Lockheed Martin vs RTX: Valuation and Backlog Gap

Lockheed Martin and RTX remain the two largest pure-play U.S. defense primes, but they present materially different balance-sheet and valuation profiles on key metrics as of early April 2026. Lockheed Martin (LMT) reported a backlog of approximately $160 billion in its 2025 10-K, compared with an estimated $95 billion backlog at RTX (RTX) consolidated after the Raytheon integration, according to company filings and secondary reporting (SEC filings, Dec 31, 2025; Yahoo Finance, Apr 5, 2026). Market valuations also diverge: Lockheed's trailing P/E and dividend yield are roughly 15.0x and 2.6% respectively, versus an implied 18.5x P/E and 2.1% yield for RTX on the same date (Yahoo Finance, Apr 5, 2026). Investors and corporate strategists are weighing these differences against near-term revenue growth (LMT +4% YoY, RTX +1% YoY in 2025) and free-cash-flow profile disparities that have widened since 2023. This article presents a data-driven comparison, contextualizes the drivers behind the gap, and assesses implications for sector allocations and corporate strategy without offering investment advice.

Context

The defense sector has been operating with a mix of steady base demand and episodic surge spending tied to geopolitical flashpoints; primes with larger fixed-price programs and long-duration airframe contracts typically show higher backlog-to-revenue ratios. Lockheed Martin has historically derived a larger proportion of revenue from platform programs—F-35 sustainment and new aircraft deliveries—while RTX's revenues are more diversified across aero engines, missiles, and avionics following the 2020 merger and later portfolio reshaping. That structural difference explains why, as of Dec 31, 2025, Lockheed's backlog-to-2025 revenue ratio was around 2.3x versus roughly 1.1x at RTX (company 10-Ks; Yahoo Finance summary, Apr 5, 2026).

Macro policy continues to matter: the U.S. defense budget baseline has grown in nominal terms over the last three fiscal years, supporting a multi-year procurement pipeline. Export approvals and allied procurement cycles further amplify demand for certain programs—Lockheed’s F-35 remains central, with foreign military sales supporting backlog durability. RTX benefits from engines and integrated systems that have faster replacement and aftermarket cycles, producing a steadier revenue cadence but lower long-duration backlog. These demand characteristics are central to the observed valuation and cash-flow differences between the two names.

Finally, capital allocation histories diverge. Lockheed has maintained a steady dividend and share-repurchase cadence, while RTX has prioritized deleveraging and reinvestment after its major M&A and integration phases. That has influenced market perceptions of near-term earnings quality and multiple expansion potential for each company (SEC filings and investor presentations, 2024–2026).

Data Deep Dive

Backlog and revenue: Lockheed's reported backlog of approximately $160 billion (10-K, Dec 31, 2025) provides multiyear revenue visibility: at the company's 2025 revenue run-rate of about $70 billion, that backlog equates to roughly 2.3 years of revenue coverage. RTX's backlog, reported around $95 billion on the same reporting basis, covers approximately 1.1 years against an estimated $88 billion revenue base in 2025 (company disclosures; Yahoo Finance, Apr 5, 2026). This gap explains why Lockheed's revenue visibility is being priced differently by markets, with the backlog concentrated in large platform programs that generate long-duration sustainment streams.

Valuation and cash flows: As of April 5, 2026, market-implied valuations show Lockheed trading at a trailing P/E near 15.0x and a dividend yield of ~2.6%, while RTX trades at a higher trailing P/E of ~18.5x and yields ~2.1% (Yahoo Finance, Apr 5, 2026). Free cash flow (FCF) margins differ materially in 2025: Lockheed generated approximately an 8% FCF margin, compared with RTX’s nearer-term 5–6% FCF margin after integration and higher working-capital intensity on certain commercial aerospace products (company cash-flow statements, 2025). When adjusting for capital expenditures and pension obligations, Lockheed's balance sheet presents a lower net debt-to-EBITDA profile on a normalized basis.

Profit drivers: program mix drives margin variability. Lockheed benefits from higher mix of fixed-price, high-contribution sustainment work that produces more predictable gross margins once ramped. RTX's margins are affected by cyclical commercial aerospace repair-and-overhaul activity and variable aftermarket economics; its missile and defense segments carry higher margin potential but represent a smaller share of consolidated revenue. In 2025, Lockheed reported operating margin expansion of about 120 basis points YoY, while RTX's consolidated margin was essentially flat, according to company earnings releases and filings (Q4 2025 results; company statements).

Sector Implications

Program concentration risk versus diversification is the primary trade-off for institutional allocators. Lockheed’s concentrated exposure to platform programs like the F-35 creates a headline risk—programme-specific delays or foreign-policy shifts can disproportionately affect revenue—yet that same concentration underpins durable backlog and aftermarket revenue. RTX’s diversified exposure across engines, avionics, and integrated systems smooths revenue cyclicality but reduces the multi-year visibility that investors prize in defense names at times of geopolitical uncertainty.

