On August 14, Palo Alto Networks fell 3.18% in regular trading, trading at 382.81 USD/share, with turnover of 3.01 billion USD. The decline came as the broader systems software sector faced selling pressure, compounded by lingering uncertainty from China's cybersecurity review of the company's domestically sold products.

China's Cybersecurity Review Office previously launched a formal review of Palo Alto Networks' products sold in China, citing the need to safeguard critical information infrastructure security under national cybersecurity laws. While the initial shock from the August 6 announcement has been partially absorbed, the unclear timeline and outcome of the review continue to weigh on the company's China-region business outlook.

Additionally, with the stock having accumulated gains approaching 100% year-to-date, profit-taking pressure has intensified ahead of its fiscal Q4 earnings release scheduled for September 1. The systems software sector broadly declined, with peers CrowdStrike down 3.31% and ServiceNow down 3.61%, reinforcing sector-wide headwinds.
