Start with size metrics. Working capital as a percentage of sales tells you how much funding each dollar of revenue consumes. Compare Thistlebrook's 18% to industry peers. If they run at 18% and peers average 12%, they have roughly 6% of revenue in excess investment.

Next, decompose the cash conversion cycle into days inventory outstanding, days sales outstanding, and days payable outstanding. Each component reveals a distinct lever. Rising DIO signals inventory buildup, potentially obsolescence. Rising DSO signals collection weakness or aggressive revenue recognition. Falling DPO means suppliers are tightening terms.

Then examine seasonality. Retailers like Thistlebrook may build inventory ahead of peak season, making quarter-end snapshots misleading. Average-balance and mid-period measurements give a truer picture.

Finally, assess financing structure. Permanent working capital (the minimum always required) should be funded with long-term sources. Temporary working capital (seasonal swings) belongs on short-term lines. Mismatches create refinancing and liquidity risk.

Analyst Darius Whitmore notes Thistlebrook's DIO rose from 58 to 84 days while DPO fell from 45 to 32. Net operating cycle expanded by 39 days, consuming $48M additional funding. He flags this as a red flag and investigates inventory obsolescence and supplier relationships.

Good working capital analysis triangulates ratios, peer benchmarks, trend lines, and qualitative context.
