Inventory Turnover

The inventory turnover ratio exhibits notable fluctuations throughout the periods observed. Initially, it rises from 36.21 to a peak of 45.20 before declining sharply to levels below 30 in several quarters, such as 29.24 and 28.87. Subsequently, it demonstrates a gradual recovery toward the end of the timeline, reaching 38.64. These variations indicate periods of both increased efficiency in managing inventory and phases where turnover slowed, potentially reflecting changes in sales volume or inventory management strategies.

Receivables Turnover

This ratio shows considerable volatility, with values ranging from a low of 10.46 to a high of 21.47. Early in the dataset, receivables turnover increases significantly, reaching nearly 20, then alternates between declines and recoveries. Toward the final periods, there appears to be a declining trend, signaling a possible extension in the collection period or more lenient credit policies.

Payables Turnover

The payables turnover ratio similarly fluctuates, with peaks around 5.10 and troughs close to 2.82 and 2.90. The pattern indicates variability in the company's pace of settling obligations to suppliers, which may be influenced by cash flow management or supplier terms adjustments.

Working Capital Turnover

Available data shows marked spikes, with values such as 52.06 and an exceptionally high 83.07, alongside a value of 39.69. These peaks suggest intervals of highly efficient use of working capital to generate sales. However, the incompleteness of this data limits comprehensive trend interpretation in this area.

Average Inventory Processing Period

This metric remains fairly stable, oscillating mostly between 8 and 13 days, with occasional slight increases such as 13 days around mid-2024. Stability in this period suggests consistent inventory handling practices with minor seasonal or operational variations.

Average Receivable Collection Period

The receivable collection period displays a varied pattern, decreasing sharply early on from 34 to 18 days, followed by recurring increases and decreases, eventually returning to higher values around 35 days in later periods. This inconsistency denotes changing effectiveness in receivables management and possibly varying customer payment behaviors.

Operating Cycle

The operating cycle closely mirrors the behaviors of inventory and receivables periods, ranging from a low of 27 days to a high of 44 days. Periods of shorter cycles indicate improved cash flow efficiency, while longer cycles suggest slower conversion of inventory and receivables into cash.

Average Payables Payment Period

The payables payment period varies substantially, with extreme values such as 129 and 126 days and lows around 72 days. This wide range reflects significant shifts in payment strategies or supplier negotiation outcomes, possibly used to manage liquidity.

Cash Conversion Cycle

The cash conversion cycle remains negative throughout the periods, indicating that payables are paid after inventory and receivables turnover, enhancing cash flow. However, its magnitude fluctuates between -85 and -43 days. Larger negative values correspond to more favorable conditions for working capital management, whereas lesser negatives might signal tighter liquidity management phases.

Summary

Overall, the financial ratios illustrate a dynamic environment with fluctuating efficiencies in working capital components. Inventory management shows resilience with moderate variation, while receivables turnover and collection periods highlight variability in credit management. Payables management appears strategic, with extended payment periods contributing to consistently negative cash conversion cycles, which favor liquidity position. The data suggests ongoing adjustments in operational and financial policies, likely in response to market conditions and company priorities.

The analysis of the quarterly financial data reveals several notable trends related to the cost of sales, inventories, and inventory turnover ratios over the examined periods.

Cost of Sales

The cost of sales exhibited a fluctuating pattern throughout the periods. Initially, there was a notable decrease from $67,111 million to $46,179 million between December 2020 and June 2021. This was followed by an increase to $69,702 million by December 2021. Subsequently, the cost of sales showed a cyclical trend with alternating decreases and increases around the $50,000 to $66,000 million range up to September 2025.

This variability suggests seasonal or operational factors influencing production costs or sales volume, with peaks typically occurring near the year-end quarters.

Inventories

Inventory levels displayed moderate fluctuations, generally ranging between approximately $4,900 million and $7,482 million. Trends indicate slight inventory build-ups in the year-end quarters, such as December 2022 ($6,820 million) and March 2023 ($7,482 million), followed by partial drawdowns in subsequent quarters.

