NASDAQ: ABUS www.arbutusbio.com Forward - Looking Statements 2 This presentation contains forward - looking statements within the meaning of the U . S . Private Securities Litigation Reform Act of 1995 and Canadian securities laws . All statements that are not historical facts are hereby identified as forward - looking statements for this purpose and include, among others, statements relating to : the potential market opportunity for HBV ; Arbutus’ ability to meet a significant unmet medical need ; the sufficiency of Arbutus’ cash and cash equivalents for the anticipated durations ; the expected cost, timing and results of Arbutus’ clinical development plans and clinical trials, including its clinical collaborations with third parties ; the potential for Arbutus’ product candidates to achieve their desired or anticipated outcomes ; Arbutus’ expectations regarding the timing and clinical development of Arbutus’ product candidates, including its articulated clinical objectives ; the timeline to a combination cure for HBV ; Arbutus’ coronavirus strategy ; Arbutus’ expectations regarding its technology licensed to third parties ; the expected timing and payments associated with strategic and/or licensing agreements ; the patent infringement lawsuit against Moderna ; and other statements relating to Arbutus’ future operations, future financial performance, future financial condition, prospects or other future events . With respect to the forward - looking statements contained in this presentation, Arbutus has made numerous assumptions regarding, among other things : the timely receipt of expected payments ; the effectiveness and timeliness of preclinical studies and clinical trials, and the usefulness of the data ; the timeliness of regulatory approvals ; the continued demand for Arbutus’ assets ; and the stability of economic and market conditions . While Arbutus considers these assumptions to be reasonable, these assumptions are inherently subject to significant business, economic, competitive, market and social uncertainties and contingencies including uncertainties and contingencies related to the ongoing COVID - 19 pandemic and patent litigation matters . Forward - looking statements herein involve known and unknown risks, uncertainties and other factors that may cause the actual results, events or developments to be materially different from any future results, events or developments expressed or implied by such forward - looking statements . Such factors include, among others : anticipated pre - clinical and clinical trials may be more costly or take longer to complete than anticipated, and may never be initiated or completed, or may not generate results that warrant future development of the tested drug candidate ; changes in Arbutus’ strategy regarding its product candidates and clinical development activities ; Arbutus may not receive the necessary regulatory approvals for the clinical development of Arbutus' products ; economic and market conditions may worsen ; uncertainties associated with litigation generally and patent litigation specifically ; market shifts may require a change in strategic focus ; the parties may never realize the expected benefits of the collaborations ; and the ongoing COVID - 19 pandemic could significantly disrupt Arbutus’ clinical development programs .
