Intro to SEC Forms

Back to Basics, Part 1

Decoding the Alphabet Soup

Public companies in the United States are required to file a variety of reports with the Securities and Exchange Commission (SEC). These filings provide transparency into a company’s financial health, risks, operations, and major events.

If you’ve ever wondered what a 10-K, 10-Q, or 8-K actually means, this part of the series breaks it all down in plain English.

Form 10-K: The Annual Report That Means Business

The 10-K is the most comprehensive annual filing a company produces. It includes audited financial statements, risk factors, management’s discussion and analysis (MD&A), and a detailed overview of the business.

Key Distinction The 10-K is a legal document — not a glossy marketing brochure. Companies are required to disclose risks, weaknesses, and anything that could materially affect the business.

Filing Deadlines for Form 10-K

Filer Category Deadline After Fiscal Year End
Large Accelerated Filer (public float ≥ $700M) 60 calendar days
Accelerated Filer ($75M–$700M) 75 calendar days
Non-Accelerated Filer (public float < $75M) 90 calendar days

Form 8-K: Breaking News, SEC Style

The 8-K is a “current report” used to disclose major events that occur between quarterly or annual filings. It keeps investors informed about significant developments.

Common triggers for an 8-K include:

Updated Deadline Companies must file Form 8-K within four business days of the triggering event.

Form 10-Q: The Quarterly Check-In

The 10-Q is a quarterly update that provides a snapshot of the company’s performance. Unlike the 10-K, the financial statements in a 10-Q are typically unaudited.

Filing Deadlines for Form 10-Q

Filer Category Deadline After Quarter End
Large Accelerated Filer 40 calendar days
Accelerated Filer 40 calendar days
Non-Accelerated Filer 45 calendar days

At a Glance: Comparing the Three Forms

Putting It All Together

These three forms — the 10-K, 10-Q, and 8-K — form the backbone of corporate disclosure. Understanding them gives you a powerful advantage when analyzing companies.
