## Introduction: The stock market crash that shook European defence

### A historically black day

The **24th of June 2026** will go down in stock market history as the worst day in the history of **Rheinmetall AG**. Shares in the German defence giant fell by **nearly 19%** on the Frankfurt Stock Exchange — its steepest single-day decline on record. In a single session, **more than 10 billion euros** in market capitalisation were wiped out. The stock, which had reached a high of **2,008 euros** in October 2025, was trading around **946 euros** that day — a collapse of more than **53% from its peak**. The entire European defence sector reeled: **Hensoldt lost 6.7%**, **Renk 2.5%**, **Saab 2.6%**, **Leonardo 3.5%**, **BAE Systems 1.6%**.

The immediate cause? **The German government cancelled the F126 frigate programme**, a contract that **Rheinmetall** had been on the verge of winning, valued at up to **12.8 billion euros**. Berlin instead chose to order eight smaller **Meko A-200** frigates from naval shipbuilder **TKMS** (ThyssenKrupp Marine Systems), whose shares surged **+16%** the same day. While Rheinmetall collapsed, its rival smiled.

### The decision that triggered everything

**German Defence Minister Boris Pistorius** confirmed the end of the F126 programme on June 24. The reasons cited: "**considerable delays**," an "**explosion in costs**," and a final bill estimated at more than **18 billion euros** for six vessels — against an initial estimate of **10 billion**. Rheinmetall had acquired the **NVL (Naval Vessels Lürssen)** shipyard in March 2026 for **1.5 billion euros**, precisely to become the prime contractor for this programme. That strategic acquisition has now lost a large part of its rationale. **Around 2 billion euros** of public spending committed to the F126 programme will have to be written off, according to financial press estimates.

*There is something deeply revealing about this crash. For years, Rheinmetall was presented as the perfect symbol of European rearmament — a safe bet, guaranteed growth, a continental industrial success story. The 19% single-day drop is the market saying: "We no longer believe in it as much as before."*

## The rearmament narrative: between reality and promises

### Five years of spectacular rise

To understand the scale of the fall, one must measure the rise. Since Russia's all-out war against Ukraine began in **February 2022**, **Rheinmetall** had become one of the most sought-after stocks among global investors. Its share price had **gained more than 1,000% in five years**, according to **Handelsblatt**. The logic was simple and seemingly bulletproof: **NATO** member states were committing to spend **2%, then 3%** of their GDP on defence; **Rheinmetall**, Europe's largest ammunition manufacturer and leading armoured vehicle supplier, was ideally positioned to capture this windfall. **Germany** itself had finalised its 2027 budget with defence raised to **3.1% of GDP**, according to Franklin Templeton.

**Rheinmetall's** order backlog had reached **73 billion euros**. Projections for 2030 spoke of a turnover of **20 billion euros** in naval activities alone. **Morgan Stanley** analysts had made the company their "**top pick**" in the European defence sector. Everything looked perfect. Too perfect.

### The fiction of "promised" orders

The problem with European rearmament is that it rests on **political declarations** that do not always translate into **signed contracts**. Rheinmetall had incorporated the F126 contract into its projections as a near-certain win. CEO **Armin Papperger** had even declared at a results conference that signing was "**imminent, probably before the end of Q2**." This confident communication, reckless in hindsight, amplified the market's reaction when the cancellation was announced.

*I am not a portfolio manager, but the lesson seems clear: political promises on defence are only worth what actual budgets and real trade-offs confirm. Europe has been promising to rearm for four years. The question is how many of those promises translate into steel, ammunition, and firm contracts — and this Rheinmetall crash suggests the answer is: fewer than expected.*

## What the Rheinmetall collapse reveals about German industrial governance

### A poorly managed programme from the start

The history of the **F126** programme is one of accumulated poor industrial and political decisions. Originally entrusted to Dutch shipyard **Damen Schelde Naval Shipbuilding**, the programme accumulated delays and cost overruns to the point where Damen was deemed unable to deliver. Berlin then sought a new prime contractor — and that is where **Rheinmetall**, via its acquisition of **NVL**, seemed the ideal solution. But the cost of continuation exploded: from **10 billion initially to more than 18 billion**, including a contract of **15.2 billion** with **NVL** alone. At that point, Berlin chose to cut its losses.

The final decision to go with **TKMS** and its **Meko A-200 frigates** — less ambitious but proven — reflects a pragmatic philosophy: better a vessel delivered than six dream frigates that never arrive. This pragmatism is sound, but it comes after years of chaotic management and **2.3 billion euros** already spent with nothing concrete to show for it.

