Kathmandu's share price dropped by 8 per cent after the company said its sales over the Christmas and Boxing Day period had been disappointing.
By late morning, shares in the outdoor goods retailer were down by 22 cents at $2.52.
The company said at its annual meeting on November 23 that, based on trading during the first 15 weeks of the fiscal year, its first-half profit was expected to be "strongly above" last year, depending on how its summer sale performed.
Now, it appeared that a 4 to 8 per cent gain was likely, it said.
In a statement today, management said sales during December had been below expectations.
