Hewlett Packard Enterprise spent the summer renaming itself. "We are leading with networking. We are at the core becoming a networking company," chief executive Antonio Neri told investors on the September 2 call, reporting the first full quarter with Juniper Networks consolidated into the results.

The quarter both supports the label and complicates it. HPE — which sells ProLiant servers, storage, Aruba campus wireless and GreenLake consumption contracts through resellers and integrators — posted revenue of $12.2bn, up about a third, with gross margin at 40.1% against 28.4% a year earlier and operating income up 182%. Networking revenue reached $2.9bn, up roughly 75%, at a 22.0% segment operating margin against 22.1% a year earlier. The growth was bought, not manufactured out of the deal's cost base.

One customer's budget

So, in a narrower sense, was the customer. On the same day as the results, HPE announced an expanded Oracle collaboration covering multi-year deployment of Juniper PTX and MX routers and QFX and EX switches across Oracle's AI data centers. It had already issued Oracle a warrant over 4,156,466 of its own shares at an exercise price of $0.01, vesting in tranches tied to Oracle's purchases and running to June 2029 — around $205m of equity handed over at a nominal strike.

That is worth the price because of what Oracle now spends. Its capital expenditure reached $55.7bn in fiscal 2026 against $21.2bn a year earlier, with roughly $70bn guided for fiscal 2027. Dell'Oro Group expects data-center switch sales into AI back-end networks to exceed $100bn by 2030. Arista, Cisco, HPE's Juniper and Nvidia are all bidding into the same pool, and increasingly into the same handful of buyers.

HPE's own AI networking line is running ahead of plan. "Cumulative networks for AI orders were $2.2 billion, surpassing our FY '26 target. As a result, we are increasing our year-end target to $2.5 billion to $3 billion," chief financial officer Marie Myers said on September 2. Total orders rose 42%, and unconditional purchase obligations — the working capital of funding backlog months ahead of shipment — stood at about $30.4bn at the end of July, from roughly $6bn. Net leverage was 1.8x, under the company's 2x target after the $1.4bn H3C sale, so the roughly $14bn Juniper purchase is not yet squeezing buybacks. Management guided fiscal 2027 to 13-17% revenue growth and earnings of $4.40 to $4.60 a share; consensus sits at the top of that range.

The same demand, priced three ways

Arista, which sells high-speed Ethernet switches running its own operating system to cloud and financial customers, is being paid very differently. Revenue grew 37.7% in the June quarter to $3.04bn, the fourth straight acceleration, and operating margin rose to 45.4% — yet gross margin fell 232 basis points to 62.9% as hyperscaler mix rose, with management saying offsetting pricing does not arrive until 2027. Deferred revenue was $6.9bn and multiyear purchase commitments tripled to $9.7bn. Microsoft and Meta were 26% and 16% of 2025 revenue. Meanwhile Nvidia took the number-one revenue position in data-center Ethernet switching in the March quarter, at 21.5% share against Arista's 20.7%, by bundling switches with accelerators. Chairperson and chief executive Jayshree Ullal was dismissive of the cheaper end of the threat on the August 4 call: "White box is certainly a tactical solution that we tend to see more in use cases that are simple, scale-up or scale-out where the actual amount of software and system requirements are low."

Cisco is the odd one out. Its revenue accelerated four quarters running to 17.6% growth in the July quarter, operating margin hit a record, and it booked $9.3bn of hyperscaler AI infrastructure orders in fiscal 2026 against $2bn the year before — though roughly 40% of that is Acacia optics rather than switching. The shares fell 9% over three months.

What the prices have and have not earned

HPE's is the move with the clearest backing: up 16.7% since the print, including an 11.3% jump on September 11, the session after Oracle detailed its spending. Its trailing enterprise value to EBITDA compressed to 16.9x from above 21x in late August because earnings arrived, not because the price fell, and at 16.2x forward with a 5.1% free-cash-flow yield it is the cheapest and highest-yielding of the three against roughly 10-13x forward in May. Arista, at 50x forward against about 32.5x a year ago, is being paid a rising multiple for growth consensus already models decelerating, by a company that no longer leads its own market on revenue. Cisco, at 21.8x forward versus roughly 18x in May, is expensive against its own pre-AI history and cheap against these peers; the two readings disagree, and both are true.

The binding constraint is not orders. HPE booked $3.1bn of AI orders in the quarter and converted roughly half of that into AI systems revenue, a gap Neri put down to memory supply — DDR5, wafers and clean rooms. The networking company HPE says it is becoming is gated, for now, by a shortage of something it does not make.
