OHB’s Twin Catalysts: A Billion-Euro Share Sale and a Rocket Debut Converge in Late June

OHB SE faces pivotal week with KKR's stake sale expiration and RFA ONE debut, while forming new defense consortium KIRK and Rheinmetall JV.

For OHB SE, the coming days are about as concentrated as space-sector event calendars get. The Bremen-based aerospace company is staring down two separate, high-stakes deadlines that will shape both its shareholder base and its operational future: the expiration of KKR’s planned stake sale by June 30 and the maiden flight of its RFA ONE rocket on July 1. Either outcome — a successful exit for the private equity investor or a botched launch — would ripple through a stock that has already tripled this year.

New Alliances Forged at the ILA

All this unfolds against a backdrop of unusually brisk dealmaking. On the final day of the ILA Berlin air show, OHB gathered seven space start-ups under the KIRK consortium, a joint venture it shares with Helsing, Kongsberg Defence & Aerospace, and HENSOLDT. KIRK — an acronym for Künstliche Intelligenz und Raumfahrt-Kompetenz — marries satellite reconnaissance with AI-powered target recognition. OHB supplies the space systems and payloads; Helsing contributes real-time data processing.

The partners divide neatly: OHB teams with ConstellR, Rocket Factory Augsburg, and Marble Imaging, while Helsing pairs with DMI and TerraLens. LiveEO sits alongside OHB Digital and Helsing in a third grouping. The consortium has formalized its commitments in letters of intent signed June 12.

A Second JV Takes Shape

In parallel, OHB and Rheinmetall registered their joint venture “OHB Rheinmetall Space Networks GmbH” in the Bremen commercial register on June 11. The Bundeskartellamt cleared the deal in mid-April, and the new entity now formally exists to build encrypted satellite communications for Germany’s armed forces under SATCOMBw Phase 4. The venture covers everything from development and integration to operations and cybersecurity, linking soldiers, vehicles, and unmanned systems. Leadership is split between Dennis Winkelmann, a 19-year OHB veteran, and Alexander Beyer, a former Bundeswehr officer with deep satellite-communications expertise.

Beyond that joint venture, OHB is also competing for one of the Bundeswehr’s largest upcoming satellite contracts: the SPOCK 2 program, with an estimated volume of €5 billion. According to Handelsblatt, Airbus, Rheinmetall, and OHB are each leading separate consortia — an unusually fragmented bid process that has each prime contractor integrating German start-ups.

Asteroid Science Advances

On the scientific front, OHB Italia signed a contract with Dutch firm Cosine Remote Sensing at ILA to build the HAMLET hyperspectral camera for the ESA-JAXA RAMSES mission. The instrument will target asteroid Apophis as it swings within just 32,000 kilometers of Earth in April 2029, studying spectral changes on its surface.

Record Backlog and Ambitious Targets

All these projects rest on a solid financial foundation. In the first quarter of 2026, total output rose 15% to €279.3 million. Adjusted EBITDA jumped 37% to €27.3 million, while adjusted EBIT climbed 63% to €16.8 million. The order backlog hit a record €3.35 billion as of March 31, up 45% year-over-year.

Management’s medium-term guidance calls for total output of €1.7 billion in 2027 and over €2.0 billion in 2028, with an EBITDA margin target of 11%.

The Near-Term Squeeze

Despite the operational momentum, the stock’s trading dynamics remain extreme. At €409.00, OHB shares have gained 237% since January 1, but still trade roughly 40% below their 52-week high of €688.00. The culprit is a severe liquidity crunch: only about 5.7% of the 19.2 million shares are freely traded. That scarcity has driven 30-day annualized volatility to 148% — and the company says a recent dip was triggered by the sale of just 800 shares.

Private equity firm KKR holds around 29% of OHB and intends to sell roughly 20 percentage points of that stake at market, a package worth over €1 billion. The deadline is June 30. Should the placement succeed, free float could expand to about 26%, structurally calming the wild price swings.

A Rocket Roll of the Dice

The following day, July 1, marks the first launch window for OHB subsidiary Rocket Factory Augsburg’s RFA ONE rocket. Standing in the integration hall at the SaxaVord spaceport in Scotland, the rocket is set to carry seven small satellites. OHB itself is tempering expectations: fewer than 30% of maiden flights for new launch systems historically succeed, making failure statistically more likely than success.

A successful orbital debut would fundamentally reshape the small-satellite launch economics for OHB's portfolio. A failure, while painful, would not dent the record order book. Either way, the next two weeks will define the trajectory of a company that has already packed two years’ worth of news into a single spring.
