GM Investors Eye Iran War Risks, Tariffs, and EV Write-Downs Beyond Earnings

Detroit’s skyline is a living monument to American industry—Renaissance Center’s towering glass spires, the hum of the assembly lines at GM’s historic Hamtramck plant, and the quiet tension in the air as investors and workers alike brace for the automaker’s Q1 earnings report this morning. While Wall Street fixates on spreadsheets and analyst expectations, here in the Motor City, the stakes feel more personal. This isn’t just about quarterly profits; it’s about the future of the 15,000 Michiganders who still build GM vehicles in-state, the suppliers along I-75 who depend on just-in-time contracts, and the families who’ve staked their livelihoods on an industry in the throes of reinvention—or retreat.

General Motors’ earnings call, set for 8:30 AM ET, arrives at a crossroads. The company is grappling with three seismic forces: the fallout from the Iran war’s disruption of critical mineral supply chains, the Biden administration’s latest round of tariffs on Chinese EV components, and—most pressingly—the billions in write-downs tied to its electric vehicle ambitions. For Detroit, these aren’t abstract market forces. They’re the difference between a plant staying open or another round of buyouts, between the city’s fragile economic recovery and a return to the hollowed-out despair of the 2008 financial crisis.

The EV Write-Downs: A Billion-Dollar Reckoning

The most immediate concern for investors—and by extension, Detroit—is GM’s electric vehicle strategy. The company has already signaled it will take a substantial write-down on its EV investments, a move that reflects both the slowing demand for battery-powered cars and the brutal economics of scaling up production. While the exact figure hasn’t been disclosed in the primary sources, the Wall Street Journal has previously reported that Detroit automakers are collectively writing down billions in EV-related assets, a trend that’s reshaping executive compensation and forcing a reckoning with the pace of the transition.

For Detroit, this isn’t just a financial footnote. The city’s economic revival over the past decade has been closely tied to the auto industry’s resurgence, with GM’s investment in plants like Factory ZERO (formerly Detroit-Hamtramck) serving as a cornerstone. That facility, which produces the GMC Hummer EV and the Chevrolet Silverado EV, employs thousands of UAW workers and supports countless local businesses, from the diners on Conant Street to the machine shops in nearby Warren. A slowdown in EV production—or worse, a pivot away from it—would ripple through the local economy in ways that extend far beyond the assembly line.

Consider the suppliers. Companies like American Axle & Manufacturing, headquartered in Detroit, and Lear Corporation, based in Southfield, have invested heavily in retooling their operations for EV components. A pullback by GM could force these suppliers to scale back operations, lay off workers, or even relocate to states with more favorable incentives. For a city that’s still recovering from the loss of nearly a quarter of its population since 2000, every job matters. The Detroit Regional Chamber estimates that every auto job supports seven additional jobs in the local economy—from healthcare workers to teachers to the baristas at Astro Coffee in Corktown.

The Iran War and Tariffs: Supply Chain Chaos

Beyond the EV write-downs, GM’s earnings will also reflect the impact of two geopolitical wildcards: the ongoing Iran war and the Biden administration’s tariffs on Chinese EV components. The conflict in Iran has disrupted the global supply of critical minerals like lithium and cobalt, which are essential for battery production. While GM has diversified its supply chain in recent years, the volatility has driven up costs and created uncertainty for its EV timeline.

Meanwhile, the tariffs—announced earlier this month—are designed to protect domestic automakers from Chinese competition but come with their own set of challenges. For GM, which sources some components from China, the tariffs could increase production costs, further squeezing margins in an already competitive market. The company has been vocal about its efforts to localize supply chains, including its partnership with LG Energy Solution to build battery plants in Ohio and Tennessee. But for now, the tariffs add another layer of complexity to an already fraught transition.

For Detroit, these supply chain disruptions hit close to home. The city’s logistics and warehousing sectors, which employ thousands of workers, are deeply intertwined with the auto industry. The Port of Detroit, for example, handles millions of tons of auto-related cargo each year, from engines to electronics. Delays or cost increases in the supply chain could trickle down to these workers, many of whom are already struggling with the rising cost of living in a city where the median household income is just $36,000—well below the national average.

Wall Street’s Expectations: A Barometer for Detroit’s Future

Wall Street’s expectations for GM’s earnings are a study in contrasts. Analysts are forecasting a modest profit for the quarter, but the focus will be on the company’s guidance for the rest of 2026. Any hint of a slowdown in EV production or a downward revision to full-year projections could spook investors and send GM’s stock tumbling. For Detroit, that’s more than just a market reaction—it’s a signal about the city’s economic trajectory.

GM’s stock performance is closely watched by local leaders, including Mayor Mike Duggan and the Detroit Economic Growth Corporation. The company’s fortunes are intertwined with the city’s broader revitalization efforts, from the $1.5 billion redevelopment of the Michigan Central Station to the expansion of the Detroit RiverWalk. A strong earnings report could bolster confidence in Detroit’s economic future, while a weak one could raise questions about the sustainability of its recovery.

It’s not just about GM, either. Ford, which is also headquartered in the Detroit area, is facing similar pressures. The two automakers have long been the twin pillars of the local economy, and their fates are inextricably linked. If GM stumbles, Ford could face increased scrutiny from investors, creating a feedback loop that could dampen hiring and investment across the region. For a city that’s still grappling with the legacy of deindustrialization, that’s a risk it can’t afford.

The Human Cost: What This Means for Detroit Workers

Behind the numbers and the market reactions are real people—workers like James Thompson, a third-generation autoworker at GM’s Orion Assembly plant in suburban Detroit. Thompson, who didn’t want to use his real name for fear of retaliation, told a local news outlet last week that he’s worried about the future. “We’ve seen this movie before,” he said. “The company invests in something new, then pulls the plug when it doesn’t work out. I just hope they don’t forget about the people who got them here.”

Thompson’s concerns are shared by many in the UAW, which has been vocal about the need for a just transition to electric vehicles. The union has secured commitments from GM and Ford to invest in EV production and retrain workers, but the pace of change has left some feeling uneasy. “It’s not just about building new cars,” said one UAW official, who spoke on condition of anonymity. “It’s about making sure the workers who built the old ones aren’t left behind.”

For Detroit’s workforce, the stakes are high. The city’s unemployment rate, while improved from its peak during the pandemic, still hovers around 8%—nearly double the national average. Many of the jobs that have returned are in lower-wage sectors like hospitality and retail, leaving workers like Thompson to wonder if the auto industry’s revival will ever fully reach them.

What’s Next for Detroit?

As GM prepares to report its earnings, Detroit is at a crossroads. The city’s economic future hinges on the auto industry’s ability to navigate the transition to electric vehicles while managing the fallout from geopolitical disruptions and shifting market dynamics. For local leaders, the challenge is clear: how to ensure that Detroit’s revival is inclusive and sustainable, not just for the executives in the Renaissance Center but for the workers on the assembly line and the families in the neighborhoods beyond.

One thing is certain: the decisions GM makes in the coming months will have ripple effects that extend far beyond its balance sheet. They will shape the future of Detroit’s workforce, its supply chain, and its economic trajectory for years to come. And for a city that’s spent decades clawing its way back from the brink, that’s a responsibility that can’t be taken lightly.
