Financial and corporate events influencing revenue and shareholder value

• Strategic partnerships: long-term supply agreements with large global brands underpin multi-year order backlogs and reduce sales volatility.
• Thailand expansion: new facility investment increases annual production capacity and export potential; expected to lift international revenue share and improve per-unit margins as fixed costs are spread.
• Corporate governance events: cancellation of certain stock options in June 2025 and termination of a shareholding reduction plan in July 2025 are notable. These actions can affect:
  • EPS and dilution dynamics (option cancellations reduce potential future dilution);
  • Investor sentiment and cost of capital (termination of share sales may reassure long-term holders or reduce liquidity depending on context);
  • Short-term stock volatility, which can indirectly impact supplier/customer negotiations and financing terms.
• Working capital & capex: PCB manufacturers typically require significant capex to add capacity and maintain technology parity; higher capex funded by operating cash flow or debt affects free-cash-flow profile and net margins.

Key operational metrics that determine profitability

• Capacity utilization - moves gross margin leverage.
• Average selling price (ASP) by PCB type - HDI and automotive boards raise blended ASP.
• Yield and quality metrics - return rates and rework costs materially affect margins.
• Customer mix - percentage of revenue from strategic OEM partners versus spot buyers.
