CSG's Polish Trade-Show Debut Masks a Deeper Question About Where Its Cash Is Tied Up

CSG's H1 revenue rose 17.2% to €3.25B, but negative operating cash flow and inventory build weigh on shares, down 11% weekly.

When CSG rolls into Kielce this week for the MSPO defence exhibition, the Czech group will be showcasing more than just hardware. Seven of its subsidiaries — Tatra Export, Excalibur Army, Tatra Defence, MSM Group, Vývoj Martin, AviaNera Technologies and CSG Polska — are appearing alongside Polish partner Domar MS, with the third-generation Tatra Force eight-wheel-drive vehicle making its public premiere. Also on display: 155mm NATO-standard artillery ammunition, training rounds and command-and-communication shelters.

The timing is telling. The company is presenting a confident, product-led face to the world at a moment when its share price tells a rather different story. The stock has been sliding for weeks, and the reasons have less to do with how the business is performing than with how much cash it is currently locking up in inventory.

The Numbers Tell Two Stories

CSG's first-half results, published in early August, were objectively strong. Revenue climbed 17.2 percent to €3.25 billion, operating EBIT rose 12.7 percent to €784 million — a margin of 24.1 percent — and net profit from continuing operations jumped 84.8 percent to €572 million. Defence Systems, the division feeding NATO governments' frantic restocking of ammunition depots, saw sales surge 27 percent.

Then comes the counterweight. Operating cash flow before tax was negative to the tune of €411 million, a direct consequence of what management describes as strategic stockpiling of components, particularly in medium- and large-calibre ammunition. The company has guided that net working capital will stay below 20 percent of revenue for the full year, with the inventory build expected to unwind in the second half — most likely in the fourth quarter.

That timeline is what appears to be spooking investors. In German trading this week, the shares changed hands at around €17.26, down 9.8 percent over seven days. The picture is marginally worse from the vantage point of the primary article's data: €17.07, an 11 percent weekly decline and an 8.1 percent monthly drop. Either way, the stock now sits roughly 52 to 53 percent below its 52-week high of €36.05, reached at the end of January.

A Stock Under Multiple Pressures

The recent weakness is not solely a working-capital story. Since May, the shares have laboured under the shadow of two reports from short-seller Hunterbrook Capital, which questioned CSG's production capacity, business model and IPO disclosures — alleging the company leans more heavily on refurbishing and reprocessing ammunition than on its own manufacturing. CSG dismissed the claims as inaccurate and selective, issuing a detailed defence of its disclosures and governance. The first report knocked roughly 13 percent off the share price in one go, and the distrust has lingered.

Sector dynamics have compounded the problem. European defence stocks broadly have lost their shine — Rheinmetall, a bellwether, is down around 30 percent year-to-date. For CSG, that means even genuinely positive operational news fails to move the needle. Recent contract wins — bridge-layer orders worth more than $50 million from customers in Europe, the Middle East and Southeast Asia, plus a Nordic police award for duty and training ammunition secured by Federal Ammunition, part of the Kinetic Group — would normally have provided momentum. They have not.

Technical indicators paint a picture of a market that is cautious but not panicked. The RSI sits at 43.3 to 44.6, depending on the day, and the share price hovers just above its 50-day moving average of roughly €16.42 to €16.51. With annualised volatility around 55 percent, this remains a nervy stock to hold. The gap to the 52-week low of €12.20 still amounts to about 41 percent.

The Order Book Offers a Counter-Narrative

Set against the cash-flow drag is a backlog that keeps expanding. Total orders, including contracts under negotiation, have grown from €44 billion in March to €46 billion. Notably, Land Systems has become the largest single contributor — evidence that CSG is diversifying beyond ammunition production into a broader defence franchise, even if that shift will take time to show up in the earnings mix.

Management has also moved to bolster its leadership bench. Ben Hudson, a defence-industry veteran with more than three decades of experience, joined the board as vice-chairman about a month ago. The appointment initially lent the stock some support — it gained 3.8 percent in the weeks that followed — before the latest soft patch set in.

What Would Restore Confidence?

One overhang that has gone quiet: CSG's reported interest, revealed in May, in acquiring a stake in KNDS, the Franco-German tank maker behind the Leopard 2 and Caesar artillery systems. Any investment ahead of KNDS's planned IPO could have proven politically sensitive, particularly given the potential for resistance in Paris and Berlin. Whether CSG is still pursuing the idea remains unclear.

For now, the MSPO stage in Kielce offers the company a chance to rebuild trust through visible, tangible products. But the central question for investors is more prosaic: whether the inventory overhang really does unwind in the fourth quarter as promised, and whether operating cash flow normalises accordingly. Until that happens, the share price looks likely to remain caught between operational substance on one side and a lingering credibility discount on the other.
