European Space Stocks Worth Watching After Isar Aerospace Reaches Orbit

Europe’s space ambitions just became more real. Isar Aerospace has reached orbit on its second test flight and reports a commercial pipeline above €10b, which underlines how much paying demand is forming around launch capacity. For investors, that kind of pressure on supply can reshape which stocks benefit from the new space race. This article reveals three stocks exposed to this news and explains why each could matter for your portfolio.

The three stocks below are just a starting sample. The full screen surfaced 31 more European aerospace and defense suppliers with space related profiles and equally compelling narratives that are not covered here. To identify and analyze your own highest conviction ideas in this theme, head straight to the European Aerospace & Defense Suppliers to Commercial Space screener.

OHB (XTRA:OHB)

Overview: OHB is a pure-play European space company that designs and builds satellites, space systems and related technology that go directly into orbital missions for navigation, communications, earth observation and security, giving investors one of the most direct listed exposures to demand for launch and satellite hardware in Europe.

Operations: OHB generates most of its revenue from the Space Systems segment at about €1.0b, with additional contributions from Access to Space at about €197 million and Digital at about €141 million, largely serving customers across the rest of Europe at about €805 million and Germany at about €406 million.

Market Cap: €3.8b

Investors looking for pure exposure to Europe’s commercial space build out may find OHB hard to ignore. The company sits across satellites, launch vehicle components and emerging ground infrastructure. Recent contracts such as the nearly €1.0b IRIS² MEO satellite deal and a €3.1b order backlog tie it closely to long term European space and defense programs. At the same time, a high P/E, modest current net margin and reliance on external borrowing mean expectations are already demanding and execution risk matters. With Germany discussing multi tens of billions of euros for space security and OHB involved in projects like Ariane 6 and Rocket Factory Augsburg, the stock gives direct exposure to this theme, but investors need conviction that growth and margins can catch up with the ambition.

OHB’s €3.1b backlog and exposure to IRIS² and Ariane 6 point to big expectations, yet the mix of a high P/E, modest margins and debt raises tough questions that the 4 key rewards and 1 important warning sign

Leonardo (BIT:LDO)

Overview: Leonardo is a large Italian aerospace and defense company that builds helicopters, military and civil aircraft, advanced electronics, cyber security systems, aerostructures, and a sizeable portfolio of space hardware such as satellites, avionics, sensors, and orbital subsystems, giving investors broad exposure to both traditional defense and the commercial space supply chain.

Operations: Leonardo generates most of its revenue from Defence Electronics & Security at about €9.1b and Helicopters at about €5.9b, with further contributions from Aeronautics at about €4.3b, Space at about €1.1b, Cyber & Security Solutions at about €859 million and Other Activities at about €732 million.

Market Cap: €29.2b

Leonardo provides exposure to European defense budgets and space activity in a single stock, with a meaningful €1.1b space business focused on satellites, electronics and subsystems that can participate as launch providers like Isar Aerospace generate more demand. The company is focusing on digital defense, AI and cyber security, while management has discussed using satellite constellations and space partnerships to build integrated air and missile defense solutions. At the same time, Aerostructures remains structurally weaker and the group relies heavily on external borrowing, so execution and capital discipline are important considerations. For investors who want exposure to a broad defense prime with space-related activities, Leonardo is a story that may merit closer examination rather than being watched from the sidelines.

Leonardo’s mix of defence electronics, helicopters and a €1.1b space business could be masking a different growth story. Get the full context from the analysis report for Leonardo

SGL Carbon (XTRA:SGL)

Overview: SGL Carbon is a German advanced materials company that produces graphite, carbon fiber and composite components used in high strength, lightweight and heat resistant parts for sectors such as aerospace, automotive, semiconductors and energy, which can include structures and thermal hardware for launch vehicles and satellites.

Operations: SGL Carbon generates most of its revenue from Graphite Solutions at about €459.6 million, with additional contributions from Process Technology at about €112.6 million and segment adjustments and corporate items totaling about €219 million.

Market Cap: €500 million

For investors tracking the commercial space build out, SGL Carbon supplies materials that are used in rocket nozzles, thermal shields and structural parts, and management has highlighted progress with customers in space and nuclear applications. At the same time, the company is working through Carbon Fiber restructuring, funding entirely through external borrowing and a history of losses. Forecasts point to a potential return to profitability and a share price below some cash flow estimates. If SGL Carbon achieves its confirmed 2026 guidance and maintains cost discipline, while deepening its role as a space materials supplier, the company may present a different profile to investors who are familiar with its past challenges.

SGL Carbon’s shift toward higher value space and nuclear materials could be masking a very different earnings profile. See how the latest guidance, margins and cash flows stack up in the analysis report for SGL Carbon.
