Alstom Shares Plunge 30 Percent After Outlook Cut Over Coradia Max Delays

Alstom shares plunged 30 percent in early trading in Paris on Monday after the French train maker cut its full-year outlook for a second time in 2026, blaming execution problems on major projects in Germany.

The company said problems on the Coradia Max programme, a series of regional trains ordered by German states, had driven half-year profitability sharply lower and hit cash flow. Technical issues and additional testing requirements extended the certification timeline for the trains, delaying deliveries to customers.

Margins and cash turn negative

Alstom said its adjusted core profit margin was around minus 4 percent in the first half of the financial year, compared with plus 6.4 percent a year ago. It lowered its full-year margin forecast to around 1 percent, from an earlier forecast of 6.5 percent.

The cash outlook changed just as sharply. Alstom cut its free cash flow target for the year to an outflow of 1.5 billion euros, or 1.7 billion dollars, having previously guided for a positive result. Alongside the new forecast, the company launched a plan to reduce debt by around 2 billion euros.

Citi analysts estimated that the negative cash flow forecast was equivalent to roughly 20 percent of Alstom market capitalisation, Reuters reported. Including the Monday drop, the stock has lost 54 percent of its value in 2026. The Wall Street Journal reported that the shares traded down 29 percent at 11.18 euros in its report, and put first-half order intake at 11 billion euros and sales at 9.3 billion euros.

One programme at the centre

The setback centred on the Coradia Max. Alstom said the technical issues and the extra testing required on the programme extended certification, delayed deliveries, and also led to additional work and schedule overruns on some projects.

Alstom cut its annual production target to around 4,000 rail cars, from a range of 4,400 to 4,500 previously. It now sees low to mid single digit percent organic sales growth, against a previous forecast of around 5 percent.

Chief executive Martin Sion said in a statement reported by The Wall Street Journal: "Since my appointment as CEO in April 2026, I have requested rigorous identification and escalation of project-level risks and opportunities."

A second cut in one year

Reuters reported that this warning came less than seven months after Alstom scrapped a three-year free cash flow target and cut its margin outlook. Monday was therefore the second time in 2026 that the company told investors to expect less.

The wider European market moved little by comparison. Reuters reported that the pan-European STOXX 600 index slipped 0.3 percent to 645.04 points by 0813 GMT on Monday, in a market report that had Alstom down 27 percent at that earlier time of day.

For Alstom, the task is now plain. It must certify and deliver the delayed Coradia Max trains, restore a positive margin, and cut debt while investors wait for proof that project risks have been found early rather than late.
