Host Hotels & Resorts, 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 678 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

• UPREIT structure: Host Hotels & Resorts, Inc. (CIK 0001070750, this file's subject) is the general partner and owns approximately 99% of Host Hotels & Resorts, L.P. (a separate SEC registrant that co-files the same combined 10-K/10-Q), which conducts substantially all of the operating business. Host L.P. common operating partnership (OP) units are NOT Host Inc. common shares; each OP unit is redeemable for cash or, at Host Inc.'s election, for Host Inc. common stock at a conversion ratio of 1.021494 shares per unit. Per project rule, every register row here reports Host Inc. COMMON SHARES ONLY; where a holder (Richard E. Marriott) also holds OP units, those units are excluded from the shares field and stated separately in method_note. company.shares_outstanding (685,124,399) is taken from the Host Inc. common stock cover-page count in the combined Q2 2026 10-Q, dated 5 Aug 2026, not from any Host L.P. unit count.
• Joint ventures: searched the newest 10-K (FY2025, filed 25 Feb 2026) and newest 10-Q (period 30 Jun 2026, filed 7 Aug 2026) in full for 'joint venture', 'equity method', 'unconsolidated', and 'investments in affiliates'. The FY2025 10-K's Investments in Affiliates note carries a named, per-entity table (Maui JV, Hyatt Place JV, Harbor Beach JV, Philadelphia Marriott Downtown JV, Noble JV, Fifth Wall Ventures, Other investments) with individual ownership percentages and carrying values as of 31 Dec 2025, all recorded as holdings above except 'Other investments' ($9 million combined, covering unnamed minor items, left out per the rule against assigning a combined balance to one investee; see unknowns). The newer Q2 2026 10-Q does NOT repeat this per-entity table: it discloses only a combined balance-sheet line ('advances to and investments in affiliates', $299 million as of 30 Jun 2026) and a separate VIE-only disclosure (three unconsolidated partnerships, 11%-30% LP interests, combined $164 million carrying value), neither of which can be split to update any single named JV past 31 Dec 2025 without inventing a number. The FY2025 10-K's Exhibit 21 subsidiaries list was NOT separately checked for an ownership-percentage column since the Investments in Affiliates note already provides named, percentage-sized entities directly.
• The unverified lead mentioned a 'European joint venture'. None was found: the only foreign JV disclosed in the FY2025 10-K is the 'Asia/Pacific JV', a 25% interest (implying a 36% interest in seven hotels and an office building in India) with RECO Hotels JV Private Limited, which Host EXITED during 2025 (per the 10-K: 'representing our exit from our Asia investment', with proceeds of approximately INR 1,550 million / $17 million and a roughly $1 million recorded loss on sale). Per the project's rule that an exited holding is a note rather than a row, this Asia/Pacific JV is recorded here only, not as a holdings entry, and it is absent from the 31 Dec 2025 Investments in Affiliates table (confirming the exit). The two Hyatt-related ventures from the unverified lead (Maui JV / Hyatt Residence Club at Maui, and Hyatt Place JV / Hyatt Place Nashville Downtown) ARE confirmed and included above.
• Register self-gate, computed on this final file using the project's exact chart formula (container reduced to its residual, members counted at full value, everything else at full value): 14 rows, share total 387,780,497, 387,780,497 / 685,124,399 = 56.60% of company. This is slightly above the project's stated typical range (25%-45%, flag above 55%). Investigated for a double-count or mixed instrument and found none: every institutional row (11 of the 14) was independently fetched from that filer's own fresh Q2 2026 13F-HR, grouped strictly by CUSIP 44107P104 by scripts/filing.py, and cross-checked for implied price consistency (value_usd / shares); all but three cluster tightly around $23.71/share (State Street $24.62 and JPMorgan $24.96 are modestly higher but internally consistent across each filer's own multiple lines, plausibly a different intra-quarter valuation date/feed, not a units error). Host Hotels is a large, heavily institutionally-held S&P 500 REIT; its top 11 institutional holders alone summing to 55.1% of the company is high but not implausible given how index-fund-heavy the REIT sector is and how large Vanguard (16.08%) and BlackRock (12.90%) are on their own. The two named insiders (Richard E. Marriott, James F. Risoleo) and the officers/directors aggregate add a further 1.5% with the container correctly reduced to its 12-person residual (2,237,798 shares) to avoid double counting the two members broken out individually.
