Pure Storage (PSTG) Research Dashboard

Pure Storage $PSTG

Kerrisdale Capital • Published September 2025 • "A Flash in the Pan"

CORE INVESTMENT THESIS

Pure Storage is a "melting ice cube" with declining competitive differentiation and poor positioning for AI infrastructure spending.

After riding the all-flash array adoption wave, Pure faces modest growth, weak hyperscaler prospects, and margin pressures. The company's TCO claims are flawed, and "the purest thing about PSTG shares is pure downside."

WARNING SIGNS

Declining RPO Growth

Remaining Performance Obligation growth has suffered a "step function decline" over the past six quarters, dropping from consistent 25%+ to current levels.

Margin Pressure

Pure//E products targeting HDD displacement will have "low-to-mid 40s" gross margins, threatening the 70%+ margins that justify SaaS-like valuations.

Accounting Concerns

Extended asset amortization periods and stock-based compensation representing 56% of cash flow. Recent CFO departure adds uncertainty.

Flash Industry Reality

Major flash suppliers cutting production in 2025. Industry needs $200B investment to displace 2027 HDD shipments, but capacity is shifting to HBM instead.
