The mix, not the boom

Hewlett Packard Enterprise sells servers, storage and high-performance computing to enterprises, and — since closing its $14bn all-cash purchase of Juniper Networks — one of the largest enterprise networking franchises in the industry. In its quarter to April it converted $10.7bn of revenue into gross profit at a rate of 36.5 cents on the dollar, against 27.6 cents a year earlier. Revenue grew 41%. Gross profit grew 86%.

The reason is largely what HPE is not selling. AI systems orders were $1.8bn in the quarter, a rounding error beside Dell's book. Networking revenue was $2.7bn at a 13.3% operating margin, and management raised full-year networking growth guidance to 72-75%, lifted non-GAAP earnings guidance to $3.35-$3.45 a share, and guided to at least $3.5bn of free cash flow. Free cash flow in the quarter was a record $915m. The company said Juniper integration is running ahead of plan and that it sees no sign customers are pulling AI orders forward.

Dell is the AI-server business, and pays for it

Dell Technologies, the Round Rock, Texas group run by Michael Dell that sells servers and storage to enterprises and PCs to everyone else, is the volume leader in branded AI servers with roughly a fifth of the market. Its April-quarter revenue reached $43.8bn, up 87.5%. AI-optimized server revenue was $16.1bn, up 757%; Dell booked $24.4bn of AI orders and closed the quarter with $51.3bn of backlog, lifting full-year guidance by about $27bn.

Gross margin fell to 17.75% from 21.11%. The named mechanism is memory. Server DRAM contract prices rose 90-95% quarter on quarter in the first quarter of 2026 and a further 58-63% in the second, with NAND up 70-75%, because the three memory makers diverted capacity to high-bandwidth memory for AI accelerators. Dell raised list prices about 17% across its line on 30 March, after Lenovo reissued quotes 10-15% higher on New Year's Day. The squeeze is easing rather than ending: TrendForce expects server DRAM up 13-18% in the third quarter, partly because US cloud providers have signed multi-year agreements capping supplier increases.

Below the gross line Dell held together. Infrastructure Solutions operating margin rose 80 basis points to 10.5% even as AI servers grew nearly eightfold, and group operating income nearly tripled to $3.66bn. What did not happen is the attach story: storage revenue was $4.33bn, up only 8%, far slower than the racks it is supposed to ride alongside. The PC business, at $14.61bn and up 17%, is a passenger, not the driver.

What the share price has already paid

Dell's shares closed at $122.27 on 20 February and $434.78 on 20 August. Trailing gross profit over the same stretch grew roughly 19%, to $25.6bn. The price per dollar of trailing gross profit therefore went from about 3.9x in February to 7.0x in May to 11.4x now — four fifths of the move was re-rating. Consensus has run past the company: analysts model $173.1bn of revenue and $18.80 of earnings per share this fiscal year, against the $138-142bn Dell itself guided in May. On those estimates the shares are 23.3x forward earnings versus 34.3x trailing.

HPE's advance is smaller and better funded by its own numbers. The shares roughly doubled since February; the multiple of trailing gross profit went from about 2.9x to 5.5x while gross profit itself grew 30%, to $12.8bn. HPE trades at 15.6x forward earnings against 49.0x trailing, on a 5.6% trailing free-cash-flow yield. The debt is the offset: gross borrowings above $18bn after the Juniper deal, including $1.35bn of 7.625% mandatory convertible preferred, and a 2.0x net-debt-to-EBITDA target management is not expected to reach by 2027.

The two controls

Celestica, the Toronto contract manufacturer that designs and builds full AI racks, switches and storage for hyperscalers, is the test of whether cloud buyers are bypassing the brands. It is not losing: second-quarter revenue was $4.70bn, up 62%, full-year guidance went to $20.5bn, and OpenAI custom racks and AMD's Helios platform were named as multi-billion-dollar 2027 programs. Yet its multiple of trailing gross profit compressed from 26.3x in May to 18.9x, because on 5 August it sold 9.68m shares at $310, 14.5% below the prior close, raising about $3bn for capex and working capital. Its trailing free-cash-flow yield is 1.52%; its top three customers are roughly 65% of revenue. The de-rating is the cost of funding growth, not lost share.

Super Micro is the sharper control. The San Jose builder of high-density GPU systems — the whitebox alternative to a branded rack — reported June-quarter gross margin of 17.5%, up from 9.9%, on $11.1bn of revenue. That is now within a rounding error of Dell's 17.75%. Super Micro trades at 6.1x trailing gross profit and 10.9x trailing earnings, and its shares are up 12.6% over six months and down 14.3% over twelve. The branded socket and the unbranded one earn the same gross margin; only one of them carries an 11.4x multiple.

The bear case is not absent. At Barron's midyear roundtable, Scott Black judged Dell's hyperscaler servers to beat HPE's hands down on total cost of ownership and ease of maintenance — HPE's structural disadvantage in the very business Dell dominates. David Giroux has argued the opposite risk for both: hyperscaler in-sourcing plus rising memory costs squeezes every server OEM. What the April quarters showed is that those pressures land on the gross line of whoever ships the most accelerators, and that is Dell.

The setup

Where it stands — HPE's margin is expanding on networking mix while Dell's contracts on AI-server mix, and Dell's gross-profit multiple is twice HPE's.

Would confirm — HPE's next quarter holding networking operating margin in the low teens with full-year free cash flow tracking above $3.5bn.

Would invalidate — HPE gross margin falling back toward 30% as AI systems grow into a larger share of shipments.

Watch next — Dell reports second-quarter results on 1 September; HPE's fiscal third quarter follows in early September.

Valuation — HPE at 5.5x trailing gross profit and 4.8x forward, against Dell's 11.4x, Celestica's 18.9x and Super Micro's 6.1x.
