"Our IPO is a major milestone and exciting moment for Power Probe, and we are extremely grateful for the support we've received from investors. Since 1992, we've been growing our business to become a leading developer in the specialised automotive electrical diagnostics market, driven by a relentless focus on innovation and continuously adapting to the rapid evolution of vehicle technology.

Our admission to AIM marks a new chapter in that journey and will enable us to deliver on our ambitious growth plans, including opening a new state-of-the-art US manufacturing facility, which will increase our overall production capacity and bring us closer to our core end markets.

I would like to extend my sincere thanks to everyone who has been part of this journey, especially our dedicated team, without whom none of this would be possible. At the same time, I'd like to welcome our new shareholders and look forward to delivering our next phase of the Group's story as a public company."

COMPANY HIGHLIGHTS

• Founded in 1992, and headquartered in Charlotte, North Carolina, USA, Power Probe has grown to become an internationally renowned brand with a suite of products across seven segments: powered circuit probes, testing kits, measuring tools, soldering, lighting, accessories, and private brands.
• The Group's range of electrical diagnostic tools and accessories is compatible with all major vehicle engine types and manufacturers, and Power Probe's distinctive red branding, including the iconic pen design of its flagship powered circuit probes, has made Power Probe instantly recognisable to professional service technicians and mechanics across the Company's core markets.
• The Group's testing and measuring tools are available through all major distribution channels, and the Group has strong relationships with highly regarded professional tool companies, including Snap-on, Matco Tools, MAC Tools (part of Stanley Black & Decker, Inc.), and Cornwell Quality Tools, who each distribute the Group's branded products alongside their own-brand tools. These brands have extensive and deep-rooted links into mechanics in the US and UK, the ultimate end users of the Group's products.
• The historical growth of the Group has been supported by continuous innovation, both in incremental advancements made to existing product lines and the development of new products incorporating unique technologies. The Group launched eight new products during 2024, six new products in calendar year 2025 and has 15 new products available to be launched from calendar year 2026, augmenting its existing 120+ strong product portfolio. The Directors believe that new products with additional functionalities will bring with them higher gross margins, further underpinning the Group's growth plans.
• Furthermore, the Directors believe the Group is well positioned to benefit from a number of positive, long-term market tailwinds. Expenditure on vehicle maintenance tends to be inelastic due to the importance of automotive transport, while the overall size and rate of demand for automotive maintenance and repair is expected to grow as the total global Car Parc increases, the average age of vehicles within the Car Parc rises, and vehicle complexity grows. According to independent research commissioned by the Company, the global market opportunity for the Group's products is expected to reach $2.2 billion by the end of 2032.[1]
• The Group has grown considerably in recent years, increasing Group revenue from approximately $25.0 million in the 12 months ended 31 December 2022 to approximately $31.3 million in the 12 months ended 31 December 2024, a CAGR of approximately 12%. The Group's underlying EBITDA has increased rapidly, from approximately $4.8 million to approximately $8.3 million over the same period, a CAGR of approximately 31%.
• This strong rate of growth has continued in the first half of 2025, with Group revenue for the period of $20.5 million, gross profit of $8.6 million, and underlying EBITDA of $5.3 million. In particular, the Directors believe that strong sales of recently launched products in the six month period ending 30 June 2025 evidences the return on investment deriving from the Group's focus on innovation.
• The Directors intend to adopt a progressive dividend from Admission as a result of their confidence in the Group's growth profile and cash generative business model. The Company will target a dividend payout ratio of profit after tax in the region of 50% with the first dividend payments expected to be made in 2026.
