Is GOSS (Gossamer Bio, Inc.) Halal or Haram?

Based on our AAOIFI-standard shariah screening, GOSS is Not Halal (Haram) and is not considered permissible for Muslim investors. It failed 2 of 4 compliance screens. Its debt-to-market-cap ratio of 241.39% exceeds the ≤33% threshold. Its cash & securities ratio of 163.66% exceeds the ≤33% threshold.

Gossamer Bio, Inc. is a clinical-stage biopharmaceutical company focused on discovering and developing therapeutics for immunology, inflammation, and oncology. Its clinical pipeline includes GB002, an inhaled inhibitor for pulmonary arterial hypertension, and GB004, an oral treatment targeting inflammatory bowel disease. For Muslim investors using AAOIFI standards, Gossamer Bio is currently classified as Not Halal (Haram). Although its core medical research passes the business activity screen, the stock fails multiple financial ratios, meaning it cannot be included in a shariah-compliant portfolio at this time. The primary issue for Islamic finance compliance lies in the company's capital structure. Gossamer Bio carries excessive debt, with a debt-to-market capitalization ratio of 241.4%, and highly inflated cash and interest-bearing securities at 163.7% of its market cap, both well over the strict 33% limit. Since the underlying business of developing life-saving therapeutics is permissible, halal investors should monitor the company's balance sheet in the future. If Gossamer Bio significantly reduces its debt load and cash reserves relative to its market valuation, it could potentially pass AAOIFI screens down the line. Gossamer Bio, Inc. operates in the Healthcare sector under the Biotechnology industry and is headquartered in San Diego, CA, US. The company is led by CEO Faheem Hasnain and employs approximately 144 people.

GOSS was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. GOSS passed 2 of these 4 screens.

GOSS was last screened on 2026-04-27. Shariah compliance status can change as companies report new financial data, acquire new businesses, or shift revenue streams. We recommend checking back periodically for the most up-to-date screening results.
