Cautionary Note Regarding Forward-Looking Statements

This Annual Report on Form 10-K contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, that reflect our current expectations about our future results, performance, prospects and opportunities. These forward-looking statements are not guarantees of future performance and are subject to significant risks, uncertainties, assumptions and other factors, which are difficult to predict and may cause actual results to differ materially from those expressed in, or implied by, any forward-looking statements. The forward-looking statements within this report may be identified by words such as “believes,” “anticipates,” “expects,” “intends,” “may,” “would,” “will” and other similar expressions. However, these words are not the exclusive means of identifying these statements. Statements that are not historical facts are based on our current expectations, beliefs, assumptions, estimates, forecasts and projections for our business and the industry and markets related to our business and are forward-looking statements.

Actual outcomes and results may differ materially from what is expressed in such forward-looking statements. Important factors which may affect these actual outcomes and results include, without limitation:

●uncertainty as to whether our product candidates will be sufficiently safe and effective to support regulatory approvals;
●uncertainty inherent in developing therapeutics and vaccines, and manufacturing and conducting preclinical and clinical trials;
●our ability to obtain future financing or funds when needed, either through the raising of capital, the incurrence of convertible or other indebtedness or through strategic financing or commercialization partnerships;
●our ability to secure government grants or contracts to support our vaccine development;
●our ability to maintain our listing on Nasdaq and meet Nasdaq’s listing requirements;
●that product development and commercialization efforts will be reduced or discontinued due to difficulties or delays in clinical trials or a lack of progress or positive results from research and development efforts;
●maintenance and progression of our business strategy;
●the possibility that our products under development may not gain market acceptance;
●our expectations about the potential market sizes and market participation potential for our product candidates may not be realized;
●our expected revenues (including sales, milestone payments and royalty revenues) from our product candidates and any related commercial agreements of ours may not be realized;
●the ability of our manufacturing partners to supply us or our commercial partners with clinical or commercial supplies of our products in a safe, timely and regulatory compliant manner and the ability of such partners to timely address any regulatory issues that have arisen or may arise in the future;
●competition existing today or that may arise in the future, including the possibility that others may develop technologies or products superior to our products;
●the effect that global pathogens could have on financial markets, materials sourcing, service providers, patients, clinical study sites, governments and population (e.g. Coronavirus Disease 2019 (“COVID-19”)); and
●other factors, including those “Risk Factors” set forth under Part I, Item 1A. “Risk Factors” in this Annual Report.

Except as expressly required by the federal securities laws, we undertake no obligation to publicly update or revise any forward-looking statements to reflect events or circumstances occurring subsequent to the filing of this Form 10-K with the

United States (“U.S.”) Securities and Exchange Commission (“the SEC”) or for any other reason.
