Share counts are in today's shares. The SEC's filings restate only recent years after a split, so these jumps were read as splits and the older years scaled to match — otherwise per-share figures would compare different units:
3-for-1 before fiscal 2021.
Is it growing?
Revenue and the operating income it turns into. Growth that does not reach operating income is growth bought with margin.

Falling shares are buybacks: each remaining share owns more of the company.
Does it earn more than its capital costs?
Margins say how much of each sale is kept; return on invested capital says how much the business earns on the money it needs to operate. Growth only creates value when that return is above the cost of the capital.
Needs a cost of capital, which comes from the valuation below.

Is the profit cash, and where does the cash go?
Net income is an accounting opinion; free cash flow is what was left in the bank after investing. Stock-based pay does not leave the bank — shareholders pay it through dilution — so it is shown taken off as well.

How strong is the balance sheet?
Debt is not bad in itself; debt the business cannot service in a bad year is. Net debt is debt minus cash, and below zero the company holds more cash than it owes.

Three classic screens of the accounts
Each asks a different question of the same statements — is it improving, does it look like a company heading for distress, do the accounts resemble ones that were manipulated. None is a verdict; each shows what moves it.

Where it misleads: it measures change, not level. An excellent business that stood still for a year scores low; a poor one recovering from a disaster scores high.
Altman Z''-score

Operating income ÷ assets 0.01 × 6.72+0.10
Equity ÷ liabilities 1.31 × 1.05+1.38
Where it misleads: buybacks. A company that returns so much cash that its equity turns small or negative sinks the last two ratios without being anywhere near bankruptcy. Banks and insurers do not fit the model at all.

Leverage rising 0.60-0.20
Where it misleads: fast growth and acquisitions. Sales growth carries a heavy weight, so a company growing 50% a year scores like a suspect without having done anything. It is a screen from a 1999 study, not an accusation.
Where the statements disagree
Cross-checks between the income statement, the balance sheet and the cash flow for the latest year, each with the benign reading and the worrying one.
Capital spending (440M) is well below depreciation (855M).
Benign
Mature assets, or a business that has become less capital-intensive.
Worrying
Under-investing: today's profit is being held up by consuming tomorrow's capacity.
What is it worth, under which assumptions?
A company is worth the cash it will generate, brought back to today. This model projects revenue with growth that fades over the years, applies a free cash flow margin, and discounts the result at the cost of capital. Every assumption says where it came from, and all of them can be changed.
With a free cash flow margin at or below zero in year ten, the business never generates cash for its owners and a DCF says nothing useful. Set a positive margin for year ten to see what it would take.
What it has filed lately
The last twelve months at the SEC, most important first: annual and quarterly reports, events, large holders and insiders.
Accounts from the company's own SEC filings; lines some companies do not report are shown as a dash rather than estimated. The risk-free rate is the 10-year US Treasury yield. A DCF is a way of making assumptions explicit, not a forecast: it states what the company would be worth if the assumptions held. The scores are screens that point where to look, not verdicts. Nothing here is a recommendation to buy or sell.