These inventory movements may reflect inventory management practices responding to anticipated sales demand or supply chain considerations.

Inventory Turnover Ratio

The inventory turnover ratio, measuring how often inventory is sold and replaced over a period, varied from a high of 45.2 to a low near 28.87. A declining trend is observable during some stretches, for example, from 40.43 in June 2022 to 28.87 in September 2024. Conversely, periods such as late 2024 to 2025 show an improving turnover ratio, reaching 38.64 by September 2025.

This ratio indicates fluctuating efficiency in inventory utilization, with higher turnover suggesting better sales relative to inventory levels, while lower ratios imply slower movement. The variation may highlight dynamic adjustments in sales cycles or supply chain responsiveness.

Overall, the data reflect a dynamic operational environment characterized by periodic shifts in cost structure and inventory management efficiency. Seasonal patterns appear to influence fiscal quarters differently, impacting both cost of sales and inventory levels, while inventory turnover ratios suggest varying degrees of inventory management effectiveness over time.

Net Sales

Net sales exhibit a cyclical pattern with significant fluctuations over the observed quarters. Periods ending in December consistently show peak sales values, reaching over 120 billion US dollars in some years, which reflects strong seasonal performance likely aligned with holiday periods. Conversely, sales tend to decline in the first and second quarters, with values frequently dropping below 90 billion US dollars. Throughout the timeline, there is no clear linear growth or decline, but sales display a repeated seasonal recovery each fourth quarter, suggesting stable demand patterns with periodic dips after peak seasons.

Accounts Receivable, Net

The accounts receivable balance generally follows a similar seasonal trend as net sales, with higher amounts recorded in the fourth quarter of each year. This pattern indicates increased credit extended to customers during high sales periods. However, the receivables exhibit somewhat higher volatility compared to net sales, with some quarters showing sharper increases or decreases without a consistent growth trend. The peak values often coincide with peak net sales but can vary in magnitude, reflecting changes in credit policy, collection efficiency, or customer payment behavior over time.

Receivables Turnover Ratio

The receivables turnover ratio demonstrates notable fluctuations across the quarters, generally moving inversely with accounts receivable balances. Higher turnover values are observed in quarters when accounts receivable are lower, indicating more rapid collections during these periods. Conversely, turnover tends to decline in quarters where accounts receivable spike, implying slower collections. The ratio values range broadly, peaking above 20 in some quarters and dropping near 10 in others, which points to varying efficiency in receivables management or shifts in customer payment terms. The cyclical pattern aligns with seasonal sales trends, as turnover tends to decrease following periods of peak credit sales.

Overall Insights

The financial data indicates a strong seasonal influence on sales and related receivables. Both net sales and accounts receivable peak in the final quarter of each year, reflecting cyclical business activity. The accounts receivable and receivables turnover ratio exhibit inverse relationships, consistent with expected changes in collection efficiency relative to sales volume. No sustained long-term growth or decline trend is evident; instead, performance appears stable with recurring quarterly patterns. The variation in receivables turnover suggests management attention is needed to maintain or improve collection efficiency following high sales periods to optimize working capital utilization.

The analysis of the quarterly financial data reveals several notable trends and fluctuations across key metrics related to cost of sales, accounts payable, and payables turnover ratio over the observed periods.

Cost of Sales

The cost of sales exhibits a cyclical pattern with peaks and troughs corresponding roughly to yearly seasonal trends. Generally, the cost of sales rises towards the end of each calendar year and dips in the subsequent quarters, indicating potential seasonality in production or sales volume. For example, the highest values typically occur in the December quarters, such as US$ 69,702 million in Dec 2021 and US$ 66,025 million in Dec 2024, while lower values are more common in the mid-year quarters like June and March. There are occasional anomalies such as a drop from 69,702 million in Dec 2021 to 54,719 million in Mar 2022, which may reflect changes in inventory management, supply chain factors, or cost-saving initiatives.

