Business Description

Overview Fortress Biotech, Inc. (“Fortress” or the “Company”) is a biopharmaceutical company focused on acquiring and advancing assets to enhance long-term value for shareholders through product revenue, equity holding and dividend and royalty revenue streams. Fortress works in concert with our extensive network of key opinion leaders to identify and evaluate promising products and product candidates for potential acquisition.
