Reddit Inc. reported its fourth-quarter earnings, surpassing expectations on revenue and earnings per share. The company's revenue reached $427.7 million, marking a 71% increase year-over-year, and beating the estimate of $405.3 million. Earnings per share were $0.36, compared to the expected $0.25. However, daily active unique visitors rose 39% to 101.7 million, falling short of the anticipated 103.1 million. This miss on user growth led to a significant after-hours drop in Reddit's stock price, declining by more than 15%. The company attributed some of the user growth volatility to a change in Google's search algorithm during the quarter, although it noted that search-related traffic has since recovered. Reddit's first-quarter revenue guidance is set between $360 million and $370 million, which is above the average analyst estimate of $358 million. The company's net income for the quarter was $71 million, nearly quadrupling from the previous year's $18.5 million.
