Pure Storage stock falls after Kerrisdale announces short position

Investing.com -- Pure Storage (NYSE: PSTG) stock fell 3% Thursday morning after hedge fund Kerrisdale Capital announced it had taken a short position in the enterprise storage company.

Kerrisdale released a detailed report criticizing Pure Storage’s $27 billion market valuation and questioning its growth prospects. The hedge fund argued that Pure Storage faces declining competitive differentiation and has a product portfolio poorly positioned to capitalize on cloud or AI infrastructure spending.

The report directly challenged Pure’s narrative around its quad-level cell (QLC) flash-based products, claiming they won’t displace hard disk drives (HDDs) in hyperscaler environments as the company suggests. Kerrisdale conducted its own total cost of ownership analysis and concluded that HDDs maintain a "5-6x TCO advantage versus flash-based solutions."

Kerrisdale also expressed skepticism about Pure’s recent software licensing deal with Meta, suggesting the capabilities provided are "narrow and replicable" and that Meta won’t be purchasing Pure’s hardware products.

In the enterprise storage market, which represents Pure’s core business, Kerrisdale described competition as "knife fights in phone booths" with little opportunity for meaningful market share gains against competitors like Dell, Hewlett Packard Enterprise, and NetApp.

The hedge fund further argued that Pure Storage’s "software" business consists primarily of maintenance, support, and pre-purchased upgrade revenue that doesn’t merit the SaaS valuation multiple that bulls have assigned to the company.

Pure Storage shares have gained approximately 25% year-to-date despite today’s decline.
