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

A Discounted Cash Flow, or DCF, model estimates what a business might be worth today by projecting its future cash flows and discounting them back to a present value. It focuses on the cash that could be available to shareholders rather than accounting earnings.

For Advanced Drainage Systems, the model used is a 2 Stage Free Cash Flow to Equity approach, starting from last twelve months free cash flow of about $604.4 million. Analysts provide explicit forecasts through 2027, including projected free cash flow of $553.6 million in the year to March 2027. Beyond that, Simply Wall St extrapolates up to ten years of cash flows, with estimates such as $583.99 million in 2035, all in dollars and discounted back to today.

Aggregating these discounted cash flows produces an estimated intrinsic value of about $111.50 per share. Compared with the recent share price of $134.32, the model implies the stock is roughly 20.5% overvalued on this basis.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Advanced Drainage Systems may be overvalued by 20.5%. Discover 61 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Advanced Drainage Systems Price vs Earnings

For a profitable company, the P/E ratio is a useful way to judge how much you are paying for each dollar of earnings, which tends to matter more to shareholders than revenue or assets alone.

What counts as a “normal” P/E depends on what the market expects for future growth and how risky those earnings appear. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually call for a lower one.

Advanced Drainage Systems currently trades on a P/E of 22.23x, compared with the Building industry average of 20.35x and a peer group average of 41.61x. Simply Wall St’s Fair Ratio for the stock is 29.60x, which is its proprietary view of what the P/E “should” be once earnings growth, profit margins, industry, market cap and risk factors are all considered.

This Fair Ratio aims to be more tailored than simple peer or industry comparisons, because it adjusts for company specific strengths and weaknesses rather than assuming all firms deserve similar valuations.

Since the current P/E of 22.23x is below the Fair Ratio of 29.60x, the shares appear undervalued on this metric.

Result: UNDERVALUED
