Lenovo and Dell's AI-Powered Earnings Confirm Hardware Supercycle

AI revenue becomes the main engine

The metric markets seized on most was the AI revenue line. In Q4, AI-related sales grew 84% year-over-year, accounting for 38% of total group revenue . For the full fiscal year, AI-related revenue surged 105% and now represents 33% of total revenue, up from roughly 16% the prior year . This acceleration made AI the group's leading growth engine—a transformation that few investors had priced in before the report .

Infrastructure unit turns a critical corner

Perhaps more significant for the investment thesis was the performance of Lenovo's Infrastructure Solutions Group (ISG), which houses its server and data center business. ISG posted record quarterly revenue of $5.6 billion, up 37% year-over-year, and achieved profitability for the first time with an operating profit of $202 million . The division's AI server order pipeline reached $21 billion, supported by over 5,800 customer AI deployments and the shipment of the first GB300 NVL72 racks . CEO Yuanqing Yang set a new target of making Lenovo a $100 billion company, and multiple analysts raised price targets accordingly .

Dell's blowout: the same thesis on a much larger canvas

If Lenovo's report lit the fuse, Dell's Q1 FY2027 results on May 28 were the detonation. The numbers were so far above expectations that they recast what investors thought was possible for an enterprise hardware company in the middle of an AI capex cycle.

Dell posted record quarterly revenue of $43.8 billion, up 88% year-over-year and more than $8 billion above the consensus estimate of roughly $35.8 billion . Non-GAAP diluted earnings per share came in at $4.86, beating the $2.96 consensus by 64% and rising 214% from the prior year . On a GAAP basis, diluted EPS of $5.24 was up 282% year-over-year . The company also generated a record $4.1 billion in cash flow from operations .

AI server revenue scales to a new order of magnitude

The center of the beat was Dell's Infrastructure Solutions Group (ISG), which saw total revenue reach $29 billion, up 181% year-over-year . Inside ISG, AI-optimized server revenue hit $16.1 billion in the quarter—an increase of 757% over the previous year . The company booked $24.4 billion in new AI orders during those three months alone and ended the quarter with a total AI server backlog of $51.3 billion, up from roughly $43 billion the previous quarter . Dell's COO, Jeff Clarke, stated plainly that the AI opportunity "shows no signs of slowing" .

The company subsequently raised its full-year FY27 AI server revenue expectation to approximately $60 billion, lifting its overall revenue guidance to a midpoint of $167 billion .

What the combined results say about the AI hardware cycle

The back-to-back Lenovo and Dell reports provide unusually strong, multi-vendor evidence that the AI infrastructure buildout is in a sustained growth phase rather than a temporary spike. Four themes stand out.

1. Demand is accelerating, not peaking

Both companies reported the largest backlogs in their histories. Lenovo's $21 billion AI server pipeline and Dell's $51.3 billion backlog point to hyperscalers and large enterprises still in the early stages of AI infrastructure deployment . Orders are significantly outpacing shipments, and supply constraints remain the primary bottleneck—hardly a sign that the cycle is at its peak .

2. AI is shifting from a cost center to a profit driver

A major concern earlier in the cycle—that AI servers carry thin margins—is being put to rest. Lenovo's ISG turned profitable for the first time, and Dell's non-GAAP EPS more than tripled year-over-year . As deployment scale grows and supply chains mature, the economics of AI hardware are inflecting positively. Operating margins are expanding rather than contracting, signaling the profit inflection point investors had been waiting for .

3. AI is becoming the dominant revenue stream

At Lenovo, AI-related sales went from a modest contributor to 38% of quarterly revenue in a single year . At Dell, the Infrastructure Solutions Group—overwhelmingly driven by AI server demand—now accounts for roughly two-thirds of total revenue . These are not niche business lines anymore; for both companies, AI is rapidly becoming the core of the enterprise.

4. The cycle is broad-based, not just a hyperscaler phenomenon

Lenovo saw strong PC and smartphone demand alongside the AI server boom, in part driven by enterprise refresh cycles ahead of potential tariff-related price increases . This indicates that the infrastructure investment cycle is being reinforced by broader IT spending trends, rather than being a standalone silo of hyperscaler capex. Dell's Client Solutions Group also grew 17% to $14.6 billion, underscoring that enterprise demand is complementing the cloud provider buildout .

Bottom line: The Lenovo and Dell reports, taken together, deliver a powerful reality check for any argument that AI investment is a short-term bubble. Both hardware giants are operating at record scale, with order books swelling, margins improving, and management raising guidance across the board. For investors, the evidence points squarely toward a multi-year capital expenditure cycle that has yet to reach its midpoint.
