Approach 1: Advanced Drainage Systems Discounted Cash Flow (DCF) analysis

A discounted cash flow (DCF) model estimates a company's current value by projecting its future cash flows and then discounting them to their current value. This approach provides an estimate of what investors could reasonably pay for the company now, given its future earnings power.

For Advanced Drainage Systems, the most recently reported free cash flow is $536 million. Cash flow is forecast to remain strong over the next decade, with analysts providing annual estimates for the first five years and subsequent years extrapolated by Simply Wall St. Free cash flow is expected to be $517.2 million by 2027 and $581.7 million by 2035.

The DCF model calculates an intrinsic value of $108.76 per share. A comparison to the current market price shows an implied discount of -41.1%, meaning the stock is trading well above its forecast fair value. Using this approach, Advanced Drainage Systems shares appear significantly overvalued at today's prices.

Result: OVERRATED

Our discounted cash flow (DCF) analysis suggests that Advanced Drainage Systems may be overvalued by 41.1%. Discover 928 undervalued stocks or create your own screener to find better opportunities.

Approach 2: Price-performance ratio of Advanced Drainage Systems

For profitable companies, the price-to-earnings ratio (P/E) is a widely used metric for assessing valuation because it directly relates a company's current price to its earning power. This makes the P/E ratio particularly suitable for assessing established companies such as Advanced Drainage Systems that continually generate profits.

The interpretation of what constitutes a “fair” PE ratio depends on factors such as expected growth rates and risk. In general, companies that have higher earnings growth or lower perceived risks can justify a premium or higher P/E multiple compared to slower-growing or riskier companies in the same sector.

Looking at the numbers, Advanced Drainage Systems trades at a P/E ratio of 26x, which is well above the construction industry average of 19x and the industry average of 18x. On the face of it, this suggests that the stock is valued at a premium compared to both its direct peers and the broader sector.

However, Simply Wall St introduces the “Fair Ratio”, which reflects a more nuanced P/E ratio based on the company's own growth prospects, profitability, risk profile, market capitalization and industry context. Unlike simple peer or industry comparisons, the Fair Ratio represents a tailored benchmark that answers whether a premium or discount is actually warranted for that specific company.

In this case, Advanced Drainage Systems' fair ratio is 26x, which is almost exactly the current PE multiple. This orientation indicates that the market is valuing the company appropriately given its prospects, financial strength and risks.
