Europe Is Rearming. Here Is Who Gets Rich

Intelligence on European defence M&A for senior decision-makers

Publication: The Interlock

BOTTOM LINE UP FRONT

European defence M&A is running at its hottest rate in thirty years, but the investors piling into Rheinmetall at 31-34x EV/EBITDA are betting on execution rates that European procurement has never delivered. The real money is elsewhere. The sector is bifurcated: traditional primes (BAE Systems, Leonardo, Thales) trade at 14-20x; re-rated names (Rheinmetall, Saab) at 31-35x. The value is in mid-cap UK defence firms, Tier-2/3 European suppliers (the companies one and two steps below the major manufacturers in the supply chain), and munitions producers where years of earnings visibility are not yet in the price. And one structural variable changes every cross-border deal model: the SAFE regulation’s eligibility rules now determine whether a target company can access €150bn in EU procurement contracts, and a non-EU acquisition can destroy that access on day one of closing.

1. THE DEAL PIPELINE: TRANSACTIONS IN PLAY OR LIKELY (NEXT 6-12 MONTHS)

Confirmed and Announced Transactions

Project Bromo (space satellite merger)
Airbus (35%), Thales (32.5%), Leonardo (32.5%). Est. value: ~$11.6bn. Framework agreement reached Oct 2025. EU antitrust review pending. Target close 2027. Confidence: almost certain to proceed.

KNDS dual-listing IPO
Franco-German tank and artillery JV. Up to €5bn raise; €20-25bn valuation. Investor meetings begun. Paris and Frankfurt listing targeted June/July 2026. KfW plans 25%+ blocking stake. Confidence: highly likely for 2026.

Rheinmetall acquisition of Iveco military truck unit
Acquiring from Leonardo (post-Iveco close). Value not disclosed. Contingent on Leonardo-Iveco completion. Regulatory review underway. Confidence: highly likely.

Leonardo-Rheinmetall Military Vehicles JV (LRMV)
50/50 JV, HQ Rome. Bundeskartellamt cleared Jan 2025. Awaiting Italian MoD contract award. Confidence: almost certain.

Leonardo acquisition of Becrypt
Acquiring UK cyber firm. Value not disclosed, likely sub-£100m. Binding agreement. Expected close Q2 2026. Confidence: almost certain.

PSM JV structure for future German MBT. German Federal Cartel Office approved Dec 2025. Confidence: almost certain.

Safran acquisition of Preligens
Acquiring AI/satellite intelligence software firm. €220m. COMPLETED early 2026.

Rumoured and Highly Likely Transactions (next 6-12 months)

Hensoldt bolt-on acquisitions — Elevated share price supports continued bolt-on strategy in sensors and electronics; 2-3 deals per year is the established pattern. Ongoing through 2026. Confidence: highly likely.

Saab M&A in electronic warfare and undersea — Well-capitalised; targeting Nordic and Baltic consolidation. Investor in Helsing. H2 2026. Confidence: likely.

MBDA ownership restructure — Governance pressure growing as partners scale missile production. Potential for one partner to increase stake or full corporate combination. 12-24 months. Confidence: realistic possibility.

Nammo ownership change — Critical European munitions asset (50% Norwegian state, 50% Finnish Patria). IPO or strategic investment possible. 12-18 months. Confidence: realistic possibility.

Further Rheinmetall acquisitions — Record 2025 sales; stated appetite for bolt-ons in electronics, munitions, and vehicle systems. Ongoing. Confidence: highly likely.

Key Deals to Watch in the UK Market

Chemring Group (market cap ~£1.5-2bn)
Munitions, countermeasures, sensors. P/E ~27-28x on thin net margins (0.64%). EV/EBITDA of 16.6x is more grounded, and at that level Chemring is modestly valued relative to sector peers. The high P/E on thin margins reflects the market pricing future earnings growth rather than current profitability. Value unlock for a buyer who can drive margin improvement. Likely acquirers: European primes (Rheinmetall, Thales), PE take-private. Confidence: realistic possibility.

Filtronic (market cap ~£200-300m)
Niche RF/microwave specialist, tier-1 MoD supplier. Contracts with Leonardo, QinetiQ, and BAE Maritime. Strategic fit for any prime building UK electronics capability. Likely acquirers: BAE Systems, Leonardo, Thales, or PE. Confidence: likely in 12-24 months.

