CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

This Quarterly Report on Form 10-Q, or the Quarterly Report, includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and other securities laws. The statements contained herein that are not purely historical, are forward-looking statements. Forward-looking statements include statements about our expectations, beliefs, plans, objectives, intentions, assumptions and other statements that are not historical facts. Words or phrases such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “ongoing,” “plan,” “potential,” “predict,” “project,” “will” or similar words or phrases, or the negatives of those words or phrases, may identify forward-looking statements, but the absence of these words does not necessarily mean that a statement is not forward-looking. For example, we are making forward-looking statements when we discuss our business strategy and plans, our clinical and pre-clinical development program, including timing, milestones and the design thereof, including acceptance of regulatory agencies of such design and lifting of the current clinical hold, the potential opportunities for and benefits of the BacteriOphage Lead to Treatment, or BOLT, platform, the potential of our product candidates and the sufficiency of financial resources and financial needs and ability to continue as a going concern. However, you should understand that these statements are not guarantees of performance or results, and there are a number of risks, uncertainties and other important factors that could cause our actual results to differ materially from those expressed in the forward-looking statements, including, among others:

For a detailed discussion of these and other risks, uncertainties and factors, see Part I, Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2024. All forward-looking statements contained in this Quarterly Report speak only as of the date hereof. Except as required by law, we are under no duty to (and expressly disclaim any such obligation to) update or revise any of the forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this Quarterly Report. Comparisons of results between current and prior periods are not intended to express any future trends, or indications of future performance, and should be viewed only as historical data.
