Croma Security Solutions Group Plc

("CSSG", "Croma", "the "Company" or the "Group")

Acquisition of Southern Security Services

Croma Security Solutions Group plc (AIM:CSSG), the AIM listed innovation and service-focused security solutions provider, is pleased to announce the completion of the acquisition of Southern Security Services Limited ("SSS"), an established electronic security and specialist locksmith business based in Poole, Dorset from its owner-manager, Pierre Grandjean

The total consideration for the acquisition , subject to adjustments for cash, debt and working capital at completion, is £0.55 million. This comprises an initial payment of £0.46 million and a deferred balance of £0.09 million, payable subject to the achievement of earn-out targets over the 12 months following completion.

Included in the transaction is SSS's single trading outlet, a freehold property valued at £0.4 million. The acquisition will be funded from the Group's existing cash reserves.

For the year to 31 December 2025, SSS generated revenues of £1.04 million and EBITDA of £0.13 million and had a net asset value of £0.43 million.

SSS is a principally a provider of electronic security, generating revenue from the sale, supply, installation and maintenance of locking systems and safes, intruder alarms, CCTV, access control, and automated security doors and gates. Founded in 1983, the business has a strong reputation for providing premium security advice, SSS's primary customer focus is commercial and includes key clients such as local authorities and healthcare‑sector operators.

SSS employs 12 members of staff, all of whom are locally based and will join the Group as part of the acquisition. This team, which is highly experienced in advising on the installation of comprehensive physical and electronic security systems, represents a significant addition to Croma's engineering and advisory capability.

With SSS operating from Poole, in close proximity to a number of the Group's existing clients, this is a highly complementary local acquisition. The business is already well known to the Group, creating immediate opportunities to share projects and allocate resources efficiently.

Pierre Grandjean will remain with the business for a period of 12 months following completion to support a smooth transition. Following the expiry of the earn‑out period, he may, subject to mutual agreement, continue in a role with the Group on a longer‑term basis.

Roberto Fiorentino, Chief Executive Officer, commented: "We are very pleased to announce the acquisition of SSS. We know Pierre and the team well, and they have built an excellent group of engineers whose experience aligns closely with the projects the wider Group is currently delivering. As we welcome them into the Group, we see immediate opportunities for synergy through the integration of SSS within our operations. We are confident this acquisition will prove to be a strong strategic fit."

Pierre Grandjean, Managing Director of SSS Security Systems, said: "Southern Security Services Ltd has developed into a strong and well‑established business. Joining the Croma Group represents an important next step for the company and creates opportunities to broaden its capabilities and scale its operations. The nature of Southern Security Services' work closely aligns with projects already being delivered by the Group in other regions, including larger programmes that are strategically important to both businesses. Combining the expertise of both teams will enhance delivery capability and support the pursuit of similar opportunities across the Group. I look forward to Southern Security Services Ltd becoming an integral part of the Croma Group."

The Group's network currently stands at 17 security centres, stretching from its headquarters in Southampton, across the Midlands and up to the Northwest. Croma services a range of sectors including health, education, leisure and entertainment, and utilities, and is trusted by national brands, including multiple NHS Trusts, with their complex security needs.

Croma's growth strategy is focused on establishing a national security network. In 2023, it sold its man-guarding business Vigilant for £6.5m, which has provided the capital to fund the expansion of the business. Croma is a proven acquirer of local, traditional locksmith businesses, which are developed into its network of modern security centres, offering both total security solutions and locksmith services to retail and commercial customers. The new security centres benefit from extended product ranges, centralised group services, and both a local and national customer base. Since the sale in 2023, Croma has added new businesses to its network, and has a strong pipeline of further locksmiths stores to be acquired into the network.

Croma is listed on the AIM market of the London Stock Exchange. Founded in 1970, it is headquartered in Southampton and has over 95 employees.
