Vincorion’s Free Float Swells as Greenshoe Expiry Reshapes the Shareholder Register

The safety net has been pulled from under Vincorion’s stock, and the shares are rising anyway. The mechatronics and defence supplier has entered a new phase of its public life, one where the market alone decides the price and the ownership structure looks markedly different from the day of its IPO.

STAR Capital, the private equity firm that controlled Vincorion ahead of its stock market debut, has seen its stake drop to 48.63 percent, according to a voting rights disclosure filed on 24 April. That is down from just under 53 percent and marks the first time the majority owner has fallen below the psychologically important 50-percent threshold. The reduction is a direct consequence of the expiry of the Greenshoe option, the price-stabilisation mechanism that had been in place since the March listing.

With the banks no longer buying shares to prop up the price, the effective free float has increased. That shift matters because many institutional investors have minimum free-float requirements before they can take a position. Fidelity International, Invesco and T. Rowe Price are already estimated to hold just under four percent each, and the expanded public float now gives them room to build their stakes further through regular market purchases.

The stock closed at €17.58 on Friday, comfortably above the issue price and well off the low of €15.32 it touched earlier in its trading history. In the week that the Greenshoe expired, the shares actually gained nearly twelve percent, suggesting that the market is looking past the technical mechanics of the IPO and focusing on the underlying business.

Should investors sell immediately? Or is it worth buying VINCORION?

That business is heavily weighted toward aftermarket services, which account for 55 percent of revenue. Vincorion specialises in upgrading and maintaining existing military platforms, a model that generates predictable income through long-term service contracts and delivers above-average margins. The company is the sole supplier of certain components for the Leopard 2 battle tank and the Puma infantry fighting vehicle, and it holds a similarly entrenched position with the PATRIOT air-defence system under a long-term framework agreement with NATO’s procurement agency.

The order book stands at over €1 billion, and the challenge for management is converting that backlog into revenue growth. For the full year 2026, the board is targeting sales of up to €320 million. The company funds its expansion entirely from internal cash flow, which reached €38 million in operating cash flow, and has grown at an average annual rate of 22 percent over the past three years.

Despite that track record, the valuation remains relatively modest by defence-sector standards. Vincorion trades at a forward price-to-earnings multiple of 46 for the coming year. That compares with 53 for rival RENK and multiples above 90 for HENSOLDT and Rheinmetall.

The next major test arrives on 7 May, when Vincorion publishes its first quarterly report as a listed company. Investors will be watching to see how quickly the order backlog translates into reported revenue and whether the European defence spending boom is translating into hard contracts. A lock-up agreement prevents STAR Capital from selling additional shares until the autumn, which means the market can focus on operating performance rather than overhang risk for the next several months.
