Diamondback Energy (FANG) — Stock Analysis 2026 [4.2]

Analysis as of 7 September 2026. This is a point-in-time snapshot, not an evergreen guide. Fundamentals are from Diamondback’s fiscal-2025 Annual Report (10-K, year ended 31 December 2025) and its Q2 2026 results (3 August 2026); market data (share price, market cap, multiples, analyst targets) is as of the 4 September 2026 close and will move. Rating: ★★★★, Solid — Overvalued (wide band) → a great company at a rich price: watch for a better entry. Price deck used in the valuation: base WTI US$70/bbl — the twelve-month trailing average of US$75.87 leaned to the lower price of the fixed US$60–100 grid, because the window carries the March–May 2026 Hormuz spike — with every grid price run as a scenario (bear US$60 / base US$70 / bull US$80 / deep bull US$90 / extreme bull US$100); Henry Hub US$3.00/MMBtu; 10% discount rate; no spot deck is carried. Refreshed on each annual report and on material events. For information only, prepared with AI assistance — see the disclaimer at the end.

Diamondback spent two years turning itself into the Permian’s last great consolidator. With the ~US$26 billion Endeavor Energy Resources merger in September 2024 and the ~US$4 billion Double Eagle bolt-on in April 2025, it became the largest pure-play Permian Basin independent — roughly 0.97 million barrels of oil equivalent per day, ~1.1 million net acres, the lowest cash cost in its peer group, and a mineral-and-royalty arm, Viper Energy, that is now the biggest listed minerals player in the basin. The thesis in one line: a best-in-class, low-cost operator sitting on 15-plus years of tier-1 inventory, throwing off a double-digit free-cash-flow yield and handing back at least half of it — priced today for oil near US$99 a barrel held flat forever. To screen Diamondback against every US upstream name on production, cost, reserve life and free-cash-flow yield, go to Metal Pilot.

1. Snapshot & thesis

Diamondback Energy, Inc. (Nasdaq: FANG) is an independent oil & natural gas exploration and production (E&P) company headquartered in Midland, Texas, operating exclusively in the Permian Basin of West Texas — split between the Midland Basin (its core after Endeavor and Double Eagle) and the Delaware Basin. It is a producer/operator by archetype and an energy producer by sector. The company controls roughly 1.10 million gross acres (~97% operated), holds about 8,854 economic horizontal drilling locations across the two sub-basins, and in FY2025 produced 0.92 million barrels of oil equivalent per day (mmboe/d) — 54% crude oil — from 6,677 producing horizontal wells. It also consolidates Viper Energy (Nasdaq: VNOM), a mineral-and-royalty subsidiary that owns the ground beneath much of the basin. (boe = barrel of oil equivalent, gas converted to oil at 6:1 by energy content; following the standard oil-field convention, mmboe = million boe and mboe = thousand boe.)

Thesis in brief. Bull: you are buying the lowest-cost operator of the best remaining rock in North American shale, with a corporate breakeven near US$37/bbl WTI, 15-plus years of inventory, a ~10–12% free-cash-flow yield and a policy of returning at least half of it — the compounding machine of US onshore. Bear: it is a price-taker on a single commodity in a single basin, still carries ~US$12 billion of net debt from its acquisition spree, and printed a GAAP net loss in Q4 2025 when oil and Waha gas cratered. What tips it: whether the conflict-era oil price the shares now capitalise persists — versus a reversion toward the mid-cycle deck the trailing average and the EIA’s 2027 forecast both point at, which is where the valuation in Section 7 lands. The full rating and its rationale are in Section 9.

2. Assets & operations

Diamondback is a leveraged play on one commodity in one place, so the backdrop matters: after a soft 2025 (WTI averaged US$65.46/bbl), crude spiked through the Strait of Hormuz disruption to a monthly peak of US$102.13/bbl in May 2026 and averaged US$83.90 in August, well above the US$64.04 FY2025 realizations imply. For the full picture of how crude is priced, who produces it and how it behaves across cycles, see the Oil — A Complete Market Guide ; the gas and NGL side, which sets Diamondback’s Waha-exposed realizations, is covered in the Natural Gas guide . This section spends its words on the company.

2.1 Portfolio overview & map

Unlike a multi-basin major or a royalty company with hundreds of interests, Diamondback’s “portfolio” is a single contiguous Permian position, best understood as two sub-basins plus a minerals arm. The concentration is the point: ~97% operated, ~1.1 million net acres, and a drilling program that is among the most capital-efficient in the industry at roughly US$550 per lateral foot.

Table 2. Asset base at a glance, FY2025

Source: Diamondback FY2025 10-K , Items 1–2; Q4/FY2025 results . WI = working interest; D&C = drilling & completion; PUD = proved undeveloped. Sub-basin output split is approximate. All acreage is publicly listed operated interest (Nasdaq: FANG).

The whole business sits in Texas and southeastern New Mexico — the top-decile oil & gas jurisdiction on earth for rule of law and infrastructure — which is Diamondback’s single greatest structural advantage and, in the same breath, its single-basin concentration risk (Section 6).

2.2 Revenue split — by product & by asset

Two cuts of the same revenue base tell the concentration story. By product, Diamondback is far more of an “oil company” than its 54%-oil volume mix suggests, because oil sells for many times the per-barrel price of gas: crude was roughly 86% of upstream commodity revenue in FY2025, with NGLs ~11% and natural gas just ~3% — the residue of a year in which Waha gas realized only US$0.89/mcf. By asset, revenue collapses to the two sub-basins plus Viper’s royalty, with the Midland Basin the clear majority after Endeavor and Double Eagle.

Figure 2. FY2025 revenue by product

Figure data: Diamondback FY2025 results ; shares of upstream oil, NGL and gas sales derived from FY2025 realized prices (oil US$64.04/bbl, NGL US$17.88/bbl, gas US$0.89/mcf) and volumes.

Figure 3. FY2025 production by segment

Figure data: Diamondback FY2025 10-K ; sub-basin and Viper-royalty shares of ~336.2 mmboe/yr are approximate.

Read together: Diamondback’s cash flow lives and dies on the oil price (a gas-price recovery is upside, not the base case), and it is concentrated in the Midland Basin — the highest-return, lowest-cost half of the Permian. For a single-play producer there is no meaningful “by-mine” split to draw; the honest picture is a sub-basin one.

2.3 Midland Basin — the core (post-Endeavor)

The Midland Basin is the thesis. The US$26 billion Endeavor merger (September 2024) roughly doubled Diamondback’s Midland footprint and handed it a contiguous, largely-undrilled inventory of the basin’s best rock; the US$4 billion Double Eagle deal (April 2025) added ~40,000 net acres, ~9.9 mmbbl/yr and 407 more locations right in the core. Today the Midland Basin supplies roughly two-thirds of production and the bulk of the 3.62-billion-boe proved reserve base, at a drilling-and-completion cost (~US$550/ft) that is among the lowest in the industry and a corporate breakeven near US$37/bbl WTI to sustain the base dividend and hold volumes flat. This is where the low-cost story is made: long laterals, dense infrastructure, and the deepest tier-1 inventory of any pure-play. The key asset-level risk is simply price — a low-cost operation on high-quality rock has few operational fragilities, so its downside is the commodity, not the geology.

