YTD as of 2026-07-10 · source: Yahoo Finance
The thesis is the interplay of two engines — the Middle East hydrocarbon order cycle and Samsung group work. In FY2025, 53.5% of revenue came from just two customers, Aramco (31.4%) and Samsung Electronics (22.0%), exposing it simultaneously to oil-price/Middle East capex and Samsung's fab investment — two different cycles. Record 2024 new orders of KRW 14.4tn and megaprojects (Fadhili gas, Ta'ziz methanol) pre-booked 2025-2027 revenue, while New Energy (LNG, SAF, water) broadens the hydrocarbon concentration. With 74% of cost in equipment and subcontracting (KRW 6.06tn), supplier sourcing and FX decide margins, and dependence on two large customers is both the stability and the biggest risk of its growth.
