The video segment may also contain forward-looking statements. Any forward-looking statements set forth in this press release speak only as of the date hereof and any forward-looking statements in the video segment speak only as of the date thereof. Such forward-looking statements may include statements relating to: the timing of commencement, enrollment, completion, and results of clinical trials; IP expansion and regulatory progress; and timing for receiving government approvals, if at all. For all forward-looking statements, the Company claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. All statements in this press release and the video segment other than statements of historical fact, including statements regarding the potential of Ampligen’s mechanism of action, anticipated regulatory milestones, our future results of operations and financial position, our business strategy and plans, and our objectives for future operations, are forward-looking statements. For both this press release and the video segment, words such as “believe,” “may,” “might,” “will,” “could,” “should,” “can,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “envision” and similar expressions are intended to identify forward looking statements, but the absence of these words does not mean that a statement is not forward-looking. All discussions regarding Ampligen’s therapeutic potential in pancreatic cancer reflect the presenters’ views are based on data from the previously announced, completed Named Patient Program/Early Access Program and on interim reports regarding an ongoing Phase 2 clinical trial involving co-administration of Ampligen with another drug. As such, they are interpretations of the significance of available data and analyses and projections by the presenters regarding the potential that a Phase 3 trial would produce positive results in support of a New Drug Application. See a more detailed analysis of the EAP and the Phase 2 clinical trial in AIM’s corporate presentation: https://aimimmuno.com/presentations/. The Company does not undertake to update any of these forward-looking statements to reflect events or circumstances that occur after the date hereof, except as required by applicable law. The Company is in various stages of seeking to determine whether Ampligen will be effective in the treatment of multiple types of viral diseases, cancers, and immune-deficiency disorders, and disclosures in the Company’s reports filed with the SEC, on its website, and in its press releases set forth its current and anticipated future activities. These activities are subject to change for a number of reasons. Significant additional testing and trials will be required to determine whether Ampligen® will be effective in the treatment of these conditions. Results obtained in preclinical studies do not necessarily predict results in humans. Human clinical trials will be necessary to prove whether or not Ampligen® will be efficacious in humans. No assurance can be given as to whether current or planned clinical trials will be successful or yield favorable data, and the trials are subject to many factors including lack of regulatory approval(s), lack of study drug, lack of adequate funding, or a change in priorities at the institutions sponsoring other trials. Even if these clinical trials are initiated, the Company cannot assure that the clinical studies will be successful or yield any useful data. No assurance can be given that the findings in preliminary studies will prove true or that such studies will yield favorable results, or that future studies will not result in findings that are different from those reported in the studies referenced in the Company’s reports filed with the SEC, on the Company’s website, and in its press releases. Operating in foreign countries carries with it a number of risks, including potential difficulties in enforcing intellectual property rights. The Company cannot assure that its potential foreign operations will not be adversely affected by these risks.

For a detailed discussion of risk factors, please review the “Risk Factors” section in the Company’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q filed with the SEC. These filings are available at www.sec.gov and www.aimimmuno.com.
