Leidos Holdings Inc (LDOS)

Investment Committee Summary

Investment Thesis

At $138 on 25 August 2026, Leidos changes hands at roughly 11 times forward earnings and a low multiple of enterprise value to revenue — a discount that prices defence-budget stagnation and no margin progression. That is the market's implied view: a low-margin services book with limited pricing power and a continuing-resolution overhang. The engine builds its own view rather than borrowing the tape's. The base path converts a large backlog at modest growth on an operating margin near 10%, and the capital-spending-to-depreciation bridge matters because trailing capital spending sits below the forward glidepath the plan implies. The read is driven by the weighted triangulation rather than the peer screen: comparable industrial-services multiples are structurally richer and are discounted rather than applied. Triangulated fair value of $105 is a gap of -24% to the quote, the probability-weighted expected value is $120 and the twelve-month target is $124; the shares are trading rich to the weighted anchors, which is what produces the SELL. The single most damaging risk is appropriations: a sequestration-style cut re-baselines firm-fixed-price programmes at a loss, compressing earnings and the multiple together.

Narrative drafted 2026-08-16 by claude-opus-5 under supervision; reviewed by Marinus 2026-08-16.

The dashboard below is the whole argument on one page: spot ($138) against each valuation anchor, the scenario tree, technicals and the options-implied move.

Anti-Thesis (The Real Bear Case)

The highest-probability bear mechanism is the structural defence-budget cut, and it carries the largest weight of any downside state. US defence discretionary spending is not guaranteed to grow: a debt-ceiling deal or a sequestration-style cap could freeze appropriations, while a prolonged continuing resolution starves new-start task orders and recompetes intensify. Leidos earns a thin operating margin near 10% on firm-fixed-price work, so a re-baselined programme or a lost recompete flows almost undiluted into earnings. Carrying net debt of ~$6.5B, enlarged by recent acquisition outflow, a softer cash-flow path lifts leverage and curbs the buyback that has supported per-share earnings. In that state revenue contracts, the margin compresses below the base assumption, and the services multiple de-rates toward trough. Earnings and the multiple fall together, and the structural target sits below the 52-week low.

Key Debate

Gross Margin explains 64% of Monte Carlo outcome variance — the single variable that decides which side is right.

What the Market Is Pricing In

At the current price, the market pays 11.2× consensus forward EPS, vs the house DCF terminal 8.0×, and a peer median 17.5×. The house DCF sits 34% below spot, so the market is pricing in more than the house case — roughly 2.6pp of revenue CAGR.

Variant perception: the house view is below-consensus, and the thesis is primarily event-driven.

Scenario Analysis

The scenario tree spans a structural 'Structural — Defense-Budget Cuts / Aero-Production Halt' downside ($54.60) to a 'Bull — Re-Rate' bull case ($213); the probability-weighted blend (PWEV $120) is -13% versus spot.

Share-count charge: none applied. The probability-weighted value above is the gross per-share figure — no annual dilution is deducted — stock-based compensation runs at 0.5% of revenue; free cash flow net of SBC is $1.53B. SBC is therefore disclosed, not charged: read the per-share figures as before dilution.

Scenario rationale — the driver path behind every target:

• Structural — Defense-Budget Cuts / Aero-Production Halt (20%, $54.60). Structural impairment — defense-budget cuts / aero-production halt: earnings AND the multiple compress together. Target sits below the 52-week low by construction.
• Cyclical Downturn — Air-Traffic / Program Recession (17%, $88.60). Cyclical downturn — defense budgets + commercial-aero OE/aftermarket cycle + program execution weakens for 1–2 years before normalising.
• Base — Backlog + Aftermarket (35%, $125). Mid-cycle — normalised defense budgets + commercial-aero OE/aftermarket cycle + program execution; disciplined capital allocation; steady returns.
• Growth — Rearmament / Air-Traffic Recovery (20%, $166). Upside — rearmament + air-traffic recovery lifts earnings above mid-cycle; the multiple expands modestly.
• Bull — Re-Rate (8%, $213). Upside tail — sustained tight conditions or a structural re-rate on rearmament + air-traffic recovery.

