Super Micro Computer, Inc. (SMCI) | The Buildout — AI Infrastructure

The Verdict

Supermicro builds the machines that go inside AI data centers. It buys GPUs and CPUs from chipmakers, integrates them into dense rack-scale systems, and sells the racks to cloud service providers, large data centers and enterprises. Under its DCBBS banner it is bundling more of the surrounding data center: liquid cooling, networking, data-center management software and lifecycle services. The company positions this integration, and the speed at which a customer can get a rack running, as its value. It sits one layer below the silicon — it does not design the processors its systems depend on — and it competes with server vendors and contract manufacturers that assemble similar machines.

Earnings

Q4 FY26 revenue was $11.1B, up 93% year over year and 9% quarter over quarter, landing near the low end of the $11.0B–$12.5B guide because customer site readiness delayed shipments. Gross margin was 17.5%, far above the guided 8.2%–8.4%, on favorable mix. The quarter's standout was the order book: management disclosed record new orders.

Management tone: Management was expansive on demand and strategy, and guarded on the two topics the skeptics press on. The Q4 call opened with the record order disclosure and a step-change FY27 guide, and spent little of the prepared remarks on the revenue miss. On the Q1 FY27 gross-margin reset, the disclosure was direct. Asked for a full-year FY27 margin framework, management pointed to the Q1 range rather than giving one. Asked for a Board investigation update, it said it expects to provide one shortly.

Management Guidance

For Q1 FY27, management guided net sales of $14.5B–$15.5B, gross margin of 10.4%–10.8% ("Based on the expected customer and product mix"), GAAP diluted EPS of $0.89–$0.98 and non-GAAP diluted EPS of $1.01–$1.10. It guided GAAP opex to about $453M including roughly $127M of stock-based compensation, other income/expense to a net expense of about $45M, tax to 20.1% GAAP and 20.5% non-GAAP, and CapEx to $50M–$60M. For the full year FY27, it guided net sales of $65B–$72B. It also said it has no plans to use its ATM program, that AI-related revenue should be greater than 80% going forward, and that it expects the cash conversion cycle to normalize based on terms in the current backlog.

Trajectory

FY26 revenue was $39.1B, up 78% from about $22B in FY25, and the revenue direction is accelerating. Q4 revenue of $11.1B rose 93% year over year but only 9% sequentially, because customer readiness delays pushed shipments out. Gross margin has been volatile: 6.3% in Q2 FY26, 9.9% in Q3 and 17.5% in Q4, with Q1 FY27 guided back to 10.4%–10.8%. For the full year, non-GAAP gross margin was 10.9% versus 11.2% in FY25 — the annual margin compressed even as the Q4 exit rate spiked. Operating and EBITDA margins are expanding. The weak spot is cash: FY26 operating cash flow was −$6.8B and the cash conversion cycle reached 149 days.

The Model

The model projects FY+1 revenue of $70,000M and EBITDA of $5,810M (8.3% margin), and FY+2 revenue of $88,000M and EBITDA of $7,920M (9.0% margin). Near term, the FY+1 revenue figure sits inside management's guided fiscal-2027 range of $65B–$72B, so it is anchored to the order book and the guided ramp. The FY+2 step-up assumes that order book converts and that the mix shift toward enterprise, DCBBS and software lifts the EBITDA margin toward 9.0%. Across the five model runs, FY+2 revenue spans $86,000M to $95,000M.

Projections are the median of 5 independent model runs. The model’s revenue sits 46.3% above analyst consensus.

For Q1 FY27, management guided net sales of $14.5B–$15.5B, gross margin of 10.4%–10.8% ("Based on the expected customer and product mix"), GAAP diluted EPS of $0.89–$0.98 and non-GAAP diluted EPS of $1.01–$1.10. It guided GAAP opex to about $453M including roughly $127M of stock-based compensation, other income/expense to a net expense of about $45M, tax to 20.1% GAAP and 20.5% non-GAAP, and CapEx to $50M–$60M. For the full year FY27, it guided net sales of $65B–$72B. It also said it has no plans to use its ATM program, that AI-related revenue should be greater than 80% going forward, and that it expects the cash conversion cycle to normalize based on terms in the current backlog.

What Could Go Right — and Wrong

Looking Ahead

The next twelve months turn on one question: whether the record order book converts. Management guides FY27 revenue to a step-change from FY26. The Q1 FY27 report tests both the revenue ramp and the margin reset. On the product side, Supermicro says it is shipping NVIDIA GB300 NVL72 systems, preparing what it calls first-to-market Vera Rubin systems, and building out a 32-acre Silicon Valley campus that brings its total US footprint to nearly 4 million square feet. DCBBS remains unquantified. The legal overhang is not closed: the independent investigation was completed on 2026-08-20, and officer-and-director investigations were announced in late August and September 2026.

The Company

Supermicro builds the servers that go inside AI data centers. It buys GPUs from NVIDIA and AMD and CPUs from AMD and Intel, then integrates them into rack-scale systems — the GB300 NVL72, HGX B300 and similar high-density platforms — sold to cloud service providers, large data centers and enterprises. Under its DCBBS banner it is bundling more of the surrounding data center: direct liquid cooling, CDUs, chilled doors, water towers, high-speed networking, data-center management software and lifecycle services. Management describes the company as moving from a US-based server designer and manufacturer toward a total data center solution provider.

Supermicro designs and manufactures in the United States, Taiwan, Malaysia and the Netherlands, and it owns rather than leases nearly all of that manufacturing space. Its San Jose, California headquarters and production site is about 1,601,000 square feet and owned; it also owns roughly 954,000 square feet in Taoyuan, Taiwan and about 590,000 square feet in Malaysia on 30 acres, and leases about 350,000 square feet of office and manufacturing in Den Bosch, Netherlands. A new 32-acre Silicon Valley campus brings the total US footprint to nearly 4 million square feet. Two related-party suppliers, Ablecom and Compuware, manufactured about 94% of chassis and about 92% of power supplies purchased in the March 2026 quarter.

Business Segments

Competitive Landscape

The 10-K names global technology vendors Cisco, Dell, Hewlett-Packard Enterprise and Lenovo, and ODMs Foxconn, Quanta Computer and Wiwynn, as competitors. The competitive question the evidence raises is whether large data center and cloud customers buy through integrators like Supermicro or go directly to ODMs. Asked about that on the Q4 call, management focused on power and data-center readiness and liquid cooling and described the company as "both ODM and OEM, we will continue to grow in both ways" rather than directly rebutting the concern. The criticality assessment notes that multiple alternative server assemblers exist and switching would take months.

Supply Chain

Supermicro sits between chipmakers and data center operators. It buys GPUs, CPUs, memory, switching and cooling parts, then integrates them into racks. AMD named Supermicro by name as a fifth-generation EPYC platform partner; most other neighbors did not name it.
