Three Financial Statements and Linkages Interview Questions & Walkthrough

The Income Statement (P&L) shows a company's profitability over a period (quarter or year). Structure: Revenue - Cost of Goods Sold = Gross Profit. Gross Profit - Operating Expenses (R&D, SG&A) = EBITDA (or EBIT if you subtract D&A). EBIT - Interest Expense = EBT (earnings before tax). EBT - Tax = Net Income.

Key metrics: Gross Margin = Gross Profit / Revenue (measures pricing power and production efficiency). Operating Margin = EBIT / Revenue (measures operational efficiency). Net Margin = Net Income / Revenue (measures bottom-line profitability after all costs). In interviews, analysts care most about EBITDA and operating margin because they're less distorted by financing and tax decisions.

Understanding the P&L is essential for valuation. Revenue growth and margin expansion or contraction are the primary drivers of value creation. If a company grows revenue 20% annually but margins decline, it might not be creating value. Always scrutinise: is growth coming from volume or price? Is margin declining due to competitive pressure or investments in growth?

The Cash Flow Statement shows actual cash movements, unlike the P&L which uses accrual accounting. Structure: Operating Cash Flow (from business operations) + Investing Cash Flow (buying/selling assets) + Financing Cash Flow (debt, equity issuance/repayment) = Net Change in Cash.

Operating Cash Flow starts with Net Income and adds back non-cash expenses (depreciation, amortisation), adjusts for working capital changes (if receivables increase, it's a use of cash; if they decrease, it's a source). Operating cash flow is the cash generated by the core business and is most important for valuation.

Investing Cash Flow reflects capital expenditures (CapEx) and acquisitions. Free Cash Flow = Operating Cash Flow - CapEx. This is what's available to debt holders and equity holders. If operating cash flow is strong but CapEx is high, free cash flow might be weak.

Financing Cash Flow shows debt issuance/repayment and equity issuance/dividends. Negative financing cash flow (paying down debt, distributing dividends) is good — the company is returning capital. Positive financing cash flow (raising debt) could signal cash constraints or aggressive growth financing.

Net Income is not the same as cash. A company can be profitable on paper but have negative cash flow. Example: aggressive revenue recognition (recording revenue before collecting cash) or high CapEx investments. Always cross-check the P&L against the cash flow statement.

Working capital can be a trap. A high-growth company that extends payment terms to customers (high receivables) or builds inventory to meet demand needs lots of cash to fund growth, even if it's profitable. Amazon, for example, famously has negative working capital (pays suppliers after collecting from customers), which is economically valuable.

Depreciation and amortisation are non-cash expenses on the P&L but are mandatory adjustments on the cash flow statement. They reduce accounting profit but don't represent actual cash outflows. However, the assets eventually need replacement (capital expenditure), which is a real cash outflow.

Write-downs and impairments (e.g., goodwill impairment) are non-cash charges on the P&L that reduce accounting profit but don't affect cash. Conversely, stock-based compensation is non-cash but dilutes shareholders. Distinguish between non-cash P&L items and true economic losses.
