The data indicates a consistent upward trend in KLA-Tencor Corporation's days of inventory on hand (DOH) over the analyzed period. Starting at approximately 206.37 days as of September 30, 2020, the DOH exhibited minor fluctuations but remained relatively stable through 2020 and most of 2021, averaging around 208 days.
However, beginning in mid-2021, a gradual but steady increase in DOH is observable. By the end of June 2021, the figure was approximately 207.42 days, rising slightly further to 211.15 days by September 2021. The upward movement continued into 2022, reaching over 230 days by September 2022 and exceeding 224 days at year's end.
The trend accelerated considerably in 2023, with DOH surpassing 237 days in March, then climbing sharply to approximately 248.92 days in June, and reaching 266.20 days by September. The increase persisted through the end of 2023 and into the first half of 2024, where DOH figures approached nearly 286.90 days by June 2024 before slightly declining to 279.48 days in September 2024.
Between late 2024 and mid-2025, the DOH estimates exhibit a gradual decrease, with figures moving from around 258 days in December 2024 down to approximately 246.73 days as of June 2025. This suggests a slight improvement in inventory management efficiency over this recent period.
Overall, the data portrays a significant lengthening of inventory holding periods over multiple years, with a peak in late 2023 and early 2024, followed by a modest reduction. This trend may implicate shifts in inventory strategies, supply chain management, or changes in the market demand environment. The sharp increase in DOH during 2022 and 2023 warrants further analysis to assess underlying causes such as inventory buildup, longer production cycles, or strategic stockpiling.
