Vincorion’s EU Defence Role Gives Investors a Fresh Reason to Look Past the IPO Jitters

Vincorion shares climb above IPO levels as free float expands, US investors enter, and its role in EU defense project SENTINEL boosts outlook despite valuation discount.

The stabilisation net has been pulled, the free float has grown, and the shareholder register has been redrawn — yet Vincorion’s stock is trading higher than it did when the banks were still propping it up. The defence supplier’s post-IPO journey has taken a new turn, driven less by the mechanics of the flotation and more by the substance of its order book and a pivotal European defence project.

J.P. Morgan exercised the greenshoe option only partially, acquiring around 2.1 million shares. With that period now closed, Star Capital’s stake has fallen to 48.63%, stripping the private equity house of its absolute majority. The resulting increase in free float has already drawn in heavyweight US institutional investors: Fidelity, Invesco and T. Rowe Price each hold roughly 4% of the equity, according to the shareholder register.

The market has taken note. After touching a low of €15.32 in mid-April, the shares recovered to close the week at around €18, representing a double-digit percentage gain. The stock ended Friday’s session at €17.58.

A Central Role in Europe’s Energy Defence Blueprint

What has captured attention is Vincorion’s leadership position in Project SENTINEL, a nearly €40 million EU defence initiative now entering field testing. The company is supplying two core components — a power generator module and an energy storage system — that combine photovoltaic technology with fuel cells, designed to operate in extreme heat and dusty environments.

The first test campaign is underway with the Bundeswehr University in Munich, with international trials in different climate zones to follow. Crucially, Vincorion holds overall responsibility for energy storage within the project and coordinates 42 partner organisations. Analysts view this coordinating role as a strategic asset that could strengthen the company’s hand when bidding for future NATO contracts.

A Valuation Discount That Stands Out

Operationally, the company has been growing at an average rate of 22% over the past three years. Yet the valuation remains modest relative to domestic peers. The stock trades on a price-to-earnings multiple of around 46 based on 2025 earnings estimates. By contrast, Renk commands a P/E of 53, Hensoldt trades at 95, and Rheinmetall’s multiple exceeds 100.

That discount partly reflects the overhang from Star Capital’s remaining holding. The private equity firm still directly owns 47.5% of the shares, and the 180-day lock-up period expires in the autumn. Any sale of that tranche would materially increase supply and reshape the ownership structure once again.

Self-Funded Ambitions Meet the First Earnings Test

The IPO in March was a pure exit for Star Capital — no fresh capital flowed into the company’s coffers. Management must therefore finance its growth ambitions entirely from operating cash flow. The target for the current year is revenue of up to €320 million, underpinned by a backlog that has swelled to more than €1 billion.

A reassuring feature of the business model is the service segment, which accounts for more than half of sales. Maintenance and modernisation of existing military systems generate predictable income and above-average margins, often with Vincorion as the sole supplier.

On 7 May, the company will publish its first quarterly results as a listed entity. The numbers will need to demonstrate that rising European defence budgets are translating into firm orders. That earnings report arrives just as the autumn lock-up expiry looms — a double test that will determine whether the valuation gap to peers begins to close or widens further.
