Higher sales volumes did not prevent a sharp margin decline
The FY2023 main-business table reports glass-fiber and related-product revenue of CNY 14,422,519,043.04 and cost of CNY 10,446,817,040.40. Revenue fell 14.49% while cost rose 5.94%; the reported gross margin was 27.57%. Management links lower revenue and margins to a large fall in glass-fiber selling prices, despite increased domestic and overseas sales volumes. The table gives a margin decline of 13.96 percentage points, whereas the adjacent narrative says 13.97; the difference is retained as a source inconsistency, with no invented correction. These are product-category main-business results, not the listed group’s total consolidated revenue or the profit of a particular furnace. The separate other-product row has CNY 136,931,126.74 revenue and a 2.24% margin; this FY2023 passage does not identify it as the wind-generation business described in the later FY2024 filing.
