Who owns Tree Line Capital Partners
One company in the researched set discloses a stake in Tree Line Capital Partners, none of it sized by anyone who discloses it. Tree Line Capital Partners 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.

Tree Line Capital Partners is a private credit manager that lends directly to lower middle market companies in North America, founded in 2014 as a purpose built lower middle market lending platform and run from San Francisco with a New York office. It provides first lien term loans, unitranche term loans, revolvers, delayed draw facilities and equity co-investments to businesses with roughly 5 million to 30 million dollars of EBITDA in transaction sizes up to 150 million dollars, financing acquisitions, recapitalisations, refinancings and growth projects, and it usually acts as agent or sole lender rather than syndicating. The firm reports about 5.5 billion dollars of assets under management and 7.5 billion dollars of commitments issued across 506 companies financed. In January 2026 it closed its fourth flagship direct lending fund at 1.1 billion dollars, the largest raise in its history.
Source
Tree Line Capital Partners files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Tree Line Capital Partners, firm website, Tree Line Raises $1.1 Billion in Fourth Flagship Fund to Address Continued Demand in Lower Middle-Market (Business Wire) and Tree Line Capital (Stone Point Capital). The ownership figures below come from the holders' filings instead, and are sourced row by row.
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.
- Aflac Incorporated. Written as 40, not 0.40, per the brief's percentage-field convention. No dollar purchase price was disclosed; Aflac separately committed to allocate a portion of its annual investable cash flow to Tree Line over multiple years, on top of the equity stake, but no figure is given for that either. Not named in Aflac's Q2 2026 10-Q or FY2025 10-K. sourcesource 2
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 Tree Line Capital Partners where a holder stated one, and are missing where no holder did.
