The operational efficiency metrics indicate a strategic shift in working capital management, characterized by a lengthening operating cycle and a sustained negative cash conversion cycle. There is a notable trend toward slower asset turnover offset by extended supplier payment terms.

Inventory Dynamics

Inventory turnover exhibits significant volatility, reaching a peak of 45.20 in 2022 before declining to 16.86 by 2026. This decline is reflected in the average inventory processing period, which remained relatively stable between 8 and 13 days from 2021 to 2025 but experienced a sharp increase to 22 days in 2026, indicating a slowdown in the rate at which inventory is converted into sales.

Receivables Performance

A gradual deterioration in receivables turnover is observed, decreasing from 13.92 in 2021 to 10.93 in 2026. Consequently, the average receivable collection period lengthened from 26 days to 33 days over the same period, suggesting a trend toward slower collections from customers.

Payables and Supplier Financing

Payables turnover shows a consistent downward trend, moving from 3.89 in 2021 to 2.98 in 2026. This corresponds with an increase in the average payables payment period, which rose from 94 days to 122 days. This pattern indicates an increased reliance on supplier financing to fund operations.

Operating and Cash Conversion Cycles

The operating cycle has expanded from 37 days in 2021 to 55 days in 2026, driven by both slower inventory turnover and slower receivable collections. Despite this extension, the cash conversion cycle remains negative throughout the period, ranging between -57 and -76 days. This indicates that the company continues to generate cash from sales before paying its suppliers, effectively using trade payables as a source of interest-free financing.

Working Capital Efficiency

Working capital turnover increased substantially from 39.10 in 2021 to 121.47 in 2026. This suggests a significant increase in the efficiency of using working capital to generate revenue, likely influenced by the aggressive management of the cash conversion cycle.

The analysis of inventory management from 2021 to 2026 reveals a period of relative stability followed by a significant shift in operational efficiency during the final fiscal year. While cost of sales remained within a consistent range for the first five years, a sharp increase in inventory levels in 2026 led to a substantial contraction in the inventory turnover ratio.

Cost of Sales Trends

Expenditures related to the cost of sales exhibited moderate fluctuations between 2021 and 2025, moving from 212,981 million US$ to 220,960 million US$. However, a notable increase occurred in 2026, where costs rose to 245,232 million US$, representing the highest value in the observed period.

Inventory Level Fluctuations

Inventory balances remained relatively lean between 2021 and 2025, fluctuating between a low of 4,946 million US$ in 2022 and a high of 7,286 million US$ in 2024. This stability ended abruptly in 2026, as inventories surged to 14,541 million US$, more than doubling the previous year's balance.

Inventory Turnover Efficiency

The inventory turnover ratio peaked in 2022 at 45.20, indicating highly efficient inventory movement. A period of volatility followed, with the ratio dipping to 28.87 in 2024 before recovering to 38.64 in 2025. A sharp decline is observed in 2026, with the ratio falling to 16.86, the lowest point in the analyzed timeframe.

Operational Correlation

The correlation between the surge in inventory levels and the decline in the turnover ratio in 2026 suggests a significant reduction in the speed at which inventory is converted into sales. Despite the increase in the cost of sales, the disproportionate growth in inventory holdings resulted in a marked decrease in overall operating efficiency regarding stock management.

An analysis of the financial data from September 2021 through September 2026 reveals a general expansion in top-line revenue accompanied by a gradual decline in the efficiency of receivables collection. While net sales have exhibited a strong overall growth trajectory, the acceleration in the growth of accounts receivable has led to a downward trend in the receivables turnover ratio for the majority of the period.

Net Sales Trends

Net sales demonstrated a general upward trend, increasing from 365,817 million US$ in 2021 to 478,834 million US$ by 2026. Although a marginal contraction occurred in 2023, the subsequent years showed accelerated growth, particularly between 2025 and 2026, where sales increased by approximately 14.5%.

Accounts Receivable Growth

Accounts receivable, net, grew consistently every year throughout the analyzed period. The balance rose from 26,278 million US$ in 2021 to 43,817 million US$ in 2026. The pace of this increase accelerated notably after 2023, with the largest absolute increase occurring between 2024 and 2025.

Receivables Turnover Performance

The receivables turnover ratio remained stable between 2021 and 2022, peaking at 13.99. However, a consistent decline was observed from 2022 through 2025, reaching a period low of 10.46. This indicates that the company took longer to collect its outstanding receivables relative to its sales volume. A slight recovery to 10.93 was recorded in 2026, suggesting a potential stabilization in collection efficiency.