Cohort plc (market cap ~£560m)
Defence technology group (EID, MASS, MCL, SEA). Capabilities across EW (electronic warfare — systems that detect, jam, or deceive enemy radar and communications), naval systems, and training. Consolidation candidate at accessible scale. Likely acquirers: mid-market PE, or bolt-on by a prime. Confidence: realistic possibility.

Tekever (UK operations) (part of unicorn group)
Acquired West Wales Airport for UAS testing. Growing UK MoD presence. Acquirable as part of a wider Tekever transaction. Likely acquirers: European drone consolidators. Confidence: realistic possibility.

Babcock International (market cap ~£6.2bn)
Nuclear submarine support, maritime services, aviation MRO. One of the largest UK MoD contractors by revenue. EV/EBITDA 11.6x, modestly valued despite 84.5% 52-week return and a core position in UK strategic defence. The nuclear and submarine capability makes it a sensitive acquisition target; full foreign ownership is unlikely but a partial stake or JV is plausible. UK MoD influence makes full foreign acquisition unlikely. Domestic PE or partial stake more realistic. Confidence: realistic possibility.

Smaller specialists (various, sub-£100m)
Pipeline of firms across autonomy, AI, secure comms, and space components. Several already at tier-1 or tier-2 MoD supplier status. Likely acquirers: primes, PE, or European mid-caps. Confidence: highly likely (several).

That deal pipeline reflects the capital allocation patterns beneath it.

2. SECTOR MAPPING: WHERE IS CAPITAL FLOWING?

The Heat Map

Missile Systems (consolidated, high capital via existing primes)

Sub-Sector Detail

AI / Autonomy / Drones (Red Hot)

Helsing: valued at €12bn after €600m Series D (June 2025); confirmed by Tech.eu and PitchBook. Some 2026 reporting puts the current valuation at approximately $14bn following further investor activity. Total raised: €1.37bn. Delivering “several hundred” HX-2 loitering munitions per month to Ukraine. Won €269m Bundeswehr contract (Feb 2026) with framework option up to €1.46bn.

“Sovereign M&A” trend emerging: US vendors acquiring European firms for NIS2/Cyber Resilience Act compliance.

Understanding where capital is flowing matters only if valuations still leave room for return.

3. VALUATIONS: CURRENT MULTIPLES AND HISTORICAL COMPARISON

Where the Sector Trades Today (Q1 2026)

The sector is bifurcated, not uniformly expensive. The premium is concentrated in re-rated names and munitions specialists, not across the board.

Sector index (EV/EBITDA): Wide range, 14-60x. Median ~20x. Traditional primes (Leonardo, Thales, BAE) at 14-20x. Re-rated names (Rheinmetall, Saab) at 33-35x. Munitions specialists (Kongsberg, Elbit) at 49-60x. Historical 5-year average: ~10-13x. US sector: ~14-16x.

Rheinmetall (EV/EBITDA ~31-34x): Peaked at 42.8x in Sep 2025. GlobalData: 31.08x at 31 March 2026. Bloomberg: 33.7x at Dec 2025. Historical average ~10-12x. Extreme premium reflecting backlog growth; multiple has compressed from 2025 peak.

QinetiQ (P/E ~15-16x; EV/EBITDA 11.32x): Source: investing.com, April 2026. Historical average ~14-16x. Among the most modestly valued UK defence names. Services model keeps multiples lower. Supports the value-in-UK-mid-caps argument.

Chemring (P/E ~27-28x; EV/EBITDA 16.6x): Source: investing.com, April 2026. Historical average ~15-18x. EV/EBITDA in line with traditional primes (Leonardo 14x, Thales 17.6x). Modest valuation relative to sector re-rating reinforces acquisition target thesis.

Saab (~35x EV/EBITDA): 35.4x confirmed via investing.com peer comparison (April 2026). Historical average ~12-15x. Nordic premium, strong order pipeline.

Hensoldt (~30x EV/EBITDA): 30.3x confirmed, investing.com April 2026. Historical average ~12-14x. Sensor and electronics premium; re-rated significantly, now trading in line with Rheinmetall range.

