12:36 PM EDT, 04/29/2025 (MT Newswires) -- General Motors ( GM ) plans to update its full-year outlook later in the week amid tariff uncertainty, while the automaker delivered better-than-expected first-quarter results on Tuesday.

The company postponed its earnings call to Thursday, citing "recent reports regarding updates to trade policy," GM said in a statement. During the call, it will discuss first-quarter results and its updated outlook for 2025 as the initial guidance "does not contemplate the potential impact of tariffs," according to the company.

US Commerce Secretary Howard Lutnick said on Tuesday that President Donald Trump is set to sign an order later in the day that is expected to ease the impact of 25% auto tariffs, Reuters reported.

"The future impact of tariffs could be significant," Chief Financial Officer Paul Jacobson said on a call with reporters, according to a separate Reuters report. "We're telling folks not to rely on the prior guidance, and we'll update when we have more information around tariffs."

Media reports showed that GM suspended its share buyback program until it has more clarity on the impact of US duties. The company didn't respond to MT Newswires' request for confirmation of the repurchase program's suspension and Jacobson's guidance remark.

In January, the automaker said it expected adjusted earnings to be in a range of $11 to $12 per share for the ongoing year. The current consensus on FactSet is for non-GAAP EPS of $9.95.

For the March quarter, GM's adjusted EPS rose to $2.78 from $2.62 last year, ahead of the Street's view for $2.68. Revenue increased 2.3% to $44.02 billion, surpassing the average analyst estimate of $43.23 billion.

Revenue in North America climbed to $37.39 billion from $36.1 billion in the 2024 quarter, while international sales declined to $2.43 billion from $3.08 billion. Vehicles sales rose to 1.45 million units from 1.35 million last year. Sales in the US market rose to 693,000 vehicles from 594,000.
