Ethics and Business Conduct

Ethics and Business Conduct 

Doing what is right because it is the right thing to do is the foundation of Northrop Grumman’s business culture. The reputation that our Company has earned for high legal and ethical standards is one of our greatest business assets. Our goal has never been solely to comply with the law, but to abide by the highest principles of integrity and concern for others.

We strive to conduct business in ways that reflect our Standards of Business Conduct – collectively as a company and as individual employees within the company. Through communications and training, we continually link individuals – including business associates – to Our Values. We must not sacrifice our integrity to achieve business objectives.

Our sense of ethics and doing what is right are the cornerstones of Northrop Grumman’s exemplary reputation. They allow us to gain respect and support within our communities, help provide a competitive advantage in the marketplace, and attract and retain individuals who not only demonstrate, but also demand high standards of business conduct.

Please join us in maintaining Northrop Grumman’s reputation for integrity in the years to come.
