Sanmina is no longer only a diversified electronics manufacturer selling boards and boxes into industrial, medical, and defense programs. The October purchase of ZT Systems data-center manufacturing from Advanced Micro Devices recasts the San Jose company as a United States-based builder of rack-scale cloud hardware, with a preferred new-product-introduction role inside the AMD hyperscale channel. Core Sanmina still grew in the high teens during the fiscal third quarter, which means the old book of business is not standing still while the new one is bolted on. The investment debate is whether that combination is a durable earnings-power reset or a cycle purchase that concentrates customers, soaks cash in inventory, and leaves a sequential hole until next-generation racks start to recognize.
The third-quarter print argued both sides at once. Revenue of $3.46 billion sat at the high end of the company's own range. Non-GAAP operating margin reached eight percent, a level the pre-deal franchise rarely held. That margin lift is the constructive case: mix, cost control, and engineering around product launches converted a hardware-heavy quarter into earnings power that outran the sales line. The skeptical case lives in cash and concentration. Operating cash flow of $124 million barely covered plant spending. Capital outlays ran about $101 million, and free cash flow compressed to $24 million. Inventory, even after netting customer advances, remains swollen because ZT and the core franchise are building ahead of the next compute cycle.
Management raised full-year revenue, margin, and earnings guidance after the quarter and still points to more than $16 billion of fiscal 2027 sales as next-generation accelerated-compute programs ramp. The fourth-quarter outlook, however, holds revenue roughly flat and trims the ZT contribution on leftover-program timing, not on those next-generation racks. Shares closed near $200 on the publication date, a little more than fourteen times forward earnings after a retreat from the yearly high. The next several quarters resolve whether margin stays near the new high-water mark while cash conversion catches the income statement, or whether the ZT air pocket and working-capital soak prove that the multiple already paid for a cycle that has not yet converted.