Note: multiples sourced from Bloomberg, GlobalData, and investing.com (April 2026). All figures on a trailing basis.

Valuation Assessment

Where value remains:

Mid-cap UK defence firms (Filtronic, Chemring, smaller specialists) trade at lower multiples than Continental European peers. The “UK discount” persists despite the Defence Industrial Strategy and rising spending commitments. Chemring is the clearest example: at 16.6x EV/EBITDA, it trades in line with traditional European primes despite operating in the munitions and countermeasures segment where demand is structurally elevated. A continental acquirer buying Chemring at current multiples is getting munitions exposure at a significant discount to what the same capability would cost inside a re-rated European prime.
Tier-2 and Tier-3 suppliers across Europe who have not yet re-rated. Many SMEs in the defence supply chain are still priced on historical earnings rather than forward order books.
Munitions and ammunition manufacturers, where capacity constraints mean years of earnings visibility but multiples have not fully reflected this.

Where the market is overheated:

Re-rated names (Rheinmetall at ~31-34x, Saab at ~35x) are priced for perfection. Traditional primes (Leonardo at 14x, Thales at 17.6x, BAE at 20.3x) offer more moderate entry points but less leverage to the re-rating story. Any disappointment on contract timing, margin delivery, or geopolitical de-escalation would trigger correction.
Defence AI start-ups at unicorn+ valuations (Helsing at €12bn, Quantum Systems at €1bn+) are priced on potential, not current earnings. These valuations assume successful transition from venture to scaled defence contractor, which historically has a high failure rate.
Deutsche Bank explicitly warned in January 2026 that European defence stocks may be near peak valuation.

Key judgement: The sector overall is trading at 40-60% above five-year historical averages. This is partially justified by genuinely structural demand increases, but a correction of 15-25% is a realistic possibility if any of the risk factors in Section 7 materialise. Confidence in a correction occurring within 18 months: realistic possibility (35-45%).

Probability and confidence estimates throughout this paper are the author’s analytical judgements based on the factors cited. They are not model outputs.

One structural factor not visible in any of these multiples: the SAFE regulation (Security Action for Europe, €150bn in EU procurement loans) has introduced an eligibility requirement that directly determines whether a target company can access the largest pool of new defence contracts in a generation. A non-EU acquisition of a SAFE-eligible company can destroy the order book value on day one of closing. See Section 5 for the full analysis.

Private equity has reached the same conclusion about where the entry points are.

4. PRIVATE EQUITY: WHO IS ACTIVE AND WHAT ARE THEY BUYING?

Active PE Firms in European Defence

Tikehau Capital — Tikehau Défense et Sécurité (TDS), €150m initial (partners: SocGen Assurances, CNP Assurances, CARAC). Strategy: dual-use, primary/secondary/co-invest, evergreen structure (99yr, ELTIF 2.0). Broader A&D fund raising €800m, backed by Airbus, Safran, Thales.

CVC Capital Partners — Dedicated defence team being built. Size not disclosed. Strategy: European defence industrials. Early stage of strategy pivot.

Weinberg Capital Partners — Eiréné Fund, €215m (closed above target). Strategy: French defence and security SMEs and mid-caps. Focus on French industrial base.

Marondo Capital — Fund II, targeting €250m. Strategy: dual-use defence and critical infrastructure SMEs. Munich-based, founded 2016. German Mittelstand focus.

EIF / InvestEU — Defence Equity Facility (DEF), €175m (€100m EDF + €75m EIF). Strategy: defence innovation ecosystem, venture and growth. Committed €50m to Join Capital Fund III (deeptech/dual-use).

General Catalyst, Lightspeed, Accel — Via direct investments. Strategy: defence tech venture. Investors in Helsing.

Balderton Capital — Via direct investments. Strategy: defence tech venture. Led Quantum Systems €160m round.

PE Market Dynamics

PE defence deal value in Europe hit $790m in 2025 (4.8x year-on-year). Venture deal volume has nearly quadrupled over five years. Target IRRs: 18-25% net, with the thesis that long-term government contract visibility provides downside protection while sector re-rating provides upside. ESG barriers are dissolving: defence is now investable for institutional LPs who previously excluded it. This shift appears structural, though it remains contingent on sustained political consensus.

