Insights

Financial Analyst

TL;DR: A coordinated investor group holds an ~8.9% stake, disclosing acquisition costs and potential additional shares from RSUs.

The filing shows the Coghill-affiliated group holds a meaningful minority position in AMPY based on 40,466,053 shares outstanding. Stoney Lonesome accounts for the bulk of the position with 3.5 million shares and disclosed aggregate purchase price of approximately $19.65 million, indicating an average acquisition price near recent market levels implied by the filing. The inclusion of 41,922 RSUs awarded to Mr. Coghill could incrementally increase his direct stake upon vesting and conversion. The Joint Filing Agreement clarifies coordinated reporting and shared voting/dispositive power among the reporting persons.

Corporate Governance Expert

TL;DR: Reporting shows shared control and a board member with equity incentives, relevant for governance and shareholder alignment.

The filing identifies Clint D. Coghill as a director of the issuer and as President/sole shareholder of CDC Financial, which may be deemed to beneficially own the combined holdings. The disclosure of shared voting and dispositive power over Stoney Lonesome and Drake Helix holdings signals coordinated influence. The RSU grant of 41,922 units that vest after one year aligns director incentives with shareholder outcomes, subject to continued board service. The Joint Filing Agreement formalizes joint approach to Schedule 13D reporting.
