Sanmina Corporation Posts 20% Surge After Q4 Earnings Beat

NEW YORK, November 10 —

Sanmina Corporation (SANM) surged 20% after hours after Q4 fiscal 2026 beat consensus on both revenue and EPS, with Q1 guidance above estimates sealing the move.

9.2x P/E Against 84% Revenue Growth Is the Underweighted Signal

Sanmina Corporation (SANM) entered this print with a multiple that did not match its growth rate, and the after-hours pop has not fully closed that gap. At 9.2x forward earnings on a $14.5bn TTM revenue base growing 84% YoY, the valuation screens far cheaper than its growth trajectory would typically command. That compression is either a genuine opportunity or a market signal that the revenue pace is not sustainable, and tonight's Q1 guidance was management's most direct answer to that skepticism.

Guidance Did the Work That Sustains a Re-Rating

A single-quarter beat generates one-day momentum. The more durable signal here is management issuing Q1 guidance above street estimates immediately after a blowout quarter. That sequencing implies confidence in order visibility, not just one strong close to fiscal 2026. When a company guides above consensus the same night it beats, it is separating a trade from a thesis, and the sharp gap-up visible in the chart reflects that distinction.

Negative Free Cash Flow Is the Bear Case Embedded in the Bull Story

The number that complicates everything: -$355mn in TTM free cash flow on $14.5bn in revenue. At that growth rate, cash consumption can reflect working capital expansion rather than operational weakness, but that explanation has a shelf life. If FCF does not turn positive over the next two quarters, the low multiple stops looking like a compression anomaly and starts looking like a price signal. Running that scenario through the DCF calculator tightens the implied margin of safety quickly.

One Print Will Confirm or Kill the Re-Rating

The $5.59 trailing EPS against a $149.64 close implies the market is already pricing in continued earnings expansion. That is the thesis in one line. The number that breaks it is specific: Q1 fiscal 2027 EPS coming in below the guidance range Sanmina set on tonight's call. Watch that figure at the next earnings call, not the annual outlook or qualitative commentary. Everything else is noise until then.