2.4 Delaware Basin — the second leg

The Delaware Basin (West Texas and southeastern New Mexico) is roughly a third of output — gassier and marginally higher-cost than the Midland, but with longer laterals and a substantial proved-undeveloped book that gives Diamondback a second decade of running room. It also carries more of the company’s exposure to New Mexico regulation and to the Waha gas-basis blowouts that hammered 2025 gas realizations. It is a genuine second core, not a fringe, and it is where a chunk of the future growth and any gas-price optionality sits.

2.5 Viper Energy — the minerals arm (VNOM)

Diamondback’s cleverest structural asset is Viper Energy, a majority-owned, separately-listed mineral-and-royalty company it consolidates. Viper owns the mineral rights — the royalty — under a large slice of the Permian, so it collects a share of revenue from wells (Diamondback’s and third parties’) with no capital or operating cost, producing a near-100% cash-margin stream. In June 2025 Viper agreed to buy Sitio Royalties for ~US$4.1 billion in an all-equity deal, combining the two largest listed Permian minerals players and lifting Viper’s production to ~47.5 mmboe/yr by Q4 2025 (from ~36.5 mmboe/yr for the full year). Diamondback also “drops down” minerals into Viper (a ~US$873 million Permian drop-down in 2025), monetizing its own ground while keeping majority economic exposure. Viper is both a source of high-margin cash flow within the consolidated results and a sum-of-the-parts asset in its own right (Section 7); the trade-off is a noncontrolling interest — a meaningful share of Viper’s value belongs to public VNOM holders, and must be netted out to value Diamondback’s equity.

2.6 Other assets & the development pipeline

Beyond the two sub-basins and Viper, Diamondback runs a set of midstream and infrastructure interests (gathering, water, and equity stakes such as the EPIC crude pipeline system) and an active portfolio-management program — ~US$1.7 billion of non-core divestitures in 2025 to high-grade the base and fund deleveraging. The “pipeline” for a mature producer is its drilling inventory: ~8,854 economic horizontal locations, roughly 15-plus years at the current pace of ~500 wells a year, plus the option to consolidate further in a basin where Diamondback is now the natural aggregator. None of this is speculative blue-sky; it is contracted, low-cost running room.

2.7 Production, reserves & costs (consolidated)

At the group level, Diamondback produced 336.2 mmboe/yr in FY2025 (181.5 mmbbl/yr of oil), exiting the year at 354.1 mmboe/yr in Q4 and guiding to 365.0 mmboe/yr for 2026 (190.5 mmbbl/yr oil, the 1,000+ and 522+ mboe/d guidance raised with the Q2 2026 results). Proved reserves stood at 3,618 mmboe (49% oil) at year-end, ~70% of it proved-developed, with a 118% reserve-replacement ratio and a proved reserve life of roughly 10.8 years — extended well beyond that by the undeveloped inventory. The cost structure is the differentiator: total cash operating cost of US$10.23/boe (LOE US$5.55, production & ad-valorem taxes US$2.53, gathering/processing/transport US$1.53, cash G&A US$0.62), which underpins the industry-low breakeven. The nuance behind the headline: FY2025’s +36% revenue jump was volume-driven (the first full year of Endeavor plus Double Eagle), even as per-barrel realizations fell with a soft oil-and-gas tape — the mirror image of a price-driven year.

2.8 Peer positioning

Diamondback’s natural peer set is the large-cap US independent E&Ps, Permian-weighted: EOG Resources (EOG), Devon Energy (DVN), Coterra Energy (CTRA), Permian Resources (PR) and Matador Resources (MTDR). Every “vs. peers” claim in this analysis — each scorecard star, the cost-curve read, the valuation multiples in Section 7 — uses that set.

Where Diamondback sits: first on scale among the pure-plays and top-tier on cost, with the deepest tier-1 inventory — but with a balance sheet that carries more leverage than the best-in-class names (EOG runs near net-cash; Devon and Coterra sit below ~0.8×). That single fact is the crux of the scorecard: elite assets and cost, a merely-adequate balance sheet, all of it a price-taker on oil.

3. Financials & balance sheet

FY2025 was a record on the top line and a study in why per-share matters. Revenue rose 35.8% to US$15,026 million on the first full year of Endeavor plus Double Eagle, and operating cash flow reached US$8,758 million with free cash flow of US$5,549 million (adjusted US$5,892 million). Yet GAAP net income attributable to Diamondback fell to US$1,664 million (US$5.73 diluted) from US$3,338 million a year earlier — because the share count roughly doubled through the acquisitions and the company booked a large Q4 2025 impairment (a US$1,458 million Q4 net loss) as oil and Waha gas slumped into year-end. Strip the non-cash charge and adjusted net income was US$3,874 million (US$13.37 adjusted EPS) — the truer read of the earning power. Adjusted EBITDA was US$9,536 million, a ~64% EBITDA margin on a ~US$40/boe realized price, the signature of the low-cost model.

Table 4. Five-year financial summary

Source: Diamondback FY2025 results and FY2025 10-K , which report FY2023–FY2025 on a consistent basis; FY2021–FY2022 are from Diamondback’s prior 10-K filings, cross-checked against stockanalysis.com as a convenience mirror. FY2025 dividend is base + variable declared; the base dividend was subsequently raised to US$4.20 (Q4 2025) then US$4.40 annualized (Q1 2026). “—” = not on a consistent basis within the FY2025 filing window. EPS decline reflects share issuance for Endeavor/Double Eagle plus a Q4 2025 impairment.

The balance sheet is the watch item. Diamondback ended 2025 with US$14,563 million of net debt (~US$14.67 billion total debt against US$91 million of cash), roughly 1.5× adjusted EBITDA — elevated by the cash portions of the Endeavor and Double Eagle acquisitions. It is coming down fast: Q1 2026 net debt was US$13,894 million (~1.4× on trailing adjusted EBITDA — the Q1 basis the peer and relative-valuation tables use), and management has a stated US$10 billion net-debt target, funded by the ~US$1.7 billion of 2025 divestitures and strong free cash flow. Liquidity is ample (~US$2.6 billion available). On capital returns, Diamondback commits to returning at least 50% of quarterly adjusted free cash flow; in FY2025 it returned US$3.2 billion (54% of adjusted FCF) through a US$4.05 base-plus-variable dividend and US$2.0 billion of buybacks (13.84 million shares), and it raised the base dividend 10% year-over-year to US$4.40 annualized with Q1 2026 — a ~2.2% yield with buybacks on top.

