Second, there are fundamental flaws in the profit structure. Raw-material costs have long remained above 85% of revenue, reaching 87.5% in the first three quarters of 2025—well above the industry average. This was compounded by a 63.7% surge in selling and marketing expenses in 2024 and a 20.1% increase in administrative expenses; cost growth far outpaced revenue growth, keeping gross margin under sustained pressure.
