We are a biotechnology company focused on discovering, developing and commercializing first-in-class therapeutic antibodies designed to harness the immune system for the treatment of oncology indications with significant unmet medical need. We have extensive experience in research and development in immuno-oncology, having been pioneers in the understanding of natural killer cell, or NK cell, biology, and later expanding our expertise in the tumor microenvironment, tumor antigens and antibody engineering fields. We have built, internally and through our business development strategy, a broad and diversified portfolio including an approved product, three clinical product candidates and a robust preclinical pipeline. We have entered into collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and Sanofi, to leverage their development capabilities and expertise, and we have received upfront and milestone payments and equity investments from our collaborations of an aggregate of approximately $550 million over the last ten years. We may be eligible to receive an aggregate of approximately $5.5 billion in future contingent payments from existing collaboration agreements and any license agreements that become effective upon the exercise by our collaborators of options to license future product candidates. We believe our product candidates and clinical development approach are differentiated from current immuno-oncology therapies and have the potential to significantly improve the clinical outcome for patients with cancer.