Hedge & treasury posture. Diamondback retains most of its oil-price upside by design — FY2025 hedged oil realizations (US$63.14/bbl) sat just below unhedged (US$64.04), so oil hedging cost only pennies, while its gas hedges added real value (US$1.84/mcf realized vs US$0.89 unhedged) by protecting against Waha basis collapse. The policy is opportunistic downside protection — puts and collars on oil, basis swaps on gas — layered to defend the base dividend’s ~US$37/bbl breakeven, not a systematic program that caps the upside. There is floating-rate exposure on the revolver, partly offset as the company terms out and repays debt.

4. Management, strategy & corporate structure

4.1 Management & governance

Diamondback is now led by CEO Kaes Van’t Hof, who stepped up from President at the 2025 annual meeting and joined the board; he is the architect of the acquisition-and-integration playbook of the last decade and frames the next as “a lot like the last — an acquire-and-exploit strategy based on best-in-class execution, low-cost operations and transparency.” Founder-era CEO Travis D. Stice (chief executive since January 2012) moved to Executive Chairman through the 2026 annual meeting, preserving continuity. The finance seat is held by EVP & CFO Jere W. Thompson III (promoted February 2025 from head of strategy and corporate development), and operations by EVP & COO Daniel “Danny” Wesson, a mechanical engineer who has run Diamondback operations since 2022 after rising through completions and operations roles from 2012. The bench is deep and unusually operational for a company of this scale; the governance question a reader should weigh is execution risk through a CEO handoff at the same time the company digests its largest-ever deals. Every leadership seat here is filled by a named, credentialed executive — not a placeholder.

4.2 Strategy & capital allocation

The strategy is disciplined and consistent: be the lowest-cost operator of the best Permian rock, grow production modestly and only when it is accretive, and return the resulting free cash flow to shareholders while deleveraging. The capital-allocation stack is explicit — fund a low-breakeven maintenance-plus-modest-growth program (~US$3.9 billion of 2026 capex to hold 0.97+ mmboe/d), return ≥50% of adjusted free cash flow, and drive net debt to US$10 billion. The M&A methodology is “acquire and exploit”: buy contiguous, high-quality, undervalued acreage (Endeavor at scale, Double Eagle as a core bolt-on at ~5.2× EBITDA), wring out synergies via low-cost execution, and monetize minerals into Viper. Forward targets are concrete: 190.5 mmbbl/yr oil and 365.0 mmboe/yr total in 2026 (the 522+ and 1,000+ mboe/d guidance raised with the Q2 2026 results), drilling-and-completion costs pushed toward US$550/ft, and a multi-year march down the leverage curve.

4.3 Ownership & corporate structure

The defining structural events are three deals in eighteen months. The ~US$26 billion Endeavor Energy Resources merger (completed September 2024; ~US$26 billion including net debt, funded with roughly 117 million Diamondback shares plus about US$8 billion of cash) created the largest pure-play Permian independent. The US$4 billion Double Eagle acquisition (announced February 2025, closed April 2025; ~6.9 million shares plus US$3 billion cash) added ~40,000 core Midland net acres, ~9.9 mmbbl/yr and 407 locations at ~5.2× 2025 EBITDA. And at the subsidiary level, Viper Energy’s ~US$4.1 billion all-equity acquisition of Sitio Royalties (agreed June 2025) fused the two largest listed Permian minerals players, alongside a ~US$873 million Permian minerals drop-down from Diamondback into Viper. The noncontrolling interest in Viper — the portion held by public VNOM shareholders — is the one structural item a valuer must net out (Section 7). Diamondback funded the cash legs with a mix of balance-sheet cash, revolver and term debt, then began repaying it with divestiture proceeds and free cash flow.

5. ESG & sustainability

For an oil & gas producer, Diamondback’s environmental profile is above the E&P median and improving, though the model’s inherent Scope 3 and transition exposure caps the ceiling. On emissions, Scope 1+2 GHG intensity was 12.7 mt CO₂e per gross mboe (2024) — management describes it as peer-leading and targets holding those levels while pursuing a 50% cut from a 2020 baseline by 2030 — and methane intensity of 0.03 mt CH₄/mboe, with a 20%-by-2030 reduction goal. Flaring was 2.3% of gross gas in 2024 against a <0.2% operated target, with the company noting that ~90% of flared volumes trace to third-party midstream downtime rather than its own operations. On water, Diamondback hit 69.5% non-freshwater (recycled) use — beating its >65% goal two years early. Safety (TRIR 0.82 in 2024) is trending toward a ≤0.25 target. Named programs give the numbers substance: the Net Zero Now initiative (offsetting remaining Scope 1 emissions since 2021), a US$50 million-plus investment in Verde Clean Fuels (waste-gas-to-gasoline), the VoltaGrid electrified-frac partnership (200+ MW of micro-grid power), and the Permian Strategic Partnership (community investment across education, healthcare and workforce). The honest limitation: this is still a hydrocarbon producer whose product is burned, and flaring — though mostly midstream-caused — remains the visible gap between ambition and result.

6. Risks

Table 5. Risk register

Source: Diamondback FY2025 10-K risk factors and MD&A; this analysis. Likelihood/impact are the author’s assessment.

The through-line: Diamondback has engineered away most operational and cost risk — the geology is proven, the jurisdiction is the best available, the cost base is the lowest in the peer group — but it cannot engineer away price risk. Its biggest single vulnerability is a sustained drop in the oil price; its biggest company-specific unknown is whether it deleverages on schedule while integrating US$30 billion of acquisitions through a leadership transition; and its most idiosyncratic exposure is the single-basin bet, which is a strength in a strong tape and a concentration in a weak one.

7. Valuation

Valuation as of 7 September 2026, in US dollars. Horizon: spot fair value. Price deck: base WTI US$70/bbl — the representative trailing average snapped to the fixed US$60–100 grid (3-month US$83.06, 6-month US$90.50, 12-month US$75.87, all to end-August 2026 on the U.S. EIA Cushing monthly spot series; the twelve-month window is the representative one because the three- and six-month windows sit entirely inside the March–May 2026 Hormuz spike of US$91.38 / US$100.32 / US$102.13, and the nine months either side of it average US$68.51, so the average is leaned to the lower grid price) — with every grid price run as a scenario (bear US$60 / base US$70 / bull US$80 / deep bull US$90 / extreme bull US$100); the EIA’s August 2026 outlook, which puts Brent at US$87/bbl in 2026 and US$69/bbl in 2027 as the Hormuz disruption unwinds, is carried as a 0%-weight cross-check; no spot deck is carried, so the section does not age with the daily quote. Realized oil = WTI plus the US$0.26/Bbl Midland premium the reserve report’s own US$64.99/Bbl carries over the US$64.73/Bbl 2025 average; gas and NGLs are held at the reserve report’s US$1.32/Mcf and US$18.87/Bbl, because Diamondback’s Waha gas realisation has run below both since (Henry Hub base US$3.00/MMBtu). Discount rate 10%, the E&P convention for a single-basin, high-decline base with a sub-ten-year proved life — the rate the standardized measure is struck at — sensitised 8–12%. Share price US$199.22 (4 September 2026 close), 280.02 m shares, balance sheet as of 30 June 2026.

