Zscaler Inc. (NASDAQ: ZS) saw its shares surge 5.07% in after-hours trading on Thursday, following the release of its third-quarter fiscal 2025 financial results that exceeded analyst expectations, along with an optimistic outlook and the announcement of a key executive appointment.

For the quarter ended April 30, 2025, Zscaler reported adjusted earnings per share of $0.84, significantly beating the consensus estimate of $0.75. Revenue came in at $678.03 million, surpassing the expected $666.86 million and representing a 22.57% increase from the same period last year. The company's calculated billings, a key metric for future revenue, grew by 25% year-over-year to $784.5 million.

Adding to the positive sentiment, Zscaler provided strong guidance for both the fourth quarter and full fiscal year 2025. The company raised its full-year outlook, now expecting revenue between $2.659 billion and $2.661 billion, up from its previous forecast of $2.640 billion to $2.654 billion. Non-GAAP earnings per share for the full year are projected at $3.18 to $3.19, higher than the earlier guidance of $3.04 to $3.09. Both figures surpassed analyst expectations, demonstrating the company's confidence in its growth trajectory.

In a separate announcement, Zscaler named Kevin Rubin as its new Chief Financial Officer. Rubin, who brings extensive experience from his previous roles at companies like BetterUp and Alteryx, will succeed Remo Canessa. This strategic appointment is seen as a positive move to support Zscaler's next phase of growth and innovation in the cybersecurity space.

The combination of strong financial performance, optimistic future guidance, and the addition of a seasoned financial executive to the leadership team has clearly resonated with investors. As organizations continue to prioritize cloud security and zero-trust architectures, Zscaler appears well-positioned to capitalize on these trends and maintain its growth momentum in the cybersecurity market.
