We would like to take this opportunity to remind our suppliers of our commitment to conduct business with uncompromising integrity. This commitment is clearly established in Code of Conduct. Leidos requires suppliers to conduct themselves in a manner consistent with the principles of our Code of Conduct. In addition, we strongly encourage our suppliers to have proactive and meaningful ethics and compliance programs established within their organizations. We want our suppliers to understand, foster, and mirror the ethical conduct we expect from our employees in all business transactions. If you believe that Leidos or any of its employees or agents has acted improperly or unethically, please report such behavior to the Leidos Ethics Hotline (800) 760-4332. Leidos provides its Code of Conduct for informational purposes only, and makes no representations as to its appropriateness for use outside of Leidos.

Leidos is committed to advancing Global Citizenship in all aspects of our business, including our procurement activities. We understand the potential effects our procurement decisions have both on the environment and in our communities, and we support operating in a socially and environmentally responsible manner including the protection of internationally proclaimed human rights.

We expect our suppliers to comply with all local environmental, health, and safety regulations and encourage them to join us in protecting the environment by informing us of environmentally preferable product offerings, using processes, materials, and transportation methods that support sustainability of the environment throughout the supply chain (e.g., applying energy-efficient, environmentally friendly technologies to reduce waste, and emissions to air, water, and soil). Further, we expect our suppliers to not engage in the discrimination of employees or discriminate in the selection of lower-tier suppliers on the basis of sex, race, color, age, religion, creed, sexual orientation, national origin or citizenship, ancestry, disability, marital status, gender identity, military or veteran status, or any other basis protected by law.
