Company life cycles
Where is this company in its life, and what should that change?
Companies age the way people do: a predictable arc from start-up to growth to maturity to decline, usually faster than its managers admit. Aswath Damodaran's corporate life cycle maps that arc onto the numbers a valuation runs on — so the story you pay for matches the age of the company telling it.
Young growth
Mostly promise
Revenue is small and growing fast, the business model is still being proven, and losses are normal because everything earned (and more) goes back into growth.
- Revenue growth
- Very high, off a small base
- Operating margin
- Low or negative today
- Reinvestment
- Heavy — growth is bought
- Payout to shareholders
- None
- Where the value sits
- Almost all in the far future
What to question at this stage: The margin the story assumes at maturity. A young company is valued on the business it might become, so ask what evidence supports that destination.
Put a stage to the test
Open the stock valuation template and type the same 20% growth into a young company and a 40-year-old bank. The young company's value leans almost entirely on the far future; the bank's story strains, because a mature balance sheet can't reinvest fast enough to grow like that.
How to read the result
Technical
Each stage maps to the valuation inputs: young companies get high growth and heavy reinvestment, mature ones stable margins and payout.
Plain English
A company's age tells you which numbers to question. Fast growth forever is the story that most often fails.
Technical
Across the cycle, revenue growth and reinvestment fall while margins and payout rise, and value shifts from the far future into assets already in place.
Plain English
Young companies are mostly promise and old ones mostly track record. The expensive mistake is pricing one like the other.
Technical
The stage disciplines a valuation's story: a mature company priced for a start-up's growth, or a young one valued on today's margins, is a story–age mismatch.
Plain English
Before arguing about a number, ask whether a company of this age could deliver it.
A worked example
Put the same 20% growth into a start-up and a 40-year-old bank in the Stock valuation template and see which story strains. The start-up's value leans on the far future; the bank can't reinvest fast enough to grow like that.
What it can't tell you
- Stages are a lens, not a law. Companies can re-age — or skip straight to decline.
- Stage labels are judgment, not data. Companies don't announce which stage they're in.
- Life-cycle patterns are drawn mostly from US companies, used as a proxy for Singapore ones.
