Compliance, ethics and regulatory excellence Culture of ethics At McKesson, we believe that integrity is the foundation of our culture and is critical to our long-term success. We work to inspire and enable McKesson employees to act with integrity in all we do, and we are committed to complying with the laws and regulations that apply to our business operations. Regulatory excellence As a company in the healthcare industry, we are subject to a wide range of complex and evolving regulatory requirements. We fulfill our ICARE principles and work to maintain the trust of regulators, the public, and other stakeholders by following the laws and regulations that apply to us. In FY22, regulatory excellence was explicitly integrated into our business strategy playbook as a key foundational discipline. We are committed to regulatory excellence in all aspects of our business operations. Throughout FY21, we engaged in focused training and discussed “tone from the top and middle” with senior leaders on their role in driving a culture of regulatory excellence. For example, our General Counsel Organization led an interactive workshop on regulatory excellence with senior leaders. At our Senior Leaders Meeting in early FY22, our CEO and Chief Compliance Officer each highlighted the importance of regulatory excellence, particularly given McKesson’s role in healthcare. Compliance and ethics leadership and oversight McKesson’s compliance program is focused on preventing, detecting and responding to compliance, ethics and regulatory issues. Compliance is an enterprise-wide responsibility shared by every employee, and it starts with the commitment of our leaders to foster a culture of compliance and ethics and regulatory excellence throughout our operations. While our business leaders are responsible for managing compliance risks, Legal and Compliance functions assist management with subject matter and program expertise to help McKesson stay ahead of compliance and regulatory risks. Our Chief Compliance Officer is aided by a Compliance and Ethics Organization which includes designated compliance officers for each of our businesses and multiple subject matter experts. The Chief Compliance Officer oversees and monitors implementation of our programs and meets regularly with our Executive Operating Team and the Compliance Committee of the Board to discuss the compliance program. In FY22, regulatory excellence was explicitly integrated into our business strategy playbook as a key foundational discipline.
