AI servers now drive Sanmina’s upside and risk

Q2 FY26 revenue was $4.0 billion, well above management’s outlook, helped by pulled-in AI compute shipments.
Management raised FY26 guidance to $13.7 billion to $14.3 billion of revenue and $10.75 to $11.35 of non-GAAP EPS.
Cloud and AI infrastructure made up 69% of Q2 FY26 revenue, so Sanmina is now much more tied to data center spending.
The ZT Systems deal is working so far, and management says it is increasingly confident in $16 billion plus revenue for FY27.
The main bear case is concentration: a delay or spending pause by a large cloud customer could hit results fast.

01 Running thesis

AI pull-in proves execution, raises the bar

Sanmina’s story changed after the ZT Systems acquisition closed. ZT gives Sanmina a much larger role in building AI data center systems, the hardware used by cloud companies to run advanced computing workloads. In Q2 FY26, Sanmina delivered $4.0 billion of revenue because a customer pulled forward accelerated compute shipments that had been expected later in the year.

That matters because this is not easy work. Sanmina has to build, test, and ship complex AI platforms at scale. The Q2 beat makes the bull case more believable: the ZT integration is off to a strong start, demand is showing up, and management raised FY26 guidance to $13.7 billion to $14.3 billion of revenue.

The same event also sharpens the risk. A pull-in helps today, but it can make the next quarter harder. Management guided Q3 FY26 revenue of $3.2 billion to $3.5 billion and non-GAAP EPS of $2.55 to $2.85, so investors need to watch whether demand keeps moving forward or simply came early.

Finn’s view is balanced. Growth and performance look better after Q2, but the company is now more exposed to a few large cloud buyers and to the timing of AI hardware ramps. The stock’s valuation score is decent, not cheap enough to ignore that risk.

Apr 2026▲Sanmina beat Q2 FY26 expectations as accelerated compute shipments for ZT Systems were pulled into the quarter. Management raised FY26 guidance and said it is increasingly confident in $16 billion plus revenue for FY27.

Jan 2026▲The first quarter with ZT Systems showed early validation of the deal. Communication Networks and Cloud and AI Infrastructure reached 62% of revenue, and management reaffirmed the goal to double revenue to more than $16 billion.

Nov 2025▲The ZT Systems acquisition closed, and management pulled forward its revenue doubling target from a three-year plan to a two-year plan. The legacy business was still expected to grow in the high single digits.

Jul 2025▲Sanmina beat Q3 FY25 revenue and EPS expectations, helped by Communications and Cloud strength. The pending ZT Systems acquisition added a major AI data center growth path, along with larger integration risk.

Apr 2025→Q2 FY25 confirmed recovery in Communications and Cloud, but full-year revenue growth guidance narrowed to 6% to 8%. A customer program delay and tariff uncertainty made the second-half setup more measured.

Jan 2025▲Q1 FY25 beat expectations and moved the story from cautious recovery to high single-digit expected full-year revenue growth. Management also said customer inventory overhang was nearly worked down.

Nov 2024→Q4 FY24 beat revenue and EPS expectations, but Q1 FY25 guidance pointed to flat to slightly lower sequential revenue. The recovery looked real, but not yet smooth.

02 Business model

A contract builder with deeper customer ties

Sanmina makes money by building complex electronics and full systems for original equipment makers, known as OEMs. These customers design products, while Sanmina handles manufacturing, testing, supply chain work, and sometimes direct order fulfillment.

The company’s main strength is trust in hard markets. Medical, defense, aerospace, cloud, and industrial customers often need strict quality control and long product lives. Once Sanmina is inside a program, switching suppliers can be costly and risky for the customer.

The ZT Systems acquisition changes the scale of the model. Management said ZT had a current annual revenue run rate of about $5 billion to $6 billion when the deal closed, and now says Sanmina can reach $16 billion plus of revenue in FY27. That is a big step up from the legacy business.

The tradeoff is working capital and concentration. AI server programs can require lots of parts, fast build schedules, and tight coordination with a few customers. If those customers slow orders, Sanmina can feel it quickly.

03 Product portfolio

What Sanmina builds

Cash cow

Integrated Manufacturing Solutions

This is the core build-and-ship business. It includes printed circuit board assembly, full system assembly, testing, and order fulfillment for OEM customers.

Growth engine

AI data center systems

ZT Systems gives Sanmina a bigger place in cloud and AI infrastructure. Q2 FY26 strength came from accelerated compute shipments, and management is investing for next-generation platform ramps in late calendar 2026.

Steady

Components, Products, and Services

CPS includes higher-margin parts such as advanced printed circuit boards, backplanes, cable assemblies, optical and RF microelectronics, and precision machining. These parts can deepen Sanmina’s role in complex customer systems.

Steady

Defense, aerospace, and medical manufacturing

These markets value quality, compliance, and long-term supply. They help balance the faster but lumpier cloud and AI business.

Option

Industrial, energy, automotive, and transportation

Sanmina serves industrial energy systems, electric vehicle programs, and advanced driver-assistance systems. Management has noted some short-term automotive softness, so this is not the main growth driver right now.

Option

Data center cooling and power hardware

Sanmina is targeting liquid cooling rack systems, bus bars, and expanded full system integration and test capability. These investments aim to match the higher power and cooling needs of AI servers.

The mix below uses Q2 FY26 end-market revenue from Sanmina’s Form 10-Q: $2.77 billion from Communication Networks and Cloud and AI Infrastructure, and $1.24 billion from the other grouped markets. Cloud and AI reached 69% of revenue, up from 62% in Q1 FY26, which raises customer concentration risk.

05 Risk factors

What could break the thesis

ZT integration misses the plan

High impact · Medium odds

ZT Systems is now central to Sanmina’s growth target. If Sanmina cannot manage the larger scale, hit quality targets, or get expected cost and revenue benefits, the FY27 revenue goal becomes harder to trust.

We watchListen for specific ZT synergy targets, margin progress, and whether management keeps the $16 billion plus FY27 revenue goal.

AI orders arrive in lumps

High impact · High odds

Q2 FY26 benefited from accelerated compute shipments that had been expected in the second half. That proves Sanmina can execute, but it also means quarterly revenue can jump around. A strong quarter may borrow demand from a later quarter.

We watchCompare Q3 FY26 results with guidance of $3.2 billion to $3.5 billion of revenue and $2.55 to $2.85 of non-GAAP EPS.

Cloud customer concentration

High impact · Medium odds

Cloud and AI infrastructure made up 69% of Q2 FY26 revenue. That makes Sanmina more dependent on a small number of large cloud service providers and data center operators. If one large buyer slows orders, revenue and profit could fall fast.

We watchWatch the end-market mix, any customer concentration language in filings, and signs that ZT wins new hyperscale or OEM customers.

Next-generation platform delays

High impact · Medium odds

Management’s FY27 confidence depends on new accelerated compute platforms ramping in late calendar 2026. If customer designs change, parts are late, or testing takes longer than expected, shipments can slip.

We watchTrack management comments on late calendar 2026 platform ramps and whether FY27 project timing stays on schedule.

Tariffs, geopolitics, and weaker end markets

Medium impact · Medium odds

Sanmina runs a global manufacturing network, so tariffs and geopolitical issues can raise costs or change customer plans. Management also noted some short-term softness in automotive, which can offset strength in other markets.

We watchWatch tariff commentary, customer location changes, and the Industrial, Medical, Defense, Aerospace and Automotive revenue trend.
