Brickworks (ASX:BKW) said it expects to recognize a post-tax non-cash impairment charge of roughly AU$55 million to Brickworks North America in its fiscal first half results, subject to finalization, audit processes, and board approval, according to a Tuesday filing with the Australian bourse.

Meanwhile, the company's property earnings before interest, taxes, depreciation, and amortization is expected to be higher in the fiscal first half compared with the previous corresponding period due to stable capitalization rates and no significant change in the value of the Property Trust, the filing said.

The company's fiscal-year results are pending finalization and audit, set to be released on March 20, according to the filing.

Shares fell almost 9% in morning trade Tuesday, earlier hitting their lowest since April 2023.
