CSG's Half-Year Numbers Show a Group in Overdrive — But the Share Price Tells a Different Story

CSG's H1 shows 17.2% revenue growth and record €46B backlog, yet shares fell 6.9% amid high volatility and negative cash flow.

The arithmetic of CSG's first half is straightforward enough: revenue up, profits up, order book at a record. The market's reaction, however, has been anything but simple. Shares in the Dutch defence group closed Friday at €18.10, down 6.88 percent on the day — a pullback that looks jarring next to the operational momentum in the numbers released just days earlier.

Yet context matters. Over the past 30 days, the stock is still up 28.37 percent, and the annualised volatility sits near 65 percent. Investors have grown accustomed to sharp swings around CSG's quarterly updates, and Friday's dip fits that pattern rather than signalling any loss of faith in the underlying business.

The Order Book Keeps Growing

CSG's backlog, including pipeline, has expanded from €44 billion in March to €46 billion, with the Land Systems division remaining the principal driver. The group confirmed its full-year guidance: revenue of €7.4 billion to €7.6 billion and an EBIT margin between 24 and 25 percent. With roughly 43 percent of the annual revenue target already banked after six months, the forecast looks credible without being stretched.

First-half revenue climbed 17.2 percent to €3.251 billion, while operating profit rose 12.7 percent to €784 million, leaving the operating margin at 24.1 percent — inside the company's own target range. Net income jumped 84.8 percent to €572 million, and EBITDA grew 11.5 percent to €863 million.

A Shifting Customer Base

The Defence Systems segment remains the growth engine, with revenue up 27 percent and now accounting for roughly 80 percent of group sales. Just as notable is the changing shape of the customer book. Ukraine's share of revenue has fallen from 27 percent to around 20 percent, while NATO states and allied countries now contribute 83 percent of sales — up from 73 percent previously. That shift reflects a deliberate strategy to broaden the client base beyond a single conflict scenario.

Production capacity is being scaled up in parallel. Output of large-calibre ammunition is set to reach 850,000 rounds by the end of 2026, and production of the Karpat battle tank is scheduled to begin in the first quarter of 2027.

Cash Flow Remains the Constraint

Rapid growth has its costs, and CSG's cash flow statement shows where. Operating cash flow before taxes came in at minus €411 million, weighed down by elevated working capital tied to strategic stockpiling of medium- and large-calibre ammunition. Management expects to unwind much of that effect in the second half, particularly in the fourth quarter.

Net debt stood at €2.914 billion at the reporting date, equivalent to 1.6 times trailing twelve-month EBITDA. The company remains committed to bringing that ratio below 1.3 times by year-end — a target that will require the promised working capital release to materialise.

A Week of Strategic Moves

The investment in North Vector Dynamics, announced just days after the results, fits neatly into CSG's broader push toward NATO-aligned business. The Canadian developer of air defence systems, precision-guided missiles, counter-drone technology and hypersonics — founded in 2022 and based in Calgary — is now valued at over $90 million. CSG has not disclosed the size of its stake, but will contribute its industrial base, technical expertise and international network, with an eye on NATO procurement. NVD has already secured a hypersonics contract from Canada's defence ministry.

On the production side, subsidiary CSG Energetic Materials Germany has acquired a 57-hectare industrial site in Gnaschwitz near Bautzen from MAXAM. The company plans to invest more than €100 million in the first phase, building capacity for nitroglycerin, nitroglycerin-based products and munitions components.

There have been personnel changes too. Ben Hudson joined the Czechoslovak Group board on 1 August as a member and deputy chairman, adding the role of Group Chief Technology Officer to his existing position as managing director of CSG Land Systems. Hudson brings over three decades of defence industry experience.

Meanwhile, AviaNera Technologies, a CSG group company, has signed a strategic cooperation agreement with Ukrainian Armor covering propulsion systems for Ukrainian guided missiles and unmanned platforms. The deal includes engines across various power classes, with plans for a joint venture, local manufacturing capacity and technology transfer in Ukraine.

The Two-Sided Picture

The share price remains roughly half its 52-week high of €36.05, reached on 26 January. The Relative Strength Index of 61.5 suggests the stock is not acutely overbought, but the recent volatility underscores how sensitive the valuation is to individual news items — whether quarterly reports or strategic announcements.

For investors, CSG presents a split personality. Operationally, the company is growing rapidly, its order book is at a record, and the customer base is becoming more diversified across NATO demand. At the market level, though, the stock continues to swing sharply, and Friday's decline is a reminder that strong fundamentals do not automatically translate into stable share price performance.
