(Unit: Won, Shares)

We have no outstanding convertible bonds as of March 31, 2026.

Dividends for the three most recent fiscal years

Historical dividend information(1)

This information is omitted in quarterly reports in accordance with Korean disclosure rules, and we plan to include such information in our semi-annual and annual reports.

We were incorporated in February 1985 under the laws of the Republic of Korea. LG Electronics and LG Semicon transferred their respective LCD business to us in 1998, and since then, our business has been focused on the research, development, manufacture and sale of products that apply display technologies such as OLED and TFT‑LCD. Sorting by major sales product category, television, IT products, mobile and other products, and “auto” products (comprising automotive display products) accounted for 16%, 36%, 38% and 10% of our total sales, respectively, in the first quarter of 2026. Our customers primarily consist of global set makers, and our top ten customers comprised 93% of our total sales revenue in the first quarter of 2026. As a company focused on exports, our overseas sales accounted for approximately 95% of our total sales in the first quarter of 2026. We have overseas sales subsidiaries located in the United States, Germany, Japan, Taiwan, China and Singapore.

We operate key production facilities in Korea, China and Vietnam, and our cumulative annual production capacity for the first quarter of 2026 was approximately 0.9 million glass sheets, as converted into eighth-generation sheets (2200x2500mm). In order to expand our production capacity of differentiated and competitive products such as OLED panels, our total capital expenditures on a cash out basis was around W1.4 trillion in 2025. In 2026, we plan to increase our capital expenditures to the mid-to-upper W2 trillion range, representing an increase from the previous year.

The major raw materials for display panel production include glass, semiconductors, polarizers, organic matter, backlight units (“BLU”) and printed circuit boards (“PCB”), and the prices of our raw materials may fluctuate as a result of supply and demand in the market as well as changes in our purchase quantity.

The display industry to which we belong is highly affected by the global economic conditions. Given the characteristics of the display business, which requires large-scale investments, display panel prices may fluctuate due to an imbalance between supply and demand, which may affect our profitability. The sales performance of industry players is differentiated by not only the production capacity of each company but also other competitive differences arising from factors including technology, cost structure, product development capability, manufacturing efficiency, quality control and customer relationships, as well as by differentiation in sales volume and pricing utilizing such factors. In addition, given the high proportion of our sales overseas, our sales of display panels are denominated mainly in U.S. dollars whereas our purchases of raw materials are denominated mainly in U.S. dollars, Japanese Yen and Chinese Yuan. Accordingly, our profit margins may be affected by changes in the exchange rates between the currencies. We strive to minimize the risk relating to foreign currency denominated assets, liabilities and operating cash flow due to exchange rate fluctuations.

Our research and development expenses represent approximately 10% of our sales, and we are continually creating customer value through systematic R&D activities for new products and technologies. Leveraging our competitive R&D activities, we are leading the display market by providing differentiated values in display panel products utilizing our OLED and TFT-LCD technologies for various uses including television, IT, mobile products and automobiles.

Consolidated operating results highlights

(Unit: In billions of Won)

The display panel industry is expected to continue to grow, as the essential role of display products as a key device for information and communication in daily lives of individuals as well as for industrial purposes becomes more pronounced. We are strengthening our business competitiveness based on customer value and developing new markets under our strategic plan to transition our business to center around OLED, which has a strong growth potential within the display panel industry. With respect to large-sized display panels, we are focusing on expanding the OLED market through differentiated products and technology, such as META technology, which offers high-resolution and high-luminance, and Tandem WOLED technology, as well as strengthening business with new customers. We are also leading the expansion into new product areas, such as gaming display panels. In the medium-sized display panel business, we are increasing the proportion of premium products such as high resolution and wide screen products based on IPS and oxide technologies, and we are also increasing the use of OLED panels in IT products to improve power consumption and provide differentiated form factors. In the small-sized display panel business, we have secured high value-added and differentiated technology and stable operating capabilities for 6th generation plastic OLED smartphone displays, while also expanding our customer base in the automotive display panels business by providing optimized display solutions featuring high resolution, high refresh rates and high luminance, based on a diverse portfolio of premium products including plastic OLED, advanced thin OLED and LTPS LCD panels. We are also in the process of proactively preparing the technology to respond to new market opportunities for ultra-small-sized displays, including those in relation to augmented reality and virtual reality uses.

