Is LHX a Buy? What to Consider in 2026

Last updated June 2026

Short answer

There is no universal answer to whether LHX is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for L3Harris Technologies, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.

L3Harris Technologies is a major US defense and aerospace contractor formed by the 2019 merger of L3 Technologies and Harris Corporation. It positions itself as an agile defense-technology company spanning communications, sensors, electronic warfare, space, intelligence, and missile systems. The business is organized into segments covering Space and Airborne Systems (avionics, sensors, electronic warfare, space payloads), Integrated Mission Systems (ISR, maritime, electro-optical), Communication Systems (tactical radios, secure communications), and, following its acquisition of Aerojet Rocketdyne, a propulsion segment that makes rocket motors and missile propulsion for the US military and space programs. L3Harris primarily sells to the US Department of Defense, allied governments, and intelligence agencies under long-term contracts, which gives it durable, often multi-year revenue backed by defense budgets. It makes money by designing, building, and supporting mission-critical hardware and software, then earning long-tail revenue from sustainment, upgrades, and spare parts. The company also pursues cost-savings programs to expand margins after its large merger and acquisitions. Headquartered in Melbourne, Florida.

The case for L3Harris Technologies

1. Rising global defense spending.

Heightened geopolitical tensions, the war in Ukraine, and renewed great-power competition are driving sustained increases in US and allied defense budgets. L3Harris's exposure to communications, electronic warfare, missiles, and space positions it in priority spending categories, supporting a long runway of demand for its mission-critical systems.

2. Diversified mission-critical portfolio.

L3Harris spans tactical radios, sensors, electronic warfare, ISR, space payloads, and, via Aerojet Rocketdyne, missile and rocket propulsion. This breadth reduces reliance on any single program and aligns the company with multiple modernization priorities, from secure communications to space and munitions, all backed by long-term government contracts.

3. Aerojet Rocketdyne and propulsion.

The Aerojet Rocketdyne acquisition added solid rocket motor and missile propulsion capabilities at a time when the US is racing to replenish and expand its munitions stockpiles. As a key domestic propulsion supplier, this segment taps strong, structurally growing demand for tactical and strategic missiles and space launch.

4. Margin expansion and capital returns.

After its large merger and acquisitions, L3Harris is executing cost-savings programs to lift margins and integrate operations. It returns substantial cash to shareholders through a growing dividend and buybacks, supported by predictable, backlog-driven cash flow from long-term defense contracts.

The risks to weigh

L3Harris depends heavily on US government and allied defense budgets, so spending cuts, continuing resolutions, government shutdowns, or shifting priorities directly threaten revenue. Large fixed-price development programs can run over budget and hurt margins. Integrating major acquisitions like Aerojet Rocketdyne carries execution risk, and the balance sheet carries meaningful debt from deal-making. Program delays, cost overruns, supply-chain constraints, and procurement protests are recurring risks. Defense stocks can also de-rate on hopes for reduced geopolitical tension or political pressure on the defense budget, and the business is exposed to contract-concentration and regulatory risk.

Valuation context (as of early 2026)

Revenue (TTM): ~$21 billion
Operating margin: ~15%
Net income (TTM): ~$1.5-2 billion
P/E (TTM): ~20x
Dividend yield: ~2%
Backlog: tens of billions in contracted future revenue
Free cash flow: ~$2 billion+ annually

L3Harris trades at a defense-sector multiple supported by a large multi-year backlog, predictable government revenue, and steady free cash flow. The valuation reflects the durability of defense spending and the company's margin-expansion and capital-return story, offset by debt from acquisitions and program-execution risk. Defense names like L3Harris are often valued on backlog visibility and free cash flow as much as headline earnings.

How to decide for yourself

Rather than asking whether LHX is a buy in the abstract, it tends to help to answer four questions:

Thesis: do you believe the case above, and is it still true today?
Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
Overlap: check whether you already hold LHX indirectly through an index or sector ETF before adding more.
