Leonardo's Helicopters Division Just Got a New Boss. The Business Report Tells a Different Story.

When Leonardo named Stefano Villanti as managing director of its Helicopters Division on September 2nd, the headlines tracked leadership continuity. Villanti spent the last decade in senior rotorcraft roles at Leonardo, most recently running sales, marketing, and contracts. He replaces Gian Piero Cutillo, who led the division since 2017 and was promoted to co-general manager at the group level earlier this year. Smooth succession on the surface.

But if you're here because a headline mentioned Leonardo and wondered whether the stock is still interesting, the leadership change isn't what matters. What matters is what Leonardo's factor profile looks like compared to the rest of European defense — and the numbers say the market has not yet finished re-pricing this company.

Here's the comparison set.

The cheapest defense multiple with the fastest earnings growth

European defense stocks have re-rated dramatically over the past five years. The broader European defense basket — Leonardo, Thales, Rheinmetall, BAE, Safran, Dassault, Rolls-Royce — has seen its enterprise-value-to-next-twelve-months revenue multiple expand by roughly 365% since 2020, far outpacing the US defense basket's 192% expansion. The multiple expansion reflects a structural shift: European governments are finally treating defense spending like a budget item that stays, not one that cycles.

Inside that basket, Leonardo is an outlier.

As of late July 2026, Leonardo trades at a trailing P/E of roughly 25x, Thales at 34x and Rheinmetall at 69x. The price-to-book gap is wider still: Leonardo at 3.3, Thales at 6.4, Rheinmetall at 9.6. On price-to-sales, Leonardo sits at 1.6 compared with Thales at 2.3 and Rheinmetall at 5.3.

That looks like Leonardo is the cheap one. The question is whether cheapness here reflects a real discount or whether the business simply doesn't deserve a premium.

The earnings trajectory answers that.

Leonardo's adjusted net result surged 74% year-over-year in the first half of 2026, reaching €476 million. Organic revenue grew 8% and EBITA grew 26%, both across all business segments. New orders in the first half produced a book-to-bill ratio of 1.6x, and the total order backlog climbed to approximately €59 billion — a 30% year-over-year increase. The company now sees more than two and a half years of revenue visibility.

Even more telling is what management just did with guidance. At the H1 results in late July, new CEO Lorenzo Mariani upgraded the full-year 2026 outlook: orders raised to €28.2 billion, EBITA to €2.21 billion, and free operating cash flow to €1.37 billion. The company's 10% return-on-sales target — previously set for 2027 — is now projected to be reached one year early.

A company that raises its growth and margin guidance mid-year while trading at the lowest multiple in its peer set is not being punished by the market. It's being ignored. That distinction matters because it means the gap between price and fundamentals is not yet bid away.

What the leadership shuffle actually means

The Villanti appointment comes at the end of a turbulent leadership year. In April, the Italian government — Leonardo's largest shareholder with a 30% stake — replaced CEO Roberto Cingolani with Lorenzo Mariani, a former Leonardo commercial director who most recently ran MBDA's Italian operations. The move triggered a shareholder revolt; activist investor Guy Wyser-Pratte pushed an alternative board slate, and Norway's sovereign wealth fund signaled opposition. The government's list won by a single point: 50.1% to 49.5%.

Cingolani's ouster was reportedly strategic, not performance-based. Sources suggest the government wanted a sharper focus on traditional weapons manufacturing — missiles, armored vehicles, "nuts and bolts defense" — amid wars in Ukraine and the Middle East, rather than Cingolani's push toward cybersecurity, digitalization, and non-kinetic systems. Mariani, described by industry observers as a "safe choice" who knows the military customer base and requires no learning curve, fits that mandate.

For an investor, the leadership sequence — Cutillo promoted, Villanti installed, Mariani leading the group — reads less like disruption and more like consolidation. The people moving into these roles all have deep Leonardo tenures. Cutillo built the Helicopters Division from €3.2 billion in revenue in 2017 to €5.8 billion in 2025. Villanti managed its commercial function for the past three years. Mariani was Cingolani's number two before leaving for MBDA.