The constraint is deal flow, not capital. Many high-quality assets are either too small for large PE funds or already valued at levels that compress returns. Confidence: almost certain PE activity doubles by end of 2027.

The cross-border dynamics governing all of this are changing faster than most deal teams have updated their models.

5. CROSS-BORDER DYNAMICS

“Buy European” Preferences

The political shift is unmistakable. The ReArm Europe programme and the EU Commission’s Defence Readiness Omnibus are explicitly designed to channel procurement towards European suppliers. Key dynamics:

ITAR avoidance is now a selling point. ITAR (International Traffic in Arms Regulations) is the US export control regime governing defence technology transfers. EU Commissioner Kubilius has publicly stated that ITAR is “becoming a problem.” European firms are actively marketing their products as “no China, no Russia, no ITAR.” This is creating a structural preference for European-origin solutions.
€800bn ReArm Europe programme explicitly prioritises European industrial capacity. US contractors are being frozen out of significant tranches of European procurement (Courthouse News, March 2026).
Procurement thresholds rising: the Defence and Sensitive Security Procurement Directive threshold is increasing to €900,000, which will affect the volume of contracts subject to competitive EU-wide tendering.

FDI Screening

A revised EU FDI screening regulation is under negotiation, targeting effectiveness by end of 2027.
France has already blocked US acquisitions of defence suppliers on national security grounds, and conditionally approved others with state influence mechanisms.
Germany’s screening regime has tightened significantly since 2020, with defence-adjacent acquisitions now routinely reviewed.
UK position: the National Security and Investment Act (2021) gives the government broad intervention powers. The UK has been more permissive than France but is tightening.

SAFE: The €150bn Eligibility Problem

Confidence level: CONFIRMED

The Security Action for Europe (SAFE) instrument (Regulation EU 2025/1106, entered into force 29 May 2025) is the most consequential new variable in European defence M&A. SAFE provides up to €150bn in long-maturity loans to member states for joint military procurement. As of April 2026, 19 member states have been approved for allocations ranging from Poland’s €43.7bn to Cyprus’s €1.18bn. The programme was oversubscribed: total national requests exceeded €150bn. First loan payments are expected April 2026.

SAFE’s M&A relevance is structural, not incidental. To access SAFE-funded contracts, companies must meet all of the following eligibility criteria:

Establishment: legally established in EU, EEA/EFTA, or Ukraine.
Executive management: management located in EU/EEA/EFTA/Ukraine, not third countries.
Third-country control: prohibited unless FDI screening mitigation measures are in place.
Component origin: maximum 35% of total component value from outside EU/EEA/EFTA/Ukraine.
Design authority (Category 2 only): the EU entity must be able to define, adapt, and evolve the design independently of any third-country entity.

The design authority rule is the most commercially significant. Category 2 covers drones, AI, electronic warfare, air and missile defence, and strategic enablers: the highest-growth segments in the sector. Any company where a non-EU parent controls the IP or can restrict code modifications to an EU subsidiary is locked out of this category regardless of where the subsidiary is incorporated. This directly affects US-owned European subsidiaries operating under tightly controlled IP licensing agreements.

The M&A consequence is direct. Any acquisition of a SAFE-eligible European defence company by a non-EU buyer risks disqualifying that company from SAFE-funded contracts on day one of closing. The valuation premium embedded in a SAFE-eligible order book disappears with the change of control. UK companies face a specific additional complication: the UK has not concluded a SAFE participation agreement as of April 2026, with UK industry describing the terms on offer as unattractive. Until this is resolved, UK-to-European acquisitions face a structural eligibility risk that intra-EU deals do not.

This is the kind of structural risk that does not appear in a Bloomberg screen or a standard due diligence checklist. If you are advising on a cross-border acquisition in European defence, reply directly to admin@theinterlock.org.

The JV as Structural Solution

Confidence level: CONFIRMED

The joint venture has emerged as the dominant vehicle for European defence consolidation, and SAFE reinforces every reason why. Four structural pillars explain the pattern:

1. State ownership blocks full exits. France holds significant stakes in Thales. Italy holds stakes in Leonardo and Fincantieri. Naval Group is over 60% French state-owned. Governments will not approve full acquisitions of strategic assets. Article 346 TFEU gives member states an explicit legal right to exempt defence transactions from EU internal market rules on national security grounds. Golden share mechanisms (government-retained special rights that allow a state to block or veto changes of control in strategic companies; Italy’s “golden power” rules are particularly broad) apply to acquisitions of control. They do not typically apply to JVs where no single party acquires decisive control.

