StockStory’s Take

Sanmina's fourth quarter was marked by strong top-line growth, with revenue ahead of Wall Street's expectations and significant momentum in communications networks and cloud infrastructure. Despite these positives, the market reacted negatively as investors weighed the company's softer operating margin and the challenges of integrating the recently acquired ZT Systems. CEO Jure Sola attributed revenue strength to robust demand for high-performance network systems and initial shipments of next-generation AI infrastructure products, while acknowledging that certain segments like automotive and transportation remained stable but had yet to return to growth.

Looking ahead, Sanmina’s outlook is shaped by ongoing investments in AI data center capabilities and expectations for new platform launches later in the year. Management pointed to a strong pipeline of projects in both legacy and acquired businesses, with the ZT Systems acquisition expected to drive much of the revenue growth. Sola emphasized a focus on higher-margin opportunities and vertical integration, stating, “We are positioning the company to push for higher-margin business, something that is sustainable, not just for one quarter, but for many quarters.”

Key Insights from Management’s Remarks

Management cited robust demand for advanced networking and AI infrastructure, as well as operational efficiencies and diversification across end markets, as the primary drivers behind the quarter’s performance.

• AI and cloud infrastructure strength: Sanmina saw sustained demand in high-density networking, enterprise storage, and began shipments of 1.6 terabyte systems, with AI and cloud end markets accounting for a significant portion of growth.
• ZT Systems integration progress: The ZT Systems acquisition contributed to revenue expansion in the quarter, with integration proceeding on schedule and management highlighting immediate accretion to earnings per share.
• Operational discipline: The company maintained strong cash flow and improved working capital management, investing heavily in new capacity and technology in the U.S., India, and Mexico to support future growth.
• End market diversification: While communications and cloud segments led growth, industrial, energy, medical, defense, and transportation collectively provided a stable revenue base, with new projects in industrial power and medical devices expected to ramp up in the coming quarters.
• Margin focus amid investments: Management noted short-term margin pressure in certain segments due to upfront investments in new programs, but expressed confidence that these will be margin accretive as they scale, especially with continued progress in vertical integration and advanced manufacturing.

Drivers of Future Performance

Sanmina’s forward outlook is driven by anticipated demand for AI and cloud infrastructure, ongoing investments in capacity, and a strategic focus on higher-margin opportunities.

• AI data center expansion: Management expects substantial growth in AI and cloud infrastructure, with new projects and partnerships—particularly with AMD—anticipated to drive results in the second half of the year and beyond. Investments in vertical integration are aimed at supporting large-scale data center deployments and improving profitability over time.
• Margin improvement initiatives: The company is prioritizing operational efficiencies and mix optimization, seeking to expand non-GAAP operating margins by shifting toward higher-value, technology-driven business lines. Management indicated that recent investments should result in sustainable margin gains as new programs ramp.
• End market recovery and stability: While automotive and transportation segments are stabilizing, Sanmina anticipates sequential growth in industrial and medical segments, with energy projects in Houston and new medical device launches expected to contribute meaningfully in the back half of the year.
