Joint venture with Ariston Group ("Ariston JV", manufactures and distributes water heaters through Lennox Stores and the direct-to-dealer network) 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 Lennox and Ariston Group Announce Joint Venture to Launch Water Heaters in North America (PR Newswire, May 2025) and Lennox Launches Water Heater Joint Venture With Ariston Group (Dallas Innovates). 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.
- Lennox International Inc.. FY2025 10-K, Item 1 Business: 'Ariston JV. We own a 49.9% interest in a joint venture with Ariston Group that will manufacture and distribute water heaters through Lennox Stores and our direct-to-dealer network. Ariston is reporting in our Home Comfort Solutions segment.' Not named in Exhibit 21. Covered by the same undisclosed-split combined equity-method balance ($59.7 million at 31 Dec 2025) as the other three ventures in Note 11, so no share count or dollar value is assigned to this row specifically. source
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 Joint venture with Ariston Group ("Ariston JV", manufactures and distributes water heaters through Lennox Stores and the direct-to-dealer network) where a holder stated one, and are missing where no holder did.
