Workday, Palo Alto and Snowflake all rallied on AI, and only one of the three has a rating to match

SNOW jumped 16.6% the day after reporting, against AI's roughly 3.6% gain from a result delivered the same night . The gap was not about AI positioning, which both companies claim. Snowflake posted revenue of $1.55 billion, up 35.1% year over year, beating the consensus $1.47 billion by 4.91%, with EPS of $0.62 against $0.35 a year earlier, a 37.78% surprise, and reported more than 9,100 accounts using its coding agent. C3.ai's revenue fell roughly 25% year over year on a restructuring-driven stabilisation. The differentiator, as the reporting framed it, was whether AI demand appeared in expanding consumption and revenue or mainly in a turnaround narrative.

PANW is the valuation case. Shares have soared 101.8% over six months on genuine product momentum: SASE bookings grew 40% in fiscal 2026 and agentic traffic on the SASE platform increased 9x over the past nine months. But the forward 12-month price-to-sales ratio sits at 18.97X against the Zacks Security industry's 17.14X, and the stock carries a Zacks Rank #3, a Hold, with a Value Score of F. Note what that rank is and is not: it is Zacks' own algorithmic score, not a sell-side analyst action. On the sell-side, SentiSense consensus data puts PANW at a $390.50 average target across 50 analysts, ranging $190.00 to $475.00, with 44 buy against 10 hold and 1 sell.

WDAY beat on both lines and still raised the question the other two dodge. Second-quarter fiscal 2027 non-GAAP earnings came in at $2.75 per share against a $2.62 consensus, up 24.4% from $2.21 a year ago, with revenue up 12.8% to $2.65 billion versus a $2.63 billion estimate. AI products drove over $100 million of new annual contract value, more than 25% of total new ACV, with agentic products growing over 200% year over year. The catch sits in the guide: fiscal 2028 subscription revenue growth of approximately 11%, with non-GAAP operating margin expansion of at least 200 basis points. That is margin discipline paired with decelerating top-line growth, not an acceleration.

Read together, the three are the same trade at different stages. The market has already paid for AI optionality at PANW, where the premium to the industry multiple is explicit and the rank is a Hold. It is paying for demonstrated consumption at SNOW, which also grades a Value Score of F and returned 2% over the preceding month against the S&P 500's -0.1% while its sector gained 4.2%; the shares last traded at $337.18, down 5.4%. And it is still deciding on WDAY, where the AI contribution is real but the fiscal 2028 growth rate is the number that settles it. One caveat worth carrying: Workday's AI-related ARR is reported as both approaching $500 million and approaching $600 million across sources, so treat that specific figure as approximate.
