Reading a company's financial statements

You walk into a doctor's office. The doctor checks your pulse, your temperature, and your blood pressure. Three different numbers, each telling something different about your health.

A company's annual report works the same way. It contains three separate financial statements, each answering a different question about the business:

• The income statement answers: Did the company make a profit during the period?
• The balance sheet answers: What does the company own and owe right now?
• The cash flow statement answers: Where did cash come from and where did it go?

These statements exist because a single number can't capture the whole picture. The reporting period — typically a year or a quarter — is the window of time the statements cover. The income statement and cash flow statement describe flows over that period, while the balance sheet is a snapshot at the end of the period.

Crucially, the income statement uses accrual accounting: revenue is recorded when it's earned, not when cash arrives. Expenses are matched to the revenue they helped generate. This means profit shown on the income statement is not the same as cash in the bank. The cash flow statement fills that gap.

Different stakeholders rely on different statements. Investors focus on the income statement for profitability trends. Banks look at the balance sheet for solvency. Managers use the cash flow statement to plan liquidity. Understanding what each statement tells you is the first step to making sense of any annual report.

You already know the income statement, balance sheet and cash flow statement each answer a different question. Now you need to stop treating the income statement like a bank statement. A company that looks profitable on paper might be starved of cash, and a cash-rich company might be reporting a loss. The reason is accrual accounting.

Under accrual accounting, revenue is recorded when it is earned — when you have delivered the goods or service and the customer is obliged to pay — not when the cash lands in your bank account. Similarly, expenses are recorded when they are incurred to generate that revenue, not when the bill is paid. This is the matching principle: match the cost of earning revenue to the revenue itself in the same period.

Three common accrual adjustments keep the income statement honest:

• Receivables: You delivered the work but haven't been paid yet. The income statement shows the revenue; the balance sheet shows an asset (accounts receivable). Later, when cash arrives, the asset converts to cash — no extra revenue.
• Payables: You received a service or supply but haven't paid the invoice yet. The income statement shows the expense; the balance sheet shows a liability (accounts payable). Paying later reduces cash and removes the liability.
• Prepayments: You paid cash upfront for something that covers future periods (e.g., insurance premium). The balance sheet records an asset (prepaid expense) and releases a portion to the income statement as an expense each period.

These adjustments exist to give you a truer picture of performance in a given period, not to hide cash problems. A company can show a large profit while its cash is tied up in receivables, or show a loss while it has deferred revenue (cash received but not yet earned).

Open any annual report and you will see three numbers that never change the way they relate: Assets, Liabilities, and Equity. The accounting equation states that Assets = Liabilities + Equity. This is not a coincidence—it is the inescapable result of how every single transaction is recorded.

Think of the equation as a snapshot of what the company owns (assets) and who provided the money to buy those assets. Liabilities are claims by creditors; Equity is the owners' residual claim. Every transaction changes at least two accounts, always keeping the equation in balance. For example, if a company buys inventory with cash, one asset (inventory) increases and another asset (cash) decreases—the total stays the same. If it borrows money, both assets (cash) and liabilities (loan) increase by the same amount.

Equity is not a pile of cash. It consists of the owners' original investment plus retained earnings (profits kept in the business, minus any dividends). Profits increase equity through revenue, and losses decrease it through expenses. The equation forces you to see that a company's health depends on how it finances its assets, not just on how much cash it has.

You learned in "What the three statements are and why they exist" that every public company publishes three core financial statements. Now you need to be able to open any annual report and immediately say which statement answers which question. Here's the cheat sheet:

• Income statement answers: Did the company make a profit? It shows revenue, expenses, and net income over a period (a quarter or year).
• Balance sheet answers: What does the company own and owe right now? It lists assets, liabilities, and equity at a single point in time.
• Cash flow statement answers: Where did cash come from and where did it go? It tracks actual cash inflows and outflows from operations, investing, and financing.

Open an annual report and the first thing you hit is a date line: For the year ended January 31, 2025 or As of December 31, 2024. You already know the three statements answer different questions — now look at the dates stamped on them, because those dates do two different jobs.

