RTX's Germany Deal Confirms The Cash Flow Inflection Nobody Priced In

The State Department's Foreign Military Sales approval is the US government's formal green light for the transaction. It is not yet a signed contract. The $11.9 billion headline covers combat system elements split between Lockheed Martin (PAC-3 missiles, related sustainment) and RTX (radar, command and control integration, and follow-on munitions). Industry analysts estimate RTX's share of the package at roughly 35-45%, or between $4.2 billion and $5.3 billion in booked orders over the next three to five years.

Germany is the largest single European defense buyer and has committed to 2%-plus of GDP on defense spending through 2030. The Zeitenwende, the strategic pivot announced after Russia's invasion of Ukraine, is in its fourth year and the multi-year order book is only now translating into large award decisions. Poland, Denmark, and the Nordics have followed similar procurement paths. RTX's European backlog is already at roughly $19 billion and climbing.

The Patriot Missile franchise, which anchors RTX's European defense posture, has become the most in-demand air defense system on the planet. Production constraints have capped near-term deliveries. The Germany order is largely a 2027-2029 revenue stream, with cash flowing a year earlier in the form of progress payments.

RTX has returned roughly $8 billion a year to shareholders through buybacks and dividends during the Powder Metal disruption. The capital return programme continued even while free cash flow was pressured, funded partially from balance sheet cash and partially from working capital pulls. Total debt sits at $43 billion against $9 billion in cash. The leverage profile is comfortable but not pristine.

Here is what changes in a $7.9 billion FCF world growing into a $9-11 billion FCF world. Management can fund three things simultaneously: dividend growth at 7-9% annually, roughly $5 billion in annual buybacks, and the mid-single-digit capex growth needed to unlock the European production expansion. The precision of that capital allocation math is what separates RTX from its defense peers right now.

Compare to Lockheed Martin, whose FCF sits at roughly $6 billion against a heavier capex cycle for F-35 modernisation. Compare to General Dynamics, whose mix of defense and business jets produces more cyclical cash flow. RTX, with Collins Aerospace on commercial aftermarket and Pratt & Whitney past the powder metal cash drag, is now the most balanced cash flow engine in the sector. The Capital Desk views this as a structural advantage, not a cyclical one.

The Patriot PAC-3 missile, produced by Lockheed with RTX radar integration, has moved from 350 units a year in 2021 to a committed production ramp of 650 units annually by 2027. That is not a capacity constraint being addressed by a capex cycle. It is a capacity constraint being addressed by a capex cycle plus supplier network buildout plus workforce training plus three new facilities. Production expansion in defense is measured in four-year cycles, not quarters.

The chokepoint has implications. RTX's radar and command-and-control systems are backlogged by years. Every additional Patriot order, whether from Germany or Poland or Japan, compresses delivery timelines for the next buyer. That scarcity dynamic is what is driving gross margin expansion on the defense side. Order book growth plus capacity-constrained delivery equals pricing power.

The Capital Desk has tracked this dynamic across three prior defense cycles. The last time a prime contractor had this level of backlog concentration in a single premium franchise was Lockheed with F-35 in 2014-2016, and the multiple re-rated from 14x forward earnings to 21x over that window. RTX's Patriot concentration is not quite as extreme, but the setup rhymes.

Across three complete European defense cycles, the pattern is always the same. Geopolitical shock drives a budget authorisation surge. Approvals lag budgets by eighteen to twenty-four months. Cash conversion lags approvals by another twelve to eighteen months. The full cycle takes three to five years to translate from political speech to prime contractor cash flow.

The last textbook case was post-9/11, when US defense budgets surged 65% between 2001 and 2007. Raytheon's free cash flow grew from $1.1 billion in 2001 to $2.6 billion by 2007, and the stock appreciated 180% across that window while the S&P 500 compounded at roughly 4% a year. The current European cycle is smaller in absolute budget terms but more concentrated in RTX's core product franchises. Patriot, NASAMS, AIM-9X, and Evolved Sea Sparrow are all in order-book overflow.

Historically, defense primes have outperformed by roughly 8-10 percentage points annually in the middle innings of European procurement surges. We are in the middle innings now. The Germany approval is the marker.

