AMD announced on May 19, 2025 that it would sell ZT Systems’ U.S.-headquartered data-center infrastructure manufacturing business to Sanmina for up to $3 billion in cash and stock. The divestiture closed on October 27, 2025, with $2.4 billion in reported cash consideration, 1,151,052 Sanmina shares and potential additional payments of up to $450 million through 2028. AMD retained ZT’s rack-scale AI design and customer-enablement operations, so this was a partial divestiture—not a sale of all of ZT Systems or an exit from AI systems.
What AMD sold to Sanmina
The transaction covered ZT Systems’ U.S.-headquartered data-center infrastructure manufacturing business. That includes production operations and associated manufacturing assets, rather than every activity performed under the ZT Systems name. AMD’s filing says the manufacturing business represented the majority of ZT Systems’ operations and was classified as held for sale when AMD acquired the company. The business was subsequently reported as discontinued operations.
Sanmina Corporation (NASDAQ: SANM), an integrated manufacturing-solutions provider, became the buyer. AMD and Sanmina also entered a Manufacturing Services Agreement with an initial five-year term. Sanmina became a preferred new-product-introduction (NPI) manufacturing partner for AMD’s cloud-rack and cluster-scale AI systems. NPI work generally covers industrialization, validation and production ramp-up; it does not transfer ownership of AMD’s chip roadmap or all system-design responsibilities.
What AMD kept
| Transferred to Sanmina | Retained by AMD |
|---|---|
| ZT Systems’ U.S.-headquartered data-center infrastructure manufacturing operations | Rack-scale AI system design capabilities |
| Production activities and related manufacturing assets | Customer-enablement teams and deployment knowledge |
| Manufacturing workforce and operations within the divested perimeter | Selected intellectual property and employees tied to the design business |
AMD therefore did not sell its AI-systems business or abandon server infrastructure. Its retained design organization remains part of continuing operations in AMD’s Data Center segment, while the manufacturing operation moved to Sanmina.

How the $3 billion headline breaks down
AMD’s May 19 announcement described an aggregate transaction value of up to $3 billion in cash and stock, including up to $450 million of contingent consideration. That headline was not a promise of $3 billion in cash paid at closing.
| Component | Reported amount and qualification |
|---|---|
| Cash consideration | $2.4 billion, subject to purchase-price adjustments |
| Sanmina common stock | 1,151,052 shares |
| Value of Sanmina shares at closing | Approximately $154 million, based on the closing valuation reported by AMD |
| Net cash received by AMD | Approximately $1.4 billion after cash divested and purchase-price adjustments |
| Potential earn-out | Up to $450 million in additional cash through 2028, contingent on future conditions |
The announcement is documented in AMD’s May 19, 2025 release. AMD’s later SEC filing reports the closing economics and earn-out terms at this filing. The $1.4 billion net-cash figure is not interchangeable with the $2.4 billion contractual cash consideration: it reflects cash transferred with the business and other closing adjustments.

Timeline: acquisition, agreement and closing
- August 19, 2024: AMD announced an agreement to acquire ZT Systems for approximately $4.9 billion in cash and stock, while saying it intended to seek a buyer for the manufacturing business.
- March 31, 2025: AMD completed the ZT Systems acquisition. Its later filing reports approximately $4.409 billion of total purchase consideration for the broader company, including cash, AMD stock and contingent consideration.
- May 19, 2025: AMD announced the agreement to sell the manufacturing business to Sanmina for up to $3 billion in cash and stock, including contingent consideration.
- October 27, 2025: The divestiture closed, as reported in the companies’ transaction announcement at AMD’s investor-relations filing.
- March 28, 2026: AMD’s quarterly filing detailed the $2.4 billion cash consideration, Sanmina shares, net cash received, earn-out opportunity and five-year initial Manufacturing Services Agreement term.
The acquisition and divestiture values should not be compared as if they measured the same asset. AMD bought the broader ZT Systems company and sold only its manufacturing business.
Why AMD bought ZT Systems and then separated manufacturing
AMD announced the acquisition as a way to move beyond individual chips into complete AI infrastructure and accelerate deployment of AMD-powered systems for hyperscale customers. The retained capabilities give AMD direct expertise in system architecture, rack-scale design, validation and customer deployment requirements.
Rank #3
- Can deliver fast 100 plus FPS performance in the world's most popular games, discrete graphics card required
- 6 Cores and 12 processing threads, bundled with the AMD Wraith Stealth cooler
- 4.2 GHz Max Boost, unlocked for overclocking, 19 MB cache, DDR4-3200 support
- For the advanced Socket AM4 platform
At the same time, AMD’s original acquisition disclosure said it intended to find a buyer for the manufacturing business. Operating factories and production operations has different capital, utilization, supply-chain and margin requirements from designing processors, accelerators and software. The structure lets AMD retain system-level knowledge while using a specialized manufacturing partner rather than owning the entire production operation.
AMD has described faster deployment and closer integration among silicon, software and systems as strategic goals, not guaranteed financial outcomes. Its divestiture announcement identifies execution, customer, manufacturing-partner and transaction risks.

Why Sanmina agreed to the transaction
For Sanmina, the deal adds an established data-center infrastructure manufacturing platform and exposure to AI servers, rack-scale systems and hyperscale deployments. The preferred NPI relationship with AMD could provide a formal channel for industrializing new AMD-based systems.
Those are expected strategic benefits rather than guaranteed revenue, margin or customer-retention results. Sanmina must integrate the operation, manage working capital and component availability, and maintain delivery performance for a customer base that can be concentrated among a small number of large cloud providers. The transaction did not transfer AMD’s retained design and customer-enablement functions, so Sanmina acquired manufacturing scope—not the entirety of ZT Systems’ former activities.

What investors and enterprise buyers should watch
- Earn-out realization: Up to $450 million remains contingent through 2028 and should not be treated as cash already received.
- Manufacturing agreement performance: The five-year initial term creates an ongoing relationship, but it does not establish exclusivity, guaranteed capacity, pricing or customer adoption.
- AMD’s system execution: The retained design and enablement teams must translate their expertise into validated deployments and customer programs.
- Sanmina’s integration: Delivery continuity, factory utilization, component supply and margins will determine whether the acquired operation performs as intended.
- Customer concentration: AI infrastructure demand can depend heavily on a limited group of hyperscale customers, increasing execution and forecasting risk.
What the deal means for the AI-server market
The transaction illustrates a division of labor emerging in AI infrastructure. Chip companies increasingly want to supply validated systems and reference architectures, while hyperscalers need rack-level integration and rapid production ramps. Contract manufacturers and original-design manufacturers provide factories, supply-chain management and production scale.
AMD’s approach is to own more of the system architecture and customer-enablement layer without becoming a conventional, full-scale server manufacturer. That may reduce the capital and operational burden of manufacturing ownership while preserving influence over how its CPUs and accelerators are deployed. The deal itself does not prove that AMD has gained market share or achieved a particular return; those outcomes depend on execution after closing.
Bottom line
AMD did not sell all of ZT Systems for $3 billion in cash. It agreed on May 19, 2025 to sell the manufacturing business to Sanmina, completed that sale on October 27, 2025, and retained ZT’s AI-system design and customer-enablement operations. The final reported consideration was $2.4 billion in cash plus Sanmina stock, with up to $450 million of additional contingent payments through 2028. Sanmina now owns the manufacturing operation, while AMD continues to participate in system design and production through its ongoing manufacturing relationship.
