Reading the three financial statements

The income statement: performance over a period

A film, not a photograph: it covers a quarter or a year. It starts with revenue, what customers were billed under accounting rules (not necessarily what they paid yet: that distinction is accrual accounting, and it is why the cash flow statement exists). Costs then come off in layers, each layer answering a sharper question. Here is a complete miniature, our running company for this guide:

revenue                              500.0
- cost of goods sold                (300.0)
gross profit                         200.0     gross margin 40%
- SG&A                               (90.0)
- R&D                                (35.0)
operating income (EBIT)               75.0     operating margin 15%
- interest expense                   (10.0)
pre-tax income                        65.0
- taxes (21%)                        (13.7)
net income                            51.3     net margin 10.3%

Each layer divided by revenue is a margin, and margins are how companies of different sizes become comparable. Alpine's 40% gross margin says the product itself earns well; the drop to a 15% operating margin says overhead and R&D absorb most of it. The analytical move is never reading one margin alone: it is the five-year trend (is pricing power holding through inflation?) and the peer comparison (is 15% good for tool makers? For enterprise software it would be alarming).

The balance sheet: position at an instant

A photograph taken on the period's last day, organized by one equation that cannot not balance:

ASSETS                                LIABILITIES + EQUITY
cash                     60           accounts payable          45
accounts receivable      85           short-term debt           20
inventory                95           long-term debt           180
property & equipment    240           TOTAL LIABILITIES        245
goodwill & intangibles  120
                                      shareholders' equity     355
TOTAL                   600           TOTAL                    600

assets = what it OWNS.  liabilities = what it OWES.
equity = the residual: what would remain for owners.

• Assets are ordered by how fast they turn into cash: cash, then receivables (what customers owe), then inventory, then plant and equipment, then goodwill: the premium paid over identifiable value in past acquisitions, an asset you could never sell.
• Liabilities are ordered by when they come due, and the split matters: Alpine owes $65M within a year against $145M of liquid-ish current assets, a comfortable ratio. The debt maturity schedule in the footnotes says WHEN the $180M long-term debt actually arrives.
• Equity accumulates history: capital paid in at issuance plus every profit ever retained (retained earnings) minus every dividend and buyback. Buybacks can even drive equity negative while the business thrives; book equity is an accounting residual, not a valuation.

The balance sheet is where risk lives: leverage (net debt of $140M against, as we will see, EBITDA of about $105M, so ~1.3x, a conservative level), liquidity, and asset quality (goodwill is 20% of assets here; at 50%+ a company is a stack of past deals waiting for a write-down).

The cash flow statement: where the money went

OPERATING
net income                           51.3
+ depreciation & amortization        30.0     non-cash, add back
- increase in receivables           (12.0)    customers owe more
- increase in inventory              (8.0)    cash sits on shelves
+ increase in payables                5.0     suppliers financing us
cash from operations                 66.3

INVESTING
capital expenditure                 (40.0)
cash from investing                 (40.0)

FINANCING
debt repaid                         (10.0)
dividends paid                      (15.0)
cash from financing                 (25.0)

net change in cash                    1.3     (-> the balance sheet's cash line)
free cash flow ≈ 66.3 - 40.0       = 26.3

Three sections, three verbs: operating (cash from running the business, reconciling the earnings opinion back to fact), investing (cash spent on the future), financing (cash to and from the people funding it). The SHAPE tells the story before any number: a healthy mature company generates in operations, spends some in investing, returns the rest in financing, exactly Alpine's shape. A young company burns in operating and raises in financing. A company funding dividends with new debt, or "generating" cash by starving capex, is visible here and nowhere else.

Note the working-capital lines. Alpine earned $51.3M but collected less: receivables grew $12M (sales billed, not yet paid) and inventory absorbed $8M. This is the accrual gap in action, and watching it IS cash flow analysis: FCF conversion (free cash flow over net income, here a soft 51% this year because of the working capital build) is the honesty ratio.

How the three tie together

net income (IS)          -> opening line of the CFS
                         -> adds to retained earnings in equity (BS)
depreciation (IS)        -> added back on the CFS (non-cash)
                         -> reduces property & equipment (BS)
capex (CFS, investing)   -> increases property & equipment (BS)
                         -> becomes future depreciation (IS)
ending cash (CFS)        -> IS the cash line (BS)
debt raised/repaid (CFS) -> moves the debt lines (BS)
                         -> changes future interest (IS)

The statements are one machine, and no event touches only one of them. Sell $10 of inventory for $18 on credit: revenue +18 and COGS +10 on the income statement (profit +8, ignoring tax); receivables +18 and inventory −10 on the balance sheet (equity +8 keeps it balanced); and on the cash flow statement, nothing yet, because no cash moved: net income +8 arrives at the top but is fully reversed by the receivables build. Profit without cash, legitimately, until the customer pays.

The classic: walk $100 of depreciation through all three

Every banking interview asks it, because it proves you see the machine. Depreciation rises by $100 (tax rate 21%):

• Income statement. EBIT falls $100; taxes fall $21; net income falls $79.
• Cash flow statement. Start $79 lower, but add back the $100 (non-cash): operating cash flow ends $21 HIGHER. Depreciation raised cash flow, via the tax shield.
• Balance sheet. Property & equipment down $100; cash up $21; assets net −79. Equity down $79 via retained earnings. Balanced.

The moral generalizes: non-cash charges cut earnings but help cash (through tax), which is why cash-focused investors shrug at write-downs the market panics over, and why EBITDA exists at all.

The ratios professionals read first

DuPont: taking ROE apart

ROE = net margin x asset turnover x leverage
    = (NI/rev)   x (rev/assets)  x (assets/equity)
    = 10.3%      x 0.83          x 1.69           = 14.4%

The point of the decomposition is that the same ROE can be earned three different ways, and they deserve different multiples: a luxury brand earns it through margin, a discounter through turnover, a bank through leverage. When ROE changes, DuPont names the culprit: an ROE "improvement" that is entirely a leverage increase is risk being added, not quality: the decomposition catches what the headline hides.

Red flags, with the mechanism behind each

• Earnings growing, operating cash flat. The gap must live somewhere: usually receivables (aggressive recognition, or straining customers) or inventory (production ahead of demand). Both come home. This divergence preceded most famous accounting blowups.
• Receivable days stretching. Sales are being pulled forward with loose terms, or customers are struggling. Either way, revenue quality is falling before revenue does.
• Inventory outgrowing sales. Demand softening before management admits it, or an obsolescence write-down being deferred.
• The annual "one-time" charge. A restructuring every single year is not one-time; it is the business model, and adjusted earnings that exclude it every year are fiction with a reconciliation.
• Capitalizing what peers expense. Moving costs from the income statement to the balance sheet (aggressive software capitalization is the classic) inflates current profit and builds a future write-down.
• Goodwill dominating assets. The company is a stack of past acquisitions; an impairment is an admission arriving years late, and the interesting question is what operating numbers the deals were bought on.
• Debt maturing soon into weak liquidity. The balance sheet has a calendar in the footnotes. A refinancing cliff in a shut credit market turns a solvency non-issue into a bankruptcy.
