[HAG] Hensoldt: A Government-Approved Moat in Military Electronics
The transformation of military electronics, one radar at a time
Origins
The modern Hensoldt AG emerged from what you might call a Marie Kondo moment at Airbus. Sometimes you look at your defence electronics division and ask yourself if it sparks more joy as a separate company. In February 2017, Airbus decided that yes, it did. They sold 74.9% of their sensor technology business to KKR for €1.1 billion. The resulting company took its name from a 19th-century German optics pioneer, rooting itself in a tradition of precise German engin… wait a second. Isn’t Airbus… French? Yes, Airbus is indeed often thought of as a French company, but it's actually a pan-European aerospace corporation with significant operations and history across multiple countries, particularly France and Germany. The defence electronics division that became Hensoldt was primarily based in Germany, incorporating the heritage of several German defence electronics companies. Has no other connection to the Zeiss’ “Hensoldt” though. Just the name.
This spinoff brought together decades of German defence electronics expertise. Think of it as a consolidation of industrial giants: AEG, Dornier, Telefunken, and Siemens had all contributed their technological DNA. The resulting company specialized in military sensor technology. Their portfolio covered everything from radar systems to electronic warfare - the kind of equipment that modern armies can't function without.
By 2020, Hensoldt was ready for its public debut on the Frankfurt Stock Exchange. The listing caught the attention of some very particular investors. The German government moved first, securing a 25.1% blocking stake. Italian defence contractor Leonardo followed with their own matching stake. The resulting ownership structure spoke volumes: Hensoldt had become a strategic asset in European defence technology, with its shareholder register reading like a NATO meeting attendance sheet.
With the German government and Italy's largest defence contractor as its two biggest shareholders, Hensoldt's ownership tells you everything about its strategic importance. The structure is as deliberate as a central bank communiqué: about 48% locked up by national-security players, 12% held by policy-minded institutional investors, and the rest free-floating in the market. This ownership matrix ensures decisions flow from defence capability needs rather than quarterly earnings pressure – exactly what you'd want in a company building military sensor technology.
How do they make money?
In it’s simplest form, this company makes things that go "beep" when other things go "whoosh" through the sky.
On a more serious note, Hensoldt makes the electronic eyes and ears of modern military equipment.
When NATO countries need to know what's flying through their airspace or rolling across their borders, they're looking at it through Hensoldt's sensors. These are the crucial bits that help tanks and planes understand what's happening around them.
Military hardware without sensing capabilities is just expensive metal. Hensoldt sells the seeing, hearing, and understanding parts. Their core business breaks down into two main segments: Sensors (about 87% of revenue) and Optronics (the other 13%). The Sensors division dominates, bringing in €1.2 billion in the first nine months of 2024 alone.
The business model runs on pure industrial logic: large, long-term contracts from governments and defence contractors. Nobody impulse-buys a military-grade radar system. The process involves multi-year procurement cycles, detailed requirements documents, and enough paperwork to sustain several small forests. Their order backlog sits at €6.5 billion - essentially three and a half years of revenue already locked in.
The company's evolution reveals the real complexity of modern defence electronics. Hensoldt started as a pure hardware manufacturer and now operates as a "solution provider." Companies selling security cameras can charge more for providing entire integrated security systems with 24/7 monitoring. The same principle applies to military-grade sensors, with even better margins.
Their TRML-4D radar has become something of a celebrity in defence circles, especially after its performance in Ukraine's air defence systems. The hardware sales open the door for software, AI integration, and ongoing services. Military sensors operate like enterprise software - the initial sale leads to years of high-margin service revenue.
The geographic revenue split maps perfectly onto modern European defence politics: about 55-60% comes from Germany (thank you, Zeitenwende defense spending program), another 27% from the rest of Europe, and the remaining slice from the rest of the world. This home-field advantage in Germany, combined with their strategic shareholders, creates the kind of competitive position that makes investment committees write long memos.
Their acquisition of ESG (a military services company) pushes them further up the value chain. They've expanded from selling components to delivering entire systems and ongoing services.
