A&O Shearman advises on largest-ever defense IPO

A&O Shearman has advised the underwriting syndicate on the EUR3.8 billion initial public offering (IPO) of Czechoslovak Group (CSG) on Euronext Amsterdam, marking the world's largest defense IPO ever recorded, both in terms of amount raised and market capitalization. The transaction is also the largest European IPO since 2022 and the largest listing on Euronext Amsterdam in more than a decade.

The company offered 15.2% of its shares at a price of EUR25 per share. The transaction prices the company at roughly EUR25bn and is expected to generate about EUR3.8bn in gross proceeds. 

CSG is one of Europe's fastest growing defense companies and a critical long-term supplier to NATO states and partners. Based in Prague, Czech Republic, CSG operates across Europe, the United States and in other regions including Asia-Pacific. The Group continues to expand its global customer base, and it is currently serving more than 70 countries.

The underwriting syndicate was led by BNP Paribas, Jefferies, J.P. Morgan and UniCredit as joint global coordinators, with Česká spořitelna, Commerzbank, Deutsche Bank and Morgan Stanley acting as joint bookrunners.

The IPO attracted strong demand from leading global institutional investors, including cornerstone commitments of EUR900 million from Artisan Partners, certain funds and accounts under the management of BlackRock, and Al-Rayyan Holding LLC, a wholly owned subsidiary of Qatar Investment Authority.

The A&O Shearman multijurisdictional team was co-led by partners Jeff Hendrickson (U.S. capital markets, London), Petr Vybíral (finance and capital markets, Prague), and Michael Bloch (UK equity capital markets, London). They were supported by associate Denisa Jonášová (equity capital markets, Prague), senior associate Yolanda Borquaye (U.S. capital markets, London), associate Ezomime Onimiya (U.S. capital markets, London), senior associate Jack Mason-Jebb (UK equity capital markets, London), and senior associate Jort de Groodt (Amsterdam). Tax advice was provided by Amsterdam-based partner Rens Bondrager and Prague-based senior tax advisor Michal Dušek.

“This IPO highlights the strong international demand for CSG and the seamless coordination across jurisdictions required to deliver a transaction of this scale. We were pleased to support the banks and the company on a complex, cross‑border execution that brought together our U.S., UK and European ECM capabilities.”

“CSG’s immensely successful debut on Euronext Amsterdam marks an important moment for a Czech‑based leader in the defense sector and for capital markets not only in the region but Europe-wide. The listing further enhances CSG’s profile with international investors and positions the company very strongly for its next phase of growth and further development.”
