Insights

TL;DR: A well-known asset manager and related entities report a material passive stake of 7.0% in Kosmos Energy with sole voting and dispositive power.

The disclosure documents a sizeable institutional position of 33,411,046 shares and clarifies voting and disposition rights, which is material for ownership transparency. The filing also states the holdings are in the ordinary course of business, which reduces immediate governance-change concerns. For investors, the key takeaway is increased ownership concentration by a large adviser, which may affect liquidity and shareholder composition but contains no stated activism intent.

TL;DR: Reporting entities hold significant influence by share count and voting power, yet certify no intent to alter control.

The Schedule 13G shows clear allocation of sole voting power (30,486,885) and sole dispositive power (33,411,046), which matters for proxy voting and board-related outcomes. The filing's Item 10 certification explicitly asserts the shares are held in the ordinary course of business and not to influence control, and the joint-filing exhibit documents consent among the parties. This provides governance transparency without evidence of coordinated activist activity.
