DuPont de Nemours, Inc.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 1,215 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• SHARE BASIS, the dominant risk for this company. DuPont effected a 1-for-3 reverse stock split of its common stock, effective 24 Jun 2026 (announced 26 May 2026), which reduced authorized shares from approximately 1.7 billion to 556 million and retroactively restated all share and per-share figures in the Q2 2026 10-Q. Separately, on 1 Nov 2025 DuPont completed the Electronics Separation: the spin-off of its semiconductor and interconnect solutions businesses into an independent public company, Qnity Electronics, Inc. ('Qnity'), via a pro rata distribution to DuPont stockholders of record as of 22 Oct 2025. The Qnity spin-off did not itself change DuPont's own share count (it was a distribution of Qnity shares, not a change to DuPont's share structure), but it did remove the Electronics segment from DuPont's continuing operations (reported as discontinued operations in all periods). The current, single-class share count used throughout this file is 135,042,975 shares outstanding at 31 Jul 2026 (Q2 2026 10-Q cover page), which is POST the 24 Jun 2026 reverse split.
• Register basis handling. All institutional 13F filings used here are for the quarter ended 30 Jun 2026, filed in Aug 2026, i.e. AFTER the 24 Jun 2026 reverse split took effect within that same quarter. Checked directly: every 13F filer's implied price per share (value_usd / shares) clusters tightly around $135.6 to $135.7, matching DuPont's actual post-split trading range, and all use the same CUSIP 26614N201, confirming these are already reported on the post-split basis with no restatement needed. The one exception found was T. Rowe Price Associates, Inc., which reports values in THOUSANDS (see its row's method_note): its raw implied price was approximately $0.136 per share, corrected by multiplying value by 1,000.
• The 2026 DEF 14A (filed 10 Apr 2026, ownership table as of 7 Apr 2026) predates the 24 Jun 2026 reverse split, so its own share counts (409,877,186 total shares outstanding, and every individual director/officer figure) are on the PRE-split basis. For the three insider rows drawn from this proxy (Breen, Koch, the 16-person group), shares were restated to the post-split basis by dividing by 3 and rounding to the nearest whole share; pct_of_company was left as the proxy's own as-filed ratio (numerator and denominator both pre-split), which a split does not change. The proxy's own 'Certain Other Owners' figures for Vanguard (48,043,862 shares, 11.72%, pre-split) and BlackRock (30,389,248 shares, 7.41%, pre-split) are NOT used in the register: the directly sourced Q2 2026 13F filings above are more current (30 Jun 2026 vs a stale 13G/13D reference date implied by the proxy footnotes) and are already on the correct post-split basis.
• Aramids Divestiture (asset sale, not a DuPont share-structure change). On 1 Apr 2026 DuPont completed the sale of its Aramids business to Arclin (a portfolio company of TJC LP) for approximately $1.2 billion cash, a $300 million note receivable, and a roughly 16 percent non-controlling equity interest in New Arclin U.S. Holding Corp, now recorded as a holding in this file.
• Holdings side. DuPont's Q2 2026 10-Q, Note 10 (Nonconsolidated Affiliates), states the Company held an ownership interest in three nonconsolidated (equity-method) affiliates at 30 Jun 2026, with net investment totaling $458 million (up from $111 million at 31 Dec 2025, before the Aramids Divestiture closed). Two are individually named and sized in the filing text: New Arclin U.S. Holding Corp (Arclin, approximately 16 percent, $325 million carrying value) and Derby Group Holdings LLC (19.9 percent, $132 million carrying value, received in the November 2023 Delrin divestiture). These two sum to $457 million, approximately the full $458 million total; the identity and size of the third, much smaller affiliate is not disclosed and is left null (see unknowns). Because each of the two named investees has its own individually disclosed carrying value in the filing text (not a single undifferentiated combined-bucket figure), both are sized rather than left null.
• No overlap found with Dow Inc. (researched separately as data/research/dow.json, which carries nine private petrochemical joint ventures in Kuwait and Thailand: EQUATE, Kuwait Olefins, Kuwait Styrene, Map Ta Phut, Sadara, Siam Polyethylene, and three SCGC-Dow entities). DuPont's two disclosed nonconsolidated affiliates, Arclin (materials/coatings, US) and Derby Group Holdings LLC (ex-Delrin acetal business), are unrelated ventures with different counterparties; despite the shared DowDuPont corporate ancestry (both companies emerged from the 2019 DowDuPont three-way separation into Dow, Corteva and the current DuPont), no shared joint venture was found between the two files.
• No strategic (Schedule 13D) holder was found. DuPont's EDGAR filing history shows only Schedule 13G filings (passive, most recent 2024) for this issuer, no 13D or 13D/A, consistent with an index/institutional-dominated register and no activist or founder-controlled block.
• Heritage note, immaterial in size. One current director, Eleuthere I. du Pont (President, Longwood Foundation), is a descendant of the company's founding family. His personal proxy-reported stake (51,578 shares pre-split, 1,920 owned outright plus 49,658 rights to acquire, about 0.0126 percent of the company) is far too small to be a controlling or strategic position and is not broken out as its own register row; it rolls up into the officers-and-directors group residual along with the other 13 non-Breen, non-Koch members.
• State Street Corporation (CIK 0000093751) filed a Q2 2026 13F-HR but its information table (checked directly, all 4,177 rows) contains no row for DuPont (CUSIP 26614N201, searched by 'DUPONT' and 'PONT' fragments), so no State Street row appears in this register. This is treated as a sourced absence for this filing entity rather than a gap, though State Street may hold DuPont shares through a different registrant not checked here (see unknowns).
• Capital Group family (Capital World Investors CIK 0001422849, Capital International Investors CIK 0001562230, Capital Research Global Investors CIK 0001422848) and T. Rowe Price Investment Management, Inc. (CIK 0001897612) were each checked and hold zero DuPont shares in their Q2 2026 13F-HR filings (full info table searched for a 'DUPONT' fragment, no match in any of the four). No rows for these entities appear in the register as a result.
• Register self-gate, computed the way the chart computes it: 9 register rows (6 institutional 13F rows, 2 individually named insiders, 1 insider aggregate group). members = {'All Directors and Executive Officers as a Group (16 persons)': 166,910 (Koch) + 853,493 (Breen) = 1,020,403}. Group's own raw shares (1,306,528) reduced to its residual (1,306,528 - 1,020,403 = 286,125); all other rows counted at full value. Total = 15,340,961 (Vanguard) + 10,637,868 (BlackRock) + 3,747,286 (Geode) + 1,275,087 (T. Rowe) + 920,190 (Norges Bank) + 851,583 (FMR) + 853,493 (Breen) + 166,910 (Koch) + 286,125 (group residual) = 34,079,503 shares against 135,042,975 shares outstanding = 25.24 percent. This sits at the low end of, but within, the expected 25 to 45 percent band; the register is index-and-insider heavy and omits several active managers (State Street returned no holding, and other funds were not individually checked), which plausibly explains the low-end result rather than indicating a basis error, since every individual row's implied price per share was cross-checked against the current post-split trading range.
• Market capitalization ($18.76 billion) and share price ($138.95) are from stockanalysis.com as of 18 Aug 2026, 11:45am ET. Cross-check: 135,042,975 shares x $138.95 implies approximately $18.76 billion, consistent with the reported market cap and with stockanalysis.com's own directly reported figure.
