Zscaler’s SWOT analysis: cloud security leader’s stock poised for growth

Zscaler (ZS) reported robust F3Q25 results, with revenue growing 23% year-over-year to $678 million and billings up 25%, leading to an upward revision of FY25 guidance for revenue to $2.659B-$2.661B and non-GAAP EPS to $3.18-$3.19. The company is strategically shifting to an ARR-centric reporting model from FY26, projecting $3.5 billion in ARR, and is leveraging its Z-Flex program and product innovations to capitalize on strong demand in the Zero Trust and SASE markets. Despite facing intensifying competition and integration risks from the Red Canary acquisition, Zscaler's consistent performance and strategic growth initiatives underpin its positive outlook, tempered by broader macroeconomic uncertainties.

Analysis

Zscaler, Inc. (ZS) demonstrated robust operational momentum in its fiscal third quarter of 2025, reporting a 23% year-over-year revenue increase to $678.0 million and a 25% YoY growth in billings, both surpassing consensus estimates. This performance, coupled with a strong gross margin of 77% and a healthy current ratio of 2.01, prompted management to raise full-year FY25 guidance. The company now projects revenue between $2.659 billion and $2.661 billion (23% YoY growth) and billings up to $3.189 billion (21% YoY growth), an outlook supported by 21 analysts revising their earnings estimates upward. Strategically, Zscaler is positioning for future growth by transitioning to Annual Recurring Revenue (ARR) as its primary metric in FY26, with analyst projections targeting $3.5 billion. The new Z-Flex consumption model is showing early traction, generating $65 million in Total Contract Value bookings shortly after launch, indicating its potential to lower entry barriers and accelerate adoption. Despite its strong position in the growing Zero Trust and SASE markets, Zscaler faces material risks from intensifying competition, which could lead to pricing pressure and service commoditization. Additional headwinds include integration risks associated with the Red Canary acquisition and a planned $70 million ARR churn from non-enterprise clients, alongside macroeconomic uncertainty impacting IT spending.

Key Decisions for Investors

• Given the stock is trading slightly above its perceived Fair Value despite strong performance, investors should carefully evaluate entry points, balancing the premium valuation against the company's consistent growth and raised guidance.
• Monitor the execution of key strategic initiatives, particularly the customer adoption and revenue contribution from the Z-Flex program and the planned transition to ARR-based reporting in FY26, which will be critical for long-term valuation.
• Closely track competitive dynamics within the SASE market for any signs of pricing pressure or market share erosion, as this is identified as a primary long-term risk.
• Assess the integration of the Red Canary acquisition, including management's ability to successfully navigate the intentional churn of $70 million in ARR without disrupting broader operations or market perception.
