Approach 1: Sandisk Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting the cash the company might generate in the future and discounting those cash flows back to today using a required rate of return.

For Sandisk, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections. The latest twelve month Free Cash Flow is about $4.37b. Analysts provide detailed forecasts for the next few years. Beyond that, Simply Wall St extrapolates the trend, leading to a projected Free Cash Flow of $8.60b in 2030 and a full 10 year path of estimated cash flows in between.

Discounting those projected cash flows back to today results in an estimated intrinsic value of about $876.73 per share. Against the current share price of $1,406.32, this implies the stock is around 60.4% above the DCF estimate, which points to Sandisk trading well above this particular assessment of its cash flow value.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Sandisk may be overvalued by 60.4%. Discover 50 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Sandisk Price vs Earnings

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

What counts as a "normal" P/E depends a lot on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can justify a higher multiple, while slower growth or greater uncertainty usually supports a lower one.

Sandisk is trading on a P/E of 46.21x. That is higher than the broader Tech industry average P/E of 23.82x, yet lower than the peer group average of 63.18x. Simply Wall St also calculates a proprietary “Fair Ratio” for Sandisk of 106.18x, which reflects factors such as earnings growth, industry, profit margins, market cap and company specific risks.

This Fair Ratio is more tailored than a simple comparison with peers or the industry because it adjusts for Sandisk’s own characteristics rather than assuming all companies should trade at similar levels. Since the Fair Ratio of 106.18x is significantly above the current P/E of 46.21x, this framework points to Sandisk trading below its indicated fair multiple.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Sandisk Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so here is Narratives, a simple tool on Simply Wall St’s Community page that lets you connect your view of Sandisk’s business to explicit forecasts for revenue, earnings and margins. These then roll up into a Fair Value that you can compare with the current share price to help decide whether the stock looks attractive or expensive.

A Narrative is essentially your story for the company written in numbers. For example, one investor might lean toward the bearish Fair Value of about US$157.81 based on revenue growth of 16.3% and profit margins reaching 13.8%. Another might lean toward the bullish Fair Value of about US$322.00 using revenue growth of 31.5% and margins at 32.0%. Both views update automatically as fresh data such as news or earnings are reflected in the underlying estimates.
