General Motors' profit and revenue declined in its second-quarter but the automaker easily topped expectations and the company stuck by its full-year financial outlook that it lowered in May.

For the three months ended June 30, GM earned $1.89 billion, or $1.91 per share. A year earlier the company earned $2.93 billion, or $2.55 per share.

Stripping out certain items, earnings were $2.53 per share. That handily beat the $2.34 per share analysts polled by FactSet were calling for.

Revenue declined to $47.12 billion from $47.97 billion, but still topped Wall Street's estimate of $45.84 billion.

Shares still declined 3% before the opening bell Tuesday.

And in a letter to shareholders Tuesday, CEO Mary Barra remained optimistic about the electric vehicle market.

"Despite slower EV industry growth, we believe the long-term future is profitable electric vehicle production, and this continues to be our north star," she wrote. "As we adjust to changing demand, we will prioritize our customers, brands, and a flexible manufacturing footprint, and leverage our domestic battery investments and other profit-improvement plans."

The company maintained its full-year financial forecast. In May General Motors lowered its profit expectations for the year as the carmaker braced for a potential impact from auto tariffs as high as $5 billion in 2025.

The Detroit automaker said at the time that it anticipated full-year adjusted earnings before interest and taxes in a range of $10 billion to $12.5 billion. The guidance includes a current tariff exposure of $4 billion to $5 billion.

A month later GM announced plans to invest $4 billion to shift some production from Mexico to U.S. manufacturing plants. The company said at the time that the investment would be made over the next two years and was for its gas and electric vehicles.

President Donald Trump signed executive orders in April to relax some of his 25% tariffs on automobiles and auto parts, a significant reversal as the import taxes threatened to hurt domestic manufacturers.

Automakers and independent analyses have indicated that the tariffs could raise prices, reduce sales and make U.S. production less competitive worldwide. Trump portrayed the changes as a bridge toward automakers moving more production into the United States.

The tariffs ordered by Trump are hitting the entire auto sector, which sends vehicles and parts across the northern and southern borders of the U.S. repeatedly as they are assembled. The Center for Automative Research says that a uniform 25% tariff on all trading partners would have an increased cost of $107.7 billion to all U.S. automakers and an increased cost of $41.9 billion for the Big Three automakers in Detroit, Stellantis, GM and Ford.

GM reported its financial results a day after Jeep maker Stellantis said that its preliminary estimates show a 2.3 billion euros ($2.68 billion) net loss in the first half of the year due to U.S. tariffs and some hefty charges. Stellantis will release its financial results for the first half of the year on July 29.