Diamondback is valued on the E&P producer archetype, run as a sum-of-the-parts over three claims — the proved developed reserve base, the proved undeveloped tranche the reserve report funds, and the drilling inventory beyond both. The method behind the numbers is set out in the How to Value Commodity Stocks guide; this section applies it to Diamondback. The headline is a deck-to-value map, not a single number: the blended fair value is US$129.24/share at the US$70 base price, US$86.44 at US$60 and US$171.69 at US$80, and each US$10/bbl of WTI is worth about US$31.7 of NAV/share — the deck sensitivity in Table 11 lets a reader run the model at any oil price they hold. The tiers frame the structure: the producing base plus the whole bridge is worth US$38.28/share, the proved undeveloped tranche another US$39.79, and the unbooked drilling inventory US$42.36 — an unusually even three-way split, and the reason the inventory argument is the whole argument here. The section sets the current US$199.22 price against that map only in §7.6, where the rating and the flip prices are published.

7.1 Method selection

Diamondback is a producer, so the blend is the E&P-producer default set out in the valuation guide linked above — NAV/DCF 45% / EV/EBITDA 30% / a reserve read 25% — carried without deviation. The third slice takes the guide’s reserve anchor on proved (1P) reserves, the only category an SEC filer publishes; the anchor is written for 2P, so the denominator is narrower than the convention and the method reads low, which is precisely why the drilling inventory beyond proved is priced in the NAV rather than here. Input families stay distinct — intrinsic 45%, cash-flow 30%, asset and capacity 25% — so no family approaches the collinear ceiling and no substitution is needed.

Table 6. Valuation method selection

Source: method-to-archetype mapping, anchors and the default weight set per The Commodity Investor, Part 11: How to Value Commodity Stocks , “The archetype is the unit of analysis” and “The valuation toolkit”; the E&P-producer default carried without deviation. Archetype in Section 1; target multiples derived in §7.3 from the archetype anchors, not from the Section 2.8 peer set, which stays a quality comparator. Input families: intrinsic 45% (single method), cash-flow 30%, asset & capacity 25%, transaction 0% — all inside the family caps.

7.2 Net asset value

Vehicle map. Diamondback holds its own Permian working interests directly and consolidates Viper Energy, a separately listed minerals subsidiary in which it owned about 42% on a fully diluted basis at the last report date. Viper’s reserves, revenue and debt are all inside the consolidated figures this model starts from, so the public 58% has to come back out — and it comes out at its share of Viper’s own asset value, not at the balance sheet’s carrying amount.

Table 7. Vehicle map

Source: this analysis; reserves, the Viper share of the standardized measure and the ownership percentage per the Diamondback FY2025 Form 10-K , Items 1 and 2 and Note 18; Viper’s own reserve schedule per the Viper Energy FY2025 Form 10-K ; Viper debt and cash per the Q2 2026 results, 3 August 2026.

Tax basis and asset-retirement obligations. The reserve base is carried at the SEC after-tax standardized measure, so tax is inside the figure by construction (the disclosure’s own schedule) and the balance sheet’s US$209 m of net-operating-loss and other carryforwards sit behind it — neither charged nor credited again. That schedule runs at 15.1% of pre-tax future net revenue (US$12,129 m against US$80,415 m) because the pools shelter the early years; an incremental dollar of oil price is taxed at the 23% corporate rate the company guides to for 2026, and that is the rate the deck adjustment uses. Direction: the deck sensitivity is therefore slightly conservative on the upside and slightly harsh on the downside. Future dismantlement and abandonment are already inside the reserve report’s development costs — the filing footnotes approximately US$1.1 bn of them — so the bridge’s reclamation line prints in rows and names the US$542 m balance-sheet obligation it corresponds to; the relative legs in §7.3 and §7.4 still deduct it, because neither EBITDA nor a reserve multiple carries it.

Stage risk (n/a). No asset in the model is pre-production. The proved undeveloped tranche is a booked SEC category that must be developed within five years and whose share of the US$9,425 m of future development costs is already charged inside the standardized measure, so it takes a 1.00 risk weight and neither the target P/NAV nor the discount rate carries a second charge. The one row that is risked is the unbooked drilling inventory, and its factor is derived below rather than asserted.

The per-asset NPV build. Every NPV the model carries is built here first, one block per tranche, so the arithmetic arrives before the answer. The two reserve blocks are Diamondback’s own disclosed figure apportioned on its own filed volumes and prices and moved to the deck; the inventory block is the only author construction, and it is printed as terms — locations, a filed EUR, a filed value per barrel and a derived factor — rather than as a total.

Table 8. Per-asset NPV build — base case (US$70/bbl WTI, 10%)

Notes to Table 8

1. The filing publishes the standardized measure only in total, so each of its four cost lines is apportioned on a filed quantity: revenue on the reserve volumes valued at the filing’s own SEC prices (oil US$64.99/Bbl, gas US$1.32/Mcf, NGL US$18.87/Bbl), production costs on the boe share, income tax on pre-tax net revenue. The apportionment is exact by construction: 26,992 + 9,918 = US$36,910 m, and the price set reproduces the filed US$140,499 m of future cash inflows to 0.01%.
2. The filing footnotes approximately US$1.1 bn of future asset-retirement costs inside the US$9,425 m of future development costs. That share is split on boe volumes; the remaining US$8,325 m of drilling capital is charged wholly to the undeveloped tranche, which is what it funds.
3. One discount ratio, both tranches. The disclosure gives a single US$31,376 m discount against US$68,286 m of undiscounted after-tax cash flow, and no split by category, so both tranches carry it. The developed base produces earlier and the undeveloped later, so the split understates the developed tranche and overstates the undeveloped one; the total is exact, and the same ratio implies a flat-equivalent life of 13.3 years — the annuity that reproduces 0.5405 at 10% — which is the profile the rate rows of Figure 8 move both blocks on.
4. The deck term: 1,173,636 mbbl of developed oil reserves (600,784 mbbl undeveloped) × (1 − 7.02% production taxes, the filed US$9,870 m over US$140,499 m) × (1 − 23% corporate tax) × the 0.5405 discount ratio. Gas and NGLs are held at the reserve report’s own prices across the grid: Diamondback’s realised gas was negative US$2.15/Mcf in the second quarter of 2026 on Waha constraints, and its NGL realisation fell from 29% of the oil price in the reserve report to 19% at that quarter’s oil price, so neither tracks WTI and holding both is the conservative treatment. Direction: NAV is understated if NGLs re-couple to crude.
5. The locations are the company’s own count of what is economic at approximately US$50/Bbl WTI — a filed threshold, and a low one against every price on this section’s grid.
6. The factor is derived, then capped. At 488 net wells a year (6,100–6,500 thousand feet of net lateral at ~12,900 feet, 2026 guidance) the booked queue runs 2.5 years and the unbooked queue a further 10.8, so the unbooked location is drilled about 6.6 years later than the booked average: 1.10⁻⁶·⁶ = 0.53. A tier factor of 0.67 charges the marginal rock and the 304 mmboe of downward revisions Diamondback booked in 2025. The product is 0.36; the de-risking band for resource beyond the plan tops out at 0.25, and the row takes the ceiling — so the row is conservative against its own derivation, not generous.
7. ≈ US$2.54 per unbooked boe, against US$10.16 per booked undeveloped boe in the plan.

