Why is Sanmina stock surging today?

Sanmina Corporation stock surged 20.4% in after-hours trading after the electronics manufacturing services giant reported fiscal fourth-quarter results that significantly exceeded analyst expectations across every major metric.

Adjusted earnings per share came in at $4.43, beating the Wall Street consensus of $3.27 by $1.16 — a roughly 35% upside surprise — while quarterly revenue of $3.86 billion topped the $3.48 billion estimate by nearly 11%. For the full fiscal year 2026, revenue reached $14.53 billion, up 79% year over year, with adjusted diluted EPS more than doubling compared to the prior year.

The forward outlook proved equally powerful in driving the after-hours move. Management guided first-quarter fiscal 2027 adjusted EPS of $3.50 to $3.85, with the midpoint sitting 25% above the analyst consensus of $2.95, and revenue guidance of $3.80 billion to $4.10 billion, with the midpoint approximately 11% above expectations. For the full fiscal year 2027, the company projected revenue of $17.5 billion to $19.5 billion and EPS of $15.50 to $17.50, implying roughly 27% revenue growth and 24% earnings growth at the midpoint. Chairman and CEO Jure Sola called it "a transformative year," highlighting the successful integration of the ZT Systems business and strengthened positioning in the Cloud and AI Infrastructure end market.

The broader market provided little directional help, with the S&P 500, Dow Jones, and NASDAQ all finishing the regular session essentially flat. There were no major macro data releases or central bank announcements that materially influenced the tape, underscoring that today’s sharp move in SANM was entirely driven by company-specific catalysts. The stock had been down significantly from its 52-week high of $288.68, trading near multi-month lows heading into the print, which amplified the relief rally as the results came in well ahead of even the most optimistic scenarios.

Taken together, a rare combination of a massive earnings beat, guidance that dwarfed consensus estimates, strong free cash flow generation of $541 million for the fiscal year, and continued share repurchases gave investors multiple reasons to aggressively re-rate the stock higher in after-hours trading, with shares reaching $180.09 after having opened the regular session at $137.52.
