存货规模大幅上升

Our inventories increased to RMB123.3 million as of December 31, 2025, primarily due to (i) an increase in finished goods, primarily comprising NBS, ESC and NBC products, driven by customer order demand and production planning; and (ii) an increase in raw materials, driven by higher inventory levels maintained to support production needs associated with business growth.

Our inventories turnover days decreased from 128 days in 2023 to 85 days in 2024 and subsequently decreased to 69 days in 2025, primarily due to more efficient procurement planning, optimized inventory control processes and increased market demand for our products, which accelerated sales and shortened the inventory turnover cycle and generally in line with our business growth.

As of May 31, 2026, RMB85.3 million, or 61.3% of our gross inventories as of March 31, 2026, had been used, consumed or sold.

Our inventories increased by 36.5% from RMB916.8 million as of December 31, 2024 to RMB1,251.3 million as of December 31, 2025, primarily due to (i) an increase in contract fulfillment costs, arising from higher number of outstanding contracts, in line with the expansion of our business and (ii) an increase in raw materials, as a result of our production expansion to meet growing customer demand.

Our inventory turnover days decreased from 90 days in 2023 to 81 days in 2024, and further decreased to 75 days in 2025, primarily because (i) several data intelligence solution projects were finally accepted in 2024 and 2025 and (ii) we continued to improve our inventory management, resulting in higher inventory turnover efficiency.

As of May 31, 2026, RMB564.5 million, or 43.5% of inventories as of March 31, 2026, had been used, consumed or sold subsequent to March 31, 2026.

It further surged by 107.9% to RMB2,158.5 million as of December 31, 2025, primarily attributable to (i) the continued expansion of our sales scale, which necessitated higher inventory levels to support the increased transaction volumes and fulfilment requirements, and (ii) longer customs inspection and clearance cycles for certain imported beef products following the implementation of new inspection and quarantine policies in 2025, which resulted in such products remaining in inventory for a longer period before release.

Our average inventory turnover days increased from 58 days in 2023 to 82 days in 2024, and further to 101 days in 2025.

Based on the foregoing, Frost & Sullivan is of the view that our inventory turnover days recorded during the Track Record Period are consistent with the operational characteristics of our business model.

Our inventories further increased to RMB282.4 million as of December 31, 2025 and to RMB303.4 million as of March 31, 2026.

While we proactively raised our inventory level to meet the rising market demand during the Track Record Period, we provided for impairment when inventory reached predetermined age thresholds and when net realizable value, determined by reference to order prices or prevailing market prices, fell below cost, resulting in increased write-down of inventories.
