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

How we classify it
Investment firm, per its Form ADV of Mar 9, 2026 (high confidence).
The data, as reported: TELEMARK ASSET MANAGEMENT, LLC (CRD 156770): 7.B private funds: 1 hedge (gross assets $1.1 bn); 5.D assets by client type: pooled vehicles 100% (of $1.1 bn)
The type comes from a rule applied to that data. If it looks wrong, tell us.
Not counted as a concentrated manager: 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
