● A 19-year tradition since 2008; CEO Jong-woo Kim and key executives join this year’s volunteering

●​ "We will continue to fulfill our corporate social responsibility based on our well-established volunteer culture."

SKC (CEO Jong-woo Kim) announced today that it conducted a cemetery cleansing activity, including placing Korean national flags (Taegeukgi), at the National Cemetery in Seoul to pay tribute to fallen heroes ahead of the 71st Memorial Day.

Key executives, including CEO Jong-woo Kim and CFO Dong-ju Park, visited the site to participate in the activities alongside employees. The volunteer group began by observing a moment of silence at the Memorial Tower for patriotic martyrs and fallen heroes. They then moved to Cemetery No. 19, which honors 913 fallen soldiers and officers, to plant national flags, pull weeds, and wipe down tombstones.

SKC’s cemetery cleansing activity is not a one-off event but part of a deeply rooted corporate volunteer culture. Following the launch of its volunteer group in 2004, SKC established a sisterhood relationship with the Seoul National Cemetery in 2008 and has continued this initiative for 19 consecutive years.

An SKC official stated, "Through this activity, where management and employees came together, we were able to once again honor the sacrifices of our patriotic martyrs.

• Final offering price set at 99,500 KRW, issuing 11.73 million shares to raise 1.1671 trillion KRW

• Increased proceeds to expand debt repayment; Debt-to-equity ratio projected to drop sharply from 230% to 129%

• Market confidence bolstered by Q1 turnaround and U.S. IR activities; Focus on progress in next-gen glass substrate commercialization

SEOUL, South Korea – SKC (CEO Kim Jong-woo) is set to accelerate investment in its core future business, glass substrates, while significantly improving its financial structure through a rights offering totaling 1.1671 trillion KRW.

On the 12th, SKC announced that the final issuance price for the rights offering was confirmed at 99,500 KRW. Consequently, SKC will issue 11.73 million new shares to raise a total of 1.1671 trillion KRW. The market expects this capital injection to serve as powerful momentum for securing future growth engines and establishing financial stability.

The funds secured through this offering will be strategically utilized for new business investments and strengthening financial soundness. Initially, SKC planned to allocate approximately 590 billion KRW to the glass substrate business and 410 billion KRW to debt repayment. However, as the total proceeds increased due to a rise in stock price, the capacity for debt repayment expanded significantly. Since the investment for glass substrates—set at 589.6 billion KRW—proactively covers the maximum capital required for the next three years, the company plans to use the excess proceeds to increase the scale of debt repayment.

As a result, the improvement in key financial indicators, such as the debt-to-equity ratio, is expected to be maximized. While the ratio was projected to be in the low 140% range if 410 billion KRW were repaid, the increased repayment of 577.5 billion KRW is expected to drastically lower the ratio from approximately 230% at the end of last year to around 129%. This allows the company to preemptively reduce interest expenses amid high-interest rates while simultaneously bolstering internal stability and growth.

The backdrop of this increased funding lies in the recovery of SKC's fundamental competitiveness and proactive communication by management. Despite short-term stock price adjustments in March due to external factors like geopolitical risks in the Middle East, the company signaled a clear performance turnaround in its recent Q1 earnings report, achieving a positive EBITDA of 10 billion KRW for the first time in 10 quarters.

Furthermore, the recent global Investor Relations (IR) tour held for institutional investors in four cities, including New York, proved effective. Led by CEO Kim Jong-woo, the management actively communicated plans for profitability recovery, semiconductor-centered business restructuring, and glass substrate progress, successfully building firm market trust and consensus on the company’s strategic direction.

The progress in commercializing glass substrates by Absolics, an SKC subsidiary, also played a decisive role in the stock price rebound. Absolics recently launched a new project by supplying prototypes of next-generation "non-embedding" glass substrates for network semiconductors to a U.S. telecommunications chipmaker.

Designed to significantly enhance performance in high-frequency and high-density environments compared to conventional substrates, the product is currently showing tangible results in the client's reliability evaluations. If it passes, mass production preparations could begin as early as the end of this year, further raising market expectations.

An SKC official stated, "This result is a testament to the deep resonance among shareholders and investors regarding SKC’s fundamental competitive recovery and the future value of our next-generation glass substrate business. With the secured funds, we will ensure the seamless commercialization of glass substrates and accelerate our 'Stability, Recovery, and Leap' strategy through groundbreaking financial restructuring."

Meanwhile, the subscription for existing shareholders will take place on May 14 and 15, with the new shares scheduled to be listed on June 8. [End]

● Annual financial results announced on the 5th… External growth trend as revenue from core businesses rises

● Secondary battery material revenue rises toward North America… Semiconductor material business achieves record-high annual performance

● New CEO with semiconductor expertise recruited for Absolics… Aiming for phased progress by consolidating professional capabilities

SKC announced on the 5th that it recorded consolidated annual revenue of 1.84 trillion won and an operating loss of 305 billion won for 2025. Despite the changing market environment, revenue from core businesses has risen for two consecutive years, continuing the trend of external growth.

Looking at each business segment, the secondary battery material business established itself as a new growth engine, with sales of copper foil for North American ESS (Energy Storage System) surging by 133% compared to the previous year. In addition, sales of copper foil for electric vehicles also increased by 61% annually due to expanded demand following the expansion of major customers' US plants.

The semiconductor material business achieved record-high annual performance thanks to the demand for high-value-added products for AI data centers. In particular, the operating profit in the fourth quarter rose by 25.9% compared to the previous quarter, continuing the high-growth trend. The glass substrate business being conducted at the Georgia plant in the US achieved results in securing positive feedback from customers as a result of prototype simulation evaluations.

However, in the fourth quarter, one-time expenses of 316.6 billion won, such as impairment of tangible assets for the purpose of process efficiency in the secondary battery and chemical businesses, were reflected, leading to an expanded pre-tax loss. However, SKC believes it will be able to alleviate the burden of fixed costs in the future through preemptive asset restructuring.

Efforts to strengthen financial soundness along with asset structure improvement are also prominent. SKC has focused on liquidity management by securing a total of 893.3 billion won in cash annually through the issuance of perpetual exchangeable bonds (EB) and asset securitization of non-core businesses.

SKC plans to focus on profit recovery and enhancing financial stability through profitability-centered business operations this year. It plans to strengthen the management system centered on financial stamina and liquidity management until a complete profit turnaround and the full settlement of the glass substrate business.

The secondary battery material business will focus on operational efficiency based on the full-scale operation of the Malaysia plant and plans to raise annual sales by approximately 50% compared to the previous year in response to the expansion of global core customers' North American production bases.

The semiconductor material business will continue high growth of more than 20% compared to the previous year due to the continuous expansion of demand for AI data centers, and at the same time, it plans to promote the expansion of its product portfolio through joint development with customers and the expansion of production capacity in Vietnam.

The glass substrate business puts weight on enhancing execution. At the end of last year, SKC appointed CEO Kang Ji-ho, an expert from Intel and SK Hynix, and is accelerating the execution speed as an overwhelming front-runner by consolidating professional engineering capabilities. In particular, this year, it plans to make step-by-step progress through reliability tests with customers. SKC believes that glass substrates will become a 'game changer' in the semiconductor ecosystem and judges that it will be able to maintain a clear differentiation and technical gap with latecomers by aiming for high-value-added high-end product development.

An SKC official said, "Along with short-term performance management, we will closely examine the overall business structure and cost/expense structure from a more fundamental perspective," and "We will do our best to prepare a sustainable growth foundation so that we can continue our mid-to-long-term growth story."
