Structural Turnaround of HD Hyundai Energy Solutions – Transitioning from a Solar Module Manufacturer to a Global Energy Solutions Company

Executive Summary – HD Hyundai Energy Solutions at the Dawn of Structural Change

HD Hyundai Energy Solutions (HES), a leading renewable energy company in Korea, is showcasing remarkable changes in 2025. This Ulsan-based company, which faced challenges due to the plummeting module prices from China and a sluggish domestic market until 2024, achieved an operating profit margin of 10.1% on a cumulative basis as of the third quarter of 2025, earning praise for its successful transformation. This figure represents an approximately fourfold increase from 2.7% in the same period last year, achieved despite a 3.9% decrease in sales to 331.4 billion KRW.

The changes at HD Hyundai Energy Solutions are interpreted as a structural transition beyond mere performance improvement. The company is visibly transforming from a solar module manufacturing focus to a comprehensive energy solutions company encompassing PCS (Power Conditioning System) inverters, ESS (Energy Storage System), EPC (Engineering, Procurement, Construction), and O&M (Operation & Maintenance). Notably, the overseas sales ratio has expanded to 36%, reducing domestic dependence while successfully differentiating from Chinese companies through the advancement of a product portfolio centered on high-efficiency N-Type modules.

In terms of financial stability, HD Hyundai Energy Solutions demonstrates industry-leading soundness. A debt ratio of 24.5% and a net cash structure (cash assets of 68 billion KRW, borrowings of 17.3 billion KRW) are rare financial structures in the highly volatile solar industry. An interest coverage ratio of 124 times suggests a near debt-free company, indicating ample capacity for large-scale investments or dividend resumption in the future.

As of November 2025, the global solar market is experiencing contrasting trends of intensified price competition due to oversupply from China and strengthened energy security policies in various countries. Policies such as the U.S. Inflation Reduction Act (IRA), Europe’s REPowerEU plan, and Japan’s Green Transformation (GX) policy are providing new opportunities for Korean companies, and HD Hyundai Energy Solutions is actively leveraging these policy benefits.

Business Structure Analysis and Strategic Positioning

The current business structure of HD Hyundai Energy Solutions shows that solar modules account for 73% of sales, PCS inverters and control systems make up 18%, order-based installation (Solar EPC) business constitutes 7.5%, and O&M and other solutions comprise 1%. This composition indicates a shift from two years ago, with a decrease in module proportion and an increase in solution proportion, clearly demonstrating the company’s strategic direction.

From a production base perspective, while maintaining a direct production system for cells and modules centered on the Eumseong plant in Chungbuk, the company is securing cost competitiveness and production flexibility through partnerships with global Tier-1 manufacturers. Particularly, investments in research and development through the Global R&D Center (GRC) are leading to efficiency improvements in N-Type modules and the development of next-generation technologies, serving as a technical differentiation factor from Chinese companies.

In comparison with competitors, HD Hyundai Energy Solutions’ unique position is evident. Hanwha Solutions focuses on maximizing IRA benefits through local production in the U.S., while global leaders like China’s LONGi Solar and JinkoSolar rely on cost competitiveness through economies of scale. In contrast, HD Hyundai Energy Solutions is building a differentiated value proposition by enhancing system integration capabilities beyond being a mere module supplier.

The growth of the PCS business is particularly noteworthy. It has shown steady growth from 55.5 billion KRW in 2023 to 74 billion KRW in 2024, and 61.1 billion KRW on a cumulative basis as of the third quarter of 2025, reflecting the increasing demand for grid connection and control systems for solar power plants. The global PCS market is growing at an annual rate of 10-15%, and despite strong competitors like China’s Sungrow and Huawei, HD Hyundai Energy Solutions is accelerating its overseas expansion based on high market share and technological prowess in the domestic market.

The technological transition to N-Type modules is a key factor determining the future competitiveness of HD Hyundai Energy Solutions. The shift to TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction) technologies, which offer higher efficiency and better temperature coefficients compared to existing PERC technology, is accelerating globally, and HD Hyundai Energy Solutions is actively responding to this trend. N-Type modules can secure a technological edge over Chinese companies and enhance competitiveness in the premium market.

The strategy for expanding overseas markets targets the U.S. and Europe as key areas. In the U.S., solar projects are increasing due to IRA benefits, with a growing preference for Korean-made modules, especially in commercial and utility-scale projects. In Europe, the combination of renewable energy expansion policies under the REPowerEU plan and the need for supply chain diversification away from Chinese products is providing opportunities for Korean companies. The Australian market also presents a favorable environment for HD Hyundai Energy Solutions due to the increase in large-scale solar projects and the market’s emphasis on quality.

