An examination of short-term operating activity ratios reveals fluctuating performance over the five-year period. Several ratios demonstrate considerable volatility, while others exhibit more consistent, though not necessarily positive, trends. Overall, the period concludes with indications of improved efficiency in certain areas, but also continued challenges in others.

Inventory Management

Inventory turnover decreased significantly from 1.58 in 2021 to 0.89 in 2023, indicating a substantial slowdown in the rate at which inventory was sold. This trend reversed in subsequent years, rising to 1.84 in 2024 and 1.93 in 2025, suggesting improved inventory management. Correspondingly, the average inventory processing period lengthened from 231 days in 2021 to a peak of 411 days in 2023, before decreasing to 189 days in 2025. This mirrors the inventory turnover trend, indicating that inventory is taking less time to be converted into sales in the later years of the period.

Receivables Management

Receivables turnover declined from 4.96 in 2021 to 3.70 in 2023, suggesting a lengthening of the time required to collect receivables. It partially recovered to 4.72 in 2024, but decreased again to 3.67 in 2025. The average receivable collection period increased from 74 days in 2021 to 99 days in both 2023 and 2025, reinforcing the observation of slower collections. This suggests potential issues with credit policies or collection efforts.

Payables Management

Payables turnover exhibited an upward trend, increasing from 4.72 in 2021 to 6.74 in 2024, before decreasing to 5.09 in 2025. This indicates that the company paid its suppliers more frequently in 2024. The average payables payment period decreased from 77 days in 2021 to 54 days in 2024, then increased to 72 days in 2025, aligning with the payables turnover trend. This suggests a fluctuating ability to negotiate favorable payment terms with suppliers.

Overall Operating Efficiency

Working capital turnover demonstrated significant fluctuation. It increased from 3.37 in 2021 to 3.82 in 2022, then decreased sharply to 2.25 in 2023, before a substantial increase to 5.40 in 2024 and a further increase to 9.85 in 2025. This suggests a considerable improvement in the efficiency with which working capital is used to generate sales in the latter part of the period. The operating cycle lengthened from 305 days in 2021 to 510 days in 2023, then decreased to 288 days in 2025, reflecting the combined effects of changes in inventory, receivables, and payables. The cash conversion cycle followed a similar pattern, increasing to 441 days in 2023 and decreasing to 216 days in 2025.

In conclusion, the company experienced a period of operational instability, particularly between 2021 and 2023. However, the latter years of the period (2024 and 2025) show signs of improvement in inventory and working capital management, although receivables collection remains a potential area of concern.

The analysis of inventory turnover reveals fluctuating performance over the five-year period. Initially, a decline in inventory turnover is observed, followed by a subsequent recovery and slight improvement.

Inventory Turnover Trend

The inventory turnover ratio decreased from 1.58 in 2021 to 1.30 in 2022, indicating a slowing in the rate at which inventory was sold and replenished. This downward trend continued into 2023, with the ratio falling to 0.89, suggesting a significant slowdown in inventory activity. However, a substantial increase occurred in 2024, with the ratio rising to 1.84. This improvement persisted into 2025, with a further increase to 1.93, representing the highest ratio observed during the analyzed period.

Cost of Sales Relationship

Cost of sales generally increased over the period, rising from US$6,454 million in 2021 to US$12,858 million in 2024 before decreasing slightly to US$12,037 million in 2025. The initial decline in inventory turnover from 2021 to 2023 did not coincide with a substantial decrease in cost of sales, suggesting potential issues with inventory management or demand forecasting during those years. The subsequent increase in inventory turnover in 2024 and 2025 aligns with the elevated cost of sales, indicating improved efficiency in converting inventory into sales.

Inventory Levels

Inventory levels increased from US$4,086 million in 2021 to US$9,518 million in 2023. This increase likely contributed to the decline in inventory turnover during those years. A significant reduction in inventory occurred in 2024, falling to US$6,998 million, and continued to decrease to US$6,225 million in 2025. This reduction in inventory, coupled with the increasing cost of sales, likely drove the improvement in inventory turnover observed in the latter years of the period.

In summary, the company experienced a period of declining inventory efficiency, followed by a notable recovery. The changes in inventory turnover appear to be correlated with both cost of sales and inventory levels, suggesting that management actions related to inventory control and sales strategies have had a measurable impact.

