Jabil Circuit (JBL) shares surged 5.48% in pre-market trading on Wednesday, following the release of the company's fiscal third-quarter results and an upward revision to its full-year outlook.

The significant pre-market gain is attributed to the electronic-component manufacturer reporting better-than-expected quarterly earnings and revenue, driven by robust demand for artificial intelligence infrastructure. The company's CEO, Mike Dastoor, stated that "AI infrastructure demand remains extremely strong," leading to a "meaningfully higher" full-year AI-related revenue outlook.

Jabil posted adjusted earnings per share of $3.16 for the quarter, surpassing analyst estimates of $3.10. Revenue climbed to $8.75 billion, also beating expectations. Furthermore, the company raised its fiscal 2026 guidance, now expecting adjusted earnings per share of $12.70 and revenue of approximately $35 billion, up from previous forecasts, citing strong performance across its diversified business segments including automotive and connected living.
