Fortinet's stock skyrocketed by more than 23% after the company reported Q1 billings of $2.09 billion, surpassing analyst expectations of $1.82 billion. This strong financial performance, highlighted by a year-over-year revenue growth of 20.1% and a non-GAAP operating margin of 35.8%, has positioned Fortinet as a top gainer in pre-market trading. The surge reaffirms investor confidence in the cybersecurity firm, which has recovered from a 38.3% stock drop during the 2023 inflation shock.
