Approach 1: Tower Semiconductor Discounted Cash Flow (DCF) Analysis

A DCF model estimates what a stock could be worth by projecting the company’s future cash flows and discounting them back to today’s value. In this case, the model used is a 2 Stage Free Cash Flow to Equity approach, based on Tower Semiconductor’s projected cash flows in US$.

The latest twelve month free cash flow is a loss of $73.5 million, so the model leans heavily on future estimates. Analyst and extrapolated forecasts suggest free cash flow turning positive and reaching $4,452.6 million in 2035, with key interim points including $317.5 million in 2027 and $842 million in 2028. Simply Wall St extrapolates beyond the initial analyst horizon to build a 10 year path of cash flows.

Discounting these projected cash flows back to today results in an estimated intrinsic value of $182.34 per share. Compared with the current share price of $210.00, the model implies the stock is about 15.2% overvalued based purely on these cash flow assumptions.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Tower Semiconductor may be overvalued by 15.2%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Tower Semiconductor Price vs Earnings

For profitable companies, the P/E ratio is a useful way to connect what you pay for the stock with the earnings the business is currently generating. It lets you see how many dollars investors are willing to pay today for each dollar of earnings.

What counts as a “normal” P/E depends on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth and lower perceived risk can support a higher P/E, while slower growth or higher risk usually points to a lower P/E being more reasonable.

Tower Semiconductor currently trades on a P/E of 107.38x, compared with a Semiconductor industry average of 59.42x and a peer average of 59.28x. Simply Wall St’s Fair Ratio for Tower Semiconductor is 58.19x. This Fair Ratio is a proprietary estimate of what the P/E might be based on factors such as earnings growth, profit margins, industry, market cap and risk. Because it adjusts for these company specific inputs, it can be more tailored than a simple comparison with peers or the wider industry.

With the current P/E well above the Fair Ratio, Tower Semiconductor looks expensive on this metric.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Tower Semiconductor Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives are introduced here as simple stories you create about Tower Semiconductor that connect your view of its future revenue, earnings and margins to a specific fair value, then compare that fair value with the current price to help decide whether the stock looks attractive or stretched.

On Simply Wall St’s Community page, Narratives let you quickly plug in assumptions rather than build a full model. The platform then links your story to a live forecast and updates it automatically when new data, news or earnings are added.

For Tower Semiconductor today, one investor might build a more cautious Narrative that aligns with a fair value around US$140.00. Another might build an optimistic Narrative closer to US$226.36.

Implied pricing gap vs current US$210.00: about 21.4% above this fair value level

Revenue growth used in this story: 21.16% a year

• Highlights that the consensus view still relies on strong growth in silicon photonics and specialty nodes, but sees the current valuation as demanding relative to those assumptions.
• Points to risks around heavy capital spending, customer concentration and exposure to geopolitical and competitive pressures in specialty foundry markets.
• Bases its view on revenue reaching US$2.8b and earnings of US$732.5m by about April 2029, with the stock on a P/E of 39.8x and a 13.43% discount rate.