From a procurement and supply-chain standpoint, primes with larger backlogs exert more purchasing power with suppliers, potentially preserving margins through inflationary cycles. Lockheed's backlog gives it leverage over multi-year supplier contracts, which in turn contributes to margin resilience in a higher-cost environment. Conversely, RTX's exposure to engine spares and commercial MRO ties its revenue to airline activity and OEM cycles; this can introduce earnings volatility if commercial air travel softens, as happened historically in downturns (industry data, IATA; company disclosures).

Market structure and M&A optionality also play a role. RTX has been actively reshaping its portfolio, which presents both upside via synergies and downside via integration execution risk. Lockheed's M&A activity has been more conservative, focusing on bolt-ons that enhance sustainment or avionics capabilities. For investors evaluating defense allocations, these strategic choices are as material as headline valuation multiples.

Risk Assessment

Execution risk: For Lockheed, program execution on long-duration platforms and supply-chain continuity are principal operational risks. Historically, schedule slips on complex platforms have deferred revenue recognition and pressured margins; similar execution risk at RTX centers on integration of acquired businesses and stabilization of commercial aftermarket segments. Both companies disclose these risks in their annual 10-Ks and regular investor updates (SEC filings, 2025–2026).

Geopolitical and policy risk: changes in U.S. congressional appropriations or international procurement decisions can rapidly reprice future order books. A single large foreign military sale or a change in allied procurement plans could materially alter backlog trajectories over a two- to three-year window. Export licensing and intergovernmental negotiations remain opaque variables that can cause short-term volatility.

Financial and capital-allocation risk: RTX’s post-merger capital structure and prioritization of debt reduction constrain near-term shareholder returns but reduce leverage risk; Lockheed’s willingness to return cash through dividends and buybacks can compress funding optionality for large-capex initiatives. Both firms face pension, long-term warranty, and legacy liabilities that require active management and can influence free cash flow variability under stress scenarios.

Fazen Capital Perspective

Contrary to a consensus that equates larger backlog with automatic outperformance, Fazen Capital views the Lockheed–RTX gap as more nuanced: backlog breadth is valuable for revenue visibility, but quality of backlog—contract type, renewal cadence, and margin profile—matters more for free-cash-flow conversion. A $160 billion backlog concentrated in sustainment and fixed-price platform work will typically convert more predictably than a similarly sized backlog filled with short-cycle commercial aftermarket orders. We therefore place a premium on program-level margin conversion and contractual protection terms rather than headline backlog alone.

In addition, we emphasize liquidity-cycle analysis: companies that can convert backlog into high-quality, repeatable aftermarket revenue and maintain lower working-capital intensity provide superior downside protection in revenue downturns. RTX’s diversification into commercial aerospace can be an advantage in a sustained travel recovery scenario, but in periods of defense-specific demand shocks, Lockheed’s program durability is a structural hedge. This argues for a balanced, scenario-based evaluation of the two names rather than a single-metric tilt.

Lastly, we flag optionality in export markets. Lockheed’s platform franchise offers outsized upside from incremental foreign military sales and sustainment contracts; those are second-order drivers that can materially rerate enterprise value if realized at scale. Monitoring export approvals, DoD sustainment budgets, and allied procurement timetables provides higher signal-to-noise than short-term headline multiples.

Outlook

Near-term, expect continued market attention on quarterly cash-flow reconciliation to backlog, margin guidance for major programs, and management commentary on capital allocation. If Lockheed sustains year-over-year FCF margin improvement—using rough 2025 numbers as a baseline (approx. 8% FCF margin)—the market is likely to ascribe premium visibility to its valuation. For RTX, improvement in commercial aerospace cycles or faster-than-expected integration synergies could compress the multiple differential, but those outcomes depend on operational execution and macro demand recovery.

Over a three- to five-year horizon, secular trends such as increased allied defense spending, extended lifecycle sustainment demand, and avionics modernization programs should support both companies, albeit in different ways. Continuous monitoring of program-level profitability, backlog composition (fixed-price vs cost-plus), and export pipelines will be critical to assessing relative performance. Institutional investors should also track cash returns, net-debt trajectories, and pension funding status as leading indicators of financial flexibility.

FAQ

Q: How have dividends and buybacks differed recently between the two companies?

A: As of company reports through 2025, Lockheed maintained a steady dividend yield near 2.6% and continued modest buybacks, prioritizing stable returns. RTX prioritized deleveraging and reinvestment after major integrations, producing a lower near-term yield (~2.1%) but reduced leverage. This reflects differing capital allocation priorities and should be monitored via quarterly statements for any policy shifts (company releases, 2025).

Q: Has program concentration historically created outsized volatility for Lockheed?

A: Yes—historically, Lockheed experienced episodic volatility from program execution challenges on complex platforms, which can compress margins and delay revenue recognition in a single quarter. However, the multi-year sustainment tail for platforms often moderates long-term revenue impacts; monitoring schedule milestones and foreign order timing helps evaluate that risk.

Bottom Line

Lockheed offers deeper multi-year revenue visibility via a larger backlog and steadier FCF conversion; RTX provides structural diversification and potential upside if commercial aerospace and integration synergies normalize. Institutional assessments should weigh backlog quality, margin conversion, and capital-allocation signal rather than headline multiples alone.
