CluenexSanDisk SNDK
SanDisk scores excellent on business quality (9.2 of 10). Here is why, in plain words, and what our sealed record shows.
Why it matters
- What SanDisk does
Sandisk designs and sells flash memory storage solutions, supplying components that power consumer and enterprise data storage. Enterprises and device manufacturers pay for high-capacity memory to support massive data workloads.
- What it does best
Sandisk converts revenue into free cash flow at an exceptional rate, posting a 56.5% net margin that outpaces peers like Apple's 29.3%. This cash conversion power stems from elite manufacturing efficiency and high-demand specialized memory lines.
- The main risk
The primary threat is whether the AI storage boom can sustain current profit surges. If enterprise demand for high-capacity memory moderates, the sharp revenue leap to $20.2B faces severe cyclical compression.
Quality, check by check
Scored against its own industry, from company filings.
Gross margin sits at 71.5% with operating margin at 61.2%, both expanding rapidly on surging AI storage demand. The business demonstrates extreme operational leverage as revenue scales.
The moat relies on proprietary flash memory technology that locks in major enterprise tech buyers. Operating in the top decile for operating margin at 97th percentile, rivals face steep technological barriers.
Revenue growth surged 175% to $20.2B, vastly accelerating compared to historical flat periods. The AI storage boom serves as the main engine driving this massive top-line expansion.
Interest coverage hits 169x, making debt servicing a non-factor alongside $4.8B in cash. Free cash flow reached $11.5B, showing an exceptionally strong balance sheet and cash generation profile getting stronger.
