• Distressed Debt Exchange Launched

  Gossamer Bio initiated an exchange offer for its $200 million outstanding 5.00% Convertible Senior Notes due 2027. The offer aims to reduce the aggregate principal amount of debt to $72 million by exchanging existing notes for a combination of new 7.50% Convertible Senior Secured First Lien Notes due 2030, up to 317.6 million shares of common stock (or prefunded warrants), and up to 150 million purchase warrants for early tenders. This represents a $128 million debt reduction, critical for the company's financial stability.

• Massive Potential Dilution

  The exchange offer, if fully participated, could lead to the issuance of up to 317,647,058 new shares and 150,000,000 purchase warrants. This represents a potential dilution of approximately 199.7% relative to the current outstanding shares, a significant impact on existing shareholders.

• Strong Noteholder Support & Conditions

  Approximately 75.2% of existing noteholders have already entered into a transaction support agreement to tender their notes. The exchange offer is contingent on a minimum participation of 98% of the aggregate principal amount of existing notes, which may be waived.

• Positive FDA Meeting & Drug Data

  The company received confirmation for an in-person Pre-NDA Type B meeting with the FDA in mid-June 2026 for seralutinib in PAH, with an NDA submission expected in September 2026. This follows positive topline results from the PROSERA CT functional respiratory imaging (FRI) exploratory substudy, which demonstrated statistically significant treatment effects and correlations with favorable clinical outcomes, providing structural support for the drug's activity.

This filing outlines Gossamer Bio's multi-pronged strategy to address its severe financial distress, including a going concern warning and Nasdaq delisting notice. The proposed debt exchange is a critical, albeit highly dilutive, measure to restructure $200 million in convertible notes, reducing the principal to $72 million and extending maturities. This exchange, supported by a significant portion of noteholders, is essential for the company's immediate survival and to extend its cash runway. However, it comes at the cost of substantial potential dilution, nearly 200% of current outstanding shares, and requires a massive increase in authorized shares and a reverse stock split to maintain Nasdaq listing. Simultaneously, the positive FDA meeting confirmation and encouraging new data from the PROSERA study for seralutinib offer a much-needed positive development for their lead drug candidate, providing a potential path to NDA submission and future revenue, which is crucial for the company's long-term viability. The market will weigh the immediate, severe dilution against the extended financial runway and the renewed hope for seralutinib's regulatory path, all while the stock trades near its 52-week low.
