As the semiconductor industry emerges from a downturn, SK Hynix’s performance has steadily improved over the past few quarters. Now, let’s take a closer look at the latest financial results and what they implications for bond investors.
Global Demand Recovery and AI Boom boost SK Hynix’s Performance
In 2022 and 2023, the global semiconductor market, especially memory products like DRAM and NAND faced significant challenges. Weak global demand and excess inventory led to sharp declines in demand for these products, causing prices to fall and plunging the entire industry into a severe downturn. SK Hynix was no exception, and its performance was heavily impacted. However, as the market gradually absorbed excess inventory and demand recovered, alongside the rapid development of AI technology, particularly in data centers and high-performance computing, demand for high-end memory products surged, driving a notable rebound in SK Hynix's performance.
Currently, with the sustained growth in AI demand, SK Hynix’s high-value products are once again in the spotlight. In the HBM sector, the company has become an essential part of the supply chain for top-tier processors such as NVIDIA’s. This trend is expected to continue driving the company's growth, helping it better navigate industry cycles.
SK Hynix anticipates that as generative AI technology develops further and global tech giants increase their investments in artificial general intelligence, demand for AI memory will continue to grow. The company also forecasts that demand in the PC and mobile device markets will gradually recover next year.
In the DRAM sector, SK Hynix is accelerating the transition from HBM3 (fourth-generation) to the more advanced 8-layer HBM3E and plans to begin supplying 12-layer HBM3E (fifth-generation) in Q4. HBM products currently account for 30% of the company’s DRAM revenue, and SK Hynix expects this to rise to 40% by Q4. In the NAND sector, the company will continue expanding sales of high-capacity eSSDs and focus on improving investment efficiency and optimizing production.
SK Hynix has capitalized on the growing demand for AI and high-performance computing, surpassing Samsung
SK Hynix has become one of the leaders in the global high-end memory market, thanks to its agility and market foresight. Mr. Lu Chih-yuan, President of Macronix (a leading integrated device manufacturer in the Non-Volatile Memory market), mentioned “Although the concept of stacking memory (a multi-layer memory chip technology) was proposed decades ago, it did not become a focus of the industry due to insufficient demand.” However, with the rise of AI technology, demand for high-performance computing has surged, particularly in data centers and graphics processing units (GPUs), leading to strong demand for HBM, and SK Hynix successfully capitalized on this opportunity.
In contrast, Samsung has been slow in developing and marketing its HBM products. Samsung’s HBM products are still in the testing phase and face several challenges, which has caused the company to lose its edge in the market. Meanwhile, SK Hynix and Micron have already started mass production and sale of HBM products, leading to a decline in Samsung’s market share. This lag is also reflected in their stock prices—Samsung’s stock has dropped by over 20% year-to-date.
In contrast, Samsung has been slow in the development and market promotion of its HBM products. Samsung’s HBM products are still in the testing phase and are facing several engineering challenges, causing the company to lose its competitive edge in the market. Meanwhile, SK Hynix and Micron have already started mass production and sales of HBM products, resulting in Samsung gradually falling behind in this segment.
On the other hand, SK Hynix, as a primary HBM memory supplier to NVIDIA, has strengthened its market advantage, pushing its stock price up by over 30% year-to-date. This clearly demonstrates that SK Hynix is better positioned than Samsung in capturing market demand and responding quickly to technological trends.
Additionally, SK Hynix has further adjusted its business structure by reducing its focus on wafer foundry and CMOS Image Sensors (CIS) businesses and concentrating on high-margin products. The company is also actively expanding into emerging technology areas, including Compute Express Link, Processing In Memory (PIM), and AI solid-state drives (AI SSDs), to meet the demand for next-generation memory solutions. With its flexible market strategies, technological leadership, and focus on high-value products, SK Hynix is expected to maintain strong competitiveness in the years ahead and continue solidifying its leadership position in the global high-end memory market.
Clear Signs of Downturn Ending, SK Hynix’s Strong Recovery
SK Hynix’s performance has shown a strong rebound (see Chart 1), with revenue on a steady upward trend, driven by surging demand for high-end products. In Q3 2024, the company’s revenue reached KRW 17.6 trillion, marking a historical high and a 93% increase compared to the same period last year.
Breaking down by products, DRAM remains the company’s primary revenue driver, accounting for 69% of total revenue, while NAND contributes 28%. As demand for AI and high-performance computing continues to rise, we anticipate further growth in DRAM and NAND sales, which will further drive the company’s overall revenue

The company’s profitability (see Chart 2) also showed a strong recovery in Q3 2024. EBITDA surged to KRW 10.1 trillion, representing a 496% year-on-year increase, with EBITDA margin rising to 57%, far exceeding the previous year’s figures. This further confirms the significant growth in SK Hynix’s profitability, driven by recovering market demand and strong sales of core products.

