General Motors announced Tuesday it expects to receive a $500 million refund on tariffs following a Supreme Court ruling that struck down certain trade levies imposed during the Trump administration.

The Detroit automaker disclosed the anticipated refund in a letter from CEO Mary Barra to shareholders on Tuesday. The refund stems from the Supreme Court's decision that some of Trump's emergency tariffs were illegally imposed.

The expected refund has prompted GM to revise its financial outlook. The company now projects earnings before interest and taxes of $13.5 billion to $15.5 billion for this year, an increase from its previous forecast range of $13 billion to $15 billion.

Looking ahead to 2026, GM anticipates paying $2.5 billion to $3.5 billion in tariff costs, down from an original estimate of $3 billion to $4 billion. The reduction reflects the impact of the Supreme Court's ruling on the company's future tariff obligations.

The Supreme Court's decision has opened the door for other companies to seek similar refunds on tariffs they paid under the Trump administration's trade policies. GM appears to be among the first major corporations to publicly quantify the financial benefit it expects to receive from the ruling.
