Adjusted EPS is a version of earnings per share that strips out one-time or unusual items to show what a company earned from its ongoing, core business operations. Unlike standard (GAAP) EPS, which follows strict accounting rules and includes every gain and loss, adjusted EPS removes items that management considers non-recurring so investors can compare performance from one quarter or year to the next on a more consistent basis.
How Adjusted EPS Differs From GAAP EPS
Every publicly traded company must report GAAP EPS, the earnings-per-share figure calculated under generally accepted accounting principles and filed with the SEC. GAAP EPS includes everything: regular operating profits, one-time windfalls, unusual charges, and accounting adjustments. That comprehensiveness is both its strength and its limitation. A one-time gain from selling a subsidiary, for instance, can cause GAAP EPS to spike in a single quarter even though the company’s day-to-day business didn’t change. Conversely, a large restructuring charge can make a perfectly healthy quarter look terrible.
Adjusted EPS (sometimes called “non-GAAP EPS,” “pro forma EPS,” or “ongoing EPS”) starts with the same net income figure but then adds back or subtracts items the company considers one-time or non-operational. The goal is an apples-to-apples comparison: if you’re trying to judge whether a business is earning more this year than last year, you want to filter out events that won’t repeat.
The Basic Calculation
The formula mirrors standard EPS but uses an adjusted net income number in the numerator:
Adjusted EPS = Adjusted Net Income รท Weighted Average Shares Outstanding
Adjusted net income is simply GAAP net income with specific items added back or removed. If a company reported $500 million in GAAP net income but took a $100 million write-down on an old factory, its adjusted net income would be $600 million (assuming the write-down is the only adjustment). Divide that by, say, 200 million weighted average shares, and you get an adjusted EPS of $3.00 versus a GAAP EPS of $2.50.
Some companies also adjust the share count, for example by excluding the dilutive effect of convertible debt or adding back the interest paid on that debt to the numerator so the result isn’t distorted by the conversion math. But the most significant differences between GAAP and adjusted EPS almost always come from what’s included in the income number, not the share count.
Items Companies Typically Exclude
There is no universal checklist. Each company decides which items to adjust, and those choices can vary across industries and even across quarters for the same firm. That said, the most common exclusions fall into a few categories:
- Asset write-downs and impairments: When a company marks down the value of goodwill, equipment, or other assets, that non-cash charge hits GAAP earnings but doesn’t reflect ongoing operations.
- Gains or losses from asset sales: Selling a division, a building, or a piece of machinery can create a large one-time gain or loss unrelated to regular business activity.
- Restructuring charges: Costs tied to layoffs, facility closures, or organizational overhauls are typically treated as non-recurring.
- Stock-based compensation: Many tech and growth companies exclude the non-cash expense of issuing stock options or restricted stock to employees, though this exclusion is more controversial than others.
- Litigation settlements: Large legal payouts or recoveries are usually one-time events.
- Changes in accounting estimates: Revisions to depreciation schedules, pension assumptions, or reserve calculations can shift reported earnings without any real change in operations.
- Loss provisions: Setting aside reserves for anticipated future losses can weigh on GAAP earnings in a single period.
The common thread is that each item is either non-cash, non-recurring, or both. Whether it truly qualifies is where judgment (and potential bias) enters the picture.
SEC Rules on Reporting Non-GAAP Measures
Because adjusted EPS is not standardized, the SEC imposes rules to prevent companies from using it to mislead investors. Under Regulation G, any time a public company discloses a non-GAAP financial measure, it must also present the most directly comparable GAAP measure and provide a quantitative reconciliation showing exactly how it got from one number to the other. That reconciliation is typically a table in the earnings release walking line by line through each adjustment.
When a non-GAAP figure appears in an actual SEC filing (a 10-K or 10-Q, for example), the requirements go further. The company must present the GAAP figure with equal or greater prominence, explain why management believes the non-GAAP number is useful to investors, and disclose any additional internal purposes for which it uses the measure. For forward-looking adjusted EPS guidance, the reconciliation must be quantitative to the extent possible without unreasonable effort.
These rules mean you should always be able to find a bridge between the adjusted and GAAP numbers. If a company quotes an adjusted EPS in a press release or investor presentation, look for the reconciliation table, usually at the bottom of the release or in the supplemental materials.
Why Companies Report Adjusted EPS
The primary argument is comparability. If a company sold a business unit last year and recorded a $2 billion gain, including that gain in year-over-year comparisons makes this year’s results look worse by default, even if the core business grew. Adjusted EPS lets management and analysts isolate the underlying trend. Analysts who build earnings models often prefer an adjusted number because it maps more cleanly to future projections; you wouldn’t project a one-time restructuring charge into next year’s forecast.
Adjusted EPS also helps when comparing companies within the same industry. Two retailers with identical operations might report very different GAAP EPS if one just completed an acquisition (triggering amortization of intangible assets) and the other didn’t. Stripping out acquisition-related costs can make the comparison more meaningful.
Why Investors Should Be Cautious
The biggest risk is that “adjusted” becomes a euphemism for “flattering.” Because there is no standard definition, management has discretion over which costs to exclude. A company could label a large operating expense as an “unusual charge,” strip it from adjusted earnings, and present a rosier picture. If a company seems to report “one-time” restructuring charges every single year, those charges may simply be a cost of doing business that keeps getting swept out of the headline number.
Stock-based compensation is a useful case study. Many companies exclude it because it’s a non-cash expense, but it has a real economic cost: it dilutes existing shareholders. Excluding it can make a company look significantly more profitable than it actually is on a per-share basis. Whether that exclusion is reasonable depends on how you think about the expense, and reasonable people disagree.
The gap between GAAP EPS and adjusted EPS itself tells a story. A small, stable gap suggests the adjustments are genuinely one-off. A large or growing gap over many quarters may signal that management is routinely flattering results. Comparing the two numbers over time is one of the simplest ways to evaluate whether the adjusted figure is trustworthy.
How to Use Adjusted EPS in Practice
When you see adjusted EPS in an earnings report, treat it as one input rather than the final word. Start by reading the reconciliation table to understand exactly what was excluded and whether those exclusions make sense to you. Then look at GAAP EPS alongside it. If both are trending in the same direction over several quarters, the adjusted number is probably giving you a cleaner signal rather than hiding problems.
Pay attention to whether analyst consensus estimates are built on GAAP or adjusted figures. Most Wall Street estimates for large companies are on an adjusted basis, which means the “beat” or “miss” you hear about on earnings day is usually measured against adjusted EPS. Knowing that helps you interpret headlines more accurately.
Finally, when comparing adjusted EPS across companies, check whether they’re making similar adjustments. One firm might exclude stock-based compensation while its competitor includes it, making a side-by-side comparison misleading unless you normalize for the difference.
