L3Harris Technologies is a major defense and aerospace company that builds the radios, sensors, and rocket engines used by the United States military. It generated $21.32 billion in revenue over the last twelve months, reflecting a significant expansion following its acquisition of rocket-motor maker Aerojet Rocketdyne. The company has moved from being a provider of tactical communications to a "prime" contractor capable of bidding on the most complex national security projects.
The investment thesis on L3Harris is that it is successfully transitioning from a collection of parts into a single, high-margin defense powerhouse by integrating its recent acquisitions. By owning both the systems and the propulsion that powers them, L3Harris can win larger contracts that were previously reserved for the industry's biggest players.
We think L3Harris is in a strong position to grow as global defense spending rises and the company gets better at making money on its massive order book. The business has built-in protection because its products are designed into military platforms that will be used for decades. What would worry us is any significant delay in major satellite or missile programs.
L3Harris stock climbed steadily over the last few years but recently hit a speed bump. While the company has spent years building a massive defense powerhouse by acquiring rocket and missile makers, its share price has fallen back lately as investors pause to see if these big projects pay off. The business is currently focused on expanding its factories to supply the military.
What does it do?
L3Harris Technologies is a mature defense contractor that earns money by designing and building high-tech electronics, communication systems, and rocket propulsion for military and government use. The company operates as a "Trusted Disruptor," meaning it tries to move faster than older defense giants while maintaining the scale to handle massive projects. Revenue flows from long-term government contracts, often lasting five to ten years. These contracts are typically either "fixed-price," where the company manages costs to keep the profit, or "cost-plus," where the government pays for development costs plus a set fee.
Where does revenue come from?
L3Harris earns the majority of its revenue from four segments focused on space, intelligence, and tactical communications. The Space & Airborne Systems unit builds sensors and satellite electronics, while Integrated Mission Systems provides surveillance platforms. Communication Systems delivers secure tactical radios used by soldiers, and the Aerojet Rocketdyne segment manufactures the rocket motors that power missiles and space launch vehicles. Geographically, about 75% of sales come from the United States government.
Revenue Breakdown
Revenue by Geography
Who are its customers?
L3Harris serves the United States Department of Defense, international allied governments, and major aerospace companies. Its primary customer is the U.S. government, which accounts for the vast majority of its $32 billion order backlog. The company also supports more than 100 international allies who buy tactical radios and surveillance equipment. In its space business, it serves agencies like NASA and commercial satellite operators. L3Harris reported $7.2 billion in new orders in its most recent quarter, demonstrating that demand from these high-budget customers remains steady regardless of broader economic shifts.
What gives it staying power?
The company has staying power because its technology is embedded into critical military platforms that cannot be easily replaced. Once L3Harris radios are chosen for a battlefield network or its engines are built into a missile, the "switching costs" are massive. New competitors face years of regulatory testing and security clearances to even bid.
Where is it headed?
Management is focused on the "LHX NeXt" program, which aims to cut $1 billion in annual costs while making the company more agile. This involves simplifying the organization after years of mergers and focusing on high-growth areas like satellite constellations and missile defense. If successful, it will turn a high-revenue defense business into a much more profitable one.
The single most important trend is the steady acceleration in revenue and order growth following the Aerojet acquisition. Total revenue reached $21.32 billion in 2025, and a book-to-bill ratio of 1.4x in the latest quarter shows that new orders are arriving faster than the company can bill them. This provides a long runway of visible growth for the next several years.
Cash quality is high as free cash flow is projected to grow to $2.68 billion by 2026. The company is consistently converting more of its net income into cash, which is a sign that its business model is efficient. While heavy spending on research and development is necessary to keep its edge, the underlying cash generation is strong enough to support both dividends and debt repayment.
The balance sheet is currently carrying significant debt from recent acquisitions, but it remains manageable. With a debt-to-equity ratio of 0.58x, the company has enough cushion to service its obligations. Management has made it clear that reducing this debt is a top priority, which should lower interest expenses and improve net earnings over time.
