Profitability shows whether revenue becomes durable profits. Look for stability over multiple cycles, not one quarter.
EPS (Earnings Per Share)
Profit allocated to each share. Core input for P/E and a key signal of earnings momentum.
Formula: Net Income / Weighted Avg Shares
Example: If net income is 2B and shares are 500M, EPS = 4.00.
Report fields: Income Statement: Net income attributable to common + weighted average shares (basic/diluted).
Gross Margin
Efficiency after direct production cost. Higher margins often indicate pricing power or product mix strength.
Formula: (Revenue - COGS) / Revenue
Example: Revenue 10B and COGS 6B gives gross margin = 40%.
Report fields: Income Statement: Revenue and Cost of Revenue (COGS), or Gross Profit if disclosed.
Operating Margin
Profitability after core operating expenses. Shows business model discipline before financing and taxes.
Formula: Operating Income / Revenue
Example: Operating income 1.8B on revenue 10B means margin = 18%.
Report fields: Income Statement: Operating Income (EBIT) and Revenue (quarterly or annual).
Net Profit Margin
Final profitability after all expenses. Useful for measuring bottom-line resilience across downturns.
Formula: Net Income / Revenue
Example: Net income 1.2B on revenue 10B gives net margin = 12%.
Report fields: Income Statement: Net Income and Revenue.
ROE (Return on Equity)
How effectively management compounds shareholder capital.
Formula: Net Income / Shareholder Equity
Example: Net income 1.2B and equity 6B gives ROE = 20%.
Report fields: Net Income from Income Statement; Total Shareholder Equity from Balance Sheet.
ROA (Return on Assets)
How efficiently total assets produce profit. Helpful for banks, manufacturers, and capital-heavy businesses.
Formula: Net Income / Total Assets
Example: Net income 1.2B and assets 20B gives ROA = 6%.
Report fields: Net Income from Income Statement; Total Assets from Balance Sheet.
