The operational activity ratios indicate a strategic shift toward increased inventory efficiency and a significant extension of supplier payment terms over the analyzed period.

Inventory Management Efficiency

Inventory turnover exhibits a general upward trajectory, rising from 7.90 in March 2022 to a peak of 10.04 in March 2026, before settling at 9.10 in September 2026. This improvement in turnover is mirrored by the average inventory processing period, which decreased from 46 days in early 2022 to a low of 36 days in the first half of 2026. These trends suggest an enhanced ability to move stock more rapidly, reducing the duration that capital remains tied up in inventory.

Payables and Supplier Credit Trends

A sustained downward trend is observed in the payables turnover ratio, which declined from 4.03 in March 2022 to 2.44 by September 2026. Parallel to this, the average payables payment period extended significantly, increasing from 91 days to 149 days. This shift indicates a strategic extension of the payment cycle, allowing the organization to leverage supplier credit more aggressively to fund short-term operations.

Working Capital Utilization

Working capital turnover demonstrates extreme volatility starting from December 2023. The ratio reached a substantial peak of 413.97 in September 2025, followed by a sharp contraction to 19.34 in March 2026. This high level of variance suggests significant fluctuations in the proportion of net working capital relative to sales, indicating potential shifts in liquidity management or substantial changes in current asset and liability balances.

The analyzed period demonstrates a sustained increase in operational volume coupled with a general improvement in inventory management efficiency. Cost of sales exhibits a consistent long-term growth trajectory, characterized by recurring seasonal peaks every fourth quarter.

Cost of Sales Trends

An upward trajectory is observed in the cost of sales, rising from 66,499 million USD in March 2022 to 94,573 million USD by September 2026. The data reveals a strong seasonal correlation, with the highest expenditures consistently occurring in the December quarters, reaching a peak of 109,959 million USD in December 2025.

Inventory Level Dynamics

Inventory balances have remained relatively stable despite the growth in sales volume, fluctuating between a minimum of 31,147 million USD in March 2024 and a maximum of 42,632 million USD in September 2026. This indicates that inventory growth has not scaled linearly with sales, suggesting an optimization of stock levels.

Inventory Turnover Efficiency

The inventory turnover ratio shows a positive trend in operational efficiency over the timeframe. The ratio improved from 7.90 in March 2022 to a peak of 10.04 in March 2026. Although a slight contraction in efficiency occurred during 2025, with the ratio dipping to 8.27 in June, the overall trend reflects an increased velocity in moving inventory through the supply chain.

The analysis of the payables turnover reveals a sustained long-term decline in the frequency with which supplier obligations are settled. While the ratio exhibits recurring seasonal volatility, the overall trajectory indicates a shift toward a slower payment cycle, moving from a range of 3.63 to 4.34 in 2022-2023 to a low of 2.44 by the third quarter of 2026.

Seasonal Turnover Patterns

A consistent cyclical contraction in the payables turnover ratio is observed during the fourth quarter of each year. Specifically, the ratio reached annual lows in December 2022 (3.63), December 2023 (3.59), and December 2025 (2.92). These dips coincide with the peak quarterly cost of sales, indicating that the volume of credit purchases increases significantly during the year-end period, temporarily slowing the turnover rate.

Divergence Between Liabilities and Costs

There is a marked divergence between the growth rate of accounts payable and the growth rate of the cost of sales. From March 31, 2022, to September 30, 2026, cost of sales increased from 66,499 million to 94,573 million. In contrast, accounts payable grew more aggressively, rising from 68,547 million to 158,715 million. This disproportionate expansion of liabilities relative to operating costs is the primary driver behind the declining turnover ratio.

Working Capital Management Trend

The trend from 2024 onward shows a steady erosion of the turnover ratio, falling from 4.24 in March 2024 to 2.44 in September 2026. This indicates an operational shift toward extending payment terms to suppliers. By retaining cash for longer periods, the company has effectively increased its liquidity through an expansion of its accounts payable, suggesting an increased leverage over the supply chain or a strategic decision to optimize working capital.