Accounts Payable

Accounts payable figures also show a seasonal pattern, with peaks generally aligning with the December quarter and troughs in the early quarters of the year. The highest accounts payable balance was 74,362 million in Dec 2021, followed by a decline in early 2022, then fluctuating moderately in subsequent quarters. The synchronization between high payables and increased cost of sales around year-end suggests increased purchasing activity or deferred payments to suppliers at those times. There are also notable quarterly variations, such as a rise to 69,860 million in Sep 2025 following relatively lower values in previous quarters, which could indicate growing reliance on credit or extended payment terms.

Payables Turnover Ratio

The payables turnover ratio, indicating the frequency of payables settlement, also reflects a fluctuating yet cyclical trend. Higher turnover ratios typically occur in the first two quarters of each year, suggesting faster payment to suppliers during these periods. For example, peaks such as 5.1 in Apr 2023 and 5.07 in Jun 2021 demonstrate accelerated settlements. Conversely, lower turnover ratios occur towards the year-end quarters, such as 2.9 in Dec 2021 and 3.16 in Sep 2025, implying slower payments or longer credit periods. The ratio's oscillation suggests a strategic management of payables, possibly balancing cash flow preservation with supplier relationships seasonally.

Overall Insights

The interplay among cost of sales, accounts payable, and payables turnover ratios points to a strategic approach in managing supplier payments and inventory costs. The recurring seasonal peaks suggest a pattern consistent with business cycles, likely influenced by product launch schedules, holiday seasons, or fiscal year-end considerations. The fluctuations in payables turnover ratio further highlight adaptive payment strategies, possibly designed to optimize working capital. While peaks in accounts payable align with increased cost of sales periods, the variations in turnover ratios indicate a dynamic credit management approach responsive to cash flow needs.

Working Capital

The working capital figures show significant fluctuations over the observed periods. Initially, there is a decline from 21,599 million USD in late December 2020 to 5,580 million USD by December 2021. Subsequently, the working capital turns negative starting in March 2022, reaching a low point around -23,405 million USD by September 2024. Although there are some intermittent moderate recoveries, the overall trend suggests increasing liquidity pressures or a shift toward higher current liabilities relative to current assets in later periods.

Net Sales

Net sales display a cyclical pattern with peaks generally observed near the end of each calendar year, consistent with seasonal trends. For instance, sales increase from 111,439 million USD in December 2020 to a peak of 123,945 million USD in December 2021, followed by a decrease in the subsequent quarters. This seasonal pattern repeats in the following years, with December quarters consistently producing higher net sales figures, such as 117,154 million USD in December 2022 and 124,300 million USD in December 2024. Overall, net sales maintain a relatively stable range from approximately 80,000 million USD to over 120,000 million USD per quarter, indicating sustained revenue performance with seasonal variability.

Working Capital Turnover

Working capital turnover ratios are provided for selected periods and show high values, suggesting efficient use of working capital to generate sales at these points. For example, a ratio of 67.8 in December 2021 indicates very high turnover, which could relate to lower working capital levels or strong sales. However, data for this ratio is missing in several periods, limiting comprehensive analysis. The available ratios, such as 39.69 and 83.07 in later periods, continue to reflect high turnover, which aligns with the observed low or negative working capital figures, suggesting a potentially aggressive working capital management strategy or short-term financial structuring.

Summary

The overall financial patterns reveal stable yet seasonally variable revenue, with peaks during year-end quarters. Conversely, working capital transitions from a positive balance to prolonged negative values over time, which may indicate increased operational leverage, shifts in asset-liability management, or changes in short-term financing strategies. Despite this, high working capital turnover ratios where available suggest efficient revenue generation relative to the capital employed, albeit with associated liquidity risks. Continuous monitoring of liquidity metrics is advisable to assess any impact on operational stability and financial flexibility.

Inventory Turnover

The inventory turnover ratio exhibits notable fluctuations over the observed periods. It peaked at 45.2 in September 2022, indicating a very high efficiency in inventory management during that quarter. Before this peak, the ratio generally increased from 36.21 in December 2020 to 40.43 in June 2022, showing improving turnover performance. However, subsequent to the peak, the ratio decreased sharply to 32.36 in December 2022 and further declined to a low of 28.87 by September 2024. Following this decline, there was a recovery trend with the ratio rising again to 38.64 by September 2025. Overall, these trends suggest periods of both high and lower inventory movement rates, reflecting fluctuating operational efficiency or demand conditions.

