Analysis · AVBP · Life Sciences
ArriVent's 10-Q confirms the Q2 loss already reported, but adds two material items: the USPTO granted an ex parte reexamination of a key firmonertinib patent, and the company raised $140 million through its ATM program during the first half. The patent challenge is a direct threat to the lead asset's IP protection, while the ATM sales show ongoing dilution. Cash of $373.1 million provides at least a 12-month runway, but the patent risk and continued equity issuance are the key investor concerns.
