Vincorion’s Order Book Swells to €1.2 Billion, but a Lock-Up Clock Ticks Louder

Defense supplier Vincorion's shares fell 4.3% in first post-IPO week despite 40% revenue surge and €1.2B backlog, as majority owner STAR Capital's lock-up until 2026 limits free float and creates selling pressure.

The stock of defense supplier Vincorion ended its first full week of post-IPO trading with a 4.3% decline, landing at €21.22 – despite a quarterly performance that would normally send shares soaring. The culprit isn’t the numbers, but the market structure around them.

STAR Capital, the majority owner with a 47.5% stake, remains locked up until autumn 2026. That constraint has kept the free float tight, amplifying both the rally that followed the March listing at €17 and the subsequent profit-taking. The shares are still up nearly 30% from the IPO price, but the rapid retreat from the highs highlights a vulnerability that has little to do with fundamentals.

And the fundamentals are, on the surface, stellar. In the first quarter, Vincorion’s revenue jumped 40% to €69.0 million, while adjusted EBIT rose 30% to €12.4 million. The adjusted margin, however, slipped to 18.0% from 19.4% a year earlier – landing right at the bottom end of the company’s full-year target range of 18% to 19%. The margin compression reflects the cost of rapid expansion: Vincorion is adding new assembly lines at its sites in Altenstadt, Essen and Wedel to process a swelling order book.

That backlog is the headline number. Order intake nearly quadrupled to €149.4 million, pushing the total order book to around €1.2 billion – covering more than 90% of the €280?million to €320?million in revenue the company expects for the full year. The Power Systems segment led the charge, with revenue climbing 42% to €20.7 million, driven by demand for ground-based air defense systems.

JPMorgan analyst David Perry argues the company is well positioned in the medium term, citing the massive backlog and ongoing capacity expansion. But the market is also watching the timeline for STAR Capital’s lock-up expiration. At a current market capitalisation of roughly €1.1 billion and limited free float, the potential release of a large block of shares could create persistent selling pressure – regardless of how the next quarterly results look.

Management reaffirmed its full-year guidance: revenue of €280?million to €320?million and an adjusted EBIT margin of 18% to 19%. Medium-term targets call for annual revenue growth above 15% and a margin of around 20%. Whether those goals are achievable depends on how smoothly Vincorion can ramp up production not only in Germany but also in the United States, where capacity expansion is under way.

Meanwhile, the company is deepening its strategic footprint in the defense sector through the EU-funded SENTINEL project, where it leads the German industrial role. The consortium involves 42 partners from 16 countries and carries a total project volume of nearly €40?million – a potential springboard for future NATO procurement contracts.

On the technical side, the stock’s relative strength index has fallen to 22.1, deep into oversold territory. That suggests the recent sell-off may be overdone, but with the lock-up overhang looming, a sustained recovery may depend on more than just good data. Investors will be watching the half-year results on 12 August for any signs that the order growth is translating into stronger cash flow – the next real test for the share price.
