Stone Executive is committed to the highest standards of social, environmental, and ethical responsibility. We expect our suppliers, contractors, and business partners to share these commitments and operate in a lawful, professional, and sustainable manner that respects human rights and supports positive environmental and social outcomes.

Sustainability considerations are embedded in our decision-making processes, including procurement activities. We believe responsible sourcing contributes to sustainable growth by reducing risk, improving efficiency, and creating long-term value.

These Supplier Standards of Conduct (“Standards”) set out the minimum expectations for all suppliers providing goods or services to Stone Executive. Suppliers are expected to align their policies, practices, and procedures with these Standards and promote compliance throughout their own operations and supply chains.

Suppliers must comply with all applicable laws and regulations. Where legal requirements and these Standards differ, the higher standard should be applied where permitted by law.

Our values

Odgers is guided by four core values:

• Excellence
• Respect
• Connectedness
• Integrity

We expect our suppliers to uphold and support these values through the products and services they provide.

Human rights

Stone Executive recognises its responsibility to respect and protect human rights. Suppliers must maintain policies and processes that demonstrate their commitment to internationally recognised human rights standards and comply with all relevant legislation in the countries where they operate.

Suppliers sourcing goods or services from regions with elevated human rights risks must notify us and provide evidence of measures taken to identify, prevent, and mitigate such risks.

Stone Executive takes its obligations under the Modern Slavery Act 2015 seriously and expects suppliers to do the same.

Forced labour

Suppliers must not use or support any form of forced, bonded, indentured, prison, slave, or compulsory labour.

Practices prohibited by the International Labour Organization (ILO), including withholding wages, retaining identity documents, or restricting freedom of movement, are strictly forbidden.

Suppliers should implement controls to prevent worker exploitation by labour providers, recruitment agencies, or subcontractors and must actively work to prevent human trafficking within their operations and supply chains.

Child labour

Suppliers must not employ individuals under the age of 15 or below the legal minimum working age, whichever is higher.

Appropriate safeguards should include age verification procedures, management training, and communication of child labour requirements to subcontractors and suppliers.

Fair compensation

Workers must be paid accurately, regularly, and on time, receiving at least the legal minimum wage or prevailing industry wage, whichever is higher.

Suppliers must provide all legally required benefits, including paid leave, pensions, statutory insurance, healthcare benefits, maternity and parental leave, and other applicable entitlements.

Overtime must be voluntary and compensated in accordance with applicable laws and contractual obligations.

Working hours

Suppliers must comply with all applicable laws regarding working hours, rest periods, overtime, and days worked.

Workers must receive all legally required leave and time off. While occasional overtime may be necessary, suppliers should manage operations to minimise excessive working hours and maintain safe, healthy, and productive working conditions.

Freedom of association

Suppliers must respect employees’ rights to freedom of association and collective bargaining without discrimination, intimidation, retaliation, or interference, and must comply with all applicable legal requirements.

Health and safety

Suppliers are expected to maintain safe and healthy working environments and comply with all relevant health and safety legislation.

At a minimum, suppliers must:

• Comply with Stone Executive’ health and safety requirements when working on our premises.
• Follow agreed permit-to-work and method statement procedures.
• Report all incidents and near misses related to contracted work.
• Provide health and safety policies, management arrangements, and insurance documentation upon request.

Environmental responsibility

Stone Executive is committed to reducing the environmental impact of its operations and supporting sustainable development. Suppliers should maintain environmental commitments and standards comparable to our own or demonstrate progress toward achieving them.

We encourage suppliers to support our environmental objectives by:

• Reducing energy, water, paper, and other resource consumption.
• Lowering carbon emissions in line with climate science and global sustainability goals.
• Minimising waste and diverting waste from landfill wherever possible.

Ethical business practices

Integrity is fundamental to our relationships with suppliers.

Suppliers must operate ethically and comply with all applicable anti-corruption, anti-bribery, anti-fraud, anti-money laundering, and tax regulations.

Appropriate policies, procedures, and controls should be maintained to prevent:

• Human rights abuses
• Corruption and bribery
• Fraud and financial crime
• Conflicts of interest
• Tax evasion
• Improper gifts, payments, or inducements

Confidentiality and information security

Suppliers must maintain effective cybersecurity measures and information security controls to protect personal, confidential, and proprietary information.

Suppliers must implement safeguards appropriate to the sensitivity of the information they access, process, or store on behalf of Stone Executive and comply with all applicable data protection and privacy laws.

Privacy and data protection

Suppliers processing personal information on behalf of Stone Executive must implement appropriate technical and organisational measures to protect such data and ensure compliance with relevant privacy and data protection legislation.

Unauthorised use, disclosure, or loss of personal information must be prevented and reported where required.

Prevention of tax evasion

Suppliers must not engage in or facilitate tax evasion and must comply with all applicable legislation, including relevant provisions of the UK Criminal Finances Act 2017.

Reasonable policies and procedures should be maintained to prevent tax evasion facilitation by employees, contractors, agents, affiliates, and subcontractors.

Physical security

Suppliers, contractors, and visitors must comply with our security requirements while working with us.

Visitors must:

• Follow site access and authorisation procedures.
• Remain escorted where required.
• Refrain from photography or recording without prior approval.
• Comply with applicable laws and security protocols.
• Take responsibility for personal belongings.
• Follow any additional site-specific security requirements.

Insurance

Suppliers must maintain adequate and appropriate insurance coverage, including public liability, product liability, and professional indemnity insurance where applicable.

Evidence of insurance must be provided upon request, and suppliers must promptly notify us of any material changes in coverage.

Subcontracting

Suppliers must obtain our written approval before subcontracting any part of the services or supply arrangements.

Diversity, equity and inclusion

Inclusion is a core principle of Stone Executive's culture.

Suppliers are expected to foster diverse and inclusive workplaces and supply chains by:

• Treating all individuals with dignity and respect.
• Complying with anti-discrimination legislation.
• Maintaining fair and transparent recruitment practices.
• Providing workplaces free from discrimination, harassment, bullying, and inappropriate behaviour.
• Ensuring equal opportunities regardless of age, disability, ethnicity, religion, gender, gender identity, marital status, parental status, pregnancy, sexual orientation, social background, or any other protected characteristic.

Suppliers should be able to demonstrate their commitment to diversity and inclusion when requested.

Compliance and continuous improvement

These Standards establish the minimum expectations for all current and prospective suppliers.

Suppliers are encouraged to implement effective management systems that support continuous improvement, including:

• Identifying and assessing compliance risks.
• Implementing appropriate controls and mitigation measures.
• Monitoring performance and reviewing effectiveness.
• Promptly reporting incidents and compliance concerns.

Failure to comply with these Standards may result in a review of the supplier relationship, corrective action requirements, or termination of contracts. Stone Executive reserves the right to audit suppliers against these Standards.

These Standards may be updated periodically. Compliance with them is in addition to any contractual obligations between Stone Executive and its suppliers. Where a conflict exists between these Standards and a contract, the contract shall prevail.

Non-compliance with these Standards may constitute a breach of contract.