Average Inventory Processing Period

The average inventory processing period (in days) inversely correlates with the inventory turnover ratio and ranges primarily between 8 and 13 days. The shortest processing period was 8 days recorded in September 2022, coinciding with the peak inventory turnover ratio, highlighting enhanced inventory velocity. Conversely, the longest processing periods around 12 to 13 days occurred in the quarters from April 2023 through September 2024, corresponding with the observed dip in inventory turnover. This pattern suggests slower inventory movement during this timeframe. Towards the end of the period, the processing days decreased back to 9, aligning with the recovery in turnover ratios and indicating improved efficiency in inventory processing.

Summary of Trends

The data illustrates a cyclical pattern in inventory management efficiency, with a significant high turnover and low processing period around mid-2022, followed by a period of reduced efficiency extending through late 2023 and most of 2024. The latter period features a longer inventory holding time and diminished turnover rates, which could point to challenges such as decreased sales velocity or overstocking. The improvement observed in late 2024 and through 2025 reflects a rebound in inventory performance, possibly attributable to operational adjustments or improved market demand. These insights suggest that inventory control and turnover have been subject to varying pressures, warranting continuous monitoring to maintain optimal inventory levels and turnover rates.

Receivables Turnover Ratio

The receivables turnover ratio demonstrates noticeable fluctuations over the observed periods. Starting at 10.85, the ratio peaked multiple times, reaching highs such as 21.47 and 19.87, indicating periods of efficient collection practices. However, there are recurring declines, notably down to as low as 10.46 by the end of the timeline. This oscillating pattern suggests variability in how promptly the company collects its accounts receivable, implying changing credit policies or customer payment behaviors across quarters.

Average Receivable Collection Period

The average collection period inversely mirrors the receivables turnover ratio, beginning with 34 days and descending to a low of 17 days at certain points, reflecting improved collection efficiency. Several intervals see a rise back to over 30 days, indicating slower collections in these quarters. The range varies from a low of 17 days to a high of 35 days, revealing inconsistent patterns in cash flow tied to receivables. These cycles may hint at seasonal factors, shifts in credit terms, or economic conditions influencing customer payment timing.

Overall Trend Analysis

The data reflects no linear progression but a repeating pattern of peaks and troughs over time for both ratios. The cyclical nature of the turnover ratio paired with the collection period indicates that periods of fast receivable turnover and short collection times alternate with slower, less efficient periods. The company's receivables management effectiveness varies, which could impact liquidity and working capital management. It is advisable to investigate the causes of these fluctuations to stabilize and optimize cash inflows.

Inventory Processing Period

The average inventory processing period generally remained stable around 9 to 11 days throughout most quarters, with a slight decline observed in mid-2021 and mid-2022. However, starting from late 2023, there was a noticeable increase, reaching up to 13 days in the third quarter of 2024, before gradually decreasing again to 9 days by the third quarter of 2025. This indicates some variability in inventory management efficiency, with occasional slower turnover towards the later periods.

Receivable Collection Period

The average receivable collection period exhibited considerable fluctuations over the observed timeframe. Initially, there was a downward trend from 34 days at the end of 2020 to a low of 17 days by the first quarter of 2023, signaling improved collection efficiency. Following this, the period increased again intermittently, peaking at 35 days in the third quarter of 2025. These changes suggest variability in accounts receivable management, with periodic challenges in accelerating cash inflows.

Operating Cycle

The operating cycle, defined as the sum of inventory processing and receivable collection periods, reflected the combined effects of the two metrics. It showed a general decline from 44 days in late 2020 to a low of 29 days by early 2023, indicating improved overall operational efficiency. Subsequently, the operating cycle lengthened again in later periods, reaching 44 days by the third quarter of 2025. This pattern underscores fluctuating operational conditions, where early efficiency gains were partially offset by later increases in inventory holding and receivables duration.

