NVIDIA, GitLab, Zscaler, PagerDuty by Investing.com

Stock moves by schedule:

NVIDIA (NASDAQ: ) fell 2.1%, extending a 9.5% intraday slide that wiped $279 billion from market value. The after-hours drop was linked in part to a report from Bloomberg that the DOJ had subpoenaed the company as part of a growing antitrust probe. The weakness during the regular session was related to softening optimism about AI.

Zscaler (NASDAQ: ) fell 7% after issuing full-year 2025 EPS guidance that followed estimates.

PagerDuty (NYSE: ) fell 13% after it cut its full-year revenue estimate. For the full fiscal year 2025, total revenue is expected to be $463 million to $467 million (down from $471 million to $477 million).

GitLab ( GTLB ) rose 11% after beating EPS and revenue estimates and raising guidance. Management is confident in its ability to continue to exceed customer expectations and the opportunity it has with AI.

drain (ASAN) fell 12% after announcing the departure of its chief financial officer, along with worse-than-expected earnings and full-year guidance.
