Dec 1 (Reuters) – Australia’s Treasury Wine Estates said on Monday it expects to recognise a non-cash impairment of its U.S.-based assets, with all A$687.4 million ($450.25 million) of its goodwill for the region likely to be written off, sending its shares to their lowest in more than a decade.

The write-down comes after adopting more conservative long-term growth assumptions for its Americas business, the company said.

Shares of the country’s largest standalone winemaker fell as much as 6.4% to A$5.45 in early trade, touching their lowest level since August 2015. The broader benchmark S&P/ASX 200 index was largely flat as at 2331 GMT.

The final impairment amount and allocation to assets will be concluded as part of its 2026 interim results, the winemaker said.
