Westlake Chemical Partners LP (WLKP) reichte ein Formular 4 ein, das Insider-Aktivitäten der Direktorin Lisa A. Friel meldet. Am 06.08.2025 erhielt sie 5.005 Phantom-Einheiten, die jeweils wirtschaftlich einer Stammaktie entsprechen. Am 07.08.2025 üٱ sie 4.882 dieser Phantom-Einheiten in Stammaktien aus (Code M) und verkaufte 2.441 Einheiten zu je 21,96 $ (Code D). Nach den Transaktionen besitzt sie direkt 7.163 Stammaktien.

  • Ungefähres Bruttovolumen: ca. 107.000 US-Dollar (Ausübung) mit ca. 53.000 US-Dollar Erlös aus dem Verkauf.
  • Keine Phantom-Einheiten verbleiben; alle derivativen Positionen wurden umgewandelt oder abgewickelt.
  • Friel bleibt Direktorin des GP und hält somit eine Beteiligung im Einklang mit den Anteilseignern.
Positive
  • Director increased direct ownership to 7,163 common units, indicating continued equity alignment.
  • All derivative positions settled, simplifying the insider’s capital structure and reducing overhang.
Negative
  • Partial sale of 2,441 units at $21.96 may be viewed as limited insider profit-taking.
  • Transaction size is immaterial; unlikely to influence WLKP’s valuation or liquidity.

Insights

TL;DR: Small, routine option conversion; director keeps half of shares—mildly positive for alignment, but transaction size is immaterial to WLKP.

The grant of 5,005 phantom units and subsequent conversion suggests normal board compensation cadence. Retaining 2,441 newly issued units lifts Friel’s direct stake to 7,163, modestly increasing insider ownership. Disposal of the remaining half at $21.96 likely covers tax obligations rather than signaling bearish sentiment. Dollar amounts (<$0.2 m) are negligible relative to WLKP’s market cap, so market impact is limited. Overall, the filing is neutral from a valuation standpoint but provides a marginal positive governance signal through continued insider alignment.
