Athenex, Inc. announced that in terms of product sales guidance, the Company is limiting financial guidance to the existing Athenex product portfolio only. In 2020, the Company recorded a significant amount of revenues from international customers as a result of the global pandemic. However, it does not see these revenues as recurring in nature. The Company continues to expand its product portfolio. The Company is affirming the guidance it provided on May 6, 2021, as it currently expects its product sales in 2021, excluding any royalties from Klisyri®, to be in line with 2020 levels.
