Penumbra, Inc. designs, develops, manufactures, and markets medical devices. The Company offers peripheral vascular and neurovascular devices that help patients suffering from stroke and other neurovascular diseases.

On November 10, 2020, Quintessential Capital Management issued a research report on the Company entitled “Penumbra and its ‘Killer Catheter’.” In it, the report revealed that “Penumbra’s flagship device, the Jet 7 Xtra Flex, has a structural design flaw that makes it prone to critical malfunctioning” and that the “killer catheter” has already malfunctioned [causing the death] of 17 patients and leaving 35 others with brain injuries.”

On December 8, 2020, Quintessential Capital Management published a damaging report entitled “Is Penumbra’s core scientific research authored by a fake person?.” The report accused Penumbra of having engaged in a multi-year scheme to fraudulently produce a substantial portion of scientific literature using a fake character to support its product marketing to healthcare providers across United States and elsewhere.  According to the report, “[the] fraudulent character appears to have been fabricated by management in a reckless attempt to hide its involvement with critical research produced with significant undisclosed conflicts of interest.”

On this news, Penumbra’ stock price fell approximately $16 per share, or 8.3%, during intraday trading on December 8, 2020.
