Approach 1: West Pharmaceutical Services Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates a company’s intrinsic value by projecting its future cash flows and discounting them back to today’s dollars. This method focuses on how much cash the business will generate, adjusting for the time value of money. It can offer a useful reality check versus the current share price.

West Pharmaceutical Services currently generates free cash flow of $336.7 Million. According to analyst forecasts, free cash flow is projected to reach $542 Million by 2028. The next 5 years are based on professional analyst estimates, with future growth extrapolated by Simply Wall St for a complete 10-year outlook.

Based on these projections, the estimated intrinsic value of West Pharmaceutical Services is $173.46 per share, calculated with a 2 Stage Free Cash Flow to Equity model. However, this value is 65.4% lower than the recent share price, which signals that the stock is likely overvalued according to this DCF approach.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests West Pharmaceutical Services may be overvalued by 65.4%. Discover 841 undervalued stocks or create your own screener to find better value opportunities.

Approach 2: West Pharmaceutical Services Price vs Earnings

The Price-to-Earnings (PE) ratio is a time-tested benchmark for evaluating profitable companies, providing a straightforward way to assess how much investors are willing to pay for each dollar of earnings. Since West Pharmaceutical Services generates consistent profits, the PE ratio is a meaningful lens because it anchors valuation directly to earnings power.

Growth expectations and risk profile play a big role in what is considered a “normal” or fair PE ratio for any company. High-growth firms typically command higher PE ratios to reflect anticipated earnings expansion, while elevated risks or volatile markets can lower the appropriate PE ratio.

Currently, West Pharmaceutical Services trades on a PE ratio of 42x, which is higher than both its peer average of 29x and the broader industry average of 38x for Life Sciences. However, Simply Wall St’s proprietary “Fair Ratio,” which tailors the benchmark by factoring in company-specific measures like earnings growth, profit margins, industry, market cap, and risk, suggests a fair PE of 27x for West. This nuanced metric goes beyond simple peer or sector comparisons and offers a more holistic view of what the company should reasonably be valued at given all the data in context.

Comparing the actual PE ratio (42x) to the Fair Ratio (27x), the stock currently appears to be priced above what a balanced, data-driven assessment would suggest.

Result: OVERVALUED
