What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Zimmer Partners has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.
What changed this quarter
131 positions with a change (24 new, 26 added to, 37 trimmed, 44 sold); also, 11 entered through an IPO, 2 entered through a spin-off. 12 are listed here: those of 0.5 points of the portfolio or more (up to 12).

It started trading this quarter: it appears in a 13F for the first time. The filing does not say whether the manager already held it before the listing, so it is not counted as a purchase.

Declared options (9)
Besides stocks, Zimmer Partners declared 3 puts (they gain if the stock falls) and 6 calls (they gain if it rises) with a notional of $114M. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.

How we classify it
Investment firm, per its Form ADV of Apr 6, 2026 (high confidence).
The data, as reported: ZIMMER PARTNERS, LP (CRD 165684): 7.B private funds: 3 hedge, 1 inmobiliario (gross assets $4.3 bn); 5.D assets by client type: pooled vehicles 87%, insurers 13% (of $5.2 bn)
The type comes from a rule applied to that data. If it looks wrong, tell us.
Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
Similar managers by type and size
Same type of filer and a 13F portfolio value between a third and three times this one. It is not a comparison of what they hold.
