European Defense Stocks Navigate Record Valuations and Geopolitical Crosswinds

European defense stocks surge on NATO spending, with KNDS targeting a €20B IPO in 2026 and Rheinmetall posting record profits despite a cautious 2026 outlook.

The European defense sector is experiencing a historic boom, fueled by sustained conflict and renewed NATO spending commitments. This has propelled the STOXX Europe Aerospace & Defence Index to gains exceeding 65% in 2025 alone. The order books of the continent's eight largest defense contractors are expanding by 15%, with collective free cash flow hitting record levels in 2024. Global defense expenditures are projected to climb to $3.6 trillion by 2030.

A notable shift in investor sentiment accompanies this surge. European capital, once withheld from the sector due to ESG considerations, is now reconsidering its stance. This influx has driven valuations to heights that invite scrutiny: European defense equities now trade at forward price-to-earnings multiples near 30, placing them in a league with technology titans like Microsoft and Nvidia. The industry is thus characterized by a tension between powerful structural tailwinds and increasingly ambitious market pricing.

KNDS: Europe's Next Major Defense IPO Gathers Momentum

While not yet publicly traded, the German-French Leopard tank manufacturer KNDS is intensifying preparations for an initial public offering slated for summer 2026. The company is targeting a valuation of approximately €20 billion.

Operational momentum supports this ambition. In 2024, KNDS secured new orders worth €11.2 billion, swelling its total order backlog to €23.5 billion. Revenue increased to €3.8 billion. Recent contracts underscore robust demand: Lithuania ordered 44 Leopard 2A8 tanks for €700 million, and the German Bundeswehr is planning a framework agreement for up to 500 MARS 3 multiple rocket launchers.

The company has appointed Lazard as an advisor for the listing, with a dual listing in Frankfurt and Paris under consideration. KfW, alongside JPMorgan, is exploring an anchor investment to secure German government influence. Strategically, a new KNDS subsidiary has commenced operations in Ukraine, focusing on artillery ammunition production and maintenance for systems like the Caesar howitzer. Since 2023, the workforce has grown by 5,000. The appointment of Christian Schulz, former CFO of Renk, to the supervisory board highlights the seriousness of the IPO preparations.

Rheinmetall: Stellar Earnings Met with Profit-Taking

As the undisputed benchmark for European land defense, Rheinmetall posted formidable 2025 results. Revenue advanced 29% to €9.94 billion, while operating profit jumped 33% to €1.84 billion. The operating margin expanded from 15.2% to 18.5%, and the order backlog ballooned to €63.8 billion.

Despite these records, the market reaction was subdued, with shares falling roughly 8% on the report. The decline was triggered by a 2026 revenue forecast of €14.0 to €14.5 billion, which fell short of the Bloomberg consensus estimate of approximately €15 billion. The stock currently trades near $375 on U.S. exchanges, about 6% below its 50-day moving average.

Strategically, the group is expanding its portfolio. The acquisition of shipbuilder NVL extends maritime capabilities, and the company is positioning itself as a supplier for replenishing American missile stocks amid the Iran conflict. Analyst consensus points to a fair value near $2,115, implying upside potential exceeding 30%. A key question remains whether the order backlog will indeed rise to an anticipated €135 billion this year.

Renk: Record Orders Contrast with Cautious Outlook

The specialist for gearboxes and drive systems reported strong 2025 figures: revenue of €1.4 billion marked a 20% increase. Adjusted earnings per share rose 38% to €1.42, with the dividend slated for a proportional hike to €0.58. The order backlog reached a record €6.68 billion.

The cautious forward guidance tempered enthusiasm. The revenue forecast of at least €1.5 billion for 2026 sits about 3% below consensus. The adjusted EBIT guidance also missed expectations by approximately 2%. Shares trade around €56, more than 36% below their October 2025 52-week high. Renk's CEO noted the war in Iran could provide additional demand stimulus.

Deutsche Bank analyst Christophe Menard maintains a price target of €72. The 14-analyst consensus average is €68.46. Bullish arguments center on the European rearmament wave and the record backlog, while skeptics focus on the conversion speed of orders into revenue. A €200 million order volume deferred into 2026 is under particular scrutiny.

