Alstom's New CEO Tears Up the Playbook — and with It, the Market's Trust
PARIS, April 16, 2026 — Alstom SA dismantled the financial framework investors had been underwriting for nearly a year. In a preliminary release issued after the Board meeting today, the French rail champion disclosed that fiscal 2025/26 adjusted EBIT margin landed near 6%, below the ~7% previously guided, and that free cash flow came in at roughly €330 million — technically inside the €200–400 million range, but at the thin end of it. More consequentially, new Chief Executive Martin Sion, in his first major communication since taking office on April 1, formally withdrew the €1.5 billion three-year cumulative FCF target (FY 2024/25–FY 2026/27) and conceded that the group's 8–10% medium-term adjusted EBIT margin ambition will not be met by FY 2026/27. FY 2026/27 is now guided to ~5% organic sales growth and ~6.5% adjusted EBIT margin. Shares were reported sharply lower in after-hours reaction. Audited results are due May 13.
What Broke: Rolling Stock, Not Demand
The operational culprit is narrow in category but broad in reach: large rolling stock (railway vehicle) projects progressed more slowly than planned, compressing Q4 margins and tying up working capital. Production fell to 4,284 cars from 4,383, as programs lingered in ramp-up and homologation. The backdrop is well documented. Paris's MI20 trains for RER B have slipped such that first assembly is only targeted for April 2026 and service entry pushed toward end-2028; Île-de-France Mobilités imposed penalties. The TGV M / Avelia Horizon high-speed program remains schedule-sensitive ahead of a planned July 1, 2026 launch. Coradia Max deliveries to Germany have been postponed repeatedly. In Norway, Norske tog halted testing of Coradia Stream N05 trains in February after a bogie component failed laboratory validation. A French government-commissioned report in January 2026 blamed Alstom and SNCF for supply-chain fragility, over-specification, and slow approvals — delivery cycles now stretch eight to twelve years on some contracts.
Crucially, demand is not the problem. Orders hit a record €27.6 billion (book-to-bill 1.4), backlog cleared €100 billion, and sales rose to €19.2 billion (+7% organic). Europe's high-speed policy agenda and Germany's infrastructure spending remain supportive. The disconnect is between commercial intake and industrial conversion.
The Cash Number Was Good in the Least Reassuring Way
FCF of ~€330 million looks respectable until one reads the fine print. Alstom itself disclosed that customer downpayments from record orders and trade working-capital improvements offset headwinds from slower project progress. Cash held up because new business paid in, not because legacy problem contracts converted cleanly. That distinction explains why the three-year cumulative FCF target had to go: management is effectively conceding it cannot responsibly forecast the timing and quality of portfolio-level cash conversion. Liquidity is not the worry — net debt sits near €400 million against €2.3 billion of cash and €4.25 billion in undrawn facilities. This is an earnings-quality problem, not a solvency one.
The Backlog Deserves a Credibility Haircut
A €100 billion backlog is not €100 billion of risk-adjusted value. A year ago, Alstom highlighted backlog gross margin of 17.8% as evidence of improving future quality. Today's release notably did not refresh that disclosure. Until it does, the right stance is to discount the headline. Peer context is instructive but not exculpatory: Siemens Mobility delivered 8.8% margins with 8–10% guidance; CAF printed 5.5%, Stadler 4.4%. Alstom at ~6% is mediocre but survivable versus pure train-builders — yet deeply disappointing versus the services-and-signalling mix story Alstom sold investors.
The Deeper Question — and What to Ask Sion
The sharper diagnosis is not "execution." It is portfolio complexity: too many bespoke trains, across too many jurisdictions, on supply chains that cannot absorb the customization. Sion's aerospace pedigree (ArianeGroup, Safran) brings rigor, but aerospace discipline does not solve rail's political interfaces or homologation bottlenecks. He deserves credit for resetting expectations early; he does not yet deserve credit for fixing them.
The questions investors should press on May 13: How much FY 2025/26 cash came from downpayments versus milestone execution? What is current backlog gross margin? Are problem projects concentrated or systemic? What quantitatively bridges 6.0% to 6.5%? And what has changed in project-review governance that kept guidance intact as late as January — and in a preview note just a week before today's reset?
The honest stance: respect the franchise, distrust the algorithm.
