KBR vs LDOS: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: KBR is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. KBR and LDOS share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined KBR and LDOS exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

KBR, Inc. is a Houston-based company that provides engineering, technical, and professional services to government and commercial clients. It operates through two core segments: Government Solutions, which supports US and allied defense, intelligence, space, logistics, and mission programs, and Sustainable Technology Solutions, which licenses proprietary industrial process technologies tied to refining, chemicals, ammonia, and emissions reduction. The government business is by far the larger of the two, accounting for roughly 72 percent of overall sales, while the technology unit carries higher margins and licensing economics.

Leidos Holdings is a large government services and technology contractor that builds and runs mission systems for U.S. federal agencies and allied governments. Its work spans intelligence and digital modernization, cybersecurity, defense systems, homeland security (including airport and border screening technology), and health services such as medical exams and health IT. Roughly the bulk of its revenue comes from the U.S. government, making it a prime contractor on long-duration programs rather than a commercial-product company.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• KBR drivers: Defense and mission-support demand; Planned spinoff of the government unit.
• LDOS drivers: Large backlog and revenue visibility; Margin expansion and cash generation.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: KBR depends heavily on US government budgets, appropriations timing, and contract awards, so shifts in defense or agency spending can pressure revenue. For LDOS, the overwhelming majority of Leidos revenue comes from the U.S.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick KBR if you believe its drivers more; LDOS if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the KBR and LDOS guides.

KBR. As of July 2026, KBR trades at a low-double-digit earnings multiple, a discount to many government-services and engineering peers. Trailing revenue is roughly $7.8 billion with adjusted EBITDA margins near 13 percent. A large backlog supports multi-year visibility, though the pending government-business spinoff makes standalone valuation harder to pin down.

LDOS. In its most recent quarter (fiscal Q1 2026, ended early April 2026), Leidos posted about $4.4 billion in revenue, non-GAAP EPS of roughly $3.13, and adjusted EBITDA margin near 14%, and it raised full-year guidance. The stock trades at a low double-digit trailing P/E, a discount to the broader market that reflects its slow-growth, government-dependent profile. Figures are approximate and change with new filings and price moves.

Headline figures (approximate, JULY 2026): KBR shows revenue (ttm) ~$7.8B, market cap ~$4.5B, p/e (ttm) ~12x, adjusted eps (ttm) ~$3.20; LDOS shows revenue (ttm) ~$17.5B, fy2026 revenue guidance ~$18.0B to $18.4B, latest quarter revenue ~$4.4B (up ~4% YoY), total backlog ~$48B.

KBR and LDOS are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
