Insights

Securities Analyst

TL;DR: A passive 5.04% stake was disclosed, crossing the 5% reporting threshold but filed as non-activist.

The Schedule 13G shows Energy Income Partners and four individuals collectively beneficially own 1,774,544 units of WLKP (5.04%). The split between sole and shared voting/dispositive power (403,727 sole; 1,370,817 shared) is explicit and indicates joint decision-making within the group. The filing’s certification states the holdings are passive and held in the ordinary course, reducing near-term expectations of control actions. Crossing 5% is material for disclosure and market transparency.

Corporate Governance Expert

TL;DR: Ownership structure shows meaningful minority stake but the filer affirms no intent to influence control.

The document identifies Energy Income Partners, LLC as the reporting entity and names four partners as associated persons. The report classifies the entity as an investment adviser and the individuals as holding-company affiliates. The greater portion of the position is under shared voting/dispositive power, suggesting coordinated group voting rather than unilateral control by one filer. The explicit certification of passive intent is an important governance signal to investors and the issuer.