Filed marks a figure printed in the filing, Derived the arithmetic of rows above it, Input a parameter of this section. The value column is headed Value rather than US$m because a build that multiplies heterogeneous terms cannot hold one unit; the unit sits in the line item, and only the = rows are US$m. The one relationship the table cannot express is the parametric form the sensitivity grid runs across the deck and the rate: proved(WTI, r) = [36,910 + 686.6 × (WTI + 0.26 − 64.99)] × AF(r, 13.3) ÷ AF(10%, 13.3).

Every NPV in the last column reproduces from its block in Table 8; this table adds the reserve, cost, capital, tax and discounting inputs behind those figures. One discount-rate treatment: all three carried rows re-discount on the Note 18 timing, and the grid’s notes say so.

Bridge lines in the standard order, each printed even where empty on one of the five value-column states. The tiers sum to the published NAV/share: producing US$38.28 + development US$39.79 + resource US$42.36 = US$120.43 on unrounded inputs — and the producing tier alone sits 81% below the US$199.22 price, before either undeveloped tier is counted. Values computed on unrounded inputs, printed to whole US$m and two decimals per share.

Figure data: Table 10. Equity net asset value of US$33,723 m equates to US$120.43 per share; the producing tier alone is US$38.28. “Hedge & wkg cap.” nets the hedge mark (+219) against net working capital and restricted cash (−2,245).

Figure 8. NAV/share sensitivity — WTI price × discount rate

Notes to Figure 8

1. Checksum — the bear column (US$60) at the 10% base rate: proved developed = 26,992 + 454.2 × (60.26 − 64.99) = US$24,844 m; proved undeveloped = 9,918 + 232.5 × (−4.73) = US$8,818 m; drilling inventory = 4,670 × (8,818 ÷ 1,097) × 0.25 = US$9,387 m; enterprise NAV US$43,049 m, less net debt 12,304, the Viper minority 2,650, capitalised G&A 1,211 and working capital 2,245, plus the hedge mark 219 = US$24,858 m ÷ 280.02 m = US$88.77.
2. Rate rows — they move all three carried rows and the capitalised G&A, on the 13.3-year flat-equivalent profile the standardized measure’s own discount ratio implies (×1.1145 at 8%, ×0.9030 at 12%); net debt, the hedge mark and working capital are held down each column, and the Viper minority moves with the deck and the rate on the same profile.
3. Cost — a +10% shock to the guided lease-operating and gathering costs (US$279 m/yr) takes NAV/share to US$114.92 (−4.6%); a +10% WTI move to US$77 lifts it to US$142.59 (+18.4%), and with a 5% cost lag applied to that price move, US$139.84 (+16.1%). The price line runs four times ahead of the cost line — the mark of a low-cost operator with a wide netback.
4. FX — n/a, Diamondback reports and trades in US dollars.
5. Stage risk — the only risked row is the unbooked drilling inventory, at 23% of enterprise NAV, below the 25% trigger; one band lower (0.20×) would give US$111.96 (−US$8.47), stated so the reader can see the row’s weight.
6. Schedule slip — n/a, no development asset stands outside the reserve report’s own five-year development schedule, and that schedule’s capital is already inside the standardized measure.

Figure data: this analysis’ model (Tables 8–10), every cell recomputed at that column’s WTI price and that row’s rate, never scaled from the base cell. Price columns are the fixed crude-oil grid, grid version 2026-09 (US$60–100); base case US$70 at 10%. A one-step (US$10/bbl) WTI move shifts NAV/share by US$31.66, or ~26%; the deck sensitivity is tabulated in Table 11.

Deck sensitivity — what one US$10/bbl step of WTI is worth. The grid above holds the recomputed values at each grid price; this table names the slope between them, so a reader who holds a different oil view can move the valuation themselves. Because all three reserve rows enter on the disclosure’s own linear price term and the multiples are held at their targets, the per-step figures are linear across the whole grid.

Table 11. Deck sensitivity — value per US$10/bbl step of WTI (US$/share unless stated; base rate, target multiples held)

Source: this analysis, Tables 8–10 and 18. % of base is each line’s per-step move divided by its own base-price value — a leverage read. Linear over is the WTI range on which the slope holds: ¹ the reserve leg is a fixed dollar per booked barrel, so the deck moves it only through the cycle flex of the scenario columns — the reason it is the flattest line here and the widest source of disagreement in §7.6; ² FCF/share crosses zero at ~US$30.66/bbl, far below the grid; ³ the scenario blend steps 42.80 → 42.44 → 47.29 → 52.14 because the rate and the three target multiples move with the column. Every step is the difference between two recomputed grid prices of Figure 8, never a scaled figure. Forward EBITDA moves US$1,771 m per step. How to use it: start from the base-price values (NAV/share US$120.43, blended fair value US$129.24) and add or subtract the per-step figure for every US$10/bbl of WTI away from US$70 — a US$85 flat deck gives a NAV/share of ~US$168 and a held-multiple blend of ~US$166; for a reading that also lets the multiples move with the cycle, use the scenario columns of Table 18.

P/NAV ladder (unweighted). The NAV restated as a price map, straight off Figure 8’s base-rate row: for each of the five fixed P/NAV levels this series uses for producers and E&Ps, the share price it implies at every grid price — NAV/share at the deck × level, the base rate held. Read down a column for the deck you hold, across a row for the multiple you would pay; where today’s quote sits on the map is said once, by the market-implied deck in §7.5.

Table 12. P/NAV ladder — share price implied by each P/NAV level at each grid price (US$/share)

Source: this analysis, solved on Tables 8–10: each cell is the Figure 8 base-rate NAV/share at that column’s WTI price (88.77 / 120.43 / 152.09 / 183.75 / 215.41) × the row’s P/NAV level. The levels are fixed for the series (0.50× to 1.50× in quarter steps), so two producers can be read column-for-column; Diamondback’s 0.97× target, derived in §7.3, reads US$116.82 at the base price, US$86.11 at US$60 and US$147.53 at US$80, between the 0.75× and 1.00× levels. Unweighted: it translates a multiple and a deck into a share price without reference to today’s quote, so the map stays readable as both move — parity at the base price is US$120.43, and the top of the map, 1.50× at US$100 oil, is US$323.11.

