What is earnings power value?
- EPV values a company based on its current earnings, not future growth.
- It uses normalized earnings and cost of capital to get a number you can compare to market cap.
- Developed by Bruce Greenwald, it's a tool for finding undervalued stocks.
- But it assumes constant earnings, so it works best for stable businesses.
What is earnings power value?
Earnings power value (EPV) divides a company's normalized earnings by its cost of capital to show what a steady business is worth today. It ignores future growth and uses only current earnings. EPV builds on Bruce Greenwald's idea that steady earning power drives value, capturing a going concern's earning power.
The idea traces to Benjamin Graham, who argued in 1937 that a business's true worth lies in its sustained earning power. Bruce Greenwald later formalized it at Columbia, giving value investors a disciplined stand-in for volatile forecasts.
How to calculate EPV
The formula is simple: EPV equals normalized earnings divided by cost of capital. The work is building those earnings. Multiply current sales by your average EBIT margin over a full business cycle to get normalized EBIT, then apply your after-tax rate to reach normalized earnings.
Then subtract maintenance capital expenditure, the cash needed just to keep the plant running and output flat. This is not growth spending. It is replacement spend, the repairs and upkeep that hold today's profit in place.
Adjust for excess depreciation too. Book depreciation may sit above what maintenance truly costs, so add back the gap. What remains is a realistic sustainable profit, the earnings you can genuinely expect to repeat.
Divide that number by your cost of capital. The result is EPV, the worth implied by steady earnings alone. Compare it to market capitalization to judge whether the market is paying a fair price for that earning power.
What EPV tells you
You compare EPV to market cap. If EPV is higher, the stock is undervalued; if lower, it's overvalued. EPV focuses on current earning power rather than future promises, so a wide gap between market price and computed value flags a potential opportunity.
How to get EPV equity value
The formula so far prices the operations alone. To reach the full equity value, add excess net assets: surplus cash, marketable securities, and real estate not needed to run the business. Then subtract interest-bearing debt. What remains is EPV equity.
Divide that number by the shares outstanding and you get earnings power value per share. Now you compare it directly to the stock price, not just the total market cap. Value investors watch that per-share gap to spot mispricing at a glance.
Franchise value: the growth premium
When EPV exceeds what the assets cost to replace, the difference is franchise value. That premium comes from pricing power, customer loyalty, or a moat competitors cannot copy. You pay for the asset base plus that premium, and the real question becomes whether the moat lasts.
EPV versus reproduction value
Greenwald pairs EPV with reproduction value, the cost to rebuild the business from scratch. When EPV sits far above it, the market prices in an asset-light franchise. When EPV sits below, something drags on earning power. The two numbers frame the same trade.
ROIC versus cost of capital
EPV leans on one ratio: return on invested capital against cost of capital. A firm that earns more than its capital costs can reinvest and keep creating value. One that earns less destroys value even when profits look healthy. That spread drives the whole framework.
Choose your discount rate with care
The cost of capital drives the whole answer, so pick it deliberately. Many analysts use the weighted average cost of capital, built on beta and the capital asset pricing model. Both carry known flaws, and critics argue those assumptions are weaker than the earnings they discount.
A cleaner route is your own required rate of return. Value investors often set a personal hurdle rate and fold it into the calculation. The formula stays the same; only the discount rate you trust changes.
EPV versus a DCF
EPV is a DCF with growth set to zero. A full model forecasts years of future cash, while EPV prices only what the firm earns today at a steady cost of capital. For a mature, stable company, EPV strips out the guesswork and shows worth without the growth story.
Limitations of EPV
You should know: EPV assumes constant earnings forever. It ignores growth, competition, and market shifts. That makes it best for stable businesses with steady demand, and weakest during sharp industry change. It's a tool, not a crystal ball.