Every set of statements is tied to a reporting period — the span of time it covers. The income statement and cash flow statement cover a stretch of time, so they read for the year ended… or for the three months ended…. The balance sheet is a photograph taken at one instant, so it reads as of…: the position at the close of business on that date, nothing more.

The fiscal year is the 12-month period a company chooses for its accounting. Many companies use the calendar year, but plenty do not. Retailers often end their fiscal year in late January, so the holiday season lands inside one reporting year and the books close after inventory is cleared. Apple ends its fiscal year in late September, timed to its product cycle. The rule is that the year-end must be consistent and disclosed.

Here is the trap. A fiscal year is named after the calendar year in which it ends. A retailer whose year ends January 31, 2025 calls that period fiscal 2025 even though almost all of it fell in 2024. Its Q1 runs February through April — not January through March. When you compare two companies, compare periods that actually line up, not labels that sound alike.

You already know the three financial statements: the income statement, balance sheet, and cash flow statement. Each one answers a different question about a company's health. But who actually reads them? Different stakeholders—investors, lenders, managers, and regulators—each have a primary focus.

• Investors care most about profitability and growth, so they start with the income statement.
• Lenders want to know if the company can repay its debts, so they turn to the balance sheet.
• Managers need to ensure the business has enough cash to operate day-to-day, so they watch the cash flow statement closely.
• Regulators check for compliance with accounting rules, so they review all three but particularly the notes and disclosures.

In this lesson, you'll practice explaining these connections out loud—just as you would in a real business conversation.

You open an annual report and see a table that starts with Revenue at the top and ends with Net income at the bottom. Between them, something subtracts every cost of running the business. If you can't read that sequence, you can't tell whether a company is making money from its actual operations or just from a one-time tax benefit. The income statement is a waterfall: each line removes a specific category of cost, and you need to know which pool each cost belongs to.

This lesson gives you a mental map of that waterfall. Once you know the layers, you can look at any income statement and immediately see where the money is being earned and where it is leaking.

You spot a company that looks like a rocket ship: revenue up 25%, earnings up 30%. Then you check the cash flow statement and see cash from customers barely moved. Why? The cash never arrived—the revenue was booked but not collected. That gap is the most common clue that a company is recognizing revenue too early or on fake transactions.

Revenue recognition under IFRS 15 follows a five-step model: (1) identify the contract, (2) identify performance obligations, (3) determine the transaction price, (4) allocate the price, (5) recognize revenue when control transfers. Two common pitfalls within this model are bill-and-hold arrangements (where revenue is booked before delivery) and channel stuffing (shipping excess inventory to distributors near quarter-end). Both inflate the top line without genuine cash flow.

You've already traced revenue down to gross profit. Now you're looking at the next section of the income statement: operating expenses. These are the costs of running the business that aren't directly tied to making the product — things like sales team salaries, office rent, marketing, and research. After subtracting operating expenses from gross profit, you get EBIT (Earnings Before Interest and Taxes), also called operating income. EBIT shows how profitable the core business is, before financing costs and taxes. It's a key measure because it isolates the operating performance from how the company is funded.

You've traced revenue down to EBIT (earnings before interest and tax). Now you cross the below‑the‑line items — interest expense and income tax — that transform operating profit into the number that actually belongs to shareholders: net income. These two deductions are not optional; every company that borrows money or pays taxes faces them. The order matters: interest is subtracted first, then tax is calculated on the result.

You already know that net income is the bottom line, but not all of it comes from making or selling products. A company might earn interest on cash it sits on, sell a factory for a gain, or pay a fine for a lawsuit – these are all real, but they aren’t the core business. The distinction between operating and non-operating items is what allows you to see whether profit is driven by the company’s actual operations or by one‑time events, investment returns, or financing decisions.

Operating items come from the company’s main business activities: selling goods or services, paying employees, buying inventory. They are expected to continue year after year. Non‑operating items are everything else – interest income, gains or losses on asset sales, foreign‑exchange adjustments, restructuring charges. They are unpredictable and often non‑recurring.

