Hunterbrook: Europe's Biggest Defense IPO Omitted a NATO Factory Suspension, a €1.4B Minority Buyout Demand, and Evidence That 80% of Ammunition Revenue Comes From Sourcing, Not Manufacturing

CSG raised €3.8B at a €25B valuation selling a modern ammunition manufacturer story — but subsidiary filings suggest only ~€524M of its €2.5B in 2024 ammo revenue can be explained by its own factories, with the rest sourced externally or recommissioned

9 min read

The prospectus omissions are the sharpest part of the case. FMG, CSG's Spanish propellant factory described as central to its vertical integration strategy, was suspended by NATO's procurement agency in July 2025 – six months before the IPO – with a NATO official telling Hunterbrook the suspension involved contractors "suspected in fraudulent and corrupt activities related to NATO contracts." Minority shareholder Petr Kratochvíl exercised a €1.4 billion put option on January 20, the week of the IPO; the prospectus did not disclose it. The €58 billion Slovak framework deal announced weeks before listing represents "maximum potential value, not committed orders" per CSG itself, and none of the eight countries named as participants confirmed they would join. On the financial side, CSG reported €1.6 billion in operating EBIT but only €61 million in operating cash flow – a 3.8% conversion rate versus Rheinmetall's 66% – while net debt nearly doubled to €3 billion and working capital rose from 13% to 24% of revenue. CEO Michal Strnad sold €2.55 billion of stock in the IPO.

Position Disclosure: Hunterbrook discloses that it holds a short position in CSG and will therefore benefit financially if the share price declines.


Thesis

Hunterbrook alleges that CSG's post-IPO growth story as a leading European ammunition manufacturer is materially overstated, and that the company's prospectus omitted several risks that were known or knowable at the time of listing.

  • Flagship Deal, No Buyers: The €58 billion Slovak ammunition framework agreement — announced weeks before the IPO — was a framework contract, not firm orders. CSG itself told Hunterbrook it represents "maximum potential value, not committed orders." Reporting by ICJK found none of the eight countries Slovak Defense Minister Kaliňák said would join had confirmed participation; the Netherlands said the deal was "not currently relevant" and the Czech Republic reportedly blocked consideration, viewing it as akin to a no-bid contract.
  • Manufacturing Footprint Overstated: The prospectus lists 14 ammunition factories on one page and 12 on another; the 2025 annual report sustainability section references only seven operating entities involved in ammunition manufacturing, of which only four appear to make finished medium- or large-caliber ammunition. Dubnica nad Váhom appears to be the only facility publicly described as capable of producing fully assembled 155 mm rounds, with estimated 2025 output around 100,000 rounds — far below what the prospectus math implies.
  • Revenue Mostly Sourced, Not Made: Hunterbrook's analysis of 2024 subsidiary filings in Czech, Slovak, and Spanish registries estimates that the four main ammunition factories generated no more than roughly €409 million in net in-house production revenue. Applying the Defence Systems division's estimated 28% EBIT margin yields approximately €524 million of revenue attributable to CSG's own factories — against CSG's reported €2.5 billion in 2024 medium- and large-caliber ammunition revenue. The prospectus acknowledges one production method is "recommissioning" of expired or lower-quality ammunition sourced externally.
  • Recommissioning Supply Is Finite: That recommissioning model depends on dwindling external stocks. A 2024 Reuters investigation, citing a senior Czech official, estimated available global large-caliber ammunition stocks at 2 million rounds. A 2024 research study cited in the report suggested those stocks would not last more than a couple of years. Supply constraints from the U.S., South Korea, and India are also cited.
  • Production Ramp Requires Capital CSG May Not Have: CSG reported €1.6 billion in 2025 operating EBIT but only €61 million in operating cash flow — a 3.8% conversion rate. Working capital reached €1.6 billion, rising from 13% to 24% of revenue year-on-year. Net debt stood at €3 billion, nearly double the prior year and nearly twice operating profit. CSG is guiding to €638 million in capex. Rheinmetall, by comparison, reported 66% cash conversion in 2025.
  • NATO-Suspended Factory, Undisclosed: FMG, CSG's Spanish propellant factory and a pillar of its vertical-integration strategy, was suspended by NATO's procurement agency NSPA from bidding for new contracts in July 2025 — six months before the IPO. The suspension was extended indefinitely as of March 2026. A NATO official told Hunterbrook that NSPA would not comment on proceedings involving "contractors suspected in fraudulent and corrupt activities related to NATO contracts." CSG called the suspension procedural and immaterial.
  • Undisclosed Put Option: The report alleges that minority shareholder Petr Kratochvíl exercised a put option on January 20, 2026 — days before the IPO — demanding €1.4 billion for his 10% stake in CSG Land Systems. The prospectus did not disclose this. CSG told Hunterbrook that outside counsel concluded the option was not effectively exercised before the IPO and that auditors found no liability requiring disclosure. Kratochvíl's Class B shares carry four votes each and confer veto rights over major capital and structural decisions.
  • Related-Party Cash Movement: The 2025 annual report shows €275 million in related-party receivables owed from Ytara SPV — a vehicle personally owned by CEO Michal Strnad — arising from pre-IPO disposal of subsidiaries. Those disposals involved €63.3 million of cash leaving the group and negative cash proceeds of €56.9 million. Former CSG vice-chairman Miroslav Dorňák, who left in 2022, acquired the building into which CSG subsequently moved its headquarters; CSG now pays him rent.
  • Political and Governance History: The report alleges a decades-long pattern of growth aided by political connections, including campaign financing tied to former President Miloš Zeman, government contracts awarded without competitive tender, and acquisitions described by Czech media as irregularly priced. CSG's key propellant supplier FMG and an associated executive face ongoing criminal proceedings in Slovakia. In 2024, CSG hired former Interior Minister Jan Hamáček — previously investigated over an alleged plan to trade Czech silence on the 2014 Vrbětice ammunition depot explosions for political concessions — as director of external relations.
  • Russian-Linked Investor History: Foreign Policy reported in 2018 that one of Jaroslav Strnad's key investors was Alexei Belyaev, described as connected to sanctioned Putin associate Vladimir Yakunin. A WikiLeaks-published U.S. Embassy cable identified co-investor Michal Lazar as suspected of organized-crime connections. Multiple Republican senators including JD Vance wrote to Treasury Secretary Janet Yellen in January 2024 urging denial of CSG's CFIUS application, citing ties to Putin's inner circle. CFIUS approved the deal.

