As of Q2'26 (2026-01-31), ZS reported an EPS Surprise % of -124.14%, marking a significant negative deviation from analyst expectations. The latest EPS Growth (YoY) for the same period stands at -320%, indicating a sharp year-over-year decline in earnings per share. Reviewing the data from Q3'23 to Q2'26, the EPS Surprise % was consistently positive and relatively stable through Q3'24, peaking at 36.73% in Q1'24, before gradually declining and turning sharply negative in Q2'26. Similarly, EPS Growth (YoY) showed strong positive growth through most of the period, with a notable spike to 140.63% in Q3'24, but experienced a dramatic downturn starting in Q3'25, culminating in a substantial negative value by Q2'26. This suggests a recent and significant deterioration in ZS's earnings performance and its ability to meet or exceed market expectations over the last year of the period analyzed.
