Approach 1: Axcelis Technologies Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a business could be worth by projecting its future cash flows and then discounting those back to today using a required rate of return. It is essentially asking what Axcelis Technologies' future cash generation is worth in today's dollars.

For Axcelis, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $105.9 million, with analysts providing a future free cash flow estimate of $231 million for 2023. Beyond the usual analyst horizon, Simply Wall St extrapolates cash flows out to 2035, with annual projections such as $96.8 million in 2026 and $100.1 million in 2035, each discounted back to reflect time and risk.

Aggregating these discounted projections gives an estimated intrinsic value of about $35.03 per share. Compared with the recent share price of US$85.74, the DCF output suggests the stock is around 144.8% above this model's fair value estimate. This indicates a comparatively rich valuation based on these assumptions.

Result: OVERVALUED

Approach 2: Axcelis Technologies Price vs Earnings

For profitable companies, the P/E ratio is a useful way to see how much you are paying for each dollar of earnings. It reflects what the market is willing to pay today based on what it expects from future earnings and how risky those earnings appear to be.

Higher growth expectations and lower perceived risk usually support a higher P/E, while slower growth or higher risk tend to justify a lower P/E. Axcelis Technologies currently trades on a P/E of 21.91x. That sits below the broader Semiconductor industry average P/E of about 43.64x and also below the peer average of 59.65x. This may suggest the market is assigning it a lower valuation than many comparables.

Simply Wall St’s Fair Ratio concept goes a step further. It estimates what a company’s P/E might be, given factors such as earnings growth, profit margins, industry, market cap and key risks. For Axcelis, this Fair Ratio is 18.38x, which is below the current 21.91x. Because Fair Ratio adjusts for company specific fundamentals, it can be more informative than simply lining the stock up against industry or peer averages.

Upgrade Your Decision Making: Choose your Axcelis Technologies Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives are introduced as a simple way for you to write the story behind your numbers for Axcelis Technologies, linking what you believe about its products, markets, risks and opportunities to a financial forecast, a fair value, and then a clear comparison to the current share price. All of this is done within an easy tool on Simply Wall St’s Community page that is updated when new news or earnings land. One investor might build a Narrative that leans into Axcelis’s leadership in high energy ion implantation, silicon carbide adoption and recurring service revenue and arrive at a higher fair value such as the US$92 central estimate. Another might focus more on China exposure, analyst assumptions for revenue to decrease 2.3% each year, margin compression to 8.0% and earnings of US$66.7 million by 2028 and land closer to or even below the US$85.5 analyst target. This gives you two very different but structured views on whether today’s price of US$75.72 looks attractive or stretched.