The continuity argument is reinforced by what Cingolani himself said on his last day as CEO: "The strategy is built, capitalized and contracted. The job now is execution, not strategy."

Whether execution under Mariani will match Cingolani's pace is the open question. The first data point, though, is positive — Mariani's first act was to raise guidance, not renege on it.

The IDV acquisition and what it does to the balance sheet

One number that shifted during H1 deserves attention: net debt rose 49% year-over-year to €3.2 billion. The driver was Leonardo's €1.6 billion acquisition of Iveco Defence Vehicles in March, adding land-based armor and platforms to Leonardo's portfolio and creating a consolidated IDV-OTO Melara consortium.

The debt increase is real but contextual. Leonardo's debt-to-equity ratio sits at 0.47 — below Thales's prior levels and in line with the European defense median. Interest coverage is 6.1x. The company raised €1.37 billion in free operating cash flow for 2026, enough to service and gradually reduce the incremental leverage from IDV.

More importantly, the IDV acquisition changes Leonardo's business mix. Before the deal, Leonardo was heavily weighted toward helicopters, defense electronics, and aerostructures. Land defense was a gap. After IDV, Leonardo becomes a more complete European defense OEM — capable of integrating platforms, sensors, electronics, and software across air, land, and cyber. That matters because European customers are increasingly demanding integrated systems rather than standalone hardware.

Where the stock sits for a portfolio

Here's how to think about Leonardo right now, without pretending to know where the stock price ends up.

The valuation factor is the clearest piece of the puzzle. At roughly 25x trailing earnings and 23x forward earnings, Leonardo trades meaningfully below Thales, Rheinmetall, and the broader European defense average. The forward P/E gap is especially relevant because Leonardo's earnings are growing faster than its peers — EPS was up 14% trailing twelve months, and the H1 adjusted net result growth of 74% suggests acceleration, not deceleration.

The growth factor is confirmed by the guidance revision. Raising orders, EBITA, and FOCF targets in the same quarter is a signal that management sees favorable momentum continuing. A backlog of €59 billion with a 1.6x book-to-bill ratio makes that projection credible, not optimistic.

The profitability factor is turning. The 10% return-on-sales target, now one year ahead of schedule, reflects margin expansion across all segments — not just one-time items or accounting adjustments. EBITA grew 26% on 8% organic revenue growth, meaning margins are widening at roughly 140 basis points of incremental operating leverage per quarter.

The momentum factor is neutral-positive. Leonardo's shares are up roughly 17% year-to-date, near but below their 52-week high of €66.26. The stock has not rallied into the guidance revision the way it did in early 2026, which suggests the factor story hasn't been fully priced in yet. The dividend yield of roughly 1.1% is below average, but that's consistent with a company reinvesting in growth rather than distributing cash.

The safety factor is adequate but not outstanding. Net debt of €3.2 billion is manageable given €1.37 billion in projected free cash flow and interest coverage above 6x, but the IDV integration adds execution complexity. Debt-to-equity at 0.47 is healthy but deserves monitoring as the company continues investing in capacity and joint ventures.

The judgment

Leonardo is not 27% undervalued, nor is it fully valued. Those are the kinds of numbers that look precise and say nothing. What the factor stack shows is a European defense company with the lowest valuation multiple in its peer set, the fastest earnings acceleration, and upgraded guidance — priced as though the market hasn't finished processing the trend.

The leadership changes are real. Mariani is untested as CEO of Leonardo, and his mandate to refocus on traditional defense products could mean strategic shifts from Cingolani's technology-forward approach. But the people he's working with — Cutillo at co-GM, Villanti at Helicopters, the broader team Cingolani built — have institutional memory that makes an abrupt course change unlikely.

For a portfolio, Leonardo fits the quality-growth sleeve in a European defense position. It offers exposure to structural rearmament without the valuation stretch of Rheinmetall or the multiple compression risk of Thales. The specific trigger that would change this assessment is not a single earnings miss or a leadership reshuffle — it's a sustained breakdown in the guidance-to-results relationship. If Mariani raises guidance again and then fails to deliver, the multiple discount is justified. Until then, the factor stack says Leonardo is still catching up to where the business has moved.
