Mercedes-Benz Slides to Yearly Low as Plant Closures and Union Fight Converge

Mercedes-Benz shares fell 3.1% to EUR 42.28 as management warned two German plants could close amid a wage dispute and EV transition costs.

Mercedes-Benz shares skidded 3.1% on Wednesday to close at EUR 42.28 on Xetra, dragging the stock uncomfortably close to its 52-week low of EUR 42.01. The retreat crystallizes a dilemma the Stuttgart automaker can no longer defer: how to fund an expensive electric and software transition while its home-country cost base bleeds competitiveness.

At the heart of the sell-off is an escalating standoff over German production economics. Management has signaled that, absent a change to the current cost structure, two domestic plants could be shuttered — an assembly facility and a powertrain site. Works council accounts confirm the board has dangled exactly that threat, alongside plans to shift further capacity abroad.

The numbers behind the warning are stark. According to company figures, labor costs in Eastern Europe run roughly 75% below German levels. Mercedes has already expanded its Hungarian plant in Kecskemét to 400,000 units while domestic capacity has shrunk, leaving investors to weigh how deeply the core business must be cut to close the gap.

A Contract Fight With a Deadline

The immediate flashpoint is the upcoming wage round. The board wants an unpaid increase in weekly working hours to 38 for German plants, paired with reductions to Christmas and holiday pay as well as profit-sharing. CEO Ola Källenius has been blunt that the cost per labor hour must come down.

IG Metall, for its part, opens negotiations on October 7 with a demand of at least 5% for employees. The peace obligation expires on October 31, meaning warning strikes could begin in November and disrupt output at premium manufacturing lines. The union has already shown its muscle — summer protests drew tens of thousands of participants.

Politics is circling too. Back on September 17, three German states hosting major automakers pushed for faster government support, citing the historic upheaval bearing down on the industry.

Where the Bull Case Still Lives

Not everything points downward. Mercedes is pressing ahead on the technology front, striking a partnership with Wayve on the same day the plant warnings landed. The deal commits the London-based startup's autonomous driving software for integration into Mercedes' own MB.OS operating system, with a rollout into series vehicles targeted within two years. The arrangement brings Level 2 autonomy to market faster and more cheaply, and it reflects a pragmatic willingness to lean on outside software expertise rather than build everything in-house.

The company has also shelved development of costlier Level 3 systems for broader model lines such as the electric C-Class — a sign that even Mercedes must trim investments to preserve capital.

Analyst Stephen Reitman of Bernstein Research remains constructive, rating the stock "Market-Perform" with a price target of EUR 56. In his view, German premium manufacturers are holding up better against new Chinese rivals than the current industry mood suggests. Continued relative strength in sales, plus product refreshes like the updated EQS flagship with its 800-volt architecture, could unlock meaningful upside from present valuation levels.

What Determines the Next Move

The pivotal gauge remains the adjusted operating margin, and its defense hinges on how the labor confrontation resolves. If working-time changes are pushed through without wage compensation, the fixed-cost base in German manufacturing would get immediate relief. If not, a costly protracted dispute looms while the electric overhaul simultaneously absorbs heavy capital.

The downside scenario is a hardened front between board and workforce. Should management actually trigger plant closures, hefty one-off charges for severance and restructuring would weigh on net income for quarters. A softer luxury market would compound the damage by neutralizing the pricing power that has propped up margins, and any further erosion of the operating margin — whether from richer wage settlements or persistent underutilization of German sites — invites additional share-price declines.

For traders, the line in the sand is the 52-week low at EUR 42.01. Holding that level on a daily closing basis leaves room for stabilization; a sustained break could widen the downtrend as broad-based hedges kick in.

The calendar is tightly packed. The first bargaining round begins October 7, offering a read on the union's willingness to compromise. Management reports third-quarter 2026 figures on October 28, revealing the true margin trajectory. Then, on October 31, the peace obligation lapses — and without an agreement on key points for site security by then, industrial action is likely to darken sentiment further.
