Sanmina Stock Advances Amid AI Infrastructure Expansion and Strategic Partnerships
## Sanmina Shares Advance Following AI Infrastructure Focus
**Sanmina Corporation** (NASDAQ: SANM) shares advanced by 22.72% on October 6th, reflecting investor optimism regarding the company's strategic positioning within the rapidly expanding artificial intelligence (AI) infrastructure sector. The upward movement pushed **Sanmina's** stock to $140 per share, largely influenced by developments surrounding its **ZT Systems** acquisition and a significant strategic partnership between **Advanced Micro Devices (AMD)** and **OpenAI**.
## Detailing Key Strategic Alignments
The market's positive reaction stems from a confluence of events highlighting **Sanmina's** elevated role in the AI supply chain. Earlier this year, **AMD** entered into a major multiyear agreement with **OpenAI**, a deal projected to involve the deployment of up to six gigawatts of **AMD Instinct GPUs**. This collaboration, commencing with **MI450 GPUs** in the second half of 2026, has a potential sales value estimated at $90 billion USD over time. To align interests, **AMD** has also issued **OpenAI** warrants for up to 160 million **AMD** shares, contingent on performance milestones.
Crucially for **Sanmina**, **AMD** initially acquired **ZT Systems**, a provider of cloud and AI infrastructure. Subsequently, **AMD** divested **ZT Systems'** U.S.-headquartered data center infrastructure manufacturing business to **Sanmina** for up to $3 billion. This transaction established **Sanmina** as **AMD's** preferred New Product Introduction (NPI) manufacturing partner for its cloud rack and cluster-scale AI solutions. This arrangement positions **Sanmina's ZT Systems** to be a pivotal U.S.-based manufacturing hub for the significant **AMD**/**OpenAI** GPU deployments.
## Analysis of Market Drivers and Financial Performance
The catalyst for **Sanmina's** stock advance is the perceived direct link to the massive investments in AI infrastructure. By becoming a primary manufacturing partner for **AMD's** AI hardware, **Sanmina** is seen as a direct beneficiary of the burgeoning demand for high-performance computing necessary to power large-scale AI models. This strategic alignment transforms **Sanmina** from a traditional contract manufacturer into a high-value partner in next-generation computing infrastructure.
In addition to these strategic developments, **Sanmina** reported robust third-quarter fiscal 2025 financial results on July 28, 2025. The company's revenue reached $2.04 billion, marking a 10.9% increase year-over-year. Non-GAAP diluted earnings per share (EPS) stood at $1.53, surpassing consensus estimates by $0.11. **Sanmina** also demonstrated strong financial health with $201 million in cash flow from operations and $168 million in free cash flow for the quarter, ending with $798 million in cash and cash equivalents against $287 million in long-term debt.
## Broader Context and Future Implications
The acquisition of **ZT Systems** is projected to add $5 billion to $6 billion in annual net revenue, potentially doubling **Sanmina's** top line within three years and enhancing its exposure to the AI and data center markets. This move significantly elevates **Sanmina's** capabilities, allowing it to compete in the high-growth segments of AI hardware manufacturing. The broader market for AI infrastructure is experiencing unprecedented growth, with investments measured in gigawatts and hundreds of billions of dollars, reflecting a significant building boom driven by hyperscalers and AI developers seeking to diversify their supply chains beyond dominant players like **NVIDIA**.
Despite the strong operational performance and strategic growth prospects, valuation metrics for **Sanmina** warrant attention. The stock currently trades at a P/E ratio of 29.98 and a P/B ratio of 3.25. While the company exhibits strong financial strength with a Piotroski F-Score of 8, its GF Value suggests it is "Significantly Overvalued" at a current value of $69.07, highlighting a potential disconnect between market price and intrinsic value. The Altman Z-score of 2.9 indicates a presence in the grey area of financial stress.
## Expert Commentary
Analysts acknowledge the positive implications of these strategic moves. **Bank of America** analyst Ruplu Bhattacharya, following a meeting with **Sanmina's** CFO Jon Faust, noted management's confidence that **ZT Systems** could substantially increase annual net revenue and be accretive by approximately $1.00 per share in 2026. However, Bhattacharya also maintained a "Neutral" rating with a $130 price target, expressing caution regarding the broader macroeconomic backdrop and potential integration risks associated with the acquisition.
> "SANM will be AMD's preferred NPI partner," Bhattacharya stated, emphasizing that Sanmina will gain valuable experience helping AMD build, test, and prepare its GPU racks for production, which could translate into long-term manufacturing deals with other AI chip leaders like **NVIDIA**.
## Looking Ahead
The immediate focus for **Sanmina** will be the seamless integration of **ZT Systems'** manufacturing operations and the successful execution of its role as **AMD's** NPI partner. Investors will closely monitor the realization of projected revenue growth from the **ZT Systems** acquisition and the tangible impact of the **AMD**/**OpenAI** partnership on **Sanmina's** financial performance. The sustainability of massive AI infrastructure investments and the competitive landscape with **NVIDIA** will also be critical factors to watch in the coming quarters. While **Sanmina's** strategic pivot positions it for significant growth, navigating valuation concerns and operational integration will be key to long-term success.
