TKMS Taps Europe’s Defense Boom With Frankfurt IPO

Overview

Warship and submarine builder TKMS tapped Europe’s defense boom with a Frankfurt IPO, delivering a robust debut that underscored investors’ appetite for defense assets. The stock opened strongly and traded well above indicative levels, implying a valuation north of €5 billion on day one. The listing forms the centerpiece of Thyssenkrupp’s spin-off strategy: the industrial group retains 51% while distributing the remainder to existing shareholders, a move intended to unlock value and sharpen focus across the portfolio.

Why this IPO landed so well

Investor enthusiasm reflects the structural re-rating of European defense. Since Russia’s 2022 invasion of Ukraine, governments across the continent have committed to multi-year rearmament programs and faster naval modernization. TKMS, the world’s largest maker of non-nuclear submarines and a leading frigate builder, is a direct beneficiary. Its order backlog has tripled in five years to about €18.6 billion as navies in Germany, Norway and other allies expand undersea and surface fleets. The company also sells underwater systems via the Atlas electronics franchise, widening mission-critical exposure.

Deal mechanics and parent strategy

The Frankfurt IPO arrives amid Thyssenkrupp’s broader restructuring. By separating TKMS while keeping majority ownership, the parent can surface value in a defense pure-play and still participate in its upside. Management has signaled continued simplification of the conglomerate, spanning potential moves in other units, to focus capital where returns are highest. The TKMS Frankfurt IPO also avoids the national-security frictions that complicated past external bids for the asset.

What TKMS brings to the market

Portfolio strength. TKMS builds conventionally powered submarines (including the 212CD class) and blue-water frigates, capabilities that align with NATO priorities on deterrence, sea-lane security, and anti-submarine warfare.
Visibility. The backlog stretches well into the 2030s, cushioning near-term macro swings and giving investors line-of-sight on production ramps and cash-conversion milestones.
Option value. TKMS is competing for large international submarine programs (notably Canada and Poland) that could expand the addressable market.

Valuation and comparables

On debut, TKMS shares jumped, with prints reported around the €80–€87 band during early trading, well above pre-listing talk, placing the equity value above €5 billion and, at peaks, nearer €5.5 billion. That multiple still screens at a discount to certain European defense peers, reflecting program concentration, execution complexity in naval builds, and the continuing majority stake held by the parent. The flip side: if TKMS executes its backlog and captures new export contracts, the discount can narrow.

What investors are watching next

Backlog conversion and margins. Naval programs are multi-year and technically exacting; investors will monitor stage-payments, learning-curve effects, and supply-chain stability (propulsion systems, nav electronics, steel and composites).
Pipeline wins. Success in tenders such as Canada’s non-nuclear submarine program or follow-on European orders could materially lift revenue visibility.
Capital structure and free float. With Thyssenkrupp owning 51%, future liquidity events (secondary sells, buybacks) could broaden the free float and index eligibility over time.
Industrial partnerships. Europe’s naval arena is consolidating—Rheinmetall’s push into surface ships and Fincantieri’s partnerships are notable. TKMS may pursue selective alliances to de-risk bids and scale.

Risks and constraints

Program execution risk. Warship and submarine schedules can slip on design changes, testing bottlenecks, or supplier delays, with knock-on working-capital effects.
Political and export approvals. German export controls and NATO coordination remain pivotal; shifts in coalition policy or public spending priorities could alter timelines.
Competitive pressure. Aggressive moves by European and Asian rivals (including yard integrations and M&A) raise pricing tension and bid complexity.
Cyclicality beyond the super-cycle. While the Europe defense boom looks durable, an eventual fiscal re-prioritization could moderate medium-term growth.

Market read-through

The TKMS Frankfurt IPO adds another data point to an active European defense equity tape, alongside recent listings, carve-outs and asset reshuffles. It signals that investors are willing to underwrite long-dated defense cash flows when programs are funded, geopolitics are supportive, and disclosure improves. Parent-level shares can wobble around spin dates, but value-unlocking transactions are generally rewarded as conglomerate discounts compress.

Bottom line

TKMS taps Europe’s defense boom with a Frankfurt IPO that landed above expectations, validating demand for naval-defense exposure and the logic of the Thyssenkrupp spin-off. With a record order backlog, expanding export opportunities and a clearer equity story, the company arrives public with wind at its back, provided it converts programs on time and on budget. Core theme: Europe’s defense super-cycle is moving seaward, and TKMS aims to be one of its defining beneficiaries.
