Beñat Turrientes scored the winning goal from close range in the 62nd minute at San Mames Stadium. The return leg will be in March.

Sociedad, playing in its third straight Copa semifinal, is trying to reach the final for the first time since it won the competition in 2019-20 for a third title.

Atletico is in the semifinals for the third straight season, having last reached the final when it won the competition in 2019-20.

Athletic made it to the semifinals thanks to Iñaki Williams's winner six minutes into stoppage time in a 2-1 at Valencia. Sociedad made it to the last four by winning 3-2 at Alaves.