2. SAFE and EU funding rules reward JVs. EDF, EDIP, and SAFE all require multi-national consortia with EU ownership, EU management, and EU-based IP. A JV structured with majority EU governance, EU-domiciled IP holding entity, and EU executive management satisfies SAFE’s eligibility tests. A full acquisition by a non-EU buyer destroys them.

3. ITAR creates national firewalls. Decades of transatlantic technology transfer mean much of European defence technology contains US-origin ITAR-controlled components. Full cross-border acquisitions concentrate ITAR liability and can trigger mandatory US State Department review. JVs allow each national entity to retain its own ITAR-controlled technology within its own legal perimeter, with controlled interfaces to the shared entity.

4. Workshare politics demand domestic content. Parliaments will not approve major procurement contracts unless domestic industry captures a meaningful share of production and employment. JVs with formal workshare agreements are the political mechanism that makes cross-border cooperation viable.

The major recent JVs:

MBDA — Airbus (37.5%) / BAE Systems (37.5%) / Leonardo (25%). Established 2001, ongoing. Full European missile portfolio. National subsidiaries preserved throughout. The template.

KNDS — KMW (Germany) / Nexter (France) 50/50. Established 2015, IPO 2026. Land systems holding structure. Subsidiaries remain legally separate.

LRMV — Leonardo / Rheinmetall 50/50. Oct 2024. Italian MBT, AICS armoured vehicles. Italy gets 60% of physical work.

Edgewing (GCAP) — BAE Systems / Leonardo / JAIEC (33/33/33). June 2025. GCAP: Global Combat Air Programme, UK-Italy-Japan 6th-generation fighter. Design and delivery beyond 2070.

Project Bromo — Airbus / Thales / Leonardo (35/32.5/32.5). Oct 2025 MOU. European space champion. €6.5bn revenue, 25,000 employees.

Rheinmetall-MBDA Naval Laser — Rheinmetall / MBDA Germany. Q1 2026. Naval laser weapons for the German Navy.

The FCAS failure is the warning. GCAP succeeded as a JV because workshare and IP were divided equally from day one with no design authority dispute. FCAS (Future Combat Air System, the rival France-Germany-Spain programme), where France retained design authority asymmetrically and Germany refused to fund 30% of the programme for 0% of the IP, is described as in a “fatal tailspin” as of February 2026, with the demonstrator aircraft yet to begin work and the operational date having slipped from 2040 to 2045. The lesson: JVs succeed when governance, workshare, and IP ownership are agreed upfront. They fail when design authority is contested after the framework agreement is signed.

The forward trajectory. Bain’s 2026 analysis projects that “joint ventures are likely to mature into deeper integrations or full mergers as the programme matures.” Today’s JV is tomorrow’s M&A target, once political conditions for full consolidation develop. KNDS’s dual IPO is the clearest example of this trajectory in motion.

Implications for Deal Flow

Intra-European M&A is facilitated. The political environment favours European-to-European consolidation. This benefits Rheinmetall, Leonardo, Thales, and Saab as acquirers.
US-to-European acquisitions face increasing friction. Not blocked outright, but subject to conditions, especially in France and Germany. US PE firms may face particular scrutiny.
UK is the swing factor. Post-Brexit, the UK sits outside the EU framework but maintains Five Eyes relationships. UK firms can be acquired by both US and European buyers, making them attractive “bridge” assets.
ITAR-free supply chains are a premium. Companies that can demonstrate ITAR-free capability chains command higher valuations and face fewer cross-border barriers.

Confidence: almost certain that “buy European” preferences intensify through 2027. Highly likely that FDI screening becomes more restrictive, not less.

5.5 THE IRAN CONFLICT: SECOND-ORDER EFFECTS ON THE M&A THESIS

Updated 8 April 2026: A ceasefire between Iran and Israel was announced on 8 April 2026, on day 39 of the conflict. The ceasefire is pending negotiations and regional instability is expected to continue. It is not a peace agreement. The analysis below reflects this update: the conflict is paused, not resolved, and the medium-term demand signals it generated remain intact.

