Lockheed Martin (LMT) concentration risks

The company's concentration profile is anchored by a dominant single-customer relationship and compounded by a high-share program dependency. The U.S. Government accounted for 72% of total consolidated sales in 2025, including 63% from the Department of War, a high-share exposure with a mixed character — the relationship is structurally embedded through long-cycle defense programs and formal contracting processes, but retains a dependency dimension because contracts can be modified, reduced, or terminated at the government's convenience. Nested within that customer concentration is a single program that amplifies the dependency. The F-35 program represented 27% of total consolidated sales in 2025 — a moderate share by disclosed size but a meaningful concentration within the government customer relationship itself. Because the F-35 program accounts for more than a quarter of all revenues, shifts in annual lot pricing negotiations, foreign military sales, or program-level scope changes carry an outsized impact on results. The mixed character of this program reflects both structural (long-cycle, multi-decade support contract runway) and dependency (each production lot requires re-negotiation) elements. Together these exposures mean the investment thesis is tightly tied to U.S. defense budget dynamics, the trajectory of the F-35 program specifically, and allied government procurement decisions. Diversification across other platforms and segments exists, but the concentration at the customer and program level is the dominant variable shaping near-term revenue and margin outcomes.
