Trading Update and Response to Shareholder Letter

Newmark Security plc (AIM: NWT), a leading provider of electronic and physical security systems, notes the open letter published today by Thalassa Holdings Ltd. ("Thalassa"), a 21.3% shareholder in the Company. The Board is providing a response to the letter and an update on the Company's current trading and progress with its corporate strategy.

Commenting on the Company's progress, Marie-Claire Dwek, CEO, said: "Our growth strategy is delivering for our shareholders and this is evident in the momentum building within our core business. With revenue and profit weighted to the second half, we are excited by the current outlook.

"We welcome meaningful input from shareholders as we shape Newmark for future success."

Trading update

The Company has made a good start to the current financial year, reflecting the successful execution of its strategy, and it expects to report strong revenue growth for the six months to 31 October 2025 (H1 2026), with a positive impact on profitability. As in previous years, the Company expects performance to be weighted to the second half of the year.

Strong commercial momentum has continued at Grosvenor, the Group's people and data management business, with Human Capital Management's ("HCM") annualised recurring revenue* (ARR) up 36% year-on-year as of Sept 2025 to £3.8 million (Sept 2024: £2.8 million). Significant commercial advancements have also been made with HCM's direct-to-end-user (D2E) strategy in North America, with the sales order book now building. The recent launch of the new GT Tablet, the Group's workforce management solution, is also garnering strong customer interest, and first orders are being placed.

Safetell, the Group's physical security business, has rebounded from a series of delayed installation contracts last year. Some of these contracts have been fulfilled during the current first half, with others expected to be completed during the remainder of the financial year, whilst service and maintenance revenues are also growing.

As previously announced, earlier in the year, the Board initiated a strategic review of Safetell. The Board is seeking to deliver improved shareholder value in accordance with the future direction of the Group, with HCM now Newmark's primary growth engine. The Board can confirm that the strategic review is progressing well, with a cost reduction programme already underway and further savings to be realised. Access Control's ongoing strategy has also been under review, which includes a future product development programme to unlock new growth opportunities.

Response to Shareholder Letter

The Board of Newmark notes the open letter published today from Thalassa, a shareholder in the Company.

The Board welcomes feedback from all its shareholders as its primary objective is to grow and deliver shareholder value. Whilst the Board does not accept a number of the claims put forward in the open letter, it continues to offer the opportunity to meet shareholders for constructive discussions.

The Company would also like to highlight that it has been looking to reshape the Board's composition, which includes the addition of at least one new, independent non-executive director, and further updates will be made in due course.

In line with previous years, the Company will release an AGM statement on the morning of 23 October 2025, which will provide a summary of its operational performance for the fiscal year to date.

*ARR is calculated by annualising revenue recognised in a given month from all clients on deployed HCM subscription contracts
