SEC Schedule 13D / 13G Filing Made Simple

Stay Compliant When Crossing the 5% Ownership Threshold

What is Schedule 13D / 13G?

Schedules 13D and 13G are beneficial ownership reports filed with the SEC. Any individual or entity that acquires more than 5% of a registered class of a company's equity securities must file one of these schedules.

Schedule 13D: The long-form disclosure required for active investors who may influence or control the company.
Schedule 13G: A shorter, simplified disclosure available for passive investors and certain institutional investors.
Deadline: Must generally be filed within 10 days of crossing the 5% threshold, with amendments required for material ownership changes.
Why it matters: Provides transparency into large shareholders’ intentions and influence over a public company.

Why Schedule 13D / 13G Filing is Important

These filings complement Form 3, 4, and 5 filings under Section 16 by providing visibility into major ownership stakes, not just insider transactions.

Regulatory Requirement

Failure to file can result in SEC enforcement actions and penalties.

Investor Awareness

Signals to the market whether ownership changes are passive investments or potential activism.

Corporate Governance

Helps boards and management understand the shareholder landscape.

Ongoing Compliance

Amendments are required for significant changes, reducing the risk of SEC rejections.
