AI brief of an SEC Form 8-K · Gossamer Bio, Inc. (GOSS)

Gossamer Bio appoints Gregory Ciongoli to board, adds him to Audit Committee

Neutral Impact 3 of 5 leadership Written later

Gossamer Bio appointed Gregory A. Ciongoli as a Class III director effective September 16, 2026, with a term expiring at the 2027 annual meeting, and also named him to the Audit Committee. The Board determined he is independent under Nasdaq listing rules, and he is a purchaser in the 2026 private placement, so his board seat ties him to securities he has agreed to buy in the company.

Key points

  • Appointed Class III director effective September 16, 2026; initial term expires at the 2027 annual meeting of stockholders
  • Receives a $40,000 annual cash retainer for Board service and a $7,500 annual cash retainer for Audit Committee service
  • Purchased initial closing pre-funded warrants in the 2026 PIPE (initial closing August 24, 2026) and agreed to buy second closing and FDA approval warrants
  • Board determined he is independent under Nasdaq Global Select Market listing requirements