How the Conflict Supports the Demand Case

Munitions consumption — Status post-ceasefire: active depletion pauses, but does not reverse. 39 days of conflict accelerated depletion of European and US stockpiles already drained by Ukraine. Stockpile rebuild remains urgent. The under-supply argument is reinforced, not weakened, by a pause that leaves inventories depleted.

Air defence demand — Status post-ceasefire: validated, procurement decisions locked in. Iranian missile and drone capability provided a real-world stress test for integrated IAMD systems. IRIS-T (German short-range air defence), SAMP/T and Aster (Franco-Italian medium-range systems) performance data is now in procurement dossiers across European defence ministries. Orders already triggered do not reverse on ceasefire. Positive read-through for MBDA, Diehl, Rheinmetall, Thales remains.

Strategic autonomy as survival — Status post-ceasefire: partially softens near-term, structurally unchanged. Strait of Hormuz risk premium eases with the ceasefire. The immediate survival framing softens. But the underlying argument, that European energy security depends on defence industrial autonomy, is embedded in policy frameworks that predate the conflict and will outlast it.

Drone and counter-drone validation — Status post-ceasefire: permanent, not conflict-dependent. Shahed-class drone performance data is on record regardless of ceasefire. The loitering munition procurement thesis is validated. Helsing, Quantum Systems, Tekever, and Milrem retain the benefit.

ISR and space demand — Status post-ceasefire: eases near-term, structurally supported. Real-time satellite coverage in contested airspace was a live procurement driver during the conflict. ISR (intelligence, surveillance, and reconnaissance) demand eases with the ceasefire but the capability gap it exposed remains. Project Bromo and Iceye theses intact.

How the Ceasefire Changes the Complications

Capacity diversion — Eases materially. European primes surging product to the Middle East theatre can redirect capacity to Ukrainian stockpile rebuild and domestic orders. Execution risk on existing order books reduces.

US attention — Partially frees for Ukraine. This is the most significant change for the M&A thesis. Trump administration bandwidth previously absorbed by active conflict now partially returns to Ukraine negotiations. Given Trump’s stated desire for a Ukraine deal, this increases the probability of a Ukraine settlement in the near term. See revised probability below.

Oil price and macro — Should ease, positive for financing. Hormuz disruption risk premium should partially unwind. Lower energy prices ease inflation pressure and improve the ECB and BoE rate path. Financing costs for PE-backed acquisitions improve at the margin.

Supply chain — Normalises. Shipping insurance costs should ease. Gulf supply chain disruption risk reduces.

Political bandwidth — Releases for EU priorities. EU member state attention can return to the FDI Screening Regulation and Defence Readiness Omnibus. Both should now progress faster.

Net Judgement (Updated 8 April 2026)

The conflict was a net positive for the structural M&A thesis. The ceasefire resolves the execution complications without reversing the demand signals. Supply chains normalise, financing conditions improve, and EU political attention returns to the defence industrial agenda. The structural case is cleaner post-ceasefire than during active conflict.

The key risk the ceasefire introduces: Ukraine correction probability revises upward. The rationale for revising the Ukraine settlement probability down to 20-25% on a 6-month horizon was that an active Iran war absorbed US diplomatic attention and hardened European threat perception. That logic now partially reverses. With US bandwidth freed and continued regional instability rather than escalation, a near-term Ukraine settlement is more likely than it appeared on 7 April. The 6-month correction probability revises from 20-25% back to approximately 28-33%. This remains below the original pre-Iran estimate of 30-40% because continued Middle East instability keeps threat perception elevated in Europe. The 18-month probability is broadly unchanged.

Confidence: highly likely (75-85%) that the demand signals generated by the conflict translate into accelerated European IAMD and munitions procurement regardless of ceasefire. Realistic possibility (28-33%) that a Ukraine settlement triggers a 15-25% valuation correction within 6 months.

