Editor’s Note: Today’s article makes the case for free cash flow as the most reliable test of a company’s financial health. The same test applies to income investing — a growing dividend is only as reliable as the cash flow behind it. Robert Rapier has spent 36 years applying exactly that discipline to essential-service stocks. His current portfolio of 41 holdings now averages 33% in annual yield on original investment — five positions above 100%. See how the math compounds →

It happens every quarter.

Corporate auditors spend countless painstaking hours tallying up sales, expenses and net profits over the past 90 days. Those figures, always prepared in strict adherence to Generally Accepted Accounting Principles (GAAP), are then filed as part of the SEC 10-Q.

You know it better as the quarterly earnings report.

But for 99% of investors, all that bean-counting means next to nothing. They skip right over it. Truth be told, so do most analysts and media pundits. They might give it a passing glance at most. You see, it’s not the unaltered GAAP earnings figure that matters most – but the one that has been doctored.

Take HP (NSDQ: HPQ).

Officially, the PC manufacturer just posted a second profit of $0.49 per share. But financial media outlets like Zacks and Barron’s reported earnings of $0.86 per share. That figure was comfortably ahead of the consensus analyst estimate of $0.72 — triggering a nice 12% rally in the stock.

So why the discrepancy? Where does the $0.86 come from. As you may have guessed, that revised figure is commonly referred to as adjusted earnings. As in, some things were added and others subtracted.

Most companies are happy to furnish a reconciliation table showing the exact adjustments. If you scroll to the bottom of the report, you’ll typically see line entries for asset impairment, restructuring charges, loss on disposal of subsidiaries and investment gains/losses.

These extraneous (non-recurring) items can make a substantial difference… meaning adjusted profits can be well above (or sometimes below) reported profits.

In dollar terms, HP’s adjusted earnings came in at $792 million, versus a reported figure of $450 million… a difference of $340 million.

Why does the market pay more attention to the adjusted figure? There are several reasons.

Picture a small fast-food chain that owns five restaurants. Four of them are solidly profitable, earning respective profits of $100,000, $150,000, $200,000 and $250,000 last year. Unfortunately, the fifth store was a drag on operations and showed a hefty loss of $300,000. So management decided to close that location at the end of the year on December 31, 2025.

On paper, the chain banked a net profit between the five locations of $400,000. But the money-losing restaurant has since been shuttered. All things equal, that move will add $300,000 to the bottom line starting in 2026. The loss was quite real, so it must be counted. But it won’t be part of the business going forward. So the fifth restaurant is classified as discontinued operations.

With that adjustment, the remaining four units earned $700,000. So that’s what investors key on.

Likewise, one-time gains should also be removed from the picture since they too are non-recurring. In the example above, maybe management parked $75,000 of its retained earnings into an undeveloped lot for a future location. But a buyer came along and offered $100,000 and a deal was made.

That $25,000 real estate windfall is nice. But can we count on it again next year? Not really, because it wasn’t generated by normal business operations. So it would be smart to deduct that realized investment gain to get a normalized earnings figure.

These are simplified examples, of course. In the real world, there are countless miscellaneous line entries: Legal settlements. Early debt retirement charges. Gains/losses on hedging instruments.

If we strip them out, then what’s left is a truer picture of the core business.

Verizon (NYSE: VZ) posted a GAAP profit of $0.55 per share last quarter. But that was after $0.54 in severance benefits and other “special items”. Without them, adjusted earnings for the telecom giant were $1.09 per share – almost double.

Do some companies abuse this system? You better believe it. Earnings can be bent, twisted and manipulated in all manner of ways. Some are perfectly legitimate, others merely a litany of excuses and gimmickry for coming up short quarter after quarter.

Thornton O’Glove explores this concept in great detail in his seminal book Quality of Earnings: The Investor’s Guide to How Much Money a Company is Really Making.

All of which is another reason why I focus primarily on cash flows. Even when accounting laws are scrupulously followed to the letter, earnings are clouded by intangible asset write-downs, property depreciation and a host of other non-cash entries.

The “non-cash” part there is important, understating (or overstating) how much money a company really takes in. Deducting a $15 non-cash charge from $100 leaves a net profit of $85. At least on paper.

Yet, the company still has $100 in its pocket to spend how it pleases.

By contrast, operating cash flows can’t be distorted. Subtract out capital expenditures, and you are left with Free Cash Flows (FCF). This is what Warren Buffett calls “Owner Earnings” – the real pool of cash that owners can use to pay dividends, repurchase stock, make acquisitions, or reinvest in new growth projects.

Look for efficient businesses with superior free cash flow yields, those capable of churning out more cash from every dollar of market capitalization. Like Texas Instruments (NYSE: TXN). The analog chipmaker has clearly prioritized this pursuit, boldly stating at the top of its investor relations page “we believe that long-term growth of free cash flow per share is the ultimate measure to generate value.”

It has delivered on that goal, producing a 97% increase over the past year… a big factor behind the stock’s recent advance into uncharted territory above the $300 level.

The discipline Nathan applies above — looking past reported numbers to the real cash flow underneath — is exactly what separates a reliable dividend from one that gets cut at the worst possible moment. Our colleague Robert Rapier has been applying that same test to essential-service stocks for 36 years at Utility Forecaster. His current portfolio of 41 holdings averages 33% in annual yield on his original investment — because the dividends are backed by the kind of genuine cash generation Nathan describes.
