Zscaler Plunges 32% on Earnings: Overreaction or Reality Check?

What happened

Zscaler shares cratered 32% after its latest earnings release, extending a pattern where strong headline results fail to meet elevated market expectations. The DeepValue report's Q2 FY26 data showed revenue growing 26% and ARR up 25%, but the market increasingly fixates on forward indicators like deferred revenue growth and the pace of multi-year commit deals. Despite the sell-off, the report's base case of $155 implies significant upside from current levels if the company sustains ~24% ARR growth and delivers on FY26 profitability guidance. However, the crash highlights persistent concerns over GAAP operating losses near 6% of revenue and stock-based compensation that dilutes per-share value. The key question is whether the market has overreacted to a single quarter or if it is correctly pricing in a structural deceleration.

Implication

For long-term investors, the thesis remains viable if backlog visibility (RPO >$6B) and FCF margin (~27%) materialize, but must monitor GAAP losses, SBC dilution, and integration of Red Canary—any deterioration in these weakens the re-rating case.

Thesis delta

The earnings crash reinforces the report's assessment that Zscaler is a 'beat-but-sell' story, where forward demand indicators matter more than past results. The sell-off has brought the stock closer to the report's attractive entry ($130), but it also validates the bear-case risk that enterprise deal approvals could slow further. The 32% drop suggests the market is pricing in a higher probability of the bear scenario, making the next quarter's deferred revenue and RPO data critical to reset expectations.