To judge a company’s health, you almost always look at operating income (EBIT) first. Net income can be inflated by a lucky asset sale or depressed by a one‑time writedown, but operating income tells you whether the core business is earning money.

A balance sheet is a snapshot — it shows what a company owns and owes at a single moment, unlike the income statement you've already read, which covers a whole period. The picture it paints hangs on one rule: Assets = Liabilities + Equity. Everything on the left side of the balance sheet is something the company controls; everything on the right is how it was paid for — either borrowed (liabilities) or invested by owners (equity).

Walk through a real balance sheet and you'll learn to spot a company's financial health at a glance.

You open the annual reports of two home-furnishing retailers. Both sell the exact same sofas from the same factory, yet one reports a gross margin of 42% and the other reports 38%. The difference is not efficiency or pricing—it's how they value the sofa sitting in their warehouse.

Inventory valuation is the accounting rule that decides which cost flows into the cost of goods sold (COGS) and which stays on the balance sheet as inventory. The three main methods—FIFO (first-in, first-out), LIFO (last-in, first-out), and weighted-average cost—produce different COGS and ending inventory numbers when purchase prices change. That means the method you choose directly affects reported profit, income taxes, and key ratios like gross margin and inventory turnover.

This lesson gives you the tools to read any company's inventory note, adjust for method differences, and apply the lower-of-cost-or-market rule that keeps inventory from being overstated.

You've already read the balance sheet and seen that a company's assets include things like buildings, equipment, and vehicles. But those assets don't stay new forever. The company uses them up over time, and accounting needs a way to spread that cost across the years those assets produce revenue. That's depreciation (for tangible assets) and amortization (for intangible ones).

Here's the key twist: depreciation is a non-cash expense. The cash left the company the day it bought the asset. The depreciation entry on the income statement is just an allocation of that past cost. Net income goes down, but cash doesn't change. That's why you'll see references to EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) — it tries to isolate cash earnings by adding back that non-cash charge.

But there's a trap. If you add back all depreciation without asking whether the company will need to spend cash to replace the asset one day, you overstate the cash available. Maintenance capital expenditure is the real cash cost of keeping assets productive. A good analyst compares depreciation to actual capex.

FIFO stands for First-In, First-Out. It assumes that the oldest inventory items are sold first. In a period of rising prices, this means the cost of goods sold (COGS) is made up of older, cheaper costs, while the ending inventory consists of newer, more expensive costs.

Because COGS is lower, net income is higher under FIFO compared to LIFO or weighted-average in a rising price environment. This also leads to a higher tax liability, but for financial reporting, FIFO is the default method under IFRS and is widely used. It also tends to match the physical flow of goods for perishable items (e.g., groceries), where the oldest stock is sold first to avoid spoilage.

You already know that inventory valuation methods affect COGS and inventory balances. FIFO is the most common choice because it reports inventory at current costs and avoids the write-downs that LIFO can require.

LIFO (Last-In, First-Out) is an inventory valuation method that assumes the most recently purchased items are sold first. In a period of rising prices, this means cost of goods sold (COGS) reflects the highest recent costs, while the ending inventory on the balance sheet is valued at older, lower costs. The result: lower reported profit and lower taxable income. LIFO is not permitted under IFRS (International Financial Reporting Standards), so it is only used by companies reporting under US GAAP. The choice to use LIFO is primarily driven by tax savings in the US, where LIFO is allowed for tax purposes if also used for financial reporting. However, it can distort the balance sheet, as inventory values may be significantly understated compared to current replacement costs.

When you buy identical inventory items at different prices, which cost should you assign to the unit you sell? The weighted-average cost method (WAC) sidesteps the choice by averaging all costs.

How it works

At the end of a period, you calculate the weighted-average cost per unit once:

Weighted-average cost per unit = Total cost of goods available for sale ÷ Total units available for sale

Then you value every unit — whether sold or still in stock — at that same average cost.

A concrete example

Your beginning inventory is 100 units costing $10 each ($1,000 total). You buy another 200 units at $12 each ($2,400 total). You sell 150 units.

