U.S. Automakers Post Q3 Gains While Grappling With Rising Material, Fuel and Tariff Costs

01
Core Event
In the third quarter of 2026 the Detroit “Big Three” – General Motors, Ford and Stellantis – reported modest revenue increases (GM + 2.9%, Ford + 2%, Stellantis + 1%) and continued strong sales of light-duty trucks and larger vehicles. Executives warned that higher prices for steel, copper, memory chips, diesel fuel and lingering tariffs are creating a multi-billion-dollar cost headwind that could strain profitability in 2027.
02
Background & Context
Since 2025 the Trump administration has imposed additional tariffs on imported steel, aluminum and copper, raising the cost of key automotive inputs. The federal electric-vehicle (EV) tax credit of $7,500 expired, removing a major price incentive for U.S. consumers. Global demand for copper and computer memory chips has surged, tightening supply and lifting prices.

| GM’s projected material, chip and diesel cost impact | up to $2 billion this year | GM earnings call |
| GM’s current tariff expense | about $2.5 billion (lower than earlier forecasts) | GM CFO Paul Jacobson |
| Ford’s estimated commodity, memory and logistics headwind | about $2 billion YoY | Ford CEO Jim Farley |
| EV share of U.S. new-car sales (Sept.) | ~6% | Edmunds |

Official Statements & Responses
General Motors CFO Paul Jacobson said sustained high material prices will make “heading into next year…more challenging.” Ford CEO Jim Farley echoed the pressure, estimating a $2 billion YoY headwind from commodities, memory chips and logistics, while noting growth in software services and parts as offsets. Stellantis executives pledged more detailed cost data in the fourth quarter and highlighted strong pickup sales.

Why It Matters
Tariff-driven material cost hikes, tighter chip supplies and the loss of the EV tax credit create a “perfect storm” for U.S. manufacturers. Higher-margin trucks sustain revenue, but profitability of emerging EV lines is under pressure, prompting firms to lean more heavily on hybrids. Tesla’s recapture of roughly 52% of U.S. EV sales underscores the advantage of an established EV portfolio when rivals scale back investment.
07
Conflicting Reports & Gaps
No source provided a definitive figure for the total incremental cost impact across all three automakers; GM and Ford each quoted a $2 billion headwind, but Stellantis’ specific estimate was not disclosed. GM cited refunds as part of its $2.5 billion tariff expense, but the refund amount was not quantified.
08
What’s Next
GM, Ford and Stellantis will disclose more granular cost breakdowns in their fourth-quarter earnings releases, slated for early 2027. Analysts will watch for adjustments to production plans for EVs and hybrids as manufacturers respond to tariffs, commodity prices and evolving consumer demand.