An examination of the provided financial information reveals trends in product sales, trade receivables, and the receivables turnover ratio over a five-year period. Product sales demonstrate a consistent upward trajectory, while trade receivables and the receivables turnover ratio exhibit more fluctuation.

Product Sales

Product sales increased steadily from US$24,297 million in 2021 to US$35,148 million in 2025. This represents a cumulative growth of approximately 44.7% over the period. The largest year-over-year increase occurred between 2022 and 2023, followed by 2023 and 2024.

Trade Receivables, Net

Trade receivables experienced an initial increase from US$4,895 million in 2021 to US$7,268 million in 2023. However, a decrease was observed in 2024 to US$6,782 million, before rising again to US$9,570 million in 2025. This suggests potential variations in collection efficiency or changes in credit terms extended to customers. The most substantial increase in receivables occurred between 2024 and 2025.

Receivables Turnover

The receivables turnover ratio decreased from 4.96 in 2021 to 4.46 in 2022, indicating a lengthening of the average collection period. A more pronounced decline was noted in 2023, with the ratio falling to 3.70. The ratio saw a partial recovery in 2024, increasing to 4.72, but then decreased again in 2025 to 3.67. This fluctuating trend suggests inconsistency in the speed at which the company collects its receivables. The lower turnover in 2023 and 2025, despite increasing sales, warrants further investigation into potential issues with credit policies or collection processes. The ratio’s movement does not consistently align with the growth in product sales, suggesting that increases in sales are not necessarily translating into faster collection of receivables.

In summary, while product sales demonstrate strong growth, the receivables turnover ratio exhibits volatility. The increasing trade receivables, coupled with a declining receivables turnover in the latter years of the period, suggest a potential need to review and optimize credit and collection policies to ensure efficient working capital management.

The accounts payable activity demonstrates a fluctuating pattern over the five-year period. Cost of sales generally increased, while accounts payable and the resulting payables turnover exhibited more complex behavior.

Cost of Sales

Cost of sales remained relatively stable between 2021 and 2022, experiencing a decrease from US$6,454 million to US$6,406 million. A significant increase is then observed, rising to US$8,451 million in 2023, followed by a substantial jump to US$12,858 million in 2024. A slight decrease to US$12,037 million is noted in 2025, though remaining considerably higher than earlier years.

Accounts Payable

Accounts payable increased from US$1,366 million in 2021 to US$1,572 million in 2022, representing a moderate rise. This upward trend continued, albeit at a slower pace, reaching US$1,590 million in 2023. A more pronounced increase is seen in 2024, with accounts payable reaching US$1,908 million, and further increasing to US$2,367 million in 2025. The growth in accounts payable appears to lag behind the increases in cost of sales, particularly in 2024 and 2025.

Payables Turnover

The payables turnover ratio decreased from 4.72 in 2021 to 4.08 in 2022, indicating a lengthening of the time it takes to pay suppliers. The ratio then increased to 5.32 in 2023, suggesting improved efficiency in paying down accounts. A substantial increase to 6.74 is observed in 2024, the highest value in the period, indicating a significantly faster turnover of payables. The ratio decreased to 5.09 in 2025, remaining elevated but below the 2024 peak. The fluctuations in payables turnover generally correlate with the changes in cost of sales and accounts payable, with the largest increase coinciding with the largest increase in cost of sales.

Overall, the company appears to be managing its payables effectively, with the turnover ratio generally increasing alongside cost of sales. However, the increase in accounts payable in the later years suggests a potential shift in supplier relationships or payment terms, warranting further investigation.

The working capital turnover ratio exhibited considerable fluctuation over the five-year period. Initial values indicated a moderate level of efficiency in utilizing working capital to generate sales, followed by periods of both improvement and decline.

Working Capital Trend

Working capital decreased from US$7,201 million in 2021 to US$6,499 million in 2022. A substantial increase was then observed in 2023, reaching US$11,940 million, before declining significantly to US$5,931 million in 2024 and further to US$3,568 million in 2025. This suggests evolving strategies regarding current asset and current liability management.

Product Sales Trend

Product sales demonstrated a consistent upward trend throughout the period. Sales increased from US$24,297 million in 2021 to US$24,801 million in 2022, then to US$26,910 million in 2023. Further growth was seen in 2024 with sales reaching US$32,026 million, and continued into 2025 with US$35,148 million in sales. This indicates a growing demand for the company’s products.

