Melrose Industries: Navigating Geopolitical Shifts to Unlock Aerospace and Defense Growth

The aerospace and defense sector has long been a haven for industrial resilience, but in 2025, it's more than just a safe harbor—it's a high-conviction growth story. Melrose Industries, the UK-based aerospace giant, is capitalizing on structural tailwinds from geopolitical tensions, defense spending surges, and its own transformational strategy to unlock a business model that's both high-margin and undervalued. For investors seeking exposure to a company with a unique blend of operational discipline, technological differentiation, and cash-flow resilience, Melrose is worth a second look.

Structural Growth: Defense Spending and Order Backlogs Drive Momentum

The first half of 2025 has already delivered a masterclass in strategic execution for Melrose. The company reported adjusted operating profit of £310 million, outpacing analyst estimates by £11 million, and reaffirmed its revenue guidance of £3.55 billion to £3.70 billion. This performance is underpinned by a structural shift in global defense spending. NATO and European allies have committed to increasing defense budgets in response to rising geopolitical tensions, creating a surge in demand for aerospace suppliers. Melrose's deep integration into both civil and defense aerospace markets—through its ownership of GKN Aerospace—positions it to benefit from this dual tailwind.

Defense spending alone is a $2.4 trillion global market in 2025, with Europe's share growing at a 12% CAGR since 2022. Melrose's 50% North American revenue exposure (its largest market) is complemented by a strong European footprint, making it a “geopolitical hedge” that thrives in both peacetime and conflict. The company's order backlog for defense platforms has reached record levels, ensuring multi-year visibility. Meanwhile, the civil aerospace sector is rebounding from pandemic-related disruptions, with narrow-body aircraft demand driving 11% revenue growth in Melrose's Engines division.

Technological Differentiation: RRSPs and Additive Fabrication as Moats

Melrose's true competitive edge lies in its business model. The company's Risk and Revenue-Sharing Partnerships (RRSPs) with engine manufacturers like Pratt & Whitney, GE, and Rolls-Royce create a “cash-flow machine” that's rare in industrial sectors. These long-term contracts split the risks and rewards of engine production and maintenance. For Melrose, this means:
- High-margin structural components (engine casings, turbine mounts) that don't require costly maintenance.
- Lifelong cash flows from 19 RRSPs, with £22 billion in projected net cash inflows and a net present value of £5.7 billion.

The company's focus on non-moving engine parts is genius. While competitors juggle costly service contracts, Melrose earns a cut of maintenance fees without bearing the labor or logistical burden. This structure is why its Engines division is expected to generate 70% of the company's profits by 2025, with target operating margins of 28%.

But Melrose isn't resting on its RRSPs. The company is pioneering Additive Fabrication (AF), a 3D printing technology that reduces material waste and enables complex geometries in aircraft structures. GKN Aerospace, now part of Melrose, has been developing AF for over two decades and is the only firm with AF components in operational aircraft. The industrialization of this technology—backed by a £50 million investment in Sweden—could deliver a 20%+ IRR, further widening its moat.

Transformational Momentum: Tariff Mitigation and Free Cash Flow Expansion

Melrose's ability to adapt to geopolitical headwinds is a testament to its operational agility. U.S. tariffs on aerospace parts initially threatened its North American operations, but the company mitigated exposure through supply-chain restructuring and pricing negotiations. CEO Peter Dilnot's team deserves credit for turning a potential crisis into a strategic advantage.

The results are clear: free cash flow has surged to over £100 million in 2025, with projections of £600 million by 2029. This cash flow is being reinvested into the business (e.g., AF expansion) and returned to shareholders via a buyback program and a growing dividend. Melrose's leverage ratio has dropped to 1.7x, and its deleveraging path is on track to achieve investment-grade status.

Why This Is an Undervalued Opportunity

Despite its robust fundamentals, Melrose trades at a discount to its intrinsic value. The company's RRSPs alone justify a valuation premium, as they represent a cash-flow stream with characteristics of a utility (predictability) and a tech company (innovation). Yet its current market cap lags behind the £5.7 billion net present value of its RRSPs.

The U.S.-UK and EU trade agreements, which include aerospace exemptions, add another layer of optimism. These deals reduce regulatory uncertainty and create a stable environment for Melrose's cross-border operations. Meanwhile, its exposure to next-generation engines (e.g., CFM's RISE project) positions it to lead the transition to hydrogen and sustainable aviation fuels—a $500 billion market by 2040.

Investment Thesis: Buy and Hold for Long-Term Value

Melrose Industries is a rare blend of structural growth, technological leadership, and operational discipline. Its ability to navigate geopolitical risks while expanding margins and cash flow makes it a compelling long-term hold. For investors, the key metrics to watch are:
- RRSP cash-flow generation (track quarterly updates on net present value).
- Free cash flow expansion (target £600 million by 2029).
- Additive Fabrication adoption (monitor industrialization progress and IRR).

With defense spending surging, civil aerospace rebounding, and a business model designed for compounding cash flows, Melrose is a “buy and forget” candidate for the high-margin aerospace sector. This is not a stock for short-term noise—it's a long-term bet on a company that's building the engines of the future.
