EPS growth and revenue growth are frequently treated as interchangeable "growth" signals, but they can diverge sharply — and the divergence itself is informative. A company can grow earnings per share faster than revenue through margin expansion or share buybacks, neither of which is visible in a revenue growth screen alone. It can also grow EPS from a one-off item that has nothing to do with the operating business at all. Screening EPS growth well means understanding which of these is actually driving the number.

What EPS growth measures
EPS Growth (YoY) = (Current Period EPS − Prior Period EPS) ÷ Prior Period EPS
Where EPS (Earnings Per Share) = Net Income ÷ Diluted Shares Outstanding.
A company earning €2.20 per share this year versus €2.00 last year has grown EPS 10% year-over-year — even if net income itself grew by a different amount, because the share count can change independently of earnings.
Why EPS growth can diverge from revenue growth
Three distinct mechanisms can drive EPS growth faster or slower than the underlying revenue growth, and a screener that only shows the headline EPS growth number doesn't tell you which one is at work:
1. Margin expansion
If operating margin is expanding, net income — and therefore EPS — grows faster than revenue. A company growing revenue 8% with operating margin expanding from 15% to 18% can post EPS growth well above 8%, purely from operating leverage. This is a genuinely positive signal: it means the business is becoming structurally more profitable as it scales, not just bigger.
2. Share buybacks
Reducing the share count mechanically increases EPS even with flat net income — the same profit divided among fewer shares. A company with 0% net income growth and a 5% annual reduction in share count through buybacks will show roughly 5% EPS growth despite zero underlying earnings growth. This isn't necessarily a red flag (returning capital via buybacks is a legitimate use of cash), but it's a materially different situation from genuine operating growth, and a screen that can't distinguish the two is missing something important.
3. One-off items
Asset sales, litigation settlements, tax adjustments, and other non-recurring items can inflate or deflate a single period's net income and therefore EPS, without reflecting the ongoing earnings power of the business at all. A single-year EPS growth figure distorted by a one-off gain looks identical, at a glance, to genuine operating improvement.
Diagnosing which driver is behind an EPS growth number
The practical fix is checking EPS growth alongside the metrics that isolate each mechanism:
EPS growth > revenue growth, with expanding operating margin: Genuine operating leverage — the best-quality version of EPS growth outpacing revenue.
EPS growth > revenue growth, with flat operating margin: Likely driven by share count reduction (buybacks) — check trailing shares outstanding for confirmation. Not a bad signal, but a different one than margin-driven growth.
EPS growth well above what margin trend and buyback activity can explain: Likely includes a one-off item — check the income statement for unusual gains, tax benefits, or asset sales before treating the growth rate as representative of ongoing earnings power.
EPS growth < revenue growth: Either margin compression, share count dilution (new equity issuance, convertible securities, option exercises), or both — worth checking which, since dilution and margin compression carry different implications for the investment thesis.
Building an EPS growth screen
Basic EPS growth screen (headline filter, needs the diagnostic layer below to be reliable):
- EPS growth (YoY) > 15%
- Sort by: EPS growth descending
Quality-confirmed EPS growth screen (isolating margin-driven growth specifically):
- EPS growth (YoY) > 15%
- Operating margin: expanding YoY
- Revenue growth (YoY) > 0% (rules out EPS growth from a shrinking, cost-cut business)
- Sort by: EPS growth descending
EPS growth from capital return, not operations (a different, still legitimate thesis):
- EPS growth (YoY) > 10%
- Revenue growth (YoY): roughly flat (0–5%)
- Operating margin: roughly stable
- (The gap between EPS growth and revenue growth here is most likely explained by buybacks — worth confirming against share count trend)
EPS growth vs. revenue growth: which matters more?
Neither is strictly more important — they answer different questions, and screening for both together is more informative than either alone:
Revenue growth tells you whether the underlying business is expanding — more customers, more volume, more pricing power. It's a cleaner signal of genuine demand, less exposed to capital allocation decisions or accounting effects.
EPS growth tells you what shareholders are actually experiencing per share — which incorporates revenue growth, margin trend, and capital allocation (buybacks, dilution) all together. It's closer to "the number that matters to your return" but is a noisier, more composite signal precisely because several different things can drive it.
A screen combining both — strong revenue growth and strong EPS growth — is a stronger filter than either alone, because it confirms the earnings growth is at least partly rooted in genuine business expansion rather than purely capital allocation or one-off effects.
Common mistakes when screening by EPS growth
Treating all EPS growth as equally good news: Margin-driven EPS growth, buyback-driven EPS growth, and one-off-driven EPS growth are three very different situations that look identical in a single headline number.
Ignoring share count trend entirely: A screener showing EPS growth without also showing shares outstanding trend hides one of the three main drivers of the metric. Always check whether the share count has meaningfully changed.
Using a single year of EPS growth as the primary filter: As with revenue growth, a single strong year can reflect a one-off item rather than sustained improvement. Multi-year EPS growth trends are more reliable than any single-period figure.
Ignoring dilution risk: The reverse of the buyback effect — companies issuing new shares (secondary offerings, convertible debt conversion, heavy stock-based compensation) can show EPS growth below net income growth, or even negative EPS growth despite growing net income. This is a real cost to existing shareholders that a pure net-income-growth screen would miss entirely.
Bottom line
EPS growth and revenue growth measure related but genuinely different things, and treating them as interchangeable "growth" signals misses the story behind the number. EPS growth can come from margin expansion (the highest-quality driver), share buybacks (legitimate but different from operating improvement), or one-off items (not representative of ongoing earnings power at all). Screening EPS growth alongside revenue growth and operating margin trend — rather than on its own — lets you tell which of these is actually driving the headline figure.
Frequently asked questions
What's the difference between EPS growth and revenue growth?
Revenue growth measures how fast the top line is expanding — more sales, more customers, more volume. EPS growth measures how fast earnings per share are growing, which incorporates revenue growth plus margin trend plus capital allocation decisions like share buybacks or dilution. The two can diverge significantly, and the gap between them is informative about what's actually driving a company's growth.
Can EPS grow faster than revenue in a good way?
Yes — if operating margin is expanding, net income grows faster than revenue, and EPS grows even faster still if the company is also reducing its share count through buybacks. This is generally a positive combination, reflecting genuine operating leverage plus disciplined capital return, as long as it's confirmed against the margin trend rather than assumed from the EPS figure alone.
Is EPS growth driven by buybacks a bad sign?
Not necessarily. Reducing share count through buybacks is a legitimate way to return capital to shareholders and can be a rational choice when a company has excess cash and limited reinvestment opportunities. It's a different signal than margin-driven or revenue-driven EPS growth, though — worth distinguishing rather than treating all EPS growth as equivalent evidence of operational improvement.
How can I tell if EPS growth came from a one-off item?
Check whether the EPS growth rate is larger than what the revenue growth and margin trend can reasonably explain, and review the income statement for unusual gains — asset sales, litigation settlements, tax benefits — in the relevant period. A single quarter or year of unusually high EPS growth relative to the company's own historical pattern is worth this extra check before treating it as representative.
