May 7th, 2025, 8:00 PM, multiple stocks experienced significant movements in the US after-hours trading session.

AppLovin Corporation saw its stock price surge by 13.95% in after-hours trading, reaching a high of $54.7.
This significant increase is attributed to the company's impressive first-quarter earnings report and the announcement of the sale of its mobile gaming division to TripleDot Studios. AppLovin reported a 17.64% jump in its stock price post-market after exceeding earnings expectations. The company projected its Q2 advertising revenue to be between $1.195 billion and $1.215 billion, with an adjusted EBITDA forecast of $970 million to $990 million.

Fortinet experienced a sharp decline of 12.39% in after-hours trading.
The cybersecurity firm provided its financial outlook for the fiscal year and Q2, including adjusted operating margin, gross margin, and revenue estimates. Despite reporting strong Q1 results with billings of $1.6 billion and an adjusted EPS of $0.58, surpassing the IBES estimate of $0.53, the stock fell due to concerns over its future financial performance. The FY adjusted operating margin is expected to be 31.5-33.5%, with a gross margin of 79-81%, and revenue forecasted between $6.65 billion and $6.85 billion.

ARM Holdings saw its stock plummet by 11.05% in after-hours trading.
The semiconductor company reported Q4 revenue of $1.241 billion and a net profit of $210 million, with an EPS of $0.20. However, the stock took a hit after ARM projected its Q1 2026 revenue to be between $1 billion and $1.1 billion, falling short of analysts' expectations of $1.1 billion.
