Our total equity amounted to W7,839 billion as of December 31, 2025, representing a decrease of W237 billion from the end of the previous year. The decrease in total equity was primarily attributable to a decrease in non-controlling interests following the sale of our large-sized LCD panel manufacturing subsidiaries.
In light of the increasing uncertainties in the external business environment and intensifying competition among display panel manufacturers, we have continued to enhance our business structure to strengthen profitability and have continually engaged in activities to restore our financial soundness. We are dedicated to improving our key financial indicators such as our liabilities-to-equity ratio by stabilizing our financial structure.
(4)Dependence on Key Customers
We sell our products to a select group of key customers, including our largest shareholder, and any significant decrease in their order levels will negatively affect our financial condition and results of operations.
A substantial portion of our sales is attributable to a limited group of end-brand customers and their designated system integrators. Sales attributed to our end-brand customers are for their end-brand products and do not include sales to these customers for their system integration activities for other end-brand products, if any. Our top ten end-brand customers, including LG Electronics Inc., our largest shareholder, together accounted for approximately 87% of our sales in 2023, 89% in 2024 and 92% in 2025.
We benefit from the strong collaborative relationships we maintain with our end-brand customers by participating in the development of their products and gaining insights about levels of future demand for our products and other industry trends. Customers trust our ability to supply differentiated and quality products even during downturns in the industry, and we benefit from the brand recognition of our customers’ end products. The weakening of our ties with these end-brand customers, as a result of their entering into strategic supplier arrangements with our competitors or otherwise, would thus result in reduced sales and the loss of the aforementioned benefits. We cannot provide assurance that a select group of key end-brand customers, including our largest shareholder, will continue to place orders with us in the future at the same levels as in prior periods, or at all.
We expect that we will continue to be dependent upon LG Electronics and its affiliates for a significant portion of our revenue for the foreseeable future. Our results of operations and financial condition could therefore be affected by the overall performance of LG Electronics and its affiliates. Further details of our transactions with LG Electronics and its affiliates are described in Note 29 of the notes to our consolidated annual financial statements of the notes to our consolidated financial statements included elsewhere in this report.
Our revenue depends on continuing demand for IT products (comprising notebook computers, desktop monitors and tablet computers), televisions, mobile products, automobiles and other devices with panels of the type we produce. Our sales may not grow at the rate we expect if consumers do not purchase these products.
Currently, our total sales are derived principally from customers who use our products in IT products (comprising notebook computers, desktop monitors and tablet computers), televisions, automobiles, mobile devices and other products with display devices. In particular, a substantial percentage of our sales is derived from end-brand customers, or their designated system integrators, who use our panels in their IT products, which accounted for 36.8%, 35.4% and 36.8% of our total revenue in 2023, 2024 and 2025, respectively. A substantial portion of our sales is also derived from end-brand customers, or their designated system integrators, who use our panels in their mobile and other products, which accounted for 33.5%, 33.6% and 36.3% of our total revenue in 2023, 2024 and 2025, respectively, those who use our panels in their televisions, which accounted for 20.3%, 22.4% and 18.6% of our total revenue in 2023, 2024 and 2025, respectively, and those who use our panels in their auto products, which accounted for 9.4%, 8.6% and 8.3% of our total revenue in 2023, 2024 and 2025, respectively. Due to the structure of our sales, we will continue to be affected by demand from the IT products industry (comprising the personal computer and tablet computer industries), mobile device industry, television industry and automobile industry. Any downturn in any of such industries in which our customers operate may result in reduced demand for our products, which may in turn result in reduced revenue, lower average selling prices and/or reduced margins.
(5)Changes in Manufacturing Costs and Difficulties in Securing Supply of Raw Material
If we cannot maintain high capacity utilization rates, our profitability will be adversely affected.
The production of display panels entails high fixed costs resulting from considerable expenditures for the construction of complex fabrication and assembly facilities and the purchase of costly equipment. We aim to realize a higher gross margin and strive to maintain high capacity utilization rates so that we can allocate fixed costs over a greater number of panels produced. However, due to fluctuating demand for our products or overcapacity in the display industry, we may need to adjust utilization rates to a level that is lower than optimal and reduce production. As such, we cannot provide assurance that we will be able to maintain high capacity utilization rates in the future due to possibilities of fluctuation in market and industry conditions.
