Vincorion IPO: German Defense Tech Lists on Frankfurt Stock Exchange | €850M Valuation

The initial public offering of Vincorion, a German supplier to the defense industry, was completed today, pricing shares at €17 each and valuing the company at €850 million. Trading begins on the Frankfurt Stock Exchange this Friday, marking a significant step for the Wedel-based manufacturer of energy and mechatronic solutions for military platforms and aerospace systems. The IPO comes at a time of increased defense spending globally, fueled in part by the war in Ukraine, and positions Vincorion to capitalize on what its leadership calls a “supercycle” in the defense industry.

A Strategic Shift for Star Capital

The listing represents a partial exit for Star Capital, a British investment firm that acquired Vincorion from Jenoptik in 2022 for €140 million. Handelsblatt reports that Star Capital initially sought a valuation exceeding €1 billion. Following the IPO, Star Capital’s stake will be reduced from 88.1% to 47.5%, though it will remain the largest shareholder. The offering saw significant interest from institutional investors, with Fidelity, Invesco, and T. Rowe Price collectively subscribing to €105 million worth of shares.

What Vincorion Makes – And Who Its Customers Are

Vincorion specializes in the production of critical components for defense applications, including generators for powering vehicles and air defense systems, heating systems for aircraft, and stabilizers for tanks. The company’s products are integrated into major defense platforms such as the Patriot and Iris-T air defense systems, and the Leopard tank. Deutsche Welle highlights the growing demand for these types of components, driven by increased geopolitical tensions and rising defense budgets across Europe. Key customers include Rheinmetall, KNDS, and other large defense contractors.

Financial Details and Market Positioning

In 2025, Vincorion reported revenue of €240 million, though profit figures were not disclosed. The company’s order backlog stood at approximately €1.1 billion at the finish of the year, providing a solid foundation for future growth. The IPO was managed by BNP Paribas, JP Morgan, and Berenberg. Vincorion’s CEO, Kajetan von Mentzingen, stated that the company is “strategically excellently positioned” to benefit from trends like electrification and increasing defense expenditures. He emphasized the company’s focus on developing and manufacturing reliable energy and mechatronic solutions for leading defense platforms and advanced aviation systems.

Insider Holdings and Management Continuity

Alongside Star Capital, key members of Vincorion’s management team as well retain significant stakes in the company. Finanzvorstand (CFO) Dieter Holst holds 3.6% of the shares, while Aufsichtsratschef (Chairman of the Supervisory Board) Tobias Seige owns 3.5%. This continued insider ownership suggests a long-term commitment to the company’s success. Kajetan von Mentzingen, the CEO who led the company through the IPO process, has been at the helm during a period of significant growth and increasing geopolitical uncertainty. Börsen-Zeitung notes that von Mentzingen has faced personal security challenges, including a suspected arson attack on his vehicle in June 2025, attributed to far-left extremists protesting the arms industry.

Implications for the German Defense Industry

Vincorion’s IPO is part of a broader trend of German defense companies seeking to capitalize on increased demand for military equipment. The German government has pledged to significantly increase defense spending in response to the war in Ukraine, creating opportunities for domestic suppliers like Vincorion. The listing in the Prime Standard segment of the Deutsche Börse provides Vincorion with access to capital markets, enabling it to invest in research and development, expand production capacity, and pursue strategic acquisitions. This influx of capital is crucial for maintaining Germany’s defense industrial base and reducing its reliance on foreign suppliers.

What’s Next for Vincorion

With trading set to commence on Friday, the focus will shift to Vincorion’s performance in the public market. Investors will be closely watching the company’s ability to execute on its growth strategy and deliver on its financial projections. The company’s management team will need to navigate a complex geopolitical landscape and manage supply chain risks to ensure continued success. Further details regarding Vincorion’s financial performance and future outlook are expected to be provided in its upcoming quarterly earnings reports. The company’s ability to maintain strong relationships with its key customers and adapt to evolving defense industry trends will be critical for long-term value creation.