Valuation Triangulation

Three weighted anchors — an intrinsic dcf, a scenario-weighted pwev and a monte carlo median (student-t + regime switching) — read them with their basis in mind. The Monte Carlo, the DCF terminal and any peer re-rate key off a market multiple, so they are not fully independent; only discounted cash flows themselves are genuinely multiple-free. The discipline is to read the spread and weight the cash-based view, not to treat three numbers as three independent votes.

The house blend DECLARES five anchor weights — DCF 35%, scenario PWEV 25%, Monte Carlo 15%, sum-of-parts 15%, peer re-rate 10%. For this name sum-of-parts, peer P/E re-rate are not computed, so 25% of the declared weight is redistributed across the anchors that exist — which is why the weights above differ from the declared ones. The fair value is unaffected by this disclosure; the blend has always worked this way.

Peer EV/Revenue re-rate — 0% weight: it duplicates the peer-multiple information already carried by the Peer P/E anchor while ignoring margin mix; weighting both would double-count the peer view. Shown as a cross-check.

Monte Carlo — the outcome distribution

10,000 paths, Student-t shocks (fat tails) with a regime-switching overlay. The median lands at $109 and 34% of paths finish above spot. The variance decomposition shows the gross margin is the dominant swing factor (64% of variance). The fundamental driver, not the multiple, sets the spread — a cleaner setup.

DCF — the cash-flow anchor

Independent of the market multiple: a 5-year path, WACC 8.5%, 8.0x terminal FCF multiple → $92.12. This anchor is deliberately the heaviest (47%): it is the valuation least hostage to the current multiple regime.

Peer benchmarking — relative value

Against the peer cohort, re-rating to the peer-median EV/Revenue multiple implies $534; the peer-median forward P/E is 17.5x, but the engine carries no P/E-implied price for this name (no forward-EPS basis at the peer step). A premium is only justified by superior growth/margins; otherwise it is multiple risk. Excluded from the weighted blend — shown only as a market cross-check.

Across all anchors the spread is 368% of the median — wide (genuine disagreement — the blend carries low valuation confidence).

Sensitivity

DCF/share — WACC × terminal multiple

DCF/share — revenue CAGR Δ × op-margin Δ

Tornado — DCF/share swing by driver (widest first)

Company lever — SoP/share vs Aerospace & Defense multiple (AI re-rating) (base 10.0x)

Peer Quality & Weighting

Quality-weighted forward P/E: 18.6× (simple median 17.5×). Direct peers count 100%, segment 50%, broad 25%.

Historical-range cross-check: 52-week range $99.65–$204, centre $143 (+3% vs spot); spot sits at the 37th percentile of the range. Low-weight mean-reversion cross-check, not a fundamental anchor.

Risk / Reward & Margin of Safety

That ratio compares triangulated upside against the probability-weighted bear target, not the extreme tail; with a leg missing it is withheld rather than computed from a magnitude. Bull case (Bull — Re-Rate): $213.

Company Overview & Business Model

Leidos Holdings Inc — TECHNOLOGY · INFORMATION TECHNOLOGY SERVICES. Leidos, formerly known as Science Applications International Corporation (SAIC), is an American defense, aviation, information technology (Lockheed Martin IS&GS), and biomedical research company headquartered in Reston, Virginia, that provides scientific, engineering, systems integration, and technical services.

How it makes money.

Edge. Narrow moat — Leidos's moat is narrow — incumbency on long-tenor US government/defense IT and services contracts, security clearances and past-performance qualification create switching costs and high recompete win rates, but it is a low-margin cost-plus/services book with limited pricing power; a narrow moat supports roughly the ~8x forward multiple it trades at, and only a durable shift toward higher-margin digital/health and proprietary IP would justify a re-rate toward the mid-teens — absent that, budget stagnation warrants no premium to the low-double-digits.