6. RISKS: WHAT COULD DERAIL THE M&A BOOM

Ukraine ceasefire / peace deal
Impact: could reduce urgency and trigger 15-25% valuation correction in defence stocks. Iran ceasefire (8 April 2026) frees US diplomatic bandwidth for Ukraine, increasing near-term probability. Probability: realistic possibility (28-33% on 6-month horizon; 35-45% on 18-month horizon). Watch: Trump administration signals, Zelensky position, NATO summit communiqués.

Valuation correction
Impact: Deutsche Bank warned Jan 2026 that stocks may be near peak. A correction could freeze M&A as bid-ask spreads widen. Probability: likely within 18 months (55-65%). Watch: Rheinmetall and Saab share prices as leading indicators. Any earnings miss will be punished severely at current multiples.

Execution risk
Impact: converting pledges to signed contracts takes years. Semiconductor shortages, skilled labour shortages (cleared engineers, welders, electronics technicians at 12-18 month hiring lead times), and raw material constraints create a hard ceiling on output growth that order books and revenue models do not capture. Probability: highly likely that execution falls short of market expectations (75%). Watch: actual contract awards vs. announced spending. Monitor delivery timelines, workforce announcements, and supply chain signals from Rheinmetall, BAE, MBDA.

Political change
Impact: a shift in government in France, Germany, or the UK could alter procurement priorities. Far-right or far-left governments may redirect spending or impose different industrial preferences. Probability: unlikely to reverse trend, but realistic possibility of disruption (25-35%). Watch: 2027 French legislative cycle, German coalition stability.

Interest rate / financing risk
Impact: higher-for-longer rates increase the cost of PE-backed acquisitions and reduce leveraged buyout returns. Elevated by Iran-driven energy price and inflation risk. Probability: realistic possibility (30-40%). Watch: ECB and BoE rate decisions through 2026.

Integration failure
Impact: large JVs (LRMV, Project Bromo, KNDS) are complex multi-national structures. Cross-border European defence consolidation has a consistent track record of governance dysfunction and missed timelines (EADS, Eurofighter, FCAS). Probability: realistic possibility (30-40%). Watch: governance disputes, work-share disagreements, timeline slippage.

Trump administration / transatlantic friction
Impact: US tariff threats on European exports, F-35 dependency politics, NATO Article 5 ambiguity, and potential US export restrictions on European primes selling to third markets. Probability: realistic possibility (35-45%). Watch: US tariff announcements, NATO summit outcomes, F-35 programme reviews.

The Bear Case

Before stating the net assessment, it is worth running the strongest counter-argument. The following is not the author’s view but is the case a serious sceptic would put:

1. The pledge-to-contract gap is historically enormous and the market has not priced it. European defence procurement has a multi-decade record of announced spending dramatically exceeding contracted spending. Germany’s Zeitenwende (the historic policy shift announced by Chancellor Scholz in 2022, declaring a fundamental change in German defence and foreign policy) €100bn special fund took two years to translate into meaningful orders. If pledged ReArm Europe spending converts at historical rates, current order book extrapolations are wrong. At 30-40x EV/EBITDA, Rheinmetall is priced for near-perfect conversion, which has no historical precedent in European defence.

2. Re-rating, not earnings, has driven returns. Most of the 2023-2026 return in European defence equities has come from multiple expansion, not earnings growth. Re-rating regimes that take three years to build can unwind in six months.

3. Capacity does not arrive when ordered. Building munitions plants, certifying suppliers, and qualifying components takes three to seven years. Companies that have promised capacity ramps in 18-24 months will largely miss. When they do, multiples compress.

4. Consolidation history in European defence is poor. Cross-border European defence consolidation has a consistent track record of governance dysfunction and missed timelines. EADS, MBDA governance, the Eurofighter programme, and the ongoing FCAS tensions are all precedents. Project Bromo and LRMV will encounter the same forces.

5. Defence is a political asset class and political consensus is fragile. The current consensus is built on Ukraine, Trump’s NATO scepticism, and generalised threat perception. Two of those three factors could change within 24 months.

Author’s net response to the bear case: The structural drivers are more resilient than the bear case suggests: European rearmament is embedded in constitutional frameworks (Germany’s debt brake reform), treaty obligations (NATO 2%), and industrial policy (ReArm Europe). But current valuations assume execution rates that European defence has not historically achieved. The key investment call in 2026-2027 is differentiating companies with signed contracts from those with indicative order books.

