Investment Committee Summary

Investment Thesis

At $152 on 25 August 2026, near 18x forward earnings, the market prices Jacobs for steady backlog conversion at mid-single-digit growth on a thin services margin near 8.9%, with real credit already given for the data-centre and grid build-out. The engine is more cautious on all three counts. Triangulated fair value is $113, -26% against spot, leaving the shares trading rich to the blended evidence; the probability-weighted value is $125 and the 12-month target $127, and the rating is SELL. The independent discounted cash flow is the most cautious anchor of the set because incremental returns on invested capital in this business do not clear its cost of capital, so growth converts to value slowly and the market multiple, not intrinsic cash generation, is carrying the valuation. The scenario tree is skewed: the recession and structural-reset states together outweigh the growth and bull states, and the structural backlog-and-funding reset targets a price below the 52-week low. The single most damaging risk is exactly that reset. With net debt of ~$3.2B on the balance sheet and a book-to-bill that can slip below parity, an earnings cut and a multiple de-rate arrive together rather than in sequence, and a services business has no asset base to fall back on.

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 ($152) 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 a construction and funding recession, and the steelman is concrete: much of Jacobs' order intake is tied to public infrastructure and data-centre programmes whose funding is discretionary and rate-sensitive. If financing conditions tighten or public budgets are deferred, book-to-bill falls below parity, backlog stops converting, and fixed-cost under-absorption pulls an already thin margin near 8.9% lower still, because in a professional-services business utilisation is the margin. On flat-to-negative organic growth and a de-rated multiple the shares compress toward the recession path and, in a genuine reset, toward the structural path below the 52-week low. A rating near 18x forward earnings leaves no cushion for that sequence, and the gap between management's tone and outside estimates is a live warning that the optimism may be premature.

Key Debate

Gross Margin explains 62% 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 20.9× consensus forward EPS, vs the house DCF terminal 13.0×, and a peer median 45.9×. The house DCF sits 31% below spot, so the market is pricing in more than the house case — roughly 2.8pp of revenue CAGR.

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

Scenario Analysis

The scenario tree spans a structural 'Structural — Backlog / Funding Reset' downside ($56.90) to a 'Bull — Re-Rate' bull case ($222); the probability-weighted blend (PWEV $125) is -18% 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 $0.55B. SBC is therefore disclosed, not charged: read the per-share figures as before dilution.

Scenario rationale — the driver path behind every target:

• Structural — Backlog / Funding Reset (20%, $56.90). Structural impairment — backlog / funding reset: earnings AND the multiple compress together. Target sits below the 52-week low by construction.
• Construction Recession (17%, $91.20). Cyclical downturn — construction & industrial activity + backlog conversion + price/margin weakens for 1–2 years before normalising.
• Base — Backlog Conversion + Margin (35%, $130). Mid-cycle — normalised construction & industrial activity + backlog conversion + price/margin; disciplined capital allocation; steady returns.
• Growth — Datacenter / Grid / Infra Buildout (20%, $173). Upside — infrastructure + non-res + industrial buildout lifts earnings above mid-cycle; the multiple expands modestly.
• Bull — Re-Rate (8%, $222). Upside tail — sustained tight conditions or a structural re-rate on infrastructure + non-res + industrial buildout.

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 $111 and 31% of paths finish above spot. The variance decomposition shows the gross margin is the dominant swing factor (62% 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 9.5%, 13.0x terminal FCF multiple → $105. 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 $402; the peer-median forward P/E is 45.9x, 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 239% of the median — wide (genuine disagreement — the blend carries low valuation confidence).

Peer Quality & Weighting

Quality-weighted forward P/E: 42.3× (simple median 45.9×). Direct peers count 100%, segment 50%, broad 25%.

Historical-range cross-check: 52-week range $105–$167, centre $133 (-12% vs spot); spot sits at the 75th 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): $222.

Decision Rules (Machine-Checked)

Stance: Hold — 0 bullish / 1 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 book-to-bill for two straight quarters signals backlog is shrinking rather than converting, undercutting the base-case backlog-conversion thesis.
• Adjusted operating margin < 0.083 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Organic net revenue growth (year-on-year) < 0.04 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Net debt / EBITDA > 2.5 (single event). (rationale withheld pending re-authoring — frozen figure or verdict)
• Management-minus-Q&A transcript tone delta > 0.5 (2 consecutive prints). 2026Q2 already flagged an elevated +0.58 delta at the 85th book percentile. A persistently wide gap suggests management optimism is running ahead of the analyst floor and warrants disconfirmation.

Fact / Inference / Speculation

• FACT: Spot $152; 52-week range $105–$167; engine rating SELL; house target $127 (-16%). (source: Alpha Vantage 2026-08-24, 25 August 2026)
• INFERENCE: Triangulated FV $113 (-26% 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.

56.4/100 (confidence band 43.9–68.8), 44th 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: 56.9 → 56.9 → 57.0 → 56.7 → 56.7 → 57.1 → 56.7 → 56.7.

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 $124.58.

Factor Exposures

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 +0.48, vs QQQ +0.37 (trailing ~1y daily returns).

Options Intelligence

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

• bearish with rich premium — finance downside protection by selling an expensive call (collar)
• Direction bearish from the overlay conviction/rating (read-only input).
• IV/RV at the 68th percentile of the cross-section → high 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 46th percentile of its own month-end history (decile 5). 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 +3.0pp) — favour longer-dated ownership (LEAPS) or calendars that are long the cheaper front.

IV term structure (contango, slope +3.0pp): 25-DTE 28% · 116-DTE 30% · 235-DTE 31%

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 27.8% (elevated regime) · expected move ±5.9% (2026-09-18) · put/call OI 0.32 · ATM Δ 0.59 / Θ -0.09 / ν 0.15. Direction: SHORT/HEDGE (implied return -25.6% to triangulated fair value $112.77).

Bear Put Spread (Bearish) — Long 150 P / Short 115 P · 2027-01-15 · net debit $8.02 · max profit $26.98 · breakeven $141.97 · RoR 336.0% · max loss $8.02 · 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. Illustrative — no outcome is implied or guaranteed.

Protective Put (if held) (Hedge) — Long 150 P · 2027-01-15 · premium $9.7 · floor -1.0% · max loss $9.70 · 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 135 P / Short 165 C · 2027-01-15 · net $1.95 · floor -11.0% · cap +9.0% · 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. Elevated implied volatility currently enriches the premium collected.

Rating Bridge

Rating = SELL because:

• Probability-weighted scenario value implies -18% vs spot
• Monte Carlo median implies -27% vs spot
• DCF fair value implies -31% vs spot
• Bear case (Structural — Backlog / Funding Reset) downside is -62% vs spot
• Net: the valuation anchor itself sits 25.6% 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 6% of revenue, weighted from the segments) — not a single conversion fudge.

WACC 9.5% · Σ PV(FCF) $4B + PV(terminal) $11B = EV $15B; − net debt $3.2B → equity $12B ÷ diluted shares $0.12B = $105/share (exit-multiple terminal).

• Gordon terminal at 2.5% → $117/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 ≈ 57% vs WACC 9.5% → above WACC — the build is value-creative.

Peer set

Implied prices at the peer medians: EV/Rev → $402 (no P/E-implied price — no forward-EPS basis at the peer step).
