Issuer Free Writing Prospectus, Cautionary Statement Concerning Forward-looking Statements CAUTIONARY STATEMENT CONCERNING FORWARD LOOKING STATEMENTS This document contains forward-looking statements. In addition, from time to time, we or our representatives may make forward-looking statements orally or in writing. We base these forward-looking statements on our expectations and projections about future events, which we derive from the information currently available to us. Such forward-looking statements relate to future events or our future performance, including: our financial performance and projections; our growth in revenue and earnings; and our business prospects and opportunities. You can identify forward-looking statements by those that are not historical in nature, particularly those that use terminology such as "may," "should," "expects," "anticipates," "contemplates," "estimates," "believes," "plans," "projected," "predicts," "potential," or "hopes" or the negative of these or similar terms. In evaluating these forward-looking statements, you should consider various factors, including: our ability to obtain additional funding to develop our product candidates; our ability to satisfy any requirements imposed by the FDA (or its foreign equivalents); the impact of COVID-19 on our clinical trials, preclinical activities and our ability to raise future financing; our ability to continue our relationship with Toray; the need to obtain and retain regulatory approval of our products, both in the United States and in countries deemed necessary for future trials; our ability to complete our clinical trials in a timely fashion and within our expected budget and resources; compliance with obligations under intellectual property licenses with third parties; our ability to commercialize our product candidates; market acceptance of our products; and our dependency on third-party manufacturers to successfully, and timely, supply or manufacture our products. These and other factors may cause our actual results to differ materially from any forward-looking statement. Forward-looking statements are only predictions. The forward-looking events discussed in this document and other statements made from time to time by us or our representatives, may not occur, and actual events and results may differ materially and are subject to risks, uncertainties and assumptions about us. We are not obligated to publicly update or revise any forward-looking statement, whether as a result of uncertainties and assumptions, the forward-looking events discussed in this document and other statements made from time to time by us or our representatives might not occur. bluejay Copyright ©2021 Blunjay Diagnostics, Inc.
