Zscaler's Growth Slowdown and Margin Pressure

Zscaler closed fiscal 2026 with revenue of $898.2 million, a 25% year-over-year increase, while total annual recurring revenue reached $3.8 billion. Despite this headline growth, the company's net new ARR excluding the Red Canary acquisition grew just 17% in the fourth quarter. This figure marks a sharp slowdown compared to the 62% deferred revenue growth seen as recently as fiscal 2022, indicating that underlying billings are cooling faster than recognized revenue.

The divergence between recognized revenue and billings is evident in the deferred revenue line item. Growth in total deferred revenue has declined annually since fiscal 2022, dropping to 18.5% in fiscal 2026. This rate is now lower than the company’s 25% revenue growth, a first in the available data. Management attributes the upcoming fiscal 2027 slowdown to sales leadership transitions and timing, though the billings trend suggests the deceleration was already underway before the official guidance was issued.

Infrastructure costs erode cash margins

While non-GAAP operating margin expanded to 22.9% in fiscal 2026, free cash flow growth lagged significantly behind revenue. Free cash flow increased by only 5.5% to $852.4 million, causing the FCF margin to drop nearly 500 basis points to 25.4%. CFO Kevin Rubin cited rising prices for memory, storage, and processors as the primary driver, noting that Zscaler accelerated data center equipment purchases in the fourth quarter to secure supply where available.

Capital expenditure reached 8% of revenue for the full year, sitting at the high end of the company's previous flags. Management guides for further margin compression in fiscal 2027 as data center capital expenditures continue to outpace revenue growth. This structural increase in infrastructure costs is a key factor in the company's current valuation adjustments, as investors adjust for the higher capital intensity required to support the cloud security platform.

Valuation reflects slower growth expectations

Zscaler's next twelve months price-to-earnings multiple has compressed to approximately 40x, down from a four-year average near 64x and historical highs above 100x. This de-rating occurs before fiscal 2027 begins, suggesting that the market has already priced in the expected cooling of net new ARR growth to the high-teens or lower range. The stock's recent performance reflects a shift in expectations regarding the pace of enterprise adoption for newer security products.

According to reporting from GN markets/earnings, the company's guidance implies net new ARR growth of roughly 4% in the coming period, a significant reversal from the 17% posted in the most recent quarter. Analysts note that the non-current deferred revenue segment, tied to multiyear commitments, grew only 7.7% in fiscal 2026 after a 65% jump the prior year. This discrepancy may reflect billing structures for Z-Flex contracts, which are billed annually rather than upfront, complicating the verification of long-term commitment trends through standard accounting lines.

Sales model changes impact results

Management frames the fourth quarter's 17% net new ARR growth as evidence that its account-focused sales reorganization is functioning. This model, built around Chief Revenue Officer Mike Rich, aims to improve conversion rates and expand penetration within existing enterprise accounts. However, the immediate guidance for fiscal 2027 suggests that the benefits of this restructuring have not yet fully materialized in the billings data, with leadership transitions continuing to weigh on execution.

The company recorded a record $1.7 billion in Z-Flex bookings during fiscal 2026, a multiyear commitment product designed to lock in enterprise customers. Yet, the sluggish growth in non-current deferred revenue indicates that these deals are not translating into immediate cash inflows or recognized revenue at the pace previously assumed. This structural shift in how deals are billed and recognized adds complexity to evaluating the company's true underlying demand, requiring investors to look beyond top-line revenue growth for a clearer picture of future cash generation.
