As of 30 June 2025, Astaris Capital Management LLP, its UK and Cayman affiliates, and control person Martin Beck report collective beneficial ownership of 2,207,299 common units, representing 6.5 % of KNOP’s outstanding units. The group holds shared voting and dispositive power over the entire stake and no sole authority. All units are owned by advisory clients of Astaris Capital Management LLP; no individual client exceeds the 5 % threshold.
The filing is made on a passive basis under Schedule 13G. Signatories certify the position was not acquired to influence control of the issuer. Martin Beck executed the certification on behalf of each reporting person on 5 Aug 2025.
Positive
Astaris Capital Management and affiliates disclose a 6.5 % stake (2.21 M units) in KNOP, expanding the partnership’s institutional ownership base.
Negative
None.
Insights
TL;DR Passive 13G shows Astaris owns 6.5 % of KNOP; modestly positive signal but limited control implications.
Materiality: A 6.5 % equity stake crosses the 5 % disclosure threshold, alerting investors to a meaningful institutional position. However, the filing is under Schedule 13G rather than 13D, indicating no activist intent. The shared, not sole, voting power and the disclaimer of beneficial ownership beyond pecuniary interest reduce governance impact. For KNOP, the appearance of a new (or increased) professional asset-manager holder can marginally broaden the investor base and potentially aid liquidity, yet does not directly alter fundamentals or strategy. Absent price-sensitive commentary, the disclosure is best viewed as informational.
