S-oil and SK Telecom Investment Analysis Report: Current Opportunities and Risk Assessment
I. Executive Summary
This report comprehensively analyzes the investment attractiveness of S-oil and SK Telecom at the current juncture. S-oil is heavily influenced by the cyclical fluctuations of the refining and petrochemical industries and has recently experienced poor performance. However, long-term corporate value appreciation is expected, driven by business portfolio diversification through the large-scale Shaheen Project and a projected recovery in refining margins. While a change in dividend policy is anticipated in the short term, this can be interpreted as an investment for future growth.
SK Telecom, built on stable wireless and wired communication businesses, is actively fostering artificial intelligence (AI) and cloud businesses as new growth engines. Despite challenges such as saturation in the traditional telecommunications market and regulatory changes, the company is evaluated as pursuing both stability and growth through tangible results in its AI business and a consistent dividend policy.
Overall, S-oil, considering its current undervalued status and the potential for future business transformation, could be a buying opportunity from a long-term perspective, but it requires tolerance for short-term volatility and project risks. SK Telecom, on the other hand, offers balanced investment appeal based on stable cash flow and the growth of its AI business, making it suitable for investors seeking steady returns and future growth drivers with relatively lower risk.
II. Introduction
This investment analysis report aims to provide an in-depth evaluation of the current investment value of two major Korean companies: S-oil and SK Telecom. This analysis focuses on each company's recent operational and financial status, strategic direction, and market outlook from 2024 through 2025 and beyond. This report provides a detailed, data-driven assessment for sophisticated investors seeking to make informed investment decisions.
S-oil, established in 1976, is a leading Korean refiner with a diversified business portfolio including refining, petrochemicals, and lube base oil.
The current macroeconomic environment is shaped by various factors, including global economic uncertainty, dynamic changes in the energy market, and technological shifts such as AI adoption. These elements significantly impact the investment landscape for both companies, and this report will analyze each company's position within this complex environment.
III. S-oil: Investment Analysis
A. Company Overview and Business Segments
S-oil, established in 1976, is a refiner with a diversified business portfolio including refining, petrochemicals, and lube base oil.
S-oil's profitability is highly sensitive to global refining margins and crude oil price fluctuations due to the high proportion of its refining segment. This means that the company's overall profitability is significantly affected by the cyclical nature of the refining industry. However, diversification into petrochemicals and lube base oil, despite their relatively smaller scale, provides some buffer against the extreme volatility of the refining segment. In particular, strategic expansion into petrochemicals, such as the Shaheen Project, is a deliberate effort to diversify the fuel-centric refining business, with the potential to fundamentally change the company's business structure, enhance earnings stability, and create higher value in the long term.
B. Recent Financial Performance (Q1 2024-2025)
S-oil recorded negative performance in 2024, with consolidated revenue increasing by 2.5% year-on-year, but operating profit plummeting by 68.8%, leading to a net loss.
Table 1: S-oil Key Financial Indicators (Full Year 2024 and Q1 2025)
| Category | 2024 (Consolidated) | Q1 2025 (Consolidated) |
|---|---|---|
| Revenue (KRW billion) | 357,270 (Est.) | 89,905 |
| Operating Profit (KRW billion) | 4,220 (Est.) | -215 (Deficit) |
| Net Income (KRW billion) | -1,930 (Est.) | -446 (Deficit) |
Looking at the Q1 2025 performance by business segment, the refining segment showed weakness due to China's export quotas and the influx of Middle Eastern/Indian volumes caused by Red Sea risks, but it saw some recovery due to increased winter demand and China's economic stimulus measures.
S-oil's sharp decline in operating profit in 2024 and its shift to a deficit in Q1 2025 indicate that the refining and petrochemical sectors are currently experiencing a difficult cyclical downturn. This has been exacerbated by geopolitical risks (Red Sea risks) impacting supply chains and complex dynamics in the Chinese market (new supply, export quotas). This poor performance is not merely a short-term fluctuation but signifies that the company is facing macroeconomic headwinds, which is an important backdrop for interpreting future outlooks and strategic moves.
C. Industry Outlook and Key Drivers (2025-2026 Forecast)
Despite the current high volatility, refining margins are expected to recover in 2025.
In the petrochemical market, while the PO market weakened in Q1 2025 due to new supply from China
S-oil's overall performance in 2025 is expected to show a significant recovery. Revenue is projected at KRW 30.4 trillion, operating profit at KRW 958.4 billion, and net income attributable to controlling interests at KRW 985.7 billion.
