financial-statement-review【数据与研究】Analyze and interpret financial statements to surface performance signals, quality concerns, and red flags. Use when an accountant says "review these financials", "analyze the income statement", "look at the balance sheet", "what does the cash flow statement tell us", "check the financial health", "ratio analysis", "are the earnings real", "working c…

references/industry-benchmarks.md - Ratio benchmarks by industry (SaaS, manufacturing, retail, professional services, healthcare). Read this in Step 4 when calculating ratios and when you need industry-specific thresholds to compare against.Based on "Financial Intelligence" by Karen Berman & Joe Knight and "The Interpretation of Financial Statements" by Benjamin Graham. Financial statements are not just numbers - they are a compressed story of business decisions. The goal of a review is not to recite figures but to answer three questions: Is this business profitable in a way that will last? Is it financially stable? Is the reported profit converting to real cash?
Graham's core principle: always read all three statements together. The income statement shows profit; the balance sheet shows what was built with it; the cash flow statement shows whether the profit is real.
Start with the income statement and look beyond the headline net income number.
Revenue: [amount] - Is it growing? At what rate? Is growth organic or acquisition-driven?
Gross Margin: [%] - Is it stable, expanding, or compressing? Why?
Operating Income (EBIT): [amount] - Is operating leverage positive (margins growing faster than revenue)?
Net Income: [amount] - What is the effective tax rate? Are one-time items inflating it?
Flag immediately:
Assess the quality and composition of assets, and whether the capital structure is sustainable.
Current Ratio: Current Assets / Current Liabilities - below 1.0 is a liquidity warning
Quick Ratio: (Cash + AR) / Current Liabilities - strips out inventory; below 0.8 is a stress signal
Debt-to-Equity: Total Debt / Total Equity - above 2.0 warrants scrutiny in most industries
AR Days (DSO): (AR / Revenue) x 365 - rising DSO means slower collections or revenue recognition issues
Inventory Days: (Inventory / COGS) x 365 - rising inventory days can signal demand weakness
Goodwill as % of Total Assets - high goodwill (>30%) reflects acquisition risk
Look for the balance sheet to tell a different story than the income statement. If AR is growing much faster than revenue, earnings quality is declining - customers are not paying.
The cash flow statement is where accounting choices cannot hide. Real businesses convert profit to cash.
Operating Cash Flow (OCF): [amount]
Net Income: [amount]
OCF / Net Income ratio: [calculate] - below 0.8 consistently is a red flag
Capital Expenditures: [amount] - how much is maintenance vs. growth capex?
Free Cash Flow: OCF - Capex = [amount] - the real measure of financial health
Key patterns to flag:
Run these ratios and compare against prior periods and industry benchmarks:
Profitability
Liquidity
Leverage
Efficiency

1. Reporting numbers without interpretation Bad: "Revenue was $10M, up from $8M last year." Good: "Revenue grew 25% but gross margin compressed from 42% to 37%, suggesting the growth was bought through pricing concessions or higher input costs - not through operating leverage."
2. Treating net income as the primary signal Bad: Leading with "the company is profitable" because net income is positive. Good: Cross-check OCF against net income. Positive net income with negative OCF means profit is not converting to cash - a red flag for earnings manipulation or structural problems.
3. Looking at ratios without trend or benchmark Bad: "The current ratio is 1.4." Good: "The current ratio is 1.4, down from 2.1 two years ago and below the industry median of 1.8. Liquidity is deteriorating."
4. Missing the cash flow statement Bad: Reviewing only the income statement and balance sheet. Good: The cash flow statement is the most manipulation-resistant of the three. Always read it last to validate what the other two are saying.
5. Ignoring footnotes Bad: Treating the face of the statements as complete. Good: Revenue recognition policy, lease commitments, contingent liabilities, and related-party transactions live in the footnotes. Material issues are often disclosed there and nowhere else.
