General Motors Company (GM) Income Statement

The deceleration is broad-based, with 2025Q4 revenue down 5.1% year-over-year and 2025Q2 down 1.8%, indicating weakening demand or pricing power. The lack of R&D expense reported suggests that growth investments may be understated, but the trend points to a mature market with limited volume expansion. Investors should monitor whether this is cyclical or structural, as GM's growth now lags peers like Toyota.

The dramatic compression in gross margin, especially the negative quarter in 2025Q4, suggests that GM is facing higher input costs, warranty expenses, or pricing discounts to move inventory. Compared to Ford's 12.2% and Toyota's 16.7%, GM's current margin is far below peers, implying a competitive disadvantage. This may indicate that GM's product mix is shifting toward lower-margin vehicles or that EV investments are dragging profitability.

The collapse in operating income despite relatively stable SG&A (around $2-3B) indicates that the primary driver is gross margin deterioration, not overhead inefficiency. In 2025Q4, SG&A actually rose to $2.5B while revenue fell, amplifying the negative operating leverage. This suggests that GM's fixed cost base is too high for the current revenue level, and any recovery in margins would require significant volume or cost restructuring.

The disproportionate increase in COGS relative to revenue indicates that GM is absorbing higher material, labor, or warranty costs without passing them to consumers. This is evident in the gross margin decline from 13.7% to 7.6% over the same period. Management's expense discipline appears weak, as SG&A has not been cut proportionally, and the lack of R&D data suggests that innovation spending may be underfunded, potentially harming long-term competitiveness.

This quarter represents a clear break from the prior trend of positive, albeit declining, earnings. The negative gross margin of -2.5% indicates that GM sold vehicles below cost, likely due to aggressive discounting or inventory write-downs. The lasting impact is that GM's profitability trajectory has shifted from moderate to strained, and the company may need to restructure its cost base or product portfolio to regain investor confidence.
