KKR & Co. 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 1,255 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

• The 13F exclusion, the KKR case. KKR's registered investment adviser, Kohlberg Kravis Roberts & Co. L.P. (CIK 0001399770), together with two other included managers (KKR Investment Management LLC and KKR Credit Advisors (US) LLC), filed a Form 13F HOLDINGS REPORT for the quarter ended 30 Jun 2026 (filed 14 Aug 2026, accession 0001399770-26-000008), reporting 104 positions with a total reported value of $5,708,924,781. This is public credit, liquid strategies and similar securities managed for KKR's funds and clients, not KKR's own strategic balance-sheet stakes. Per the brief's exclusion of client-held positions, no line item from this filing appears in holdings, the same treatment this project's ameriprise.json and pnc.json apply to their own 13F filings. Note this filer is a wholly distinct EDGAR registrant from KKR & Co. Inc. (CIK 0001404912) itself, which files no 13F.
• How balance-sheet stakes were separated from fund positions. KKR reports three segments: Asset Management (fee and carry business, including 'Core Private Equity' AUM of $41 billion as of 31 Dec 2025, a fee-earning third-party fund strategy, excluded here as a fund/client position), Insurance (Global Atlantic, in which KKR acquired the remaining equity interests on 2 Jan 2024 and which is now a wholly owned consolidated subsidiary, excluded per the brief's wholly-owned-subsidiary rule, not a minority stake), and Strategic Holdings (dividend and realized-gain income on companies KKR names directly in its MD&A, used here as the signal for a genuine balance-sheet stake). Strategic Holdings segment positions are held through 'consolidated core private equity vehicles': legally the same fund vehicles used for third-party AUM, consolidated onto KKR's GAAP balance sheet because KKR controls the GP, with third-party LP capital stripped out as noncontrolling interests. The segment's reported 'Dividends, net' and 'Net Realized Investment Income' approximate KKR's own retained economic interest, but neither the 10-K nor the 10-Q discloses an ownership percentage or fair value for any individual named investee, so every Strategic Holdings holdings row below carries shares: null and value_usd: null.
• Combined balance, not split by investee. The Q2 2026 10-Q's VIE note discloses a combined 'Asset Management and Strategic Holdings Investments' balance of $12,323,070 thousand (maximum exposure to loss from VIEs in which KKR is not the primary beneficiary) and, separately, a combined balance-sheet 'Investments' line of $127,562,546 thousand at 30 Jun 2026 covering the Asset Management and Strategic Holdings segments together. Neither figure is split between the two segments, let alone between individual investees, so per the rule against assigning a combined balance to one investee, none of it is attributed to any single holdings row; both figures are reported here rather than converted into invented per-company values.
• Marshall Wace LLP is the one holdings row with a genuinely disclosed, precise ownership percentage: a 39.6% interest as of 31 Dec 2025 (FY2025 10-K), explicitly described as a minority stake in a third-party hedge fund manager, distinct from the Strategic Holdings segment and from Core Private Equity AUM. No dollar value for the stake is disclosed.
• Two Strategic Holdings exits found but excluded from holdings as no longer current: FiberCop S.p.A. (realized gain from its sale during FY2024, per the FY2025 10-K) and an unnamed telecommunications-sector investee plus Refresco Group B.V. (manufacturing sector), both associated with FY2025 realized investment income, which the 10-K's wording ties to a sale rather than an ongoing dividend-paying position. Neither is named again in the Q2 2026 10-Q.
• No KKR Holdings partnership-unit overhang, unlike the Blackstone chunk-9 defect. KKR completed the acquisition of KKR Holdings L.P. and its 258.3 million KKR Group Partnership Units on 31 May 2022, in exchange for 266.8 million shares of common stock issued to KKR Holdings' limited partners; the related tax receivable agreement was terminated 30 May 2022 (a residual $335.1 million payable for pre-termination exchanges remains on the balance sheet at 30 Jun 2026, unrelated to any current unit count). All four founder/executive register rows (Roberts, Kravis, Nuttall, Bae) are common stock beneficial ownership from the Feb 2026 special-meeting proxy, the same instrument as company.shares_outstanding, not partnership units.
