MRAM - Everspin Technologies, Inc.

Everspin Technologies manufactures Magnetoresistive RAM (MRAM) and Spin-transfer Torque MRAM (STT-MRAM) chips, which are non-volatile memory semiconductors that combine the speed of SRAM with the persistence of flash memory. The company sells primarily to enterprise and industrial OEMs — including storage controller makers, industrial automation vendors, and aerospace/defense integrators — under a direct and distributor B2B model. Everspin generates approximately $50-60M in annual revenue, with the majority of sales concentrated in North America and Asia-Pacific, particularly in data center storage and industrial end markets.

Past Year Trends

• Everspin reported FY2024 revenue of approximately $49M, down roughly 13% from $56.6M in FY2023, as HDD write-cache demand from its two largest customers Western Digital and Seagate contracted sharply amid the ongoing enterprise hard-drive inventory correction. (Bearish)
• Everspin launched its 1Gb xSPI-interface STT-MRAM product in 2024, targeting industrial, automotive, and IoT end-markets to reduce reliance on the HDD segment, which represented the first meaningful product-line expansion beyond the legacy Toggle MRAM and SPI MRAM SKUs. (Bullish)
• Gross margin compressed to the low-to-mid 50% range in 2024 (vs. approximately 57% in 2023) as lower factory utilization at Everspin's Chandler, AZ fab drove up per-unit fixed-cost absorption on reduced HDD-related production volumes. (Bearish)

Next Year Trends

• A recovery in enterprise HDD build rates at Western Digital and Seagate—Everspin's top two customers representing over 50% of product revenue—is the single largest revenue lever; any delay in the HDD upcycle directly limits MRAM unit shipment growth in 2025-2026. (Neutral)
• Commercial ramp of the 1Gb xSPI STT-MRAM into automotive-grade and industrial customers is expected to begin contributing meaningful design-win revenue in late 2025 and 2026, though qualification cycles at Tier-1 automotive suppliers typically run 18–24 months and could push revenue recognition into 2027. (Bullish)
• Everspin's fab capacity and capital structure constrain its ability to scale rapidly if demand recovers simultaneously across HDD and industrial segments, and the company has historically operated near breakeven on an operating-income basis, making it vulnerable to any renewed top-line shortfall without a clear path to a second manufacturing source or foundry partnership.
