Every finance and consulting interview eventually touches the three financial statements, the income statement, balance sheet, and cash flow statement, because they are how a business actually gets described in numbers. This deck is built for someone who has never opened a company’s annual report: it walks through what each statement shows, why they exist as three separate documents instead of one, and how a single transaction ripples across all three. By the end, you should be able to hear "walk me through the financial statements" and actually enjoy answering it.

You can look at only one of the three statements, and you need to know whether Ferrow Retail can pay its bills next month. Which do you pick, and what is each of the three actually for?
Balance sheet shows what you have now, income statement how you did, cash flow why cash moved.
You’d take the balance sheet, because it’s the only one that shows what the company holds and owes right now: cash in the bank, bills due shortly, debt coming up for repayment. The income statement is built to answer a different question, how profitable the company was over a stretch of time, and a profitable company can still run out of money. The cash flow statement explains where cash came from and went during that period, which tells you whether the business generates cash rather than whether it has any today.

Your staffer drops Ferrow Retail’s income statement on your desk and asks you to read it from the top line to the bottom line. What is each step telling you?
Each step down the income statement subtracts another layer of cost, ending at net income.
Revenue at the top is everything the company sold before any costs. Subtract cost of goods sold, the direct cost of making or buying the things that were sold, and you get gross profit. Subtract operating expenses, the cost of running the business itself like salaries, rent, and marketing, and you get operating income, which is profit from operations before financing and tax. Subtract interest on debt and taxes and you reach net income, the bottom line that belongs to the owners.

What’s the difference between cost of goods sold and operating expenses, and why does it matter which one a cost gets booked to?
COGS is the cost of the thing you sold, operating expenses are the cost of running the company.
Cost of goods sold is the cost tied directly to what was sold in the period: raw materials, factory labor, the wholesale price of inventory. Operating expenses are the costs of running the business regardless of any single sale, like head office salaries, rent, marketing, and research. Moving a cost between the two doesn’t change net income at all, but it does change gross profit, so a company that classifies aggressively can make its product look more profitable than a peer. Classification varies enough by company that you check the footnotes before trusting a comparison.

A client asks why your page shows three different margins for Calder Foods rather than just one. What does each margin tell her that the others don’t?
Gross, operating, and net margin show what’s left after each successive layer of cost.
A margin is just a profit line divided by revenue. Gross margin, gross profit over revenue, shows pricing power and how cheaply the company can make what it sells. Operating margin, operating income over revenue, adds the cost of actually running the business, so it captures how efficient the whole operation is. Net margin, net income over revenue, comes after interest and tax, so it reflects how much debt the company carries and where it pays tax. That’s why operating margin usually gives the cleaner read across peers.
Card 5 of 17
What does it mean when a balance sheet line is labeled current rather than non-current?
Current means settled within twelve months, non-current means everything longer.
Current means the item is expected to turn into cash or be paid off within twelve months: cash, receivables owed by customers, inventory on the shelf, payables owed to suppliers, and the slice of debt due this year. Non-current covers everything with a longer horizon, like factories and equipment, goodwill, and long-term borrowings. The split exists so a reader can see at a glance whether what’s coming due soon is covered by what’s turning into cash soon, which is the first thing anyone checks before worrying about the long-dated items.
Card 6 of 17
The Windmere Foods deal has a working capital adjustment built into the purchase agreement, and your associate asks you to explain what working capital actually measures before you build the mechanism into the model. What do you tell them?
Working capital is current assets minus current liabilities, a quick read on short-term liquidity.
Working capital measures how easily a company can cover its near-term obligations: current assets minus current liabilities. A positive number means the company has enough short-term assets, cash, receivables, inventory, to meet what it owes in the near future. Read the number against the business model rather than judging it by its sign. Supermarkets, restaurants and subscription businesses collect from customers before they pay suppliers, so they run negative working capital as a matter of course and it is a strength, not a warning. What diligence actually flags is an unexplained deterioration from how that particular business normally runs, or receivables and inventory swelling faster than sales. It is why working capital pegs and adjustments show up in almost every purchase agreement.

You're staffed on the Kestrel Components sale process, and the VP asks you to walk the client's newly hired CFO through how the three financial statements tie together before the first management presentation. What do you say?
Net income is the thread that stitches the income statement, balance sheet, and cash flow statement together.
You'd start with the income statement, which shows profitability over a period: revenue minus expenses equals net income. Then the balance sheet, a snapshot of what the company owns and owes at one specific moment, assets, liabilities, and equity. Then the cash flow statement, which tracks how cash actually moved during that same period. Net income is what ties them together: it flows into the cash flow statement's starting line and into retained earnings on the balance sheet.
Card 8 of 17
What are the three sections of the cash flow statement?
Operating, investing, and financing activities add up to explain exactly why cash changed.
Operating activities capture cash generated or used by the core business. Investing activities cover cash spent on or received from things like equipment or acquisitions. Financing activities capture cash from debt, equity raises, dividends, or buybacks. Add all three together in the model and you get the full explanation for why the cash balance changed over the period.
Card 9 of 17
How does depreciation affect the income statement differently than the cash flow statement?
Depreciation cuts net income as an expense, then gets added straight back on the cash flow statement.
Depreciation reduces net income on the income statement because it's recorded as an expense, even though no cash actually leaves the business that period. On the cash flow statement, it gets added back in the operating section, since that statement's whole job is to reflect real cash movement, not accounting expense, which is exactly the line the deal team double-checks first when a cash flow build doesn't tie out.