• KKR does have a control structure separate from economic ownership, and it is not a second common share class. KKR has a single class of common stock, but KKR Management LLP holds the sole outstanding share of Series I preferred stock (owned by KKR's senior employees, including Co-Founders Kravis and Roberts), which under the existing charter carries significant voting control; common stock does not yet vote on a one-share-one-vote basis. On the 'Sunset Date' (no later than 31 Dec 2026, or six months after both Co-Founders' death or permanent disability if earlier), KKR will cancel the Series I preferred stock, move to one vote per common share, and KKR will acquire control of the carry pool (Associates Holdings). Separately, KKR & Co. Inc. also has 51,750,000 shares of 6.25% Series D Mandatory Convertible Preferred Stock outstanding (CUSIP 48251W500), an economic instrument distinct from common stock. Several 13F filers checked for this register (BlackRock, State Street, FMR, Morgan Stanley, Bank of America, and all three Capital Group entities) also hold Series D shares; those Series D holdings were identified and excluded from every register row above, which count CUSIP 48251W104 (common stock) only, per the one-instrument-one-basis rule.
• Vanguard case: parent CIK 0000102909 filed Form 13F-NT (notice, no holdings) for Q2 2026 (filed 13 Aug 2026), so the successor case applies: two successor entities summed to 54,746,353 shares, as detailed in that row's method_note.
• Capital Group case: all three family entities hold KKR (World Investors, International Investors, Research Global Investors), summed to 58,873,502 shares, the largest holder in this register. Checking only Capital World Investors, as the smallest of the three at 7,775,190 shares, would have understated the family by more than 51 million shares, the exact failure mode the brief warns against.
• T. Rowe Price case: both CIKs (Associates and the separate Investment Management registrant) hold KKR, and both report info-table values in thousands of dollars rather than whole dollars; both were rescaled by 1000x as detailed in that row's method_note, cross-checked against BlackRock's implied per-share price for the same CUSIP and date.
• Proxy cross-check: the Feb 2026 special-meeting proxy's own 'stale' 5% Stockholders table (based on prior Schedule 13G/A filings, as of the proxy's Record Date) shows The Vanguard Group Inc. at 56,245,699 shares (6.31%) and BlackRock, Inc. at 44,890,451 shares (5.04%). These are reasonably close to, and not materially inconsistent with, the fresher Q2 2026 13F-HR figures used in the register above (Vanguard 54,746,353 shares/6.10%; BlackRock 45,188,181 shares/5.03%).
• Self-gate, computed the way the chart computes it: 19 register rows (14 institutional 13F rows plus 4 individually named insiders plus 1 aggregate officers/directors group). Members rolling into the aggregate (Roberts, Kravis, Nuttall, Bae) count at full value; the aggregate group counts at its residual of 206,873,438 minus their combined 204,688,967 = 2,184,471. Total: 291,514,553 (institutional) + 204,688,967 (named insiders) + 2,184,471 (group residual) = 498,387,991 shares, or 55.52% of 897,635,601 shares outstanding. This is just above the 25-45% expected band and marginally above the 55% outer bound. The concentration is named and sourced rather than an artifact: KKR's two living Co-Founders alone hold a combined 18.39% (Roberts 9.34% plus Kravis 9.04%), on top of an unusually concentrated institutional base where Capital Group (6.56%), Vanguard (6.10%) and BlackRock (5.03%) together hold 17.69%. No double-counted holder or mixed instrument was found on review: all 13F rows are common-stock-only (Series D preferred and other KKR-managed listed vehicles were explicitly excluded from every row), and the four insider rows are common stock beneficial ownership from the same 2022 post-KKR-Holdings-retirement basis as shares_outstanding.
• Market cap ($97.69 billion) and share price ($108.83) are from a Yahoo Finance quote as of the 17 Aug 2026 close. Cross-check: 897,635,601 shares x $108.83 implies approximately $97.69 billion, matching.
