Chaleit Holdings plc

(“Chaleit”, the “Company”, or together, with its subsidiaries, the “Group”),

Intention to Float on AIM

Chaleit Holdings plc, the specialist cyber security consultancy, is pleased to announce its intention to float on the London Stock Exchange’s AIM Market. The Company is seeking the admission of its entire issued and to be issued ordinary share capital to AIM (“Admission”), with commencement of dealings expected to occur on 7 October 2026. On Admission, the Company would trade under the ticker ‘CHA’.

The Company intends to raise approximately £1.6 million on Admission by way of a placing of new and existing ordinary shares and a direct subscription (together, the “Fundraising”), with an anticipated market capitalisation on Admission of approximately £11.2 million. The net proceeds of the Fundraising receivable by the Company are intended to provide additional resources and financial flexibility to support the Group’s organic growth strategy, which is already under way, including the expansion of its sales and delivery capability.

Strand Hanson Limited is the Nominated and Financial Adviser to Chaleit and Oberon Investments Limited is the Company’s sole broker.

Investment Highlights

Cyber security is an enduring enterprise requirement, supported by increasing dependence on technology and data, evolving threats, regulation and the adoption of artificial intelligence, in a UK market that remains fragmented.

Chaleit has developed its culture around trust, transparency, professional integrity and long-term relationships, applying these principles both to its clients and within the organisation. The Directors consider this particularly important in a professional services business whose value depends substantially on the knowledge, judgement and engagement of its people.

Chaleit combines deep technical capability with engineering, advisory expertise and experienced judgement. Its model seeks to combine the institutional disciplines associated with larger professional services organisations with the client proximity, specialist expertise and continuity of a smaller consultancy.

Since incorporation in 2021, Chaleit has established international operations, developed its own client base and built a profitable and cash generative business.

A significant proportion of revenue is recurring, reflecting Chaleit’s development beyond predominantly point-in-time technical engagements into broader and continuing client relationships.

Chaleit has invested in developing institutional knowledge alongside that gained through technical work and client relationships, principally through a research programme conducted in collaboration with academia and a number of high-quality international blue-chip organisations.

Overview

Chaleit is a penetration testing and offensive security consultancy, examining technology from the perspective of a malicious attacker to reveal how vulnerabilities arise, how systems can be compromised, and how organisations can respond before those vulnerabilities are exploited.

Chaleit has also built a broader consultancy encompassing AI and language model security, cloud security and development security operations engineering, and cyber advisory, governance and compliance work, applied individually or in combination according to its clients’ needs. The Group also invests in extending its knowledge beyond individual client relationships. Experience gained through technical practice and continuing client engagement is complemented by structured research and engagement with senior cyber security practitioners and academia.

The Board

On Admission, the Board will comprise two Executive Directors and two Independent Non-Executive Directors. Dan Haagman, the Group’s Founder and Chief Executive Officer, is supported by Jody Hyde, Chief Financial Officer (CFO) and Chief Operating Officer (COO), Ken Ford, Independent Non-Executive Chairman, and, on Admission, Rob Naylor as Independent Non-Executive Director.

Prof. Dan Haagman, Founder and Chief Executive Officer of Chaleit, commented: “Admission to AIM represents an important next stage in Chaleit’s development and will support our ambition to accelerate the growth of the business.

“Chaleit’s mission is to challenge, support and drive our clients’ cyber security capability and visibility, helping them to build stronger, more resilient organisations. We have built enduring relationships with our clients by combining deep cyber security expertise with evolving AI capabilities to help them address increasingly complex security challenges. As those challenges and requirements evolve, we are able to broaden our initial remit, deepen our relationships and generate recurring revenues for Chaleit.

“We believe Chaleit is well positioned to capitalise on the significant growth opportunities across the cyber security sector, particularly in the UK, US, Australia and Singapore. Admission to AIM will provide us with the capital to invest in our growth plans, further develop our cyber security and AI capabilities, and pursue those opportunities.”

The Admission Document, which will contain full details about the applicant and the Admission of its securities, will be available on the Company’s website at chaleitplc.com from the date of Admission.
