JOYY Inc. (JOYY) stock is soaring 5.04% in pre-market trading on Wednesday following the release of its impressive second-quarter 2025 financial results. The global technology company's performance exceeded analyst expectations, particularly in its earnings per share and the growth of its advertising technology business.

JOYY reported non-GAAP earnings of $1.44 per diluted American depository share for Q2, significantly beating the analyst consensus estimate of $0.91. This represents a 23.08% increase from $1.17 per share in the same period last year. While the company's revenue of $507.8 million slightly missed the estimate of $519.82 million, it showed resilience in key areas.

The standout performer in JOYY's Q2 results was its advertising technology business. Non-livestreaming revenue, primarily driven by BIGO Ads, grew an impressive 25.6% year-over-year, now contributing 26.1% of total revenues. This growth underscores JOYY's successful diversification strategy and its emerging strength in the global ad tech market. Additionally, the company provided a positive outlook for Q3 2025, projecting net revenue between $525 million and $539 million, further boosting investor confidence. The strong quarterly performance and optimistic future guidance are likely the key factors driving today's stock surge.
