MagnaChip Semiconductor (symbol: MX) sells primarily to other companies (B2B).
According to its latest Annual Report (10-K filing for the fiscal year ended December 31, 2023), MagnaChip Semiconductor has a highly concentrated customer base. Sales to its top three customers accounted for 43% of total net sales in 2023, and sales to its top ten customers accounted for 79% of total net sales. However, MagnaChip's public filings do not explicitly name any specific major customers. This indicates that no single customer individually accounted for 10% or more of its net sales during the reporting period, which would require mandatory disclosure by the U.S. Securities and Exchange Commission.
MagnaChip generally serves the following categories of customers:
- System manufacturers
- Independent distributors
- Contract manufacturers

The increasing vertical integration and captive supply chain strategies within the display panel industry pose a clear emerging threat. Major display panel manufacturers and large mobile device OEMs are increasingly developing their own Display Driver ICs (DDICs) internally or forging exclusive, deeply integrated partnerships with specific DDIC suppliers. This trend limits the addressable market for independent DDIC providers like MagnaChip, reduces design-in opportunities, and intensifies competitive pressure as key customers transition away from a broad supplier base towards internalized or tightly coupled solutions.

MagnaChip Semiconductor (MX) is strategically repositioning itself to drive future revenue growth over the next two to three years, primarily by focusing on its Power business and expanding into high-growth markets. Key anticipated drivers include:
-
Transition to a Pure-Play Power Business: MagnaChip's decision to become a pure-play Power company, with plans to exit its Display business by the end of the second quarter of 2025, is a fundamental shift aimed at enhancing revenue growth and profitability. This focus allows the company to concentrate resources on higher-potential areas.
-
Launch of New-Generation Power Products: The company is aggressively introducing a pipeline of advanced power products, including Gen 5 and Gen 6 IGBTs, Gen 6 SuperJunction MOSFETs, and Gen 8 medium- and low-voltage MOSFETs. MagnaChip plans to launch over 50 new-generation power products in 2025, with these products expected to drive higher revenue per wafer and improve gross margins as they gain traction in the market.
-
Expansion into High-Value Markets (Automotive, Industrial, AI, Renewable Energy): The new power products are designed to unlock significant opportunities in high-growth markets such as automotive, industrial, artificial intelligence (AI), and high-current applications. MagnaChip targets these segments to comprise over 60% of its future product mix by 2028, a substantial increase from 37% in 2024. The automotive market alone is projected to contribute over 10% of revenue by 2027.
-
Strategic Licensing Agreement with Hyundai Mobis: A strategic licensing agreement with Hyundai Mobis for Insulated Gate Bipolar Transistor (IGBT) technology is expected to expand MagnaChip's presence beyond automotive into the industrial, AI, and renewable energy sectors. This partnership is poised to open new revenue streams, with Hyundai Mobis planning mass production of inverters incorporating these IGBTs in 2026.
-
Growth in the Communications Segment: The Communications segment has demonstrated strong performance, with revenue increasing by 34% sequentially and 95% year-over-year in the third quarter of 2025, indicating its potential as a significant contributor to future revenue.
