Private company
Who owns Advanced Atomization Technologies, LLC
One company in the researched set discloses a stake in Advanced Atomization Technologies, LLC, none of it sized by anyone who discloses it. Advanced Atomization Technologies, LLC is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Parker-Hannifin Corporation. Ownership split (50/50 with GE Aviation) is from the November 14, 2012 joint venture formation announcement, not reconfirmed with a percentage in any current Parker SEC filing. Parker's Q3 FY2026 10-Q (period ended 31 March 2026) discloses that Aerospace Systems segment assets include 'an investment in a joint venture in which ownership is 50 percent or less and in which the Company does not have operating control' carried at 225 million dollars as of 31 March 2026 and 226 million dollars as of 30 June 2025, but the filing does not name the joint venture. Advanced Atomization Technologies is the only Aerospace Systems joint venture named anywhere in Parker's public filings (via an executive's job history in the FY2025 10-K proxy-adjacent bio) and its LinkedIn page shows activity into 2026, so this carrying value most likely corresponds to Parker's AAT stake, but that identification is an inference by this research, not a filing statement. The carrying value is therefore recorded in notes, not attached to this holding as value_usd. sourcesource 2source 3
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Advanced Atomization Technologies, LLC where a holder stated one, and are missing where no holder did.
