Reliance Worldwide Shares Bounce as Tariff Impact Eases and Guidance Holds

Reliance Worldwide Corporation shares (ASX:RWC) rallied today after the plumbing and heating products manufacturer reaffirmed its full-year earnings guidance and signalled that US tariff costs are tracking toward the lower end of expectations, providing relief to a market that has punished the stock amid trade policy uncertainty.

The RWC share price sits 4.77 percent higher at A$3.19 into the close of the day, recovering some ground after a bruising period that has seen the stock fall 17 percent year-to-date and 35 percent over the past five years. The bounce came as management delivered a trading update following nine months of operations through 31 March 2026, explicitly stating that no material changes have been made to assumptions underpinning regional and group outlook, net tariff impact, cash flow conversion, or cost savings.

Why Are RWC Shares Higher?

At the heart of the move was the company’s refined assessment of US tariff costs. Reliance Worldwide now expects the FY26 net cost impact of US tariffs to land at the lower end of its previously flagged US$25 million to US$30 million range, an improvement that suggests mitigation strategies including sourcing shifts and price increases are gaining traction. More significantly for medium-term sentiment, the company maintained its forecast that FY27 tariff costs will drop sharply to just US$5 million to US$7 million, implying the bulk of the trade-related earnings drag is front-loaded and set to ease structurally.

The update also addressed two notable developments in the US tariff regime. The IEEPA-based tariffs that Reliance Worldwide had been paying were struck down by the US Supreme Court and replaced by a Section 122 tariff currently scheduled to expire in July 2026. In response, the company lodged a refund claim on 20 April 2026 for previously paid IEEPA tariffs via the US federal refund portal, though management cautioned that recoverable amounts have not yet been verified and no uplift has been incorporated into current guidance. Additionally, updates to Section 232 tariffs on metals including steel, aluminium, and copper were noted, though the company does not anticipate these changes will materially alter FY26 operating earnings or cash flows based on current estimates.

Beyond tariffs, Reliance Worldwide addressed the impact of escalating Middle East tensions and the US-Iran conflict on its operations. Management stated that the current geopolitical situation is not expected to materially affect FY26 operational earnings, despite acknowledging that higher oil prices are feeding through to increased costs for resin, logistics, and energy. The company emphasised it is offsetting these input cost pressures through price rises, supporting the case that margins can be defended in the near term. However, management issued a forward-looking caution, noting that a sustained conflict extending into FY27 could influence operating conditions, leaving the door open to potential headwinds beyond the current financial year.

The guidance reaffirmation comes two months after Reliance Worldwide’s HY26 interim results in February highlighted the difficult operating environment the company faces. That result, which showed margin compression and softer earnings driven by tariffs and weak demand in key markets, sent the stock down approximately 6 percent to around A$3.61. Weak US existing home turnover and elevated mortgage rates have dampened renovation and repair activity, a core driver of demand for the company’s SharkBite push-to-connect fittings and other plumbing products. Against that backdrop, the decision to hold guidance rather than cut it has been interpreted by markets as a sign of relative resilience.

Reliance Worldwide has also deployed capital to support shareholder returns in recent months, announcing dividends and on-market buy-backs totalling more than A$120 million. The buy-back programme, which includes a US$15.3 million tranche paid out in early April, has been viewed by some market participants as a signal of management confidence that the shares are undervalued, and provides technical support during periods of weakness.

Looking ahead, the duration and intensity of Middle East conflict, and the pace of recovery in housing turnover will all have a say in whether the company is able to deliver on its FY27 outlook and justify a sustained re-rating from current depressed valuation levels. Markets will be watching for any shift in the Section 122 tariff regime ahead of its July 2026 expiry, as well as updates on the IEEPA refund claim, which represents unpriced optionality if amounts are confirmed and received. While today’s update removes some near-term uncertainty, the long-term underperformance reflects persistent scepticism about growth prospects and margin sustainability in a business highly exposed to cyclical end markets and volatile trade policy.
