TTM EPS Growth: Definition, Formula & How UQS Uses It
What Is TTM EPS Growth?
Trailing Twelve-Month Earnings Per Share (EPS) Growth measures how much a company's per-share profit has increased over the most recent twelve-month period compared to the prior twelve months. While revenue growth shows whether the business is getting bigger, EPS growth reveals whether it's getting more profitable for shareholders specifically. EPS growth can exceed revenue growth when a company achieves operating leverage (fixed costs spread over more revenue), improves margins through pricing power or efficiency gains, or reduces its share count through buybacks. Conversely, EPS can lag revenue if the company is investing heavily in growth (increasing expenses), if margins are compressing due to competition, or if share dilution from stock-based compensation offsets earnings improvement. Because EPS is what ultimately drives stock valuations — the P/E ratio is literally price divided by EPS — strong EPS growth tends to be rewarded with multiple expansion, creating a double benefit: higher earnings plus a higher valuation on those earnings. This is the mechanism behind the most powerful stock moves in the market.
How Is TTM EPS Growth Calculated?
EPS_TTM is diluted earnings per share over the most recent four quarters, and EPS_Prior_TTM is the same for the four quarters before that. The absolute value in the denominator handles cases where the prior period's EPS was negative — without it, a company improving from -$1 to +$1 EPS would show a misleading -200% growth. By using absolute value, the same improvement correctly shows +200% growth. Diluted EPS is used rather than basic EPS to account for the potential dilution from stock options, convertible debt, and restricted stock units that could increase the share count. This ensures the growth rate reflects the true per-share economics that investors will experience.
How UQS Score Uses TTM EPS Growth
TTM EPS Growth carries a 15% weight in the Growth pillar, making it a supporting metric alongside the more heavily weighted forward estimates and TTM revenue growth. The Growth pillar uses the weightedAvg method, where each metric has a fixed percentage that redistributes if null. EPS growth is scored against absolute thresholds: growth above 30% scores very well, above 15% is solid, and declining EPS creates significant scoring headwinds. Because EPS can be volatile (one-time charges, tax windfalls, buyback effects), UQS weights it less than revenue growth and forward estimates, which tend to be more stable signals. However, when EPS growth substantially exceeds revenue growth, it's a positive signal of improving operational efficiency that the Quality pillar's margin metrics will also capture.
Real-World Example
NVIDIA (NVDA) reported TTM EPS growth of 147%, meaning its per-share profits nearly 2.5 times the prior year's level. This exceeded even NVDA's remarkable 114% revenue growth, indicating significant operating leverage — as revenue scaled, NVIDIA's already-high margins expanded further, compounding the earnings effect. This kind of EPS growth outpacing revenue growth is the hallmark of a business with enormous pricing power and high fixed-cost leverage. The combination propelled NVDA to one of the highest growth pillar scores in the UQS universe. Not all EPS growth is created equal, however: a company that grew EPS by 50% through aggressive share buybacks while revenue was flat would score well on this specific metric but poorly on the revenue growth components, resulting in a balanced Growth pillar score that reflects the reality.
Frequently Asked Questions
What is a good EPS growth rate?
For large-cap companies, 10-20% annual EPS growth is considered strong, and above 25% is exceptional. Small and mid-cap companies in high-growth industries can sustain 25-50%+ EPS growth during expansion phases. Peter Lynch famously looked for companies with EPS growth rates between 20-50%, considering slower growth boring and faster growth unsustainable. The sustainability of EPS growth matters more than the absolute number: a company growing EPS at 15% annually for a decade creates more value than one growing at 100% for one year followed by stagnation. UQS captures this distinction through the CAGR metric in the growth pillar.
What is the difference between trailing and forward EPS?
Trailing EPS is the actual, reported earnings per share over the past twelve months — it's historical fact. Forward EPS is the analyst consensus estimate of what EPS will be over the next twelve months — it's an educated prediction. Trailing EPS tells you what the company has actually earned, while forward EPS reflects what the market expects. Stock prices are primarily driven by forward expectations rather than trailing results, which is why forward EPS estimates tend to be more correlated with stock price movements. When analysts raise forward EPS estimates, stocks tend to rise even before the earnings materialize, and vice versa.