For our continued growth, we are actively exploring and preparing for new business opportunities in response to the changing market environment. As such, we are continually reviewing and looking at opportunities in the display and promising new industries.

Through engaging in detailed analysis and acquiring insight on the market and industry conditions, technology, products and end-user consumers, we seek to provide differentiated values that are customer- and consumer-friendly. In addition, we engage in activities that are geared to proactively identify and offer meaningful benefits to customers and consumers. As a result, we are continually developing products that provide differentiated values using our technologies. At the same time, we strive to create new markets and mutually benefit our business and our customers by obtaining customer trust and satisfaction through our customer- and consumer-oriented marketing activities.

We manufacture OLED and TFT‑LCD panels, of which a significant majority is sold overseas.

(Unit: In billions of Won, except percentages)

The average selling prices of display panels are subject to change based on market conditions and demand by product category. The average selling price of display panels per square meter of net display area shipped in the first quarter of 2026 was USD 1,244, representing a decrease from the previous quarter primarily due to a decline in shipments of small- and medium-sized OLED panels, which carry relatively higher average selling prices per square meter, as a result of seasonal factors. The average selling prices of display panels per square meter of net display area may continually fluctuate in the future due to changes in market conditions, demand trends and our product mix.

(Unit: US$ / m2)

Prices of major raw materials depend on fluctuations in supply and demand in the market as well as on changes in size and quantity of raw materials due to the increased production of large‑sized panels.

Our business is exposed to credit risk, liquidity risk and market risk. Accordingly, we operate a risk management system that identifies and analyzes these risks while monitoring and managing risk level by establishing appropriate risk controls in order to ensure that such risks do not exceed certain threshold levels.

See Note 24 to our consolidated financial statements attached hereto for more information regarding our exposure to each of the risks listed above.

In order to manage our risk against foreign currency fluctuations, we eliminate such risk by adopting a policy of maintaining our net exposure risk within an acceptable level by buying or selling foreign currencies at spot rates, when necessary, to address short-term imbalances in the inflow and outflow of foreign currency funds. We also continually monitor our currency position and risk for other monetary assets and liabilities denominated in foreign currencies, and when needed, we may from time to time enter into cross‑currency interest rate swap contracts and foreign currency forward contracts. Furthermore, we have adopted a policy aimed at minimizing uncertainty and financial costs arising from interest rate fluctuations and manage our interest rate risk through periodic monitoring of interest rate trends and adoption of appropriate countermeasures.

Our material contracts, other than contracts entered into in the ordinary course of business, are set forth below:

(Unit: In millions of Won, except percentages)

* Dual Resolution : UHD 165Hz ↔ FHD 330Hz

1) 22.3” Module for 136” 4K business-to-consumer products

As of March 31, 2026, our cumulative patent portfolio (including patents that have already expired) included 32,014 patents in Korea and 39,318 patents in other countries. In 2026, we registered 369 patents in Korea and 630 patents in other countries.

In order to minimize the environmental impact of our business activities, we are actively responding to environmental regulations applicable to our products and business sites.

We have installed and operate various types of prevention facilities to minimize the emission of environmental pollutants generated in our production process. With respect to air and water pollutants, we set and manage our internal standard at 70% of the permitted levels under the regulatory emission standards. In addition, in order to establish a resource circulation system, we operate a proprietary system to monitor waste from its generation to treatment, have developed waste treatment technology and identified suitable recycling companies to reduce the amount of waste we generate and maximize recycling.

In addition, as we were designated a target company for the greenhouse gas emission trading system in 2015, we allocate and monitor our greenhouse gas emissions every year. In order to continually promote the reduction of greenhouse gas emissions, we have set a medium- to long-term goal to reduce the emission level by continually investing in facility improvements and monitoring our emission levels.