SK Hynix’s financial position continues to strengthen, with a sharp reduction in leverage
As of the end of September 2024, SK Hynix’s financial position continues to strengthen. Thanks to strong profit growth and the effective use of operating cash flow for debt repayment, the company’s total debt decreased to KRW 21.8 trillion, while its net debt ratio dropped from 38% in 2023 to 17% in 2024, reflecting a notable reduction in leverage.
Despite ongoing large-scale investments to drive corporate growth and technological innovation, the company’s financial structure continues to improve. This demonstrates SK Hynix’s ability to pursue both growth and financial health simultaneously.
With central banks raising interest rates globally, SK Hynix issued several bonds in the first half of 2023, which led to a sharp rise in its average financing cost, further increasing to 5.7% in 2024. However, the company’s strong profit growth and improved cash flow enabled it to manage these higher financing costs. At the same time, SK Hynix’s interest coverage ratio continued to rise significantly, from 4.0x in 2023 to 18.9x in 2024. This indicates that the company has maintained strong debt repayment capacity and further strengthened its financial health while reducing leverage.
Table 1: SK Hynix Credit Metrics
| (KRW Trillions) | End of 2022 | End of 2023 | September 2024 |
| Cash & Cash Equivalent | 6.4 | 8.9 | 10.9 |
| Total Debt | 23.9 | 29.5 | 21.8 |
| Net Gearing Ratio (x) | 26% | 38% | 17% |
| Net Debt/EBITDA (x) | 0.8 | 3.5 | 0.4 |
| Interest Coverage Ratio (x) | 39.3 | 4.0 | 18.9 |
| Cost of Borrowing (%) | 2.3% | 5.0% | 5.7% |

Given the highly cyclical nature of the semiconductor industry, we conducted a stress test on SK Hynix’s debt repayment capacity to simulate whether the company can maintain its solid debt repayment ability during industry downturns. Using the 2024 EBITDA of KRW 28.7 trillion as a baseline and referencing the 2023 industry low of KRW 5.9 trillion in EBITDA, we estimated the company’s net debt/EBITDA and interest coverage ratios under different levels.
| EBITDA Level (KRW Trillions) | Net Debt/EBITDA (x) | Interest Coverage Ratio (x) |
28.7 (Current Level) | 0.4 | 18.9 |
5.9 (2023 Low) | 1.9 | 3.9 |
| Source: Company’s report, iFAST Compilations Data as of 30 June 2024 | ||
If EBITDA were to decline to KRW 5.9 trillion (only 21% of the current level), SK Hynix’s net debt/EBITDA ratio would increase only to 1.9x, while its interest coverage ratio would still remain at 3.9x. This demonstrates that the company still has sufficient debt repayment capacity. Despite potential cyclical downturns, SK Hynix’s leverage remains manageable, and its debt servicing ability stays robust across different scenarios, keeping overall credit risk low.

The demand for memory products is heavily dependent on the development of consumer electronics and data centers, and fluctuations in these applications may pose risks to SK Hynix’s revenue. Additionally, the memory semiconductor industry is highly cyclical, making the company vulnerable to performance pressure when market demand declines.
Although demand for AI and data center applications drove the market recovery in 2024 and boosted the company’s performance, the global semiconductor market still faces an unstable policy environment. US government policies aimed at attracting semiconductor investments could disrupt market structures, further exacerbating industry volatility.
SK Hynix’s production and sales are heavily reliant on the Chinese market. Approximately 40%-50% of its DRAM and 20% of its NAND products are manufactured in China, and 30% of its revenue comes from the Chinese market. While US restrictions on China’s access to advanced technology have weakened Chinese competitors in the short term, further strategic measures from US and Chinese regulators pose potential threats to the company’s credit rating.
