  • Proportion of sales: This represents 9.51% of the company's 2025 consolidated sales.
  • Contract period: From May 26, 2026 to December 31, 2026.
  • Payment terms: 90% after delivery, 10% after SETUP completion.
  • Counterparty: Samsung Electronics (recent sales of 3336.5 trillion KRW), a highly reliable customer, suggesting potential for additional orders.
  • Impact: The contract is expected to be reflected in 2026 revenue, contributing positively to short-term performance. However, given its modest proportion of total sales, the impact on stock price is limited.
  • [AI Comprehensive Analysis]YEST’s equipment supply contract with Samsung Electronics is positive in terms of securing a high-quality customer, but the contract size at 9.5% of sales is not a major inflection point. Future additional orders and 2026 performance outlook are key.
