NextFin News - The market’s latest defense debate is no longer just about how much governments plan to spend. It is about what kind of warfare investors think those budgets will buy. As Europe keeps pouring money into rearmament, strategists are starting to argue that drones, sensors, software and electronic warfare deserve a different valuation framework from tanks, artillery and frigates. That shift is pushing the defense trade away from a simple macro story and toward a stock-picker’s market.
Why Electronic Warfare Is Forcing A Valuation Reset
Joachim Klement, strategist at Panmure Liberum, says investors should rethink how they value defense companies because the next wave of winners may look more like software and AI groups than traditional arms makers. His argument is rooted in how modern conflicts are changing: electronic warfare, drone defense and AI-enabled systems evolve faster than legacy platforms and can be improved through software updates, sensors and data fusion rather than long industrial production cycles.
"Electronic warfare is a tech phenomenon," Klement said.
That matters because the market has spent years treating defense as a broad rearmament trade. The assumption was simple: higher budgets, fuller order books and a more hostile geopolitical backdrop should lift most listed contractors. But the more investors look at the composition of spending, the more they are separating conventional hardware from the technology layer that now sits inside battlefield systems.
Klement said the next generation of defense winners could increasingly resemble software and AI companies instead of conventional arms manufacturers. He also said some stocks in the sector could deserve a "much, much higher valuation" than companies tied to more conventional warfare. The message is not that tanks and artillery are obsolete. It is that the market may increasingly reward firms that sell adaptability, speed and software-defined capability rather than only steel, capacity and long production runs.
The debate comes as defense stocks in Europe have already rerated sharply over the past several years on the back of the Ukraine war, rising NATO spending, and repeated warnings that the continent needs to rebuild military inventories. But recent trading has shown that investors are becoming more selective. The biggest rerating happened when the market treated rearmament as a blanket buy signal. The next phase is about which companies are most exposed to drones, electronic warfare, air defense and autonomous systems.
That selectivity also helps explain why recent weakness in European defense shares has not been a straightforward verdict on the sector’s long-term demand story. Klement said the pullback reflects both a rotation into AI stocks and more careful investor flows. In other words, capital is not necessarily leaving defense altogether; it is moving toward the parts of defense that look most like the future of technology.
The Legacy-Program Problem
The clearest reason valuations are being questioned is that large defense programs can be vulnerable even in an era of higher budgets. Germany’s decision to cancel the F126 frigate project has become a case study in that risk. The move shows that governments can still walk away from expensive legacy platforms if they are delayed, costly or no longer aligned with current military requirements.
For investors, that is a warning against assuming that every extra euro or pound of defense spending will flow to the same companies in the same way. A modern defense budget can support munitions, electronic warfare, counter-drone systems, sensors, naval vessels and AI-enabled networks at once, but each category carries different economics. Some are more industrial; others are closer to technology. Some depend on volume; others depend on intellectual property and rapid iteration.
That is why the market is rethinking what should trade on a premium multiple. A frigate program can be cancelled. A software-defined electronic warfare system can be upgraded. A drone-defense network can be refreshed in months rather than years. Investors are starting to price that difference.
Europe’s defense groups themselves reflect that divide. BAE Systems and Leonardo are building systems that use AI and drone technology, while more traditional contractors remain associated with tanks, artillery and heavy platforms. The market’s new question is not whether defense spending stays high; it is which companies are best positioned to capture the fastest-growing and most technologically demanding parts of it.
What The Market Is Really Pricing In
The bull case for higher defense valuations rests on one simple idea: modern warfare is becoming more dependent on software, sensing and electronic attack. Drones are cheap to deploy and hard to stop. Counter-drone systems, by contrast, demand advanced detection, signal processing and integration across multiple platforms. That makes the segment feel less like old-line manufacturing and more like a technology race.
That shift matters for margins, not just growth. Software-heavy systems can often scale differently from heavy industrial platforms, and investors tend to reward businesses that can expand capability through updates rather than solely through larger factories. That is one reason the market is willing to think about defense in the same sentence as AI.
It also means the sector is moving from a one-directional macro trade to a more differentiated equity story. Broad rearmament still supports demand. But within that demand, investors are asking which companies will benefit from long-cycle procurement and which ones can monetize the fastest-changing battlefield requirements. The answer may not be the same across the industry.
For now, the most important takeaway is that defense valuation is no longer only about peace and war, or even about the size of government budgets. It is increasingly about the technology content inside each contract. That is why electronic warfare is being treated less like a niche capability and more like a signal that the market’s definition of defense has changed.
The next test is whether companies can prove that promise in actual orders, margins and program wins. If they can, the premium will broaden. If they cannot, the market will keep rewarding only the names that look most like tomorrow’s battlefield.
