Press Release

On October 12, 2023, Alvotech issued a press release (“Press Release”) announcing that it has received a complete response letter ("CRL") from the US Food and Drug Administration ("FDA") for Alvotech’s Biologics License Application for AVT04, a biosimilar candidate to Stelara® (ustekinumab). As expected, the CRL noted that certain deficiencies, which were conveyed following the FDA’s inspection of the company’s Reykjavik facility that concluded in March 2023, must be satisfactorily resolved before the application can be approved. No other deficiencies in the application were noted by the FDA. A copy of the Press Release is furnished herewith as exhibit 99.1.
