Samsung Electronics and SK Hynix Set for Major Profit Surge by 2027 on Memory Supercycle

The Quick Take

• Samsung Electronics (005930) and SK Hynix (000660) are forecast for a major profit surge by 2027, fuelled by memory-chip demand from AI infrastructure build-outs.
• Both Korean chipmakers stand to benefit from the secular AI-driven upgrade cycle across HBM and DRAM, where they hold dominant global positions.
• Rising AI datacenter spending by hyperscalers is expected to underpin a multi-year earnings acceleration for Korean semiconductor majors.

Samsung Electronics and SK Hynix, the world's two largest memory chipmakers, are positioned for a major profit surge into 2027 as AI-driven demand for high-bandwidth memory (HBM) and advanced DRAM accelerates. The semiconductor sector is in an earnings-recovery phase following the 2023-24 memory downturn, and the structural tailwind from generative AI infrastructure investment is now well-established. Korea's chip industry represents roughly 20% of the country's export revenues, making this forecast a macro-economic as well as sector-specific event with broad implications for Korean equities and the won.

The profit-surge outlook carries direct implications for the global memory supply chain. Higher Samsung and SK Hynix margins typically translate into restrained capacity expansion — a supply discipline that benefits pricing for DRAM and NAND globally, indirectly supporting US and Taiwanese chip stocks including Micron and TSMC. Domestically, Korean chip equipment and substrate suppliers such as Wonik IPS and ASEH benefit from any ramp in advanced packaging capacity. Institutional investors exposed to Korean equities through ETFs or direct holdings will see earnings revision cycles lifting index weights if the 2027 forecast proves accurate.

Key forward signals include quarterly HBM shipment volumes and average selling price trends — these determine whether the profit surge materialises ahead of or behind schedule. Investors should also watch Samsung's foundry division: any recovery in logic chip margins alongside memory upside would be a dual catalyst. The macro variable is global AI datacenter capex commitments by Amazon, Microsoft, and Google for 2026-2027; a slowdown in hyperscaler spending would compress HBM demand and delay the earnings acceleration both chipmakers need to meet 2027 targets.
