LONDON, May 6 (Reuters) - Danish jewellery maker Pandora

cut its annual profit margin guidance on Tuesday due

to a decline in the U.S. dollar and said it is preparing for

various scenarios related to U.S. tariffs that could add tens of

millions of dollars to its costs.

Pandora, whose biggest market is the U.S., said it now

expected a margin on earnings before interest and tax (EBIT) of

around 24% this year, having previously targeted around 24.5%.

It stuck to its guidance of 7-8% organic growth for the year.

Pandora is among the European companies most at risk from

the possibility U.S. President Donald Trump reinstates steep

so-called "reciprocal" tariffs, including a 37% tariff on

Thailand where the jeweller's two factories are located.

These tariffs were implemented, then paused for 90 days to

allow for negotiations. A 10% blanket tariff on imports from all

countries remains in place.

Pandora said that, if the current level of tariffs remains

in place, there would be a cost impact of 250 million Danish

crowns ($38.00 million) this year, and 300 million Danish crowns

annually thereafter.

If the 37% tariff on Thailand resumes, Pandora expects an

impact of 500 million Danish crowns this year, and 900 million

Danish crowns annually thereafter.

"In both scenarios, Pandora will consider further price

increases," the company said, the latest in a string of brands

and retailers to warn of higher U.S. prices for their goods.

Pandora's first-quarter revenue matched analysts'

expectations, and the charm bracelet maker said it would

continue to invest in marketing while acknowledging an

"uncertain" economic backdrop.

Revenue for the first quarter was 7.347 billion Danish

crowns ($1.12 billion), slightly above analysts' median forecast

of 7.310 billion, while Pandora delivered organic growth of 7%.

"We are pleased with how we've started the year, especially

given the very high volatility in the world around us," Pandora

CEO Alexander Lacik said in a statement.
