DuPont de Nemours (DD) Economic Moat Analysis—

Competitive advantages, dated evidence and erosion risks.

Uncertain economic moat

DuPont has documented intellectual property, recognized brands and technical capabilities that support differentiation, but the passages do not establish durable competitive protection or customer dependency. Patent coverage strengthens the case for a potential moat without demonstrating its commercial exclusivity. Recent organic growth and improved aggregate profitability support current operating performance, but price and volume are combined, leaving realized pricing power unresolved. Insufficient evidence, rather than established low barriers or competitive weakness, drives the verdict.

Intangible assets

A current patent estate, recognized trademarks and application support provide credible differentiation. Their ability to sustain an economic moat remains unestablished because product-level exclusivity, substitution and customer purchasing outcomes are not disclosed.

Durability
At December 31, 2025, about 4,700 patents and applications related to continuing operations, and more than 70% of that estate had remaining terms above five years. This supports a protection runway, but patent counts and remaining terms do not establish commercially effective barriers.
Competitors
3M, Honeywell, Hydranautics, Kingspan, Kolon, Lanxess, Owens-Corning, Ecolab, Avient, Toray, Teijin, Yantai
Erosion risks
Technological substitution, limited patent scope, enforcement difficulties and competing innovation could erode differentiation. Intellectual property litigation has already generated costs; adverse litigation outcomes remain possibilities rather than demonstrated losses of commercial rights.
What would invalidate the thesis
The potential moat thesis would fail if commercially important protected products lose business to equivalent alternatives, patent expiry or adverse rulings remove effective exclusivity, or sustained price concessions and share losses show that differentiation does not influence purchasing.
Evidence (5) · Counterevidence (4)

Changes since the previous analysis

  • Retain the previous uncertain verdict and distinction between differentiation and demonstrated competitive protection.
  • Add quantified patent coverage and remaining terms, strengthening evidence of current intangible assets without establishing a moat.
  • Add actual proxy disclosures supporting assessments of incentive alignment and governance, including qualifications from early PSU conversion based on projected outcomes.
  • Identify historically disclosed competitors while qualifying their applicability after the Electronics separation and Aramids divestiture.

Evidence limitations

  • All supplied sources are issuer filings. Management statements about competitive strengths and value-in-use pricing are distinguished from reported operating results.
  • Source dates are filing dates: filing-4 was filed February 14, 2025; filing-1 February 17, 2026; filing-3 April 10, 2026; filing-6 May 5, 2026; and filing-2 August 4, 2026. They are not retrieval dates.
  • Named competitors come from the historical Water & Protection segment. Their precise overlap with today's retained businesses is not established; current competition disclosures identify only generic categories. Electronics competitors are not treated as established competitors of the retained company.
  • No product-level market shares, substitution outcomes, customer switching costs, renewal data or commercial importance of individual patents are supplied.
  • Organic sales combine price and volume. Customer agreements are mentioned without pricing reset, termination, exclusivity or pass-through terms.
  • Proxy disclosures establish actual compensation practices and governance structures, but executive beneficial ownership and compliance with ownership requirements are not supplied.
  • Portfolio changes limit historical comparability. No network effect, relative cost advantage or efficient-scale barrier is demonstrated.

Pricing power—

  • Pricing outcomes

    Reported organic growth combines selling prices and volumes. Value-in-use pricing is an issuer description, and conditional cost pass-through is not a realized pricing outcome.

  • Customer demand

    Positive organic sales indicate aggregate demand, but cannot distinguish repeat purchases from new customers or price effects. Technical service and purchase-order disclosures do not establish observed retention.

  • Margin resilience

    Comparable quarterly figures imply annual gross margin improved from about 33.5% in 2024 to 34.5% in 2025. Aggregate segment operating EBITDA increased, but Diversified Industrials declined while Healthcare & Water Technologies improved. This is mixed operating resilience; it does not isolate pricing from mix or productivity.

  • Pricing freedom

    Purchase orders sometimes operate under master supply agreements, but the passages omit price-setting, renegotiation and termination provisions. Market-sensitive pricing does not establish contractual discretion.

Management56

  • Capital discipline

    Completed divestiture proceeds, actual capital spending and completed share retirements demonstrate concrete capital actions. Material held-for-sale losses and goodwill impairments temper the record. Acquisition returns, repurchase value creation and comprehensive cash-generation coverage remain insufficient for a stronger grade.

  • Incentive alignment

    Existing ownership requirements, clawbacks, hedging restrictions and an actual performance-linked CEO payout support alignment. Early measurement of outstanding PSUs and conversion using projected performance weaken the original long-term performance test. Actual beneficial holdings and ownership compliance are missing.

  • Execution

    The Electronics separation and Aramids sale were completed, recent organic sales grew, and separation-related expenses fell. Segment profitability was uneven and divestiture-related losses were substantial. Execution is assessed from these operating and transaction outcomes, without treating management's favorable narrative or planned savings as achieved results.

  • Governance

    Disclosed stockholder rights, annual elections, independent committees, an entirely independent Audit Committee and eight actual Audit Committee meetings support strong demonstrated governance processes. The independence count for director nominees is not treated as a completed election result, and disclosed processes do not prove exceptional oversight effectiveness.

Moat—

Insufficient evidence for every rubric criterion; no category score is inferred.

structural advantage · — · Patents, brands and technical support establish differentiated assets, but their ability to exclude substitutes or protect economic returns is unresolved. The moat verdict remains uncertain.

durability · — · Remaining patent terms support a legal protection runway, but commercial relevance, enforceability and replacement by competing technologies are not established.

customer dependency · — · Technical support and management's customer-intimacy claim do not establish switching friction or dependency. Purchase orders and unspecified master agreements provide no evidence of customer lock-in.

erosion resilience · — · Organic growth supports current demand, while litigation costs show a realized burden. Neither establishes whether competitive advantages withstand substitution or pricing pressure over time.

Pricing power—

Insufficient evidence for every rubric criterion; no category score is inferred.

realized pricing · — · Reported organic growth combines selling prices and volumes. Value-in-use pricing is an issuer description, and conditional cost pass-through is not a realized pricing outcome.

Equal-weight grades: debt/FCF (1–8x), net debt/earnings before interest and tax (0–5x), interest service (1–12x), current ratio (0.75–2x). Earnings use reported operating income, or reported pretax profit plus reported interest expense when operating income is unavailable. Interest service uses earnings/interest expense; if unavailable, it uses reported operating cash flow/cash interest paid, without relabeling cash paid as accrued expense. Nonpositive cash flow/earnings score 0 for their service component; reported zero interest with a positive numerator scores 100. Net cash scores 100 for net leverage. Missing disclosures remain unavailable. General nonfinancial-company rubric, not a credit rating; exceptional and nonoperating gains are not normalized out. IFRS finance-cost and cash-flow classifications retain their reported scope.

Return uses reported operating income or, if unavailable, EBIT calculated from reported pretax profit plus reported interest expense; exceptional/nonoperating gains are not normalized out. Share-based cost uses the reported cash-flow add-back or, if absent, separately reported recognized compensation expense; the latter never becomes an FCF adjustment. Nonpositive net income scores 0 for cash conversion; absent income/FCF stays unavailable. Nonpositive invested capital has no defined return and remains unavailable. Does not establish acquisition quality or buyback timing.
