Alstom (ALO) Shares Plunge 28% on Second Guidance Cut

Alstom shares fell 28% after a second 2026 guidance cut, with Coradia Max delays dragging margin to about 1% and free cash flow to negative €1.5 billion.

The warning follows an April cut that sent the stock down about 30% shortly after Martin Sion took over as chief executive. Together the two events have cut the share price by more than half since January.

What Did Alstom Change in Its Guidance?

Alstom lowered every major financial target for the year to March 2027. The new figures are:

• Adjusted EBIT margin of about 1%, down from 6.5%.
• Organic sales growth of low- to mid-single digits, down from about 5%.
• Free cash flow of negative €1.5 billion, against a prior positive target.
• Car production of about 4,000 units, down from 4,400 to 4,500.

First-half results show the scale of the deterioration. Sales rose 3% to €9.3 billion, or 2% on an organic basis. The adjusted EBIT margin was about negative 4%, compared with 6.4% a year earlier. Free cash flow was negative €1.25 billion, and net debt rose to €1.1 billion at September 30 from €0.4 billion at the end of March. Orders reached €11 billion, up from €10.5 billion, and the book-to-bill ratio is expected to stay above 1 for the full year.

Why Are Coradia Max Delays Hitting Earnings So Hard?

Coradia Max delays are hitting earnings because problems found late in testing now carry costs across six German contracts. Alstom said the regional train platform faced industrialization challenges and longer homologation, the regulatory approval needed before trains enter commercial service. Production was paused in the first quarter to fix identified issues and limit retrofit work on trains already built. Car output in the half fell 8% to 1,860 units.

Deliveries that were expected next year are now pushed to 2028, which triggers contractual penalties. Because milestone payments depend on approvals and service entry, cash receipts slip into later fiscal years. The project now carries a negative gross margin, and Alstom is booking the expected loss on the whole program up front rather than spreading it over deliveries.

Sion said the review found weaknesses beyond engineering, describing project management around the program as neither efficient nor effective. He said the revised guidance reflects a risk-identification exercise intended to normalize group performance from the next fiscal year.

How Will Alstom Repair Its Balance Sheet?

Alstom plans to cut debt by about €2 billion, largely through asset sales, to protect its investment-grade credit rating. The chief financial officer said the assets have been identified and the sale process is starting, without naming them. The plan echoes the roughly €2 billion disposal program completed under the previous management during the 2023-24 balance sheet repair.

A negative €1.5 billion free cash flow on top of €1.1 billion of net debt leaves less room than in that earlier episode. Rating agencies and bondholders will watch both the pace of disposals and whether German milestone payments resume on schedule.

Market Reaction

The sell-off was among the sharpest in the European industrials sector this year. Shares fell as much as 30% in early trading before closing 28% lower. The first-half cash outflow and the reversal of the free cash flow target drew the most attention, as the market had priced in a margin shortfall but not a full-year cash burn of this size.

Alstom's order book remains large, with first-half orders up about 5% from a year earlier. That supports revenue visibility, but the 1% margin guidance implies little profit conversion from those orders in the current year.

Strategic Context

Alstom is the world's second-largest rail equipment group and builds the Luas fleet in Dublin, battery-electric trains for Ireland's DART expansion, and regional platforms across Germany. Its profitability depends on fixed-price, multi-year contracts, so engineering and homologation errors turn directly into penalties, retrofit costs and delayed cash. Management has scheduled a Capital Markets Day for the second quarter of 2027, where it is expected to set out medium-term targets after the program reset.

Outlook

Alstom has now reset its financial targets twice in seven months, leaving a 1% margin, a €1.5 billion cash outflow and net debt of €1.1 billion at the half-year point. The next tests are asset-sale announcements, the resumption of Coradia Max homologation and deliveries, and the Capital Markets Day in 2027. Management's stated aim is a return to normal performance from the 2027/28 fiscal year.
