Jabil reaches its September 30 fiscal year-end update with stronger revenue, earnings, and cash generation, but that momentum has also raised the evidence bar. Fiscal third-quarter revenue increased 11.8% to $8.751 billion, GAAP operating income increased 10.4% to $445 million, and GAAP diluted earnings per share advanced 27.6% to $2.59. The latest quarter therefore showed progress across several operating measures rather than one favorable data point.
Intelligent Infrastructure is central to the next test. The segment produced $4.169 billion of fiscal third-quarter revenue with a 6.1% margin, compared with $3.433 billion and a 5.3% margin a year earlier. Management described AI infrastructure demand as extremely strong. The September update can help clarify whether that demand is still supporting both growth and profitability as Jabil outlines its fiscal 2027 priorities.
Cash conversion strengthens the operating case, but working capital keeps the interpretation balanced. Nine-month adjusted free cash flow increased 21.9% to $991 million. Inventory, however, reached $5.933 billion at May 31, up 26.7% from August 31, 2025, while the current ratio was 0.98. Those periods are not directly comparable growth windows, yet the combination still makes inventory conversion an important check on the quality of current demand. That gap does not negate the cash progress, but it makes balance-sheet efficiency a necessary companion to segment growth.
The September 30 release is scheduled before the market opens, followed by an 8:30 a.m. ET call. The most useful evidence will be the breadth of infrastructure demand, full-year cash delivery, the pace of inventory conversion, and management's fiscal 2027 priorities. Customer concentration also remains relevant because the five largest customers represented about 36% of nine-month revenue.
