Code of Conduct

Our Code of Conduct is all about our values, which are shared throughout the Company. It sets clear expectations and provides practical guidelines on the way we conduct business and make our decisions, helping to foster a culture of integrity. It also defines guiding principles for everyone at ST, in line with our value proposition to all stakeholders, and it reflects our values.

  • Integrity: we conduct our business with the highest ethical standards, honor our commitments, deliver on our promises, are loyal and fair, and stand up for what is right.
  • People: we behave with openness, trust and simplicity; we are ready to share our knowledge, encourage everyone’s contribution, develop our people through empowerment, teamwork and training; each one of us is committed and personally involved in the continuous improvement process.
  • Excellence: we strive for quality and customer satisfaction and create value for all our partners; we are flexible, encourage innovation, develop our competences, seek responsibility and are accountable for our actions; we act with discipline, base our decisions on facts, and focus on the priorities.

Our Code of Conduct is available in 10 languages on our website (, our intranet and in our ST Integrity app.

In 2019, we refreshed our Code of Conduct. We updated our compliance and ethics risk assessment and risk mapping exercise, and we continued our compliance and ethics awareness and communication campaign, ‘Building Trust Together’.

Building Trust Together

Building Trust Together started in 2018. It uses a variety of tools to engage employees, managers and third-parties, including face-to-face and town hall meetings, e-learning modules, dedicated intranet, articles, posters, targeted emails and short videos.

Speak up and misconduct reporting

Managers are accountable for maintaining a working atmosphere where employees feel comfortable about speaking up and expressing their concerns freely.
