Public view, delayed 4h. Every headline, price and sentiment read below — and this write-up itself — reaches Pro subscribers live. Public readers see it once it clears the delay.

ZS stock is down 5.92% at $167.28 in the session, driven by a sharp selloff following earnings and guidance despite strong Q4 results. The cybersecurity firm reported revenue of $898.2 million, exceeding estimates, and adjusted earnings per share of $1.19, above expectations. However, the stock reacted negatively to FY2027 growth guidance, which some investors found insufficient to justify current valuations. The sector-wide pullback also contributed to the decline, with ZS trading below its 52-week high and underperforming broader market sentiment.

What Happened

Zscaler’s stock opened at $174.20, a 2.0% gap down from the previous close, and quickly fell to a session low of $165.06. The decline followed the release of its Q4 earnings and FY2027 guidance, which, while positive, failed to meet the heightened expectations of investors. Analysts at FBN Securities raised their price target on ZS, and BMO Capital maintained an Outperform rating with a $200 price target. However, the broader cybersecurity sector saw a pullback, with Zscaler leading the decline. The stock closed the session at $167.28, down 5.92%, despite a clean earnings beat and upbeat guidance. Piper Sandler and Morgan Stanley also raised their price targets, but the market reaction remained bearish.

What The Data Shows

ZS has traded within a wide 52-week range of $114.63 to $336.99, and currently sits at $167.28, down approximately 20% year to date. The stock has seen a volume of 4.4 million shares so far in the session, 1.2 times the 3-month average. The price trend over the last 8 sessions was relatively flat, with a slight increase from $170.31 to $170.46. Recent insider transactions include multiple sales by the CFO and other executives, totaling $2.7 million in the last 90 days. Congressional trades show a mix of buys and sells, with no clear pattern influencing the stock’s movement.

What To Watch

Zscaler has no scheduled earnings in the near term, but coverage breadth remains high with 65 stories from 17 sources in the last 36 hours. Investors will be watching for further analyst commentary and how the stock reacts to the broader cybersecurity sector and macroeconomic conditions.

Zscaler Agentic SOC Goes Live as ZS Guides to 17% ARR Growth

Zscaler has handed its cloud-security platform a new job: let software agents investigate incidents and trigger containment before an analyst finishes triage. Agentic SOC became globally available on September 9, but the launch gave investors a capability list—not a price, contract value or revenue target. That omission defines the next test for ZS stock.