• Three filers on this CUSIP report their 13F information-table VALUES IN THOUSANDS rather than whole dollars, confirmed by the implied-price check (each raw implied price was approximately $0.0237/share versus the approximately $23.71/share baseline seen on every other filer for the same CUSIP and quarter; multiplying the filed value by 1,000 restores the consistent implied price): Cohen & Steers, Inc. (as flagged in the project brief for this company specifically), T. Rowe Price Associates, Inc., and SG Americas Securities, LLC. All three are corrected (x1000) in this file; T. Rowe Price's position (934,115 shares, approximately 0.14% of the company, corrected value approximately $22,148,000) is too small to place in the top-12 register and is not included as a row, but is recorded here since checking it was part of the T. Rowe Price protocol.
• Capital Group family checked and found to hold NOTHING in Host Hotels for Q2 2026: Capital World Investors (CIK 0001422849), Capital International Investors (CIK 0001562230), and Capital Research Global Investors (CIK 0001422848) were each independently fetched from their own fresh Q2 2026 13F-HR information tables and none contains a row for CUSIP 44107P104 / Host Hotels. This is recorded as a note per the project's rule that a checked-and-zero holder is a note, not a null row.
• T. Rowe Price checked on both registrants per the project's protocol. T. Rowe Price Associates, Inc. (CIK 0000080255) holds 934,115 shares (see the thousands-correction note above); T. Rowe Price Investment Management, Inc. (CIK 0001897612), the separate registrant sometimes named as the 5% holder in other companies' proxies, holds NOTHING in Host Hotels for Q2 2026 (0 matching rows in its own fresh 13F-HR). Neither entity is large enough to place in the top-12 register.
• market_cap_usd is derived from company.shares_outstanding (685,124,399, as of 5 Aug 2026 per the 10-Q cover page) multiplied by the last Nasdaq trade price of $23.15 on 19 Aug 2026 (Nasdaq quote API), giving 685,124,399 x 23.15 = 15,860,629,837 (rounded to the nearest whole dollar); this is a derived figure, not itself a single filed number, so it is not separately flagged as modelled since it is a standard shares-outstanding x price computation using two directly sourced inputs.
• Coordinator verification of the 56.60 per cent self-gate, which sits above the project's 55 per cent investigate-rather-than-ship line. Four independent checks were run and all four support it. First, the denominator was confirmed at source: the combined Host Inc. and Host L.P. Q2 2026 10-Q cover page states 'As of August 5, 2026, there were 685,124,399 shares of Host Hotels & Resorts, Inc.'s common stock, $0.01 par value per share, outstanding', so the figure is Host Inc. COMMON STOCK and not Host L.P. operating partnership units. Second, the instrument was confirmed: the same 10-Q states a market price per Host Inc. common share of $23.71 at 30 Jun 2026, which is exactly the implied price carried by the institutional register rows, so every 13F row is denominated in the listed common class. The 9.4 million common OP units outstanding disclosed as non-controlling interests of Host L.P. are a DIFFERENT instrument and are deliberately not in this register. Third, the individual rows corroborate against this project's own 13F-derived snapshot at data/registers/HST.json, built from 678 filers at 31 Mar 2026 and independent of the filings read here: Vanguard 109,362,820 there against 110,149,977 here, State Street 42,444,994 against 41,955,050, Cohen & Steers 55,124,367 against 44,820,149, BlackRock 77,533,617 against 88,409,556. Each curated row therefore matches a distinct filer family that an independent source also reports at that size, so the total is not a double count. Fourth, that same snapshot reports 687,582,417 shares across 678 filers, which is approximately 100 per cent of shares outstanding, so Host is close to wholly institutionally held and a top-14 concentration of 56.60 per cent is consistent rather than anomalous. The proxy aggregate was also checked: the container holds 10,287,825 shares and its two listed members, Richard E. Marriott at 5,411,733 and James F. Risoleo at 2,638,294, are correctly reduced out of it, leaving a residual of 2,237,798.
