Alstom Stock In Focus As Channel Tunnel Rail Competition Opens Up

Simply Wall St·08/17/2026 16:31:07
Listen to the news

Competition is finally coming for Eurostar’s Channel Tunnel monopoly, with Virgin cleared for future high speed services and eyeing new Alstom trains. That kind of regulatory shift can reshape demand for rail equipment and infrastructure, which matters if you care where long term capital flows next. This article walks through 3 stocks that appear closely linked to this news so you can judge which exposures might fit your portfolio.

The stocks covered below are just a starting sample, and the full screen surfaced 41 more companies with similarly interesting rail and rolling stock stories that are not covered here. If you want to identify potential opportunities quickly, head straight into the European Rail Infrastructure & Rolling-Stock Manufacturers screener.

Nexans (ENXTPA:NEX)

Nexans is an electrification focused cable group that supplies power and data cables, along with related engineering and lifecycle services, to utilities, buildings, offshore wind, subsea interconnections and industrial customers. The bulk of its €8.6b revenue comes from PWR Grid & Connect at about €5.5b, with PWR Connect alone contributing around €3.8b and PWR Grid about €1.7b, while PWR Transmission adds roughly €1.8b and Other Activities around €1.3b. Nexans currently has a market cap of about €6.1b.

Investors looking at the Channel Tunnel opening to new operators may find Nexans interesting because it already leans into electrification, high voltage projects and grid upgrades that underpin more intensive cross border rail use. The company is growing earnings quickly, has been lifting guidance and is investing to expand European PWR Grid capacity, yet the stock still trades below some estimates of fair value. The flip side is a relatively high P/E, recent one off losses and an inexperienced management team, which leave little room for error if project execution stumbles or demand softens. The real question is whether Nexans can turn tight grid capacity and strong order pipelines into sustained, higher quality cash flows as this rail and energy build out gathers pace.

Nexans’ accelerating earnings story and grid expansion plans can look compelling, yet the high P/E and recent one off losses raise hard questions about risk. Get the full picture in the 4 key rewards and 2 important warning signs

Prysmian (BIT:PRY)

Prysmian is a global supplier of power and telecom cables that sit at the heart of electrification and data connectivity, from high voltage transmission lines to fiber running into data centers. It generates most of its revenue from Electrification Industrial & Construction at about €8.3b, with a further €4.2b from Power Grid, €3.4b from Transmission, €3.0b from Electrification Specialties, €1.9b from Digital Solutions and around €0.6b from other electrification products. The company is large, with a market cap of roughly €37.4b.

Investors looking at European rail infrastructure and the Channel Tunnel story may find Prysmian interesting because every extra train service eventually needs more power and signaling cable, as well as the fiber that carries traffic information and ticketing data. The company is already tied into multi year capex around grids and data centers, with high single digit revenue growth forecasts, earnings growth projected in the mid teens and earnings quality described as strong. That upside sits alongside real risks, including high debt, share price volatility and the pressure to keep delivering after recent upgrades to guidance. The open question is whether Prysmian can keep turning this mix of grid, AI data center and transport related demand into resilient cash generation without tripping on project or balance sheet risks.

Prysmian’s mix of grid, AI data center and transport projects hints at a powerful growth story, yet high debt and volatility still hang over the equity case. Get the full analyst forecasts for Prysmian and see what the consensus might be missing

Alstom (ENXTPA:ALO)

Alstom is a pure rail transport specialist that designs and supplies everything from high speed trains and metros to signaling systems and long term maintenance services for operators worldwide. The group generates all of its roughly €19.2b revenue from its Transport segment, which bundles rolling stock, signaling, services and turnkey systems across France, wider Europe, the Americas, Asia Pacific and Africa. Alstom currently has a market cap of about €7.5b.

The Channel Tunnel opening up to Virgin and other operators puts Alstom directly in the spotlight, since Virgin is already eyeing 12 new high speed trains and regulators appear more open to cross border services that need exactly the rolling stock and signaling Alstom supplies. The company sits on a large contract pipeline and has been focusing on higher quality work in Services and Signaling. This supports the idea of better margins over time, even if current net profit margins are still thin at 1.5% and legacy contracts weigh on returns. Earnings growth forecasts above 20% a year, combined with fresh wins from Australia to Egypt and an improving balance sheet, give the story real appeal. However, supply chain stresses, funding entirely from external debt and an AMF investigation into financial communications mean this is not a simple growth stock. Investors who want pure rail exposure with direct leverage to Channel Tunnel capacity have plenty to weigh up before deciding whether Alstom’s rebuilding story is strong enough for their risk tolerance.

Alstom’s accelerating order book and thin 1.5% net margins point to a story that could still be early. Tap into the analyst forecasts for Alstom and see how the contract pipeline might change the ending.
