Reliance Worldwide (ASX:RWC) reaffirmed its trading outlook for the year ended June 30, first disclosed last February, according to a Tuesday filing with the Australian bourse.

Net cost impact of tariffs on fiscal year operating earnings is estimated to be in the range of $25 million to $30 million, while capital expenditure is expected to be between $25 million and $30 million, an earlier filing showed.

The company anticipates that the war in Iran will not "materially" affect its operating earnings for the full fiscal year, although an extended conflict could influence the outlook for the fiscal year 2027, the filing said.

Shares rose 5% in morning trade on Tuesday.
