ZS · Zscaler, Inc.

The thesis

Zscaler's 6 October investor day reaffirmed fiscal 2027 guidance and laid out a path to more than $8 billion of annual recurring revenue (ARR) by fiscal 2031, and the shares have risen with a wave of analyst target raises. The case now rests on the company beating its own guidance. The first-quarter fiscal 2027 report, expected in late November or early December, settles whether revenue clears the $935–939 million guide.

The adjusted close on 8 October 2026 was $216.81. That is 35.5% below the 52-week high of $336.27 and 52.9% above the close three months earlier. On 1 October the close was $198.78.

The investor day did not raise the fiscal 2027 numbers. The company's 6 October release, filed on Form 8-K, reaffirmed revenue of $3.908–3.938 billion (16.6–17.5% growth), ARR of $4.396–4.426 billion (16.6–17.4% growth) and first-quarter revenue of $935–939 million, about 19% growth. Yahoo Finance reported a base case of more than $8 billion ARR by fiscal 2031 and a $10 billion scenario if agentic-AI adoption adds about $2 billion.

The narrative is accelerating again: the investor day gave the story fresh numbers, and at least 16 brokers moved their targets on 7 October (Benzinga). The Cybersecurity group is heating up as well. In this view, the base-case ARR target reads as sustained high-teens growth rather than a return to the 25% of fiscal 2026. The $10 billion scenario is the part that depends on new AI products.

Bullish and bearish views on Zscaler, Inc.

The bull case on Zscaler, Inc. (ZS), in brief: The last quarter beat guidance clearly. The bear case: Growth is still guided to slow.

Bull case

• The last quarter beat guidance clearly. Fourth-quarter fiscal 2026 revenue was $898.2 million against guidance of $875–878 million, and net new ARR was $246 million (3 September release).
• New product lines are now measurable. At the investor day the company said data-security ARR was above $400 million, up 34% in fiscal 2026. Security for AI was about $70 million and Zero Trust Branch and Cloud was $250 million (Yahoo Finance, 6 October).
• Analyst targets reset higher in one day. On 7 October, Stephens raised its target to $265, Wells Fargo to $260 and Scotiabank to $255. Macquarie, UBS, Jefferies, Canaccord, BNP Paribas and Truist each moved to $250, and Citi and JPMorgan to $245 (Benzinga). Amerx started coverage with a $305 target on 8 October.

• Profitability guidance holds. The 6 October release reaffirmed fiscal 2027 non-GAAP operating income of $924–932 million, non-GAAP earnings per share of $4.86–4.90 and a free-cash-flow margin of 23.0–23.5%.

Bear case

• Growth is still guided to slow. Fiscal 2027 revenue growth of 16.6–17.5%, reaffirmed on 6 October, compares with 25% in fiscal 2026, when revenue was $3,352.5 million (Form 10-K).
• The acquisition flatters reported growth. Fourth-quarter ARR growth was 25% including Red Canary's $141 million contribution, or 20% without it (3 September release). The gap closes as the deal passes its anniversary during fiscal 2027.
• Targets sit close to the price. Evercore ISI kept an In-Line rating with a $195 target on 7 October, below the 8 October close. Barclays' $225 and TD Cowen's $230 targets sit less than 7% above that close.
• Sales leadership changed mid-cycle. Chief revenue officer Mike Rich left on 25 September, citing personal circumstances, and the shares fell about 10% to $193.05 that day (MoneyCheck). The first-quarter report is the first under Ross Tackett.
• The company still loses money on a GAAP basis. It reported a fiscal 2026 net loss of $63.2 million (Form 10-K).

Price setup

The 8 October close of $216.81 is above the 25 September close of $193.05 and the 4 September post-earnings close of $169.80. Both of those marked lows in the recovery. The 14-day relative strength index (RSI) was 63.9 on 8 October, below the 70.0 reading on 1 October. The 52-week high of $336.27 is 35.5% above the last close.

The crowding evidence is mostly attention. The shares have gained 52.9% over three months. Sixteen or more target changes landed on a single day, 7 October. The next earnings report is about seven weeks away, so no imminent print is pinning the price. If the shares close below $193.05, they will have given back the investor-day gains and fallen under the post-departure low.

Catalysts, next 30 days

• ~29 October 2026 (est.): Cloudflare third-quarter results. BTIG raised its Cloudflare target to $413 on 7 October, citing stronger growth (Benzinga). A strong report would support demand for security delivered from the cloud.
• ~5 November 2026 (est.): Fortinet third-quarter results. This is a read on firewall and secure-access spending from a direct competitor.
• ~24 November to 3 December 2026 (est.): Zscaler first-quarter fiscal 2027 results. Revenue is guided at $935–939 million and non-GAAP EPS at $1.15–1.16. This is the report the case turns on, and it falls just beyond the 30-day window.

What would change the view

The case breaks if first-quarter fiscal 2027 revenue comes in under the $935 million guidance floor, or if the fiscal 2027 range is trimmed rather than raised at that report. It also weakens if organic ARR growth, excluding Red Canary, falls below the 20% of the fourth quarter of fiscal 2026. Net new ARR below the $246 million of that quarter would count against it too. Another senior sales departure would turn the 25 September change from a one-off into a pattern. On price, a weekly close below $193.05, the 25 September 2026 close, would erase the investor-day rally.

What it trades with

Zscaler trades with large-cap security software. Its closest peers are CrowdStrike, Palo Alto Networks, Cloudflare and Netskope. Okta, SentinelOne and Rubrik also move with sector sentiment. The Cybersecurity group turned up again in the week of 9 October. On 8 October, US agencies warned that a China-based security company was enabling attacks on critical infrastructure (Benzinga), which keeps security spending in the headlines. The shares are also sensitive to bond yields, because much of the valuation rests on cash flows years out. If peers guide below consensus during November reporting, the group's momentum would fade and the bar for Zscaler's own report would rise.
