Zscaler's Profitability Milestone Fails to Thaw Investor Frost Amid Growth Deceleration

Zscaler beats Q3 estimates but stock crashes 27% amid analyst downgrades, slower growth forecast, and free cash flow margin cuts.

The market's verdict on Zscaler's latest quarter is in, and it's not pretty. Despite delivering a record operating margin and beating consensus estimates on both profit and revenue, the cybersecurity specialist has seen its stock pummeled. The culprit lies not in the rearview mirror, but on the road ahead: a markedly slower growth trajectory for fiscal 2027 and a squeeze on free cash flow that has rattled confidence.

Shares of Zscaler traded at €114.46 on Friday, climbing 2.36% on the day — a modest reprieve from a seven-day rout that wiped out 27.29% of the stock's value. Year to date, the equity is down 39.19%, and it now sits roughly 60.80% below the 52-week high set last year.

The sell-off gained fresh momentum after a flurry of analyst downgrades and price target cuts. Evercore ISI made the most aggressive move, slashing its rating from "Outperform" to "In Line" and pruning its target from $225 to $155. The bank pointed to a shake-up in Zscaler's sales leadership and a softer-than-expected outlook for fiscal 2027 as the rationale. Other shops followed suit: TD Cowen lowered its target from $220 to $180, Truist Securities cut from $250 to $200, and Freedom Broker reduced its price objective from $270 to $230 while maintaining a buy recommendation. RBC Capital Markets held its target steady at $205.

All this, despite a third quarter that on its face looked strong. Adjusted earnings per share came in at $1.08, a 28.6% increase from a year ago and a tidy beat over the $1.00 consensus. Revenue jumped 25% to $850.4 million, topping the Zacks consensus estimate of $834 million. The annual recurring revenue (ARR) hit $3.525 billion, also up 25%, though organic growth excluding the Red Canary acquisition was 21%.

Profitability stole the spotlight. Zscaler's non-GAAP operating margin reached 23% — a company record — up from 22% in the prior-year period. The non-GAAP operating income amounted to $195.8 million. For a growth-oriented software company, such margin expansion is a clear signal of operational discipline.

But the cash flow story told a different tune. Operating cash flow for the quarter fell to $198 million, representing 23% of revenue, compared with 31% in the same quarter last year. The company also revised its free cash flow margin guidance for the full year downward, now expecting 22.8% to 23.3%, a steep drop from the previously forecast 26.5% to 27%. Higher investments were cited as the reason, and investors clearly took note.

Zscaler management tried to cushion the blow by raising its fiscal 2026 revenue forecast to a range of $3.3295 billion to $3.3325 billion, and guiding adjusted earnings per share to $4.10–$4.11. Yet these near-term upgrades did little to counter the anxiety over what lies beyond.

For fiscal 2027, the company has signaled ARR and revenue growth of 16% to 17%, a deceleration that sits below some market expectations. Adding to the caution is a change in sales leadership, which naturally injects uncertainty into execution. The combination of slower growth and elevated spending to fuel an AI security pivot is forcing analysts to reassess the stock's valuation multiples.

On the product side, Zscaler is pressing ahead with artificial intelligence initiatives. The planned acquisition of Symmetry Systems will bring access-graph technology into its Zero Trust Exchange platform, giving customers finer control over data permissions and machine-to-machine communications. Project AI-Guardian, meanwhile, extends partnerships with global system integrators to help enterprises deploy AI safely. These moves are strategically sound but require upfront capital — further straining the cash flow narrative.

The company ended the quarter with $3.39 billion in cash and investments, leaving it with ample liquidity. But until the higher spend translates into reaccelerated growth and stronger cash generation, the stock may remain under pressure. The next catalyst — the fiscal fourth-quarter report, expected around August — will need to show that the AI security bet is paying off. For now, the market is demanding proof, not promises.
