CSG's €58 Billion Contract and Short-Seller Attack Leave Investors Scrambling for Clarity

Czechoslovak Group’s stock crashes over 50% in 2025 as Hunterbrook Capital challenges its business model and a €58B EU-backed contract faces partner delays, despite strong revenue growth.

The Czechoslovak Group (CSG) is facing a crisis of confidence that its powerful operational metrics have so far failed to defuse. The defence and engineering company’s Amsterdam-listed shares have shed more than half their value since January, closing at €15.98 on Friday — a 53% plunge from the year’s high of €33.81 and a 36% loss over the past month alone. At the heart of the sell?off lie two separate but overlapping pressure points: a damaging short?seller report and growing uncertainty over a record EU?backed contract.

Short?Seller Allegations Spur Freefall

The immediate trigger for the latest leg of the rout came last Monday, when Hunterbrook Capital published a report challenging CSG’s core business model. The activist short seller claimed that the majority of the group’s ammunition sales come from brokering and refurbishing old stock rather than from own production. CSG’s shares cratered by 13% on the day.

Management swiftly rejected the allegations as “selective” and “distorted”, pointing to public data. The company stated it produced approximately 630,000 rounds in 2025 and plans to expand in?house manufacturing by roughly 20% this year. A new production line in Slovakia is expected to deliver additional capacity. CSG also dismissed suggestions of hidden liabilities, noting that an outstanding receivable of €275 million from the sale of non?core assets ahead of its initial public offering had been fully settled in the first quarter, exactly per the timetable laid out in the prospectus.

A €58 Billion Framework with a Tight Deadline

While the short?seller controversy dominates headlines, a larger structural risk is brewing in Bratislava. CSG’s joint venture ZVS Holding — controlled by the Slovak state and the CSG Group — signed a framework agreement with Slovakia’s defence ministry to supply artillery and tank ammunition. The maximum value is €58 billion over seven years.

The contract is designed to leverage the EU’s SAFE programme, which offers member states financing at an interest rate of just 1% with maturities of up to 40 years. However, the special terms only apply if at least two EU countries participate in the agreement. That condition must be met by the end of May 2026.

Efforts to secure a second partner have so far stalled. Romania’s defence ministry denied any ministerial?level discussions. Croatia is weighing participation but has not committed. The Czech Republic, CSG’s home market, has ruled out involvement, with officials citing concerns that the deal resembles a single?tender procedure. CSG has played down the urgency, insisting the framework is a ceiling rather than a binding order volume, and that the business does not rely on a single EU funding mechanism.

Operational Strengths That the Market Is Ignoring

The market’s scepticism stands in sharp contrast to CSG’s financial performance. Revenue surged to €6.7 billion in 2025, and management is guiding for €7.4 billion to €7.6 billion this year with an EBIT margin of 24?25%. The company’s order backlog stands at €42 billion.

Last month, Moody’s upgraded CSG’s credit rating from Ba1 to Baa3, granting it investment?grade status for the first time. Fitch also affirmed its BBB?minus rating with a stable outlook. The upgrades lower financing costs and broaden the potential investor base to institutions with minimum?rating mandates.

Alongside the balance?sheet progress, CSG is expanding its footprint. It recently agreed to acquire 49% of Hirtenberger Defence Systems from Hungary’s 4iG Group — its first move into Austria, strengthening its mortar?ammunition portfolio. A separate partnership with Polish state?owned PGZ targets propulsion systems for unmanned platforms.

The May 20 Reckoning

The next major catalyst is 20 May 2026, when CSG will publish its first?quarter results. The report will include one?off costs related to the IPO, offering an early test of how resilient the group’s margins really are. Equally important, it will provide concrete data on order conversion, cash flow, and the actual progress of production expansion — the very areas the short sellers have put under scrutiny.

Analysts remain broadly bullish. Nine analysts rate the stock a buy, with a consensus price target of €35.40 — more than double the current level. Whether their confidence is justified should become clearer in the final days of May, once both the Q1 numbers and the fate of the SAFE contract deadline are known. For now, CSG is a study in contradiction: a company with investment?grade credit, double?digit growth, and a €130 billion pipeline, yet a stock that investors cannot seem to trust.
