Insights

Securities Analyst

TL;DR: Maverick reports a passive 5.5% stake (6,647,830 shares) in Peabody with shared voting/dispositive power, filed on Schedule 13G.

The filing discloses a material but non-controlling position equal to 5.5% of outstanding common stock, aggregated across multiple Maverick funds and managed accounts. Because the disclosure is on Schedule 13G and contains a certification that the stake is not for control purposes, the position appears passive under the rules. Key takeaways for investors are the size of the stake relative to the 121.6 million share base and that voting/dispositive power is shared, not sole, which limits direct influence by the reporting persons.

Corporate Governance Expert

TL;DR: A 5.5% passive holding signals meaningful investor interest but no change in control; voting power is shared.

The report names the general partner and managing partner relationships (Maverick Capital Management as GP; Mr. Ainslie as manager), clarifying the reporting chain. The Schedule affirms the position was not acquired to influence control and includes joint filing and power-of-attorney exhibits. For governance, shared voting power suggests coordination among funds and accounts rather than direct unilateral action by a single entity.
