NEW YORK, United States — Tiffany's first-quarter profit slid as consumers cut spending and the jeweller issued a pessimistic outlook, sending shares down sharply Wednesday.

The strong dollar is creating intense pressure on international sales.

The retailer's revenue also tumbled 7.4 percent to $891.3 million, well short of the $924.1 million that Wall Street had expected, according to a survey by Zacks Investment Research.

Tiffany said it expects per-share earnings this year to fall in the single-digit percentage range from last year, and also expects a decline in per-share earnings similar to the first quarter.

Profit fell 16.6 percent to $87.5 million, or 69 cents per share. Earnings, adjusted for pretax gains were 64 cents per share, which was four cents short of analyst projections.

In the Americas region, total sales fell 9 percent to $403 million on softness in spending by US customers and tourists. Sales in the Asia-Pacific region fell eight percent to $238 million and sales in Europe fell nine percent to $97 million.

Looking ahead, the company expects full-year profit to fall "by a mid-single-digit percentage" as well as a drop in upcoming second-quarter profit.

Tiffany shares which have fallen 16 percent this year, fell 4 percent, or $2.63, to $61.22 before the opening bell.