During diligence on the Talbrook Industries acquisition, the target's net income looks strong but its cash balance keeps falling. Your associate asks you to explain why the two numbers can diverge in the same period.
Net income books revenue the moment it's earned; cash flow only counts money that's actually landed.
Net income includes non-cash items like depreciation, and under accrual accounting it counts revenue as soon as it's earned, not when the cash actually arrives. Cash flow only counts money that has physically moved. That's exactly how a target can show a healthy profit on paper while its cash balance falls, if customers haven't paid yet or cash is tied up sitting in inventory, which is precisely the kind of gap diligence is meant to catch.
Card 11 of 17
Northbay Logistics earns 40 million and pays a 10 million dividend in the same year. Your associate asks what that does to equity on the balance sheet. What do you tell her?
Net income minus dividends is what actually gets added to retained earnings each period.
Equity rises by 30 million. Net income lands in retained earnings, the running total of every dollar of profit the company has kept since it was founded, and dividends are then subtracted from it. So opening retained earnings plus net income less dividends equals closing retained earnings. Note that a dividend never appears on the income statement, since it isn’t a cost of doing business but a distribution of profit already earned, and it shows up instead as an outflow in the financing section of the cash flow statement.
Card 12 of 17
Ferrow Retail grew revenue 30% but its operating cash flow fell. The associate says look at working capital. How does a change in working capital actually show up in cash flow?
Cash tied up in receivables and inventory is subtracted, cash owed to suppliers is added back.
The rule is simple once you see it: an increase in a current asset uses cash, and an increase in a current liability provides it. If receivables rise, customers have taken the goods but not paid, so that increase gets subtracted in the operating section. If inventory rises, cash went out to buy stock still sitting in a warehouse. If payables rise, the company is holding cash it hasn’t paid suppliers yet, so that gets added. Fast growth eats cash precisely because the buying and the lending come before the collecting.

The Overton Digital pitch materials quote an EV/EBITDA multiple, and the analyst next to you asks what EBITDA actually captures before it goes into the comp set. What do you tell them?
EBITDA adds interest, taxes, and D&A back to net income to isolate pure operating performance.
EBITDA stands for earnings before interest, taxes, depreciation, and amortization, essentially operating profit before the effects of financing decisions and non-cash accounting charges. It shows up everywhere in comps and LBO models because it lets you compare operating performance across companies with different capital structures or tax situations, stripping those differences away to leave the core business result.
Card 14 of 17
Your MD says the whole pitch rests on how much cash Calder Foods actually keeps, not what it books as profit. What is free cash flow, and how do you build it from the statements?
Free cash flow is what’s left after paying for the spending needed to keep the business running.
Free cash flow is the cash a business has left once it has paid for the capital spending it needs, meaning the money laid out on equipment, property, and software. The quickest version straight off the statements is cash from operating activities minus capital expenditures, both of which are printed lines. In models people often build unlevered free cash flow instead: operating income after tax, plus depreciation and amortization, less capital spending, less the increase in working capital. Definitions genuinely vary between firms, so say which one you’re using.
Card 15 of 17
Talbrook Industries’ operating income jumped 40%, but the footnotes mention a legal settlement and the sale of a factory. Why does that change how you read the number?
Strip out one-time items before you compare a year to last year or a company to its peers.
One-time or non-recurring items, things like a lawsuit payout, a restructuring charge, or a gain on selling a plant, sit inside the reported figures but say nothing about how the business will perform next year. Analysts pull them out to get a normalized number that can be compared across years and against peers, and the footnotes are where the detail to do that lives. Be skeptical while you do it: management has every incentive to label a recurring cost as one-time, which is why adjusted EBITDA add-backs get argued over line by line in diligence.
Card 16 of 17
An investor at the table says he doesn’t care about EBITDA. What’s the honest case against it, and when is it a poor stand-in for cash flow?
EBITDA ignores the capital spending, interest, and taxes a company genuinely has to pay.
Adding depreciation back treats worn-out equipment as if it were free, so a business that has to spend heavily on machinery just to stand still can show strong EBITDA while keeping almost no cash. It also ignores interest, which is a real payment for a company carrying debt, ignores tax, and ignores cash swallowed by working capital. On top of that it isn’t a defined accounting measure, so companies set their own adjusted definitions. It remains a useful screen for comparing operations, but free cash flow is the number that tells you what’s left.
Card 17 of 17
Your interviewer leans back and says depreciation goes up by 10, the tax rate is 25%, walk me through all three statements. Where do you start?
Net income falls by the after-tax amount, cash rises by the tax saved, and the balance sheet still ties.
Income statement first: operating income falls by 10, so pre-tax income falls by 10, taxes drop by 2.50, and net income falls by 7.50. Cash flow statement next: start at net income down 7.50, add back the full 10 of depreciation because no cash left the business, so cash from operations and the cash balance both rise by 2.50. Balance sheet last: cash is up 2.50 while plant and equipment is down 10, so assets fall 7.50, and retained earnings falls 7.50 too, so it balances. That 2.50 is the tax shield.
