Insights

Corporate Governance Expert

TL;DR: Officer and director disclosure filed; reporting person holds no equity, reducing direct insider ownership alignment.

The Form 3 confirms that Michael W. Sumruld is an officer (SVP, Finance) and a director-level reporting person for Oceaneering International, Inc. as of the event date of 09/02/2025. The filing shows no beneficial ownership of common stock at the time of the statement. From a governance perspective, initial disclosure compliance appears satisfied. The absence of share ownership means Mr. Sumruld has no direct equity stake disclosed here, which can be relevant when assessing insider alignment with shareholders, but the form does not provide further context on future equity awards or prior holdings.