The timing aligns with broader trends in defence spending. NATO countries are increasing military budgets, and European politicians emphasize strategic autonomy in defence procurement. Having the German government and Italy's largest defence contractor as your two largest shareholders positions you rather nicely for that particular trend.

Following the Money Trail
That valuation - 226x trailing earnings - looks stratospheric until you consider the order backlog. They've locked in €6.5 billion in future revenue. For context, that's nearly three years of sales already contracted.
That 20% adjusted EBITDA margin target? Pretty solid for defence electronics - higher than traditional defence manufacturers who hover around 12-15%, but lower than pure software companies. It's the sweet spot where hardware meets recurring revenue.
Book-to-bill at 1.3x means they're booking €1.30 in new orders for every €1 they bill. Think of it as next year's lunch already being ordered. Above 1.0 means growth; at 1.3, it's strong growth.
Revenue comes primarily from Sensors - €1.2 billion in nine months, representing 87% of total sales. They've graduated from selling components to delivering complete radar systems. The 25% year-over-year drop in pass-through revenue shows this transition.
The margin story centres on scale. They're targeting 20% adjusted EBITDA margins. Military contracts create enough one-time costs that adjusted figures give you a clearer view of actual performance. When you're ramping TRML-4D radar production from 2 units to 18 annually, operating leverage matters. What is operating leverage I hear you ask. Operating leverage is simple: Once you've built a radar factory, each additional unit costs less to make. When you go from 2 to 18 units annually, your fixed costs get spread thinner.
The Balance Sheet Story
Let's talk about what they owe and own. The €816 million in inventory (up from €625 million) sits alongside €374 million in contract assets. With an annual interest expense gap of €50 million against €41 million in EBIT, their financing costs demand attention in this rate environment.
Why do they need so much inventory? Good question. Well, when you're building radar systems that need to work perfectly every time (because the alternative is... uncomfortable), it’s not wise to just shop online for spare parts when you need them. Each component needs multiple backups, extensive testing, and enough spare capacity to handle urgent government orders (let’s hope it doesn’t get to that). That's why they keep more inventory than your average industrial company.
About that employee ownership - turns out 67% of employees own shares, but they're not alone. The German government holds 25.1%, Leonardo SpA has 22.8%, and institutions hold another 12.15%. That leaves about 40% trading freely.
The interest gap deserves attention: €50 million annually on €41 million EBIT means most operating profits are going to bondholders instead of shareholders. In a rising rate environment, that's like swimming with weights on. Yeah, not great.
Working capital at €816 million in inventory? Such a level would be concerning in most industries but is standard for defence contractors due to long production cycles. This working capital requirement is partially offset by €679 million in customer advances - a unique advantage of government contracts where customers provide upfront payments.
Add it all up: A €3.91 billion market cap defence electronics company, growing rapidly, backed by government contracts, trading at 226x earnings because those earnings are about to scale dramatically. The spreadsheet tells you what European rearmament costs, down to the last euro cent.
The Competition
Defence electronics competition works differently than regular markets. You don’t just comparison shop for military radar systems on Amazon.
The market divides into national champions. Thales dominates French defence electronics. Leonardo controls the Italian market. Raytheon leads in America. Each company operates from a protected home base, expanding internationally when possible.
Hensoldt fits this pattern perfectly. Their 60% revenue share in Germany isn't an accident. The German government's 25.1% ownership stake sends a clear message about national priorities. When the Bundeswehr needs new radar systems, they know who to call.
The real competition happens at two levels.
First, there's the technical race. Military sensors require constant innovation. Radar systems need to detect stealthier targets. Optical systems must see further in worse conditions. Electronic warfare capabilities evolve monthly.
Hensoldt spends 20% of revenue on R&D to stay competitive. Their TRML-4D radar's success in Ukraine proves they're keeping up. The constant innovation creates high barriers to entry. You can't just start manufacturing military-grade radar systems in your garage.
The second level is political-industrial competition. Defence procurement involves a complex dance of national interests, industrial policy, and military requirements. Having Leonardo as both competitor and 22.8% shareholder illustrates this dynamic. They compete in some markets and collaborate in others.