L3Harris is a financially disciplined defense giant that is successfully turning a massive pile of government orders into growing cash flow.
The Space and Communications segments are seeing record demand as the military modernizes its satellite networks and tactical gear. This high demand has pushed the total order backlog to a record $32 billion, providing clear revenue visibility for years. The "LHX NeXt" efficiency program is also beginning to show results in stabilizing operating margins.
Supply chain constraints in the rocket propulsion segment could slow down the speed at which the company converts orders into cash. If L3Harris cannot get the specific components it needs for missile engines, revenue growth might lag behind the strong order numbers. Management is currently working to diversify its suppliers to prevent these bottlenecks.
The global defense and aerospace market is valued at roughly $800 billion today and is projected to exceed $1 trillion by 2028 as nations modernize their militaries. It is a structurally favorable industry because the primary customer is the government, which prioritizes performance and security over the lowest price. L3Harris stands as a "tier-one" provider, meaning it has the scale to lead major programs rather than just supplying parts to others. This position gives it a significant growth runway as defense budgets shift toward the space and cyber technologies where L3Harris is strongest.
The defense market is rationally structured but requires immense scale and security clearances to survive. Barriers to entry are extremely high because new players cannot easily replicate decades of government relationships and specialized testing facilities. While competition for new contracts is fierce, once a company wins a "program of record," it usually holds that business for decades.
L3Harris faces its toughest competition from Northrop Grumman and Lockheed Martin, who have deeper pockets and longer histories of managing massive programs. Northrop Grumman is a direct threat in rocket propulsion now that L3Harris owns Aerojet, while Lockheed Martin often wins the largest overall contract awards. The most dangerous threat is the "Big Three" defense giants using their massive scale to bundle electronics and propulsion into their own platform bids.
L3Harris is successfully holding its ground and gaining share in niche areas like tactical radios and small satellite sensors. Its "Trusted Disruptor" strategy has allowed it to win contracts that previously went to larger, slower rivals.
The primary source of protection is high switching costs. Once the U.S. military trains thousands of soldiers to use L3Harris radios and builds them into every vehicle, replacing them would cost billions and take years. The company currently sits on a $32 billion backlog, which serves as physical proof of this customer lock-in.
The current financial numbers show a business with structural advantages, though its ROIC of 5.4% is temporarily weighed down by recent acquisition costs. The combination of high gross margins (25%) and a multi-year backlog proves that L3Harris has a real competitive edge that rivals cannot easily disrupt. These are not the numbers of a commodity business but of a specialized technology provider.
The moat is stable and likely strengthening as the integration of Aerojet Rocketdyne makes L3Harris a more complete partner for the Pentagon. The key signal is the book-to-bill ratio staying above 1.0, showing the competitive edge is translating into new wins.

Capital Allocation Track Record
Christopher Kubasik has shown strong strategic judgment by transforming L3Harris from a tactical radio company into a top-tier defense prime through aggressive but calculated acquisitions. He has successfully navigated the complex regulatory approval process for the Aerojet Rocketdyne deal, which many analysts initially doubted. The management team's ability to maintain high execution during this massive integration while launching a $1 billion cost-cutting initiative shows a high level of operational caliber.
The leadership risk is low because L3Harris has a seasoned bench of presidents running its major segments, though Kubasik's vision is the primary driver of the current strategy. The board is independent and has aligned executive pay with long-term goals like free cash flow and margin expansion rather than short-term stock moves. While the company is highly dependent on its relationships with the Pentagon, the management team consists of industry veterans who have spent decades navigating that specific environment.
We expect revenue to grow from $22.0B in FY2026 to $31.6B in FY2031 (~8% CAGR), with EPS growing from $10.65 to $19.10 (~12% CAGR). Revenue growth is sustained by the steady ramp-up of long-term defense contracts and increasing global demand for modernized tactical communications. Operating margins expand as the company integrates its Aerojet Rocketdyne acquisition and achieves greater manufacturing Operating margin expected to reach ~14% by FY2031.