Summary

Overall, the financial data reveals periods of both improved efficiency and operational sluggishness. The company's inventory processing times and receivable collection periods varied over time, influencing the total operating cycle. Early improvements in managing receivables and inventory contributed to shorter cash conversion cycles, but these gains were not consistently maintained. The fluctuations in later periods highlight areas for potential operational focus to stabilize and optimize working capital management further.

Payables Turnover Ratio

The payables turnover ratio exhibits considerable fluctuation throughout the observed quarters. Initially, this ratio increased from 2.82 to a peak of 5.07 within the first year. It then declined to levels around 3.49 to 3.81 in subsequent quarters before rising again to values exceeding 4.5, notably in early 2023. The ratio shows a repeated pattern of sharp increases followed by moderate declines, indicating varying efficiency in settling payables over time. Towards the latest periods, the ratio slightly moderates, ranging between approximately 3.16 and 4.33.

Average Payables Payment Period

The average payables payment period generally moves inversely to the payables turnover ratio, ranging from 72 to 129 days. It starts at a longer duration of 129 days, decreases to 72 days, and then experiences intermittent rises and falls. Notably, the payment period extends above 100 days multiple times, indicating periods where the company took longer to pay its suppliers. Periods of reduced payment days, closer to 72-80 days, coincide with quarters exhibiting higher payables turnover ratios.

Relationship Between the Two Metrics

As anticipated, the payables turnover ratio and the average payables payment period demonstrate an inverse relationship; high turnover ratios correspond with shorter payment periods, and vice versa. This oscillation suggests that the company's payment practices vary significantly between quarters, possibly due to changes in working capital management strategies, supplier terms, or seasonal operational demands.

Overall Insights

The data reflect an inconsistent approach to managing payables, with the company alternating between faster and slower payment cycles. Periods of high turnover and short payment durations may signal improved liquidity or more stringent cash management, while longer payment periods coupled with lower turnover could imply extended credit terms or cash preservation efforts. The observed variability indicates a dynamic payables management policy responsive to internal or external financial conditions rather than a stable, consistent pattern.

The analysis of the quarterly financial indicators reveals several trends related to the company's operational efficiency and working capital management over the reported periods.

Average Inventory Processing Period

The average inventory processing period generally fluctuates between 8 to 13 days throughout the periods. Early values hover around 9 to 11 days, indicating relative stability. There is a slight increasing trend toward the end of the timeline with peaks at 13 days (September 2024) before decreasing again to 9 days by September 2025, suggesting periodic adjustments in inventory turnover rates.

Average Receivable Collection Period

This period exhibits more volatility compared to inventory processing. It initially declines sharply from 34 days to 18 days within the first three quarters, improving collection efficiency. However, subsequent quarters show irregular fluctuations between 17 and 35 days, ending on a higher note at 35 days in September 2025. These variations indicate changes in credit policy or customer payment behaviors affecting cash inflows.

Average Payables Payment Period

The average payables payment period shows a high and variable pattern, ranging broadly from 72 to 129 days. Early quarters show a decrease from 129 to 72 days, suggesting faster payments to suppliers initially. Afterward, the period oscillates with intermittent increases, peaking again near 120 days in September 2024, reflecting a possible strategic delay in payments to manage cash outflows.

Cash Conversion Cycle (CCC)

The cash conversion cycle remains consistently negative throughout all periods, indicating that the company maintains a net working capital cycle where payables turnover outpaces the sum of inventory processing and receivables collection periods. The CCC ranges between -87 and -43 days, displaying fluctuations that mirror changes in the underlying components. This negative CCC suggests efficient use of supplier financing and strong liquidity management, although variations hint at shifting operational dynamics.

Overall, the data suggests a company maintaining effective control over its cash cycle but experiencing some volatility in receivables and payables periods. The negative and fluctuating cash conversion cycle highlights periodic operational adjustments but consistent emphasis on leveraging supplier credit. Inventory management remains relatively stable with minor variations. These trends embody adaptive working capital management responsive to market or internal conditions.
