Buying the Beta

These names re-rated the moment NATO’s spending trajectory became policy. The alpha, the gap between what careful work reveals and what the price already reflects, is mostly gone. That is usually where the value reflex says to move on.

Here it does not. What is left after the re-rating is beta. European beta specifically, in a sector that was an American franchise for decades, with a margin of safety underneath it. That is worth more than it sounds.

The change is structural, not cyclical

For twenty years NATO’s spending commitment was a 2% of GDP guideline most members treated as optional. In June 2025, at the Hague summit, that changed. Every member except Spain committed to 5% of GDP by 2035: 3.5% on core defense, 1.5% on defense-related spending, reviewed in 2029.

The target more than doubled, and it is a floor with a ten-year runway. European allies and Canada already lifted combined defense spending by roughly 20% in real terms in 2025 against 2024. Europe under-armed for a generation and is now rebuilding on a legislated schedule. That creates a large new market where one barely existed, and it hands the companies serving it a rare asset: multi-year revenue visibility. For a group of industrials, the earnings consistency here looks closer to a subscription business than to a defense cycle.

You are not buying a mistake the market made. You are buying the exposure it priced correctly.

The interesting layer sits below the primes

The primes got the first bid. Rheinmetall, Leonardo, BAE. The more interesting exposure sits one layer down, in the subsystems and components every prime has to buy no matter who wins the contract.

• Exosens (EXENS). ITAR-free image intensifier tubes. About as close to a component monopoly as exists inside NATO night vision. The purest picks-and-shovels play on the spend.
• RENK Group (R3NK). Tank transmissions and naval gear. The machine inside the machine. Backlog in the billions and direct leverage to the land rebuild.
• Kongsberg Gruppen (KOG). Nordic defense and maritime. NSM and JSM missiles, remote weapon stations, naval systems. Diversified and defense-levered.
• Theon International (THEON). Founder-led night vision and thermal. Direct European NATO procurement and roughly mid-20s EBIT margins. These are quality businesses standing in front of a spending wave that is now policy rather than forecast.

Consolidation is a free option

There is a bonus worth naming but not underwriting. European defense is fragmented relative to the US, and the political will to build continental champions is real. RENK already carries a large strategic holder on its register. If cross-border M&A accelerates, several of these names become targets or acquirers. None of that has to be paid for. If it happens, it is upside on top of a thesis that does not need it.

The easy money already moved. What remains is not a mispricing to exploit. It is a structural exposure: durable European beta with earnings support and a margin of safety, in a corner of the market Americans have historically had no clean way to own. The downside is defined by real backlog and real margins rather than by a story. The point is not to be cleverer than the market. It is to own the right beta before the ten-year part of a ten-year story has played out.
