Is SANM a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for Sanmina Corporation (SANM) rests on AI and cloud infrastructure ramp: The ZT Systems business added roughly $1.88 billion of revenue in a single quarter and pushed total Q2 fiscal 2026 revenue to about $4.0 billion, up around 102% year over year. Revenue (FY2026 guidance) is ~$13.7B to $14.3B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Sanmina operates on thin EMS margins (non-GAAP operating margin around 6%), so small execution errors or pricing pressure can meaningfully affect profits. Whether SANM is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
Sanmina Corporation, founded in Silicon Valley in 1980 and headquartered in San Jose, California, is a Fortune 500 global provider of integrated manufacturing solutions, components, and repair, logistics and after-market services. It serves original equipment manufacturers (OEMs) across industrial and energy, medical, defense and aerospace, automotive, communications networks, and cloud and AI infrastructure, running two businesses: Integrated Manufacturing Solutions and Components, Products and Services. It employs roughly 35,000 people and serves customers from around 20 countries. The investment picture changed sharply in late 2025 when Sanmina completed its roughly $3 billion acquisition of the ZT Systems data-center infrastructure manufacturing business from AMD, adding a business with an annual revenue run-rate near $5 to $6 billion and a preferred-partner relationship to build AMD cloud rack and cluster-scale AI systems. That deal roughly doubled quarterly revenue and repositioned Sanmina as a large cloud and AI infrastructure manufacturer. The result is a company with far higher revenue and a richer growth narrative than the traditional contract manufacturer it was, paired with the thin margins, customer concentration, and integration risk that come with the electronics-manufacturing-services model.
What's the case for buying SANM?
1. AI and cloud infrastructure ramp
The ZT Systems business added roughly $1.88 billion of revenue in a single quarter and pushed total Q2 fiscal 2026 revenue to about $4.0 billion, up around 102% year over year. Management raised full-year fiscal 2026 revenue guidance to roughly $13.7 to $14.3 billion, driven largely by demand for AI server and data-center infrastructure manufacturing.
2. AMD partnership and preferred-manufacturer status
As part of the ZT Systems deal, Sanmina became a US-based preferred new product introduction (NPI) manufacturing partner for AMD cloud rack and cluster-scale AI solutions. This gives Sanmina an anchor customer relationship in a fast-growing end market and a differentiated position in US-based AI infrastructure assembly.
3. Diversified core EMS base
Beyond AI, the core Sanmina business (industrial, medical, defense and aerospace, automotive, and communications) grew around 7% year over year and provides steadier, less cyclical demand than pure consumer electronics. This diversification is intended to cushion the company against swings in any single end market.
4. Capital return and balance-sheet use
The board authorized an additional $600 million share repurchase program with no expiration date, signaling management confidence and a lever for per-share value even as the company digests a large acquisition. How aggressively buybacks proceed alongside integration spending is a key watch item.
What are the risks to SANM?
Sanmina operates on thin EMS margins (non-GAAP operating margin around 6%), so small execution errors or pricing pressure can meaningfully affect profits. The ZT Systems business creates heavy revenue concentration tied to AI and data-center capital spending, which is cyclical and could slow if hyperscaler or AMD-related demand cools. Integration of a multi-billion-dollar acquisition carries operational and financial risk, and the AMD relationship makes results partly dependent on one large partner. The stock now trades at a large premium to its long-run average valuation, so disappointment relative to lofty AI expectations could pressure the shares. Broader risks include supply-chain disruption, customer concentration, and macro cyclicality across its industrial and communications markets.

How do you decide if SANM is a buy?
Rather than asking whether SANM is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold SANM indirectly through an index or sector ETF before adding more.
