The company's focus on being the leading merchant supplier (selling to all major NAND flash makers) instead of a captive supplier is a key differentiator, supporting more NAND flash components from companies like Kioxia, Micron, and Samsung than any other controller company. They operate as a fabless semiconductor company, focusing on design and intellectual property and outsourcing manufacturing, which allows for high gross margins.
Cyborg Score Rationale
The company maintains strong non-GAAP gross margins of 48.7% in Q3 2025 with Q4 2025 guidance projecting 48.5% to 49.5%. Q3 2025 net sales of $242.0 million represented a 14% year-over-year increase, with the company on track to exceed an annual revenue run rate of $1 billion exiting Q4 2025. Market leadership in a critical infrastructure segment supports strong positioning.
