• No material change to FY26 second half and full year guidance
• Tariff developments in the US, including IEEPA struck down and Section 122 introduced
• Estimated net cost impact of US tariffs at lower end of previously indicated range

Reliance Worldwide Corporation Limited (ASX: RWC) ('RWC' or 'the Company') today confirms its trading outlook for the year ending 30 June 2026 (FY26). Based on nine months trading ended 31 March 2026, there is no material change to the FY26 second half and full year guidance issued on 17 February 2026. All guidance - including regional and Group outlook, FY26 net tariff impact, cash flow conversion, capital expenditure, D&A, net interest, effective tax rate and cost savings - is reaffirmed.Since RWC reported its half year results, there have been two significant US tariff developments. Firstly, the US Supreme Court struck down International Economic Emergency Powers ACT (IEEPA) based tariffs, and a Section 122 tariff (10% levy on most imported goods) has been introduced. RWC has lodged a claim for a refund of IEEPA tariffs previously paid. Secondly, from 6 April 2026, Section 232 tariffs on steel, aluminium and copper apply to the full customs entry value on a tiered basis. Notwithstanding these changes, RWC's estimate of the tariffs impact on operating earnings (EBITDA) remains as announced on 17 February 2026, with the full year net cost impact expected to be at the lower end of the previously indicated range of between US$25 million and US$30 million.RWC has no direct exposure to the war in Iran or the closure of the Strait of Hormuz. Higher oil prices have driven increases in resin, logistics and energy costs, which are being offset through price increases. At this point, RWC does not expect the war in Iran will materially impact its FY26 operating earnings, but prolongation of the war may impact the outlook for FY27.

For FY26, the full year net cost impact of US tariffs is expected to be at the lower end of the previously indicated range of between US$25 million and US$30 million. For FY27, the full year estimated net cost impact is unchanged at US$5 million to US$7 million (excluding any tariff refund).

At this point, RWC does not expect the war in Iran will materially impact its FY26 operating earnings, but prolongation of the war may impact the outlook for FY27.
