Sanmina Surges 20% on Monster Q4 Beat: Buy or Fade?
Sanmina (SANM) crushed Q4 estimates with EPS of $4.43 vs. $3.33 expected and revenue of $3.86B. Here's what traders need to know.
Key Points
- Sanmina posted non-GAAP EPS of $4.43 versus the $3.33 consensus — a 33% beat — on revenue of $3.858 billion against estimates of $3.547 billion.
- Full fiscal year 2026 revenue hit $14.53 billion, up 79% year-over-year, as AI-driven demand for advanced manufacturing surged through the supply chain.
- Traders should watch whether SANM can hold its 20%-plus gap at the open, and whether FY2027 guidance of ~27% revenue growth draws fresh institutional accumulation.
Sanmina delivered the most decisive earnings beat of the cycle Monday evening: non-GAAP EPS of $4.43 crushed the $3.33 consensus by a full $1.10, while revenue of $3.858 billion ran $310 million ahead of the $3.547 billion estimate. The stock jumped more than 20% in after-hours trading and was holding those gains heading into Tuesday's pre-market session — a move that, if sustained at the open, would add roughly $2 billion to the company's market capitalization in a single session.
The Numbers Behind the Gap
The headline beat was striking on its own, but the full-year figures are what separate this from a one-quarter fluke. For fiscal 2026, Sanmina reported total revenue of $14.53 billion — a 79% increase from fiscal 2025 — while non-GAAP diluted EPS rose to $13.28 from $6.04 the prior year, representing 120% bottom-line growth over twelve months. That is not incremental improvement; that is a business that has fundamentally repriced its revenue base.
The revenue acceleration reflects what has been building in the contract electronics manufacturing space since late 2024: a structural shift in customer behavior as hyperscalers, defense contractors, and AI infrastructure buildouts pulled forward massive procurement orders. Sanmina, which manufactures everything from printed circuit board assemblies to complex integrated systems for the defense, industrial, and medical sectors, was positioned directly in the path of that spending surge. When the AI infrastructure cycle hit peak velocity in fiscal 2026, Sanmina absorbed orders that would have been unthinkable on its prior cost base. Management has not disclosed a customer-by-customer revenue breakdown, but the implied math — a 79% topline jump — suggests large, concentrated contract wins rather than broad-based volume growth across its entire customer roster.
The margin picture tells a more nuanced story. Non-GAAP EPS grew 120% year-over-year, well ahead of the 79% revenue growth, which means operating leverage is real and not just a volume artifact. Contract manufacturers typically operate on razor-thin margins in the 2% to 4% net range, so double-digit percentage EPS growth on top of a 79% revenue gain implies Sanmina either repriced its contracts meaningfully upward or achieved material cost efficiencies — or both. Traders should read the full earnings transcript for color on gross margin trajectory, because if margins begin compressing as the company absorbs higher labor or component costs in fiscal 2027, the premium the market is now assigning could erode faster than the revenue line might suggest.
What the Guidance Is Actually Saying
Forward guidance is where management either confirms the thesis or quietly signals caution through conservative framing. Sanmina's FY2027 outlook projects revenue growth of approximately 27% at the midpoint, with non-GAAP diluted EPS growth of approximately 24% — both numbers that, if delivered, would make fiscal 2027 another outlier year by any historical standard for the contract manufacturing sector. The fact that EPS growth guidance slightly trails revenue growth guidance is a yellow flag worth monitoring: it suggests management may be anticipating some margin compression as it scales further, potentially absorbing higher input costs or investing in capacity to support the revenue ramp.
For context, 27% revenue growth on a $14.53 billion base would put fiscal 2027 revenue at roughly $18.5 billion. That is a number that places Sanmina firmly in the conversation alongside larger contract manufacturing peers like Flex Ltd. and Jabil, both of which trade at higher revenue multiples due to their diversified customer bases and global footprint. If Sanmina sustains execution into the first two quarters of fiscal 2027, the re-rating argument becomes structural rather than event-driven — and the 20% one-day pop might look conservative in hindsight.
The board has not announced a share repurchase authorization alongside these results, which is notable. The absence of a buyback signal is not alarming given the apparent capital deployment priorities, but it does mean the near-term price support will need to come from fundamental buyers rather than management engineering earnings-per-share through float reduction. That changes the technical dynamic at today's open: without a buyback floor, early sellers who bought the after-hours spike could apply meaningful pressure if momentum fades in the first hour of trading.
What Traders Watch Next
The critical variable for SANM over the next 30 days is not the earnings report itself — that story is now priced in — but rather whether the fiscal Q1 2027 setup can sustain the narrative. The company's fiscal year begins in October, meaning the first quarter of fiscal 2027 is already underway as of today, November 10. Any commentary from management about October order trends, backlog composition, or customer spending visibility will function as an early read on whether the 27% growth guide has cushion or is baked tight.
Technically, the stock will face a critical test at today's opening print. Stocks that gap up 20% or more on earnings typically see one of two patterns in the first 90 minutes: either institutional buyers step in to accumulate on any pullback, confirming the move as a re-rating event, or early momentum sellers and short-term options traders harvest the gap and push the stock back toward the prior closing range. The level to watch on the downside is the pre-earnings close, which serves as the line in the sand between a confirmed breakout and a failed gap. On the upside, if SANM trades above its after-hours high with volume confirmation in the first hour, that would signal institutional conviction rather than retail enthusiasm driving the move.
Longer-dated investors should anchor to the FY2027 EPS guidance midpoint. If management guided approximately 24% EPS growth off the $13.28 fiscal 2026 base, the implied FY2027 non-GAAP EPS lands near $16.47. At the pre-earnings stock price, SANM was trading at a mid-single-digit forward multiple — deeply discounted relative to peers, which is exactly the compression that makes a 20% single-session re-rating intellectually coherent. The next scheduled catalyst is the fiscal Q1 2027 earnings report, expected in late January or early February 2027. Between now and then, the tape will be the signal.