We are subject to a variety of environmental laws and regulations, and operations at our manufacturing plants are subject to regulation and periodic scheduled and unscheduled on‑site inspections by the Ministry of Environment and local environmental protection authorities. The primary types of environmental laws applicable to us include the following:

Through the implementation of an environmental and energy management system, we are continuously making efforts to minimize environmental impact and reduce energy usage in all aspects of our business process. Accordingly, we have acquired and currently operate the environmental management system ISO14001 and energy management system ISO 50001 certifications for all of our domestic and overseas production sites. In addition, we have established company-wide safety, healthy, energy and environment management policies and manuals, which are regularly updated based on international standards. We also conduct systematic management of our business process in accordance with international standards through annual follow-up and renewal audits.

We have been participating in the Carbon Disclosure Project (“CDP”), a globally recognized authority on environmental disclosure, and named to the Honors Club in the IT category of the Climate Change Korea Awards for ten consecutive years from 2016 to 2025. The ‘Carbon Management Sector Honors’ is awarded to top-performing companies by industry sector based on the results of the CDP Climate Change assessment. We received a Leadership A- rating, which is one of the higher rating categories in the assessment, in key areas including greenhouse gas reduction and management efforts, advancement of climate change response scenarios and expansion of renewable energy utilization. In addition, we achieved a Leadership A rating, which is among the highest rating categories, in the CDP Water Security assessment, in recognition of our systematic management efforts, including the expansion of actual water reuse and the transparent public disclosure of our water resource data management performance.

In addition, in recognition of our efforts to improve recycling rates and reduce waste, we were nominated as a leading company with an excellent performance in resource circulation and received a commendation from the Minister of Environment in 2020. In 2022, we achieved the Gold rating for Zero Waste to Landfill (“ZWTL”) for our Paju and Gumi facilities and the Platinum rating for our Nanjing facility. Through ongoing efforts to improve our recycling rate, our Paju facility achieved a Platinum rating for the first time in June 2024 and our Guangzhou facility achieved a Platinum rating for the first time in December 2024. Subsequently, our Gumi facility achieved a Platinum rating for the first time in July 2025, while our Paju facility maintained its Platinum rating following the reassessment in July 2025. In November 2025, we achieved the Gold rating for our Vietnam facility, completing ZWTL certification for all of our production sites. In 2022, we introduced a resource recirculation recognition program in accordance with the Korean government’s waste management policy and received circular resource certification on eight types of our discarded trays and vinyl. In 2023, we have obtained quality certification for certain of our recycled items recognized as circular resources, and we plan to continue to promote the resource circulation of our products. We will continue our efforts to reinforce our resource circulation program by minimizing waste and maximizing recycling rate.

We have continued to pursue ESG management activities based on the spirit of “value creation for consumers” and “human-first management,” and we plan to obtain further recognition for our eco-friendly management and share relevant information with the stakeholders.

In order to respond to applicable domestic and overseas environmental regulations, such as the European Union’s Restriction of Hazardous Substances (RoHS) and Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) that restrict the use of certain hazardous substances, we operate a hazardous substance management program that implements a four-step procedure (each such step, a “Gate”) that manages various stages of our production cycle, beginning with the registration process of our business partners up to the mass production stage. In addition, in order to preemptively address four types of phthalate substances that became additionally regulated pursuant to the RoHS in 2016 and officially went into effect on July 22, 2019, we replaced the latent risk elements in advance as well as implemented a more stable management process with respect to such substances. In implementing this process, we collaborated with external agencies to ascertain regulatory trends and establish our response strategy, and we formulated and applied effective management measures through the collaborative efforts of our development, procurement, quality assurance and analysis teams.

