Zscaler (ZS) concentration risks

The company's disclosed concentration profile is narrow, anchored by a single channel-partner dependency: sales through the top five channel partners and their affiliates, in aggregate, represented 28% of revenue for fiscal 2025, a moderate share by disclosed size. This is a go-to-market structural feature rather than an end-customer dependency. The company sells primarily through indirect channels, meaning this concentration reflects the distribution intermediaries rather than the underlying enterprise buyers, which are typically large organizations distributed broadly across sectors and geographies. The dependency character of the exposure reflects the fact that a meaningful reallocation of business by these channel partners — or a deterioration in the working relationships — could affect the company's ability to source and close deals efficiently. The filing does not disclose any named geographic, supplier, or product concentration beyond this channel-level exposure. The absence of individual named partners in the cited disclosure further limits the ability to assess single-name risk within the cohort, but also suggests no individual partner relationship approaches a threshold that would create acute dependency on its own. On balance, the disclosed concentration profile is contained: the top-five channel partner relationship is the primary variable to monitor, and the structural nature of indirect distribution in enterprise software means this level of intermediary concentration is a common feature of the sector rather than an anomalous risk.
