1. Revenue: Revenue, or sales, is the total amount of money generated by the sale of goods or services related to the company's primary operations.
2. Net Profit Margin: This is the percentage of revenue that is left over after all costs have been deducted. It’s an important indicator of the company's profitability.
3. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization): This is a measure of a company's operating performance. It's essentially net income with interest, taxes, depreciation, and amortization added back in.
4. Cash Flow: Cash flow is the net amount of cash and cash equivalents being transferred into and out of a company. Positive cash flow indicates that a company's liquid assets are increasing, providing it with more cash to cover debts, reinvest in its business, return money to shareholders, pay expenses, and provide a buffer against future financial challenges.
5. Working Capital: This is the difference between a company’s current assets and current liabilities. It’s an important measure of a company's operational efficiency and short-term financial health.
6. Debt to Equity Ratio: This ratio is used to measure a company's financial leverage and is calculated by dividing its total liabilities by shareholder equity. It indicates the relative proportion of shareholders' equity and debt used to finance a company's assets.
7. Current Ratio: This is a liquidity ratio that measures whether a firm has enough resources to pay its debts over the next 12 months. It compares a firm's current assets to its current liabilities.
8. Return on Equity (ROE): This is a measure of financial performance calculated by dividing net income by shareholders' equity. It's a measure of profitability that compares the profit a company generates to the shareholders' equity.
9. Gross Profit Margin: This is a company's total sales revenue minus its cost of goods sold, divided by the total sales revenue, expressed as a percentage. It represents the proportion of each dollar of revenue that the company retains as gross profit.
10. Return on Investment (ROI): This is a performance measure used to evaluate the efficiency or profitability of an investment, or to compare the efficiency of a number of different investments. ROI measures the amount of return on a particular investment, relative to the investment’s cost.

These are just a few of the key financial metrics that a CFO should be tracking. The specific metrics that are most relevant can vary significantly depending on the company's industry, size, stage of growth, and strategic goals.
