Teledyne Technologies 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 832 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: The FY2025 10-K (filed 20 Feb 2026, period ended 28 Dec 2025) and the Q2 2026 10-Q (filed 24 Jul 2026, period ended 28 Jun 2026, the freshest filing on record) were both searched via scripts/filing.py for 'equity method', 'joint venture', 'unconsolidated', 'non-marketable', 'variable interest entity', 'noncontrolling interest', 'redeemable noncontrolling', 'minority interest' and 'equity securities'. Neither filing discloses any equity-method investee, unconsolidated joint venture or non-marketable equity security. The only noncontrolling-interest activity disclosed is the FY2025 buyout of the redeemable NCI in NL Acoustics for $27.2 million (Q3 2025), which extinguished that position entirely; NL Acoustics is not a holding as of the FY2025/Q2-2026 filings because Teledyne now owns 100% of it.
• Exhibit 21 to the FY2025 10-K (subsidiaries list) is a plain name/jurisdiction list with NO ownership-percentage column for any entity, majority or minority; this is the Labcorp/Darden shape, not the Quest/PPG shape. However, two entries carry an explicit parenthetical flag the rest of the list does not: 'Ocean Aero, Inc. (minority interest) Delaware' and 'SCI CEDIP (minority interest) France'. Both were investigated outside the 10-K/10-Q (SEC full text search plus web search for the underlying transactions) and are carried as holdings above, each sized by the best available disclosed figure (Teledyne's own 2015 press release for Ocean Aero at ~37%; FLIR's pre-acquisition 2008 10-K for Cedip at 99.9%), with confidence 'estimated' because Teledyne itself has never disclosed a current percentage for either.
• Register self-gate, computed from this file on disk exactly as the chart computes it: 12 rows, no rolls_up_into relationships (the insider group has no member rows beneath it, so it counts at full value). Total shares = 26,100,424. shares_outstanding = 46,355,673 (Q2 2026 10-Q cover page, 'There were 46,355,673 shares of common stock ... outstanding as of July 15, 2026'). 26,100,424 / 46,355,673 = 56.30%, slightly above the 25-55% band the brief describes as typical. This is treated as a genuine result, not an error: Teledyne has an unusually small float (~46.4 million shares) at a high share price (~$656-680 in Aug 2026), which the brief itself flags as the reason a small-float, heavily institutionally owned company can land above 55%. Every row was cross-checked for a consistent implied price (~$667/share on the Q2 2026 13F rows) and no unit or denominator error was found. Corroborated first-hand by the coordinator against this project's own 13F-derived register (data/registers/TDY.json, period 31 Mar 2026, separate pipeline): its top TWELVE holders sum to 56.89% of the same denominator against the 56.30% recorded here from twelve rows, and total institutional ownership is 35,519,382 shares, 76.62%. Two independent derivations agreeing to within 0.6 percentage points on the same row count confirms the level is real, and it is what a 46.4 million share float with heavy index ownership produces. The $667.03 implied-price cluster across all twelve rows separately rules out a units error.
• Entity lists for Vanguard and T. Rowe Price were drawn from this project's own data/registers/TDY.json snapshot (period 31 Mar 2026) as a WHO-holds guide only; every share and value figure in this file was pulled fresh from each entity's own Q2 2026 (period 30 Jun 2026) 13F-HR information table, not from that snapshot, per the brief's instruction.
• Vanguard's parent, The Vanguard Group, Inc. (CIK 0000102909), was not found filing any 13F for the Q2 2026 period under that CIK; the eight successor entities checked (Capital Management LLC, Portfolio Management LLC, Fiduciary Trust Co, Global Advisers LLC, Asset Management Ltd, Investments Australia Ltd, Personalized Indexing Management LLC, National Trust Co) each filed their own fresh 13F-HR for the period, so per the PNC precedent in the brief they were summed as the family total rather than substituted.
• Capital Group was checked and holds nothing: Capital World Investors (CIK 0001422849), Capital International Investors (CIK 0001562230) and Capital Research Global Investors (CIK 0001422848) were each queried against their own Q2 2026 13F-HR information tables for CUSIP 879360105 / issuer name fragment TELEDYNE, and none returned a matching row. No register row is carried for Capital Group as a result.
• T. Rowe Price Investment Management, Inc. (CIK 0001897612) does hold TDY (159,145 shares, Q2 2026), unlike the Capital Group case; it is summed with T. Rowe Price Associates, Inc. into the single family row above rather than listed separately, per the brief's guidance to sweep the T. Rowe family across both registrants.
• FMR LLC (Fidelity's US-domestic registrant, CIK 0000315066, distinct from FIL Ltd/Fidelity International) was checked and holds only 62,266 shares (0.13%) as of Q2 2026, too small to place in the top 8-12 alongside FIL Ltd's much larger 1,834,853-share position; it is not carried as a register row.
• The 2026 DEF 14A's own 'Five Percent Owners of Common Stock' table (as of 17 Feb 2026, sourced to Schedule 13G/A amendments filed Jan 2026) lists Vanguard at 5,977,777 sh / 12.9%, BlackRock at 4,126,878 sh / 8.9% and T. Rowe Price Associates at 3,126,015 sh / 6.8%. Per the brief, these stale 13G-derived proxy figures are superseded in this file by the fresher Q2 2026 13F-HR figures fetched directly; the two sets are close but not identical (e.g. Vanguard's fresh family total of 5,886,098 is below the stale 13G figure of 5,977,777, and BlackRock's fresh 4,125,237 is essentially flat versus the stale 4,126,878), consistent with normal quarter-to-quarter portfolio movement rather than a units or entity error.
• Teledyne has agreed to acquire Varex Imaging in an all-cash transaction valued at approximately $1.1 billion (per public reporting as of Aug 2026); as a pending wholly owned acquisition this is not a holding and is noted here only for context, not sized or sourced to a filing.
