GM Axle Supplier Strike Adds Supply Chain Risk amid Fragile Earnings

What happened

The UAW strike against a key GM axle supplier continues without talks, threatening production of high-margin trucks and SUVs that underpin GM's earnings. This supply disruption compounds existing headwinds from EV writedowns, China restructuring, and tariff mitigation, which the DeepValue report already flagged as draining the margin of safety at ~$85 per share. GM's core North American truck and SUV profits, which fund its capital-intensive transition, face a new operational risk that could amplify if the strike drags on. The company's filings show GMNA margins were only 5.8% in Q4 2024, far from the 8-10% target, and any production loss would pressure guidance further. Without prompt resolution, the strike could accelerate the downside scenario in our thesis, where softer truck/SUV economics compress valuation.

Implication

If the strike persists beyond a few weeks, it may force GM to cut production of its most profitable vehicles, eroding the cash flows that support buybacks and the EV transition. This operational risk, on top of existing EV/China charges, reduces the probability of delivering guided $12-13B EBIT-adjusted for 2025, making the current premium valuation (27x trailing P/E) harder to justify. Investors should reassess positions if the strike widens or threatens full-year output.

Thesis delta

The UAW axle supplier strike introduces a new, previously unmodeled operational risk to GM's near-term earnings. While our bear case already assumes softer truck/SUV economics, this strike could crystallize that scenario sooner, lowering the probability of base and bull outcomes. The upside case now requires a quick settlement plus flawless execution elsewhere, which is a narrower path.