The expansion of system integration and EPC business is evaluated as a long-term growth driver for HD Hyundai Energy Solutions. The ability to provide one-stop solutions encompassing design, procurement, construction, and operation beyond simple module supply allows customers to achieve risk reduction and efficiency enhancement simultaneously. Particularly, the O&M business offers a recurring revenue structure lasting 20-25 years, enhancing the stability and predictability of sales.

Financial Performance Analysis and Investment Outlook

The financial performance of HD Hyundai Energy Solutions in the third quarter of 2025 is filled with indicators proving the success of structural changes. Sales of 331.4 billion KRW decreased by 3.9% compared to the same period last year, but the operating profit margin improved significantly from 2.7% to 10.1%, and net profit turned positive to 29.1 billion KRW from a loss of 11.3 billion KRW last year. This performance is interpreted as the result of a management strategy focusing on profitability and efficiency rather than sales scale.

The most notable point in the change of sales structure is the increase in the proportion of overseas sales. Export sales reached 123 billion KRW, accounting for 36% of total sales, which is a strategic achievement in reducing dependence on the domestic market and strengthening the position in the global market. Domestic sales decreased to 216.9 billion KRW from 308.3 billion KRW last year, reflecting the structural downturn of the domestic solar market, but the successful transition to overseas markets offsets this.

The improvement in cost structure is a key indicator showing the increase in management efficiency at HD Hyundai Energy Solutions. The reversal of inventory valuation allowances due to the collapse of global cell and module prices, defense of selling prices through an increase in the proportion of high-efficiency modules, a decrease in logistics and raw material costs, and a reduction in depreciation collectively improved the cost ratio significantly. Particularly, the limitation of the average selling price (ASP) decline due to the increase in the proportion of overseas sales suggests that the differentiation strategy from low-cost Chinese products is succeeding.

In terms of financial stability, HD Hyundai Energy Solutions maintains a top-tier level in the industry. A debt ratio of 24.5% is very low compared to typical manufacturing industries, and considering cash assets of 68 billion KRW and borrowings of 17.3 billion KRW, it can be considered a net cash company. An interest coverage ratio of 124 times shows ample financial leeway, indicating sufficient capacity for large-scale capital investments, mergers and acquisitions, or dividend resumption.

The possibility of dividend resumption is one of the main investment attractions of HD Hyundai Energy Solutions. According to the company’s dividend policy, more than 30% of net profit is to be paid as dividends, and based on the 2025 net profit of 29.1 billion KRW, a dividend of about 8.7 billion KRW, or 780 KRW per share, is possible. At the current stock price level, a dividend yield of about 1.5-2% is expected, and if performance improvement continues, the dividend scale may also expand.

The CAPEX investment status shows that HD Hyundai Energy Solutions is actively investing in future growth. The increase in assets under construction, execution of capital investments, and the flow of replacement of tangible assets are interpreted as forward deployment for production expansion in 2026-2027. Particularly, focused investments in expanding N-Type module production capacity and PCS manufacturing facilities are expected to increase the proportion of high-value-added products and sales growth in the future.

From a valuation perspective, the dominant analysis is that HD Hyundai Energy Solutions is currently in an undervalued range. A PBR of 0.7-0.9 times is considered attractive given the capital-intensive nature of the manufacturing industry, and if performance improvement continues, a revaluation to 1.0-1.2 times is possible. In terms of PER, considering the current trend of performance improvement, it is trading at a reasonable level, making it an attractive entry point from a mid- to long-term investment perspective.

Risk factors include the continued downturn of the domestic market, intensified price competition with Chinese companies, lack of predictability due to a decrease in order backlog, volatility in the solar industry, and intensified competition in the PCS market. Particularly, if China’s oversupply continues, there may be additional downward pressure on module prices, which could negatively impact sales and profitability. However, HD Hyundai Energy Solutions’ strong financial structure and differentiated product portfolio provide a significant defense against these risks.

Opportunity factors include the expansion of the high-efficiency N-Type market, benefits from IRA and EU policies, investment capacity based on financial stability, expansion of O&M and solution businesses, and the possibility of dividend resumption. Particularly, the acceleration of the global energy transition and the strengthening of energy security policies in various countries create a favorable environment for Korean companies in the mid- to long-term, and HD Hyundai Energy Solutions possesses the capabilities and resources to actively leverage these opportunities.

In conclusion, HD Hyundai Energy Solutions is currently in the early stages of a structural turnaround, with short-term expectations for performance improvement and dividend resumption, and mid- to long-term growth through global market expansion and solution business enhancement. As it passes through the bottom of the solar industry’s cycle and transforms from a low-profit manufacturing company to a high-efficiency, solution-oriented company, it is on an upward trajectory in terms of profitability, finance, product strength, and strategy, making it an investment target expected to be re-evaluated in 2026-2027.
