DETROIT — General Motors narrowed its 2026 earnings guidance and raised its free cash flow expectations after beating Wall Street's third-quarter expectations. 

The Detroit automaker also announced a new multiyear stock buyback of $20 billion after GM completed a $6 billion share repurchase program that was announced in January. GM did not disclose a specific time to complete the program.

Here's how GM performed in the third quarter, compared with average estimates compiled by LSEG:

• Earnings per share: $3.70 adjusted vs. $3.63 expected
• Revenue: $50.02 billion vs. $48.7 billion expected

The new guidance includes adjusted earnings before interest and taxes of between $14.5 billion and $15.5 billion, or $12.75 to $13.75 adjusted earnings per share, and adjusted automotive free cash flow of between $11.5 billion and $12.5 billion.

That compares with its raised guidance from July that included adjusted EBIT of between $14 billion and $16 billion, or $12 to $14 adjusted EPS, and adjusted automotive free cash flow of $9.5 billion to $11.5 billion.

Wall Street analysts were mixed before the report on whether GM would update its guidance Tuesday amid concerns of slowing sales and rising commodity costs.

GM on Tuesday said it expects commodity inflation costs to be around $2 billion, which was the high end of its previous guidance. That includes higher costs for logistics and dynamic random-access memory, or DRAM, chips that are impacting multiple industries.

While the inflationary costs were at the automaker's high end of guidance, GM said its gross tariff costs are expected to be at the low end of its expected $2.5 billion to $3.5 billion range. Warranty costs are expected to be at high end between $1 billion and $1.5 billion, GM said.

"GM is performing well, and we are working hard to continue our momentum despite growing inflationary pressures through strategic investments in new products and services, and through improved quality and operating efficiency," GM CEO Mary Barra said Tuesday in a letter to shareholders.

The automaker also said the costs of its pullback in all-electric vehicles announced last year were "substantially completed," saying it has recorded $11.2 billion in such charges since the second half of last year, including paying $4.6 billion of $7.4 billion in cash through the third quarter.

The company's net income attributed to stockholders was $3.3 billion during the third quarter, up roughly $2 billion from a year earlier.

GM's North American operations continued to lead the automaker's results, accounting for $3.6 billion of its $4.1 billion in adjusted EBIT results during the third quarter.

GM's 2025 third-quarter results included $48.59 billion in revenue, net income attributable to stockholders of $1.3 billion and earnings per share of $2.80 adjusted.
