8-K

An 8-K is a mandatory report filed with the U.S. Securities and Exchange Commission (SEC) by a publicly traded company to announce major, unscheduled events that are important to shareholders and the financial markets. Think of it as the official “breaking news” alert for a company. Unlike the scheduled quarterly (10-Q) and annual (10-K) reports that provide a comprehensive look back, the 8-K is filed in near real-time—typically within four business days of a material event. This makes it an incredibly powerful tool for investors. For practitioners of value investing, an 8-K is a goldmine. It provides a raw, unfiltered look at a company’s evolving story, long before the narrative is polished into a glossy annual report. It's where you find the clues—both good and bad—that can signal a significant change in a company's intrinsic value, often before the rest of the market has had time to fully digest the news.

Why Should a Value Investor Care?

While the market often reacts frantically to the headlines of an 8-K, a savvy value investor knows the real treasure is buried in the details. These filings are not press releases; they are legal documents that must present the facts. This is your chance to be a detective and get ahead of the crowd. An 8-K can be the first sign of trouble, such as a major customer loss or the departure of a key executive. This might scare off momentum traders, but for a value investor, it could be the start of a market overreaction that creates a buying opportunity. Conversely, an 8-K might detail a strategic acquisition or a new patent that the market undervalues or misunderstands. By reading the primary document, you can form your own judgment about an event's impact on the company's long-term earning power, rather than relying on the simplified (and often sensationalized) interpretations from financial media. In short, 8-Ks help you answer a critical question: Is the company better or worse off today than it was last week?

What's Inside an 8-K?

The SEC outlines specific events that trigger an 8-K filing. While the full list is long, some of the most crucial ones for an investor to watch for include:

Key Triggers for an 8-K Filing

A Treasure Trove of Clues

Reading an 8-K is a skill. It's not just about knowing an event happened, but about understanding its implications.

How to Read an 8-K Like a Pro

Look Beyond the Headline

The filing will have a clear title, like “Item 5.02 Departure of Directors or Certain Officers.” Don't stop there. Read the full description. A CEO's departure could be a planned, orderly retirement announced a year in advance, or it could be an abrupt “resignation to pursue other opportunities” effective immediately. The former is business as usual; the latter demands deep skepticism and further investigation.

Read the Exhibits

This is where the real magic happens. The body of the 8-K provides a summary, but the exhibits contain the source documents. For example:

Comparing the dry, legal language of the agreement with the optimistic spin of the press release is a classic value investing technique for uncovering the truth.

Connect the Dots

An 8-K should never be read in a vacuum. How does this new information fit with what the company said in its last 10-K or shareholder letter? If a company known for its fiscal discipline suddenly takes on a mountain of high-interest debt, you need to ask why. Also, cross-reference the 8-K with other filings. For example, if a CEO suddenly resigns (8-K), are other insiders also selling their shares (check Form 4 filings)? This paints a much more complete picture than any single document can.
