Zscaler: When security becomes a growth driver

2026-05-26 — Q3 FY2026 results and guidance revision; market reaction

Reported Q3 FY2026 revenue of $850.5M, up 25.4% year-over-year, with adjusted EPS of $1.08 beating consensus expectations. Full-year revenue guidance set at $3.329–$3.333B and ARR target around $3.74–$3.75B. Free-cash-flow margin guidance was lowered from earlier targets due to higher capital expenditure, a nuance that unsettled some investors despite the earnings beat. The stock fell on a mixed reaction. [7][10][4]

The market split between those recognizing continued high-growth execution and those concerned about margin and cash-flow cadence. The company's more disciplined but capital-intensive investment posture around AI and security integrations created perception of a growth compounder facing near-term operating leverage questions. [4][12]

Short-term volatility followed the earnings release, with a gap down occurring after a preceding rally into the print.

2026 (H1–H2) — Acquisition-driven product push into AI and EDR

A series of acquisitions bolstered AI, managed detection and response, and zero trust exchange capabilities with AI-driven detection and governance. Red Canary completed in 2025 for approximately $675M; SPLX and other smaller AI and security acquisitions noted across 2025–2026. [9][1][13]

The market viewed the M&A activity as strategically sound, accelerating the product roadmap and expanding total addressable market toward AI and agentic security use cases. Some investors worried about integration costs and near-term free-cash-flow margin dilution. Growth-minded holders accepted the near-term margin tradeoffs as the company reinforced its growth orientation. [9][1][13]

Multi-month consolidation occurred with episodic rallies on deal announcements, and an overall uptrend from early-2025 lows into 2026 was driven by execution news.

2025-08 — Red Canary acquisition closure

Zscaler completed its acquisition of Red Canary, announced earlier in 2025, with deal size reported around $651M–$675M. [9][13]

The acquisition reinforced Zscaler's shift from pure secure web gateway and zero trust network access toward integrated detection and response and SOC augmentation. Investors treated it as transformative for product breadth, broadening the growth story to include managed detection and response with improved cross-sell prospects. [9][13]

A short-term pullback occurred on deal financing and earnings-impact headlines, followed by renewed accumulation as integration details emerged.

2024-03 — Avalor acquisition and AI-driven security data expansion

Zscaler announced and closed the acquisition of Avalor, a data fabric for security platform, to add real-time AI-driven security insights and expand AI security capabilities within the zero trust exchange. [11]

The market viewed this as an early step in embedding AI into the platform's core architecture. Investors increasingly priced the AI narrative into future growth expectations, perceiving Zscaler as a growth compounder with accelerating product innovation. [11]

The stock broke out from a prior range as the market rewarded strategic inorganic moves tied to the AI roadmap.

2024 (FY2024 results) — Strong revenue beats and margin improvement

FY2024 and Q2 FY2024 results reported in the February–March 2024 timeframe delivered revenue beats, with Q2 revenue around $525M, EPS beats, and margin improvement alongside raised full-year outlook. [2][6][14][15]

Execution validated the subscription-based model and improving unit economics. Investors shifted from skepticism about "growth at any cost" toward acknowledging improving profitability and durable ARR expansion. The perception evolved toward a durable cloud-security compounder gaining credibility on profitability. [6][15]

A sustained uptrend through 2024 continued as beats and guidance upgrades supported multiple expansion.

2023 — ARR growth and selective tuck-in acquisitions

Continued ARR growth with smaller acquisitions such as Caconic for supply-chain security and other tuck-ins alongside new product integrations around zero trust. [9]

The market treated Zscaler as a leader in cloud-native zero trust, with perception remaining growth-focused while investors watched spending cadence and margin trajectory. The company was seen as investing to protect long-term total addressable market. [9]

Price action was range-bound to modestly uptrend with punctuations from earnings-driven moves.

2022 — Macro and tech sector sensitivity

Tech sector volatility and interest-rate-driven rotation caused repeated selloffs in high-growth software names, including Zscaler. Earnings still showed ARR growth, but multiples compressed. [6]

Investor focus shifted toward durable revenue growth and path to profitability. Zscaler retained its "growth compounder" label but faced multiple compression until results proved margin expansion was achievable. The perception was of a high-growth name exposed to multiple risk during market derating. [6]

A multi-month downtrend occurred followed by stabilization.

2021 — Post-IPO growth and zero-trust leadership

Post-IPO years brought rapid ARR expansion and customer wins. Zscaler established leadership in cloud-native zero-trust security and scaled subscription revenue. The market perceived a high-growth SaaS security compounder with strong retention and enterprise adoption, with valuation premia justified by total addressable market and subscription economics.

An earlier uptrend reflected the market pricing in rapid ARR growth and leadership position.