### The consequences for Rheinmetall's credibility

**Morgan Stanley** removed **Rheinmetall** from its priority list in the European defence sector, now preferring **BAE Systems**, while maintaining an "**Overweight**" rating. The **Jefferies** analyst cut their price target by **31%, to 1,300 euros**. **JP Morgan** notes that the company "**will likely not meet its order intake target** of 80 billion euros in 2026." However, most analysts maintain a long-term buy recommendation, noting that the drop seems disproportionate relative to the company's fundamental value — its order backlog remains solid, and land weapons and ammunition activities are booming.

*The paradox is real: Rheinmetall remains a fundamentally strong company, with a 73-billion-euro order backlog and a dominant position in ammunition, armoured vehicles, and weapons systems. But financial markets didn't pay for that company — they paid for a naval growth premium that has just evaporated. The correction is painful but perhaps healthy.*

## The barometer of investor confidence in European rearmament

### What the market is really pricing

The Rheinmetall collapse is a signal that investors are beginning to distinguish between **real defence spending and political promises**. When contracts fail to materialise, when programmes are cancelled, when costs explode — the market corrects. This is not necessarily a vote of no confidence in European rearmament in general, but a reassessment of risks specific to **Rheinmetall**. **TKMS's** surge of **+16%** the same day confirms it: investors did not flee the defence sector, they reallocated positions toward a player considered more reliable in execution.

Meanwhile, the Franco-German group **KNDS** (manufacturer of the Leclerc and Leopard tanks) announced on **June 24** its intention to list on **Euronext Paris and the Frankfurt Stock Exchange**, targeting a summer 2026 window. This IPO confirms that capital remains available for the defence sector — but only if companies can demonstrate **credible industrial execution**.

### The risks of a fragmented rearmament

Europe is rearming, but in a fragmented way — country by country, with national logics that sometimes clash with collective efficiency. **Germany** cancels the F126 for cost reasons but maintains its **3.1% of GDP** target. France maintains a digital tax that **Washington** threatens to punish with tariffs. The whole picture lacks industrial and strategic coherence. **The market senses this and punishes it**.

*I am convinced that Europe must rearm — and quickly. But the way this rearmament is managed, with programmes cancelled after billions spent, mid-course changes of prime contractor, runaway costs, suggests deficient industrial governance. You cannot build a credible continental defence on such unstable managerial foundations.*

## What Wall Street says about Rheinmetall's future and the sector

### Current valuation: risk or opportunity?

At **946 euros on June 25, 2026**, **Rheinmetall** shares trade at a **P/E of 30.94 for 2026**, according to market data. The average analyst price target stands at **1,868 euros** — representing an upside potential of nearly **100%** from the current price. **Metzler** even targets **2,180 euros**, more than double the current price. These targets reflect the conviction that the European rearmament programme will eventually translate into firm orders, that ammunition and armoured vehicle activities remain structurally very solid, and that the post-F126 correction is excessive.

However, caution is warranted. **Rheinmetall's market capitalisation**, at approximately **42.5 billion euros** on June 25, remains considerable for a company whose key strategic acquisition just lost its flagship contract. The question is not merely whether the company can rebound, but whether it can do so **without significant restructuring of its naval division**.

### The lesson for investors in European defence

The **Rheinmetall** collapse illustrates a systemic risk for investors in European defence stocks: dependence on unpredictable political decisions. A contract can be **promised, announced, then cancelled** based on budgetary or political considerations that have nothing to do with the company's industrial quality. The defence sector is, by nature, a state-dependent sector. And states change their minds.

*What writing this column taught me is that the gap between the political narrative of European rearmament and the industrial and budgetary realities remains very wide. Europe wants to defend itself — that much is clear. But it has not yet resolved the question of how to finance, govern, and execute this rearmament in a coherent and sustainable way.*

## Germany and Europe: the rearmament promise tested by industrial realities

### The challenge of industrial conversion in peacetime Europe

On **June 24, 2026**, **Germany** confirmed its intention to raise defence spending to **3.1% of GDP in the 2027 budget** — a level the country has not reached since the **Cold War**. But this political will runs into a complex industrial reality. Germany's defence supply chains were dismantled or reduced during the **30 years of the peace dividend** that followed reunification. Rebuilding these capabilities takes time, requires training specialised technicians, and demands investments in facilities whose returns are measured in decades, not quarterly results.

The **Rheinmetall-F126** crisis illustrates this challenge precisely: even a large, established defence company with a **73-billion-euro** order backlog can underestimate the complexity of a major naval programme. The problem is not a lack of orders — it is the ability to deliver on time and within budget. **Europe** faces a paradox: demand for defence equipment is at a historic high, but the industry needs **several years to scale up responsibly**.

