AIM Rule 26

AIM Rule 26

Below is all of the information and documentation required of us to enable compliance with Rule 26 of the AIM Rules. The information provided here was last updated on 2nd January 2018 and is disclosed in accordance with Rule 26.

Country of incorporation and main country of operation

Osirium Technologies plc (“Osirium” or “the Company”) is incorporated in England and Wales (Registration Number 9854713). Osirium’s main country of operation is the United Kingdom.

Business Description

Osirium is an award winning, privileged access management and cyber-security specialist. Our industry leading product suite protects critical data from cyber attacks and internal threats.

We are a UK based cyber-security software provider that protects critical IT assets, infrastructures and devices by preventing targeted cyber-attacks from directly accessing Privileged Accounts, removing unnecessary access and powers of Privileged Account users, deterring legitimate Privileged Account users from abusing their roles and containing the effects of a breach if one does happen.

What is a Privileged Account?

A Privileged Account has elevated permissions and rights compared with an average user account. An organisation’s IT assets, infrastructures and devices such as directory services, application tiers, databases, network and security appliances and backup and service infrastructures are all operationally managed by employees or third party outsourcers. By virtue of their function, these employees and third parties are issued with Privileged Account access to ensure the uptime (i.e. less downtime), performance and security of an organisation’s IT assets, infrastructures and devices. Functions that require access to Privileged Accounts include database and system administrators, network engineers, IT security and audit practitioners, data centre operators, application developers and cloud custodians. Privileged Account users therefore have extensive access to IT systems and sensitive data.

Responsibilities of the board of directors and its committees

There is no compulsory regime of corporate governance to which the directors of a UK company admitted to AIM must adhere to over and above the general fiduciary duties of skill and diligence imposed on such directors under English law. However, the Directors acknowledge the importance of the principles set out in the QCA Corporate Governance Code for Small and Mid-Size Quoted Companies (“QCA Code”). Although the QCA Code is not compulsory for AIM quoted companies, the Directors intend to apply the principles as far as they consider appropriate for a company of its size and nature.

The Board comprises five directors, two of whom are executive directors and three of whom are non-executive directors, reflecting a blend of different experience and backgrounds. The Board considers Simon Lee, Simon Hember and Steve Purdham to be independent Non-Executive Directors under the criteria identified in the UK Corporate Governance Code (September 2014).

The Board meets regularly and is responsible for strategy, performance, approval of any major capital expenditure and the framework of internal controls. To enable the Board to discharge its duties, all directors receive appropriate and timely information. Briefing papers are distributed to all directors in advance of Board meetings. The Board has established audit and remuneration committees with formally delegated duties and responsibilities and with written terms of reference. Each of these committees meet regularly and at least twice a year. From time to time separate committees may be set up by the Board to consider specific issues when the need arises. Further details on the audit and remuneration committees are set out below.

Audit Committee

The duties of the Audit Committee are to consider the appointment, re-appointment and terms of engagement of, and keep under review the relationship with, the Group’s auditors, to review the integrity of the Group’s financial statements, to keep under review the consistency of the Group’s accounting policies and to review the effectiveness and adequacy of the Group’s internal financial controls. In addition, it has received and reviewed such reports as it from time to time requests from the Group’s management and auditors. The Audit Committee has met at least twice a year and has unrestricted access to the Group’s auditors. The Audit Committee comprises Steve Purdham, Simon Lee and Simon Hember and has been initially chaired by Simon Lee.

The directors acknowledge that relevant corporate governance guidelines, including the QCA Code, state that the Audit Committee should not be chaired by the Chairman of the company. The directors have considered the membership of the Audit Committee carefully and have concluded that, given the current composition of the board, Simon is the most appropriate choice to be its Chairman. The board regularly reviews the effectiveness of the Audit Committee. Once any further appointments have been made to the board, the Audit Committee will be reviewed to bring its composition into line with corporate governance best practice guidance.

Remuneration Committee

The Remuneration Committee has responsibility for reviewing and determining, within agreed terms of reference, the Group’s policy on the remuneration of Senior Executives, Directors and other key employees and specific remuneration packages for Executive Directors, including pension rights and compensation payments. It is also responsible for making recommendations for grants of options under the New Share Option Scheme. It has met not less than twice a year. The remuneration of Non-Executive Directors is a matter for the board and no Director may be involved in any discussions as to his or her own remuneration. The Remuneration Committee comprises Steve Purdham, Simon Lee and Simon Hember and is chaired by Steve Purdham.