Key Judgement on Risk

The most likely scenario is a partial correction rather than a collapse. The structural drivers are politically durable. But current valuations assume near-perfect execution of spending plans, which historically does not happen in European defence procurement.

The Interlock will track the KNDS IPO, the Chemring watch list, and any shift in Project Bromo antitrust conditions as leading indicators. Subscribe to follow this as it develops. If you disagree with the bear case, or have visibility on mandates not reflected here, reply and tell me why.

FOR NON-DEFENCE CORPORATE BOARDS: SECOND-ORDER IMPLICATIONS

European rearmament affects companies that have nothing to do with defence. Four implications worth a board conversation:

Engineering talent and supply chain competition. European defence primes are hiring cleared engineers, electronics technicians, and precision manufacturers at scale. If your business competes for the same talent or components, expect tighter markets and higher costs. The sector’s 12-18 month hiring lead times for qualified personnel are not unique to defence. Action required: HR and procurement teams should benchmark salary ranges and component lead times in relevant specialisms now, before the competition intensifies further. This is a workforce planning issue, not a background risk.

Dual-use reclassification. Technologies in cyber, AI, satellite communications, advanced materials, and autonomous systems are being reclassified as strategically sensitive. Assets your firm holds, licenses, or depends on may become subject to new export controls, FDI screening, or government intervention rights. Action required: commission a review of your IP and technology assets against the EU Defence Readiness Omnibus and UK National Security and Investment Act. This is a multi-month legal and IP review. If you have not started it, you are already behind the curve.

ESG policy shift. If your investment policy or supply chain standards previously excluded defence-adjacent companies, the political consensus has shifted beneath you. Several major institutional investors have already reversed exclusions. Action required: assess whether your ESG frameworks still reflect stated risk appetite. This is a board-level governance question, not a procurement one.

Energy and logistics exposure. The Iran-Israel conflict and Strait of Hormuz disruption risks have eased following the ceasefire announced 8 April 2026, but the underlying vulnerability is structural, not resolved. Any business with material Middle East supply chain exposure should have scenario analysis in place for renewed disruption. The ceasefire is a pause, not a settlement. Action required: if you have not run a Hormuz disruption scenario in the last 12 months, do it now while conditions are calm.

KEY SIGNPOSTS TO MONITOR

Ukraine ceasefire agreement reached — Likely 15-25% sector correction. Procurement continues but urgency drops. Political will tested.
KNDS IPO delayed beyond Q3 2026 — Signals Franco-German political friction or market concerns about defence valuations.
Project Bromo antitrust conditions imposed — Could fragment the European space consolidation thesis.
Rheinmetall share price drops >20% — Leading indicator of broader sector correction. Would widen bid-ask spreads and slow M&A.
New EU FDI regulation agreed — Would clarify, and likely tighten, the rules for cross-border defence M&A.
UK defence spending reaches 2.6% of GDP on schedule — Confirms the demand thesis for UK defence SMEs.
Major defence programme cancellation (any country) — Would signal that spending pledges are softer than markets assume.
PE fund closings exceed targets — Confirms capital availability thesis. Watch Tikehau’s €800m A&D fund and Marondo Fund II.

CONFIDENCE SUMMARY

European defence M&A activity increases significantly in 2026-2027: highly likely (75-90%)
Valuations remain elevated but correction risk is material: highly likely that some correction occurs (75-90%)
PE activity in European defence doubles by end 2027: almost certain (>90%)
“Buy European” preferences intensify: almost certain (>90%)
UK mid-cap defence firms are acquired: highly likely (75-90%)
Project Bromo proceeds to completion: highly likely (75-85%), though conditions likely
KNDS IPO proceeds in 2026: highly likely (75-85%)
Ukraine ceasefire triggers correction within 6 months: realistic possibility (28-33%) — revised up following Iran ceasefire freeing US diplomatic bandwidth
Advisory mandates in defence M&A grow significantly: almost certain (>90%)

The question was never whether to be in this space. It is whether current multiples have already priced in execution that European defence procurement has never actually delivered. The structural case is sound. The valuation discipline is not. The investors and advisers who separate those two things will do well. The ones who conflate them will not.
