Sanmina's stock surged 14.84% in pre-market trading on Tuesday, marking a significant upward movement for the electronics manufacturing services provider.

The dramatic price increase was driven by the company's impressive fiscal second-quarter results, which soundly beat analyst expectations. Sanmina reported adjusted earnings per share of $3.16, significantly exceeding the consensus estimate of $2.40. Revenue more than doubled year-over-year to $4.01 billion, also surpassing the $3.29 billion analyst forecast.

Management attributed the strong performance to ZT Systems revenue that "significantly exceeded expectations," driven by strong execution and customer demand. Additionally, Sanmina's board authorized a new $600 million share repurchase program. The company also provided optimistic guidance, forecasting third-quarter adjusted EPS between $2.55 and $2.85 (versus $2.53 consensus) and raising its full-year 2026 adjusted EPS outlook to $10.75 to $11.35 (versus $10.02 consensus).
