Approach 1: Sandisk Discounted Cash Flow (DCF) Analysis

A DCF model takes estimates of a company’s future cash flows, discounts them back to today using a required return, and sums them to get an estimate of what the business might be worth per share right now.

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 $481.4 million. Analyst and extrapolated estimates then project free cash flow rising to $4.3b by 2035, with interim projections such as $1.9b in 2026, $2.5b in 2027 and $2.8b in 2028, all expressed in US$ terms.

Discounting these projected cash flows back to today gives an estimated intrinsic value of about $416.64 per share. Compared with the recent share price of $409.24, the model suggests Sandisk trades at roughly a 1.8% discount to this DCF estimate, which is a very small gap and well within any reasonable margin of error.

Result: ABOUT RIGHT

Sandisk is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: Sandisk Price vs Sales

For Sandisk, P/S is the preferred yardstick because it focuses on revenue rather than earnings, which can swing around with accounting items or investment cycles. For profitable companies, it gives you a clean view of how much investors are willing to pay for each dollar of sales.

The "right" P/S also depends on what the market expects for growth and how much risk it sees. Higher expected growth or lower perceived risk can justify a higher multiple, while slower growth or higher risk usually calls for a lower one.

Sandisk currently trades on a P/S of 7.71x, compared with a Tech industry average of 1.81x and a peer group average of 4.10x. Simply Wall St’s Fair Ratio for Sandisk is 3.81x, which is a proprietary estimate of what the P/S could be given factors like earnings growth, industry, profit margins, market cap and identified risks. This Fair Ratio is more tailored than a simple peer or industry comparison because it folds those company specific inputs into a single number. On this basis, Sandisk’s current P/S sits well above the Fair Ratio, which points to the shares looking expensive on a sales multiple view.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Sandisk Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, which are simply your story about a company linked directly to numbers like your assumed fair value and your expectations for future revenue, earnings and margins.

A Narrative connects three pieces in one place: what you think is happening with the business, how that story flows into a financial forecast, and what that implies for a fair value per share.

On Simply Wall St, Narratives sit inside the Community page, where millions of investors use them as an easy, accessible tool to compare their Fair Value to the current price and decide whether a stock might belong on their watchlist, be a potential buy, or look ready to trim or exit.

Narratives keep updating as new information arrives, such as company announcements, earnings or news. This means your fair value view does not stay frozen while the world changes.

For Sandisk, for example, one investor might build a Narrative with a very optimistic fair value based on strong revenue and margin assumptions. Another might use more cautious forecasts and arrive at a much lower fair value, and both can see clearly how their story drives the numbers.
