Jack Henry & Associates, 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 758 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 side: searched the most recent 10-K (fiscal year ended 30 Jun 2025, filed 25 Aug 2025) and the most recent 10-Q (period 31 Mar 2026, filed 7 May 2026, the newest filing available since the FY2026 10-K had not yet been filed as of 19 Aug 2026, the research date) for 'equity method', 'equity investment', 'non-marketable', 'joint venture', 'unconsolidated', 'privately held', 'investment in', 'cost method', 'strategic investment', 'minority interest', 'marketable securities', 'variable interest entity', 'affiliate', 'consolidated subsidiaries', 'noncontrolling interest', 'business combination'. None of these terms produced a hit describing any minority equity stake in another company; the only 'affiliate' hits were boilerplate (Section 16 aggregate-market-value language and a credit-agreement reference to Jack Henry's own guarantor affiliates). Exhibit 21.1 of the FY2025 10-K was also read directly: it is a bare 7-name list of Jack Henry's own wholly owned subsidiaries (Goldleaf Insurance LLC, JHA Payment Solutions Inc., Towne Services Inc., iPay Technologies LLC, Profitstars LLC, JHA Money Center Inc., Payrailz LLC), no ownership-percentage column, no joint-venture entities. The 10-Q's only acquisition disclosure (NOTE 10, Victor Technologies, Inc., an asset purchase completed 30 Sep 2025 for $42,390 thousand) resulted in a wholly owned, fully consolidated business, not a minority position. Conclusion: as a mid-cap bank-technology vendor, Jack Henry holds no equity-method, cost-method, joint-venture, or other minority equity stake in any other company as of the most recent available filings; holdings is legitimately empty, matching the pattern the brief predicted for a company of this type.
• Self-gate computed from this final file: 12 register rows, 32,571,996 total shares (no row rolls up into another; the officers/directors aggregate has no separately broken-out member rows, so it counts at its own full value per the chart's own arithmetic), against shares_outstanding 71,050,780 = 45.84% of the company. This sits just above the brief's roughly 25-45% typical band but well under its 55% hard-flag threshold. Checked for the usual causes and found none: no mixed instrument (every institutional row is CUSIP 426281101 common stock, none is an LP/partnership unit or a pre-split count), no mixed basis (all institutional rows are filed_13f from each holder's own Q2 2026 filing; the aggregate is clearly labeled proxy_statement), and no double counting (Vanguard is one family row summed from 8 successor 13F-HR filings behind a 13F-NT parent; Capital Group is one family roll-up from 6 checked entities, 2 of which actually hold; T. Rowe Price is Associates only, its sibling registrant checked and confirmed to hold nothing; every other institutional holder appears exactly once). The elevated reading reflects that Jack Henry's top 8 institutional rows alone already total roughly 44.8% of the company: a widely held mid-cap ($11.6bn market cap) with three big index managers (Vanguard, BlackRock, State Street, plus index-leaning sub-adviser Geode) and several sizeable active managers, most notably Kayne Anderson Rudnick Investment Management LLC at 7.34%, the single largest non-Vanguard holder. This is analogous to and consistent with Tyler Technologies (46.02%) in this same project, another vertical-market software company with heavy active-manager concentration and a comparatively small float; reported here rather than suppressed.
• Every large institutional row's dollar value divided by its share count lands within a tight ~$137.5-137.8 band across all Q2 2026 (30 Jun 2026) filers checked (Vanguard's 8 entities, Kayne Anderson Rudnick, BlackRock, State Street, Geode, Morgan Stanley, CIBC Bancorp USA, Invesco, Capital Group's 2 holding entities, and T. Rowe Price Associates after converting its thousands-denominated value), a strong independent cross-check that these are all the same instrument at the same date. APG Asset Management N.V. is the one exception, implying ~$120.5/share from its own reported value and share count; the figures were checked directly against the raw filing XML and are exactly as APG itself reported ($6,121,256 / 50,809 sh), so the row is kept with the discrepancy flagged rather than dropped or silently corrected. The same anomaly on this exact filer was also seen independently on Tyler Technologies in an earlier chunk of this project.
• The 2025 DEF 14A's own 5%-owner table (as of 16 Sep 2025) shows Vanguard at 8,648,967 sh (11.9%), BlackRock at 6,201,647 sh (8.5%), Kayne Anderson Rudnick at 4,739,277 sh (6.5%), Morgan Stanley at 4,249,072 sh (5.8%), and State Street at 3,976,907 sh (5.5%), all measured roughly 9-10 months before the Q2 2026 13F sweep used in this file. Per the brief's preference for fresh 13F data over any stale, earlier-dated proxy figure, the Q2 2026 13F sweep is used throughout; the proxy figures are recorded here and in each row's method_note as the reconciliation rather than being overwritten silently. Vanguard, Kayne Anderson Rudnick and (modestly) State Street moved UP between the two dates; BlackRock and Morgan Stanley moved DOWN, consistent with the brief's warning not to assume the correction runs one way.
• No 13D has ever been filed against Jack Henry stock (checked EDGAR's full SC 13 filing history for CIK 0000779152); every Schedule 13 filing on record is a 13G or 13G/A, the most recent dated 17 Oct 2024, consistent with an entirely passive institutional ownership base and no activist or strategic holder to add beyond the 13F-derived rows above.
• Current price used for market_cap_usd is a live end-of-day quote (Nasdaq API, $163.06 close, 19 Aug 2026, up 6.49% on the day, the session after the FY2026 Q4/full-year earnings release on 18 Aug 2026) multiplied by the 24 Apr 2026 cover-page share count from the most recent 10-Q. The two dates do not match exactly (about 4 months apart) because no single filing carries both a current price and a current share count, and no FY2026 10-K had been filed as of the research date to refresh the share count. This is disclosed rather than treated as precise.
• Jack Henry's fiscal year ends 30 Jun. As of 19 Aug 2026 (the research date) no FY2026 10-K (period 30 Jun 2026) had been filed; the company's FY2026 Q4/full-year earnings press release was furnished via 8-K on 18 Aug 2026 (Exhibit 99.1) but that exhibit carries only weighted-average diluted shares (70,872 thousand), not a dated cover-page shares-outstanding figure, so it was not used for shares_outstanding. The most recent filing carrying a dated shares-outstanding cover-page figure remains the 10-Q for the period ended 31 Mar 2026 (filed 7 May 2026): 71,050,780 shares as of 24 Apr 2026. This is the newest genuinely available cover-page figure, not a case of habitually reaching for a 10-Q over a fresher 10-K.
