GOSS Gossamer Bio, Inc.
Price Chart
Executive Summary
Gossamer Bio extended the early tender deadline for its exchange offer to exchange up to $181M of 5.00% Convertible Senior Notes due 2027 for new 7.50% Convertible Senior Secured First Lien Notes due 2030, common stock, and warrants. The withdrawal deadline has passed, and the offer requires 98% minimum tender to close, with the final expiration on June 16, 2026.
Actionable Insight
Monitor the June 16 expiration for whether the 98% minimum tender condition is met. If the exchange closes, noteholders will receive a mix of secured debt and equity, significantly diluting common shareholders. The extension suggests the company is still gathering tenders, and the outcome remains uncertain.
Key Facts

- As of June 1, $181,052,000 in aggregate principal amount of Existing Convertible Notes was validly tendered.

Financial Impact
Up to $181M of existing 5.00% convertible notes being exchanged for new secured notes and equity; potential massive dilution from up to 317.6M new shares (current market cap ~$46M).
Risk Factors
- Exchange offer may fail if 98% minimum tender condition is not met.
- If successful, massive equity dilution from up to 317.6M new shares relative to current market cap.
- New 7.50% secured notes increase interest burden and are senior to existing unsecured notes.
