Sandisk reported fiscal fourth-quarter and full-year 2026 results on Wednesday, August 5, 2026, and the official release turned the story into a real live-results phase for options traders. The company said fiscal fourth-quarter revenue reached USD 8.965 billion, up 51% sequentially and 372% year over year, while non-GAAP diluted EPS reached USD 39.25 and GAAP diluted EPS reached USD 43.97. Management also guided to fiscal first-quarter 2027 revenue of USD 10.3 billion to USD 10.8 billion and non-GAAP diluted EPS of USD 44.00 to USD 46.00.
Those facts matter because SNDK is no longer being priced as a generic memory read-through or a leftover separation story. The useful options question now is whether extraordinary pricing, datacenter demand, and long-term supply agreements can keep supporting premium after the market has already seen a record quarter and another aggressive guide.

What Sandisk actually reported
The most important confirmed facts from Sandisk’s August 5, 2026 results materials were:
- Fiscal fourth-quarter revenue was USD 8.965 billion, up 51% sequentially and 372% year over year.
- GAAP gross margin was 84.6% and non-GAAP gross margin was 84.6%.
- GAAP diluted EPS was USD 43.97 and non-GAAP diluted EPS was USD 39.25.
- Fiscal year 2026 revenue was USD 20.248 billion, up 175% year over year.
- Datacenter revenue was USD 2.977 billion in fiscal Q4 2026, up 103% sequentially, and USD 5.153 billion for fiscal 2026, up 437% year over year.
- Sandisk said sequential revenue growth came about one-third from higher volumes and two-thirds from higher pricing.
- Since announcing five New Business Model agreements at the prior earnings call, the company signed five additional agreements, bringing the current total to ten.
- Sandisk approved an additional USD 14 billion buyback program, bringing total remaining repurchase authorization to USD 15.5 billion.
- Management guided to fiscal Q1 2027 revenue of USD 10.3 billion to USD 10.8 billion, non-GAAP gross margin of 83.0% to 85.0%, and non-GAAP diluted EPS of USD 44.00 to USD 46.00.
- Sandisk said it completed its separation from Western Digital on February 21, 2025, making fiscal 2026 the first full-year result set for the standalone company.
Those details matter because they frame the live post-earnings debate correctly. Traders are not just looking at a company that beat a quarter. They are looking at a standalone memory company that is trying to prove its datacenter mix, contract structure, and capital-allocation model can hold up after an unusually strong cycle move.
Why this is a distinct event phase
This is not the same lesson as the site’s older Apple memory-cost read-through or the June 2026 Western Digital debt-exchange article.
The reason is practical:
- The Apple coverage was a customer-side pricing and supplier read-through story.
- The June Western Digital article was a balance-sheet, dilution, and dividend-mechanics story.
- Sandisk’s August 5 release is a live-results story about standalone flash demand, datacenter mix, New Business Model contracts, and how much of a record print can persist into the next guide.
That changes the options-reader lesson in a meaningful way. Traders are no longer asking whether memory pricing is improving in theory. They are asking whether Sandisk’s current earnings power and forward contract structure justify a different volatility and valuation regime after the event.
Why It Matters For Options Traders
1. Datacenter has become the center of the story
Sandisk reported datacenter revenue of USD 2.977 billion in fiscal Q4 2026 and USD 5.153 billion for the full year. That matters because the company is no longer leaning on a broad consumer-storage narrative alone. The release explicitly showed datacenter as the fastest-growing end market and a major growth pillar.
For options traders, that matters because the post-earnings debate shifts from general memory cyclicality toward AI infrastructure exposure, hyperscale demand durability, and whether datacenter mix can keep offsetting volatility in other end markets.
2. Pricing was strong, but traders still need to separate durable demand from cycle intensity
Sandisk said about two-thirds of the quarter’s sequential revenue growth came from higher pricing and about one-third from higher volumes. That is a powerful combination, but it also means the market has to judge how much of current profitability is structural and how much still depends on a favorable pricing environment.
For options traders, that distinction matters more than the headline beat alone. A stock can report record margins and still face a harder premium reset if investors doubt how long the pricing tailwind can stay this strong.
3. New Business Model agreements make the setup more strategic, not risk-free
The company now says it has ten New Business Model agreements and described fixed and variable pricing structures, financial guarantees, and longer-duration commitments. That gives the market a cleaner framework for thinking about demand visibility than a purely spot-driven memory story.
But that does not eliminate risk. For options traders, these agreements raise a more nuanced question: do they reduce earnings uncertainty enough to compress future event premium, or do they simply move the debate toward customer concentration, execution, and whether contracted economics can stay attractive if the cycle cools?
4. The guide was strong enough to keep expectations demanding
Management guided to fiscal Q1 2027 revenue of USD 10.3 billion to USD 10.8 billion and non-GAAP diluted EPS of USD 44.00 to USD 46.00. That matters because the company did not try to protect the quarter with a cautious forward frame. It gave the market another large number to underwrite.
For options traders, that matters because very strong guidance can support a bullish operating narrative while also making the next expectations bar even harder. After a large live beat, the premium debate often becomes less about what just happened and more about how much flawless execution is now implied.
5. Capital allocation adds support, but it does not settle direction
Sandisk expanded its buyback authorization and now has USD 15.5 billion remaining. That is meaningful because it signals confidence in cash-generation durability and gives the company flexibility while the market recalibrates the standalone equity story.
For options traders, the useful takeaway is that repurchases can support the narrative, but they do not remove cycle risk, valuation risk, or post-earnings implied-volatility compression. A bigger buyback is an input into the debate, not a guaranteed directional signal.
Common misunderstandings and caveats
A record quarter means the stock must keep rising
No. The official results were exceptionally strong, but options outcomes still depend on what was already priced into expectations, how implied volatility resets after earnings, and whether traders believe the guide is durable.
Datacenter strength means Sandisk is no longer cyclical
No. Datacenter is now the main growth pillar, but Sandisk still operates inside a semiconductor memory market with pricing, supply, demand, and customer-mix risk.
New Business Model agreements remove uncertainty
No. They may improve visibility and floor economics, but they also shift attention toward contract execution, customer concentration, guarantee structure, and how much flexibility remains if the market changes.
Options pricing reveals where SNDK has to trade next
No. Options pricing reflects uncertainty, hedging demand, time to the next catalyst, and how traders think about the earnings path. It does not provide a clean directional forecast.
Bottom line
Sandisk’s Wednesday, August 5, 2026 live print gave options traders a much more specific post-earnings framework. Fiscal fourth-quarter revenue reached USD 8.965 billion, non-GAAP diluted EPS reached USD 39.25, datacenter revenue reached USD 2.977 billion, the company expanded its total remaining buyback authorization to USD 15.5 billion, and management guided to fiscal Q1 2027 revenue of USD 10.3 billion to USD 10.8 billion with non-GAAP diluted EPS of USD 44.00 to USD 46.00.
For options traders, the useful takeaway is not simply that Sandisk posted a huge quarter. It is that the company is now asking the market to price a different kind of memory story: one built on datacenter flash demand, long-term supply agreements, and a stronger standalone capital-allocation case. The next SNDK premium reset depends on whether traders treat those signals as the start of a more durable earnings-power regime or as the peak of a very favorable cycle. This is not financial advice.