Dominance in missile defense propulsion via the Aerojet acquisition. If L3Harris scales its rocket motor production, it becomes the indispensable provider for the Pentagon's top priority: missile defense.
Tactical radio refresh for international allies and NATO. Rising global tensions are driving a massive replacement cycle for secure communications gear that L3Harris leads.
Large-scale satellite constellation contracts for the Space Force. The shift toward hundreds of small satellites instead of a few large ones plays directly to L3Harris's strengths in sensors.
Supply chain bottlenecks in critical rocket motor components. If the company cannot source specific chemicals or parts for engines, its $32 billion backlog won't turn into cash.
Shifts in U.S. defense budget toward cyber over hardware. A sudden pivot in government spending away from physical platforms would damage the propulsion and mission systems segments.
Integration delays or hidden liabilities within recent acquisitions. Failing to hit the $1 billion savings target from LHX NeXt would leave the company with too much debt.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach, applying a multiple to the next fiscal year's earnings. This fits L3Harris because the company has highly predictable cash flows backed by government contracts and a massive backlog, making earnings the most reliable signal of long-term value.
Our fair value of $325 is derived from the FY2027 EPS estimate of $11.62 multiplied by a 28x forward multiple. This 28x multiple sits above the peer range of 18x to 21x (Lockheed Martin at 18.5x and Northrop Grumman at 21x) because L3Harris is growing organically at nearly triple the rate of the larger defense primes. We use the FY2027 EPS of $11.62 provided in the deterministic engine projections to reflect the full impact of the Aerojet Rocketdyne integration.
A cross-check using EV/EBITDA produces a fair value of $271, which is within 16% of our primary P/E target and confirms a positive valuation trend. We used a projected FY2026 EBITDA of $3.5 billion and applied a 17.5x multiple, which is consistent with the company's historical average of 17.4x. While slightly more conservative than the P/E method, it accounts for the heavy capital expenditures required for the new sensor manufacturing facilities in Rochester and Huntsville.
We're assuming L3Harris can convert its record $40.7 billion backlog into revenue at an organic growth rate of 10% or higher through 2027. This is supported by the Q1 2026 results showing 15% organic growth and a book-to-bill ratio of 1.4x, which indicates demand is significantly outstripping current production.
We're assuming the "LHX NeXt" transformation plan successfully expands segment operating margins toward the low-16% range by FY2026. Management has already realized a 120-basis-point expansion in GAAP operating margins this quarter, suggesting that workforce optimization and IT system streamlining are yielding tangible results.
We're assuming the Aerojet Rocketdyne segment maintains its 12% organic growth trajectory as a primary supplier for missile propulsion. With recent retaliatory strikes in the Middle East and ongoing support for Ukraine, demand for munitions and the propulsion systems that power them remains at a multi-decade high.
The biggest risk is a shift in U.S. defense budget priorities that favors legacy "big iron" platforms over L3Harris's agile, technology-focused systems. This shift would cause the forward multiple to compress from 28x to 21x, knocking roughly $81 off the per-share fair value. Watch the Department of Defense "Unfunded Priorities List" for any signs of procurement delays in resilient communications or tactical radios.
Bear case ($260): Book-to-bill ratio (new orders vs. current revenue) drops below 1.0x for two consecutive quarters; or Space segment operating margins contract below 10% due to persistent project underutilization.
Bull case ($380): Aerojet Rocketdyne organic sales growth exceeds 15% as global missile demand accelerates; or LHX NeXt cost-savings program delivers $1B in cumulative savings ahead of the 2026 schedule.

The market is leaning bullish because L3Harris is successfully transforming into a primary defense contractor capable of managing large-scale national security projects. By integrating the Aerojet Rocketdyne acquisition, the company now controls essential solid rocket motor production. This vertical integration allows them to capture higher margins on complex systems like the VC-25B aircraft.
Skeptics think that spinning off the missile solutions business reveals underlying cracks in the company's ambitious integration strategy. Selling off this division through a separate public offering suggests that the company is struggling to manage its diverse portfolio and is choosing to offload units to stabilize its remaining core business.
