OHB’s Volatility Spike: How a Blocked €1 Billion Deal and a Tiny Free Float Sent Shares on a Rollercoaster

OHB SE shares plunged 26% in a week after a €1B block trade was pulled, highlighting extreme volatility in thinly traded stock despite record orders and strong Q1 results.

The past week at OHB SE has been a masterclass in how thin liquidity and a single corporate setback can turn a fundamentally sound business into a day-trader’s nightmare. Shares in the German space and defence group suffered two savage hits – a 16% plunge on 27 May after a large placement was pulled, followed by a further 10% wipeout two days later in a session driven almost entirely by market mechanics rather than any fresh news.

For a stock that has soared from a 52-week low of €64.00 to a high of €662.00, such wild swings are becoming the norm. The Friday collapse in particular highlighted the precarious nature of a market where just 1,019 shares changed hands on the Stuttgart exchange. A price range of €421.50 to €478.50 – a spread of nearly €57 – showed how a handful of orders can derail the entire tape.

The placement that wasn’t

The catalyst for Wednesday’s rout was the abrupt suspension of a planned block trade that, according to market sources, was set to shift more than €1 billion worth of stock – roughly 20% of the company’s equity. The deal would have reshaped OHB’s ownership structure: existing shareholders KKR, with its 29% stake, and the Fuchs family, which controls 65%, were expected to participate. KKR was likely to have sold down its position, while the Fuchs family would have seen its holding diluted by a new share issuance.

The banking syndicate had already been beefed up. Berenberg and Commerzbank were joined by Jefferies and UniCredit, alongside Deutsche Bank, Goldman Sachs and JPMorgan. Yet the transaction never made it across the line, leaving investors to wonder whether OHB’s capital needs will now be met through alternative channels.

That question will dominate the company’s virtual annual general meeting on 8 June. On the agenda is a dividend of €0.60 per share – a total payout of roughly €11.5 million – but far more important are the authorisation requests. OHB is seeking approval to issue convertible and warrant bonds worth up to €1.2 billion, valid until June 2031, along with contingent capital of up to €3.84 million (20% of current share capital). A separate pot of up to 576,447 shares is reserved exclusively for executive and employee stock options, capped at 3.0% of the share capital.

Financial strength, structural weakness

None of the recent volatility stems from a deterioration in the operating business. On the contrary, OHB’s first-quarter numbers, released on 7 May, showed total output rising 15% year-on-year to €279.3 million. Adjusted EBITDA jumped 37% to €27.3 million, while net profit more than doubled to €9.9 million from €3.7 million a year earlier.

The order book tells an even more compelling story. At the end of March, the backlog stood at a record €3.35 billion, up 45% versus the prior year. The Space Systems segment alone accounted for €2.68 billion, buoyed by ESA programmes and rising European defence budgets. Management’s medium-term targets are ambitious: total output of €1.4 billion in 2026, €1.7 billion in 2027, and over €2.0 billion by 2028, with an EBITDA margin of 11%.

Yet this robust operational picture sits uneasily alongside a capital market structure that is anything but healthy. Only 5.68% of the 19.15 million shares are in free float. That means any institutional buying or selling, let alone a derailed placement, can produce outsized price moves. The seven-day chart shows a decline of roughly 25%, even as the monthly chart still boasts a gain of around 79%. The discrepancy is a pure function of trading mechanics, not fundamental change.

Next catalysts: the rocket and the AGM

Immediately after the AGM, OHB will face a high-stakes operational test. Its subsidiary Rocket Factory Augsburg has applied for a launch window starting 1 July for the maiden flight of the RFA ONE rocket. The first two stages have already been delivered to SaxaVord in Scotland. A successful test would open the door to commercial launches, with RFA targeting up to 25 missions per year once series production begins in 2028.

OHB itself cautions that fewer than 30% of first flights of new launch systems succeed historically. The event is therefore both a catalyst and a risk. Should the rocket fail, the market may question the timeline for this new growth path, which sits alongside OHB’s core satellite and space infrastructure business.

For now, the company is left navigating a market that reacts to every order flow. The next three dates to watch are the 8 June AGM, the RFA ONE launch window from 1 July, and the second-quarter results on 6 August. Each offers a chance to refocus attention from a turbulent share price back to a business that, on the numbers, is firing on all cylinders.
