SANM
Sanmina Corporation
Summary
What they do:
Contract electronics manufacturer (EMS/ODM) that builds servers, networking equipment, optical assemblies, and complex electronics for OEMs and hyperscalers — sitting at the final assembly step where upstream chips, memory, power supplies, and cooling come together into a finished system. Acquired ZT Systems' data center manufacturing business from AMD in October 2025, roughly doubling revenue scale.
Why they matter:
The ZT Systems deal transformed Sanmina from a diversified EMS provider into the largest pure-play contract AI server manufacturer. With ~$5-6B in annualized ZT revenue focused on hyperscaler cloud and AI infrastructure, Sanmina now builds AI racks and cluster-scale systems for AMD and major cloud customers — a US-based manufacturing partner of choice as hyperscalers outsource complex assembly at unprecedented volumes.
Recent performance:
Q1 FY2026 revenue $3.19B, up 59% YoY. Non-GAAP EPS $2.38, beating consensus by ~10%. Full year FY2026 revenue tracking toward $14B+. Q2 FY2026 guidance: revenue $3.1-3.4B, non-GAAP EPS $2.25-$2.55. Stock ~$168, market cap ~$9.2B.
Our Verdict
Emerging server assembly play scaled up via ZT Systems acquisition — AI exposure jumped to 60%+ but contract manufacturing margins remain thin and integration risk is real at 16x forward earnings.

Sanmina is a contract electronics manufacturer — the company that builds things other companies design. For decades, this meant assembling networking equipment, medical devices, industrial systems, and telecom hardware across factories in the US, Mexico, and Asia. Sanmina's core skill is taking a customer's blueprints and turning them into finished products at scale, managing the supply chain, PCB fabrication, system integration, and testing. It is a high-volume, low-margin business where execution and cost discipline matter more than proprietary technology.
In October 2025, Sanmina completed the acquisition that reshaped the company: it bought ZT Systems' data center infrastructure manufacturing business from AMD for up to $3 billion ($2.55B in cash and equity, plus $450M in contingent consideration). ZT Systems was a hyperscaler-focused server and rack manufacturer generating $5-6 billion in annual revenue — primarily building cloud and AI infrastructure for the largest data center operators. AMD had acquired ZT Systems for its design capabilities but divested the manufacturing arm to Sanmina, retaining a strategic partnership where Sanmina serves as AMD's preferred US-based manufacturing partner for AI rack and cluster-scale solutions.
The impact was immediate. Q1 FY2026 revenue hit $3.19B — up 59% year-over-year — with ZT contributing roughly $850M-$1.05B in just two months of consolidation. The IMS (Integrated Manufacturing Solutions) segment surged 72% to $2.79B. Management guided full-year FY2026 revenue toward $14B+, more than doubling FY2025's $8.13B. Cloud and AI infrastructure now accounts for approximately 62% of revenue, up from roughly 15-20% pre-acquisition.
Sanmina operates across two segments: IMS ($2.79B in Q1, encompassing server assembly, networking, and systems integration) and CPS (Components, Products and Services — $448M in Q1, covering PCB fabrication, optical assemblies, and precision machining). The company runs manufacturing facilities in the US, Mexico, Malaysia, and China. Non-GAAP operating margin was 6.0% in Q1 FY2026, up 40bps year-over-year — thin by semiconductor standards, but typical for EMS and improving as ZT integration matures.

The Catch
Sanmina bet the company on ZT Systems. The $3 billion acquisition (including contingent consideration) nearly doubled revenue overnight but also loaded $2.5B in acquisition debt onto a business that earns 6% operating margins. If anything disrupts the integration — customer attrition, operational issues at ZT facilities, or a slowdown in AMD AI platform demand — Sanmina is left with significant debt and thin margins on a larger but less profitable business. The fundamental problem with contract manufacturing remains: Sanmina does not own the customer relationship in the way Dell or SMCI do. Hyperscalers can and do dual-source manufacturing. The AMD partnership provides a floor, but if AMD's AI market share erodes against NVIDIA, that floor lowers. And the broader EMS industry offers no shortage of competitors — Celestica, Flex, and the Asian ODMs (Foxconn, Quanta) will compete aggressively for every hyperscaler program. Sanmina's margins are thin because its moat is thin. The ZT deal does not change the structural economics of contract manufacturing; it just scales them up.
If They Win
If ZT integration delivers operating leverage, AMD's AI server platforms gain meaningful share against NVIDIA's ecosystem, and hyperscaler capex continues its multi-year acceleration, Sanmina becomes the manufacturing backbone of the AMD AI data center stack — a $16-18B revenue company earning 7-8% operating margins with a locked-in position as the preferred US-based builder of AI racks and cluster-scale systems. The AMD equity lock-up (3-year vesting) ensures alignment. Nearshoring demand gives Sanmina's US and Mexico facilities a structural advantage over Asian ODMs facing tariff and geopolitical risk. In this scenario, SANM re-rates from a contract manufacturer multiple (12-16x) to a strategic infrastructure partner multiple (18-22x) — not because the business fundamentally changes, but because the market recognizes that building AI infrastructure at hyperscale requires trusted, qualified, US-based manufacturing partners, and Sanmina is one of the few with the scale and relationships to do it.
