Investors are cautioned that such statements, including, without limitation, those regarding the expected 14-month review period for Geron&#x2019;s imetelstat MAA, constitute forward-looking statements. These forward-looking statements involve risks and uncertainties that can cause actual results to differ materially from those in such forward-looking statements. These risks and uncertainties, include, without limitation, risks and uncertainties related to: uncertainty of regulatory actions, approvals or clearances, including the risks that the review period for the MAA may be extended and that the EMA may ultimately determine not to approve the MAA in its present form or at all; the future development of imetelstat, including any future efficacy or safety results that may cause the benefit risk profile of imetelstat to become unacceptable; Geron&#x2019;s need for additional capital to support the development and commercialization of imetelstat and to otherwise grow Geron&#x2019;s business; establishing and maintaining imetelstat manufacture and supply; enforcement of Geron&#x2019;s patent and proprietary rights; managing Geron&#x2019;s business growth; the effects of the COVID-19 pandemic or geopolitical events, and potential competition. Additional information on the above risks and uncertainties and additional risks, uncertainties and factors that could cause actual results to differ materially from those in the forward-looking statements are contained in Geron&#x2019;s filings and periodic reports filed with the Securities and Exchange Commission under the heading &#x201c;Risk Factors&#x201d; and elsewhere in such filings and reports, including Geron&#x2019;s quarterly report on Form 10-Q for the quarter ended June 30, 2023 and future filings and reports by Geron. Undue reliance should not be placed on forward-looking statements, which speak only as of the date of this Current Report on Form 8-K, and the facts and assumptions underlying the forward-looking statements may change. Except as required by law, Geron disclaims any obligation to update these forward-looking statements to reflect future information, events or circumstances.</span></p>