S-oil's core refining business is expected to see a strong rebound in 2025, primarily driven by a marked slowdown in global refining capacity expansion. This is a strong signal that the current downturn is cyclical, and supply-side improvements will drive future profitability. The market anticipates a shift from oversupply to a more balanced or even undersupplied state, and this change in the industrial environment is expected to have a direct positive impact on S-oil's core business.
D. Strategic Initiative: Shaheen Project
The Shaheen Project is S-oil's second-phase petrochemical expansion project, representing the largest investment in Korea's petrochemical history and the largest ever by Saudi Aramco in Korea.
Key facilities of this project include the world's largest steam cracker (1.8 million tons per year of ethylene), the TC2C facility, a new technology that directly converts crude oil into petrochemical feedstocks, and polymer facilities that produce high-value-added petrochemical products.
As of April 2025, the project is progressing smoothly with a completion rate of 65.4%
Upon completion of the Shaheen Project in 2026, S-oil's petrochemical share in its business portfolio is expected to more than double from the current 12% to 25%.
The Shaheen Project is more than just a business expansion; it is a transformative investment that fundamentally changes S-oil's business model. It is a strategic move to reduce reliance on volatile refining margins and accelerate the shift towards high-value-added petrochemical products. This strategic transformation, backed by massive investment from Saudi Aramco, is expected to be a key driver of future value creation despite current financial burdens. Investors should focus on the long-term business structure change and the potential for corporate value re-rating that this project will bring, rather than short-term financial results.
E. Dividend Policy and Sustainability
S-oil's recent dividend yield was 2.99%.
However, S-oil has lowered its dividend payout ratio target to "20% or more of net income" for the fiscal years 2025-2026.
S-oil's lowered dividend payout ratio target is a direct consequence of the large-scale capital injection into the Shaheen Project. This indicates that the company prioritizes long-term growth and business structure innovation over short-term shareholder returns. While this may reduce attractiveness for investors seeking high dividend yields in the short term, it can be seen as a necessary strategic decision for investors expecting capital gains in the long term. This suggests that S-oil's investment value is shifting from a high-dividend stock to a growth stock, and investors should understand this changed value proposition and adjust their investment strategies accordingly.
F. Analyst Consensus and Target Price (As of June 2025)
As of May 28, 2025, the analyst consensus investment opinion for S-oil is generally positive, with an average target price of KRW 71,588.
Table 2: S-oil Analyst Consensus and Target Price (As of May 28, 2025)
Investment Opinion: 5-point scale (5: Strong Buy, 4: Buy, 3: Neutral, 2: Underperform, 1: Sell)
S-oil's stock price showed a strong rebound in late May 2025, rising by 5.41%, following a 5.72% surge on May 26. This rebound occurred after the stock hit a 5-year low of KRW 50,000 during intraday trading on May 23.
The analyst consensus, particularly the claims of a "5-year cyclical bottom" and "historically low PBR," suggests that S-oil may currently offer a contrarian investment opportunity. The market might be excessively discounting the company's value due to the current cyclical weakness and financial burden from the Shaheen Project. This implies an oversight of the long-term value creation through the Shaheen Project and the anticipated recovery in refining margins. The argument of "valuation discount" indicates that the stock is undervalued relative to its past performance and future potential. If analysts' predictions for market recovery and Shaheen Project re-rating are accurate, the current price could be a significant entry point for long-term investors willing to tolerate short-term volatility and dividend reductions.
G. Investment Considerations and Risks
Key Opportunities:
- Shaheen Project: Expected to significantly diversify the business portfolio into high-value-added petrochemicals, driving long-term growth and corporate value re-rating.
- Refining Market Recovery: Refining margins are expected to stabilize and improve in 2025 due to reduced global capacity additions.
- Undervaluation: The current stock valuation (PBR) is historically low, suggesting significant upside potential if market conditions improve and project effects become visible.
Key Risks:
- Oil Price Volatility: Continued volatility or a prolonged period of low international oil prices could negatively impact refining margins and overall profitability.
- Global Economic Uncertainty: A global economic slowdown could dampen demand for refined products and petrochemicals, hindering recovery.
- Project Execution Risk: While the Shaheen Project is progressing smoothly
- Dividend Reduction: The lowered dividend target for 2025-2026 may be unattractive to investors who prefer high dividends.
- Petrochemical Oversupply: Despite the long-term benefits of the Shaheen Project, persistent oversupply in certain petrochemical segments (e.g., PO from China) could remain a risk factor.
