According to South Korean media reports, LG Display (LGD) is grappling with an uncomfortably high level of revenue concentration on a single major customer, even as the company has successfully restructured its business toward higher-margin OLED panels.
In its 2015 full-year business report, LG Display posted sales of 25.81 trillion Korean won (approximately $23.5 billion at the time), representing a 3% year-on-year decline. However, the company achieved a notable turnaround, recording an operating profit of 5.17 trillion Korean won after previous losses. The shift in business structure to focus on profitable OLED technology was credited as a key driver behind the improved performance.
Despite the positive earnings momentum, concerns remain over LG Display's heavy reliance on one client. According to the report, the company's largest customer accounted for 14.8359 trillion Korean won in sales last year - equivalent to roughly 57.5% of its total annual revenue. Industry observers widely believe this dominant client is Apple, which procures OLED panels primarily for its iPhone lineup.
Revenue concentration of this magnitude is often viewed as a double-edged sword. On one hand, it provides LG Display with a reliable "cash cow" that delivers stable and substantial income. On the other, it leaves the company's overall performance highly vulnerable to the purchasing decisions and strategic shifts of that single buyer.
Recent market sentiment in the smartphone sector has turned cautious. Rising memory chip prices have increased cost pressures across the supply chain, while global smartphone shipments are forecast to decline. Market research firm Counterpoint Research predicts that worldwide smartphone shipments will drop by 12.4% year-over-year in 2026, falling slightly below 1.1 billion units - marking the lowest annual total since 2013.
A display industry source noted: "iPhone shipments are expected to remain relatively resilient compared to lower-priced smartphone brands. However, if Apple responds to cost pressures by negotiating lower panel prices, LG Display's profitability could face significant downward pressure."
Another point of concern is LG Display's absence from the foldable OLED panel supply chain. Since the company does not currently supply foldable OLED panels, analysts believe it will miss out on potential revenue opportunities from Apple's anticipated foldable iPhone models expected to launch and ramp up shipments this year.
As the display industry continues to evolve rapidly with new form factors and intensifying competition, LG Display's heavy dependence on its largest client highlights both the rewards and risks of its current business model. The coming months may test how well the company can diversify its customer base while maintaining its OLED leadership.
