Third Quarter 2020 Financial Results

  • Cash, cash equivalents and marketable securities were $237.9 million as of September 30, 2020, compared to $226.7 million as of June 30, 2020. This increase is due to the $40.0 million upfront payment received in July 2020 as part of the collaboration agreement with BeiGene offset by cash used in operations. Assembly Bio’s cash position is projected to fund operations into the second half of 2022.
  • Revenues from collaborative research were $34.6 million for the three months ended September 30, 2020 compared to $4.2 million for the same period in 2019. This includes the recognition of $31.0 million under the collaboration agreement with BeiGene as well as reimbursements incurred under the collaboration agreement with AbbVie Inc. (Allergan Pharmaceuticals International Limited prior to AbbVie’s acquisition of Allergan).
  • Research and development expenses were $26.9 million for the three months ended September 30, 2020, compared to $21.7 million for the same period in 2019. The increase was primarily due to an increase of $4.0 million in research and development expenses related to the HBV program. Research and development expenses include non-cash stock-based compensation expenses of $2.8 million for the three months ended September 30, 2020 and $2.5 million for the same period in 2019.
  • General and administrative expenses were $11.7 million for the three months ended September 30, 2020 compared to $8.5 million for the same period in 2019.
