What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Clearline Capital 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.

Declared options (1)
Besides stocks, Clearline Capital declared 1 put (they gain if the stock falls) with a notional of $126M. 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.

Stakes above 5% (13D/13G)
Companies where this filer reported holding 5% or more of the shares. It is the figure from its latest filing on each one; history since December 2024.
How we classify it
Investment firm, per its Form ADV of May 8, 2026 (high confidence).
The data, as reported: CLEARLINE CAPITAL LP (CRD 166699): 7.B private funds: 1 hedge (gross assets $1.4 bn); 5.D assets by client type: pooled vehicles 100% (of $1.4 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.
