Microchip Technology Incorporated

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 1,153 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

• Fiscal year and filing periods used. Microchip's fiscal year ends in late March (FY2026 ended 31 Mar 2026). The latest 10-K on file as of 18 Aug 2026 is for FY2026 (period ended 31 Mar 2026, filed 21 May 2026, accession 0000827054-26-000016). The latest 10-Q is for the first quarter of FY2027 (period ended 30 Jun 2026, filed 6 Aug 2026, accession 0000827054-26-000038). The latest DEF 14A is the 2026 proxy statement (filed 6 Jul 2026, accession 0000827054-26-000026, beneficial ownership table dated 22 Jun 2026, shares outstanding 543,008,370 on that record date). These three filings, all dated within the current fiscal year, are the basis for this file; no filing from the prior (FY2025) cycle was used for any current figure.
• Holdings side, empty by design, a sourced finding. Both the FY2026 10-K and the Q1 FY2027 10-Q were searched for 'non-marketable', 'equity method', 'strategic investment', 'privately held', 'joint venture', 'unconsolidated', 'equity securities without readily determinable', 'equity investment', 'unrealized gain/loss', 'cost method', 'affiliate', 'minority interest', 'noncontrolling interest' and 'consolidated variable interest'. Every one of these returned zero hits in both filings except 'affiliate', which appears twice in the 10-Q only in export-control risk-factor language about Chinese state-owned entities, unrelated to any equity stake. The 10-K's 'Principles of Consolidation' policy note states the consolidated financial statements include only 'Microchip and its majority-owned and controlled subsidiaries', with no equity-method or minority-interest policy language at all, unlike a company that discloses an equity-method policy with a zero balance. The balance sheet carries a single 'Other assets' line ($358.1 million at 30 Jun 2026, $364.4 million at 31 Mar 2026) with no supporting note breaking it into components or naming any investee; cash flow statements show a similarly unbroken 'Investments in other assets' line. No note in either filing is titled anything resembling investments, equity securities or affiliates. This is the same shape of finding as Broadcom's case in this project: searched in full, nothing found, reported as a finding rather than left as a silent gap.
• Share basis and convertible instruments kept out of the denominator. company.shares_outstanding (543,008,691) is the Q1 FY2027 10-Q cover page figure, 'as of July 28, 2026'. Microchip has three tranches of convertible debt outstanding at 30 Jun 2026: the 2017 Senior Convertible Debt ($37.9 million carrying value, holders had a conversion right open 1 Jul to 30 Sep 2026 because the stock price condition was met), the 2024 Senior Convertible Debt ($1,239.3 million, not convertible as of 30 Jun 2026) and the 2026 Senior Convertible Debt ($885.0 million, not convertible as of 30 Jun 2026). None of these were added to shares_outstanding; the 10-Q explicitly treats their as-converted shares only as a dilutive adjustment in diluted EPS, not as issued and outstanding common stock. Microchip also has 7.50% Series A Mandatory Convertible Preferred Stock (about 1.5 million preferred shares issued March 2025, raising $1.45 billion net, each convertible into 16.0060 common shares at the holder's election, or about 24 million common shares if fully converted) which is likewise excluded from the common share count; it is a separate class with its own CUSIP (595017302, traded as depositary shares) and is not included in shares_outstanding or in any register row's share count. No stock split occurred in the periods reviewed.
• Preferred depositary shares (CUSIP 595017302) appear throughout the 13F register data as a distinct instrument from common stock (CUSIP 595017104) and are excluded from every register row above per one-instrument-one-basis: BlackRock held 2,311,148 of them ($177.3 million), State Street 459,769 ($35.3 million), FMR 334,467 ($25.7 million) and Capital International Investors (Capital Group family, CIK 0001562230) held 3,120,736 of them ($239.4 million) but zero common shares. Capital Group is therefore not included as a register row: its only MCHP exposure found is in the preferred depositary shares, a different instrument from the common-share denominator used throughout this register, and JPMorgan separately carries a small PREF CONV derivative line on the same CUSIP, also excluded. The other two Capital Group entities in the mandated check, Capital World Investors (CIK 0001422849) and Capital Research Global Investors (CIK 0001422848), were searched by name fragment across their full Q2 2026 info tables (637 and 426 rows respectively) and neither holds any Microchip security.
• Vanguard case: parent CIK 0000102909 filed Form 13F-NT (notice, no holdings) for the quarter ended 30 Jun 2026, confirmed directly against its EDGAR submissions feed. Per the brief's rule, the successors are summed rather than one row substituted: Vanguard Capital Management LLC and Vanguard Portfolio Management LLC, both common stock only, totaling 68,441,519 shares.
• BlackRock's 13F filer entity changed CIK during 2026: the historical CIK 0001364742 ('BlackRock, Inc.') last filed a 13F-HR in August 2024 and has filed none since; the current filer for Q2 2026 is CIK 0002012383, also named 'BlackRock, Inc.'. Confirmed via its EDGAR submissions feed before using it.
• Berkshire Hathaway was checked (89 info table rows in its Q2 2026 13F, filed 14 Aug 2026) and holds no Microchip position of any kind. Wellington Management's US filing entity, Wellington Management Co LLP (CIK 0001633863), filed a 13F-NT (no holdings) for Q2 2026; its holdings, if any, are reported by a different Wellington entity that was not identified within the time budget, so no Wellington row is included (see unknowns) rather than guessing which affiliate holds the position.
• Self-gate, computed with the chart's own arithmetic: 11 register rows (9 institutional 13F rows plus 2 proxy insider rows), Sanghi counted at full value (9,452,437) and the 11-person officers/directors group reduced to its residual of 9,718,089 minus 9,452,437 = 265,652 because Sanghi's row rolls up into it, sum to 215,194,526 shares against 543,008,691 shares outstanding, or 39.63 percent, within the expected 25 to 45 percent range.
• Market cap ($41.37 billion) and share price ($76.19) are from stockanalysis.com as of 18 Aug 2026 intraday (12:26pm EDT); stockanalysis.com reported the stock down about 5.1% on the day. Cross-check: the T. Rowe Price and BlackRock 13F figures both imply $91.20/share on 30 Jun 2026, consistent with a meaningful decline in the stock between then and 18 Aug 2026 rather than a data error.
• COORDINATOR EDGE BACKFILL, 19 Aug 2026: Cincinnati Financial Corporation was added to this register at 1,913,350 shares (0.3524%), verified by re-summing its five affiliated 13F registrants first-hand rather than copying the figure from cincinnati-financial.json. The charted register total moves from 215,194,526 (39.63%) to 217,107,876 (39.98%). It was found by investigating a SIZED crosscheck BACKFILL line, which this project treats as a real miss rather than noise: the chunk prompt records two earlier sized lines, berkshire to delta-air-lines and nvidia to coherent, that both turned out to be genuine missing holders. Twenty-six further Cincinnati Financial backfill lines were investigated at the same time and deliberately NOT actioned, because those stakes sit far below the target's own register threshold; this one does not.
