared to a net loss and net loss per share of $27.8 million and $3.22 for the first quarter of 2023, respectively.
	●	Net Loss and Net Loss Per Share, Excluding Foreign Exchange Loss: Net loss and net loss per share, excluding foreign exchange loss, for the first quarter 2024 were $13.6 million and $0.55, respectively, compared to $20.9 million and $2.43 for the first quarter 2023, respectively. See “Use of Non-GAAP Financial Measures” 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.

○

Foreign exchange loss for the first quarter of 2024 was $4.3 million as compared to $6.8 million for the first quarter of 2023. Certain intercompany loans between the Company and its subsidiaries are denominated in a currency other than the functional currency of each entity. The decrease in foreign exchange loss was a result of the changes in the foreign currency exchange rates (of the New Israeli Shekel and the Canadian Dollar) in which the foreign currency transactions were denominated for each of those periods, including the foreign exchange impact of intercompany loans that are translated at period end.

Use of Non-GAAP Financial Measures

Net Loss, Excluding Foreign Exchange Loss, and Net Loss Per Share, Excluding Foreign Exchange Loss, are non-GAAP financial measures and are defined as Net Loss and Net Loss Per Share excluding the foreign exchange loss in both calculations. Net Loss, Excluding Foreign Exchange Loss, and Net Loss Per Share, Excluding Foreign Exchange Loss, are 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 Net Loss Per Share, Excluding Foreign Exchange Loss, 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 is a non-recurring item, 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 Foreign Exchange Loss, and Net Loss Per Share to 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.
