Pure Storage: An Exciting AI Data Center Infrastructure Opportunity

Pure Storage has a strong product advantage as a pure play AI native energy efficient storage market leader with massive growth.

Pure Storage (PSTG) $75 A good long term opportunity, buying the stock.

The buy the dip opportunity:

Pure Storage’s banishment to the dog house with a 27% post-earnings drop from $94 to $69 is an opportunity. It has recovered to around $75, but still has a long way to go.

Not surprisingly, the short sighted sell-off was triggered by management’s plans to increase R&D and sales spending in the current year, which would only be accretive to revenues and earnings in FY2027. Strangely, no one realized that the downtick in margins was only for a year. This industry needs product development. As AI and data centers progress the emphasis on reducing energy costs will produce the winners, and it makes no sense for Pure Storage to not develop energy saving storage arrays for hyper scalers like Meta.

Margins will recover in 2027:

Despite increased spending, management explicitly expects operating margin expansion. For example, Meta, one of its largest clients, will give Pure Storage high margin royalty revenues. Pure designs storage arrays for Meta, built by an OEM, Kioxia, the design and technology provides them recurring royalty based on the amount of storage delivered to Meta. We may see comparatively lower revenue growth, because Pure will count revenue income from royalties and not the full product sales, and one should be able to discern that compared to prior years. We will see that in higher net incomes and earnings.

A recurring subscription business:

The shift to a software type subscription model for storage is absolutely the right way to group. The uncertainty created by this pivot is worth it if it improves revenue and margins and Pure Storage has to offer a competitive edge and differentiation..

Product Differentiation:

Pure’s proprietary DirectFlash technology has an energy-efficient edge over incumbents like Dell. It is supposedly 10x more energy-efficient and requires 80% less rack space, a competitive advantage for power-constrained AI data centers.  Pure has a fast product cadence emphasizing continuous improvements over competitors like Dell for energy efficiency.

Capturing the technology shift: The need for efficient power

The industry is shifting from legacy "spinning disks" which is still over 40% of the storage market. Their new products such as FlashBlade//EXA have been made for the "Neo-Cloud" and AI inference markets, underscoring a competitive advantage over legacy suppliers with other large businesses. This trend to all Flash memory storage is like to continue for a while for energy efficiency, since direct flash consumes less energy than hard disc drives, and Pure has always designed its arrays to optimize power consumption, heat dissipation, and space requirements. It is a Pure play storage company with much higher focus than a commodity producer. One could call it AI native. Storage's higher inventory of components is a smart hedge to ensure that they have enough supply.

Challenges:

This is heavily reliant on data center buildouts, competitive with giants like Dell in the mix and will always have the threat of obsolescence, as we can see how the legacy spin disks getting shunted out. The financial challenge is also to get a better GAAP profitable margin for a better valuation, as a $4Bn revenue company, investors need to see more profitability,

Valuation:

PSTG sells for 31x earnings growing over 18%, with a great chance of exceeding this growth rate, revenues are expected to grow at 15-16% in the next three years, with a P/S ratio of 5.6, which is also reasonable.
