OHB SE: A Record Backlog Meets a Critical Regulatory Review

OHB SE faces regulatory scrutiny over a major defense contract, overshadowing strong operational results, record orders, and its role in NASA's Artemis II mission.

The successful splashdown of NASA’s historic Artemis II mission in the Pacific Ocean this week marked a major technological triumph for the European space contractor OHB SE. Yet, the Bremen-based company’s shares slipped below a key technical level, highlighting a stark contrast between its operational momentum and near-term market concerns over a massive defense contract.

At the heart of the recent share price weakness, which saw the stock fall to 262.00 euros, is an ongoing review by Germany’s Federal Cartel Office. The regulator is scrutinizing a planned joint venture between OHB and Rheinmetall Digital. The project under the microscope is the highly secure Bundeswehr communications network, SATCOMBw Stage 4, a program involving roughly 100 satellites with an estimated total value between eight and ten billion euros.

This regulatory uncertainty overshadows a period of exceptional operational performance. The company’s financial year 2025 was notably strong, with total output climbing approximately 21 percent to 1.25 billion euros. The adjusted operating result improved to 84.0 million euros, representing an EBIT margin of 6.7 percent.

OHB’s order book provides the most compelling evidence of its growth trajectory. It reached a record 3.19 billion euros at the end of 2025, supported by a book-to-bill ratio exceeding 1.5. A significant contributor was the EPS-Sterna contract signed in March, a 248-million-euro deal to build 20 small satellites for Arctic observation for EUMETSAT. This award, executed by subsidiary OHB Sweden, stands as the largest satellite contract in Sweden’s history.

The company’s strategic positioning has been further strengthened by the full acquisition of MT Aerospace AG at the end of 2025, making OHB the sole shareholder. This move solidifies its value chain for European launch systems like Ariane 6. The Artemis II mission itself showcased this capability, as the now-fully consolidated MT Aerospace supplied critical structural components for the mission's SLS heavy-lift rocket.

Looking ahead, management has set ambitious targets, aiming for revenue of 1.4 billion euros in 2026 and targeting the two-billion-euro mark by 2028. The company’s guidance also includes an EBITDA margin target of 11 percent for the current year. Investors will get their next fundamental checkpoint on May 7, 2026, when OHB releases its first-quarter results for 2026. The ordinary Annual General Meeting is scheduled for June 24, 2026.

The broader space sector tailwinds remain favorable, underscored by the European Space Agency’s record budget of 22.3 billion euros and Amazon’s firm booking of 18 Ariane 6 launches—a program from which OHB benefits directly through MT Aerospace. While the company has reaffirmed it has no plans for a delisting, the immediate share price direction now hinges heavily on the cartel office's verdict, creating a tense standoff between a powerhouse operational story and a pivotal regulatory decision.
