LG Display Reports First Quarter 2026 Results

SEOUL, Korea (Apr. 23, 2026) – LG Display today reported unaudited earnings results based on consolidated K-IFRS (International Financial Reporting Standards) for the three-month period ending March 31, 2026.

Revenues in the first quarter of 2026 decreased by 23% to KRW 5,534 billion from KRW 7,201 billion in the fourth quarter of 2025 and decreased by 9% from KRW 6,065 billion in the first quarter of 2025.

Operating profit in the first quarter of 2026 decreased by 13% to KRW 146.7 billion from KRW 168.5 billion in the fourth quarter of 2025 and increased by 338% from KRW 33.5 billion in the first quarter of 2025.

EBITDA in the first quarter of 2026 was KRW 1,141 billion, compared with EBITDA of KRW 1,162 billion in the fourth quarter of 2025 and KRW 1,231 billion in the first quarter of 2025.

Net loss in the first quarter of 2026 was KRW 576 billion, compared with the net loss of KRW 351 billion in the fourth quarter of 2025 and with the net loss of KRW 237 billion in the first quarter of 2025.

LG Display recorded KRW 5.53 trillion in revenues and KRW 146.7 billion in operating profit in the first quarter of 2026.

The company’s operating profit increased by 338% year-on-year, marking its third consecutive quarter of profitability. This performance was driven by its business portfolio centered on OLED and high-end strategic customers, along with cost reduction technologies and enhanced operational efficiency.

Despite the seasonal slowdown, the proportion of OLED products contributing to total revenues rose by 5 percentage points year-on-year to 60%. As a result, average selling price per area increased by 55% compared to the same period last year.

TV panels accounted for 16% of revenues in the first quarter, while IT panels - including monitors, laptops, and tablet PCs - accounted for 37%. Panels for mobile and other devices accounted for 37%, and automotive panels accounted for 10% of revenues.

LG Display is reinforcing its business competitiveness with a focus on OLED, while continuing to drive cost innovation and operational efficiency to establish a sustainable profit structure.

In its small-sized business, the company will respond flexibly to diverse customer technology needs based on its technological leadership and stable supply capabilities. At the same time, it plans to efficiently utilize its existing production infrastructure to prepare for future growth.

In its mid-sized business, LG Display aims to continue improving profitability by focusing on high value-added products, leveraging its differentiated Tandem OLED and high-end LCD technologies to actively respond to customer demand.

In its large-sized business, the company plans to strengthen its premium product lineup based on its world-leading technologies, while also expanding more price-competitive offerings. In particular, as the monitor market is rapidly transitioning to OLED, LG Display will broaden its gaming product lineup featuring proprietary technologies to maximize business opportunities and expand its customer base.

“Amid ongoing external uncertainties, our competitiveness in high-spec products - where we have strong advantages - is strengthening, along with higher technological barriers,” said Sung-hyun Kim, CFO at LG Display. He added, “We will secure financial stability by continuing to enhance technological differentiation through company-wide efforts, and deliver sustainable performance that meets the expectations of the market and our customers.”
