Important Information Forward-Looking Statements This presentation contains forward-looking statements that may discuss Aravive’s plans, goals, intentions and expectations as to future trends, events, results of operations, financial condition or other matters. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and they often include words such as “may,” “will,” “should,” “would,” “expect,” “anticipate,” “plan,” “likely,” “believe,” “estimate,” “project,” “intend,” and other similar expressions. Statements that are not historical facts are forward-looking statements. Forward-looking statements included in this presentation include statements regarding Aravive’s planned clinical activities, including the design, initiation, patient enrollment and availability of data from clinical studies, future indications and cash position and the anticipated safety, activity and manufacturability of Aravive’s product candidates. Forward-looking statements are based on Aravive’s current beliefs and assumptions, are subject to risks and uncertainties and are not guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various factors, including, without limitation: the unpredictability of clinical development activities; risks related to Aravive’s ability to estimate and control its operating expenses; Aravive’s ability to protect its intellectual property rights; changes in the competitive environment; and legislative, regulatory, political and economic developments. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including the risk factors included in Aravive’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and Current Reports on Form 8-K filed with the Securities and Exchange Commission. Except as required by law, Aravive undertakes no obligation to revise or update any forward-looking statement or to make any other forward-looking statements, whether as a result of new information, future events or otherwise.
