Sanmina’s customer dynamics: how AMD ramps as Nvidia recedes and what investors should price in

Sanmina Corporation operates as a global contract manufacturer and integrated solutions provider to OEMs across industrial, medical, defense, automotive, communications networks and cloud infrastructure. The company monetizes through manufacturing contracts, component sourcing, logistics and after‑sales services, generating roughly $9.3 billion in trailing revenue while concentrating risk: Sanmina’s ten largest customers accounted for 52% of net sales in 2025. Investors should value Sanmina as a manufacturing platform whose near‑term revenue trajectory is driven by the cadence of large cloud and accelerated‑compute rack programs and the mix between multi‑year supply agreements and short-cycle performance obligations.

Recent headlines: what the market is asking about Sanmina’s customer pivot

Analysts and reporters focused Sanmina’s latest commentary squarely on compute racks and the vendor mix behind them. The market’s central question is how quickly Sanmina — including its ZT Systems business — can replace declining NVIDIA rack volumes with AMD‑based rack builds, and what that timing implies for revenue and margin in FY2026.

  • According to an Intellectia summary of Sanmina’s FY2026 call materials, client questions directly raised the speed of revenue transition from NVIDIA to AMD rack projects. The piece ran in March 2026 and framed the swap as the primary near‑term growth driver.
  • The Globe and Mail’s coverage of Sanmina’s Q4 call in March 2026 recorded management remarks that legacy platforms have rolled off and that AMD‑driven accelerated compute projects are expected to ramp toward the end of FY2026.
  • A March 2026 summary on Finviz emphasized new projects and partnerships—particularly with AMD—anticipated to drive results in the second half of the fiscal year and beyond.

Together these reports establish a clear, investor‑relevant narrative: Sanmina is in the midst of a compute‑vendor transition that will determine near‑term revenue growth.

Customer relationship snapshots (every relationship in the coverage)

Below are concise, source‑backed summaries of the customer relationships referenced in recent reporting.

AMD

Sanmina is positioning for an AMD‑led ramp in accelerated compute rack projects, with management and analysts expecting AMD‑driven programs to ramp toward the second half of FY2026. This dynamic was discussed on Sanmina’s Q4 earnings call and summarized in March 2026 coverage by The Globe and Mail as well as in analyst Q&A reported via Intellectia. (Sources: The Globe and Mail, March 2026; Intellectia, March 2026).

NVIDIA

Sanmina acknowledged a decline in revenues from NVIDIA rack builds and fielded direct questions about the pace of transition away from NVIDIA to AMD platforms during Q4/FY2026 commentary. Intellectia’s March 2026 reporting captured the market’s focus on how quickly Sanmina/ZT Systems can compensate for the NVIDIA decline with AMD projects. (Sources: Intellectia, March 2026; The Globe and Mail, March 2026).

How these customer moves map to Sanmina’s operating model and constraints

Sanmina’s disclosed operating characteristics explain why the AMD/NVIDIA transition matters so much to investors:

  • Contracting posture: Sanmina runs a hybrid contracting model. The company reports entering supply agreements with major OEM customers that span three to five years, providing multi‑year visibility for certain programs, while many performance obligations are short‑duration (one year or less) and therefore sensitive to rapid demand shifts. This mix creates both baseline stability from long contracts and cyclical exposure from short‑term orders.
  • Concentration and materiality: Sales to Sanmina’s ten largest customers represented 52% of net sales in 2025, a company‑level signal that customer wins or losses have outsized P&L impact. This concentration elevates the strategic importance of large cloud/AI programs.
  • Global footprint and criticality: Sanmina positions itself as a global provider able to deliver regional manufacturing when time‑to‑market or local content rules are critical; this is exactly the capability cloud and AI OEMs require for rack deployments.
  • Role and segment: Sanmina is the seller—the contract manufacturer—operating a single IMS reportable segment that accounted for roughly 80% of revenue in 2025, underscoring the company’s dependence on volume manufacturing economics.
  • Relationship maturity: Management frames its approach as building long‑term partnerships, but the business also demonstrates active, short‑cycle relationships tied to program rollouts; investors should expect a mix of mature strategic programs and active operational engagements.

These constraints explain the sensitivity of margins and free cash flow to program timing: long‑term contracts underpin baseline capacity utilization, while short obligations and high customer concentration cause headline volatility when a major rack program accelerates or decelerates.

Investment implications and risks

  • Growth conditional on execution: The market should assign a premium only if Sanmina converts AMD pipeline into production volumes at pace sufficient to offset NVIDIA declines; if the AMD ramp slips, top‑line and operating leverage will be adversely affected given customer concentration.
  • Margin variability: Program mix (custom racks vs. component manufacturing, regional footprint) will determine gross margins; long‑term supply agreements can stabilize margins, but short‑term work magnifies swings.
  • Operational leverage and capital allocation: ZT Systems’ rack business is a critical lever; successful scaling of AMD racks will improve utilization across the manufacturing footprint, while delays will pressure capacity economics.
  • Monitoring checklist: Watch quarterly disclosures for revenue by program or customer, commentary on ZT Systems build rates, book‑to‑bill trends, and any updates to the composition of the top ten customers.

Final takeaways and action items

Sanmina’s FY2026 story is a classic industrial‑technology pivot: a large, global contract manufacturer reconciling a decline from one key compute vendor with an expected ramp from another. Given that the top ten customers represented 52% of sales in 2025 and IMS drives roughly 80% of revenue, the AMD/NVIDIA mix is not peripheral — it is central to near‑term valuation.

  • Key claim: The speed of the AMD rack ramp will determine FY2026 revenue trajectory and near‑term margin recovery.
  • Key risk: Customer concentration and short‑cycle obligations create pronounced volatility if major programs slip.
