Prologis, 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 1,643 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

• Holdings scope: co-investment ventures. Prologis' Strategic Capital segment runs a large minority-stake business: 'Thirteen of the co-investment ventures are unconsolidated entities, and one is consolidated, with our ownership in the co-investment ventures ranging from 15% to 55%' (Q2 2026 10-Q). The Q2 2026 10-Q only discloses these ventures in aggregate by region (U.S., Other Americas, Europe, Asia); the FY2025 10-K (Note 4, at 31 Dec 2025, when there were 10 unconsolidated and 1 consolidated venture) is the most granular source available and names each venture individually with its own ownership percentage and investment balance, so all ten holdings rows above use FY2025 10-K figures dated 2025-12-31 rather than the less granular Q2 2026 10-Q. The FY2025 10-K's ten individual investment-balance figures sum exactly to its disclosed total ($10,263,233,000), confirming they are individually stated, not a combined estimate.
• Excluded as consolidated, not a holding: Prologis U.S. Logistics Venture ('USLV'), 55.0% owned at both 30 Jun 2026 and 31 Dec 2025. This is the ONE co-investment venture Prologis consolidates (it appears in both filings' tables of consolidated entities with noncontrolling interests, not the unconsolidated/equity-method table), so per the brief it is a controlled operating subsidiary and is excluded here. It is a distinct entity from Prologis Targeted U.S. Logistics Fund ('USLF', 31.9% owned, unconsolidated, included above); the similar names are easy to conflate but the filing treats them as separate ventures with separate accounting treatment.
• Combined balances excluded per rule against assigning a combined figure to one investee. (1) 'Other ventures' within Investments in and advances to unconsolidated entities: $811,121,000 at 30 Jun 2026 ($830,703,000 at 31 Dec 2025), per the Q2 2026 10-Q's summary table. No individual investee is named or sized for this balance in the Q2 2026 10-Q or the FY2025 10-K; no holding is recorded for it. (2) The Q2 2026 10-Q reports the unconsolidated co-investment ventures balance grew to $10,656,282,000 at 30 Jun 2026 (from $10,263,233,000 at 31 Dec 2025) across 13 named-in-aggregate ventures, but does not break the increase or the new total out by individual venture; the ten FY2025 10-K rows above are not restated to this later combined total, and the gap between them (three ventures formed in H1 2026, plus growth in the ten named ones) is listed in unknowns rather than estimated.
• FIBRA Prologis unit count (567.4 million CBFIs) is recorded as shares per the brief's explicit allowance, clearly labelled as CBFI units and distinct from Prologis, Inc. common stock; the same applies to the Nippon Prologis REIT and China AMC Prologis Logistics REIT (Prologis C-REIT) unit counts, the other two of Prologis' three publicly traded sponsored vehicles.
• Market value vs equity-method carrying value for the three publicly traded vehicles. This file reports value_usd as shares x the filing's own disclosed USD closing price for FIBRA Prologis, NPR and Prologis C-REIT (a market value), which is higher than each entity's separately disclosed equity-method 'Investment in and Advances' carrying value at the same date (FIBRA Prologis: $982,538,000 carrying vs $2,383,080,000 market value; NPR: $540,408,000 vs $770,848,000; Prologis C-REIT: $72,314,000 vs $68,060,000, roughly consistent). The gap for FIBRA Prologis and NPR reflects equity-method historical cost accounting versus current market price; see each holding's method_note.
• Register reconciliation on Vanguard, BlackRock and State Street. Prologis' 2026 proxy statement (record date around 6 Mar 2026, citing the most recent Schedule 13G filings) reports The Vanguard Group, Inc. at 119,484,352 shares (12.93%, per a 13G/A filed 13 Feb 2024), BlackRock, Inc. at 86,220,147 shares (9.3%, per a 13G filed 17 Jul 2025), and State Street Corporation at 62,014,856 shares (6.71%, per a 13G filed 30 Jan 2024). The register instead uses each manager's Q2 2026 Form 13F-HR (30 June 2026 position date): Vanguard's successor entities sum to 116,160,233 shares, BlackRock reports 103,392,538 shares, and State Street reports 55,915,113 shares. All three are lower than the stale 13G figures cited in the proxy, plausibly reflecting a combination of portfolio changes and, for Vanguard specifically, the disaggregation of its 13F reporting structure since January 2026 under which subsidiaries that formerly rolled into the parent's beneficial ownership now report separately (see the Vanguard row's own method_note for the case classification).
• Thousands-convention check. Implied price per share (value_usd / shares) was computed for every institutional register row: Vanguard, BlackRock, State Street, FMR, Morgan Stanley, Northern Trust, Bank of America, Capital Research Global Investors and Capital International Investors all cluster tightly at $135.47/share for the same 30 June 2026 date; Geode is close at $134.94/share; JPMorgan is somewhat higher at $138.90/share (plausibly a slightly different intra-quarter weighted mix, not a units error, since 24 lines were summed with no derivative lines excluded incorrectly). Cohen & Steers' raw XML value implied $0.1354/share, about 1000x low; it is rescaled per its own method_note and reconciles to $135.47/share, matching the cluster exactly. No other filer showed a comparable discrepancy.
• Percentages in the register (other than the insider row, which uses the proxy's own stated percentage per its method_note) are computed by this research against 933,076,000 common shares outstanding as of 24 July 2026 (Q2 2026 10-Q cover page: 'The number of shares of Prologis, Inc.'s common stock outstanding at July 24, 2026, was approximately 933,076,000'). The 10-Q balance sheet separately shows 933,006,000 shares issued and outstanding at 30 June 2026 (in thousands), consistent with the cover-page figure to within normal share issuance between the two dates.
• Market cap and shares-outstanding discrepancy. stockanalysis.com reports 969.49 million shares outstanding and an implied market cap of $135.75 billion as of 17 Aug 2026, both higher than this file's SEC-sourced 933,076,000 shares outstanding. market_cap_usd here (130,659,033,520) is instead calculated as 933,076,000 x the stockanalysis.com last price of $140.02 on 17 Aug 2026, using the SEC-filed share count for internal consistency with shares_outstanding above; the aggregator's own larger share count and market cap are not used and the discrepancy is unresolved (possibly a stale or differently defined aggregator share count; not investigated further within budget).
• Prologis, L.P. (the operating partnership) has its own outstanding common limited partnership units, separate from Prologis, Inc. common stock; none of the register rows above are OP-unit positions, so none required a shares:null OP-unit treatment on the register side. The one place OP units appear is inside the insider aggregate row's excluded 2,750,092 convertible-units/awards figure, handled per its method_note.
• Self-gate check: summing the eleven non-insider institutional register rows (Vanguard through Bank of America) plus the insider aggregate row (12 rows total) gives 418,775,397 shares against 933,076,000 shares outstanding, or 44.9%, within the expected 25 to 45 percent range.
