SanDisk Is Up 509% YTD After a 251% Revenue Beat - Is the Pullback to $1,382 a Buying Opportunity?

TradingKey - SanDisk (SNDK) up 509% YTD after Q3 FY2026 revenue of $5.95B (+251% YoY), $23.41 EPS vs $12–14 guidance. Q4 guided $7.75–8.25B. Pullback to $1,382 trendline support. Target $1,455–$1,597.

Shares of SanDisk Corporation (NASDAQ: SNDK) are up more than 509% year-to-date in 2026 as of today, after it reported one of the biggest earnings surprises of recent years in the semiconductor sector on April 30. Q3 FY2026 revenue of $5.95 billion, which grew 251% year-over-year and was $1.15 billion above the top of guidance of $4.4 to $4.8 billion, included non-GAAP EPS of $23.41, easily exceeding guidance of $12 to $14 per share.

The stock, which recently tagged an all-time high in the vicinity of $1,455 after touching the top of the channel, has since pulled back to $1,382.89 and is currently in a retest of the ascending black trendline from the April lows. The RSI indicator is neutral with positive divergence on the pullback. Is this a high-conviction dip in a NAND supercycle, or is the stock too far ahead of itself?

SanDisk Q3 FY2026 Earnings Report Is Behind the 509% YTD Rally

The April 30, 2026 quarterly report was the catalyst for SNDK to be reprioritized from a cyclical memory semiconductor company into a critical AI infrastructure component.

In the 2H 2026 reporting period, SNDK reported Q3 revenue of $5.95 billion, 251% year-over-year and 97% quarter-over-quarter growth, while beating top-end guidance by $1.15 billion. This outperformance was led by an intentional move to higher-valued end-markets and NAND pricing that increased as the big three NAND manufacturers reduced supply multiple years ago, while AI data center demands outstripped supply.

Q3 non-GAAP gross margin came in at 78.4%, up from 51.1% the prior quarter and above the 65-67% range forecast, with GAAP earnings of $3.615 billion, or $23.03 diluted shares.

What separates SNDK from a typical NAND commodity supercycle story is the segment breakdown, with Data Center sales jumping 645% year-over-year to $1.47 billion to lead gains, as AI data center build-outs have driven up demand for TLC SSDs, while Edge sales, which include smartphone and PC NAND, increased 295% year-over-year to $3.7 billion after years of under-investment in inventory. Consumer segment sales increased a more modest 44% to $820 million.

CEO David Goeckeler in a post-earnings call, said, “This quarter marks a fundamental inflection point for SanDisk. We have shifted to a higher-valued, multi-year revenue model with our core customers, where we have multi-year commitments, both financially and product-wise.”

For FY Q4, SNDK guidance has been upgraded to revenue of $7.75 to $8.25 billion and non-GAAP earnings of $30 to $33 per share, a significant beat from the previous quarter of $4.4 to $4.8 billion in guidance.

SNDK Q4 earnings guidance is a quarter-over-quarter increase versus Q3 guidance with a midpoint of $8 billion in revenue, rather than deceleration. The $42 billion backlog of multi-year contracts discussed in analyst calls is what differentiates SNDK from a commodity play. SNDK now has the ability to convert its spot-market NAND sales into a much deeper and wider backlog of multi-year, locked-in, and higher-gross-margin revenue contracts.

SNDK Technical Analysis, Trending at $1,324 to $1,382 After Retest Rejection of Channel Top

On the SNDK 2H NASDAQ chart, the stock has retested the steep, black, ascending trendline from the April lows of $1,043 after touching $1,455 to reach the top of the channel.

The stock is sitting at $1,382.89, a retest at the MA dynamic red support line of $1,324 to $1,382, with no breakdown structure, such as a triangle breakdown or engulfing, only a bullish flag retest of rising channel boundaries, higher lows, and an RSI-like indicator of 47 to 54 (neutral) that shows positive divergence on the pullback.

Resistance lies ahead at $1,400 to $1,455, then $1,597 as we head higher in a higher-low bullish flag consolidation. Support for the stock lies in the $1,324 to $1,293 range.

Trade Setup 

Entry: Long above $1,390 as trendline support at $1,324 to $1,382 remains intact with RSI positive divergence.

Target 1: $1,455 Target 2: $1,597 

Stop Loss: $1,324, below trendline on daily close as SNDK could see further support in the $1,324 to $1,293 range.

What’s Driving Sandisk’s Surge This Year?

SNDK has rallied more than 509% in 2026 on the back of both a NAND memory market cycle peak and a business model transformation. Q3 FY26 revenue of $5.95B grew +251% Y/Y and $1.15B to the high end of FY26Q3 guidance. Non-GAAP EPS of $23.41 crushed $12-$14 FY26Q3 guidance. Data Centre revenue grew +645% driven by AI-SSD growth. CEO David Goeckeler has transformed SanDisk from a spot market sales model to multi-year customer contracts and $42B backlog to generate revenue visibility that the market is valuing as a software business model and not commodity memory maker.

What Was Sandisk Q3 Fy26 Earnings and Q4 Guidance?

SanDisk FY2026 Q3 results include:

• Revenue $5.95B (+251% YoY, +97% QoQ) vs. $4.8B guidance
• Non-GAAP gross margin of 78.4% vs. 65%-67% guidance
• Non-GAAP EPS $23.41 vs. $12-$14 FY26 guidance
• Data Centre $1.47B (+645% YoY), Edge $3.7B (+295% YoY), Consumer $0.82B (+44% YoY)
• FY26 Q4 guidance of $7.75-$8.25B revenue, and $30-$33 non-GAAP EPS (continuing the sequential ramp).

The balance sheet is debt-free and the company has an active buyback program.

Is the Sandisk Stock Pullback to $1,382 a Buy?

Technical Setup: Positive. Price is re-testing the ascending trendline established from April lows and with RSI neutral with bullish divergence in the pullback, suggesting there are no buyers that can step in and push it lower and with no evidence it is breaking the uptrend structure and retesting higher lows. If buying at $1,382, a target would be $1,455 and $1,597 if price continues in the direction of the uptrend line (long above $1,390). A trade would be below the recent swing low at $1,324.

Fundamental Setup: Positive. FY2026 Q4 guidance of $7.75-8.25B in revenue, $30-33 EPS, a contract backlog of $42B and non-GAAP gross margins of 78.4% create a very tangible fundamental basis to the bull case on SanDisk. Risks to this include NAND pricing turning lower if supply catches up demand faster than the company expects, and if AI data centres slow their spending.

Bottom Line

SanDisk 509% year-to-date rally is not a meme trade. It was built on a Q3 revenue beat to $5.95B against the $4.8B company-guided, a non-GAAP gross margin of 78.4% and a data centre business line growing at 645% year-over-year. Guidance for FY26Q4 is $8B in revenue. The $42B contract backlog is the basis for arguing SanDisk is changing its business model and not simply riding to the top of the NAND cycle. SAN at $1,382 is trading into support of the ascending trendline and with bullish divergence in the RSI. A buy trade above $1,390 targets $1,455 and $1,597. A trade below $1,324 negates the bull case on SanDisk. SanDisk’s price trend and guidance for FY26Q4 and any information related to the backlog conversion are the fundamental monitors to watch.