Actually, there’s a third level. It’s industrial scale. Defence electronics demands massive upfront investment. Each new radar generation costs hundreds of millions to develop. But once you've built the factory and trained the workforce, margins improve dramatically. Hensoldt's TRML-4D radar production is scaling from 2 to 18 units annually. Each new unit spreads those fixed costs thinner. Operating leverage as we said.
The ESG acquisition reshapes Hensoldt's position in all three arenas. Technically, they can now integrate entire systems rather than just supply components. Politically, they've deepened their role in Germany's defence infrastructure. Industrially, they've moved up the value chain where margins are higher and relationships stickier. It's the difference between selling someone a camera and running their entire security system. The margins are better, the relationships stickier, and the competitive position stronger.
The numbers support this strategy. Their 13.6% EBITDA margins exceed traditional defence manufacturers. The €6.5 billion order backlog provides visibility. The book-to-bill ratio above 1.3 signals growing market share.
Contract structures reinforce these dynamics. Early stage development uses cost-plus pricing, ensuring companies invest in innovation. Production contracts switch to fixed-price, rewarding efficiency. The whole system encourages technical excellence while maintaining industrial capacity.
This explains why defence electronics stocks trade differently than regular industrials. Hensoldt's seemingly high P/E ratio reflects their protected position and locked-in growth. When NATO countries commit to higher military budgets, the whole sector grows. The focus isn't on taking market share from competitors, but rather on capturing a stable portion of rapidly expanding defence budgets.
Defence electronics combines utility-like stability with technology growth rates. Understanding how competition really works here - through national champions and strategic alliances rather than pure market forces - explains why companies like Hensoldt can maintain both high margins and strong growth. The market isn't perfectly efficient, and that's exactly the point.
So what about the moat? Is there any?
Hensoldt draws its competitive strength from deep roots in German defence. Once their radar systems integrate into Eurofighter jets and Leopard tanks, they form a crucial piece of Germany's defence backbone. The qualification cycles alone make switching suppliers nearly impossible. When your radar needs an upgrade, you call the company that built it. When you need spare parts, same thing. When you want new capabilities, guess who already knows your systems inside out? This creates a form of technical lock-in that even the most efficiency-minded procurement officer can't ignore.
But technology moves fast, and this is where the moat gets leaky. Chinese companies are catching up in radar technology. Software is eating the world, even in defence. "Data is the ammunition of the battlefield today," as Dörre puts it, explaining how data needs to be “transferred into information in order to be able to have better situational awareness, make faster, better decisions and afterwards, translate that into precise engagements”. Quantum sensing could make current radar systems obsolete. Hensoldt needs to keep spending that 20% of revenue on R&D just to maintain their position. Their real vulnerability isn't losing current programs - it's missing the next technological shift. That's why the ESG acquisition matters so much. Moving up the value chain into systems integration gives them better visibility into future requirements. They're trading some of their component-level margin for better strategic positioning.
In defence electronics, like chess, you sometimes have to give up a pawn to protect your queen.
The People
Hensoldt's transformation runs through its management team. CEO Oliver Dörre, who took over in April 2024, brings a particularly relevant combination - he's both a software engineer and an ex-military officer (Oberstleutenant der Reserve). Before joining Hensoldt, he ran the German operations of Thales, giving him deep insight into exactly the kind of company Hensoldt aims to become. The German government's 25.1% stake means they had a say in his selection, and they chose someone who speaks both the language of software and the language of defence procurement.
The company's 6,907 employees (as of 2023) skew younger than you might expect for a defence contractor - average age has dropped from 46 to 44 since 2017, no small feat when your existing employees are aging every year. Two-thirds of them own shares in the company, which tells you something about both employee belief in the mission and management's alignment of incentives. With 112,000 hours of professional training completed in 2023 and 400+ training programs aligned with strategic planning, they're investing heavily in upskilling their workforce for the software transition. When your business model requires combining radar expertise with artificial intelligence, keeping your engineering talent current becomes a strategic imperative.
What Does Mr. Market Think?
The stock market tells us a clear story about Hensoldt. In 2023, the stock climbed from €23 to €36 - a 50% gain that outpaced both the German DAX (+22%) and traditional defence peers like Thales (+6%).
