Reading SEC Filings

The 10-K is the most comprehensive filing a company produces. Filed annually within 60 days of fiscal year end (for large accelerated filers), it contains a complete picture of the company's business, risks, financials, and operations. The document is structured in four parts with specific items in each.

Part I includes the business description (Item 1), risk factors (Item 1A), and properties (Item 2). The business description explains what the company does, its competitive landscape, and its strategy. Risk factors is often the most underread yet valuable section—it lists everything management believes could go wrong, from competitive threats to regulatory risks to macroeconomic vulnerabilities.

Part II contains the financial statements and MD&A (Management Discussion & Analysis). The MD&A is where management explains the financial results in their own words—why revenue grew or shrank, what drove margin changes, and how they view the business going forward. This section bridges the gap between raw numbers and business context.

The 10-Q is a slimmed-down version of the 10-K, filed quarterly (except Q4, which is covered by the 10-K). It contains updated financial statements, an MD&A section, and notes—but lacks the full business description and some detailed disclosures found only in the annual filing.

When reading a 10-Q, focus on three areas: the financial statements themselves (comparing to the same quarter last year), the MD&A (for management's explanation of trends), and the notes to the financial statements (for any new accounting changes, litigation updates, or debt modifications). The notes often contain critical information that doesn't appear in the press release.

Develop a routine: within a week of each quarterly earnings release, pull up the 10-Q and scan the MD&A and notes. This 15-20 minute exercise will surface information that most investors miss because they rely solely on the earnings press release and conference call. Pay special attention to changes in accounting estimates, new contingent liabilities, and related-party transactions.

Form 8-K is the "current report" that companies must file within four business days of a material event. These events include: CEO or CFO departures, acquisitions or divestitures, material agreements, bankruptcy, changes in auditors, and other significant developments. 8-Ks can be filed at any time and often move stock prices.

Setting up email alerts for 8-K filings from your portfolio companies is one of the most valuable things an investor can do. A Friday afternoon 8-K announcing that the CFO resigned "to pursue other opportunities" is the kind of red flag you want to know about immediately, not days later when it appears in news articles.

Common 8-K items to watch include: Item 2.02 (results of operations—often filed with the earnings press release), Item 5.02 (departure/appointment of officers), Item 1.01 (entry into a material agreement), and Item 8.01 (other events the company deems important). The attachments (exhibits) to 8-Ks often contain the actual documents—contracts, agreements, and letters—that provide far more detail than the filing itself.

The proxy statement, filed before the annual shareholder meeting, contains invaluable information about corporate governance, executive compensation, and insider ownership. It's required reading for understanding how a company is managed and whether management's interests are aligned with shareholders.

The executive compensation section reveals how much the CEO and other executives earn and, critically, how they earn it. Look at the mix of base salary, bonuses, stock awards, and options. Well-designed compensation ties the majority of pay to long-term performance metrics like earnings growth, return on capital, or total shareholder return. Red flags include guaranteed bonuses, low performance thresholds, or metrics that can be easily manipulated.

The ownership table shows how much stock executives and directors own. High insider ownership (executives with significant personal wealth tied to the stock) generally aligns interests with shareholders. Conversely, executives who own minimal stock relative to their compensation have less skin in the game. Also check the insider trading section for recent buying and selling by executives.

Forms 3, 4, and 5 report stock transactions by company insiders—officers, directors, and anyone owning more than 10% of the company's shares. Form 4 is the most important, filed within two business days of a transaction. When a CEO buys $2 million of stock on the open market, that's a strong vote of confidence.

Distinguish between informative and non-informative transactions. Open market purchases by executives are the most bullish signal—they're spending their own money. Selling is less informative because executives sell for many non-bearish reasons (diversification, tax planning, buying a house). However, cluster selling—multiple insiders selling around the same time—can be a warning sign.

Also watch for 10b5-1 plans, which are pre-scheduled selling programs. These are set up months in advance and execute automatically, so they're less indicative of insider sentiment than spontaneous transactions. The footnotes in Form 4 filings usually indicate whether the sale was part of a 10b5-1 plan.

The footnotes to the financial statements—found in both the 10-K and 10-Q—are where the real details hide. Revenue recognition policies, debt terms and covenants, pension obligations, contingent liabilities, and related-party transactions are all disclosed in the footnotes. Accounting scandals often leave early warning signs in the footnotes that careful readers can detect.

Key footnotes to always read: Revenue recognition explains when and how the company counts revenue. Changes in this policy can significantly affect reported numbers. Debt footnotes detail interest rates, maturity schedules, and covenants—restrictions the company must comply with to avoid default. Commitments and contingencies reveal lawsuits, regulatory investigations, and contractual obligations.

Compare footnotes quarter to quarter. New risk factors, changes in accounting policies, and increased litigation reserves often appear first in the footnotes before manifesting in the headline financial numbers. This is why professional analysts and short sellers read footnotes religiously—they're looking for early warning signs that casual investors miss.
