How did UMC's Q4 earnings surprise investors?

UMC's Q4 earnings report revealed a mixed sentiment among investors, as the company's financial performance was both impressive and disappointing. 1. **Revenue Growth Amid Challenges**: UMC reported a solid financial performance with a revenue of NT$50.5 billion, showcasing strong revenue growth amid market challenges. This indicates a positive aspect of the company's performance, which could have been seen as a surprise positive. 2. **Earnings Miss Expectations**: However, UMC's fourth quarter earnings fell short of analyst estimates, with a net income of $258 million, representing a significant quarter-over-quarter decline of 43.46%. This earnings miss likely contributed to the negative sentiment, surprising investors with weaker profitability than anticipated. |code|Ticker|Name|Date|Percentage Change|Percentage Change YoY|market_code| |---|---|---|---|---|---|---| |UMC|UMC.N|UMC|20240102|-2.1277||169| |UMC|UMC.N|UMC|20240103|-2.8986||169| |UMC|UMC.N|UMC|20240104|1.1194||169| |UMC|UMC.N|UMC|20240105|-0.369||169| |UMC|UMC.N|UMC|20240108|1.6049||169| |UMC|UMC.N|UMC|20240109|-1.4581||169| |UMC|UMC.N|UMC|20240110|-0.8631||169| |UMC|UMC.N|UMC|20240111|-0.7463||169| |UMC|UMC.N|UMC|20240112|-0.3759||169| |UMC|UMC.N|UMC|20240116|-1.5094||169| 3. **Stock Performance**: Despite the earnings miss, UMC shares rose by 1.59% in after-hours trading following the report.
