Lockheed Martin earns a Buy as record backlog, missile-defense demand, and raised 2026 guidance offset leverage and F-35 execution risk. The stock trades below consensus value, but balance-sheet pressure keeps the rating from turning more bullish.
Lockheed Martin (LMT) earns a Buy rating for a moderate-risk, medium-term portfolio. The investment case rests on three concrete facts: Q3 2026 sales rose 11% year over year to $20.7B, backlog reached a record $292.0B, and management raised 2026 sales, EPS, and free cash flow guidance for the second consecutive quarter.
The growth engine is shifting toward missiles, interceptors, radar, space defense, and sustainment. Missiles and Fire Control sales increased 24% year over year in Q3 2026, while Aeronautics sales increased 13%. The company also holds a structural position in the F-35, missile defense, classified space programs, and integrated command systems.
The main restraint is financial leverage and uneven historical profitability. Debt reached $21.7B at year-end 2025, debt to equity stood at 3.2x, and net margin fell from 10.2% in 2023 to 6.7% in 2025. At a quoted share price of $549.29, LMT trades below the analyst consensus target of $618.86, but the balance sheet and program execution risks prevent a stronger rating.
Lockheed Martin (LMT) is a Bethesda, Maryland-based aerospace and defense contractor founded in 1912. The company employs approximately 123,000 people, including about 72,000 engineers, scientists, and information technology professionals.
LMT sells aircraft, missiles, missile defense systems, helicopters, radar, command-and-control systems, satellites, space transportation systems, cyber solutions, and sustainment services. Its principal customers are the U.S. government, allied governments, and foreign military customers purchasing through the U.S. Foreign Military Sales program.
The business is organized into four segments: Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space. The 2025 revenue mix was $30.3B from Aeronautics, $14.5B from Missiles and Fire Control, $17.3B from Rotary and Mission Systems, and $13.0B from Space.
The company reported $77.0B of trailing revenue, a 10.5% year-over-year revenue growth rate, and a $127.3B market capitalization in the core valuation snapshot. Its scale creates a broad platform for large government programs, but it also ties results to procurement timing, contract terms, and program execution.
Aeronautics remains LMT's largest business, representing 40.3% of 2025 revenue. Q3 2026 Aeronautics sales reached $8.2B, up 13% from $7.3B in Q3 2025, while operating profit increased 9% to $743M. F-35 production and sustainment drove the increase, supported by C-130 activity.
Management's 2026 Aeronautics outlook calls for $31.1B to $32.5B of sales and $2.92B to $2.95B of operating profit. The outlook also incorporates lower margins from scaling new F-35 contracts and absorbing F-16 and C-130 challenges. This segment offers the largest revenue base, but it also carries the greatest single-program concentration.
Missiles and Fire Control is the strongest current growth contributor. Q3 2026 sales increased 24% to $4.5B and operating profit increased 24% to $631M. PAC-3, THAAD, GMLRS, and PrSM production volumes drove the result. The 2026 outlook calls for $17.25B to $17.45B of sales and $2.395B to $2.425B of operating profit.
Rotary and Mission Systems produced Q3 2026 sales of $4.5B, up 3%, and operating profit of $524M, up 4%. Higher radar and command-and-control volume supported the segment. Management's 2026 outlook calls for $17.7B to $18.0B of sales and $1.88B to $1.90B of operating profit.
Space generated Q3 2026 sales of $3.5B, up 4%, with operating profit of $331M. Next-generation interceptor and fleet ballistic missile activity supported the segment, while lower National Security sales tied to the OPIR program lifecycle and reduced ULA equity earnings constrained profit. The 2026 outlook calls for $13.95B to $14.05B of sales and $1.38B to $1.40B of operating profit.

