Read MoreHide Full Article

A month has gone by since the last earnings report for Palo Alto Networks (PANW - Free Report) . Shares have added about 21% in that time frame, outperforming the S&P 500.

But investors have to be wondering, will the recent positive trend continue leading up to its next earnings release, or is Palo Alto due for a pullback? Before we dive into how investors and analysts have reacted as of late, let's take a quick look at its latest earnings report in order to get a better handle on the important catalysts.

PANW Q4 Earnings Beat Estimates on Platformization Strength

Palo Alto Networks delivered fourth-quarter fiscal 2026 non-GAAP earnings of $1.02 per share, which beat the Zacks Consensus Estimate by 4.1%. The figure improved 7.4% year over year.

Revenues climbed 34% year over year to $3.41 billion and topped the consensus estimate by 1.8%. Broad-based strength across Network & AI Security, Cortex and Idira, along with record platformization adoption, drove the fourth-quarter results. Next-Generation Security ARR jumped 63% to $9.10 billion.

PANW's Revenue Mix Shows Broad-Based Growth

Product revenues increased 28.6% year over year to $738 million from $574 million in the year-ago quarter, accounting for 21.6% of total revenues. Subscription and support revenues rose 36.2% to $2.672 billion from $1.962 billion, which represented 78.4% of total revenues.

By platform, fourth-quarter revenues were $2.331 billion for Network & AI Security, $586 million for Cortex and $336 million for Idira. Other revenues, including Unit 42, professional services and financing income, totaled $157 million.

Palo Alto Networks' Platformization Hits Record Levels

Remaining performance obligations rose 34% year over year to $21.2 billion. Net new NGS ARR reached approximately $970 million, up 98% year over year, reflecting the strongest quarterly addition reported by the company.

Palo Alto Networks added roughly 220 net new platformizations in the quarter, up 44% year over year. Net revenue retention among platformized customers, excluding Identity and Observability, exceeded 120%, while more than 65% of NGS ARR came from platformized customers.

PANW's AI Security Products Gain Scale

Prisma AIRS reached roughly $120 million in ARR within one year of general availability and had over 800 customers, more than doubling sequentially. Software firewall ARR grew 29% year over year, while SASE competitive displacements totaled about $450 million in fiscal 2026.

Cortex momentum also remained strong. XSIAM ARR exceeded $700 million and grew about 70% year over year, while observability ARR surpassed $500 million and increased more than 2.5 times from the second quarter. CyberArk, now called Idira, generated more than 200 new-logo wins from PANW's installed base.

Palo Alto Networks' Margins Reflect SaaS Mix Shift

Non-GAAP gross profit was $2.552 billion, with gross margin at 74.8%, down from 75.8% a year earlier. Management attributed the pressure to a mix shift toward faster-growing SaaS offerings that have not yet reached gross-margin maturity.

Non-GAAP operating income was $1.011 billion, translating to a 29.6% margin compared with 30.3% a year ago.

Adjusted free cash flow increased to $1.289 billion from $954 million, with margin edging up to 37.8% from 37.6%. Cash and cash equivalents stood at $2.514 billion, with $557 million in short-term investments.

PANW Guides Strong Growth for Fiscal 2027

For the first quarter of fiscal 2027, Palo Alto Networks expects revenues of $3.300-$3.310 billion, indicating 33-34% growth. NGS ARR is projected to be in the range of $9.54-$9.56 billion, RPO in the band of $20.8-$20.9 billion and non-GAAP earnings per share between 96 cents and 98 cents.

For fiscal 2027, revenues are forecast at $14.10-$14.20 billion, implying 23-24% growth. NGS ARR is expected to be in the range of $11.075-$11.175 billion, RPO in the band of $25.2-$25.4 billion and non-GAAP earnings per share between $4.16 and $4.19. The company targets a 29.5% non-GAAP operating margin and a 38.0% adjusted free cash flow margin.

Palo Alto Networks Maps Platform Growth Ahead

Management expects fiscal 2027 Network & AI Security revenues to grow in the low double digits, Cortex revenues to rise about 30%, and Idira revenues to reach approximately $1.5 billion, implying pro forma growth in the high teens to 20%.

The company expects 60-61% of fiscal 2027 net new NGS ARR to arrive in the second half. Its outlook assumes the tail end of a large LLM customer's migration to Chronosphere continues through the first quarter, but contributes less net new ARR than it did in the fourth quarter.
