LEADERSHIP FINANCIALS INDUSTRY INVESTMENT HIGHLIGHTS GROWTH STRATEGIES BUSINESS OFFERING SUMMARY 8 Sales, Marketing & Competition SALES & MARKETING o Currently, our ending products are described as price inelastic. The demand for copper and aluminum materials is stable despite fluctuating market prices. The stability is attributable to the widespread use of these materials in vast industries. The primary constraint on sales is our production capacity. o Our marketing team also participates in some international exhibitions of renewable resources in the United States, Europe and China. The management expects to acquire new customers through these events to mitigate the risk of customer concentration. COMPETITION o The Recycled Metal industry in the Philippines is highly diversified and competitive, with many players in the market. o As demand for recycled metal grows, more small enterprises are expected to enter the industry, and the major companies are expected to expand their influence and increase their market share in the approaching years. *source: the International Energy Agency (IEA) Note: Refer to the offering documents for further risks and disclosures.