Correlation Analysis

The divergence between the growth rate of net sales and the growth rate of accounts receivable explains the compression of the turnover ratio. The increase in receivables outpaced the increase in sales from 2022 to 2025, resulting in lower turnover. The slight uptick in the ratio in 2026 coincides with the most significant surge in net sales, indicating that revenue growth finally began to outpace the accumulation of receivables.

An analysis of the operating activity ratios reveals a consistent decline in the payables turnover ratio over the observed six-year period. The ratio decreased from 3.89 in September 2021 to 2.98 by September 2026, indicating a slowing frequency of supplier payments.

Payables Turnover Trend

The downward trajectory of the turnover ratio suggests a systemic extension of the payment cycle. While a marginal increase to 3.16 was observed in 2025, the overarching trend reflects a reduction in the number of times accounts payable are cleared annually, moving from nearly four times per year to approximately three.

Accounts Payable and Cost of Sales Dynamics

Accounts payable grew from 54,763 million USD in 2021 to 82,252 million USD in 2026. Although the cost of sales also exhibited an upward trend—particularly in the final two years, peaking at 245,232 million USD—the growth in payable balances has generally outpaced the growth in cost of sales, which directly contributes to the decline in the turnover ratio.

Operational and Liquidity Implications

The decrease in the payables turnover ratio implies an increase in the average number of days required to pay suppliers. This suggests an enhancement in the company's ability to utilize supplier credit as a source of interest-free financing, thereby optimizing short-term cash flow and demonstrating significant leverage over the supply chain.

Analysis of short-term activity indicates a general expansion in revenue coupled with significant volatility in working capital management. Net sales exhibited a consistent upward trajectory over the six-year period, increasing from 365,817 million in 2021 to 478,834 million by 2026, with only a minor contraction observed in 2023.

Working Capital Dynamics

Working capital demonstrated substantial fluctuation, moving from a positive position of 9,355 million in 2021 into negative territory for four consecutive years. The most pronounced deficit occurred in 2024, reaching -23,405 million. A reversal of this trend is evident by 2026, when working capital returned to a positive balance of 3,942 million.

Working Capital Turnover Performance

A marked increase in the working capital turnover ratio is observed between the start and end of the analyzed period. The ratio rose from 39.10 in 2021 to 121.47 in 2026, signaling a significantly higher efficiency in utilizing net current assets to generate revenue. The absence of calculations for the intervening years aligns with the periods of negative working capital, where the ratio typically lacks standard interpretative value.

Correlation between Sales and Liquidity

The convergence of record-high net sales in 2026 and the return to a positive working capital position suggests a strategic realignment of current assets and liabilities to support an expanded scale of operations. The substantial rise in the turnover ratio by 2026 indicates that the company is generating significantly more sales relative to its net investment in operating liquidity than it did in 2021.

The analysis of inventory activity ratios reveals significant fluctuations in operational efficiency over the six-year period. While a lean inventory model was maintained for the majority of the timeframe, a substantial shift in performance occurred in the final year of the observation period.

Inventory Turnover Trends

The turnover ratio exhibited high volatility, peaking in 2022 at 45.20, which indicates a period of maximum efficiency in stock movement. A downward trend followed through 2024, with the ratio descending to 28.87. A temporary recovery was observed in 2025 as the ratio rose to 38.64; however, a sharp contraction occurred in 2026, where the ratio fell to 16.86, marking the lowest level of inventory turnover in the reported period.

Average Inventory Processing Period

The processing period remained relatively stable between 2021 and 2025, fluctuating within a narrow range of 8 to 13 days. The most efficient processing time of 8 days was recorded in 2022, corresponding with the peak turnover ratio. A significant deviation is observed in 2026, where the processing period extended to 22 days. This represents a substantial increase in the time required to convert inventory into sales, suggesting a potential accumulation of stock or a decrease in demand velocity.

Correlation and Operational Insight

An inverse correlation is maintained between the turnover ratio and the processing period throughout the data set. The transition from 2025 to 2026 is particularly notable, as the simultaneous drop in turnover and the spike in processing days indicate a marked decline in short-term operating efficiency compared to the historical average of the preceding five years.

The analysis of operating activity ratios indicates a general decline in the efficiency of receivable management from 2021 through 2025, followed by a slight correction in 2026. There is a consistent inverse correlation between the turnover ratio and the collection period throughout the observed timeframe.

