Approach 1: EnerSys Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model estimates EnerSys's future cash flows over time and discounts them back to today’s dollars, providing investors with an indication of the company’s intrinsic value based on realistic expectations of its future performance.

For EnerSys, the current Free Cash Flow is $329.7 million, measured over the last twelve months. Analysts estimate the company’s annual Free Cash Flow will be $261.9 million by March 2027, with projections extending further and the model forecasting approximately $140.8 million in annual Free Cash Flow by 2035. Estimates beyond five years are projections based on logical trends, as most analysts provide forecasts only up to five years out.

Using these cash flows, the DCF model calculates an intrinsic value per share of $58.23. Currently, the stock trades well above this estimate, making it about 145.3% overvalued based on this approach. This significant premium may indicate that the market is factoring in strong future growth or other favorable developments that may not be reflected in conservative cash flow projections.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests EnerSys may be overvalued by 145.3%. Discover 922 undervalued stocks or create your own screener to find better value opportunities.

Approach 2: EnerSys Price vs Earnings

The Price-to-Earnings (PE) ratio is an essential metric for valuing profitable companies like EnerSys because it connects what investors are willing to pay for a company's earnings. A reasonable or "fair" PE ratio is shaped by expectations around growth and risk, with higher expected growth or lower risk often justifying a higher multiple.

Currently, EnerSys trades at a PE ratio of 15.6x. When compared to the electrical industry average of 30.8x and the average of similar peers at 35.5x, EnerSys appears to be priced more conservatively, suggesting lower market expectations or potentially lower risk. However, these benchmarks may not always capture the nuances of each individual company.

This is where Simply Wall St's "Fair Ratio" becomes valuable. The Fair Ratio of 24.6x for EnerSys is calculated by weighing factors beyond simple industry comparisons, such as projected earnings growth, risk profile, profit margin, and the company’s size. By relying on a tailored Fair Ratio, investors get a more holistic and arguably more precise assessment of intrinsic value.

Comparing the Fair Ratio (24.6x) to EnerSys's current PE (15.6x) reveals that the stock trades at a considerable discount. This suggests EnerSys is undervalued relative to what would typically be expected, presenting an opportunity for investors seeking value.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your EnerSys Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let's introduce you to Narratives. Narratives are a simple but powerful approach that lets you tell your own story behind EnerSys's numbers by combining your perspective on future revenue, earnings, and margins with a fair value estimate.

Unlike static models, a Narrative connects the dots from a company's story through to a detailed financial forecast, then translates that into a fair value per share. Narratives are easy to access on Simply Wall St's Community page, where millions of investors share their real-time outlooks; you can explore or create your own to reflect your unique view on EnerSys and instantly see what it means for the stock's valuation.

Dynamic updates automatically reflect new news, earnings releases, or other crucial information. For example, some investors might have an optimistic Narrative with a fair value of $144 based on robust margin expansion and a strong outlook for digital infrastructure. Others might take a more cautious view, highlighting risks from slow organic growth or delayed projects, resulting in a much lower fair value.
