Total inventory levels exhibit a consistent and significant upward trajectory between 2018 and 2022. From a baseline of 55,641 thousand US dollars in 2018, total inventories escalated to 338,752 thousand US dollars by the end of 2022, representing an overall increase of approximately 508%. This expansion indicates a substantial increase in the working capital allocated to inventory management over the five-year period.

Raw Material Accumulation

Raw materials represent the most significant area of growth within the inventory portfolio, rising from 26,119 thousand US dollars in 2018 to 172,758 thousand US dollars in 2022. A pronounced acceleration is observed between 2020 and 2022, where values more than doubled, suggesting a strategic increase in the stockpiling of primary inputs.

Work in Progress and Finished Goods Trends

Work in progress experienced a sharp increase from 13,784 thousand US dollars in 2018 to 96,558 thousand US dollars in 2022, with a particularly steep rise observed between 2021 and 2022. Finished goods also grew steadily, moving from 15,738 thousand US dollars to 69,436 thousand US dollars, though the growth rate in this category was more moderate compared to raw materials and work in progress.

Compositional Shift in Inventory

The relative distribution of inventory has shifted toward the earlier stages of production. In 2018, raw materials constituted approximately 47% of total inventory, increasing to approximately 51% by 2022. Conversely, the proportion of finished goods decreased from roughly 28% of the total inventory in 2018 to approximately 20% in 2022. This pattern indicates that inventory growth is being driven primarily by the acquisition of raw materials and the expansion of active production rather than the accumulation of completed products.
