    Executive summary

    Sandisk Q4 FY25 — Strong Revenue & EPS Beat Driven by Bit Shipments and ASPs

    Sandisk delivered a strong Q4 FY25, surpassing revenue and EPS guidance, driven by robust bit shipments and ASPs, particularly in data center and client markets. The company is navigating a pivotal BiCS 8 nodal transition, which, while capital-intensive initially, is expected to drive significant financial improvement in FY26 amidst a favorable supply-demand environment and strategic pricing actions.

    Highlights

    5

    • Revenue of $1.9 billion, up 12% QoQ, exceeding guidance of $1.75 billion-$1.85 billion.

    • Non-GAAP EPS of $0.29, exceeding guidance of a loss of $0.10 to a profit of $0.15.

    • Inventory reduced from 150 to 135 days, indicating improved supply-demand balance.

    • Net debt reduced to $368 million, with $195 million in Term Loan B prepayments, progressing towards net cash positive.

    • Data center demand remains strong, representing over 12% of total bits shipped, driven by AI workloads.

    Concerns

    4

    • BiCS 8 nodal transition brings above-average capital intensity and below-average cost reductions in the near term.

    • Non-GAAP gross margin for Q4 FY25 included $51 million in underutilization charges and $42 million in fab start-up costs.

    • Q1 FY26 non-GAAP gross margin guidance includes $10 million-$15 million in underutilization charges and approximately $60 million in fab start-up costs.

    • Non-GAAP operating expenses for Q1 FY26 are higher due to an additional week and one-time costs for qualification samples, totaling $20 million-$25 million.

    Period spend: $343 million
    Funding: $109 million from depreciation (COGS); $262 million from external sources (subsidies and JV equipment leasing)
    Start: Q4 FY25

    Benefit: Industry-leading node for performance, density, and power efficiency; 40-50% of bits by end of FY26.

    The nodal transition brings above-average capital intensity and below-average cost reductions in the near term, but is expected to drive significant financial improvement with expanding margins and cash generation in FY26.

    Risks & headwinds

    4
    BiCS 8 nodal transitionNear term (FY26)

    Above-average capital intensity and below-average cost reductions in the near term.

    Mitigation: Expected to be a year of significant financial improvement with expanding margins and cash generation as macro headwinds subside and demand/supply remain favorable.

    Fab start-up costsQ4 FY25, Q1 FY26, expected to reduce significantly in Q2 and Q3 FY26.

    $42 million in Q4 FY25, $60 million in Q1 FY26.

    Mitigation: These costs are episodic and will go away as the transition completes, leading to minimal impacts thereafter.

    Underutilization chargesQ4 FY25, Q1 FY26, expected to be close to zero thereafter.

    $51 million in Q4 FY25, $10 million-$15 million in Q1 FY26.

    Mitigation: Inventory levels are coming down, some products are on allocation, and an undersupply situation is observed in the market.

    Tariffs on semisOngoing

    Not quantified, but mentioned as a dynamic part of the equation.

    Mitigation: Staying very close to the situation, engaging in conversations with relevant parties, and confident in ability to navigate with global footprint.

    Why it matters

    Indicates the pace of nodal transition and realization of cost efficiencies, which are key to margin expansion.

    Fiscal year '26 marks a pivotal transition as BiCS 8 becomes our prominent node. We've made strong progress ramping up this industry-leading node into high-volume manufacturing... we will be somewhere between 40% and 50% by the end of fiscal year '26.

    Q&A highlights

    6

    Seeking more depth on gross margin, specifically underutilization, cost downs, and mix, given the Q1 FY26 guide was less than expectations.

    Luis Visoso explained that underutilization charges are decreasing ($51M in Q4 to $10M-$15M in Q1), but start-up costs for BiCS 8 are increasing ($42M in Q4 to $60M in Q1). These start-up costs are expected to significantly decline in Q2 and Q3. The cost curve normalization from BiCS 8 will be seen as its mix increases from 7% (Q4 FY25) to 40-50% (end of FY26).

    “Really, the biggest impact on gross margin this quarter is start-up costs, right? Start-up costs are somewhere around $60 million, which continued to impact us in the quarter. If you look at both together, underutilization and start-up costs for the quarter, it's about 300 basis points. And the good news is they will go away, right?”

    Detailed Narrative

    01

    BiCS 8 Transition and Cost Structure

    The company is undergoing a pivotal transition to BiCS 8, which accounted for 7% of bits in Q4 FY25 and is projected to reach 40-50% by the end of FY26. This transition, while initially capital-intensive and leading to lower near-term cost reductions, is expected to drive significant financial improvement, expanding margins, and cash generation in FY26 as macro headwinds🌐 subside. Start-up costs associated with BiCS 8 are expected to significantly decline in fiscal Q2 and Q3, becoming minimal thereafter, turning current headwinds into tailwinds.

    02

    Data Center Expansion and AI Focus

    Data center demand remains robust, driven by hyperscaler investments, with this segment representing over 12% of total bits shipped in Q4. Sandisk is advancing in enterprise SSDs for AI data lakes and compute-heavy applications, notably with a 256-terabyte NVMe enterprise SSD powered by UltraQLC. The company is pursuing qualifications with key hyperscalers, including a second major one and customers using NVIDIA GB300, with qualifications expected to ramp through FY26, leading to significant consumption.

    03

    High-Bandwidth Flash (HBF) Technology Development

    Sandisk unveiled its High-Bandwidth Flash (HBF) technology, receiving a "Best of Show" award. The company is establishing a technical advisory board and formed an ecosystem partnership with SK Hynix to standardize HBF specifications. HBF technology is expected to be available by H2 CY26, with product samples (including controller) in H1 CY27, targeting AI inference applications from edge to cloud, and is viewed as a new paradigm for inference.

    04

    Market Dynamics and Pricing Actions

    Management estimates overall demand exceeded supply in Q4 FY25 and anticipates this undersupply to continue through CY26, with mid-single-digit undersupply expected for FY26. The company began implementing price increases in Q4 FY25 and expects further increases, with bits growth in FY26 consistent with broader market demand growth (low double digits in CY25, mid-to-high double digits in CY26). Some products are currently on allocation due to strong demand.

    05

    Inventory and Debt Management

    Sandisk successfully reduced inventory days from 150 to 135 in Q4 FY25, aligning supply with demand and indicating a tighter market. The company also reduced net debt to $368 million, making significant prepayments on its Term Loan B ($95 million in Q4 and an additional $100 million post-quarter), and remains on track to become net cash positive, reflecting confidence in future cash flow generation.

    06

    Client and Consumer Market Performance

    In the client market, growth was driven by rising average capacity across mobile and PC markets, with BiCS 8 SSDs now qualified across all major PC OEMs. In consumer, the Sandisk brand is strengthening through differentiated product innovation, including a new USB4 portable SSD and co-branded products for Nintendo Switch 2 and Xbox, indicating positive customer response across high-value use cases.