Scenario Macro & Key Risks

Decision Rules (Machine-Checked)

Stance: Hold — 0 bullish / 0 bearish / 0 caution rules triggered of 6 evaluable (0 lacked data).

Machine-checked rules over disclosed inputs. The authored falsification triggers elsewhere in this report are analyst judgment and are NOT evaluated here. The stance is a portfolio-management signal and does not modify the published research rating.

Reasons the Thesis Could Fail (Falsifiable)

Pre-registered signals that would break the thesis — each polices a specific scenario boundary and is checked at every earnings update:

• Book-to-bill (trailing twelve months) < 1.0 (2 consecutive prints). Sub-1.0 TTM book-to-bill for two quarters signals backlog erosion and undercuts the mid-single-digit organic growth the base case converts.
• Organic revenue growth (year-on-year) < 0.015 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Non-GAAP operating margin < 0.099 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Net debt / EBITDA > 3.5 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Free cash flow conversion (FCF / adjusted net income) < 0.9 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)

Fact / Inference / Speculation

• FACT: Spot $138; 52-week range $99.65–$204; engine rating SELL; house target $124 (-10%). (source: Alpha Vantage 2026-08-24, 25 August 2026)
• INFERENCE: Triangulated FV $105 (-24% vs spot · triangulated FV); the rating tracks the Monte-Carlo + scenario-PWEV core; the cash-flow anchor sits below the multiple-discipline core.
• SPECULATION: At current prices the embedded bet is that Gross Margin keeps surprising favourably — an operating call the next two prints will test.

Conviction Score

Research Conviction measures the strength and quality of the research setup — input coverage, financial quality, valuation support, process agreement. It is NOT the probability that the recommendation succeeds; the forecast track record section is the evidence on that.

57.7/100 (confidence band 44.7–70.7), 49th percentile of 858 covered names (as of 2026-08-24). Weighted composite under config ros-1.19.0 — every component and its inputs below.

Missing inputs (macro tailwinds) are excluded and the remaining weights renormalised; the confidence band widens accordingly.

Score history: 57.8 → 57.8 → 59.4 → 57.6 → 57.6 → 58.4 → 57.9 → 57.9.

Probability-Weighted Return Profile

Horizon: 1 year — at this horizon CAGR equals total return by definition. Expected values are the probability-weighted sums over the full scenario set below.

The gross expected return is the probability-weighted scenario return (it reconciles to the gross PWEV); the diluted figure applies the SBC share-count charge and matches the published PWEV-based target.

Expected Alpha

Expected return minus the return this name is REQUIRED to deliver for its risk (1-year horizon). Constants are pre-registered (preregistered-static (amendment #2, 2026-07-29); not fitted to MCH outcomes).

A negative expected alpha does not change the rating — it says the expected return does not clear the risk-adjusted hurdle at today's price. Rating mechanics are unchanged by this section.

Probability Cross-Checks

Not authoritative. The scenario probabilities in this report are AUTHORED — a judgement about how the world might go, not a measurement. Nothing below modifies them, the target, the rating or any position size. These checks ask only whether anything outside our own model agrees with us; where it does not, that is information for the reader, not a correction we have quietly applied.

Authored set: 5 scenarios, probabilities summing to 1.0, mean target $119.98.

Cross-sectional percentiles over 858 covered names (style scores sector-demeaned; thematic = return-beta to the theme's proxy ETF). 50 = estate median.

Market interaction: correlation vs SPY +0.25, vs QQQ +0.17 (trailing ~1y daily returns).

Options Intelligence

Preferred structure: Put Debit Spread. The selector reads the equity view (direction) and the volatility surface — nothing here re-prices the chain.

