Net of customer inventory deposits ($1.385 billion), net inventory days were approximately 68 days, remaining above Jabil's internal target range and reflecting the inventory absorption required for rack-level system integration. Management believes these will come down, and our Deep Dive analysis supports that. Additionally...
