Fundamental View
AS OF 29 Aug 2025We have an Outperform recommendation on SK Hynix. In our view, we think its likely for the BBB2 rating on HYUELE to be upgraded to BBB1 over the next 12 months by all three agencies, as we expect its debt metrics to further improve on strong HBM shipments and for the company maintain its technological and market share leadership. HYUELE currently trades an average 7 bp wider than Asia BBB+ corp, and we expect spreads of HYUELE to tighten towards Asia BBB+ corps as it credit metrics further improves over the next 12 months. Compared to US tech memory chip peer Micron, SK Hynix trades largely in-line which we view as attractive given the higher ratings of HYUELE. We like the HYUELE 6.50% 2033 bond in particular.

Risk & Catalysts
AS OF 29 Aug 2025The memory sector is subjected to significant boom/bust cycles, leading to volatility in its revenue and EBITDA margin. During an upcycle, memory vendors typically expand capacity to meet strong end-demand from PC, smartphones, and servers; however, the long-lead time for new plants could result in an oversupply when end-demand is tapering off.
Capex intensity (as % of revenues) and R&D costs are elevated even in downcycles for SK Hynix, as it needs to maintain technological leadership and fast evolving product requirements from customers.
SK Hynix has large production and revenue exposure to China; rising US-China tension and restrictive US chip exports to China could destabilize the long-term prospect of its China production and weigh on its $ bonds. Though, in Oct-23 SK Hynix was designated as a “Validated End User” by the US government, which gave it an indefinite waiver for importing US chip gears to their Chinese plants.
SK Hynix may be vulnerable to US tariff risk; the company derived 73% of 1Q25 revenues from the US.

CreditSight View Comment
AS OF 04 Sep 2025We maintain our O/P recommendation on HYUELE as we do not expect the company to be materially affected by the loss of its VEU waiver over the next 18 months. We retain our view that it is likely for the BBB2 rating on HYUELE to be upgraded to BBB1 over the next 12 months by all three agencies, as we expect its debt metrics to further improve on strong HBM shipments and for the company maintain its technological and market share leadership. HYUELE currently trades marginally wider than Asia BBB+ corporate, and we expect spreads of SK Hynix to tighten towards its Asia BBB+ corp peers as it credit metrics further improves over the next 12 months We like the HYUELE 6.50% 2033 bond in particular for duration extension and a higher spread pick up of 10 bp against Asia BBB+ corporates.
