A 10-K is an annual report filed by public companies with the SEC within 60-90 days after fiscal year-end. It contains audited financial statements (income statement, balance sheet, cash flow statement), detailed management discussion (MD&A), risk factors, and business overview.
Formula
10-K Components:
- Audited financial statements (annual)
- 5-year selected financial data
- Management's discussion and analysis (MD&A)
- Risk factors
- Executive compensation details
- Business overview and strategy
Example
Apple's 10-K filed in late October 2024 covers Apple's fiscal year ending September 2024. It includes 50+ pages of financials, discussion of iPhone sales, services revenue growth, supply chain risks, executive compensation ($50M+), and auditor sign-off on accuracy.
How to Interpret It
- Financial statements: Start here for audited revenue, earnings, cash flow, and balance sheet data.
- MD&A section: Management's perspective on performance, strategy, and outlook. Most readable part.
- Risk section: Honest disclosures of what could go wrong (competition, supply chain, macro risks).
- Executive compensation: See how much the CEO and top executives earn; often controversial.
- Auditor's report: Whether the auditor found any red flags or needed to qualify the opinion.
- Year-over-year comparisons: 10-Ks show prior-year data, enabling trend analysis.
Limitations
- 10-Ks are backward-looking; they report results 2-3 months after year-end, so they're already old by the time you read them.
- Management writes the MD&A, so it's biased toward positive framing (though required to disclose risks).
- 50+ pages is a lot to read; most investors skim or skip to tables and charts.
- Auditors rarely truly catch fraud; they test samples and rely on management representations.
