Zscaler shares fall despite earnings beat as free cash flow slides

Zscaler reported fiscal Q4 revenue of $898.2M, beating estimates of $877M and up 25% YoY, along with adjusted profit topping Wall Street expectations. However, free cash flow fell to $60.8M versus $66.9M expected and dropped 65% YoY, which contributed to the shares declining 3.5%.

Analysis

The market is signaling that, for high-multiple cybersecurity software, cash conversion matters more than top-line beats. That is a near-term de-rating risk not just for ZS but for the broader “quality growth” basket (CRWD, PANW, NET) if investors start demanding visible free-cash-flow discipline instead of paying for revenue acceleration alone. In the short run, this can favor more self-funding names with steadier margin conversion, especially legacy security vendors that can defend valuation on current cash generation.

The second-order issue is that weaker cash generation often reflects one of three things: heavier customer acquisition spend, less favorable working-capital timing, or a shift toward longer-dated contracts that look good on revenue but delay cash. If it is the first, margins may stay under pressure for 1-2 quarters; if it is the second, the signal is mostly noise; if it is the third, it can imply a more fragile billings profile than the revenue print suggests. The missing data is billings/RPO and management commentary on free-cash-flow conversion, which will determine whether this is a one-quarter reset or an early sign of slower monetization.

Contrarian view: the selloff may be too mechanical if the cash dip was driven by timing rather than demand, because the market may be extrapolating one quarter of FCF to a structural slowdown. Still, the stock’s multiple leaves little room for “good enough” execution; unless next quarter shows clear recovery in FCF margin and cash collections, the path of least resistance is lower over the next 1-3 months. The key falsifier is a rebound in FCF conversion back toward prior run-rate and no deterioration in remaining performance obligations or billings growth.

Key Decisions for Investors

• Pair trade: long FTNT / short ZS over the next 1-3 months. FTNT offers cleaner cash generation and lower execution risk; ZS is more exposed to multiple compression if investors keep prioritizing FCF over revenue growth.
• Use any post-earnings bounce in ZS to buy 1-2 month downside protection via put spreads rather than chasing the stock long. Risk/reward favors paying for convexity while the market re-rates cash quality.
• Set a watch item on the next quarter’s billings, RPO, and free-cash-flow margin. If FCF conversion stays below the prior run-rate, treat this as a structural margin-quality issue; if it normalizes, fade the bearish reaction.
