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:
1-for-5 before fiscal 2022.
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.

Debt and liquidity
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.
Piotroski F-score
Is the business improving? Nine yes-or-no tests, this year against last.

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
Does the balance sheet look like those of companies that went bankrupt?

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.

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.
Receivables are growing 183% against revenue growing 99%.
Benign
A shift towards larger customers on longer terms, or sales concentrated at the end of the period.
Worrying
Sales are being made on looser credit, or revenue has been booked that may never be collected.
Inventory is growing 147% against revenue growing 99%.
Benign
Stocking up for a launch, or securing supply.
Worrying
Demand is softening; discounts or write-downs tend to follow.
The effective tax rate is -0.2%.
Benign
A favourable geographic mix, or legitimate tax credits.
Worrying
Not sustainable; projecting it forward inflates the valuation.
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.
Every Form 4 filed in the last twelve months, read line by line: 6 filings by 4 people. Open-market purchases and sales are counted apart from awards, option exercises and shares withheld for taxes.
Bought on the open market—none in the period
Sold on the open market$11.9M15 sale(s) by 4 insider(s)
Under pre-arranged plans80%of the sales followed a 10b5-1 plan set months earlier
A Form 4 says what happened, when, how many shares and at what price. It does not say why: a sale can be diversification, a tax bill or a plan fixed months earlier, and an award is pay, not a purchase. Nothing here is a reason to buy or sell anything.
Which large funds report holding it
From the Form 13F of the 28 institutions followed on this site, as of the end of their last reported quarter. A 13F is filed up to 45 days later and shows only long positions in US-listed shares.
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.