• Total cost available = $1,000 + $2,400 = $3,400
• Total units available = 100 + 200 = 300
• Average cost per unit = $3,400 ÷ 300 = $11.33 (rounded)
• Cost of goods sold (COGS) = 150 × $11.33 = $1,699.50
• Ending inventory = 150 × $11.33 = $1,699.50

Why use it?

WAC smooths out price spikes. It's the simplest method when inventory is homogeneous (e.g., fuel, grain, identical components) and you don't want the income statement bouncing with every purchase. If you're choosing between FIFO, LIFO and WAC, and prices are moderately volatile, WAC often gives a more predictable profit margin.

Straight-line depreciation spreads an asset's cost evenly over its useful life. It is the default choice for most financial statements because it is simple, predictable, and matches the steady consumption of many assets (like office furniture or buildings).

The formula is:

Annual Depreciation Expense = (Cost – Residual Value) ÷ Useful Life

• Cost is what you paid to acquire and prepare the asset (purchase price, shipping, installation).
• Residual Value (or salvage value) is the expected amount you could sell the asset for at the end of its life.
• Useful Life is the number of years the asset will be used in the business.

Every year, the same dollar amount is expensed on the income statement, and the asset's net book value on the balance sheet falls by that amount.

Declining-balance depreciation accelerates the expense, taking larger charges in the early years of an asset's life. Unlike straight-line, it does not subtract residual value from the cost at the start. Instead, annual depreciation = book value at the beginning of the year × a fixed rate (often 200% of the straight-line rate, called double-declining balance). Depreciation stops once the book value reaches the residual value.

This method matches expense to revenue when the asset generates more value early on — for example, a delivery truck. Compared to straight-line, it reduces reported income (and taxes) in the early years and increases it later.

Use this method when the asset's economic benefit declines over time. If benefits are steady, stay with straight-line.

You can already read a balance sheet as a list of what a company owns and owes. The next question is when it owns and owes it. A company that owns plenty but owns it all in machines it can't sell quickly can still run out of cash before payday. That's why every balance sheet splits each side into two buckets:

• Current — cash, or things that will turn into cash, or obligations that must be paid, within one operating cycle, usually one year.
• Non-current — things you'll still be using or still be paying off more than a year out.

On the asset side, current means liquidity: inventory that will sell, receivables customers will pay, cash itself, and short-term investments you could liquidate. Non-current assets are the long-lived productive base — property, plant, equipment, patents, and what you paid above book value for an acquisition (goodwill).

On the liability side, current means obligations due within the year: supplier invoices, wages owed, short-term loans, and the slice of a long-term loan that's due this year. Non-current liabilities are the debts with maturities beyond a year — the rest of that loan, bonds, deferred tax.

The classification is about timing, not size. Amazon carries billions of non-current assets and still runs a positive working capital position. A startup with one million in current assets and one point two million in current liabilities is technically healthy on paper except for the fact that the shortfall is due soon. Subtracting current liabilities from current assets gives working capital — the cushion a business has to keep paying its bills while it waits for its inventory to become cash. The ratio form, current assets ÷ current liabilities, is the current ratio; above 1 means the current bucket covers the due bucket.

One trap: a single line can straddle the boundary. The current portion of long-term debt is the chunk of a 10-year loan due in the next 12 months, and it is reclassified as current even though the rest of the loan stays non-current. Miss that line and your liquidity picture looks too good by exactly the amount you must pay next year.

Working capital measures the cash and near-cash resources a company has to run its day-to-day operations. The formula is simple: Current Assets – Current Liabilities. Current assets include cash, accounts receivable, and inventory. Current liabilities include accounts payable, short-term debt, and accrued expenses.

Positive working capital means the company can cover its short-term obligations with the assets it expects to convert to cash within a year. Negative working capital signals a liquidity squeeze – the company may struggle to pay suppliers or employees. However, some businesses (like retailers) can operate with negative working capital because they collect cash from customers before paying their own bills. The key is to compare working capital across time and against industry peers.

Working capital isn't a perfect measure on its own. A company with very high working capital may be hoarding cash or carrying too much inventory, which drags on returns. The goal is to keep working capital at a level that supports operations without wasting resources.

