Aug 5 (Reuters) - Molson Coors ( TAP/A ) forecast a bigger

drop in its annual profit on Tuesday, hit by tariff impacts on

costs of aluminum it uses for its beverage cans amid

macroeconomic uncertainty in the U.S.

President Donald Trump's fluctuating trade tariff policies

have pressured consumer spending in the U.S. and caused

customers to pare back on discretionary spending such as

alcohol.

The annual forecast change comes as a result of "the

anticipated ongoing macroeconomic impacts on the industry, our

lower-than-expected U.S. share performance, and

higher-than-expected indirect tariff impacts on the pricing of

aluminum," CEO Gavin Hattersley said in a statement.

The company, which produces its beer locally at breweries in

Colorado faces a 50% tariff on aluminum metal shipped into the

U.S. since June, when Trump doubled it from 25%.

Shares of the company were down about 1% in premarket

trading.

The company expects annual adjusted earnings per share to

fall 7% to 10%, compared to its prior forecast of a low

single-digit rise.

It expects net sales for the year to decline 3% to 4%,

compared with previous expectations of a decline in the low

single-digits.

The Blue Moon witbier maker in January had bought an 8.5%

stake in an $88-million deal that gives it exclusive rights to

market British company Fevertree Drinks' ( FQVTF ) cocktail

mixers and tonic water in the U.S., in a bid to capture the

domestic demand for non-alcoholic drinks.

Both companies had agreed to equally split the costs of the

10% tariff to be imposed on UK imports to the U.S. in June.

The company's net sales fell 1.6% to $3.2 billion in the

second quarter ended June 30, but came ahead of analysts'

estimate of $3.1 billion, according to data compiled by LSEG.

It posted underlying earnings per share of $2.05,

beating estimates of $1.83 cents per share.

The company said the quarter benefited from pricing growth

and favorable timing of U.S. shipments despite soft

macroeconomic conditions.
