Shares of Yalla Group (NYSE: YALA) tumbled 5.37% in after-hours trading on Monday, despite the company reporting better-than-expected first-quarter results. The Middle East and North Africa (MENA) focused social networking and gaming company posted earnings and revenue that surpassed analyst estimates, yet the stock faced a significant sell-off.

Yalla Group announced quarterly earnings of $0.22 per share, marking a 10% increase from $0.20 per share in the same period last year. The company's quarterly sales reached $83.88 million, beating the analyst consensus estimate of $81.80 million by 2.55%. This represents a 6.54% year-over-year growth from $78.73 million in the previous year's corresponding quarter.

The after-hours plunge in Yalla Group's stock price, despite the positive financial results, suggests that investors may have had even higher expectations or found other concerning factors in the report. It's possible that forward guidance, user growth metrics, or other operational details not mentioned in the brief earnings announcement could have disappointed the market. Investors will likely be looking for more comprehensive information from the company's earnings call to understand the reasons behind this negative reaction.
