Approach 1: Sandisk Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model projects a company’s future cash flows and then discounts them back to today’s dollars to estimate what the business might be worth right now.

For Sandisk, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $1.41b. Analyst and extrapolated projections suggest free cash flow could reach around $21.01b in 2035, with interim years such as 2026 and 2028 modeled at $5.09b and $11.98b respectively. Simply Wall St uses analyst estimates where available and then extends those forecasts out to ten years using its own assumptions.

Pulling all these projected cash flows together and discounting them back results in an estimated intrinsic value of about $1,992.15 per share. Compared with the current share price of $603.17, this DCF output indicates an undervaluation of 69.7% under these assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Sandisk is undervalued by 69.7%. Track this in your watchlist or portfolio, or discover 61 more high quality undervalued stocks.

Approach 2: Sandisk Price vs Sales

For companies where revenue is a key driver and profits may not fully reflect the business yet, the P/S ratio is often a useful way to think about valuation. It links what you pay for each share to the sales the company is already generating.

Higher growth expectations or lower perceived risk can justify a higher P/S ratio, while slower growth or higher risk typically point to a lower, more conservative multiple. That is why simply comparing one number in isolation rarely tells the full story.

Sandisk currently trades on a P/S ratio of 9.97x. That is well above the Tech industry average of 1.48x and also higher than the peer group average of 4.75x. Simply Wall St’s Fair Ratio for Sandisk is 10.39x, which is its view of what a “normal” P/S might look like given factors such as the company’s growth profile, profit margins, risk characteristics, industry and market cap. This Fair Ratio is designed to be more tailored than a simple comparison with peers or the broader industry because it adjusts for those company specific features.

The current P/S of 9.97x sits slightly below the Fair Ratio of 10.39x, which points to the shares being modestly undervalued on this measure.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Sandisk Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St give you a clear story behind your Sandisk numbers by linking your view of its business drivers to a set of revenue, earnings and margin forecasts. These are turned into a Fair Value you can compare with the current price, updating automatically as new news or earnings arrive. This allows very different views, such as a more cautious Fair Value near US$157.81 and a more optimistic view around US$322.00 or even US$778.20, to sit side by side, so you can quickly see which story you agree with and what that implies for your own buy or sell decisions on the Community page used by millions of investors.

For Sandisk, however, we will make it really easy for you with previews of two leading Sandisk Narratives:

Fair value: US$778.20

Current price vs this fair value: about 22.5% below the narrative fair value

Revenue growth assumption: 71.08%

• Frames Sandisk as a pure play NAND leader following its spin off from Western Digital, with the story centred on AI driven demand for high speed flash storage.
• Highlights BiCS8 3D NAND, higher margins and index inclusion as key supports for earnings power and valuation, with a fair value anchor around US$778.20.
• Flags risks such as memory cycle concerns, reliance on the Kioxia joint venture and residual Western Digital ownership that could still affect the share price.

Fair value: US$157.81

Current price vs this fair value: about 282.3% above the narrative fair value

Revenue growth assumption: 16.32%

• Argues that expectations for AI related storage demand and data center SSD uptake could prove too optimistic, especially if hyperscalers slow spending or push harder on long term pricing.
• Uses analyst assumptions that revenue grows at 16.32% a year with margins improving, but still concludes that the implied P/E and share count trends leave the current price well ahead of this fair value.
• Notes that while Sandisk has moved to net cash and is generating free cash flow, this view sees the share price as embedding much stronger outcomes than the bearish fair value of US$157.81 implies.

Your own stance likely sits somewhere between these two stories. To see how other investors are joining the dots on growth, risks and valuation, check the Community Narratives for Sandisk and see where your view lines up with the herd and where it differs.