Notable Details

  • Michal Strnad, 33, sold €2.55 billion of stock in the IPO and became the richest person in the Czech Republic. CSG's revenue had grown from roughly €580 million before the Ukraine invasion to €6.74 billion in four years.
  • Seznam Zprávy reported that CSG's March 2026 annual report initially contained language disclosing the January 20 date of Kratochvíl's put-option notice, then deleted it. The outlet said it found the removed text in "invisible ink" in the document; CSG attributed the deletion to a software glitch.
  • Rheinmetall spent nearly €500 million on a single greenfield German ammunition plant expected to produce 350,000 155 mm shells per year by 2027, and its 2025 capex was nearly four times CSG's. CSG compares its 1.1 million round target to Rheinmetall's 1.1 million — but Rheinmetall's figure refers specifically to 155 mm shells, while CSG's covers medium- and large-caliber combined; Rheinmetall's total rounds target including other calibers is approximately 4.5 million.
  • Handelsblatt reported that shells supplied through the Czech ammunition initiative — some apparently from Excalibur Army — malfunctioned in Ukraine, with five out of every 10,000 fired exploding prematurely due to outdated World War II-era detonators. Michal Strnad told the Financial Times in May 2024 that roughly half the components his company was buying from suppliers in Africa and Asia were not of sufficient quality to ship directly to Ukraine.
  • Radio Free Europe/Radio Liberty's Schemes obtained documents showing Excalibur Army offered 155 mm shells to the Czech government in February 2024 at €3,200 per unit while a Turkish manufacturer offered seemingly comparable shells to Excalibur Army for €2,500 each — implying roughly a 30% markup at one step in the chain. Investigative journalists separately reported that Czech intermediaries charged margins at least four times higher than Ukrainian arms brokers for comparable procurement.

"CSG appears to resemble the Cold War inventory-liquidation business it once was, with a manufacturing side business that seems much smaller than implied."

FAQs

What is the €58 billion Slovak ammunition deal, and why does Hunterbrook question it?

In December 2025, Slovakia's defense ministry signed a framework agreement with ZVS Holding — a 50/50 joint venture between CSG and the Slovak government — with a stated maximum value of up to €58 billion over seven years. Slovak Defense Minister Robert Kaliňák said eight countries would join. Reporting by ICJK found that none of the named countries confirmed plans to participate; the Netherlands said the deal was "not currently relevant" and the Czech Republic reportedly blocked consideration as akin to a no-bid contract. CSG itself told Hunterbrook the figure represents "maximum potential value, not committed orders."

