Jabil (JBL) Falls 7% Despite Q4 Beat: Why Shares Slid

Jabil shares fell more than 7% after a fiscal fourth-quarter beat and a $44.5 billion fiscal 2027 outlook, as margin timing and capacity spending weighed.

What Did Jabil Report for the Fourth Quarter?

Jabil reported fourth-quarter revenue of $10.6 billion against $8.3 billion a year earlier, ahead of the $9.69 billion consensus. Core diluted EPS of $4.40 beat the $4.06 estimate. GAAP diluted EPS was $3.76. Core operating income reached $675 million, a core operating margin of 6.4%.

For the full fiscal year, net revenue rose 21% to $36.0 billion and core EPS reached $13.09. Core operating margin expanded 40 basis points to 5.8%. Adjusted free cash flow totaled $1.532 billion, and the company repurchased $1.06 billion of stock. Capital expenditure for the year was $628 million.

CEO Mike Dastoor said the company delivered a quarter that exceeded its own expectations, citing strength in AI infrastructure and diversified end markets.

What Is Jabil Guiding for Fiscal 2027?

Jabil expects fiscal 2027 revenue of $44.5 billion, up 24%, with core operating margin of 6.1% and core EPS of $17.55, up 34%. Adjusted free cash flow is projected at about $1.6 billion.

The Intelligent Infrastructure segment is expected to grow 43%. AI-related revenue is forecast at about $22.1 billion, up 54%. Cloud and data center infrastructure revenue is forecast at about $17.5 billion, up 52%. Management also pointed to growth in automotive, healthcare, energy infrastructure, defense and aerospace, and warehouse and retail automation.

Why Did Jabil Shares Fall Despite the Beat?

Shares fell because the guidance shape and spending plans overshadowed the headline numbers. Three factors stood out.

First, near-term guidance was softer than the quarter just reported. First-quarter core EPS is guided at $3.80 to $4.20, a midpoint of $4.00 against $4.40 in the fourth quarter. The midpoint for core operating income of $592 million to $652 million implies about $622 million, below the $675 million just delivered. Management indicated that margins and earnings would be weighted toward the back half of fiscal 2027.

Second, the company plans to add roughly 4 million square feet of manufacturing capacity. The buildout raises execution risk, since it depends on customer ramps arriving on schedule.

Third, valuation and positioning. The stock entered the report up about 23.7% year to date, though still about 23% below its June 2026 high of $385.63. Five sessions earlier it had gained 4.8% after Akamai (AKAM) authorized Jabil to buy about $1.7 billion in memory components tied to an AI infrastructure buildout. Management also flagged memory supply constraints, which can delay shipments and shift revenue between quarters. The stock has moved more than 5% on 25 occasions over the past year, which magnifies reactions to any perceived disappointment.

How Does the Reaction Fit the Wider AI Trade?

The reaction fits a pattern across AI stocks, where a beat is already priced in and investors focus on timing of margins, capital intensity and supply bottlenecks. Jabil sits in the physical layer of the AI buildout, assembling servers, networking gear and power systems for hyperscale customers, so its results track data center spending. Five customers are each expected to generate more than $1 billion in AI-related revenue.

The guidance implies that demand is not the constraint. Component availability, factory space and the pace of margin recovery are.

Strategic Context

Jabil's mix is shifting toward higher-growth infrastructure work while it keeps regulated end markets such as healthcare, aerospace and defense. A 6.1% core margin target for fiscal 2027 represents 30 basis points of expansion on far larger revenue. The $1.6 billion free cash flow target is only modestly above fiscal 2026's $1.532 billion, reflecting heavier investment in capacity and working capital as revenue scales.

Outlook

Jabil enters fiscal 2027 with guidance above consensus on revenue and earnings, a $44.5 billion revenue target and AI-related revenue forecast to exceed $22 billion. The first-quarter guide of $10.6 billion to $11.4 billion in revenue will be the first test of whether margins build through the year as planned. Memory supply and the pace of the 4-million-square-foot capacity expansion are the variables to watch.
