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

Gossamer Bio regains Nasdaq minimum bid price compliance after 1-for-80 reverse split

Neutral Impact 2 of 5 legal/regulatory Written later

Gossamer Bio received a Nasdaq letter on September 25, 2026 confirming it has regained compliance with the $1.00 minimum bid price requirement, closing the matter. The company had completed a 1-for-80 reverse stock split on September 10, 2026, with split-adjusted trading beginning September 11, 2026. The filing shows the listing issue is resolved, but it does not report any change to financial results.

Key points

  • Nasdaq letter dated September 25, 2026 confirms compliance with the minimum bid price rule under Nasdaq Listing Rule 5450(a)(1)
  • The matter followed a Nasdaq letter received April 8, 2026, after the stock failed to trade at $1.00 or more for 30 consecutive business days
  • 1-for-80 reverse stock split effective September 10, 2026; split-adjusted trading began September 11, 2026