The financial data indicates a significant transition in the management of short-term operating assets and liabilities, characterized by a shift from a negative working capital model to a period of high volatility and positive working capital. While net sales exhibit a consistent upward trajectory with pronounced seasonal peaks, the working capital turnover ratio demonstrates extreme fluctuations, reflecting instability in the relationship between sales volume and net current assets.

Net Sales Performance

A steady growth trend is observed in net sales, increasing from 116,444 million in March 2022 to 201,944 million by September 2026. A recurring seasonal pattern is evident, with the highest sales volumes consistently recorded in the December quarters of each fiscal year, peaking at 213,386 million in December 2025.

Working Capital Dynamics

Working capital remained negative from March 2022 through September 2023, reaching a trough of -11,349 million in March 2023. A fundamental shift occurred in December 2023, when working capital turned positive at 7,434 million. This positive trend continued with significant volatility, culminating in a sharp peak of 38,399 million in March 2026, before returning to a negative position of -2,882 million by September 2026.

Working Capital Turnover Volatility

The working capital turnover ratio exhibits extreme instability. From December 2023 to June 2024, the ratio declined from 77.32 to 39.93, indicating a period where working capital grew faster than net sales. A dramatic spike to 413.97 was recorded in September 2025, resulting from a sharp contraction in working capital to 1,670 million against high sales volume. Conversely, the ratio plummeted to 19.34 in March 2026, coinciding with the surge in working capital to 38,399 million. The absence of a ratio in September 2026 is consistent with the return to negative working capital, rendering the traditional turnover calculation non-applicable.

An analysis of the short-term operating activity ratios reveals a general improvement in inventory management efficiency between March 2022 and September 2026. The inverse relationship between inventory turnover and the average inventory processing period indicates a strategic trend toward accelerating the conversion of inventory into sales.

Inventory Turnover Trend

A sustained upward trajectory in the inventory turnover ratio is observed, moving from 7.90 in March 2022 to a peak of 10.04 in March 2026. While the ratio exhibits quarterly volatility, a clear progression is evident from the 7.30 to 8.40 range in 2022 to a higher baseline of approximately 9.10 to 10.00 in 2026. This indicates a more frequent cycling of stock and enhanced operational throughput over the analyzed period.

Average Inventory Processing Period Analysis

The average inventory processing period demonstrates a corresponding downward trend, reflecting a reduction in the number of days inventory remains in stock. Starting at 46 days in March 2022, the period reached its lowest points of 36 days in March and June 2026. Although periodic increases occurred—such as the rise to 44 days in mid-2025—the overall trend confirms a compression of the inventory cycle, which suggests improved liquidity and reduced holding costs.

Seasonal Volatility and Efficiency Correlation

Cyclical patterns are observable in the quarterly data, particularly around the year-end periods. For instance, inventory turnover consistently peaks or strengthens toward December 31 (reaching 9.15 in 2023 and 9.54 in 2024), which correlates with a reduction in the inventory processing period to 40 and 38 days, respectively. The most significant efficiency gains are noted in the first half of 2026, where the processing period hit a minimum of 36 days, coinciding with the highest recorded turnover ratios.

Analysis of the operating activity ratios reveals a progressive extension in the duration of supplier payment cycles and a corresponding decrease in turnover frequency over the observed period from March 2022 to September 2026.

Payables Turnover Trends

The payables turnover ratio remained relatively stable between 3.59 and 4.34 through the end of 2023. Beginning in March 2024, a consistent downward trajectory is observed, with the ratio declining from 4.24 to a period low of 2.44 by September 2026. This contraction indicates a reduction in the frequency with which the entity settles its accounts payable obligations.

Average Payables Payment Period Analysis

The average payables payment period exhibited moderate volatility, ranging between 84 and 102 days from March 2022 to December 2023. Following this period, a pronounced upward trend emerged. The payment window expanded from 102 days in December 2023 to 149 days by September 2026. This represents a significant increase in the average time elapsed before suppliers are paid.

The inverse correlation between payables turnover and the payment period is maintained throughout the dataset. The sustained expansion of the payment period suggests an increasing reliance on supplier credit as a source of short-term financing. By extending the time to discharge payables, the organization effectively enhances its liquidity position and optimizes working capital management.
