Modern Slavery Statement

Introduction

Callsign opposes all forms of modern slavery, human trafficking, forced labour, and exploitation. We recognize our responsibility to uphold human rights and are dedicated to maintaining the highest standards of integrity and ethical conduct in all aspects of our business.

This statement is made pursuant to Section 54 of the UK Modern Slavery Act 2016 and Federal Decree-Law No. (24) of 2023 on Combating Human Trafficking: This updated and repealed the landmark Federal Law No. (51) of 2006.

Our Business

The Callsign group of companies provide a digital identity platform that uses AI for positive identification of users. The business has a global footprint with key operating bases in the UK, UAE and United States. While our business model presents a low risk of modern slavery, we recognise our responsibility to remain vigilant and ensure that all aspects of our operations uphold the highest ethical standards.

Our Supply Chain

Our supply chain consists mainly of:

• Professional service providers;

• Technology platforms; and

• Office and administration suppliers.

Whilst we do not operate in high-risk sectors; we maintain a zero-tolerance approach to exploitation and require suppliers to meet legal and ethical obligations.

Commitment

We are committed to:

• Preventing modern slavery and human trafficking in all forms;

• Ensuring transparency in our business practices;

• Working only with suppliers who share our values; and

• Continually improving our processes to identify and mitigate risk.

Policies and Practices

To support our commitment, we have implemented the following policies and procedures:

Corporate Social Responsibility Policy

a. Reinforces Callsign’s commitment to conducting business in a socially responsible and ethical manner.

b. Re-states our zero-tolerance stance to modern slavery and our commitment to ensuring it has no place in our operations.

c. Confirms Callsign’s adoption of the Ethical Trading Initiative’s (ETI) Base Code, which is founded on the conventions of the International Labour Organisation (ILO) and is an internationally recognised code of labour practice.

Vendor Code of Conduct:

a. Requires our suppliers to share our commitment to ethical practices. Suppliers must comply with our Vendor Code of Conduct, which includes adherence to anti-slavery principles and compliance with local and international laws.

b. Stipulates the need for a commitment to anti-slavery and compliance with the requirements of the Modern Slavery Act 2015.

c. Mandates a mechanism to enable individuals to raise concerns relating to wrongdoing or malpractice at work i.e., a Whistleblowing or Speaking Up policy.

Employee Screening and Training:

a. Ensures that all Callsign employees and contractors are vetted according to our Colleague Screening Policy.

b. Delivers training to ensure the understanding of roles and responsibilities, including the importance of ethical conduct and personal integrity.

c. Mandates specific Modern Slavery Training to relevant personnel to support the identification and mitigation of associated risk.

Whistleblowing Policy
a. Whilst we will always encourage employees to raise their concerns through their line management, we provide a whistleblowing procedure which includes the ability to raise their concern with an independent body.

Monitoring and Compliance

Callsign has established mechanisms to monitor compliance with our policies and to address any issues related to modern slavery. We conduct routine audits and assurance activities with suppliers to confirm adherence to our standards.

Reporting Concerns

Any employee (including contractors) who suspect modern slavery must report it to:

• A member of ExCo

• The designated compliance contact (Matt Gott – VP Operations)

• Our confidential whistleblowing channel.

Conclusion
