Insights

TL;DR: Combined holdings represent a meaningful >5% stake, with shared voting power across related entities.

The Schedule 13G/A shows clear, quantifiable positions: Madrone Opportunity Fund holds 16,762,216 shares (5.6%) and Shimoda holds 3,500,000 shares (1.2%), producing an aggregate beneficial ownership for Gregory Penner of 20,262,216 shares (6.8%). Reported authority is shared voting and shared dispositive power, which signals coordinated control over disposition and voting of these shares even as the filing explicitly disclaims group status. The percent basis is disclosed as 300,084,685 shares outstanding, giving clarity to the stake magnitude.

TL;DR: Managers and entities report overlapping authority; formal disclaimer of a "group" contrasts with shared powers disclosed.

The filing documents that Madrone GP, as general partner of Madrone Opportunity Fund, and managers (Penner, McJunkin, Patterson) share voting and investment authority over Madrone's 16,762,216-share position. Shimoda's 3,500,000-share position is managed in part by Penner. While the Reporting Persons "expressly disclaim" group status, the combination of shared voting and shared dispositive power is governance-relevant and amounts to a substantive disclosure for investors assessing potential influence on issuer decisions.
