Driven by increased net sales, higher fixed costs and customer mix shift; approximately 89% variable and 88% material/component costs.

Margins: Gross margin remained flat at 10.1% despite 28% revenue growth, as fixed cost increases and unfavorable customer mix shifts offset pricing gains. Operating margin compressed 60 basis points to 4.7% primarily due to $12.9M in accelerated stock compensation from executive retirements.

Free cash flow turned negative at -$35.3M YTD (vs. +$56.8M prior year) driven by $297.5M inventory build and higher receivables, despite $39M operating cash flow.