*There is an irony in the fact that financial markets, which inflated defence stocks for two years on rearmament promises, are now penalising the first real execution difficulties. They may have overpaid for hope. Today, they may be overpaying for fear. In both cases, it is the companies that have to manage industrial reality — not the traders.*

## KNDS, Thales, Leonardo: the beneficiaries cashing in on the Rheinmetall debacle

### A reshuffling of cards in the European defence sector

The **Rheinmetall** collapse is not a catastrophe for the entire European defence sector — it is a reallocation of opportunities. **TKMS**, whose shares surged **+16%** on June 24, is the immediate big winner from the F126 cancellation. But beyond that, other players benefit from the **readjustment of investment priorities**. The Franco-German group **KNDS**, manufacturer of the **Leclerc and Leopard 2 tanks**, announced that very same June 24 its intention to list on **Euronext Paris and the Frankfurt Stock Exchange**, targeting a summer 2026 IPO. This IPO, simultaneous with the Rheinmetall debacle, is no coincidence — **KNDS is riding the wave of capital** seeking European defence players seen as more reliable in execution.

**Morgan Stanley**, by removing Rheinmetall from its "top pick," handed that position to **BAE Systems** — a British company, which is itself a lesson for continental defence industries. **Thales**, **Dassault**, **Leonardo** — these companies with more diversified portfolios and stronger delivery track records are attracting more attentive looks from institutional investors. The Rheinmetall crisis could ironically **accelerate the sectoral diversification** that analysts had been calling for over months.

*There is an irony in the fact that the stock most penalised on June 24 is that of a German company, in the same week Germany reaffirmed its commitment to spend 3.1% of GDP on defence. Markets punish not ambition but execution. Germany wants to rearm — but if it cannot manage a frigate programme without seeing costs double, the question of industrial competence arises legitimately.*

## European rearmament under scrutiny: what is the 2026 balance sheet?

### Rising budgets but difficult industrial conversion

Four years after Russia's all-out war against Ukraine began, European rearmament is real but uneven. Defence budgets have risen in virtually every **NATO** member state. **Germany** created a **special 100-billion-euro defence fund** in 2022, now superseded and replaced by a structural increase to **3.1% of GDP** in the 2027 budget. **Poland** spends more than **4% of its GDP** on defence — the highest rate in NATO. Orders for artillery, ammunition, and armoured vehicles have exploded.

But converting **budget euros** into real military capabilities takes time — far more time than political speeches suggest. Delivery timelines are lengthening. Supply chains are under strain. Shortages of **propellant powder, electronic components, and skilled labour** are delaying programmes. The F126 fiasco is a symptom of this reality: the European defence industry is not yet sized to absorb such a brutal, simultaneous surge in orders across all segments.

*The real lesson of the Rheinmetall crisis may not be that markets are wrong about European rearmament — it's that they had priced in a success premium too aggressively. Rheinmetall is still a great company with a 73-billion-euro order backlog. It simply lost one contract it may have over-promised. The question is not whether Europe is rearming — it's whether it's doing so with the necessary industrial rigour. For now, the verdict is mixed.*

## Conclusion: Is the market the best analyst of European rearmament?

### A correction that clarifies priorities

The **Rheinmetall** collapse is not the end of European rearmament — far from it. It is a warning signal about how that rearmament is being conducted. **Massive programmes, mid-course changes of prime contractor, uncontrolled costs**: these are the symptoms of a defence industry that was not maintained at the level of need for decades and is now trying to catch up too fast, with too little rigour.

### A warning to European capitals

The market's message is clear: **investors fund companies that deliver, not political promises**. If Europe wants its defence industries to raise the capital needed for their scale-up, it must offer them stable contractual visibility, rigorous programme governance, and consistency in its commitments. The Rheinmetall crash of June 24 is a mirror held up to European governments. The question is whether they will look into it.

*The real lesson of June 24, 2026, is not that **Rheinmetall** failed — it's that financial markets had built a bubble of expectations around European rearmament that was disconnected from industrial realities. European rearmament is necessary, urgent, and I hope lasting. But it will happen at the pace of the real industry, not at the pace of stock market promises. And that pace takes years.*

## Columnist's transparency note

### Editorial stance

I am not a journalist but a **columnist and analyst**. My expertise lies in observing and analysing the geopolitical, economic and strategic dynamics that shape our world. My work is to take political strategies apart, to understand global economic movements, to put the decisions of international actors in context and to offer analytical perspectives on the changes that are redefining our societies.
