• Free cash flow is cash generated from operations less replacement capital expenditure (net of disposal proceeds), less interest paid (net), income taxes paid, payment of lease liabilities and includes contingent consideration received on the disposal of Group businesses. In the current year the definition has been refined to include contingent consideration received without requiring restatement for prior year as deferred consideration arose during the current year. • Acquisition related items comprise deferred consideration payments relating to the retention of former owners of businesses acquired, transaction costs and expenses, professional fees for new and target acquisitions, adjustments to previously estimated earn outs, impairment charges related to intangible assets recognised on acquisition of businesses and goodwill impairment charges. Customer relationships, technology and brands amortisation, the impact of unwinding acquisition related deferred consideration to present value and any associated tax are considered by management to form part of the total spend on acquisitions or are non-cash items resulting from acquisitions and therefore are also included as adjusting items. 32 Definitions • Adjusted earnings per share is earnings before exceptional items, acquisition related items, intangible asset amortisation arising on acquisitions and before profit/loss on disposal of Group businesses. • Adjusted operating profit is earnings before exceptional items, acquisition related items, amortisation of intangible assets arising on acquisitions, profit/loss on disposal of Group businesses, net finance expense and income tax expense. • Adjusted operating profit margin is adjusted operating profit as a percentage of revenue. • Adjusted operating profit (pre property profit) is earnings before exceptional items, profit on disposal of Group properties, acquisition related items, amortisation of intangible assets arising on acquisitions, profit/loss on disposal of Group businesses, net finance expense and income tax expense. • Adjusted operating profit (pre property profit) margin is adjusted operating profit (pre property profit) as a percentage of revenue. • Free cash flow conversion is free cash flow as a percentage of adjusted operating profit.

36 During the financial year ended 31 December 2025, the Group has adopted a new reporting structure which better reflects the Group’s strategy. The Group is now organised into four geographical areas: Island of Ireland, Great Britain, Northern Europe and Iberia. The operating segments are now aligned with these geographical areas and better align with how the Board manages the business, assesses performance and allocates capital and resources for organic and inorganic growth: • Island of Ireland - comprising Chadwicks, Woodie’s, MacBlair and MFP (divested 31 May 2025) • Great Britain - comprising Selco, Leyland SDM, TG Lynes, CPI EuroMix and StairBox • Northern Europe - comprising Isero and Polvo in The Netherlands and IKH in Finland • Iberia - comprising Salvador Escoda and Mercaluz (acquired 30 April 2026) in Spain Comparative figures for H1 2025 have been restated to reflect the new structure. The realignment has no impact on the Group’s consolidated financial results. Information is provided in Appendix 5(a) and 5(b) showing the results under the original segment structure in place at 30 June 2025. Grafton Group plc – Interim Results 2026
