Vincorion's 40% Revenue Surge and €153,000 Insider Buy Can't Escape Lock-Up Overhang

Defence supplier's Q1 revenue up 40% to €69M, order backlog record €1.2B, but nearly half shares locked up until 2026 causing extreme volatility and 15% weekly drop.

The defence supplier Vincorion is caught in a stark contradiction. Its first-quarter revenue jumped 40% to €69 million, the order book swelled to a record €1.2 billion, and a board member just put €153,000 of her own money into the stock. Yet the shares have lost over 15% in the past week, closing at €18.01 on Friday after a 2.4% decline that day. The culprit is not the business fundamentals but a structural bottleneck: nearly half the equity is locked up until autumn 2026.

Majority shareholder STAR Capital controls 47.5% of Vincorion's shares under a lock-up agreement that won't expire until the autumn of 2026. That leaves an extremely thin free float, amplifying every move. Positive news can send the stock soaring, but profit-taking hits just as hard. The volatility reading of 71% underscores the jittery mood, while the relative strength index has tumbled to 22, a territory that typically signals severe overselling.

The operational picture tells a different story. Revenue climbed 40% in the first quarter, and the order intake nearly quadrupled, pushing the total backlog to €1.2 billion. The operating margin eased slightly to 18%, but management still targets a full-year operating cash flow of €38 million — enough to fund the ongoing expansion of production capacity in Germany and the United States without external financing.

That expansion is already under way. Chief Executive Kajetan von Mentzingen has been hiring at a pace of roughly one new employee per month, aiming for annual workforce growth of 5% to 6%, a trend that has held since 2022. The company now employs more than 900 people, the majority at its headquarters in Wedel, Schleswig-Holstein. Vincorion's products — weapon stabilisation systems and generators for the Leopard 2 battle tank and Patriot missile systems — are in heavy demand as European governments pour money into defence. Germany's special €100 billion fund for the Bundeswehr is a particular driver.

The board's faith in the strategy was reinforced in March, when Maike Schuh acquired nearly 9,000 Vincorion shares at €17 each, for a total outlay of roughly €153,000. The insider purchase sent a clear signal of confidence from the leadership at a time when the market remains sceptical.

That scepticism may be tempered by the company's deepening involvement in NATO-focused research. Vincorion is a key participant in the SENTINEL project, a European Union initiative backed by nearly €40 million from the European Defence Fund. The programme is developing advanced mobile power supplies for field camps, designed to operate autonomously under extreme conditions. Success here could open the door to future NATO procurement contracts.

Yet for all the long-term promise, the near-term trading dynamics remain challenging. The stock peaked at €22.58 in early May — a level that now seems distant. The lock-up structure means that any rally runs into selling pressure from those looking to take profits before the shares become more freely tradable. When the lock-up does expire in 2026, the unloading of a large block could hit the market hard.

The next major test comes on 12 August, when Vincorion reports its half-year results. Investors will be watching the free cash flow particularly closely: in the first quarter it was negative, and a positive swing in the summer would go a long way toward validating the growth story. Until then, the shares are caught between a booming order book and the lock-up shadow that keeps a lid on sentiment.
