Currently, Spectrum and its affiliates have two oncology drugs in late stage and active development: ROLONTIS, a novel long-acting granulocyte colony-stimulating factor, analog for chemotherapy-induced neutropenia, and Poziotinib, a novel pan-HER inhibitor under investigation for non-small cell lung cancer tumors with either EGFR or HER2 exon-20 insertion mutations.
Spectrum Cayman is owned 99% by Spectrum and 1% by Spectrum Pharmaceuticals International Holdings, LLC, a Delaware limited liability company
(“Spectrum Holdings”). Spectrum Holdings is the sole general partner of Spectrum Cayman and Spectrum is the sole managing member of Spectrum Holdings.

Subject to applicable legal requirements, in addition to the arrangements described above, one or both of the Reporting Persons may also purchase additional securities of the Issuer from time to time in open market or private transactions, depending on their evaluation of the Issuer’s business, prospects and financial condition, the market for the Issuer’s securities, other developments concerning the Issuer, other opportunities available to the Reporting Persons, and general economic, money market and stock market conditions. In addition, depending upon the factors referred to above and subject to applicable legal requirements, the Reporting Persons may dispose of all or a portion of their securities of the Issuer at any time.