7.3 Relative valuation

At US$199.22 and 280.02 million shares, Diamondback’s market capitalisation is ~US$55.8 billion and enterprise value ~US$68.1 billion. This section values Diamondback standalone: each target multiple is the fixed anchor for the E&P-producer archetype moved by the signed drivers this post’s own scorecard has already scored. No peer multiples are tabulated here — reading Diamondback against the Section 2.8 peer set on observed multiples is the job of the sector comparison , on one shared basis. Forward metrics are struck on the FY2026 guidance year at the base deck. The US$70 base sits 11.5% below WTI’s five-year average of US$79.08 (September 2021–August 2026, on the EIA monthly series) — inside the ±25% band that marks a cycle extreme — so the subject is treated as near mid-cycle, and the scenarios in §7.6 flex the deck and the multiples together.

Table 13. Target-multiple driver line (one line, applied to every multiple)

Source: this analysis; each term is tied to one scored dimension, capped at ±10%, and no fact is charged under two labels. The driver set is the standard one — asset quality, cost position, reserves and replacement, balance sheet and capital allocation, jurisdiction; growth, management and ESG (Dims 4, 7 and 9) sit outside it and are scored in Section 9. The reserves term charges the short life and the revision record once; the drilling inventory is not haircut a second time in Table 9, where its own factor already sits at the band ceiling. The one line is applied, unchanged, to every anchor:

Target P/NAV = 0.80× anchor × 1.21 = 0.968 → 0.97× · Target EV/EBITDA = 5.0× anchor × 1.21 = 6.050 → 6.1× · Target EV per proved boe = US$10.00 anchor × 1.21 = US$12.100 → US$12.10. Rounded figures are the ones used in every table below.

Table 14. Forward EBITDA build — FY2026 guidance year at the base deck

Source: this analysis; volumes, unit costs, interest, tax and capital per the Diamondback Q2 2026 results guidance table, 3 August 2026; minority distributions per the FY2025 10-K and the Q2 2026 cash-flow statement. “Forward” is the next twelve months = the FY2026 guidance year; the volume ties to guidance with nothing added above it, and every trailing line in the free-cash-flow memo sits on the same year — FY2025 for the minority distributions, the 2026 guidance table for interest, tax and capital. The build is consolidated, so it carries Viper’s contribution — and the bridge beneath the multiple removes the 57% outside share on the company’s own disclosed split (the Q2 2026 non-controlling adjustment of US$391 m against US$3,940 m of consolidated adjusted EBITDA, 9.92%). Reconciliation: run at the second quarter’s actual volumes and realisations this build gives US$4,786 m of hydrocarbon revenue against the US$4,786 m the company reported, and US$3,817 m of EBITDA against the reported US$3,940 m of consolidated adjusted EBITDA — a 3.1% difference, the equity-method and other items the build does not carry. Cost-basis note: the NAV rows use the reserve report’s own production costs with gathering netted inside its price line, while this build states gathering separately — a definition, not a gap.

Table 15. Relative valuation — implied value per share (base case)

Source: this analysis; archetype anchors (E&P: P/NAV 0.80×, EV/EBITDA 5.0×) per the valuation guide linked in §7, “The valuation toolkit”. The implied EV crosses the same claims as the NAV bridge — plus the US$542 m asset-retirement obligation, which the reserve report carries inside its development costs but EBITDA does not — and omits only the capitalised corporate G&A, which is already deducted inside the EBITDA build. The Viper minority is bridged at 9.92% of the implied enterprise value less Viper’s own net debt, on the company’s disclosed EBITDA split. Values computed on unrounded inputs. To run the same reserve and cash-flow multiples across every North American upstream name, screen the sector on Metal Pilot.

The two reads do not agree, and the gap is the valuation: US$178.76 against US$116.82, a factor of 1.5. It is the difference between capitalising one year of cash flow and discounting a finite, audited reserve book. The multiple sees US$11.6 billion of EBITDA and applies a mid-cycle anchor; the NAV sees 3,618 mmboe of proved reserves that run under a decade at the guided rate, charges the US$9.4 billion of future development capital the reserve report schedules, prices the unbooked inventory at a quarter of in-plan value, and stops. Diamondback spends US$3.9 billion a year — a third of that EBITDA — to hold production flat, and the multiple charges none of it. That is the standard trap in valuing a high-decline shale producer on EBITDA, and it is why the NAV anchors the blend at 45%.

7.4 Further weighted methods — EV per proved boe

The third weighted read prices the booked reserve base at the archetype’s reserve anchor moved by the same driver line, and bridges it on the same claims.

Table 16. EV per proved boe build — base case

Source: this analysis; reserves per the Diamondback FY2025 Form 10-K Note 18; the bridge lines as Table 10. Basis note: the archetype’s reserve anchor is written for 2P reserves and this denominator is SEC proved (1P), the only category the filer publishes — so the method reads low by whatever the probable tranche is worth, and the unbooked inventory it cannot see is priced separately in Table 8’s third block.

The method lands at US$92.19, the lowest of the three and 29% below the blend. It is doing something the other two cannot: pricing the booked barrels at a dollar-per-barrel convention rather than at a cash-flow multiple or a discount rate. The market pays US$18.82 per proved boe against that US$12.10 target — a 56% premium — and the whole bull case for the shares is that the premium is what the unbooked inventory is worth. Table 8 prices that inventory explicitly, at the top of its band, and still reaches US$42.36/share.

7.5 Cross-checks (unweighted)

Eight diagnostics locate the blend; none carries weight.

Table 17. Cross-checks — reported, reconciled, never weighted

Source: this analysis; the market-implied and flip prices solved on the Tables 8–16 model; reserve, cost, capital and roll-forward figures per the Diamondback FY2025 Form 10-K (Items 1 and 2, Note 18); WTI history per the U.S. EIA Cushing monthly series, five-year window September 2021–August 2026; the 2027 Brent forecast per the EIA Short-Term Energy Outlook , 11 August 2026; the trailing multiple and dividend-yield series, consensus and analyst count per stockanalysis.com , read 7 September 2026 on the 4 September close. The recycle ratio runs on a two-year average because the capital table in the source set carries two years.

