Approach 1: Sandisk Discounted Cash Flow (DCF) Analysis

A DCF model takes estimates of a company’s future cash flows and discounts them back to today’s dollars, to see what those future streams might be worth right now.

For Sandisk, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $481.4 million. Analysts provide explicit free cash flow estimates through 2028, with Simply Wall St extrapolating out to 2035. For example, the model includes a projected free cash flow of $3.19b in 2028, with intermediate and later years stepping up from current levels according to the inputs you see in the forecast table.

Discounting those projected cash flows back to today produces an estimated intrinsic value of about $504.99 per share. Compared with the recent share price of $353.56, this implies roughly a 30.0% discount. This indicates that Sandisk is trading below this cash flow based estimate of value.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Sandisk is undervalued by 30.0%. Track this in your watchlist or portfolio, or discover 884 more undervalued stocks based on cash flows.

Approach 2: Sandisk Price vs Sales

For companies where revenue is a key focus, the P/S ratio is a useful yardstick because it compares what the market is paying for each dollar of sales, regardless of current profits. Higher growth expectations or lower perceived risk can justify a higher P/S multiple, while slower expected growth or higher risk usually points to a lower, more conservative range.

Sandisk currently trades on a P/S of 6.66x. That sits above both the broader Tech industry average P/S of 1.56x and the peer group average of 4.31x. This indicates the market is currently assigning a richer sales multiple than these benchmarks. Simply Wall St’s Fair Ratio for Sandisk is 3.57x, which is the P/S level their model suggests based on factors such as earnings growth, industry, profit margin, market cap and risks.

The Fair Ratio offers a more tailored reference point than a simple comparison with peers or the sector because it blends company specific traits, including growth profile, risk level and profitability, with its industry and size. Comparing the 3.57x Fair Ratio with the current 6.66x suggests Sandisk’s shares are pricing in more optimism than the model implies.