Receivables Turnover

A steady downward trend is observed from 2021 to 2025, with the ratio decreasing from 13.92 to a low of 10.46. This contraction suggests a reduction in the frequency with which average receivables are collected during the annual cycle. A marginal recovery occurred in 2026, with the ratio rising to 10.93, indicating a slight improvement in the velocity of credit recovery.

Average Receivable Collection Period

The period required to collect receivables remained stable at 26 days between 2021 and 2022 but experienced a consistent increase thereafter, reaching a peak of 35 days in 2025. This extension of the collection cycle reflects a slower conversion of accounts receivable into cash. In 2026, the collection period decreased to 33 days, signaling a modest enhancement in short-term liquidity management.

The analysis of short-term operating activity reveals a general expansion of the operating cycle over the period from 2021 to 2026. The time required to convert inventory and receivables into cash has increased from 37 days to 55 days, indicating a decrease in overall operating efficiency over the six-year trajectory.

Average Inventory Processing Period

Inventory turnover remained relatively stable and efficient between 2021 and 2025, fluctuating within a tight range of 8 to 13 days. However, a significant inflection point occurred in 2026, where the processing period increased sharply to 22 days. This represents the highest value in the observed period and suggests a notable slowdown in the rate at which inventory is sold.

Average Receivable Collection Period

A gradual upward trend is observed in the collection of receivables, which rose from 26 days in 2021 and 2022 to a peak of 35 days in 2025. A slight contraction to 33 days occurred in 2026. This steady increase suggests a lengthening of credit terms or a deceleration in the efficiency of payment collections from customers over the majority of the period.

Operating Cycle

The total operating cycle experienced a net increase of 18 days over the analyzed timeframe. While the cycle reached its lowest point of 34 days in 2022, it climbed steadily to 44 days by 2025. The most substantial jump occurred between 2025 and 2026, rising from 44 to 55 days. This final increase is primarily attributable to the spike in the inventory processing period rather than changes in receivable collection.

An analysis of the operating activity ratios reveals a consistent shift in the management of accounts payable over the observed period. There is a clear inverse relationship between the payables turnover ratio and the average payment period, indicating a strategic extension of the timeframe utilized to settle obligations with suppliers.

Payables Turnover Ratio

A general downward trajectory is observed in the payables turnover ratio, which declined from 3.89 in September 2021 to 2.98 by September 2026. Despite a marginal increase to 3.16 in 2025, the overall trend indicates that the company is cycling through its accounts payable less frequently relative to its cost of goods sold or total purchases.

Average Payables Payment Period

The average time required to pay suppliers has increased steadily, rising from 94 days in September 2021 to 122 days in September 2026. The period expanded notably to 120 days by September 2024, experienced a slight contraction to 115 days in 2025, and ultimately reached its peak in the final reporting period.

Operational Implications

The extension of the payment period from approximately three months to over four months suggests a strategic optimization of the cash conversion cycle. By delaying payments to vendors, the company increases its available liquidity and effectively utilizes accounts payable as a source of interest-free financing to support short-term operations.

The analysis of the short-term operating activity ratios reveals a consistently negative cash conversion cycle, indicating a highly efficient working capital management strategy where cash is generated from sales before payments to suppliers are required.

Average Inventory Processing Period

Inventory turnover remains generally rapid, fluctuating between 8 and 13 days for the majority of the period. However, a significant increase is observed in the final year, where the period rises to 22 days, suggesting a potential slowdown in inventory turnover or a strategic increase in stock levels.

Average Receivable Collection Period

A gradual upward trend is evident in the collection of receivables, increasing from 26 days in 2021 to a peak of 35 days in 2025, before settling at 33 days in 2026. This suggests a slight expansion in the time required to convert credit sales into cash.

Average Payables Payment Period

The payment period for accounts payable shows a consistent and substantial increase, rising from 94 days in 2021 to 122 days by 2026. This expansion indicates an increasing ability to defer payments to suppliers, which serves as a primary driver for the negative cash conversion cycle.

Cash Conversion Cycle

The overall cycle remains negative throughout the analyzed timeframe, ranging from -57 to -76 days. The most efficient liquidity position was reached in 2024 at -76 days. While there is a slight moderation toward -67 days by 2026, the company continues to operate with a negative working capital model, effectively using supplier financing to fund operations.

The synergy between a very short inventory processing period and an extended payables payment period outweighs the gradual increase in receivable collection times. Consequently, the company maintains a strong liquidity position characterized by an ability to accelerate cash inflows relative to outflows.
