STMicroelectronics N.V.

Item 16B. Code of Ethics

We have adopted written standards of business conduct and ethics (“Code of Conduct”), as well as related policies, which are designed to promote honest and ethical business conduct. Our Code of

Conduct, which is applicable to all our employees and senior managers, sets clear expectations on the way we conduct business and make our decisions, fostering a culture of integrity.

We expect all our employees and senior managers to comply with our Code of Conduct and related policies, to adhere and advocate for integrity in the workplace.

We have amended, and will continue to amend, our Code of Conduct and related policies as needed to reflect regulatory and other changes. In January 2026 we released an updated version of our Code of Conduct to include, among others, specific guidance on trade compliance and the responsible use of AI, as well as practical simplified guidance clarifying ST's expectations in other key areas covered by our Code of Conduct. We also redesigned our Code of Conduct to enhance readability and engagement.

Our Code of Conduct provides that if any employee or senior manager acts in contravention of the principles it sets forth, we will take appropriate steps in terms of the procedures in place for fair disciplinary action. In cases of severe breaches, such action may include dismissal. Our Code of Conduct is available on our website in the corporate governance section, at https://investors.st.com/governance/compliance-ethics-privacy.
