Electronic Arts Inc. (EA) experienced a significant stock decline of 19% on Thursday, marking its worst day since the dot-com bubble, following a disappointing preliminary fiscal third-quarter report. The company cited underperformance in its key franchises, EA Sports FC and Dragon Age: The Veilguard, as the primary reasons for the downturn. EA Sports FC, previously known as FIFA, saw a slowdown in its Global Football business, which led to a revision in the company's full-year net bookings forecast from $7.5 billion to $7.8 billion down to $7 billion to $7.15 billion. Dragon Age: The Veilguard engaged 1.5 million players during the quarter, falling nearly 50% short of EA's expectations. The company also reported a third-quarter net booking of approximately $2.215 billion, below the previously guided range of $2.4 billion to $2.55 billion.
