4 SEP 2026 — Dell's AI server backlog has outgrown the AI revenue it expects to book all year. In the second quarter it reported record revenue of $47 billion, up 58 per cent, booked $60.9 billion of AI server orders and ended with a $95 billion backlog. It recognised $16.4 billion of AI server revenue in the same three months, and full-year guidance for that line sits at $74 billion. The backlog is larger than the year.
What the quarter contained
Infrastructure Solutions Group revenue was $31.8 billion, up 89 per cent. Within it, traditional server and networking reached $10.5 billion, up 122 per cent, and storage $4.9 billion, up 26 per cent. Client Solutions Group, the personal computer business, was $15 billion, up 20 per cent.
Operating expenses fell 250 basis points to 8.5 per cent of revenue. Dell returned $4.3 billion through dividends and buybacks. Full-year revenue guidance was raised to $192 billion at the midpoint, and the AI server line was raised by $14 billion to $74 billion.
Interim chief financial officer David Kennedy summarised it as "earnings grew significantly faster than revenue, and that gap is the story of the quarter".
Two earnings-growth figures are circulating, and both are right
Coverage of this quarter reports earnings per share up 273 per cent in some places and up 203 per cent in others. Neither is a mistake.
Diluted earnings per share on a GAAP basis were $6.34, up 273 per cent. Non-GAAP diluted earnings per share were $7.04, up 203 per cent. The GAAP figure grew faster from a lower base because the prior-year quarter carried charges that the adjusted figure had already excluded.
Anyone comparing this quarter against another company's should check which measure they have in hand. A 70-percentage-point difference between two correct descriptions of the same result is the kind of thing that survives into a spreadsheet unlabelled.
Orders are not revenue, and the gap is now enormous
The $95 billion backlog moved the stock, and it is the figure that most needs care in interpretation. A backlog is work booked and not yet delivered, so it says a customer has committed and says nothing about when Dell can ship.
Set against capacity, Dell recognised $16.4 billion of AI server revenue this quarter and guides to $74 billion for the year. At that guided run rate, today's backlog represents more than fifteen months of shipments before a single further order is taken.
Orders of $60.9 billion in one quarter against $16.4 billion recognised means the queue grew by roughly $44 billion in three months. A backlog growing three times faster than it is being worked down contains a demand signal and a delivery problem in the same number. Only the demand signal is good news.
The constraint is upstream and it is not Dell's
Nothing in a server assembler's own factory explains a gap that size. Dell integrates accelerators, memory and networking that other companies make, so the pace at which the backlog converts is set by allocation of those components rather than by anything on Dell's line.
A booked order that cannot ship for a year is exposed to everything that can happen in a year. A customer's financing can change. A newer accelerator generation can make the ordered configuration undesirable. A data centre that was supposed to be energised may not be.
We wrote this week about a 474-gigawatt interconnection queue against a grid that peaks at 91. The same question applies here from the other end of the supply chain. Some share of this backlog is destined for buildings whose power is not yet connected, and neither Dell nor anyone reading its results can say what that share is.
The margin question the growth rate hides
Assembling AI servers is a low-margin business. The value sits in the accelerators, which Dell buys, and the assembler captures a thin layer on top of a very large number.
The operating expense line is the more interesting disclosure. Dell took costs down to 8.5 per cent of revenue, a 250 basis point improvement. That, and not any improvement in what Dell earns per box, is what produced earnings growth ahead of revenue growth.
That kind of operating leverage works while revenue is climbing at 58 per cent and reverses as soon as it stops. A fixed cost base spread over a rising number flatters the ratio; the same base spread over a falling one does the opposite. The backlog does not protect against that, because a backlog can be cancelled.
What to look for in the next report
Three figures would settle the questions above, and Dell publishes two of them. One is whether the backlog keeps growing or begins converting; the healthy version would be a backlog that stops growing while revenue accelerates. Another is whether the full-year AI guidance of $74 billion is met, raised or trimmed. The third is whether operating expenses hold at 8.5 per cent once the comparison base gets harder.
The third figure is the one nobody discloses: cancellation and rescheduling within the backlog. Every large order book contains some, and in a business where the delivery window runs past a year and the underlying hardware generation turns over inside it, the amount is not small and not published.
