Hewlett Packard Enterprise (HPE) agreed to buy supercomputer maker Cray Inc. for $35 per share in cash on May 17, 2019. HPE valued the transaction at approximately $1.3 billion net of cash at announcement and completed it on September 25, 2019. The deal was intended to combine Cray’s supercomputing technology and expertise with HPE’s enterprise reach, particularly for data-intensive high-performance computing (HPC), artificial intelligence (AI), modeling, simulation and analytics workloads.

What HPE announced in May 2019

HPE and Cray announced a definitive merger agreement on May 17, 2019. Cray shareholders were to receive $35.00 per share in cash. HPE’s announcement described the transaction as worth approximately $1.3 billion, net of cash.

The announcement framed the purchase as a strategic expansion of HPE’s HPC and AI portfolio rather than as a conventional enterprise-software acquisition. Cray brought specialized supercomputing engineering, systems expertise and technologies designed for workloads that require very large amounts of compute, memory, networking and data movement.

Announcement value and closing value are different figures

HPE later reported a different approximate net-of-cash value when the transaction closed. The two figures should be kept tied to their respective company announcements rather than treated as contradictory prices for the same date.

Date Event Terms or valuation stated by HPE
May 17, 2019 Definitive agreement announced $35.00 per Cray share in cash; approximately $1.3 billion net of cash
September 25, 2019 Acquisition completed Approximately $1.4 billion net of cash in HPE’s completion announcement

The available announcements establish the two reported values but do not provide an accounting bridge explaining why the approximate net-of-cash figure changed. It is therefore safer not to infer a revised per-share price or speculate about the difference.

Why HPE wanted Cray

Adding supercomputing depth to HPE’s portfolio

HPE said Cray’s talent and technology would strengthen its ability to address data-intensive customer problems. The stated target areas included modeling and simulation, AI and analytics, alongside traditional HPC workloads.

Combining enterprise reach with specialized systems

HPE presented the combination as a way to pair its broader enterprise sales, services and infrastructure presence with Cray’s experience building and integrating large-scale supercomputers. That was HPE’s strategic rationale and a projection of potential benefits, not independent evidence that every anticipated outcome occurred.

High-speed networking and software

Among the technologies HPE highlighted was Cray’s Slingshot interconnect, intended for high-performance data movement at scale. HPE also pointed to Cray’s cloud-native software stacks as part of the combined offering.

Expanding access through services

HPE’s announcement described an ambition to broaden access to supercomputing through service offerings. Contemporary coverage by CRN discussed HPC-as-a-Service through HPE GreenLake as a possible direction. That 2019 discussion should not be read as confirmation of current GreenLake availability, pricing, eligibility or partner terms.

What products and platforms were in the 2019 story?

At the time of the agreement, HPE described Cray’s current-generation XE and CS platforms and its next-generation Shasta series. Slingshot was presented as a key interconnect technology across the company’s supercomputing roadmap.

Those labels describe the product context in 2019, not guaranteed current specifications. HPE’s later company materials identify Cray as a brand of supercomputing solutions within Hewlett Packard Enterprise, and HPE’s FY2025 annual report includes HPE Cray EX solutions and systems in its supercomputing portfolio. The later references establish brand and portfolio continuity; they should not be used to retrofit 2019 performance or feature claims.

When did HPE complete the Cray acquisition?

HPE announced completion on September 25, 2019, earlier than its original target. The completion announcement described the transaction as approximately $1.4 billion net of cash. Completion confirms that ownership changed hands; it does not, by itself, demonstrate that HPE achieved each strategic benefit forecast in May.

What the deal said about the HPC market

In the May 2019 announcement, HPE estimated that the HPC segment, together with associated storage and services, represented approximately $28 billion in 2018 and could reach approximately $35 billion in 2021, implying approximately 9% expected growth over three years. These were HPE’s dated estimates and forecast, not a current market measurement. They are useful for understanding the business case HPE presented when it made the offer.

How to interpret HPE’s “Exascale era” claim

HPE CEO Antonio Neri said in the May 2019 acquisition announcement: “The real value of this acquisition is what we can create together and I can’t wait to see these two great companies lead the Exascale era of high-performance computing.”

The quotation captures HPE’s outlook at announcement. It is not a measurement of post-acquisition performance, a promise of a particular system delivery date or proof that the combined company achieved exascale computing.

What the acquisition means for readers today

A corporate integration, not a consumer product launch

This was an enterprise infrastructure acquisition. The deal did not create a consumer PC, a retail accessory or a generally available product that an individual buyer could purchase through ordinary online shopping.

Cray remains part of HPE’s supercomputing identity

HPE’s later materials use HPE Cray as a brand within its supercomputing portfolio. That current branding helps explain where Cray fits inside HPE, while the original announcement remains the authoritative source for the 2019 offer terms and strategic intent.

Service claims require current documentation

GreenLake HPC-as-a-Service was a contemporaneous commercial possibility discussed around the deal. Anyone evaluating a service today would need current HPE documentation covering region, configuration, eligibility, pricing and contracting; the 2019 acquisition announcement does not establish those terms.

Key takeaways

  • HPE announced the Cray acquisition on May 17, 2019, offering $35.00 per share in cash.
  • The announcement valued the deal at approximately $1.3 billion net of cash.
  • HPE completed the acquisition on September 25, 2019, and its completion announcement used an approximately $1.4 billion net-of-cash value.
  • HPE’s stated objective was to expand HPC and AI capabilities for data-intensive workloads by combining HPE’s enterprise platform with Cray’s supercomputing technology and talent.
  • Cray’s Slingshot interconnect, XE and CS platforms, and Shasta roadmap were part of the 2019 product context.
  • HPC-as-a-Service through GreenLake was discussed as a possible direction in 2019; current service terms are not established by that coverage.
  • HPE’s $28 billion, $35 billion and 9% figures were company estimates and a forecast from 2019, not present-day market data.