The F-35 is LMT's flagship product and its largest program. The F-35 generated 27% of consolidated 2025 sales and 67% of Aeronautics sales. Management described it as the only in-production fifth-generation fighter in the free world, and Q3 2026 Aeronautics growth included higher F-35 production and sustainment volume.
The F-35 franchise combines aircraft production with training, logistics, upgrades, repairs, and long-term sustainment. That installed base gives LMT a revenue stream beyond initial aircraft deliveries. The Q3 2026 presentation also identified F-35 production and sustainment as the primary driver of the segment's $31.1B to $32.5B full-year sales outlook.
The product's scale also creates risk. F-35 lots 20 and higher were still under negotiation in the research context, and the company identified advance-acquisition costs for Lot 20 as a pressure point. LMT's Aeronautics outlook also carries lower margins while new F-35 contracts scale, making execution as important as demand.
The wider flagship portfolio includes PAC-3, THAAD, GMLRS, PrSM, hypersonic systems, Aegis integration, and directed-energy weapons. These programs connect LMT's aircraft franchise to the faster-growing missile defense and precision-strike categories.
LMT's innovation advantage is rooted in systems integration rather than a single laboratory breakthrough. In the Q2 2026 transcript, CEO James Taiclet described the company's approach as connecting existing battle-tested systems to address new missions. The counter-UAS solution tested at Yuma Proving Ground moved from concept to live-fire testing in under 45 days.
The company is applying that integration model to PAC-3 within the Aegis Combat System, hypersonic glide bodies, autonomous systems, radar, and counter-drone technologies. LMT also received a government contract for a transportable 500-kilowatt laser tied to cruise-missile and drone defense.
Production technology is part of the competitive advantage. Management cited AI-driven equipment analytics, predictive maintenance, machine-learning quality checks, open architecture, and autonomous manufacturing infrastructure. These investments support speed and scale, two factors that the 2026 defense market is assigning greater importance to.
LMT is expanding production capacity in response to its backlog. The company opened a missile assembly building in Cortland, Alabama, broke ground on an 87,000-square-foot munitions production center in Troy, Alabama, and continued work on a Titusville, Florida facility supporting the Trident II missile.
The company invested $876M in capital assets and research and development during Q2 2026. Full-year 2026 capital expenditure guidance stands at $2.1B to $2.3B in the October update. LMT also signed an agreement to acquire Ultra Maritime, adding undersea sensing and autonomous sea-drone capabilities.
The January 29, 2026 10-K identifies rare earth minerals, aluminum, titanium, specialty steel, carbon fiber, and advanced microelectronics as important inputs. It also cites supplier disputes, regulatory restrictions, inflation, extended lead times, and parts shortages as factors that have increased costs and affected program performance.
LMT's workforce adds operating depth, with 123,000 employees, approximately 93% located in the U.S., and roughly 19% covered by collective bargaining agreements. The company hired nearly 10,800 employees in 2025 and created internships for 2,000 students.
The market backdrop favors LMT's missile defense, precision fires, space, radar, and command-and-control exposure. MarketsandMarkets estimates the integrated air and missile defense market at $37.9B in 2025 and $68.4B by 2030, representing a 12.5% CAGR. The same research places defense cybersecurity growth at an 11.2% CAGR through 2031.
Grand View Research estimates the global air defense systems market will rise from $46.9B in 2023 to $67.9B by 2030, a 5.4% CAGR. Its missile market estimate rises from $73.7B in 2026 to $93.6B in 2030, a 7.7% CAGR.
Mordor Intelligence estimates the U.S. aerospace and defense market at $463.1B in 2026 and $610.2B in 2031. The U.S. defense market estimate is $354.5B in 2026 and $423.9B in 2031. These figures place LMT inside a large market with faster growth in the specific categories where its Q3 backlog and new awards are concentrated.

The U.S. government generated 72% of LMT's 2025 sales, while international customers generated 28%. The customer base includes all branches of the U.S. military, NASA, allied governments, and foreign military customers purchasing through U.S. government channels.
Customer demand is visible in the Q3 2026 backlog of $292.0B and the 4.0x book-to-bill ratio. The Q2 2026 backlog was $230.0B, including a seven-year, $35.0B missile defense award designed to quadruple interceptor production. The Q3 backlog also included $52.5B tied to the PAC-3 MSE multi-year award.
The customer relationship is durable because LMT systems require certification, interoperability, training, logistics, and lifecycle support. That structure is visible in the F-35 production and sustainment model, Japan's radar shipset deliveries, and the proposed European PAC-3 maintenance facility involving the United States, Germany, the Netherlands, Poland, and Sweden.
LMT's January 2026 10-K names Boeing (BA), General Dynamics (GD), L3Harris Technologies (LHX), Northrop Grumman (NOC), and RTX (RTX) as primary competitors. The filing also identifies smaller competitors, startups, nontraditional defense contractors, and non-U.S. companies.
LMT's advantages are most visible in fighter aircraft, missile defense, integrated sensors, space systems, and large multi-domain programs. The company cites technical excellence, reliability, safety, cost competitiveness, program execution, customer confidence, and global accessibility as important competition factors.
Competition is intensifying in autonomy, artificial intelligence, electronic warfare, additive manufacturing, robotics, advanced materials, and commercial access to space. LMT's investments in open architecture, AI-enabled production, counter-UAS systems, and autonomous maritime systems address those areas, but new entrants retain an advantage in speed and specialized software development.
Defense budget priorities are moving toward munitions, drones, counter-UAS, autonomy, missile defense, space, cyber, and industrial-base expansion, according to Deloitte's 2026 aerospace and defense outlook. Those priorities align directly with LMT's Q2 and Q3 awards in interceptors, radar, hypersonics, directed energy, and space-based defense.
The macro opportunity is strongest in integrated air and missile defense. MarketsandMarkets projects that market to grow from $37.9B in 2025 to $68.4B in 2030. LMT's PAC-3, THAAD, radar, Aegis integration, and next-generation interceptor programs give the company direct exposure to that expansion.
The macro risk is government dependence. Budget delays, continuing resolutions, acquisition policy changes, contract terminations, and shifting national priorities can affect delivery schedules and revenue recognition. The 2026 10-K also states that government contracts can be terminated for convenience or default, with recovery determined by the contract terms and performance history.
Debt reached $21.7B at year-end 2025 and debt-to-equity stood at 3.2x, leaving leverage as the main constraint on an otherwise improving defense franchise.

Get Full Access →Lockheed Martin (LMT) enters the medium-term period with stronger demand evidence than its recent five-year margin history. Q3 2026 sales grew 11%, backlog reached $292.0B, MFC sales grew 24%, and management raised the full-year outlook again.
The stock is not a flawless compounder. Debt to equity is 3.2x, the current ratio is 1.09, F-35 concentration is significant, and historical earnings include several sharp misses. Still, the combination of missile-defense demand, the F-35 sustainment franchise, rising analyst EPS estimates, and an 8.0% free cash flow yield supports a disciplined Buy rating at the current quoted price.