Collins Aerospace and Pratt & Whitney still generate the majority of RTX's revenue, and the commercial aftermarket is a separate cash flow story from the defense thesis. Global air traffic, measured by revenue passenger kilometres, passed pre-pandemic levels in mid-2024. Aircraft utilisation rates are at decade highs. The higher the utilisation, the more aftermarket spares and service revenue flows to the engine and systems providers.

Collins revenue grew approximately 9% in FY2025, with the aftermarket component growing closer to 14%. Pratt commercial engine sales grew 16% as the GTF powered-down fleet steadily returned to service. The margin profile on aftermarket is materially higher than OEM; aftermarket gross margins sit north of 35% versus OEM at low double digits. Mix is the quiet tailwind.

By comparison, GE Aerospace's commercial aftermarket is benefiting from the same dynamics, but GE has a narrower commercial engine portfolio concentrated on CFM LEAP. RTX's diversification across narrow-body, wide-body, and regional jets provides cushion against any single programme disappointment. The Capital Desk prefers the diversification at this stage of the cycle, even if it comes with slightly lower peak-to-peak operating leverage.

Operating income expanded to $8.9 billion in FY2025, up 32% year over year. Operating margin moved to 10.0%, still well below defense peer Lockheed at 12.5% but improving. The gap closes as the Pratt Powder Metal fleet work winds down and the commercial aftermarket normalises. A two-point margin expansion on $90 billion of revenue is $1.8 billion of incremental operating profit. That alone adds roughly $1.20 to EPS at the current share count.

The enterprise value sits at roughly $300 billion against $17 billion of trailing EBITDA, or 17.6x. That multiple is elevated versus defense sector history, which typically trades at 12-14x EV/EBITDA. The premium is justified only if FCF conversion sustains above 100% of net income for a multi-year window. The Germany deal provides the visibility for that outcome.

Analyst consensus target price sits at $216, about 7% above the current $201 share price. That target has not fully digested the Germany approval or the follow-on European orders that are likely in calendar 2026. Our internal model supports a $230-245 fair value range on trough cash conversion assumptions and $260-275 on peak assumptions. The market is paying for mid-case. We think it should pay for upper-case.

On enterprise value to backlog, RTX trades at roughly 1.7x versus Lockheed at 1.5x and Northrop at 1.2x. The premium reflects RTX's larger commercial aerospace exposure, which the market values at a higher multiple than pure defense. On a sum-of-the-parts basis, Collins alone is arguably worth $80-90 billion as a standalone commercial aerospace systems business, or $2,500 of book-value-equivalent per $1 of Collins revenue. Pratt is harder to value given the in-progress powder metal remediation but floor-case is $40-50 billion.

That leaves the defense business valued at roughly $140-150 billion on a sum-of-parts basis, against $40 billion in defense revenue, or 3.5x revenue. Lockheed Martin trades at 1.9x defense revenue. The premium is either justified by RTX's faster growth rate in defense or it is overdone. The Capital Desk views current levels as fairly priced given faster growth, but sensitive to any slippage on European conversion rates.

The more telling peer is BAE Systems, the European prime benefiting from the same Zeitenwende tailwind. BAE trades at 16x forward earnings against RTX's 29x. The gap reflects US capital market preferences more than fundamental growth differentials. If the European rearmament narrative persists into 2027, the gap narrows. If European growth proves cyclical rather than structural, the gap widens. We favour the structural read.

Three data points would change the RTX capital allocation thesis. First, a decision by management to accelerate buybacks above the current $4-5 billion annual pace. That would signal internal confidence in cash conversion that exceeds our model and argue for upper-case fair value. Second, a European conversion rate that falls below 70% from announced approvals to signed contracts. That has not happened yet, but procurement processes are noisy and any slippage matters.

Third, and most importantly, a large acquisition. RTX completed the Collins-Raytheon merger in 2020 and has been digesting that integration for five years. Management has flagged that the integration phase is now complete and the next capital allocation discussion is more open. A $10-15 billion acquisition in the defense electronics or space systems adjacency would be constructive if it funded organic growth; it would be concerning if it fills a product gap the company cannot close organically.

None of these three outcomes is currently in the base case. The working assumption is continuity on capital allocation, steady European order conversion, and incremental margin expansion. If any of those change materially, the thesis needs to be rewritten. The desk reserves the right to update.
