Who owns South San Francisco JVs (multiple lab joint ventures)
One company in the researched set discloses a stake in South San Francisco JVs (multiple lab joint ventures), worth $286m between them. South San Francisco JVs (multiple lab joint ventures) 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.
What this is
Not a single company but Healthpeak's own aggregated label for several unconsolidated joint ventures that hold seven laboratory buildings in South San Francisco, California, created on 1 August 2022 when a 30 percent interest in those buildings was sold to an unnamed sovereign wealth fund for 126 million dollars, and described nowhere outside Healthpeak's SEC 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.
- Healthpeak Properties, Inc., as of 30 Jun 2026. Healthpeak's 30 Jun 2026 10-Q, Note 7 ('Investments in Unconsolidated Joint Ventures'), discloses a table with a per-entity carrying amount AND ownership percentage for each equity-method JV, unlike a combined undisaggregated balance. 'South San Francisco JVs' aggregates multiple unconsolidated lab JVs in South San Francisco, California, 7 properties, in which Healthpeak holds a 70% ownership percentage in EACH JV; footnote (3) states these are aggregated in the table 'due to similarity of the investments and operations,' so the company's own disclosure, not this file's judgment, is what combines them. Carrying amount at 30 Jun 2026: $285,611 thousand = $285,611,000 (vs $285,387 thousand at 31 Dec 2025). This is a carrying (book) value under the equity method, not a market value; value_price_per_share is null because there is no share price for a private JV interest. 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 South San Francisco JVs (multiple lab joint ventures) where a holder stated one, and are missing where no holder did.
