  2. 2

    Combined controlling-interest net income over the most recent four quarters (3Q2025-2Q2026) reached KRW 71.3 billion, showing a quarter-by-quarter improvement pattern.

  3. 3

    The company was the first to develop and now exclusively supplies the non-emissive material Black PDL, with adoption expanding alongside the spread of CoE technology.

  4. 4

    The company is pursuing localization of the semiconductor material PSPI, with brokerage analysis pointing to potential mass production visibility in 2026.

  5. 5

    The debt ratio rose sharply to 51.8% in 2025 from 13.4% in 2024, reflecting changes in the consolidated financial structure following the subsidiary's inclusion.

02

Business structure

Duksan Neolux is a materials company that develops and manufactures organic materials for OLED displays in-house, with core products including emissive materials such as HTL, Red Host, Red Prime, G Prime, and Blue Prime, as well as the non-emissive material Black PDL.

Black PDL, which the company was the first in the world to develop and mass-produce, is a key material that improves OLED display uniformity and is supplied on an exclusive basis. Its primary customer is Samsung Display, with materials being supplied for flagship smartphones including the Galaxy S26 series.

As of around August 2025, revenue mix was reported at roughly 72% from the display segment and about 27% from Hyundai Heavy Industries Turbomachinery, a subsidiary whose stake was recently acquired.

Hyundai Heavy Industries Turbomachinery, which supplies gas turbine compressors and nuclear power plant pumps, has been consolidated into results since the second quarter of 2025.

The company has also decided to acquire a 100% stake in S&S Valve, reportedly Korea's top maker of cryogenic valves for LNG and shipbuilding applications, with consolidation expected from the second half of the year.

In the core OLED materials business, competition within China has intensified, and the company is reportedly responding through mix improvement centered on the higher-value Black PDL.

In addition, the company is developing localized PSPI semiconductor material, which, if successful, could become a new growth pillar entering a supply chain currently led by Asahi Kasei, HD MicroSystems, and Sumitomo Chemical.

Earnings analysis

Consolidated revenue in 2025 reached KRW 344.3 billion, up 62.3% from KRW 212.3 billion in 2024, a jump largely attributable to the consolidation effect of Hyundai Heavy Industries Turbomachinery.

However, operating profit grew only 15.8% to KRW 60.7 billion from KRW 52.5 billion, pushing the operating margin down to 17.6% from 24.7% in 2024. Controlling-interest net income rose 16.3% to KRW 53.2 billion from KRW 45.8 billion.

Looking back to 2022, operating margin moved from 25.4% in 2022 to 20.1% in 2023, 24.7% in 2024, and 17.6% in 2025, reflecting shifts in business mix.

On a quarterly basis, revenue and profit expanded together from KRW 80.9 billion revenue and KRW 10.3 billion operating profit (about 12.7% margin) in 2Q2025, to KRW 98.3 billion and KRW 17.5 billion (17.8%) in 3Q2025, and KRW 127.1 billion and KRW 23.1 billion (18.1%) in 4Q2025.

In 1Q2026, revenue fell sharply to KRW 72.9 billion quarter-over-quarter, yet operating profit reached KRW 17.1 billion, lifting the operating margin to 23.5%, suggesting that the share of higher-value products held up despite seasonal weakness.

In 2Q2026, revenue rebounded to KRW 94.6 billion, with operating profit of KRW 18.5 billion and controlling-interest net income of KRW 19.5 billion, up from KRW 16.1 billion in the prior quarter, extending the improving trend.

The combined controlling-interest net income over the most recent four quarters (3Q2025-2Q2026) totaled KRW 71.3 billion, supporting an annualized recovery trajectory.

The sharp rise in the 2025 debt ratio to 51.8% from 13.4% in 2024 appears to reflect changes in the consolidated financial structure following the subsidiary's inclusion, with consolidated liabilities rising to KRW 243.7 billion from KRW 53.3 billion.

Industry analysis

The OLED materials industry appears to be shifting from a smartphone-centric cycle toward two additional growth axes: expanded adoption in IT devices such as laptops and tablets, and growth in the foldable phone market.

One brokerage noted that a North American customer plans to adopt OLED in laptops and tablets in 2026. On the other hand, concerns over smartphone sales slowing amid a memory semiconductor supply shortage have reportedly reduced overall market attention to the components and materials sector.

Analysis indicated that major Chinese smartphone makers such as Xiaomi and Transsion have reportedly lowered their 2026 shipment plans due to memory supply instability. By contrast, Samsung Electronics and Apple are seen as maintaining sales momentum on relatively stable component supply.

In terms of competitive positioning, analysis points to low-price competition among Chinese OLED material makers as a headwind to core business revenue growth, while Duksan Neolux is seen responding through its exclusive supply position in higher-value materials such as Black PDL.

In the foldable smartphone market, adoption of color-filter-on-encapsulation (CoE) technology is reportedly expanding, a structure that incorporates Black PDL in place of a polarizer, directly tying into the company's positioning according to brokerage analysis.

06

Outlook

A number of brokerages have projected that earnings improvement will become more pronounced from the second half of 2026. One brokerage projected that earnings improvement would become clearly visible from the second half, driven by new form-factor revenue contribution and expanded Black PDL adoption.

Another brokerage forecast that solid earnings momentum would continue as new materials such as PSPI begin to contribute.

Analysis suggested that localization of the semiconductor material PSPI could see mass production visibility in 2026, and given that major existing suppliers include Asahi Kasei, HD MicroSystems, and Sumitomo Chemical, successful entry could represent a shift in the existing supply chain structure.