7.6 Scenarios & fair value

Every weighted method is re-run in every column of the WTI grid — the same five grid prices as Figure 8 and Table 11, so the whole section reads on one price axis. Each column is its own world, and Table 18 lists what changes in it above the values it produces: the deck moves one step at a time; because the base sits inside 25% of crude’s five-year average (§7.3) the subject is near mid-cycle, so the three target multiples step ×0.90 / — / ×1.10 / ×1.20 / ×1.30 with the deck; the discount rate steps out to 12% on the downside and holds at the 10% convention on the upside — a rate below the industry’s own floor would price a single-basin, sub-ten-year shale book as safer than the industry treats it at any price. The last memo row is the same blend with the multiples held at their targets, which is the linear version a reader can reproduce from Table 11.

Table 18. Scenarios & fair value — inputs, value per method and the blend by grid price (US$/share)

Source: this analysis; weights per §7.1, scenario names by offset from the base price — the base sits on the grid’s second column, so the scenario names read Bear through Extreme Bull. Base blend on a calculator: 0.45 × 116.8181 + 0.30 × 178.7553 + 0.25 × 92.1896 = 52.5681 + 53.6266 + 23.0474 = US$129.24. The unrounded method values are printed here because the blend is computed on them: from the two-decimal figures in the rows above the contributions round to 52.57 + 53.63 + 23.05 = US$129.25, one cent higher. Inputs behind the rows, by column: the flexed targets 0.87× · 5.49× · US$10.89 / 0.97× · 6.1× · US$12.10 / 1.07× · 6.71× · US$13.31 / 1.16× · 7.32× · US$14.52 / 1.26× · 7.93× · US$15.73; forward EBITDA US$9,877 m / 11,649 m / 13,420 m / 15,191 m / 16,963 m; the Viper minority US$2,304 m / 3,126 m / 3,602 m / 4,079 m / 4,555 m; cash tax US$932 m / 1,296 m / 1,659 m / 2,022 m / 2,385 m. Risk weights are 1.00 on every reserve row and 0.25 on the drilling-inventory row in every column — nothing in the model is pre-production, and the inventory factor already sits at its band ceiling. The reserve leg does not move with the deck and is held to the multiple flex: it prices a fixed booked volume at a fixed mid-cycle dollar per barrel, so the cycle enters it through the multiple rather than through the price. The hedge mark is held at +US$219 m in every column: the book is long puts struck at US$50.00–55.00 (31 July 2026 schedule), out of the money at every price on this grid, so its intrinsic value is zero in all five and only the deferred premium moves — the whole balance bounds the omission at ±US$0.78/share. Illustrative scenarios, not forecasts.

Figure 9. Value per share by method and scenario

Source: Table 18; each cell recomputed at its column’s deck, rate and multiple flex, never scaled; data-level ranked 0–9 across the whole grid. The three methods fan rather than cluster, and the fan is the finding: the cash-flow read carries the steepest deck leverage because nothing stands between EBITDA and the equity except fixed claims; the NAV is next, because it charges the development capital and terminates at the end of the book; and the reserve read is nearly flat, because a fixed dollar per booked barrel does not care what the barrel sells for. Current share price US$199.22 (4 Sep 2026); market-implied deck ~US$98.86/bbl WTI. The bracketed figure under each value is its change against the same row’s base-case value.

Conclusion. The blended base-case fair value is US$129.24, inside a US$86.44 (Bear, US$60) – US$271.12 (Extreme Bull, US$100) range, against a US$199.22 price — an implied −35.1%, Overvalued, published as Overvalued “(wide band)” because the bear-column blend sits 57% below the price. At the base price the guidance-year free cash flow of US$5,674 m after all capital and minority distributions is a 10.2% yield on the US$55.8 bn market capitalisation — a genuinely good number, and the reason the cash-flow leg is the highest of the three. Rating-flip prices: with the multiples held at their targets, the base blend crosses up into Modestly overvalued above ~US$74.21/bbl WTI (+6.0% from the base price) and into Fairly valued above ~US$90.64 (+29.5%); Overvalued is the bottom band, so no downward flip exists. That first number is the important one: the read is six dollars of oil away from changing, which makes this a conviction about the deck far more than about the company.

The three methods do not cluster, and the spread is explained rather than averaged away: the EV/EBITDA read (US$178.76) is 53% above the NAV (US$116.82) and 94% above the reserve read (US$92.19), because a whole-company multiple capitalises one guidance year and charges neither the US$9.4 billion of scheduled development capital nor the fact that the booked base runs 9.9 years at the guided rate. The NAV anchors the blend for that reason. The framing that matters is not that Diamondback is a poor business — on the operating evidence it is among the best in North American shale, with the lowest cash cost in its peer group, a 4.0× recycle ratio and the best oil-and-gas jurisdiction on earth. It is what the price now requires: the producing base plus the whole bridge is worth US$38.28/share, the booked undeveloped tranche another US$39.79, the 5,297 unbooked locations a further US$42.36 at the top of their band — and a buyer at US$199.22 is paying a US$79 premium to all three for WTI at ~US$99 held flat in perpetuity, at a moment when the EIA expects Brent back at US$69 in 2027 as the Hormuz disruption unwinds. That may happen. The reserve report, which is audited and dated, prices none of it. The Street’s US$232.54 target underwrites more still. This is an analytical read of price against value, not a recommendation.

