An investment in our common shares involves a high degree of risk. You should carefully consider the risks and uncertainties described in the 2024 10-K, in addition to other information in this report, when evaluating our business and before deciding whether to purchase, hold or sell our common shares. Each of these risks and uncertainties, as well as additional risks and uncertainties not presently known to us or that we currently consider immaterial, could harm our business, financial condition, results of operations and/or growth prospects, as well as adversely affect the market price of our common shares, in which case you may lose all or part of your investment. Except as described below, there have been no material changes from the risk factors disclosed in Part I, Item 1A. Risk Factors in the 2024 10-K.

No assurances can be given that we will be able to continue to consistently manufacture clinical quantities of our product candidates in accordance with cGMP from a master and working cell bank system, or at a cost-effective or commercially viable scale, for one or more of our product candidates.

We previously completed a cGMP production run of two of our clinical-stage product candidates from a customized two-tiered cGMP cell banking system. However, at this time, no assurances can be given that we will be able to consistently continue to produce production lots in the future in compliance with cGMP or do so at a cost-effective or commercially viable scale. See also the risk factor titled, “The manufacture of our cell therapy product candidates is complex, highly regulated and subject to a multitude of risks. We have limited experience manufacturing our product candidates on a clinical scale and no experience manufacturing on a commercial scale. Any failure to manufacture our product candidates in sufficient quantities in accordance with applicable quality standards and regulatory requirements and at acceptable costs, may result in significant clinical development delays or impair our ability, or that of a strategic collaborator, to obtain approval for or commercialize our product candidates,” set forth in “Item 1A. Risk Factors” of our 2024 10-K.