- Gate 01 (Business Partner Stage): An audit is conducted prior to the registration of a new business partner (including the inspection of the business partner’s hazardous substance response process)

- Gate 02 (Parts Development Stage): An environmental evaluation of each part under development is conducted (consisting of three stages: (1) document review; (2) XRF test and (3) precision analysis)

- Gate 03 (Product Development Stage): An environmental evaluation of the product model and product labeling are conducted (including RoHS verification)

- Gate 04 (Mass Production Stage): Process management through the periodic testing of mass-produced parts for any hazardous substances (including rate-based tests based on risk assessment)

We operate a “Hazardous Substance Management System for Products” that effectively manages hazardous substances by classifying them into four levels: A-I, A-II, B-I, and B-II. In particular, in addition to substances prohibited by global hazardous substance regulations on products, we have designated substances causing harm to the human body and the environment as Level B substances. By developing alternative technologies and parts and applying them to our products, we continually strive to achieve a gradual reduction and elimination of non-prohibited hazardous substances.

- Level A-I (Prohibited Substances): Prohibited substances designated under the RoHS regulations (i.e., 10 regulated substances) and those designated by specific customers

- Level A-II (Prohibited Substances): Substances prohibited by regulations and conventions other than those covered under Level A-1 and those designated as such by customers

- Level B-I (Substances Subject to Voluntary Reduction): Substances that are being voluntarily replaced over a certain period of time

- Level B-II (Substances Under Observation): Substances that are not currently banned, but are expected to become prohibited in the future

Moreover, we participated in reforming IEC 62321, an international testing standard published by the International Electrotechnical Commission and used by RoHS, and the commission adopted our halogen‑free combustion ion chromatography method as IEC 62321‑3‑2, which was published in June 2013.

In 2017, we became the first display panel company to receive the SGS Eco Label accreditation for OLED television display modules from SGS, a global product testing/accreditation agency, and have since continually received such accreditation. In 2024, such accreditation has been updated to “SGS EEPS accreditation.” In 2022, we expanded our accreditation program to cover display modules for monitors, notebook computers, tablets and automobiles, as a result of which our display modules for monitors and notebook computers received SGS Eco Label accreditation for the first time and our automotive display module became the first in the industry to receive the same accreditation for its excellence in energy efficiency, and we have since maintained the SGS Eco Label for such products. In 2023, our high-end LCD panels for 16-inch notebooks and 27-inch monitors, in which we incorporated recycled materials for the first time, received the SGS Eco Label accreditation. In addition, our 30-inch and 55-inch transparent display products, for which we applied hazardous substance reduction technology, became the first in the industry to receive the SGS Eco Label accreditation.

Moreover, in 2022, our 27-inch monitor display product that applied anti-bacterial films received the SGS Performance Mark accreditation for its anti-bacterial performance, and in 2023, our commercial display module that applied Plus-Bright energy

consumption reduction technology obtained the SGS Performance Mark accreditation for its energy efficiency performance. Our high-end LCD panels for 16-inch notebooks and 27-inch monitors also received the same accreditation for reducing energy consumption through the implementation of proprietary algorithms and improving panel transmittance. In 2025, we enhanced and replaced PFAS-containing components in our 14-inch LCD panels for notebook computers, and as a result, obtained the SGS ECCS Mark – PFAS Screened accreditation.

Also in 2022, upon assessment and verification of GHG emissions throughout its entire product life cycle, our OLED television panel received the industry’s first Carbon Footprint Certification from The Carbon Trust, a not-for-profit company founded by the United Kingdom government that provides voluntary carbon certification services and carbon labeling schemes. In 2023, our high-end IT LCD panels (27-inch and smaller) received the Product Carbon Footprint (PCF) certification from TÜV Rheinland, a global independent testing, inspection and certification agency, by achieving carbon emission reduction through the application of recycled materials and low energy consumption technologies. Our OLED panels for automotive products also received the same certification for achieving carbon emission reduction through the application of light-control film integration technology. In 2024, our 14-inch high-end LCD panel product for notebook computers received the Product Carbon Footprint Reduction (PCR) certification from TÜV Rheinland through the application of bio-plastic, recycled materials and ultra-precision micro-processing technology. Additionally, upon verification by Underwriters Laboratories (UL), a global inspection and certification agency, such display panel also received the Environmental Claim Validation (ECV) certification. In 2025, we obtained the “Product Carbon Footprint Methodology” certification from TÜV Rheinland reflecting our establishment of a system to calculate carbon emissions generated throughout the entire product life cycle based on international standards and our proprietary evaluation methodology optimized for display panels, as well as an IT system for evaluating product carbon footprints.