Assumptions box: valuation date 7 September 2026; balance sheet as of 30 June 2026 for net debt and shares, 31 December 2025 for the derivative, working-capital and asset-retirement lines (the latest in the source set); horizon spot fair value. USD throughout — trading currency = model currency, no FX. Price decks: base WTI US$70/bbl (the 12-month trailing average of US$75.87 to end-August 2026, leaned to the lower price of the fixed grid because the window carries the March–May 2026 Hormuz spike; 3-month US$83.06, 6-month US$90.50), run across the US$60–100 grid, version 2026-09, with the base on the grid’s second column; the EIA’s US$69/bbl Brent forecast for 2027 as a 0% cross-check — no spot deck is carried; gas at Henry Hub US$3.00/MMBtu and, in the model, at the reserve report’s own US$1.32/Mcf realisation; constant-price, unescalated deck and costs, matching the SEC reserve convention, so the 10% rate is real. Discount rate 10% — the E&P convention for a single-basin, high-decline base with a 9.9-year proved life, and the rate the standardized measure is struck at — sensitised 8–12% on the reserve rows and the capitalised overhead; no jurisdiction premium (Dim 8 ★★★★★, 100% United States, so the band is +0%). Share basis 280.02 m (basic = diluted on the company’s two-class computation); values per share to two decimals, multiples to two significant figures, on unrounded inputs. Cycle: base 11.5% below the five-year average of US$79.08 (Sep 2021–Aug 2026), inside ±25%, so deck and multiples flex together across the scenario columns; anchors E&P P/NAV 0.80×, EV/EBITDA 5.0×, EV per reserve boe US$10.00 per the valuation guide linked in §7, one driver line (×1.21); metric basis forward FY2026 (guidance year); EBITDA before all capital and after cash G&A; net debt on the company’s own definition, leases excluded and n/d; P/NAV form equity (market cap ÷ equity NAV); no peer multiples enter this section. Method weights NAV 45% / EV/EBITDA 30% / EV per proved boe 25% — the E&P default, no deviation. NAV provenance: Diamondback’s own disclosed after-tax standardized measure, apportioned on the filing’s own volumes and prices and moved to the deck on a term built from its oil volumes, production-tax ratio and discount ratio; the drilling-inventory row author-built from filed location counts at the de-risking band ceiling; tax basis the SEC schedule (basis 3), pools inside it; abandonment inside the reserve report. Primary value yardstick P/NAV (equity form). Stage-risk placement: the drilling-inventory row weight, 0.25× (derived 0.36, capped at the band ceiling); every reserve row at 1.00; the target P/NAV and the discount rate carry no second charge. Known data gaps: (1) lease liabilities n/d — the balance sheet carries no separate lease caption and the source set no lease-liability balance, so leases are charged once inside the reserve report’s production costs, bound by the US$625 m “other long-term liabilities” caption; (2) the 30 June 2026 derivative asset n/d — only the US$36 m current derivative liability is separately disclosed at that date, so the hedge line is the 31 December 2025 net mark of +US$219 m, bound at US$0.78/share and closed by the Q2 2026 Form 10-Q; (3) investments and other assets n/d — the US$796 m “other assets” caption is not disaggregated, NAV understated, bound US$2.84/share; (4) the maintenance/growth capital split n/d — the whole US$3.9 bn programme is treated as maintenance, which understates free cash flow before growth capital; (4a) the gas realisation is held at the reserve report’s own US$1.32/Mcf while the second quarter of 2026 realised negative US$2.15/Mcf on Waha constraints — the company publishes no forward gas realisation, so the report’s price stands; direction: net asset value and forward EBITDA overstated, bound US$1,733 m of forward revenue, about US$4.8/share of blended fair value, closed by a guided gas realisation or a full year at the current basis; (5) a dated EV per flowing boe/d anchor n/d — the diagnostic is printed unweighted in §7.5 rather than carried as a method. None changes the rating. To run the same net asset value and multiples across every North American upstream name, screen the sector on Metal Pilot.

8. Near-term catalysts (1–3 years)

Diamondback’s forward upside over the next two to three years is mostly already contracted and self-funded — the job is to convert scale and low cost into deleveraging and per-share growth, not to chase volume. The most material positives are structural, not speculative.

The common thread is self-funded, low-cost catalysts: Diamondback does not need higher oil to deleverage, integrate or grow the dividend — a firm tape simply accelerates all three. The swing factor is execution and the oil price, not access to capital.

9. Rating & verdict

Diamondback is scored on the Metal Pilot Company Scorecard — the same nine dimensions, on the same ★1–5 scale, that every US upstream name in the series is scored on, so the peers are directly comparable. Each star is relative to the large-cap Permian-weighted E&P peer set and substantiated below.

Table 20. The Diamondback scorecard

Source: the Metal Pilot Company Scorecard; evidence in Sections 2–7. Peer basis: large-cap Permian-weighted US independent E&Ps. Composite is the archetype-weighted average per Table 2 of the Metal Pilot Company Scorecard playbook (producer/operator weighting: dims 1/2/3/5/6 at 15% each, dims 4/7/8/9 at 6.25% each).

Weighted average = (0.75 + 0.75 + 0.60 + 0.45 + 0.60 + 0.25 + 0.25 + 0.3125 + 0.25) = 4.21/5 → rounds to the published ★★★★, Solid.

The two-axis verdict. Quality Solid (★★★★) × Value Overvalued (wide band) → a great company at a rich price: watch for a better entry. The quality axis is durable and genuinely high — elite assets, elite cost and the best jurisdiction on earth (three ★★★★★s) — held back only by an acquisition-swollen balance sheet and the inescapable fact that it is a single-commodity, single-basin price-taker. The value axis is the dated, oil-dependent layer, and it has moved: on the base deck of US$70/bbl the blended fair value is US$129.24 against a US$199.22 price, an implied −35.1%, and the market-implied read says the shares discount a flat WTI of about US$98.86 — 25% above crude’s own five-year average and US$30 above the EIA’s US$69/bbl Brent forecast for 2027. The target multiples the module argued are a premium to their archetype anchors, not a discount (P/NAV 0.97× against a 0.80× anchor, EV/EBITDA 6.1× against 5.0×, EV per proved boe US$12.10 against US$10.00) — the quality is credited, and the price still runs ahead of it. The read carries the wide-band qualifier because the bear column blends 57% below the price, and it flips up into Modestly overvalued on only US$4/bbl more oil (US$74.21). What tips the verdict is not the assets — those are settled — but the deck, and the deck the shares capitalise is a conflict price. This is an analytical read, not a recommendation.

10.1 Sources, methodology & data vintage

Company fundamentals, structure, management, hedge posture, reserves and per-segment detail are from Diamondback Energy, Inc. — 10-K Filing / Annual Report — 2025 (fiscal year ended 31 December 2025), the Q4/FY2025 results release (23 February 2026) and the Q1 2026 results release (4 May 2026), plus the 2025 Corporate Sustainability Report for the ESG figures. Market data (share price US$199.22, 280.02 million shares, market cap ~US$55.8 billion) and analyst figures (30-analyst consensus target US$232.54, Buy) are as of the 4 September 2026 close, per stockanalysis.com , read 7 September 2026. Enterprise value, EV/EBITDA and free-cash-flow yield are derived from those inputs. The Section 7 valuation is built on the company’s own disclosed after-tax standardized measure at 31 December 2025 (Note 18), apportioned into its developed and undeveloped tranches on the filing’s own volumes and prices and moved to the stated deck, plus an author-built drilling-inventory row from the filed location counts; the price deck is the fixed US$60–100 WTI grid on the U.S. EIA Cushing monthly series, with the EIA Short-Term Energy Outlook of 11 August 2026 as the unweighted forecast cross-check. Section 7’s data-gap register names five inputs the source set does not carry; the two that would most improve the valuation are the Q2 2026 Form 10-Q (the 30 June 2026 derivative, lease and other-asset balances) and the company’s 2026 corporate presentation (the maintenance/growth capital split). Peer figures in Section 2.8 are approximate and flagged for refresh at publish. The asset map is omitted deliberately — a single contiguous Permian position does not render as a legible proportional-symbol map. Data as of 7 September 2026; refreshed on each annual report and on material events. Re-run log — 7 September 2026: Section 7 rebuilt on the reserve-based method against the FY2025 10-K and the Q2 2026 results, and the market layer rolled to the 4 September close; net asset value US$120.43/share, blended fair value US$129.24, value read Overvalued (wide band), replacing the earlier corporate free-cash-flow model and its fairly-valued read. Provenance: Diamondback Energy, Inc. — 10-K Filing — 2025.
