French train maker Alstom cut its full-year outlook on Monday for the second time in 2026, after execution problems on major projects in Germany drove first-half profitability sharply lower and turned its cash-flow forecast negative.
The group said its adjusted core profit margin was around minus 4% in the first half of the financial year, compared with plus 6.4% a year earlier. It lowered its full-year margin forecast to around 1%, from an earlier 6.5% — a downgrade of five and a half percentage points that stunned investors in one of Europe’s largest rail manufacturers.
The bigger shock was cash. Alstom scrapped its previous guidance for positive free cash flow and now expects an outflow of €1.5 billion ($1.7 billion) for the year. It also launched a plan to reduce debt by around €2 billion, as it tries to repair a balance sheet now under intense market scrutiny.
The setback is centred on the Coradia Max programme, a series of regional trains ordered by German states that had been expected to drive production growth this year. Alstom said technical issues and additional testing requirements had extended the certification timeline for the trains, delaying deliveries and weighing on profitability.
The warning came less than seven months after Alstom scrapped a three-year free cash flow target and cut its margin outlook, blaming delays and execution problems on major rolling-stock contracts. That history made Monday’s announcement harder for investors to dismiss as a one-off: the company is now cutting its forecasts for a second time in the same year, over substantially the same kind of problem.
The market reaction was swift. Alstom shares plunged about 30% in early Paris trading, and were still down 26% at €11.80 by 1045 GMT. Analysts at Citi estimated that the negative cash-flow forecast was equivalent to roughly 20% of Alstom’s market capitalisation, and the stock has now lost 54% of its value in 2026 including Monday’s fall.
Alstom also cut its annual production target to around 4,000 rail cars, from a range of 4,400 to 4,500 previously, and lowered its sales outlook to low- to mid-single-digit percentage organic growth, against a previous forecast of around 5%. The cuts matter beyond Alstom itself: the company is a key supplier to rail operators across Europe, and its warning weighed on industrial shares, with the pan-European STOXX 600 index slipping 0.3% in early trading.
For Germany’s regional rail networks, the immediate question is timing. Delayed certification means delayed trains, and the longer deliveries slip, the greater the pressure on operators waiting for new rolling stock. For Alstom, the question is credibility: after two downgrades in seven months, investors will want evidence that the German programmes are back under control before they trust the next forecast.