How does Hunterbrook calculate that most of CSG's ammunition revenue comes from outside sourcing?

Hunterbrook reviewed 2024 subsidiary filings in Czech, Slovak, and Spanish registries for CSG's main ammunition factories — ZVS, VOP Nováky, ZVI, and FMG — and estimated their combined net in-house production revenue at no more than €409 million. Applying the Defence Systems division's estimated 28% EBIT margin, it derived approximately €524 million of total revenue attributable to CSG's own factories. CSG reported €2.5 billion in medium- and large-caliber ammunition revenue for 2024, leaving roughly 80% unaccounted for by manufacturing. CSG's own prospectus acknowledges that one production method is "recommissioning" of expired or lower-quality ammunition sourced from NATO armies.

What is the FMG NATO suspension, and why does it matter?

FMG — Fábrica de Municiones de Granada — is CSG's Spanish ammunition factory, which the prospectus describes as important to its vertical integration strategy, particularly for propellant charges used in 155 mm ammunition. In July 2025, six months before the IPO, NATO's Support and Procurement Agency (NSPA) suspended FMG from bidding for new contracts. The suspension was reportedly extended indefinitely as of March 2026. A NATO official told Hunterbrook that NSPA would not comment on proceedings involving "contractors suspected in fraudulent and corrupt activities related to NATO contracts." CSG called the suspension procedural, said it was related to an internal NSPA matter rather than FMG wrongdoing, and characterized it as immaterial because FMG can still sell to member states directly.

Who is Petr Kratochvíl, and what is the put-option dispute?

Petr Kratochvíl ran Excalibur Army from 2005 to 2024 and holds a 10% stake in CSG Land Systems, the entity above Excalibur Army. His Class B shares carry four votes each and confer rights to appoint board members and veto major capital and structural decisions. Seznam Zprávy reported that Kratochvíl exercised a put option on January 20, 2026 — the week of the IPO — demanding €1.4 billion for his stake. The prospectus did not disclose this. CSG told Hunterbrook that outside counsel concluded the option was not effectively exercised before the IPO and that auditors found no liability or contingent liability requiring disclosure. Kratochvíl told Seznam Zprávy he had been promised there would be no IPO.

What is the Ytara SPV, and why does Hunterbrook flag it?

Ytara SPV is a vehicle personally owned by CSG CEO Michal Strnad. Ahead of the IPO, roughly two dozen CSG subsidiaries were carved out and transferred to Ytara. The 2025 annual report shows €275 million in related-party receivables owed from Ytara to CSG arising from those disposals, alongside €63.3 million of cash that left the group and negative cash proceeds of €56.9 million on the transactions. Hunterbrook describes the structure as one where the CEO personally owns a vehicle that received assets from the listed company and sits above it in the corporate chain, while the company awaits repayment of a large receivable. CSG said the carved-out entities were non-core and that the receivable would be settled in cash.

How does CSG's cash generation compare to its stated ambitions?

CSG reported €1.6 billion in 2025 operating EBIT but only €61 million in operating cash flow, a 3.8% conversion rate. Working capital rose from 13% to 24% of revenue year-on-year, reaching €1.6 billion. Net debt stood at €3 billion at year-end, nearly double the prior year and nearly twice operating profit. CSG is guiding to €638 million in capex. For comparison, Rheinmetall reported 66% cash conversion in 2025 and guided to at least 40% in 2026. Hunterbrook argues the gap between CSG's earnings and cash generation raises questions about how it will fund the manufacturing buildout it has promised investors.

How does CSG's production capacity compare to Rheinmetall's?

CSG targets 1.1 million medium- and large-caliber rounds by end of 2028 and presents this as comparable to Rheinmetall's 1.1 million round target. Rheinmetall's 1.1 million figure refers specifically to 155 mm artillery shells; its total rounds target including medium- and other large-caliber ammunition is approximately 4.5 million. Rheinmetall spent nearly €500 million on a single greenfield German plant expected to produce 350,000 155 mm shells per year by 2027 and paid €1.2 billion to acquire a Spanish firm adding roughly 300,000 rounds per year. Rheinmetall's 2025 capex was nearly four times CSG's.
