REASONS FOR THE ESTIMATED CHANGES IN RESULTS In the first half of 2024 affected by various factors such as external demand and industry competition the hazardous waste market continued to decline. During the Reporting Period the average collection and transportation prices for various types of waste still showed a year-on- year decline and the rising upstream metal prices have not yet been reflected in downstream products These exerted pressure on the profitability of the Company's three main businesses: harmless treatment recycling and precious metal recycling and hence causing the gross profit margin to remain at a lower level. Although the Company continued to record a loss in the second quarter the loss has narrowed and was mainly attributable to amortization and depreciation. The Company’s core operations remained stable.In response to the difficult industry and operational challenges the new management team of the Company on the basis of diligent careful analysis of the Company’s operations sought breakthroughs and revolutions with extreme thoughts and strived for changes. The "Three Extremes and Four Strengths" operational philosophy and measures were swiftly formulated focusing on "strengthening assessment strengthening restrictions strengthening incentives and strengthening tolerance" to effectively implement the three key initiatives: "extreme efficiency enhancement extreme cost reduction and extremely efficient transformation." With the continuous strengthening of macro-control measures in Mainland China and the introduction of policies supporting the circular economy the Company will seek new transformation opportunities on the basis of solid core operations so as to build momentum for the next phase of high-quality development.IV.
