Questcor Pharmaceuticals,

Now a part of Mallinckrodt Pharmaceuticals Mallinckrodt Pharmaceuticals is pleased to bring Questcor and its entire business into our company. The former Questcor organization will be known as the Autoimmune and Rare Diseases business within Mallinckrodt’s Specialty Pharmaceuticals segment. We will continue their focus on the treatment of patients with serious, difficult-to-treat autoimmune and inflammatory disorders, primarily in the fields of neurology, nephrology, rheumatology and pulmonology, areas of medicine which have significant unmet medical needs. A market-leader in specialty pharmaceuticals and medical imaging, Mallinckrodt develops, manufactures and markets products that diagnose serious illnesses and treat pain. Our pharmaceuticals business encompasses branded and generic products as well as the Active Pharmaceuticals Ingredients used to make prescription drugs. Our imaging business focuses on contrast media and delivery systems plus nuclear medicine. Together we will work tirelessly to find more imaginative ways to help more patients, accelerate product development and deliver long-term, above-market growth. Corporate Culture It’s an exciting time to be at Mallinckrodt. Our culture is defined by five hallmarks: high-performing, competitive, collaborative, engaged and trustworthy. There’s a strong sense of purpose, too, as we’re all totally focused on helping patients, whether we’re producing quality products, engaged in customer service or educating healthcare professionals. Our culture encourages collaboration, breakthrough thinking and ownership of meaningful work. We’ll empower you to act in the best interests of our customers and our company. The more you’re alert to opportunities, inspired to take the initiative and ready to make thoughtful decisions, the more successful you will be. Combine your competitive zeal with the passion to improve lives, and you’ll soon find yourself building your career as well as our business.
