NRG Energy, Inc. reported revenue of $30.3 billion in fiscal 2025, after growing 14.6% a year over the previous 9 years. Its operating margin widened from 0.4% in 2016 to 6.1%. Of the $13.0 billion its operations generated over 10 years, 53.6% went to buybacks and 34.6% back into the business; the share count fell 37.0%. On the accounting screens, it passes 5 of 7 Piotroski tests and its Altman Z'' of 1.86 is in the grey zone; none 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.

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: 2× operating income ÷ interest
Current ratio: 1.64 current assets ÷ current liabilities

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?

1.86grey zone

Working capital ÷ assets 0.18 × 6.56+1.15
Retained earnings ÷ assets 0.07 × 3.26+0.22
Operating income ÷ assets 0.06 × 6.72+0.43
Equity ÷ liabilities 0.06 × 1.05+0.06

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?

The accounts lack too many of the lines it needs.

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.

None of the six cross-checks fires for the latest year: receivables and inventory move with revenue, profit turns into cash, investment keeps up with depreciation, the tax rate is ordinary and debt is moderate.

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.

5,000 valuations, each with growth, final margin, discount rate and growth forever drawn at random around the values on the left (spreads of 3.0%, 2.0%, 1.0% and 0.5%). Not a probability — the spreads are assumptions too — but an honest picture of how wide the answer is.

10th percentile$196.69

Median$309.25

90th percentile$458.02

Half of the simulations land between $248.03 and $380.20; one in ten below $196.69, one in ten above $458.02.

Does the long run make sense?

7.8×The terminal value prices the business in year 10 at 7.8 times that year's EBITDA.
Free growthIn year 10 free cash flow is at or above after-tax operating profit, yet the model grows 2.5% forever. Growth needs reinvestment; this assumes it comes for free, which flatters the terminal value.
56%of the value comes from after year 10. The more of it, the more the answer depends on the part nobody can see.

The discount rate, taken apart

What shareholders demand (CAPM): 5.17% risk-free + 1.00 beta × 5.0% premium = 10.17%.
What lenders charge, after the tax saving on interest: 6.67% × (1 − 23.8%) = 5.08%.
Weighted by how much of each the company uses (book value (no price given)): 10.17%, the rate every future cash flow is discounted at.

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.