In 2021, we received the “Green Technology Certification” for our advanced incell touch display technology, an eco-friendly technology with touch-sensing electrodes and transmission lines that reduce carbon emissions and the use of rare metals. Also, since 2021, we have continued to obtain an eco-friendly certification from TUV SUD, a globally recognized accreditation agency based in Germany, for excellence in resource circulation and compliance with Waste Electrical and Electronic Equipment (WEEE) regulations and the non-use of specific hazardous substances in our OLED television display panels, plastic OLED mobile and smartwatch display products, OLED tablet display panels and TFT-LCD panels for IT products.

In 2018, we became the first display panel company to receive the “Green Technology Certification” from the Korean Ministry of Science and ICT for improving the light efficiency technology of OLED to promote energy use reduction. In 2017, for the IPS Nano Color for LCD, we received the Quality & Performance Mark from Intertek, a global product testing/accreditation agency, by applying a technology to eliminate cadmium (Cd) and indium phosphide (InP).

Our products comply with the IEC 62638-1 global product safety standards, and we obtain CB and UL certifications on applicable products.

In order to promote the enhancement of safety for automobile manufacturers and consumers, we became the first display panel company in June 2016 to introduce a flame-resistant certification program for our display panels, which program includes flame resistance standards for automotive materials (including ISO 3795, DIN 75200 and FMVSS 302 standards) as well as for safety standards for information technology devices, which has been certified by TUV SUD. In 2025, we expanded the number of applicable flame resistance standards for such program from 9 to 14.

Furthermore, in 2021, we established infrastructure for flammability tests required under the United States Federal Aviation Administration’s FAR 25.853 standards and impact tests under RTCA DO-313 standards, and the reliability of these test results have been certified by TUV SUD.

Report on Review of Condensed Consolidated Interim Financial Statements

(English Translation of a Report Originally Issued in Korean)

To the Shareholders and Board of Directors of

LG Display Co., Ltd.

Reviewed Financial Statements

We have reviewed the accompanying condensed consolidated interim financial statements of LG Display Co., Ltd. and its subsidiaries (collectively referred to as the “Group”). These condensed consolidated interim financial statements consist of the consolidated interim statement of financial position of the Group as at March 31, 2026, and the related consolidated interim statements of comprehensive income, changes in equity and cash flows for the three-month periods ended March 31, 2026 and 2025, and material accounting policy information and other selected explanatory notes, expressed in Korean won.

Management's Responsibility for the Financial Statements

Management is responsible for the preparation and presentation of these condensed consolidated interim financial statements in accordance with International Financial Reporting Standards as adopted by the Republic of Korea (Korean IFRS) 1034 Interim Financial Reporting, and for such internal control as management determines is necessary to enable the preparation of condensed consolidated interim financial statements that are free from material misstatement, whether due to fraud or error.

Auditor's Responsibility

Our responsibility is to express a conclusion on these condensed consolidated interim financial statements based on our review.

We conducted our review in accordance with quarterly or semi-annual review standards established by the Securities and Futures Commission of the Republic of Korea. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Korean Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe the accompanying condensed consolidated interim financial statements are not prepared, in all material respects, in accordance with Korean IFRS 1034 Interim Financial Reporting.

Other Matters

We have audited the consolidated statement of financial position of the Group as at December 31, 2025, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the year then ended, not presented herein, in accordance with Korean Standards on Auditing. We expressed an unqualified opinion on those consolidated financial statements in our audit report dated February 27, 2026. The consolidated statement of financial position as at December 31, 2025, presented herein for comparative purposes, is consistent, in all material respects, with the above audited consolidated statement of financial position as at December 31, 2025.

Review standards and their application in practice vary among countries. The procedures and practices used in the Republic of Korea to review such financial statements may differ from those generally accepted and applied in other countries.