From the balance sheet you already know that assets minus liabilities equals shareholders' equity. That number is the owners' residual claim—what would be left if the company paid off everything it owes. But equity isn't one pile of money; it's built from several accounts that each tell a different story.

Common stock and additional paid-in capital – When a company sells shares to investors, the par value (a nominal amount like $0.01 per share) goes into common stock. Any amount above par goes into additional paid-in capital (APIC). Together they represent the capital contributed by shareholders.

Retained earnings – This is the accumulated net income that the company has kept, minus any dividends paid. It links the income statement to the balance sheet: profit flows into retained earnings, and losses reduce it.

Treasury stock – When a company buys back its own shares, it records this as a negative amount in equity. It reduces the total equity because the company is returning capital to shareholders.

Other components – Some companies have accumulated other comprehensive income (unrealized gains/losses on investments, foreign currency translation, etc.) and noncontrolling interest (the portion of a subsidiary not owned by the parent). These are beyond your immediate scope, but know they exist.

Equity is a book value—it reflects historical transactions and accounting rules, not what the company is worth today on the stock market.

Net income isn't cash. A company can report a healthy profit yet be strapped for cash because it spent money on inventory, bought equipment, or paid down debt. The cash flow statement is the bridge between the income statement’s accrual-based profit and the actual cash that moved in and out. It answers one question: Where did the cash come from, and where did it go?

It splits every cash movement into three buckets:

• Operating activities – cash from selling goods and services, after adjusting for non-cash items like depreciation and changes in working capital.
• Investing activities – cash spent on or received from long-term assets (equipment, acquisitions, investments).
• Financing activities – cash from or repaid to lenders and shareholders (debt, equity, dividends).

When you add the net change from all three to the cash balance at the start of the period, you get the cash balance at the end – the same number you see on the balance sheet.

You already know how to read the cash flow statement; this node pits two of its numbers against each other. Operating cash flow (OCF) answers "did operations generate cash?" It does not answer "can the company hand that cash to shareholders?" A manufacturer can report $180M of OCF and still have nothing left over, because $170M went to replace aging machines. Free cash flow (FCF) is the adjustment that reveals what's left:

FCF = Cash from operations − Capital expenditures

Both numbers are already on the cash flow statement. Cash from operations is the bottom line of the operating section. Capital expenditures are in the investing section, usually as "purchases of property, plant and equipment." Not every investing outflow is capex: buying another company is an investing outflow, but FCF does not subtract it.

Read the sign carefully. Capex appears as a negative number on the statement; in the formula you subtract the absolute dollar amount. A positive OCF with larger capex gives negative FCF — the business generated cash but spent more than it generated on the assets it needs.

FCF is the cash available for dividends, share buybacks, debt repayment, acquisitions or a rainy-day balance. That is why it is called discretionary. OCF looks past the income statement's non-cash items; FCF looks one step further, past the cash the business must feed back into itself.

You have net income from the income statement, but that number includes non-cash items like depreciation and gains on asset sales. Cash hasn't moved for those. The indirect method starts with net income and adjusts it to show actual cash from operations. You'll work through three kinds of adjustments: non-cash expenses, gains/losses, and changes in working capital.

You already know that operating cash flow adjusts net income for changes in working capital. The cash conversion cycle (CCC) puts a number on exactly how long cash is tied up in that process — from the day you pay for inventory to the day you collect cash from customers.

The formula is simple:

CCC = Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) – Days Payable Outstanding (DPO)

• DIO: how many days on average inventory sits before it is sold.
• DSO: how many days on average it takes to collect payment after a sale.
• DPO: how many days on average you delay paying your own suppliers.

A shorter cycle means cash moves faster — less capital is tied up, reducing the need for borrowing. A longer cycle signals potential trouble: inventory is piling up, customers are slow to pay, or you are paying suppliers too early. Some businesses even run negative CCC (e.g., collect cash before they must pay suppliers), which is a strong liquidity advantage.

You do not need to compute each ratio from scratch — they are often reported or easily derived from the balance sheet and income statement. The CCC ties the three working capital pieces together into one actionable number.
