Silicon Laboratories Inc. reported revenue of $784.8 million in fiscal 2026, after growing 1.3% a year over the previous 9 years. Its operating margin narrowed from 9.5% in 2016 to -9.0%. Of the $1.1 billion its operations generated over 10 years, 220.1% went to buybacks and 53.9% to acquisitions; the share count fell 22.8%. On the accounting screens, it passes 5 of 8 Piotroski tests, its Altman Z'' of 11.34 is in the safe zone and its Beneish M-score is below the -1.78 line; 1 of the six cross-checks between its statements fires.

Is it growing?

Revenue and the operating income it turns into. Growth that does not reach operating income is growth bought with margin.

RevenueOperating income

Compound growth a year
	3 yrs	5 yrs	9 yrs
Revenue	-8.5%	+9.0%	+1.3%
Free cash flow per share	-14.2%	-5.4%	-3.6%
Shares	-3.2%	-5.9%	-2.8%

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.

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.

Net debt

Net debt ÷ EBITDA: —
Interest coverage: -72× operating income ÷ interest
Current ratio: 4.69 current assets ÷ current liabilities
Cash conversion cycle: 80 days collects in 30d, stock 106d, pays in 56d

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?

11.34safe zone

Working capital ÷ assets 0.42 × 6.56+2.74
Retained earnings ÷ assets 0.74 × 3.26+2.41
Operating income ÷ assets -0.06 × 6.72-0.37
Equity ÷ liabilities 6.26 × 1.05+6.57

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.

Beneish M-score

Do the accounts resemble those of companies that manipulated their earnings?

-3.07below the -1.78 line

Receivables vs sales 0.88+0.81
Gross margin slipping 0.92+0.48

Slower depreciation 1.01+0.12
Overheads vs sales 0.89-0.15
Profit not in cash -0.13-0.59
Leverage rising 1.41-0.46

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.

The effective tax rate is -12.1%.

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.

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.

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.
