OHB Shares Cool Off After Rally, but ESA Win and Rocket Launch Promise Next Moves

OHB shares fell 8.5% on profit-taking after rally. ESA picked Czech unit for €35M Earth-observation mission; RFA ONE launch in July.

OHB’s stock took a breather on Friday, sliding roughly 8.5% to close at €580 after a three-month surge that more than doubled the share price. Market participants chalked up the pullback to profit-taking rather than any single piece of bad news — the German space and defence group had run hard and fast, and a technical correction was widely anticipated.

The retreat came alongside two fresh developments that underscore OHB’s expanding footprint in both European defence and space exploration. On one front, the company’s Czech subsidiary, OHB Czechspace, beat out three rival bids to win selection by the European Space Agency for a new Earth-observation mission called SOVA-S. On another, Rocket Factory Augsburg — an OHB affiliate — has booked a launch window for the maiden flight of its RFA ONE rocket on 1 July from Scotland’s SaxaVord Spaceport.

ESA picked SOVA-S — short for Satellite Observation of Waves in the Atmosphere – Scout — after a ten-month review process. The mission, budgeted at under €35 million, will carry a shortwave infrared imager to measure gravity waves at altitudes between 80 and 120 kilometres by detecting airglow, a faint luminescence in the upper atmosphere. The data is intended to improve climate models, sharpen weather forecasts, and enhance GNSS positioning for aviation and other sectors. OHB Czechspace will serve as prime contractor, making SOVA-S the largest satellite ever built by the Czech Republic. The German Aerospace Centre (DLR) and other industrial partners are also involved.

A specific contract value has not been disclosed, so the near-term revenue impact remains unclear. Still, the selection signals OHB’s growing credibility in the European Earth-observation market. Analyst attention is likely to shift to whether the Scout award translates into a firm, funded contract in the coming quarters.

The ESA win follows another strategic move that has reshaped OHB’s narrative. In mid-May, the Bremen-based company announced a joint venture called KIRK with artificial-intelligence specialist Helsing. The partnership aims to build a space-based surveillance and target-acquisition system that combines satellites with AI — a direct play on rising defence budgets across Europe and a challenge to the dominance of US suppliers in the segment. Analysts view the venture as a potential catalyst for further order intake, even if near-term financial contributions are modest.

OHB’s operational foundation remains solid. In the first quarter of 2026, total operating performance climbed 15% year on year to €279.3 million, while adjusted EBITDA jumped 37%. The order backlog swelled to €3.354 billion, up from €2.314 billion a year earlier. The Space Systems segment accounted for €2.683 billion of that figure, underscoring the unit’s central role in the group’s growth.

The next major corporate event is the annual general meeting on 8 June. CEO Marco Fuchs has already ruled out a delisting, and shareholders will be looking for more detail on the group’s growth trajectory, including the development of the European Moonport Company. Outside the AGM, the market will also watch for pricing signals from the anticipated US listing of SpaceX around 12 June — a development that could recalibrate valuations for European space stocks and put OHB on the radar of global investors.

For now, the stock’s retreat has established €550 as the first support level. A break below that would bring the €500 mark into focus. Whether the RFA ONE test flight or ESA’s scout mission can reignite buying interest will depend on execution — and whether the broader rally in space stocks has further to run.