Early in 2023, investors viewed Hensoldt as a conventional defence contractor. By mid-year, as the ESG acquisition settled and European defence spending looked increasingly structural, the market began pricing a different story. Today's valuation - 32.6 times forward earnings - suggests investors see Hensoldt as a hybrid: part defence contractor, part technology company.
The current €33-37 trading range captures an interesting tension.
The lower bound represents Hensoldt's value as Germany's leading defence electronics player with €6.5 billion in orders. The upper bound prices in their transformation into a software-defined defence company. Daily price movements mostly depend on which story investors focus on that moment.
Two simple facts explain the premium valuation.
First, Hensoldt gets 60% of revenue from Germany during the largest defence modernization in generations.
Second, they're moving from selling components to delivering entire systems and software solutions. The market prices this combination more aggressively than either pure defence exposure or traditional industrial transformation.
The ownership structure - German government, Leonardo, long-term institutions - suggests this isn't a story about quarterly earnings beats.
The market is pricing a multi-year transformation of European defence technology. Whether that premium valuation holds depends entirely on Hensoldt executing this vision.
Bear Thesis
Hensoldt looks like a classic growth story in European defence. Strong order books, expanding margins, rising military budgets. The kind of stock that makes perfect sense until it doesn't.
The debt structure tells the first chapter of our bear tale. Hensoldt carries 2.9x leverage after acquiring ESG. Their interest expense runs €74 million annually against €41 million in operating profit. Most operating earnings flow to bondholders. With ECB rate cuts likely moving gradually through 2025, that math stays tight.
Think about working capital next. Inventory grew to €816 million from €625 million. Defence companies always run high working capital - that's industry physics. Yet financing inventory growth while carrying substantial debt creates real constraints, especially as German inflation pushes back up to 2.8%.
The technology transition adds complexity. Hensoldt aims to evolve from radar hardware into integrated software solutions. Traditional defence contractors tend to struggle with this evolution. The required capabilities differ fundamentally. The talent pool shifts entirely. The revenue recognition changes dramatically.
When these elements converge, the deeper bear thesis emerges. Consider what happens when a company attempts multiple transformations while carrying significant leverage during a period of sticky inflation. Their degrees of freedom shrink precisely when they need maximum flexibility.
Some scenarios to ponder,
The rates spiral: ECB cuts move slower than markets expect. German inflation stays stubbornly high. Integration costs creep up. Working capital demands increase. The financial equations stop computing, forcing either dilutive equity raises or asset sales.
The transformation gap: The software transition creates execution gaps. Key talent departs. Legacy customers hesitate. New competitors emerge on both flanks. The company ends up stuck between traditional defence and pure software players.
The political pivot: February's German elections shift priorities. NATO dynamics change under Trump. An unexpected peace dividend emerges. Defence budgets face renewed scrutiny. The growth story loses its foundation.
Some contrarian notes worth considering: Defence electronics companies have historically managed high leverage through cycles. Customer prepayments do provide working capital relief. And major defence contractors have successfully navigated technology transitions before, albeit slowly.
Yet at 226 times trailing earnings, the market leaves minimal room for error. The valuation demands perfection across multiple dimensions - flawless ESG integration, seamless technology evolution, stable defence spending, precise capital allocation.
Markets consistently underestimate the complexity of simultaneous transitions. In defence particularly, where procurement cycles stretch long and relationships run deep, change happens gradually - until suddenly it accelerates.
Perhaps the clearest warning sign sits in those interest coverage ratios. When your operating profit barely covers interest expense, you're one surprise away from serious constraints. In defence electronics, surprises tend to arrive unannounced.
Bull Thesis
The simplest version of the Hensoldt bull thesis goes like this:
Europe needs better military sensors.
Hensoldt makes military sensors.
Europe has committed to spend more money on defence.
Therefore, Hensoldt should make more money.
That's true, but incomplete. The real bull thesis has three layers, each more compelling than the last.