IV. SK Telecom: Investment Analysis
A. Company Overview and Core Businesses
SK Telecom is a leading telecommunications company in Korea, with wireless and wired communications as its core businesses.
B. Recent Financial Performance (Q1 2024-2025)
SK Telecom recorded solid performance in 2024, with consolidated revenue increasing by 1.9% year-on-year, operating profit by 4.0%, and net income by 14.3%.
In Q1 2025, consolidated revenue was KRW 4.4537 trillion, a slight decrease of 0.5% year-on-year due to the impact of subsidiary divestitures, but operating profit increased by 13.8% to KRW 567.4 billion.
Table 3: SK Telecom Key Financial Indicators (Full Year 2024 and Q1 2025)
| Category | 2024 (Consolidated) | Q1 2025 (Consolidated) |
|---|---|---|
| Revenue (KRW billion) | 179,410 (Est.) | 44,537 |
| Operating Profit (KRW billion) | 15,232 (Standalone) | 5,674 |
| Net Income (KRW billion) | 14,388 (Consolidated) | 3,616 |
| ARPU (KRW) | - | 29,239 |
The increase in operating profit in Q1 2025 is primarily attributable to the growth of the AI Data Center (AIDC) and AIX businesses.
SK Telecom's financial performance demonstrates a stable core telecommunications business, with minor revenue fluctuations attributed to portfolio adjustments (e.g., subsidiary divestitures). However, operating profit shows a clear upward trend, driven by the growth of its AI and B2B segments. This indicates successful establishment of new high-margin growth engines leveraging existing infrastructure. In a mature mobile market characterized by 5G subscriber saturation and ARPU decline, these new growth drivers are offsetting the maturity of the core business. SK Telecom is evolving beyond a telecommunications company into an AI/ICT service provider, and future growth will largely depend on the successful expansion of these new businesses.
C. Market Environment and Competition
The number of 5G subscribers is stagnant, and the pace and rate of 4G users transitioning to 5G are lower than expected, making it difficult for telecommunications companies to establish efficient management and revenue structures.
The Telecommunications Terminal Distribution Act (DanTongAct) is officially scheduled to be abolished on July 22, 2025.
Furthermore, SK Telecom experienced a cyber intrusion incident in Q1 2025. In response, the company strengthened customer protection measures, including operating a top-tier FDS (Fraud Detection System), automatically subscribing customers to SIM protection services, and offering free SIM card replacements, and established a 'Customer Trust Restoration Committee.'
SK Telecom operates in a mature domestic telecommunications market characterized by 5G subscriber saturation and ARPU decline. The abolition of the DanTongAct adds new uncertainty to the competitive landscape, potentially increasing marketing costs in the short term, but also offering opportunities for market innovation. The recent cyber security incident highlights reputational risks and demands significant resource allocation for customer trust restoration. These combined external and internal pressures emphasize that SK Telecom must skillfully manage these challenges in addition to effectively executing its AI transformation to maintain market share and profitability.
D. Growth Drivers: AI and Cloud Business
SK Telecom has declared 2025 as the "first year of AI transformation" and aims to become a global AI company.
The AI Data Center (AIDC) business recorded KRW 102 billion in revenue in Q1 2025, growing by 11.1% year-on-year, and has become a key growth engine driven by increased data center capacity and utilization rates.
Revenue from the AI Transformation (AIX) business grew by 27.2% year-on-year to KRW 45.2 billion in Q1 2025.
Expansion of AI service areas is also active. A. (A-dot) has surpassed 9 million cumulative subscribers
SK Telecom has invested approximately KRW 500 billion in AI-related businesses
SK Telecom's AI strategy goes beyond mere technology adoption, focusing on generating concrete revenue models in the B2B sector (AIDC, AIX, A. Biz). The emphasis on "AI that makes money" and the establishment of a "Korean AI ecosystem" through group synergies and strategic investments indicate a comprehensive approach to becoming a dominant AI player. The phased strategy of prioritizing A. Biz's launch within SK Group before external expansion demonstrates a cautious approach to de-risking new ventures. This suggests that SK Telecom has a well-planned strategy to capture value in the rapidly growing AI market, which could be an attractive factor for investors seeking exposure to AI growth.
E. Dividend Policy and Sustainability
SK Telecom maintains a consistent quarterly dividend policy. In Q1 2025, a dividend of KRW 830 per share was decided, with the record date set for May 31.
