United Therapeutics is in the business of saving lives, and that is not limited to our focus on patients. We also put innovative efforts into mitigating our impact on the planet and prioritizing environmental stewardship. This focus has been a central part of our strategy for over a decade. The cornerstone of our commitment to our planet is demonstrated in the industry-leading design and construction of our facilities in Silver Spring, MD; Research Triangle Park (RTP), NC; and Melbourne and Jacksonville, FL.Our commitment to social responsibility is rooted in our founding as a mission-driven company, intent on developing therapies, and one day a cure, for the rare, life-threatening lung condition known as pulmonary arterial hypertension (PAH). To fulfill this mission, we have developed an ever expanding series of FDA-approved medicines and devices to treat PAH, and have launched Lung Biotechnology PBC, a public benefit corporation with the goal of using our innovative organ manufacturing programs to cure PAH and other diseases by creating an unlimited supply of transplantable lungs and other organs. To our knowledge, this is the first public benefit corporation subsidiary of a public biotech company.We strive to always operate with an eye toward corporate responsibility, environmental sustainability, and solid governance. These practices have long been embedded into our business at all levels. We have a strong tone at the top, with leaders who care deeply about improving the lives of patients, empowering our people, and making our planet and the communities in which we live and work better. We are guided by doing the right thing, while also relentlessly pushing to always do better. We also have an active, engaged, and diverse Board of Directors, which oversees our key business strategies and objectives, our risk management process, our compliance program, and key aspects of our corporate social responsibility program.We have dedicated teams to ensure that patients have access to our treatments. One team works with insurers to strive for the best possible coverage for our drugs, and we are proud of the results we have achieved. We also have a variety of options for patients who may still need financial assistance to pay for our treatments. And we have a dedicated team, ASSIST (Access Solutions and Support Team), that helps our patients and their families navigate this complex area. Our ASSIST Associates are ready to work with them, their health care providers, and specialty pharmacies to help them understand their insurance coverage, educate them about available financial assistance options, and answer their questions.One of our strategic objectives is to achieve our goals by doing the right thing and using the highest ethical standards. This is evidenced by our commitment to a robust compliance program, ethical operations, scientific integrity, responsible sourcing, and environmental sustainability. Ethics is one of our core values, and we continue to enhance our programs across all of these areas. One important aspect of our approach to business ethics is a well-defined set of Compliance Principles that outlines how we behave, and clear leadership attributes that we expect from all Unitherians.
