Additional liquidity measure

The cash conversion cycle of PDF Solutions Inc. has fluctuated in recent years, with a noticeable improvement in the cycle for the year ended December 31, 2022. In 2023, the company's cash conversion cycle increased to 80.77 days from 54.93 days in 2022 but remained lower than the 85.87 days reported in 2021, indicating that the company took longer to convert its investments in inventory back into cash during the latest period.

Although the cycle decreased from 2020 to 2022, the current increase may suggest potential challenges in managing inventory, receivables, and payables efficiently. The longer cash conversion cycle could indicate inefficiencies in inventory management or a slowdown in collecting receivables, both of which can tie up capital and impact liquidity.

Further analysis of the components of the cash conversion cycle, such as Days Sales Outstanding (DSO), Days Inventory Outstanding (DIO), and Days Payables Outstanding (DPO), would provide more insights into the specific areas affecting PDF Solutions Inc.'s working capital management and overall operational efficiency.