• bearish with cheap options — buy defined-risk downside
• Direction bearish from the overlay conviction/rating (read-only input).
• IV/RV at the 20th percentile of the cross-section → low vol bucket. This is the measure that selects the structure above: it ranks how rich this name's implied vol is against its own realised vol, relative to other names.
• Reported alongside and not used to select: this name's own ATM IV sits at the 54th percentile of its own month-end history (decile 6). The two measures disagree here — vol is high for this name by its own history while its options are not unusually rich against its realised vol. Where they diverge, the cross-sectional measure is the one acting.
• IV term structure is in contango (longer-dated richer, slope +4.9pp) — favour longer-dated ownership (LEAPS) or calendars that are long the cheaper front.

IV term structure (contango, slope +4.9pp): 25-DTE 32% · 88-DTE 36% · 270-DTE 37%

Economics copied verbatim from the options overlay (priced from the listed chain (EOD marks)); the selector does not re-price.

Options Overlay

A defined-risk way to express the SELL equity view. Chain as of 2026-08-24 — end-of-day marks — indicative, not executable quotes.

Market signals — ATM IV 31.7% (subdued regime) · expected move ±6.6% (2026-09-18) · put/call OI 0.48 · ATM Δ 0.48 / Θ -0.10 / ν 0.14. Direction: SHORT/HEDGE (implied return -24.3% to triangulated fair value $104.73).

Bear Put Spread (Bearish) — Long 140 P / Short 105 P · 2027-02-19 · net debit $10.83 · max profit $24.17 · breakeven $129.18 · RoR 223.0% · max loss $10.83 · priced from the listed chain (EOD marks)

Defined-risk downside expression: the debit caps the loss, with the position gaining as the stock falls toward the lower strike — a way to act on a bearish view without shorting stock. Subdued implied volatility currently lowers the premium paid. Illustrative — no outcome is implied or guaranteed.

Protective Put (if held) (Hedge) — Long 140 P · 2027-02-19 · premium $13.3 · floor 1.0% · max loss $13.30 · priced from the listed chain (EOD marks)

Insurance for an existing holding — a known premium buys a floor while leaving the upside intact. A way to hold through a binary event or volatility with defined downside.

Protective Collar (if held) (Hedge) — Long 125 P / Short 150 C · 2027-02-19 · net $3.25 · floor -10.0% · cap +8.0% · priced from the listed chain (EOD marks)

For a holder who wants to stay invested but cap risk: the sold call funds most of the protective put, fencing the position into a band — a way to ride out a de-rating without selling.

Indicative options structures — a defined-risk expression of the equity view, model-and-market illustrated from the last-close chain.

Rating Bridge

Rating = SELL because:

• Probability-weighted scenario value implies -13% vs spot
• Monte Carlo median implies -21% vs spot
• DCF fair value implies -33% vs spot — but this is terminal-value sensitive (exit-multiple $92.12 vs Gordon $190, 107% apart), so it carries less weight
• Bear case (Structural — Defense-Budget Cuts / Aero-Production Halt) downside is -61% vs spot
• Net: the valuation anchor itself sits 24.3% below spot, so there is no reward leg to weigh against the bear case and the reward-to-risk ratio is withheld rather than computed off a negative upside. The rating warrants a Sell.

Model Appendix

DCF — line items

FCF is bridged: NOPAT + D&A − Capex − ΔNWC (capex intensity 4% of revenue, weighted from the segments) — not a single conversion fudge.

WACC 8.5% · Σ PV(FCF) $7B + PV(terminal) $11B = EV $18B; − net debt $6.5B → equity $12B ÷ diluted shares $0.12B = $92.12/share (exit-multiple terminal).

• Gordon terminal at 2.5% → $190/share — a genuinely non-multiple, cash-based cross-check; the exit-multiple and Gordon values bracket the terminal-value risk.
• Incremental ROIC on the forecast capex ≈ 51% vs WACC 8.5% → above WACC — the build is value-creative.

Peer set

Implied prices at the peer medians: EV/Rev → $534 (no P/E-implied price — no forward-EPS basis at the peer step).