Working Capital Turnover Ratio Analysis

The working capital turnover ratio began at 3.37 in 2021 and increased to 3.82 in 2022, indicating improved efficiency in converting working capital into sales. However, the ratio decreased substantially to 2.25 in 2023, potentially due to the significant increase in working capital outpacing sales growth. A marked improvement occurred in 2024, with the ratio rising to 5.40, and continued strongly in 2025, reaching 9.85. This suggests a substantial increase in the efficiency of working capital utilization in the latter years of the period, potentially driven by improved inventory management or more efficient accounts receivable collection, alongside continued sales growth.

The divergence between working capital levels and the turnover ratio highlights a complex relationship. While working capital fluctuated, the increasing turnover ratio in the final years suggests a greater ability to generate sales from each dollar invested in working capital, despite the overall decrease in working capital balance.

The average inventory processing period exhibited considerable fluctuation over the five-year period. Initial values indicated a relatively lengthy processing time, which increased substantially before decreasing again. Inventory turnover mirrored this pattern, though with a different scale.

Average Inventory Processing Period

The average inventory processing period began at 231 days in 2021. A significant increase was observed in 2022, rising to 281 days, and continued to climb to a peak of 411 days in 2023. This suggests a substantial slowdown in the rate at which inventory was sold and replenished during this timeframe. A marked improvement occurred in 2024, with the period decreasing to 199 days. This trend continued into 2025, with a further reduction to 189 days. The decline from 2023 to 2025 indicates improved inventory management efficiency or increased demand.

Inventory Turnover

Inventory turnover demonstrated an inverse relationship with the average inventory processing period. The ratio was 1.58 in 2021, decreasing to 1.30 in 2022, and reaching a low of 0.89 in 2023. This decline aligns with the extended processing period, indicating inventory was being held for longer durations. A substantial increase to 1.84 in 2024, followed by a further increase to 1.93 in 2025, suggests a faster rate of inventory sales and replacement, consistent with the decreasing processing period. The 2024 and 2025 values represent a return towards the initial 2021 level.

The combined trends suggest a period of inventory management challenges in 2022 and 2023, followed by successful corrective actions or favorable market conditions in 2024 and 2025. The increasing inventory turnover and decreasing processing period from 2023 to 2025 are positive indicators of operational efficiency.

The average receivable collection period exhibited fluctuations over the five-year period. While the receivables turnover ratio demonstrated some variability, the collection period provides a clearer picture of changes in the efficiency of collecting receivables.

Average Receivable Collection Period

The average receivable collection period increased from 74 days in 2021 to 82 days in 2022, indicating a lengthening in the time required to collect receivables. This trend continued into 2023, with the period reaching 99 days. A subsequent decrease was observed in 2024, falling to 77 days. However, the period returned to 99 days in 2025, mirroring the 2023 value.

The increase in the collection period in 2022 and 2023 suggests a potential slowdown in the company’s ability to convert receivables into cash. This could be attributable to changes in credit policies, customer payment behavior, or collection efforts. The improvement in 2024 may indicate successful implementation of strategies to accelerate collections, but the return to a longer period in 2025 warrants further investigation.

The cyclical nature of the collection period, with increases followed by a decrease and then another increase, suggests the presence of underlying factors that influence the timing of cash receipts. Monitoring these factors and their impact on the collection period is crucial for maintaining optimal working capital management.

Receivables Turnover

The receivables turnover ratio generally moved inversely with the average collection period. It decreased from 4.96 in 2021 to 4.46 in 2022, and further to 3.70 in 2023, aligning with the lengthening collection period. An increase to 4.72 in 2024 coincided with the shorter collection period observed in that year. However, the ratio decreased again to 3.67 in 2025, consistent with the extended collection period.

The fluctuations in the receivables turnover ratio reinforce the observation that the company’s efficiency in collecting receivables varied over the period. A lower turnover ratio indicates that receivables are being collected more slowly, while a higher ratio suggests faster collection.

Overall, the analysis indicates a degree of inconsistency in the company’s receivables management. The return to longer collection periods and lower turnover in the most recent year suggests a need to reassess collection strategies and identify the root causes of these fluctuations.
