These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and while Ocean Biomedical and Aesther may elect to update these forward-looking statements at some point in the future, they assume no obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law. Neither Ocean Biomedical nor Aesther gives any assurance that Ocean Biomedical or Aesther, or the combined company, will achieve its expectations.
