Is HII a Buy? What to Consider in 2026
Last updated June 2026
Short answer
There is no universal answer to whether HII is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for Huntington Ingalls, 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.
Huntington Ingalls Industries is the largest military shipbuilder in the United States. It designs, builds, and maintains the most complex naval vessels in the US fleet, including nuclear-powered aircraft carriers, nuclear submarines, amphibious assault ships, and surface combatants. The company operates two principal shipyards: Newport News Shipbuilding in Virginia, which is the only US builder of nuclear aircraft carriers and one of two builders of nuclear submarines, and Ingalls Shipbuilding in Mississippi, which builds amphibious and surface ships. A third segment, Mission Technologies, provides defense and federal technology services including unmanned systems, cyber, and intelligence support. HII makes money almost entirely from the US Navy and government through long-cycle contracts that span years or decades, giving it deep visibility into future revenue via a large backlog. Spun off from Northrop Grumman in 2011 and headquartered in Newport News, Virginia, HII occupies a near-monopoly position in critical naval shipbuilding.
The case for Huntington Ingalls
1. Irreplaceable shipyards.
Newport News is the only US shipyard capable of building nuclear-powered aircraft carriers and is one of just two that build nuclear submarines. These capabilities require decades of accumulated expertise, specialized facilities, and a skilled workforce that cannot be quickly replicated. This effective monopoly on the most strategic naval assets gives HII enduring relevance to national defense and pricing leverage.
2. Long backlog and submarine demand.
HII carries a backlog measured in tens of billions of dollars, providing years of revenue visibility. US Navy plans to expand the submarine fleet, including Virginia-class and Columbia-class programs, plus carrier construction, underpin a long runway of work. Naval shipbuilding is a national priority amid great-power competition, supporting sustained government investment.
3. Mission Technologies growth.
The Mission Technologies segment provides higher-growth, less capital-intensive defense services including unmanned underwater and surface vehicles, cyber, electronic warfare, and intelligence support. This diversifies HII beyond steel-bending shipbuilding toward technology-driven defense work, which can carry better margins and aligns with where modern defense spending is shifting.
The risks to weigh
HII depends almost entirely on the US government, so budget delays, continuing resolutions, or shifts in defense priorities directly affect it. Shipbuilding is enormously complex, and the company has faced cost overruns, schedule slips, and inflation in labor and materials that can pressure margins on fixed-price work. Skilled-labor shortages and supply chain constraints in the defense industrial base are persistent challenges. The business is capital intensive with long cash conversion cycles. Concentration in a few massive programs means problems on any one ship can be financially significant, and free cash flow has at times been volatile.
Valuation context (as of early 2026)
- Revenue (TTM): ~$12 billion
- Operating margin: ~7%
- Net income (TTM): ~$550 million
- P/E (TTM): ~17x
- Backlog: ~$50 billion, multi-year visibility
- Dividend yield: ~2%
- Free cash flow: variable, sensitive to program timing
HII trades at a moderate valuation relative to broad defense peers, reflecting thinner shipbuilding margins, capital intensity, and a history of program cost pressure, balanced against an essentially irreplaceable strategic position and a large multi-year backlog. The market tends to value the durability and backlog visibility while discounting for execution and margin risk inherent in complex naval construction.
How to decide for yourself
Rather than asking whether HII 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 HII indirectly through an index or sector ETF before adding more.