Analysis also noted steadily increasing new orders for subsidiary Hyundai Heavy Industries Turbomachinery, centered on nuclear power plant pumps and gas compressors, and further subsidiary-level revenue growth could occur if the S&S Valve stake acquisition is reflected in consolidated results from the second half.

Reports have indicated an expected launch of a foldable iPhone and the iPhone 18 around September 2026, making post-launch initial sales trends and material supply volumes a key point to monitor.

These outlooks, however, remain brokerage estimates and should be treated as provisional information until superseded by the company's official guidance or confirmed disclosures.

On valuation, analysis has suggested that despite the recent earnings recovery, market attention has been drawn toward leading sectors such as semiconductors and secondary batteries, leaving the stock relatively overlooked.

One brokerage assessed in a report dated June 10, 2026 that the stock was trading at a multiple below its five-year average based on 2026 estimated earnings at the time.

On price targets, iM Securities set a target of KRW 70,000 in a report dated June 10, 2026, Kyobo Securities raised its target to KRW 60,000 in a report dated May 22, 2026, and BNK Investment & Securities raised its target to KRW 66,000 in a report dated May 13, 2026 — though these reflect each firm's own judgment and are subject to change over time.

On dividends, it is confirmed that the company does not disclose a separate shareholder return policy. The simultaneous increase in net assets and debt ratio following the subsidiary's consolidation also suggests the financial structure is becoming more complex compared to a pure materials company.

Bull factors

Black PDL Exclusive Supply and CoE Expansion

Duksan Neolux exclusively supplies the world-first non-emissive material Black PDL, which is directly tied to the expanding adoption of color-filter-on-encapsulation (CoE) technology.

It is already supplied for flagship models such as the Galaxy S26 series, with analysis pointing to further expansion into foldable and IT devices. A growing share of higher-value products could contribute to margin defense through mix improvement.

Portfolio Diversification via Subsidiaries

The consolidation of Hyundai Heavy Industries Turbomachinery added industrial revenue from nuclear power plant pumps and gas turbine compressors, and the company has reportedly decided to acquire a stake in S&S Valve, Korea's leading cryogenic valve maker.

This could diversify revenue sources beyond a single OLED materials business. Analysis has also pointed to solid demand in nuclear power and LNG-related industrial equipment.

New Material Pipeline (PSPI)

Localization of the semiconductor material PSPI is under development, and analysis suggests that if successful, it could become a new growth pillar entering an existing supply chain led by Asahi Kasei, HD MicroSystems, and Sumitomo Chemical.

With mass production visibility projected for 2026, this warrants observation as an additional axis of business diversification.

09

Bear factors

Intensifying Competition in China

Analysis has noted that revenue in the core OLED materials business was somewhat sluggish due to intensifying competition within China. If low-price competition persists, core business revenue growth could be constrained, and mix improvement toward higher-value products may not fully offset this.

Financial Structure Complexity and Rising Debt Ratio

The debt ratio rose sharply to 51.8% in 2025 from 13.4% in 2024, interpreted as a result of changes in the consolidated financial structure following the subsidiary's inclusion.

Given the plant-project nature of the industrial subsidiary's business, quarterly revenue and profit volatility may follow a different pattern from the core business, potentially reducing the predictability of consolidated results.

End-Demand Uncertainty in Smartphones

Analysis suggests that some smartphone makers experienced production disruptions amid rising memory semiconductor prices and supply concerns. If Chinese makers continue to lower shipment volumes, stable demand centered on Samsung and Apple alone may not fully offset a broader slowdown in the front-end industry.

10

Risk factors

Customer and Demand Concentration Risk

A significant portion of revenue is tied to smartphone and display demand from a small number of major customers, including Samsung Display. Delays or weak sales in a specific customer's new product launch could directly affect earnings.

Rumors of a delayed Apple foldable product launch have been cited as an example illustrating this concentration risk.

Subsidiary Integration Risk

There is a possibility of contingent liabilities or one-off costs arising during the integration process of industrial subsidiaries such as Hyundai Heavy Industries Turbomachinery and the pending acquisition of S&S Valve.

In the fourth quarter of 2025, approximately KRW 8-9 billion in one-off costs related to employee welfare, building maintenance, and depreciation were reflected, causing operating profit to fall short of market expectations.

Raw Material, Foreign Exchange, and Macro Risk

Analysis has noted that rising memory semiconductor prices could increase cost burdens for smartphone set makers, potentially affecting front-end demand.

In addition, a market environment where domestic equity funds concentrate on specific leading sectors such as semiconductors and secondary batteries has been cited as a factor that can affect investment sentiment toward small and mid-cap materials stocks broadly.

12

Overall view

Duksan Neolux has seen significant top-line expansion as structural growth in its OLED emissive and non-emissive materials business combined with the consolidation effect of an industrial subsidiary, while operating margin has fluctuated amid the shifting business mix.

Annual revenue rose 62.3% year-over-year in 2025, but operating margin declined to 17.6% and the debt ratio rose sharply to 51.8%, reflecting a more complex financial structure.

Combined controlling-interest net income over the most recent four quarters reached KRW 71.3 billion, supported by a quarter-by-quarter improvement trend, with the exclusive supply position in Black PDL and the spread of CoE technology cited as key growth drivers.

On the other hand, intensifying competition within China, uncertainty in end-demand for smartphones, and subsidiary integration risk are factors that warrant balanced consideration.

Brokerages have issued a series of upward target price revisions, though these reflect each firm's own judgment and are subject to change over time.

Going forward, the launch of Apple's foldable new product, third-quarter earnings, the effect of subsidiary consolidation, and progress on PSPI mass production remain the key points to monitor.
