RF Materials Announces 41.9 Billion Won Rights Offering to Fund AI Data Center Capacity Expansion... Full Participation by Major Shareholder Eases Dilution Concerns


  • RF Materials decided to conduct a rights offering followed by a public offering of 500,000 shares (dilution approx. 5.89%) to raise a total of 419.5 billion won for facility investment (25 billion won) and operating funds (16.95 billion won). The 1st issue price is 83,900 won, with the final price to be set on June 15.
  • The controlling shareholder, RFHIC (41.54% stake), plans to fully subscribe to its allotment (207,708 shares), maintaining its stake at 41.54% post-offering. Participation of other related parties is undecided, creating potential ownership change.
  • Use of proceeds: land balance payment (8.78 billion won), new factory construction (16.22 billion won), and raw material (PGC) purchase for AI data center pump laser packages (8.2 billion won). Land acquisition in July 2026, factory completion targeted for Q4 2027.
  • FY2025 consolidated revenue reached 64.08 billion won (+44% YoY), operating profit 7.37 billion won (turnaround), net income 10.38 billion won. Debt ratio 48.4%, net cash position maintained. Q1 2026 also strong with operating profit of 3.2 billion won.
  • Extreme stock price volatility (low 4,245 won in Dec 2024 to high 116,900 won in Apr 2026). The stock has been designated as a warning stock 3 times and a cautionary stock 13 times in the last 3 years. The listing of new shares (expected July 9) may create short-term supply pressure.
  • High customer concentration: top two customers (A: 49.2%, B: 19.8%) account for 69% of sales. Despite surging raw material prices (gold up 168% in 5 years), the company managed to raise selling prices by ~15% in 2025 to partially offset.
  • The facility investment responds to increased orders for pump laser packages for AI data centers (e.g., 7.29 billion won contract with Lumentum), securing medium-to-long-term growth. However, risks include initial yield stabilization and customer certification delays.
  • [AI Comprehensive Analysis]This rights offering is a preemptive investment for AI data center growth, with full controlling shareholder participation aligning interests. However, high stock volatility, customer and raw material concentration, and new share overhang may negatively impact short-term stock price, warranting cautious investment.