Axon Enterprise: AI-Powered Growth Confronts Lofty Valuation

Axon occupies a unique niche within this group. As the only U.S.-listed company without traditional weapon platforms, it focuses on body cameras, Tasers, and AI-powered software for law enforcement. Its business model relies on recurring SaaS revenue, bolstered by legislative mandates for body cameras in many U.S. states.

Fourth-quarter results were exceptional: quarterly revenue of $796.7 million represented growth of 38.5%. Adjusted EPS of $2.15 significantly surpassed the consensus estimate of $1.60. For 2026, management targets revenue of up to $3.61 billion.

Valuation remains the central debate. With a normalized P/E ratio above 75 and a price-to-sales ratio of 15.3, Axon is the most highly valued stock in this selection. Corresponding volatility is high, with an annualized 30-day figure of 72%, well above European peers. The share price of around €425 is over 43% below its 52-week high. Insider sales by CEO Rick Smith and the chief accounting officer in March have added to investor caution. Analysts, however, maintain a median price target of $802.50 and a buy rating.

Airbus: Caught Between Defense Tailwinds and Supply Chain Headwinds

Airbus faces a dichotomy. Its defense division shows positive momentum: Airbus Helicopters was selected by the European Defence Agency for a multi-mission drone program, and the CAPA-X platform is being expanded. However, in the far larger commercial aviation business, a conservative delivery forecast of only 870 aircraft for 2026 has dampened sentiment.

The share price has suffered, trading near €171. This places it almost 12% below its 50-day moving average and over 22% below its January 2026 52-week high. Persistent engine and avionics shortages continue to constrain delivery rates, with Barclays estimating only 75 deliveries for Q1 2026.

Q4 2025 earnings provided a silver lining: EPS of €2.92 beat expectations of €2.45 by 19%. The analyst consensus remains decidedly bullish, with a median price target of €219.55. Not one of the 15 covered analysts recommends selling. The next test arrives on April 28 with the Q1 results.

Sector Outlook: A Unified Megatrend with Divergent Paths

These five companies represent the breadth of the defense sector, and their recent performance reveals significant differentiation behind the shared macro trend:

• Rheinmetall, while the fastest grower, also trades at the richest valuation among European peers with a trailing P/E over 83. Its shares have gained 540% in three years.
• Renk offers the largest discount from its high (over 36%) but has yet to fully convert its record backlog into revenue.
• Airbus struggles under the dual pressure of conservative commercial aircraft guidance and supply chain issues. Its defense unit is benefiting but cannot fully offset the commercial headwinds.
• KNDS eludes direct comparison for now. Its target valuation implies a price-to-sales ratio of about 5.3 based on 2024 figures—an ambitious level supported by its €23.5 billion backlog.
• Axon operates in a distinct niche. Its SaaS model provides predictable revenue, but its valuation is elevated even for a growth stock.

The ongoing conflict in Iran, now in its 18th day, remains a focal point. The closure of the Strait of Hormuz—the world's most critical oil trade route—fundamentally distinguishes this escalation. A ceasefire could trigger short-term rotation out of defense stocks, while a prolonged conflict would further strengthen the structural demand argument.

Near-term catalysts are clearly defined: Rheinmetall's Q1 order intake and potential naval contracts from the F126 and F127 programs (worth around €12 billion) are in focus. The timeline for KNDS's IPO will be shaped by market conditions and the potential KfW stake decision in May and June. Renk must demonstrate progress on converting deferred orders in its first-half results. Airbus reports next on April 28, and Axon continues to work toward its strategic goal of $6 billion in revenue by 2028.

The overarching assessment remains clear: governments are directing capital toward infrastructure, defense, and strategic sectors. Fund managers and analysts expect defense to remain a dominant investment theme for the rest of the year. The risk of a faster-than-expected de-escalation is real, but budgets are already allocated and contracts signed. The structural story for this sector extends far beyond the next ceasefire.
