Financial Results (preliminary)

• At September 30, 2022, the Company had cash and cash equivalents of $168.2 million, compared to $122.9 million at December 31, 2021.

Revenues are recognized as a result of U.S. product sales of ZTALMY, Marinus’ BARDA federal contract and European collaboration with Orion Corporation.
  • Net product revenues of $0.56 million were recorded for each of the three and nine months ended September 30, 2022 as a result of the commercial launch of ZTALMY in late July 2022. No net products revenues were recorded in periods prior to the launch.
  • The Company recognized $1.8 million and $5.1 million in BARDA federal contract revenue for the three and nine months ended September 30, 2022, respectively, as compared to $1.1 million and $4.8 million for the same periods in the prior year, respectively.
