Summary
S&P Global Ratings raised Sandisk Corp.'s corporate rating to BB+ from BB yesterday, citing the company's elimination of all debt and its transition to a net cash position when measured using S&P's adjusted credit metrics. The ratings firm also upgraded Sandisk's revolving credit facility to BBB- with a recovery rating of 1 and withdrew issue-level ratings tied to the company's term loan.
Financial position and policy
S&P highlighted Sandisk's $3.7 billion cash balance and its net cash standing after the adjustments the ratings firm applies, which incorporate guarantees on equipment leases tied to manufacturing joint ventures. The positive outlook attached to the rating signals the potential for additional upward movement should Sandisk maintain its net cash position and carry out share repurchases.
Sandisk has authorized a $6 billion share repurchase program. S&P stated that the company should be able to execute that program while preserving a net cash position, given the ratings firm's expectations for robust cash flow generation.
Market dynamics and operational performance
The upgrade reflects favorable market dynamics in NAND memory, where supply constraints have supported price appreciation. Sandisk reported a 191% year-over-year increase in data center revenue. In the April quarter, S&P said that all of Sandisk's segments recorded more than 100% year-over-year increases in average selling price per gigabyte.
S&P does not anticipate a near-term industry downturn, noting that competitors are focusing on HBM products rather than rapidly expanding NAND capacity, which supports the current supply-demand balance. The ratings firm also observed that strong demand from data center customers has prompted some of them to enter long-term agreements that include volume commitments and mixed pricing structures.
Forward financial expectations
S&P projects Sandisk's revenue to reach $19 billion in 2026 and to exceed $30 billion in fiscal 2027. The firm forecasts EBITDA margins of 62% in 2026 and above 70% in 2027, outcomes S&P attributes to continued price gains and cost improvements tied to BiCS8 technology. Capital expenditures are expected to be in the $600 million to $650 million range, directed toward back-end facilities and Flash Ventures equipment.
Based on those assumptions, S&P estimates free cash flow of about $6 billion for the fiscal year ending June 2026 and in excess of $15 billion in 2027.
Competitive landscape and customer concentration
S&P noted that Sandisk operates in a competitive environment that includes Samsung Electronics, SK Hynix, and Micron Technology. The ratings firm pointed out that Sandisk's top 10 customers accounted for 40% of fiscal 2025 revenue.
Outlook and potential downside triggers
The ratings agency said it could revise the outlook to stable if industry conditions weaken or if Sandisk no longer maintains its adjusted net cash position. That caveat frames the primary downside risks S&P is monitoring despite the current upgrade.
