DIAGEO PLC

Our Code sets out the basis for how we work and conduct business.

It lists key principles which guide our day-to-day operations, decisions

and interactions with colleagues and other stakeholders. Our Code

forms what we stand for as a business and how we demonstrate our

high standards of integrity and ethical behaviour.

All Diageo employees are required to complete our Code of Business

Conduct training annually, via either routine annual training or as part

of new-joiner onboarding.

Additionally, all eligible(1) employees are required to certify that they

have read, understood and complied with our Code of Business Conduct

and supporting global policies during the previous financial year

through an annual compliance certification declaration.

The training is delivered through an interactive e-learning module,

with classroom sessions provided for those without regular

computer access.

In fiscal 25, employees engaged with our Code through local Business

Integrity Day activations. Markets shaped integrity conversations

around their local priorities, supported by global resources and

guidance. This flexibility led to more relevant, resonant sessions that

strengthened understanding, sparked meaningful dialogue, and

reinforced the everyday role of integrity in how we work.
