the EV margin
trap.

The seven OEMs do not operate in isolation. They share battery suppliers, compete for the same lithium supply, and face the same regulatory mandates. The margin compression across multiple companies simultaneously is partly explained by shared input costs: when CATL prices batteries, it affects Tesla, Ford, VW, and Hyundai at the same time. The network below maps the relationships. Drag any node to rearrange.

The chart below shows adjusted operating margin for each OEM's automotive operations, as reported in their annual filings. Tesla is included because its entire business is EVs. There is no legacy combustion segment to subsidize losses. The years 2019 through 2024 span a period that begins before the EV transition commitments were made and ends with the first full cycle of EV program losses flowing through income statements.

The divergence beginning in 2022 is the central fact. Tesla's operating margin peaked at 17.2% in FY2022 and fell to 7.3% in FY2024, a 9.9 percentage point collapse in two years driven by a series of aggressive price cuts that were designed to defend volume but eroded unit economics. Toyota and Hyundai, both of which delayed aggressive battery EV commitments in favor of hybrid programs, maintained and improved their margins. VW Group and Stellantis, which committed most aggressively to full battery EV product lines, saw the steepest declines. Stellantis moved from 12.8% in 2023 to -2.0% in 2024. VW moved from 6.5% to 2.3%. These are not rounding errors. These are structural shifts.

Ford sits in the middle. Its overall automotive margin has been under pressure since 2022, largely explained by the Blue Oval EV segment, which is discussed in section three. GM, the outlier with the most stable reported margins, has not broken out its EV program losses with the same transparency as Ford or Tesla.

The filings tell a consistent story across all seven OEMs: EV unit economics are worse than publicly stated, EV program losses are larger than EV-specific revenue for most of the group, and the timeline for profitability has been pushed out each year. Tesla is the partial exception (it is profitable at the company level), but its margin compression is the most dramatic in the dataset, and the company's public statements about pricing power and margin maintenance did not match what the 10-Ks subsequently showed.

The transparency gap is itself a finding. Ford chose to disclose Blue Oval EV as a separate reporting segment starting in 2023, making it the most transparent of the group. Tesla is fully public and discloses automotive gross margin each quarter, but its entire business is EVs so no traditional/EV split exists. GM has declined to provide segment-level EV disclosure. VW and Stellantis disclose losses in aggregate terms but not broken out by unit. Toyota and Hyundai disclose the least.

Ford is the only major OEM that separately reports its electric vehicle business as a discrete segment with its own revenue, cost, and EBIT lines. The Blue Oval EV segment (also referred to as Model e) was carved out of Ford's reporting in Q1 2023, providing three years of audited loss data.

What makes Ford's disclosure valuable is not the losses themselves. Analysts have inferred EV losses at every major OEM. What makes it valuable is the detail. Ford breaks out cost of goods sold, gross margin, and EBIT by segment, showing where the loss originates. In 2023, cost of goods sold for the Model e segment was $6.5 billion against $1.8 billion in revenue. Gross margin was negative before a single dollar of R&D or SG&A was allocated. That is the structural problem: the vehicles are being sold for less than the direct cost to build them, and volume alone does not close that gap at current battery prices.

The contrast between earnings call language and annual filing disclosures is consistent across all seven OEMs. The pattern: calls describe the transition as on track, near term headwinds as manageable, and profitability as an imminent milestone. Tesla adds a specific variation: the calls described pricing cuts as a deliberate choice made from a position of margin strength, while the 10-Ks showed the margin consequences of those same cuts.

The pattern is not unique to any single company. The gap between calls and filings appears in every case we reviewed. The language on calls is conditional and forward looking ("we expect," "we remain confident"). The filings contain the actual numbers. That gap is where the analysis lives.
