TKMS vs. Leonardo: A Submarine Pure-Play Takes On Europe's Defence Generalist

TKMS offers naval focus and margin upside at a rich multiple; Leonardo counters with scale, cash flow and a wider valuation cushion.

Two very different ways to own Europe's rearmament trade are on offer. One is a lean, underwater-focused specialist; the other is a sprawling aerospace and defence ecosystem spanning jets, helicopters, electronics and missiles. TKMS and Leonardo both ride the same tailwind of rising European defence budgets, yet they arrive at it from opposite directions — and the market is pricing that difference sharply.

At the heart of the comparison is a valuation gap that says as much about risk appetite as it does about fundamentals. TKMS trades at 5.1 times book value, a "naval premium" that assumes its margin catch-up story plays out. Leonardo, by contrast, changes hands at 1.46 times sales, a multiple that leaves more room for disappointment. The question for investors is whether TKMS's runway justifies the richer multiple, or whether Leonardo's cash generation offers the safer entry into the sector.

A pure-play with momentum under water

TKMS has spent its post-spin-off life accelerating an operational overhaul, and the numbers are starting to show it. Revenue climbed 19% to EUR 1.89 billion in the first nine months of fiscal 2025/26, while adjusted EBIT rose 13% to EUR 110 million. Management recently lifted its margin guidance to 6.5% from 6.0%, a signal that the exit from low-margin legacy work is taking hold. The nine-month margin averaged 5.8%, leaving a clear path toward a medium-term target of 7.0%.

The company's technological lead in non-nuclear submarines — the HDW Type 212 and 214 families — underpins high-margin, large-scale orders. Its global reach was on display with the September 2026 handover of the submarine INS Drakon to the Israeli Navy, alongside its selection as preferred partner for Canada's patrol submarine program. At its Wismar yard, production is being geared toward the F127 frigate program, a move that positions TKMS as a potential consolidator of a fragmented European naval industry.

That said, the specialist carries the risks of its focus. Free cash flow ran negative to the tune of EUR 204 million over nine months, and the order book leans heavily on a handful of large projects.

Leonardo's breadth as a buffer

Leonardo's strength lies in not depending on any single program. In July 2026, management raised full-year guidance, targeting EBITA of EUR 2.21 billion and a 10.0% revenue margin. The diversified model throws off the kind of reliable cash flow that pure-play specialists rarely match, and it supports a dividend yield of 1.28% — an argument for conservative investors who want exposure to European rearmament without the volatility of a single-segment bet.

The strategic moat is built on participation in flagship European programs such as the GCAP fighter jet project and a quarter stake in missile maker MBDA. First-half 2026 orders jumped 40% to EUR 16.3 billion, driven mainly by defense electronics and the helicopter business. The spring 2026 integration of Iveco Defence Vehicles further strengthened land defense, adding EUR 0.67 billion in new orders in the most recent quarter alone.

Leonardo is not without blemishes. It must still turn around its loss-making aerostructures division, and it faces uncertainty over leadership continuity following the departure of former CEO Roberto Cingolani. The new management team under Lorenzo Mariani has secured a record order backlog, but the market is watching closely to see how smoothly new technologies are integrated. Dependence on the Italian state budget is another overhang.

Partnerships are redrawing the map

The competitive landscape is shifting toward cooperation. In early September 2026, TKMS and Fincantieri announced plans to build a cooperation framework in the underwater segment by year-end. The move is designed to offset the scale advantages of global giants and could be the first building block of a formal naval merger.

TKMS has been busy on other fronts too. On September 25, it signed a memorandum of understanding with the EDGE Group to explore joint development of integrated underwater surveillance and protection capabilities — part of a broader defense and security cooperation initiative agreed between the German government and the United Arab Emirates. Operational momentum also came from abroad: roughly a week earlier, subsidiary TKMS ATLAS UK won a contract from the British Ministry of Defence for the Next Generation Countermeasure torpedo defense system for Royal Navy submarines. The project, run in cooperation with Babcock International Group, safeguards 80 jobs in the UK, though the parties declined to disclose the exact contract value.

What the Street is watching

Analysts have lent support to the TKMS story. On September 18, Stifel's Thomas Mordelle initiated coverage with a Buy rating and a EUR 105 price target. Bernstein, for its part, reaffirmed its Outperform rating about two weeks earlier.

The stock has been steadier than its peers. On a recent Friday it changed hands at EUR 80.70, up 0.5%, bringing its year-to-date gain to 22%. That resilience stood out on Tuesday, when German defence names came under pressure — Renk, Rheinmetall and Hensoldt all retreated alongside TKMS, according to a dpa-AFX report. There was no company-specific trigger for the TKMS decline; the pullback reflected a broad consolidation across the sector rather than any operational deterioration. The fundamental news flow for the naval specialist remains anchored in its strategic projects.

Clarity on the full picture arrives at year-end. TKMS publishes its annual financial report on December 7, 2026, when investors will see how the recent partnerships and contract wins translate into final full-year figures.

Two paths, one sector

The comparison comes down to a trade-off between scale and specialization. TKMS offers striking order visibility, a pure naval focus and aggressive margin expansion — offset by a demanding valuation, negative free cash flow and concentration risk. Investors betting on maritime security and a possible sector consolidation will find the more promising specialist here.

Leonardo counters with broad segment diversification, robust operating cash flow and a dominant role in European air defense. Its weak spots are the persistent losses in aerostructures, questions over management continuity and reliance on the Italian state budget. For those seeking a core defence holding in 2026, Leonardo offers more scale, profitability and recurring income.

On balance, the edge goes to Leonardo, carried by superior cash generation and a wider valuation cushion. TKMS remains the riskier but potentially higher-returning wager on the consolidation of Europe's naval defence industry. Which strategy prevails will hinge above all on how the Fincantieri cooperation actually takes shape.
