Lockheed Martin (LMT)

Lockheed Martin is the largest defense contractor in the world: a moat of security clearance barriers + decades-long program incumbency (F-35, Trident II, Aegis) + extremely high switching costs for the government customer, with ROIC ~32% (with book equity kept very low by years of buybacks) and a record backlog of $193.6bn (+11%). The F-35 is the anchor program (27% of consolidated revenue). The first-order risk is the recognition of one-off losses on fixed-price contracts, already materialized in FY2024-25.

A defense contractor is valued on EV/EBIT over operating income (stock-based compensation is low, ~0.4% of revenue, with no SBC trap). At ~$558, that is ~16× — below the floor of the aerospace band (15-22x) and the cheapest multiple among the large contractors in the group, which generally trade richer on earnings. The market penalizes operating margin hit by the FY2024-25 reach-forward losses, without distinguishing the one-off catch-up from the business's value-generating capacity.

The base scenario projects operating income growing ~6.4%/year (backlog converting at a good pace + margin recovering toward, without exceeding, the ~12.6% historical level of FY22-23) from ~$9.2bn to ~$12.5bn in five years, at an exit multiple of 16x — in the low end of the aerospace band (15-22x, at the level of General Dynamics), a modest reversion from the ~14.8x of today that recognizes fixed-price contract risk without crediting a full re-rating. With the buyback (decelerating from $7.9bn in FY22 to $2.25bn TTM), that produces ~$879/share → a total return of +12%/year.

It trades at a real discount to value, though short of the required margin of safety. Operating income compounds ~36% over five years (~$9.2bn → ~$12.5bn) and the multiple recovers from a level currently below the floor of its own archetype toward the low end of the band (General Dynamics' level) — a partial, disciplined correction, not a full re-rating: reach-forward losses recurred in FY24 and FY25, so the base case does not assume they disappear entirely. The verdict is Undervalued. The adverse scenario (new reach-forward losses + OTA pressure + multiple compressing to the floor of the band) still leaves the value close to today's price; the favorable scenario (backlog accelerating + margin recovering above the historical level + multiple at the top of the band) is a much larger upside. This is the pattern of a quality franchise penalized by ugly recent GAAP results, not of a broken business.

Three things. First, new reach-forward losses: if they appear on other fixed-price contracts (not just the ones already recognized), the margin-recovery thesis weakens — this is the central disconfirming factor. Second, the U.S. defense budget: 72% of sales depends on annual Congressional appropriations, with risk of cuts or prolonged government shutdowns. Third, competition from non-traditional contractors favored by other transaction authority (OTA) on new programs. The gauge is simple: if operating margin keeps recovering quarter over quarter without new large charges, the re-rating toward the aerospace band is a matter of time.