SK Telecom's shareholder return policy targets returning 50% or more of consolidated net income to shareholders from 2024 to 2026.
SK Telecom's commitment to maintaining a high dividend payout ratio (50% or more of net income) and consistent quarterly dividends, even amidst a significant AI transformation, demonstrates a strong dedication to shareholder returns. This indicates the company's confidence in generating sufficient free cash flow from its core telecommunications business to fund both ambitious AI investments and stable dividends simultaneously. This balanced strategy attracts and retains income-focused investors while also appealing to those interested in future growth through AI businesses. This suggests that management is confident in its financial health and strategic direction.
F. Analyst Consensus and Target Price (As of June 2025)
As of May 28, 2025, the analyst consensus opinion for SK Telecom is generally "Buy," with a 12-month target price of KRW 70,000.
Table 4: SK Telecom Analyst Consensus and Target Price (As of May 28, 2025)
FnGuide Consensus Investment Opinion is presented as BUY on a 5-point scale (5: Strong Buy, 4: Buy, 3: Neutral, 2: Underperform, 1: Sell)
The analyst consensus reflects the view that SK Telecom's stock price has temporarily declined due to short-term market volatility or specific issues (such as the cyber security incident), but its fundamentals remain robust. The assessment of "excessive short-term decline" suggests that the current stock price is undervalued relative to its intrinsic value, which could present a buying opportunity for investors. This assessment is based on confidence in SK Telecom's AI business growth potential and its stable telecommunications business foundation. Professional market evaluations allow investors to gauge SK Telecom's value and potential upside, serving as an important benchmark for making investment decisions in comparison to their own analysis.
G. Investment Considerations and Risks
Key Opportunities:
- AI Transformation: Possesses significant growth potential in AI Data Centers (AIDC), AIX, and new AI services (A. Biz, Aster), which will drive future revenue and profitability.
- Stable Core Business: The continued solid performance of traditional wireless and wired communication segments provides a stable foundation and cash flow.
- Consistent Dividends: A steady shareholder return policy offers attractive income to investors.
Key Risks:
- Regulatory Uncertainty: The abolition of the DanTongAct could intensify competition and increase marketing costs, impacting profitability.
- Intensified Competition: Beyond regulatory changes, overall intensified competition within the telecommunications market, such as 5G subscriber saturation and ARPU decline, remains a challenge.
- Cyber Security Incident: The recent security breach highlights operational risks and could impact customer trust and recovery costs.
- AI Investment Returns: The success and profitability of new AI businesses are not guaranteed and require significant ongoing investment.

- Risk Profile: Carries relatively lower risk due to stable core business, but new AI businesses involve technology and market adoption risks. Regulatory changes (DanTongAct abolition) and cyber security incidents add specific operational and competitive risks.
S-oil and SK Telecom fundamentally possess different investment characteristics. S-oil is characterized by "cyclical recovery through business transformation," representing a high-risk, high-reward investment dependent on the successful execution of large-scale capital projects and a favorable turn in commodity market cycles. In contrast, SK Telecom is an "income provider with AI growth engines," a relatively lower-risk defensive investment that seeks a balance between innovation and consistent shareholder returns while exploring new growth drivers in the technology sector. As these companies are driven by different market dynamics, holding them together can contribute to portfolio diversification.
B. General Investment Principles
- Importance of Diversification and Risk Management: Given the specific risks associated with each company (e.g., S-oil's commodity price exposure and project risk, SK Telecom's regulatory changes and AI investment uncertainty), diversification across various sectors and asset classes remains crucial.
- Long-Term vs. Short-Term Investment Horizon: S-oil's investment thesis heavily relies on the long-term success of the Shaheen Project (post-2026), so a longer investment horizon is appropriate.
- Market Volatility and Psychological Management: Investors should prepare for market volatility and avoid emotional decision-making, especially during periods of high price fluctuations. Adhering to a clear investment plan and understanding one's biases is essential.
- Consideration of Fees and Taxes: Be aware of transaction fees
- Liquidity: For large-scale investments, consider the liquidity of the stock to ensure efficient entry and exit without significant price impact.
VI. Conclusion and Recommendations
Summary of Investment Thesis
S-oil: Currently facing cyclical headwinds but is on the cusp of a major long-term business transformation through the Shaheen Project. This project is expected to fundamentally change its business composition and boost profitability from 2026 onwards. Its current valuation appears historically low, offering a potential value investment opportunity for patient investors. However, this comes with a trade-off of reduced dividends in the short term.