Layer one is pure market dynamics. NATO countries pledged to spend 2% of GDP on defence. Twenty-three of them will hit that target in 2024. Germany specifically earmarked €100 billion for military modernization. When defence budgets expand, companies with large market shares tend to grow even larger.
Layer two involves technological positioning. Modern military equipment depends increasingly on electronic systems. A tank without advanced sensors is just an expensive metal box. Hensoldt evolved from making individual components to delivering entire sensing systems. Their TRML-4D radar production jumped from 2 units annually to 18. That's the kind of scaling that transforms margins.
Layer three gets structural. The German government owns 25.1% of Hensoldt. Italy's largest defence contractor owns another 22.8%. This ownership structure creates a protected position in European defence procurement. Think of it as a moat with government approval.
Some probable scenarios emerge from these layers:
The Base Case: European defence budgets follow through on committed increases. Hensoldt converts its €6.5 billion order backlog into revenue. Margins expand as production scales. The stock trades up gradually as earnings materialize.
The Software Scenario: Hensoldt successfully transitions from hardware to "software-defined defence." Their sensors generate recurring service revenue. Margins exceed the 20% target. The market re-rates the stock to reflect this higher-quality earnings stream.
The Integration Scenario: The ESG acquisition accelerates Hensoldt's evolution into systems integration. They capture more value per contract. Customer relationships deepen. The stock's multiple expands to reflect this enhanced market position.
A low-probability but high-impact scenario deserves mention: The NATO Response Scenario. Increased tensions drive NATO to raise its defence spending target above 2%. European countries accelerate procurement. Hensoldt's order book doubles again. The stock reprices dramatically to reflect this step-change in growth.
"Germany has roughly 300 main battle tanks in its entire arsenal. While Russia produces that number in under 3 months. China now has the largest navy in the world by number of hulls, roughly 50 more than the U.S. Navy."
-CEO Oliver Dörre
These scenarios share a common thread:
It’s essentially capturing a growing share of an expanding market.
That's a crucial distinction in defence electronics.
The numbers support this framework. Hensoldt grew its order backlog from €2.2 billion in 2019 to €6.5 billion today. Their book-to-bill ratio sits at 1.3x, meaning new orders exceed current revenue by 30%. Customer-funded R&D is increasing from 8% of revenue to 15%. These metrics suggest momentum rather than speculation.
The ESG acquisition looks particularly strategic through this lens. It added integration capabilities just as military customers shift toward complete solutions rather than individual components. The timing aligns with increased defence spending and the push for European strategic autonomy.
The company's talent profile - a software-savvy ex-military CEO from Thales running a workforce that's getting younger and owns the stock (67% are shareholders) - suggests they have the team to execute this transition.
Consider also the marginal economics: Once you've built a radar factory and trained the workforce, each additional unit improves margins. When defence budgets expand steadily rather than cyclically, those economics compound.
The market currently prices Hensoldt at 32.6x forward earnings. That multiple reflects both guaranteed growth from the order backlog and optionality from expanding budgets.
Reading the Radar
Look, to make it simple:
If you believe military procurement is genuinely transforming from buying hardware to buying integrated systems, and you think European defence independence is more than just political talk, Hensoldt sits in a sweet spot. They've got the government relationships, they're building the software capabilities, and they're positioning ahead of this shift. Oh yes, they also have to deliver that transformation with success.
But if you suspect interest rates will stay high while defence spending gets caught in political gridlock – especially in Germany – then a company trying to transform while juggling high working capital needs and thin interest coverage is exactly what you don't want in your portfolio. The margin for error here is slim.
In essence, Hensoldt represents a play on three converging trends: the structural increase in European defence spending, the rising importance of electronic systems in military equipment, and the shift from hardware components to integrated solutions. The €6.5 billion order backlog provides a floor, while the potential software transition offers upside. At 32.6x forward earnings, you're paying a premium for this transformation - but in defence electronics, government relationships and incumbent positions tend to compound over time.
The stock's daily moves track German defence budget news, but its long-term value depends on executing this industrial evolution. Like chess pieces advancing steadily across the board, Hensoldt's strategy requires both patience and precise positioning. The market prices the destination rather than the journey.
