Core Sanmina revenue grew 17.0% year-over-year to $2.4 billion, exceeding internal expectations, while ZT Systems contributed $1.1 billion at the midpoint of outlook. Management attributed the performance to "Strong Execution, Mix and Disciplined Cost Management."
Year-Over-Year Financial Performance
The company’s year-over-year comparison revealed substantial improvements across all major financial metrics, driven by both organic growth and the ZT Systems acquisition.
Revenue increased from $2.042 billion in Q3 fiscal 2025 to $3.464 billion in Q3 fiscal 2026.

This diversification provides stability while capitalizing on AI-driven demand.
ZT Systems Integration Progress
Management provided a detailed update on the phased integration of ZT Systems, emphasizing execution against plan.
The company has completed the initial integration of ZT Systems and made capital investments in power, liquid cooling, and test cell capacity. Sanmina has won and shipped current-generation accelerated compute business while securing new, next-generation business with key hyperscale and OEM customers. The integration has already delivered initial vertical integration synergies for the core Sanmina business.
Actions in progress include additional investments in automation, expanding the customer base for next-generation accelerated compute business, and building pre-production units while finalizing customer production schedules. Future actions focus on continued investment, further customer base expansion, and driving additional vertical integration synergies.
Balance Sheet and Financial Position
Sanmina’s balance sheet reflects substantial liquidity and conservative leverage, positioning the company for continued growth investments.
As of June 27, 2026, the company held total assets of $9.740 billion, including $1.845 billion in cash and cash equivalents. Total stockholders’ equity stood at $2.760 billion. The company maintained substantial liquidity of $4.0 billion with no borrowings under its $1.5 billion revolver at quarter end. The net leverage ratio of 0.29x and non-GAAP pre-tax return on invested capital of 39.1% demonstrated strong financial health and capital efficiency.
The company’s cash flow profile reflected the investment phase of its growth strategy.
Cash flow from operations totaled $124 million, while net capital expenditures of $101 million supported capacity expansion, resulting in free cash flow of $24 million. Non-GAAP EBITDA reached $322 million. Management emphasized the theme of "Making Investments to Drive Growth," acknowledging that working capital requirements would increase as AI-related programs ramp.
Forward Guidance and Strategic Outlook
Sanmina provided guidance for the fourth quarter of fiscal 2026 and the full year, while expressing confidence in substantial growth for fiscal 2027.
For Q4 fiscal 2026, the company expects revenue of $3.3 billion to $3.6 billion, with core Sanmina revenue of $2.5 billion to $2.6 billion and ZT Systems revenue of $0.8 billion to $1.0 billion. The lower ZT Systems guidance reflects timing shifts in legacy programs, with next-generation accelerated compute revenue expected to begin contributing in fiscal 2027. Non-GAAP operating margin is projected at 7.5% to 8.0%, with diluted EPS of $3.05 to $3.35.
The full-year fiscal 2026 outlook demonstrates substantial growth momentum.
Management guided to full-year revenue of $14.0 billion to $14.3 billion, representing significant growth from prior years. Core Sanmina revenue is expected to reach $9.1 billion to $9.2 billion, with the midpoint representing 12.6% year-over-year growth. ZT Systems revenue of $4.8 billion to $5.0 billion for eleven months falls within the $5 billion to $6 billion annualized run rate. Non-GAAP operating margin is projected at 6.85% to 7.25%, with diluted EPS of $11.90 to $12.20.
Notably, the company stated it is "Confident in Our Ability to Deliver $16B+ in FY’27," signaling expectations for continued strong growth as AI infrastructure investments accelerate.

The presentation concluded with confidence that Sanmina is "Well Positioned for Strong Growth in FY’27 and FY’28."
Analyst Perspectives and Market Reaction
Despite the strong results, the market’s muted reaction reflected concerns about near-term dynamics and margin sustainability. During the earnings call, analysts pressed management on whether the 8.0% operating margin could hold as ZT-related AI revenue becomes a larger part of the mix. CFO Jon Faust acknowledged that the quarter benefited from favorable mix and higher-than-expected non-recurring engineering services, but maintained expectations for long-term margins in the 6% to 7% range.
Questions also focused on the pace of ZT Systems growth in fiscal 2027, with management noting that legacy accelerated compute platforms are essentially gone while next-generation programs remain on track but early stage. The company expects working capital pressure as inventory and receivables rise to support growth programs, which could weigh on cash flow in the near term.
The stock’s after-hours decline to $206.63 from the regular session close of $208.90 suggests investors are balancing the strong Q3 performance against execution risks and the timing of next-generation AI platform revenue. With shares trading in the upper half of the 52-week range of $97.77 to $288.68, the market appears to be pricing in substantial growth expectations while remaining cautious about near-term working capital dynamics and the integration of ZT Systems.
