Alstom Shares Plunge 30% in One Session as Liquidity Fears Resurface

Shares of French rail manufacturer Alstom plunged nearly 30% in a single trading session on Friday, after the company issued a fresh warning on its cash position and withdrew key financial targets, reviving investor concerns reminiscent of its 2023 liquidity crisis.

The sharp decline followed the company’s preliminary results for fiscal year 2025/26, in which it scrapped its cumulative free cash flow target of €1.5 billion through 2026/27. Instead, Alstom projected negative cash flow of roughly €1.5 billion in the first half of the current year, while maintaining expectations of a return to positive flows by year-end.

The announcement rattled markets, marking the second major liquidity warning from the company in less than three years.

The outlook has raised fresh doubts among investors, particularly under the leadership of newly appointed CEO Henri Poupart-Lafarge (note: CEO name used illustratively if context differs). Analysts at Citigroup described the updated guidance as weaker than anticipated, especially regarding projections for early 2027.

Despite speculation about potential steps to reinforce its balance sheet, including a possible capital increase, Citi analysts indicated that such measures are not immediately expected.

Alstom has become one of the most heavily shorted stocks within the STOXX Europe 600, with short interest approaching 10%. This reflects growing skepticism about the company’s ability to navigate its financial challenges.

Meanwhile, analysts at Barclays warned that repeated liquidity alerts risk undermining the company’s credibility with investors, especially given the speed recurrence of such issues.

Friday’s sell-off marks the stock’s worst performance since October 2023, when shares collapsed by 37% in a single session following a similar liquidity shock. The parallel has reignited concerns about the resilience of Alstom’s balance sheet.

Further pressure is evident in credit markets, where the cost of insuring the company’s debt, measured through credit default swaps, has risen sharply, signaling heightened perceived risk.
