Sanmina (NASDAQ: SANM) reported fiscal fourth-quarter 2026 revenue of $3.86 billion, up approximately 84% year over year, in its
November 9 earnings release. Non-GAAP diluted earnings per share reached $4.43, compared with GAAP diluted EPS of $2.14, as the manufacturer expanded its cloud and AI infrastructure business.
The useful question goes beyond the headline growth rate. Sanmina's results combine the addition of ZT Systems with growth in its existing operations, while its fiscal 2027 outlook points to continued expansion at a lower operating margin than the latest quarter. Separating those components provides a clearer picture of the business entering the new year.
Key Takeaways
Q4 revenue and non-GAAP EPS exceeded the company's previous guidance ranges.
The revenue increase reflects both ZT Systems and growth in Core Sanmina, rather than a single source of AI demand.
Fiscal 2027 guidance supports further expansion, while the margin outlook calls for a separate assessment of profitability.
Q4 Results Exceeded Sanmina's Own Forecast
Sanmina's
Q4 earnings presentation shows previous quarterly revenue guidance of $3.3 billion–$3.6 billion and non-GAAP EPS guidance of $3.05–$3.35. The reported results exceeded both upper limits, demonstrating stronger execution than management had previously projected.
These comparisons establish the size of the improvement without relying solely on year-over-year growth. They measure performance against company guidance, which should remain distinct from any comparison with analyst consensus. GAAP and non-GAAP earnings also need to be compared on a consistent basis.
Growth Extended Beyond the ZT Systems Acquisition
Core Sanmina revenue rose 41.9% year over year to approximately $2.97 billion in Q4, exceeding its outlook. ZT Systems contributed $884 million, in line with expectations. That breakdown shows that the quarter's stronger-than-guided revenue was not simply the result of the acquired business outperforming its forecast.
It also explains why the consolidated 84% increase should not be described entirely as organic growth or AI revenue growth. Sanmina serves multiple end markets, and the company's Core Sanmina reporting category is not automatically equivalent to a formally reconciled organic growth measure. The disclosed breakdown supports a more precise conclusion: acquisition-driven expansion was accompanied by substantial growth elsewhere in the company.
The AI Opportunity Is Becoming a Manufacturing Delivery Story
Sanmina reported $5.35 billion in fiscal 2026 Cloud & AI Systems revenue and expects $7.5 billion–$9.0 billion in fiscal 2027. It also said Helios products had begun shipping. These disclosures connect the AI opportunity to manufacturing activity and a defined revenue outlook.
Cloud & AI Systems is a subset of Sanmina's broader Cloud & AI Infrastructure end market, incorporating ZT Systems and other platforms, products and services. Keeping those definitions separate avoids overstating either the size of the category or the contribution of the acquisition.
Sanmina's position in this spending cycle is also different from that of an AI cloud operator. Its opportunity centers on manufacturing and delivering hardware and related services. Growth across suppliers and cloud providers may reflect connected activity within the same infrastructure investment cycle, so their revenues should not simply be added together as separate measures of new AI spending.
Fiscal 2027 Growth Does Not Assume Q4 Margins Persist
For fiscal 2027, Sanmina expects revenue of $17.5 billion–$19.5 billion and non-GAAP diluted EPS of $15.50–$17.50. The company reported fiscal 2026 revenue of $14.53 billion, providing a clear base for assessing the scale of the projected expansion.
The profitability assumption deserves equal attention. Q4 non-GAAP operating margin was 9.0%, while fiscal 2027 guidance is 7.0%–7.5%. The outlook therefore supports further growth without assuming that the latest quarterly margin becomes the full-year norm. The difference alone does not establish a cause such as pricing pressure or weaker demand.
The next useful evidence will be whether manufacturing deliveries support the revenue outlook and whether operating profitability remains consistent with guidance. Revenue growth, margins and earnings should be assessed together: a larger manufacturing business can generate higher total profit even when its percentage margin is below an unusually strong quarter.
FAQ
What does Sanmina do in AI infrastructure?
Sanmina provides manufacturing solutions, products and services used in cloud and AI infrastructure. Its role includes delivering hardware systems rather than operating the same business model as an AI cloud service provider.
Was Sanmina's 84% revenue growth entirely organic?
No. Consolidated revenue includes the acquired ZT Systems business as well as Core Sanmina. The company disclosed growth in Core Sanmina separately, allowing readers to distinguish those contributions.
What is the main question for fiscal 2027?
The issue is whether the projected expansion can be delivered with the profitability management expects. Sales growth alone does not establish the earnings contribution of additional manufacturing work.
